Izincamathelisi kunye nezitywini zihlobene kakhulu xa kubhekiselwa ekuncamathiseleni okanye ekudibaniseni iindawo ezimbini okanye ngaphezulu. Zombini zizinto ezincamathelisiweyo ezisetyenziswa kwiikhemikhali ukuze zenze ikhonkco eliqinileyo kumphezulu ezisetyenziswa kuwo.
Izinto zokuncamathelisa zendalo kunye nezinto zokutywina ziyafumaneka kwindawo esikuyo kwasekuqaleni. Zombini zisetyenziswa apha naphaya, ukusuka kwiindawo zokusebenzela zasekhaya ukuya kwizinto ezintsha zobuchwepheshe. Umzekelo, ukupakisha, ukuvelisa amaphepha, ukuvelisa iinqwelomoya, i-aerospace, izihlangu, izixhobo zemoto kunye neze-elektroniki zonke ziinkampani ezifuna izinto zokuncamathelisa kunye nezinto zokutywina.
Uthelekiso Phakathi Kwezinto Zokuncamathelisa Nezitywina
La magama mabini afana kwaye anokutshintshwa kwiimeko ezithile, kodwa kusekho umahluko phakathi kwawo ngokwenjongo kunye nokusetyenziswa kokugqibela. I-Adhesive luhlobo lwento esetyenziselwa ukubamba iindawo ezimbini ngendlela eqinileyo nehlala ihleli ngelixa i-sealant yinto esetyenziselwa ukunamathelisa iindawo ezimbini okanye ngaphezulu.
Eyokuqala iluncedo xa kufuneka umanyano oluhlala ixesha elide noluqinileyo; eyesibini isetyenziselwa ukuthintela ukuvuza kolwelo okanye igesi kwindawo yokuqala ngenjongo yexeshana. Amandla ebhondi yesitywina ayibuthathaka ngokwemvelo kunaleyo yeglue, njengoko ukusebenza kwayo kuxhomekeke kuhlobo oluthile kunye nokusetyenziswa okucetywayo, kubandakanya amandla ezimelana nawo kunye neempawu zazo zobushushu.
Izinto zokuncamathelisa kunye nezitywini zabelana ngeempawu eziphambili zokuziphatha ezivumela ukubopha okusebenzayo:
-
Ukunyibilika: Zombini mazibonakalise ukuziphatha okufana nolwelo ngexesha lokusetyenziswa ukuqinisekisa ukudibana okufanelekileyo nomphezulu okanye izinto ezingaphantsi komhlaba, zizalise ngempumelelo naziphi na izikhewu.
-
Ukuqina: Zombini ziyaqina zibe yimeko eqinileyo okanye eyomeleleyo ukuze zixhase kwaye zimelane nemithwalo eyahlukeneyo efakwa kwibhondi.
Ukuqina kwezinto zokuncamathelisa kunye nezitywina
Izincamathelisi zihlulwe zibe zizincamathelisi zendalo kunye nezincamathelisi ezenziweyo ngokwemvelaphi yazo. Ukuqina kuthathwa njengokumelana nolwelo okanye ukuhamba kwamanzi. Izincamathelisi ezixineneyo kunye nezitywini ziincindi ezingezizo ezeNewtonian. Ngamanye amazwi, ukufundwa kwe-viscosity kuxhomekeke kwisantya sokucheba esilinganisiweyo.
Ukuqina kudlala indima ebalulekileyo ekuvelisweni nasekusetyenzisweni kwezinto zokuncamathelisa, kusebenza njengophawu oluphambili lweempawu ezinje ngoxinano, uzinzo, umxholo we-solvent, izinga lokuxuba, ubunzima beemolekyuli, kunye nokuhambelana ngokubanzi okanye ukusasazwa kobukhulu beesuntswana.
Ukuqina kwee-adhesive kuyahluka kakhulu ngokusekelwe kwindlela ezicetywayo ukuyisebenzisa, njengokuvala okanye ukubopha. Ii-adhesives zahlulwe zibe ziintlobo ze-viscosity ephantsi, ephakathi, kunye ne-viscosity ephezulu, nganye ifanelekile kwiimeko ezithile zokusetyenziswa:
-
Izincamathelisi eziphantsi zeViscosity: Ilungele ukugqunywa, ukugalelwa embizeni, kunye nokufunxwa ngenxa yokuba iyakwazi ukuhamba ngokulula kwaye izalise iindawo ezincinci.
-
Izincamathelisi zokuncamathelisa eziphakathi: Isetyenziswa rhoqo ekubopheni nasekuvaleni, inika ulungelelwaniso lokuhamba kunye nolawulo.
-
Izincamathelisi eziQinisekayo eziphezulu: Yenzelwe ukusetyenziswa okungathontsiziyo okanye okungagungqiyo, njengee-epoxies ezithile, apho ukuqina kwesakhiwo kubalulekile.
Iindlela zokulinganisa i-viscosity zemveli zixhomekeke kwisampuli eyenziwe ngesandla kunye nohlalutyo lwelebhu, ezithatha ixesha kwaye zifuna umsebenzi omninzi. Ezi ndlela azifanelekanga kulawulo lwenkqubo ngexesha langempela, njengoko iipropati ezilinganiswe kwilebhu zisenokungabonisi ngokuchanekileyo indlela i-adhesive esebenza ngayo kumgca wemveliso ngenxa yezinto ezifana nexesha elidlulileyo, ukubola kwe-sedimentation, okanye ukuguga kolwelo.
ILonnmeterimitha ye-viscosity emgceniIbonelela ngesisombululo esiphambili sokulawula i-viscosity ngexesha langempela, ijongana nemida yeendlela zemveli kunye nokuphucula iinkqubo zokwenza i-glue. Ihlangabezana nale ntlobo ngeentlobo ngoluhlu olubanzi lokulinganisa (0.5 cP ukuya kwi-50,000 cP) kunye neemilo ze-sensor ezinokwenziwa ngokwezifiso, okwenza ukuba ihambelane neefomyula ezahlukeneyo ze-glue, ukusuka kwi-cyanoacrylates ezi-viscosity ezisezantsi ukuya kwi-epoxy resins ezi-viscosity eziphezulu. Amandla ayo okudibanisa kwiipayipi, iitanki, okanye ii-reactors ezineendlela zokufaka eziguquguqukayo (umz., i-DN100 flange, ubunzulu bokufaka ukusuka kwi-500mm ukuya kwi-4000mm) iqinisekisa ukuguquguquka kuzo zonke iindlela ezahlukeneyo zokuseta imveliso.
Ukubaluleka kokujonga ukuxinana kunye noxinano
Imveliso yokuncamathelisa ibandakanya ukuxuba okanye ukusasaza izinto ezahlukeneyo ukuze kufezekiswe iipropati ezithile, kubandakanya ukumelana neekhemikhali, ukuzinza kobushushu, ukumelana nokutsha, ulawulo lokushwabana, ukuguquguquka, ukusebenza kakuhle, kunye namandla kwimveliso yokugqibela.
I-Lonnmeter inline viscometer yenzelwe ukusetyenziswa kwiindawo ezahlukeneyo zokulinganisa izinto zokuncamathelisa, iiglu, okanye iinkqubo zokuvelisa istatshi. Ivumela ukujonga i-viscosity ngaphakathi kunye neeparameters eziphuma kuyo ezifana noxinano kunye nobushushu. Ukufakelwa kungenziwa ngokuthe ngqo kwitanki yokuxuba ukuqonda ukuguquka kwe-viscosity kunye nokumisela ukuba ukuxuba okufunekayo kufikelelwe nini; kwiitanki zokugcina ukuqinisekisa ukuba iimpawu zolwelo zigcinwa; okanye kwimibhobho, njengoko ulwelo luhamba phakathi kweeyunithi.
Ukufakelwa kweeMitha zeViscosity kunye neDensity
KwiiTanki
Ukulinganisa i-viscosity ngaphakathi kwitanki yokuxuba ulwelo olunamathelayo kwenza ukuba kube nohlengahlengiso olukhawulezileyo ukuqinisekisa ukuba iipropati zolwelo zihlala zifana, nto leyo ekhokelela ekwandeni kokusebenza kakuhle kwemveliso kunye nokunciphisa inkunkuma yezixhobo.
Imitha yokulinganisa i-viscosity ingafakwa kwi-mixing tank. Iimitha zobuninzi kunye ne-viscosity azikhuthazwa ukuba zifakwe ngqo kwi-mixing tanks, njengoko isenzo sokuxuba sinokuzisa ingxolo echaphazela ukuchaneka kokulinganisa. Nangona kunjalo, ukuba itanki ibandakanya umgca wepompo yokujikeleza kwakhona, imitha yobuninzi kunye ne-viscosity ingafakwa ngokufanelekileyo kwipayipi, njengoko kuchaziwe kwicandelo elilandelayo.
Ukuze bafumane isikhokelo sokufakela esilungiselelwe wena, abathengi kufuneka baqhagamshelane neqela lenkxaso baze banike imizobo okanye imifanekiso yetanki, bechaza amazibuko akhoyo kunye neemeko zokusebenza ezifana nobushushu, uxinzelelo, kunye nokuqina okulindelekileyo.
Kwimibhobho
Indawo efanelekileyo yokufaka iimitha ze-viscosity kunye ne-density kwimibhobho ye-adhesive fluid kukwingqiniba, kusetyenziswa i-axial setup apho i-probe sensing element ijongene nokuhamba kolwelo. Oku kudla ngokufuna i-probe ende yokufaka, enokwenziwa ngokwezifiso zobude bokufaka kunye noqhagamshelo lwenkqubo ngokusekelwe kubukhulu kunye neemfuno zombhobho.
Ubude bokufakwa kufuneka buqinisekise ukuba into yokuva inxibelelana ngokupheleleyo nolwelo oluhambayo, kuthintelwe iindawo ezifileyo okanye ezimileyo kufutshane nezibuko lokufakelwa. Ukubeka into yokuva kwindawo ethe tye kunceda ukuyigcina icocekile, njengoko ulwelo luhamba phezu koyilo olucwangcisiweyo lweprobe, nto leyo ephucula ukuchaneka kokulinganisa kunye nokuthembeka.
