He mea nui te rahi o te matūriki me te tohatoha o te rahi o te matūriki. Ka whakanuia e ngā matūriki angiangi te horahanga o te mata, ka whakanuia te tauhohenga matū me te matotoru o te paru. Ina whakawhāitihia te tohatoha rahi (arā, ka ōrite ake ngā matūriki), ka piki tere te matotoru, ka uaua te rere, ka piki ake te mōrearea o te taunga o te paipa. Ka taea e ngā tohatoha whānui (polydisperse), ina hangaia, te whakaiti i te matotoru kitea mā te whakapai ake i te pai o te tākai me te whakaiti i te waku i waenga i ngā matūriki. Hei tauira, ko ngā paru i hurihia kia rite ki te tauira Rosin-Rammler-Benne, i tātarihia rānei mā te āhuahanga fractal, e whakaatu ana i ngā rerekētanga nui o ngā āhuatanga rheological me te ātete kawe.
Ko te kukū totoka te mea e whakatau ana i te matotoru o ngā matūriki. Ko ngā kukū teitei ake ka whakanui ake i te matotoru āhua me te ahotea hua, ka neke ake te whanonga rere mai i te kirihou rūpahu (ngā kukū waenga) ki te kirihou Bingham, ki ngā tikanga whakawhanui kore-Newtonian rānei i ngā pito rawa. Ko te whanaungatanga i waenga i te kukū me te tohatoha rahi matūriki te mea nui mō te arotau i te kawe paru—mā te whakahaere i ēnei āhuatanga e rua ka taea te rere pai o te paipa mō te paru, ka whakaiti i te whakamahinga pūngao me te kakahu miihini.
Ko ngā āhuatanga ā-tinana pēnei i te matotoru me te mātotoru e whakatakoto ana i ngā tawhā mahi matua mō te whai huatanga o te kawe paipa. Ko te matotoru o te paru e whakatau ana i te ātete ki te rere, e pā tika ana ki ngā whakaritenga papu. Ko te matotoru o te paru, e pāngia ana e te kukū totoka me ngā āhuatanga matūriki, e hanga ana i te kōtaha pēhanga waipū, ā, e whakahaere ana i te pūmanawa mō te aukati me te taunga o ngā paipa. Ko ngā mita matotoru ipurangi, ngā mita matotoru wai ipurangi, me ngā tikanga tika mō te ine i te matotoru o te paru e hiahiatia ana mō te aroturukitanga wā-tūturu me te whakahaere tukanga, e tautoko ana i ngā tikanga ārai i te aukati me te taunga o ngā paipa.
Te Pānga o te Reorangi Parapara ki te Tukatuka
Ko ngā paru phosphate he āhua kore-Newtonian te nuinga. Kāore e pumau tonu te matotoru; e whakawhirinaki ana ki te tere o te kutikuti. Ko te nuinga e whakaatu ana i ngā āhuatanga hua-pseudoplastic (te angiangi kutikuti me te ahotea hua) me te kirihou Bingham rānei. I roto i ngā kupu mahi, ka tīmata te rere ina neke atu i te ahotea paepae (hua); ki tua atu i tēnei, ka tere te heke o te matotoru me te teitei ake o ngā tere kutikuti.
He pānga tika tō te āhua kore-Newtonian ki te pūnaha rere me te hoahoa pūnaha:
- Te hekenga o te pēhanga:Ko te matotoru me te ahotea hua ka whakanui ake i te hekenga pēhanga e hiahiatia ana mō tētahi tere kawe. Ko te tikanga he nui ake te pūngao e hiahiatia ana hei pupuri i te rere, inā koa i ngā tere iti iho, i ngā kukū totoka teitei rānei. Ko ngā tauira pāngarau pēnei i te ture Herschel-Bulkley, Bingham, Ostwald-Power rānei e whakamahia whānuitia ana hei matapae i tēnei whanonga me te whakamōhio i te rahi o te pūnaha.
- Te Whai Hua o te Paipa:Ina piki ake te matotoru me te ahotea hua ki tua atu i ētahi rohe (nā ngā panonitanga o te rahi matūriki, te kukū rānei), ka piki ake te mōrearea o te aukati rere, te aukati paipa, te taunga kino rānei. Te whakahaere whai hua o te rahi me te kukū o te matūriki, me te aroturukitanga o te matotoru me te mātotoru i te wā tūturu mā te whakamahi i ngā otinga mai ingā kaihanga mita mātotoru ipurangipērā i te Lonnmeter, he mea nui mō te mahi pono.
- Te Arotautanga o te Kawe:Mā te whanonga whakangāwari kutikuti (pseudoplastic) ka āwhina i te papu nā te mea ka heke te matotoru i ngā tere kutikuti teitei. Mā tēnei āhuatanga ka taea te whakaiti i te whakapaunga pūngao i te wā e kawe ana i ngā paipa āhua pumau, mena ka ōrite ngā tere kutikuti mahi ki ngā āhuatanga paru.
- Hoahoa Tauhohenga:I roto i te tango-pūkawa me te tango-pūkawa, ka pā te rheology kore-Newtonian ki te whakaranu i te tauhohenga, te whakawhiti papatipu, me te tohatoha wā noho. Ko te matotoru āhua me te ahotea hua ka whakahaere i te pūngao whakaranu e hiahiatia ana me te whai huatanga o ngā tauhohenga matū totoka-wai i roto i te tauhohenga.
Ko ngā hua mahi e whakawhirinaki ana ki te whakaahuatanga rheological tika. Ka whakamahia ngā taputapu pēnei i te rheometry hurihuri, ngā viscometer hurihuri, me ngā tauira CFD matatau hei hanga tauira rere tika. Ka manatokohia te whanonga e ngā whakamātautau paipa maha-porowhita taiwhanga me te ahumahi, ka ārahi i ngā kawa whakahaere hei whakaiti i te whakamahinga pūngao me te kakahu miihini. Ka tautokohia e ngā otinga ine wā-tūturu, pēnei i ngā mita matotoru ipurangi me te ine rahi o ngā matūriki i whakatārewatia, ngā rautaki whakahaere hihiri—e āwhina ana ki te aukati i ngā take pēnei i te taunga paru me te whakapai ake i te whai huatanga whānui o te kawe paru i roto i ngā paipa ahumahi.
Hei whakarāpopototanga, ko ngā āhuatanga o te paru phosphate—ina koa ko ērā e whakahaeretia ana mā te taunekeneke o ngā matūriki iri, te kukū, ngā tāpiringa, me te āhua wai—e tautuhi ana i te mahi kawe me te oranga o te tukanga. Ko te whakahaere i ngā matūriki iri i roto i te paru, te aroturuki i te tohatoha rahi o te matūriki, me te whakahaere i te kukū o ngā totoka he mea nui ki te whakapai ake i te rere o te paipa, te aukati i te taunga, me te arotau i te kawe paru mō ngā tukanga whakapai ake i te phosphate ahumahi.
Te Whakakorenga Whewhe me te Whakakorenga Phosphate me te Paraihe Phosphate
Ngā Mātāpono Tukanga
Te whakakorenga whanarikime ngā tukanga tango phosphorization e whakamahi ana i te paru phosphate e mahi ana i runga i ngā mātāpono o ngā tauhohenga mimiti wāhanga hau-wai-totoka i roto i ngā tauhohenga mākū.Te hauhā whanariki (SO₂)I roto i te hau para ahumahi, ka rewa tuatahi te hau ki roto i te wāhanga wai o te para phosphate. I reira, ka tere te tauhohe ki ngā katote phosphate me te wai, ka hanga he waikawa phosphoric me ngā hua totoka, me te whakahohe hoki i te whakaora o te phosphorus. Ko ngā tikanga mimiti e tohuhia ana e ngā huringa ā-taahiraa: ka horapa te SO₂ ā-hau puta noa i ngā mata maturuturu, ka tomo ki te para, kātahi ka puritia mā te matū. Ka puta pea te tangohanga konupora mai i te para, i runga i te taiao matū motuhake me ngā tere whakawhiti papatipu. Ko te mana whakahaere matua mō te tere mimiti ka tukuna e te ātete kiriata hau i te atanga, ka mea he mea nui te turbulence me te ranunga mō te whai huatanga nui.
Ko te taunekeneke o ngā tukanga ā-tinana i roto i te tauhohenga te mea nui ki te hua o te tukanga. Ko ngā pata paru e iri ana i roto i te awa hau ka whakanui ake i te horahanga ā-mata mō te pa atu me te mimiti o te SO₂, me ngā tere whakawhiti papatipu hau-wai e whakahaerehia ana e te rahi o te pata, te tere paheke, ngā taumata turbulence, me te pāmahana. Ko te whakawhiti papatipu whai hua e whakawhirinaki ana ki te marara ā-tinana o ngā pata me te tere o ā rātou tauhohenga ki te SO₂. Ko te taunekeneke pai ake o te pata-hau ehara i te mea ka whakanui ake i te tango SO₂ engari ka tautoko hoki i te whakaora phosphate whai hua, he mea nui mō te whakahaere parahanga whakauru me te hangarua rauemi.
Ngā Take e Pā Ana ki te Whai Hua o te Tauhohenga
Ko te āhua o te tauhohenga te mea matua e whakatau ana i te pai o te mimiti. Ko ngā āhuatanga motuhake pēnei i te koki me te diameter o te urunga ka whakahaere i te huarahi e uru ai te hau me te paru ki roto i te tauhohenga me te whakaranu. Hei tauira, ko ngā koki me ngā diameter iti o te urunga ka whakatairanga i te nekenekehanga teitei ake me te pai ake o te marara o ngā pata, ka whakanui ake i te whakawhiti papatipu me te whakanui ake i te hopu SO₂. Ko ngā diameter nui ake ka whakaiti i te pai o te mahi mā te whakawaiwai i te nekenekehanga me te whakaiti i te wā pa i waenga i te hau me ngā pata paru. He rerekē ki te whakaaro noa, ko te tāpiri i ngā ārai o roto he iti noa te pānga ki ngā tere tango whanariki ki te whakataurite ki ngā pānga nui o te hoahoa urunga me te āhua whānui.
Ko ngā āhuatanga ā-tinana o te para phosphate tonu—ina koa ko te matotoru, te mātotoru, me te tohatoha rahi o te matūriki—he pānga nui ki te kaha o te tauhohenga. Ko te matotoru nui o te para ka whakaiti i te nekehanga o te pata, ka aukati i te tukanga whakaranu me te tukanga mimiti. I tetahi atu taha, ko te matotoru iti ka whakapai ake i te pai o te rere engari ka piki ake pea te taunga matūriki me te mōrearea o te tauine ā-rohe. Ka pāngia te pumau o te whakatārewatanga o te pata me ngā ia taunga e ngā rerekētanga matotoru; ko ngā para he tika te matotoru ka pai ake te ātete ki te taunga, ka mau tonu te pa pai mō te mimiti.
He pānga tika anō hoki te tohatoha rahi o te matūriki ki te mahi mimiti. Ko ngā matūriki angiangi ka nui ake te horahanga o te mata, ka whakanui ake i te whakawhiti papatipu SO₂, ko ngā matūriki tino matotoru, kāore rānei i te tino tohatoha ka whakatairanga i te tere o te taunga, te tauine ā-rohe, me te aukati. He mea nui te whakatārewatanga auau o ngā matūriki hei karo i ēnei take. Te ine me te whakahaere i ēnei āhuatanga—mā te whakamahi ingā mita matotoru paru ipurangi, ngā mita mātotoru wai ipurangi, me ngā taputapu mai i ngā kaihanga mita mātotoru ipurangi motuhake—he mahi paerewa mō ngā tipu hou.
Mā te whakatārewatanga me te mararatanga whai hua o ngā matūriki totoka i roto i te paru ka ārai i ngā ia o te tauine ā-rohe me te poke o te tauhohenga. Mā te pupuri i te aueuetanga kia ranea hei pupuri i ngā matūriki kia iri, me te aroturuki me te whakarerekē i te matotoru, ka āwhina i te aukati i te whakatakotoranga o ngā totoka ki runga i ngā roto me ngā paipa o te tauhohenga. He mea nui ngā hangarau pēnei i ngā mita ipurangi a Lonnmeter mō te ine matotoru me te mātotoru i te wā tūturu, e āhei ai te whakahaere matatau i ngā āhuatanga paru me te arotau tonu i te mahi tango-pūkawa me te tango-pūkawa.
Te Whakaiti i ngā Mōrearea Tauine me te Ārai
Ko te ārai i te tauine me te aukati i roto i ngā tauhohenga paru phosphate e whakawhirinaki ana ki ngā āhuatanga paru pai me te hoahoa tauhohenga kua ata hangaia. Mā te mahi i te matotoru kua whakahaeretia me te pupuri i te tohatoha rahi matūriki tika ka whakaiti i te tūponotanga o te taunga matūriki, ā, ka taea ai te whakatārewatanga ōrite. Ko ngā āhua o te tauhohenga kua hangaia mō te aueue nui—ina koa i ngā tomokanga hau me te paru—ka whakatairanga i te marara tonu o ngā matūriki, ka ārai i ngā rohe iti te rere ka puta pea te taunga me te hanganga tauine.
E whakaatu ana ngā rautaki mahi i ahu mai i ngā rangahau take ahumahi me ngā rangahau whakatauira tata nei, ko te whirihora i ngā tomokanga tauhohenga mō te aueue kaha, ōrite, me te whakamahi i ngā kukū paru i roto i ngā matapihi kua tūtohutia ka whakaiti i te mōrearea tauine. He tino whai hua te karo i ngā taumata matotoru teitei me te aukati i ngā kawenga totoka nui rawa atu mō te aukati i te aukati i ngā paipa me te arotau i te kawe paru. Hei tāpiri, mā te whakatinana i ngā huringa paru matao ka taea te whakarei ake i te hopu matūriki pai, te whakaiti i te paru mā te whakanui ake i te haukū o te kohu me te whakatairanga i te tango i ngā matūriki iti-micrometer.
Ka tautokona anō te whakahaere i te tauine e ngā rautaki matū: ko te ine tika o ngā antiscalants—ina koa ko ngā whakatakotoranga kua tohua mō ngā pūnaha phosphate-nui—ka whakawhāiti i te whakatakotoranga o te tauine phosphate konupūmā me te kore e hiahiatia he ine waikawa kaha, he whakarerekētanga nui rānei i te pūnaha. Ko te whiriwhiri me te whakarerekētanga o ēnei kaihoko e whakawhirinaki ana ki te aroturuki ipurangi o te matū wai me te paru, kia mau tonu ai te tiakitanga mai i te tauine i roto i ngā āhuatanga whakahaere wā-tūturu.
Mā te arotau i ēnei mana whakahaere ā-tinana me te matū ka whakarei ake i te pai o te kawe i ngā paipa, ka whakapai ake i te pai o te rere o te paru i roto i ngā paipa, ā, ka tautoko i te mahi roa tonu o te tauhohenga me te kore e whakararuraru i ngā mahi e puta mai ana i te aukati me te taunga. Ko ngā inenga tika o te matotoru o te paru, te mātotoru, me te rahi o te matūriki i whakatārewatia—e tautokona ana e ngā mita ipurangi pai rawa atu—he mea nui ki te whakatutuki i ēnei hua me te pupuri i ngā tukanga tango-pūkawa me te tango-pūkawa teitei i roto i ngā pūnaha whakahaere paru phosphate.
Te Whakanui i te Whai Huatanga o te Kawe Paipa mō te Parai Phosphate
Ngā Aromatawai Rere i roto i te Kawe Paipa
Ko te whai huatanga o te kawe i te paru phosphate e whakawhirinaki ana ki ngā āhuatanga matua e whā: te tere, te matotoru, te mātotoru, me ngā āhuatanga o ngā matūriki iri. Ko te tere o te paru te mea e whakatau tika ana i te mōrearea o te whakatakotoranga—ko ngā tere teitei ake ka pupuri i ngā totoka iri, ka whakaiti i ngā tūponotanga aukati, engari ka piki ake hoki ngā hiahia pūngao me ngā utu whakahaere. He paepae tere nui kei raro iho ka tīmata te tau o ngā matūriki, ka whakawehi i te rere pai me te hauora o ngā paipa.
Ko te matotoru, e pā tata ana ki te kukū me te pāmahana o te paru, ka pā ki te whanonga o te wai hei mono, hei whai rānei i te rere pōrearea. He maha ngā wā ka whakaatuhia e ngā paru phosphate ngā āhuatanga kore-Newtonian, pseudoplastic, Bingham kirihou rānei, ka piki ake te matotoru i te pikinga o te ihirangi totoka. He mea nui te ine tika i te matotoru o te paru mā te whakamahi i ngā mita matotoru ipurangi, i ngā pūnaha motuhake rānei, pērā i ngā mita matotoru ipurangi pai rawa atu mō te paru, hei pupuri i te pumau o te kawe me te matapae i ngā whakarerekētanga mahi.
Ko te mātotoru o te paru, he mahi a te kukū o ngā totoka i whakatārewatia, ka whakarerekē i te hekenga pēhanga i te taha o te paipa, ka pā ki te whakamahinga pūngao me te pumau o te kawe. Ki te kore e aroturukitia ngā piki me ngā heke o te mātotoru, ka hua ake he nekehanga o te tikanga rere me te whakanui ake i te mōrearea o te whakatakotoranga. Ka whakaratohia e ngā mita mātotoru wai ipurangi, tae atu ki ērā a ngā kaihanga mita mātotoru ipurangi matua, he māramatanga mātotoru wā-tūturu, hei āwhina i te pupuri i te taurite o te pūnaha.
He mea nui anō hoki te rahi me te tohatoha o ngā matūriki e iri ana. Mā ngā matūriki nui ake, ngā tohatoha whānui rānei o ngā matūriki ka nui ake te tūponotanga o te taunga, inā koa i ngā wāhanga he iti te tere, he rerekē rānei te diameter o te paipa. Mā ngā pūnaha ine rahi o ngā matūriki e iri ana ka noho tonu ngā tohatoha rahi o ngā matūriki i roto i ngā awhe mahi haumaru, ka tautoko i te whakahaere whai hua o ngā matūriki iri i roto i te paru me te whakaiti i ngā tūponotanga taunga.
Ka pāngia te pumau o te rere me te pai o te kawe e ngā tawhā hoahoa paipa—te whānui, te taratara o roto, me te huarahi whānui. Ka whakaitihia te tere i tētahi tere rere e te whakanui ake i te whānui o te paipa, ka piki ake te mōrearea taunga mēnā kāore e utua ki ngā tere papu teitei ake. Ka whakatairangahia te taratara o roto, te piko koi rānei, e āwhina ana i te whakatārewatanga ā-rohe engari ka taea hoki te whakatairanga i te hanganga o ngā porowhita me te taunga ā-rohe, ka piki ake te hiahia pūngao me ngā matea tiaki.
Te Ārai i te Taunga Para me te Ārai i ngā Paipa
Ka puta te taunga paru me te aukati i ngā paipa ina heke te tere o te wai i raro i te paepae whakatārewatanga o ngā totoka. Ka hua ake tēnei i te taunga ā-papa o ngā totoka ki te raro o te paipa, ka hangaia he moenga tūmau, he putunga rānei e aukati ana, e aukati ana rānei i te rere. Ka taea e te kohikohinga matūriki—ina huihui ngā totoka pai nā ngā taunekeneke hiko, matū rānei—te whakatere i te taunga, inā koa kei roto ngā tāpiringa matū, te nui rānei o te dolomite.
Ko ngā tikanga whakahiato me te taunga ehara i te mea ko te tere anake, engari ko te rahi, te āhua, me te mātotoru o ngā matūriki. Ko ngā paru paru whai uku, ngā paru matūriki pai rānei, he ngawari ake ki te taunga "rite ki te tiēre", engari ko ngā paru he maha ngā taupori matūriki kua whakaranua, kua nui ake rānei, ka tau koretake pea, ka hanga paparanga i te taha o te paipa. Ka taea hoki e ngā whakahekenga ā-rohe te whakanui ake i te matotoru o te paru, ka akiaki i te purunga, inā koa i ngā piko o ngā paipa, i ngā takirere rānei.
E whakaatu ana ngā tātaritanga aro o nāianei mā te whakamahi i te pōrohe whānui o te haukoti, ko te tere me te rahi o te matūriki ngā mea matua e whakatau ana i te mahi taunga me te kawe. Me aroturuki tonu ēnei āhuatanga, me te whakahaere hihiri hoki kia kaha ai te mahi paipa. Mā ngā taputapu ā-roto—pērā i ngā mita matotoru ipurangi me ngā tātaritanga rahi matūriki ā-roto—ka whakaratohia he raraunga mahi mō ngā whakatikatika mahi, pērā i te whakanui ake i te tere o te papu, te horopeta rānei i ngā kaihoko whakamarara ina kitea ngā au kino.
Kua whakawhanakehia ngā mahi auaha tae atu ki ngā paninga paipa matatau hei whakaiti i te piri me te whakaiti i ngā rohe ka taea e ngā matūriki te tau, hei whakapakari i ngā rautaki ārai i te aukati i ngā paipa. Me whai whakaaro hoki te whakatakotoranga o ngā paipa me ngā wā mahi ki ngā wā o te whakahekenga o te rere, nā te mea ahakoa ngā wā poto i raro i ngā paepae tere matua ka taea te tīmata i te hanganga tere o te moenga.
Ngā Huarahi Tātari me te Rorohiko mō te Arotau Rere
Ko te arotau i te rere o te paru phosphate me mārama me te whakahaere tika i ngā tawhā maha, e whakawhirinaki ana tetahi ki tetahi i raro i ngā āhuatanga o te ao tūturu kāore i te tino mārama. Ko te tātari aro o te ao (GSA) mā te whakamahi i ngā whakawhānuitanga porowhita (PCE) kua puta hei tikanga matua mō te ine i te pānga o ngā āwangawanga o ngā taurangi whakauru—pērā i te mineralogy o te konganuku, te rahi o te matūriki, ngā āhuatanga paru ā-wā rānei—ki ngā inenga kawe matua pērā i te hekenga pēhanga, te tere, me te mōrearea o te taunga.
E whakaatu ana te GSA, puta noa i te whānuitanga o ngā hanganga paru phosphate me ngā whirihoranga tukanga, ko ngā rerekētanga tere me te rahi o te matūriki te mea tino pānga; nō reira, me aro nui te arotahi ki te whakahaere i tā rātou aromatawai me te whakahaere. He mea nui tonu te mātotoru me te matotoru mō ngā tataunga rohe, hei āwhina i ngā kaiwhakahaere ki te whakatakoto i ngā matapihi whakahaere mō te rere haumaru, whai hua.
Mā te whakatauira rorohiko, inā koa me te wehewehenga orthogonal tika me te whakatauira whakakapi e hangai ana ki te PCE, ka taea te whakatauira horopaki me te arotau whai hua. Ka tāruatia e ēnei tauira raupapa-iti ngā āhuatanga matua o ngā whakatauira CFD taumira teitei me te hurihanga poto, e tautoko ana i te whakatau tere mō ngā whakarerekētanga tukanga me te hoahoa paipa.
Ka whakamanahia ēnei huarahi tātari ki ngā raraunga o te ao tūturu: ka whakauruhia ngā inenga ā-papa o te tere rere, te ngaronga o te upoko, me ngā huihuinga whakatakotoranga ki roto i ngā huringa whakatikatika tauira me te whakapai tonu. Mā te hono i ngā pūoko matatau (pēnei i ngā tātari matotoru me te kiato ipurangi a Lonnmeter) me te whakatauira hihiri, ka taea e ngā kaiwhakahaere te whakatinana i ngā rautaki arotau rere paru e arotau ana ki ngā huringa o te taumata o te konganuku, te tohatoha rahi matūriki, me ngā āhuatanga taiao.

Te Hiranga o te Aroturukitanga o ngā Taonga Para i te Wā Tuturu
Tika,te ine tonu i te mātotorumematotoruHe mea nui te pūnaha nei mō te kawe pai o te paru phosphate me te tango i te whanariki me te tango i te phosphorus. Mā te aroturukitanga wā-tūturu ka taea te whakarerekē tonu i ngā tawhā tukanga hei whakautu ki ngā āhuatanga paru e huri haere ana. Mā tēnei whakahaere tukanga matatau ka whakaitihia te wā kore mahi i whakaritea e puta mai ana i te taunga me te aukati i ngā paipa—ngā take noa i roto i ngā paipa paru phosphate.
Mā ngā raraunga tonu mō te matotoru me te matotoru o te paru ka āwhina i ngā kaiwhakahaere ki te kite wawe i ngā rerekētanga e tohu ana i te pikinga o te mōrearea o te taunga, te aukati rānei o ngā matūriki. Hei tauira, ki te kitea he pikinga o te matotoru, te matotoru rānei, ka taea te whakarerekē i ngā tere rere, te whakapai ake rānei i te horopeta matū hei whakaora i te kawe paipa whai hua.
