Ukuyila ipulp kubalulekile ngaphambi kokwenza iphepha, nto leyo eshiya impembelelo enkulu ekusebenzeni okuqhelekileyo komatshini wephepha kunye nomgangatho wephepha. Izinto eziphambili ekubetheni yingxinano yepulp, inqanaba lokubetha, kunye nomlinganiselo wepulp.
Ukulinganisa Uxinzelelo lwePulp
Uxinzelelo lwepulp olungazinzanga lunokubangela ukuba umgangatho wephepha ungalingani, kwaye lunokubangela ukuqhekeka kwephepha kwaye luphazamise ukwenziwa kwephepha okuqhelekileyo kube kubi nangakumbi. Izinto ezibangela ukungazinzi koxinzelelo lwepulp zixhomekeke ekutshintsheni koxinzelelo lwepulp eluhlaza kunye nezinto ezilahliweyo, ukulungiswa koxinzelelo ngesandla ekubetheni, ekugxileni nasekuxubeni, kunye nenkqubo yamanzi amhlophe engalinganiyo.
Utshintsho kwi-Raw Pulp Concentration
I-pulp ephuma kwindawo yokusebenzela yokukhupha i-pulping iyahluka ngokwezinga loxinzelelo. Uxinzelelo lokugqibela lwe-pulp luya kuchaphazeleka ukuba akukho hlengahlengiso lufunekayo olwenziweyo ekugxileni.
Uhlengahlengiso lokugxila ekubetheni
Ngexesha lokubethwa, i-pulp idlula kwiinkqubo ezifana nokugxininisa, ukubethelwa, kunye nokuxuba, nto leyo efuna ukulungiswa koxinzelelo. Ezinye iinkqubo zisebenzisapulp di-ensitymi-eter, kodwa uhlengahlengiso olwenziwe ngesandla luqheleke kakhulu. Utshintsho lokugxila lunokwenzeka ngenxa yokungabi namava omqhubi, ukungabikho kwenkuthalo, okanye ukungasebenzi kakuhle kwezixhobo.
Iinguqu kwiWai-ste StuffUkugxila
Iphepha eliqhekekileyo eliphinda lisetyenziswe liyanqunyulwa kwi-hydropulper lize lixutywe ukuya kwinqanaba elizinzileyo ngaphambi kokuba lixutywe ukuya kwinqanaba elifunekayo lenkqubo. Ukuba uxinano lwezinto ezilahliweyo luyahluka kakhulu ngexesha lokuphelelwa ngamanzi emzimbeni kunye nokuxutywa, lunokuphazamisa inkqubo ye-pulp iyonke.
Ukungazinzi kwiinkqubo zamanzi amhlophe
Amanzi amhlophe asetyenziswa kwakhona ekuxutyweni kwe-pulp ukunciphisa ukusetyenziswa kwamanzi kunye nokulahleka kwefayibha. Ukuba inkqubo yamanzi amhlophe ayilingani okanye uxinzelelo kunye nokuhamba kwayo azizinzanga, kuya kuchaphazela ukuxutywa kwe-pulp kunye noxinzelelo.
Isidanga sokuBetha
Izinto ezininzi zichaphazela ukubetheka kwepulp, ezinje ngoxinzelelo, ugxininiso, isantya sokuhamba, ixesha, ubushushu, imeko yeblade, kunye nobuchule bokusebenzisa. Ukuba naliphi na inyathelo aliphathwanga kakuhle, umgangatho wokubetheka kwepulp uya kuphazamiseka. Ukuzinzisa ukubetheka kunzima ngaphandle kokujonga rhoqo, kodwa kubalulekile ekwenzeni iphepha elizinzileyo.
1. Iziphumo zeDigri yokubetha ephantsi
Xa ukubetheka kuphantsi kakhulu, iindonga eziphambili nezesibini zemicu aziqhekeki ngokwaneleyo. Ukudumba kwefayibha, ukusika, ifibrillation, kunye nokwakheka kwefines akuhlangabezani neemfuno zenkqubo.
Oku kubangela ukuba amanzi aphume ngokukhawuleza kakhulu ngexesha lokwakheka, ukubophana kwefayibha okungahambi kakuhle, kunye nokwakheka kwamaphepha okungalingani, okuchaphazela ukufana, amandla, kunye nokuguda.
2. Iziphumo zeDigri yokubetha kakhulu
Ukubetha okwandileyo kuphucula amandla okubopha kodwa kunciphisa ubude obuqhelekileyo befayibha kunye nobunzima bewebhu emanzi.
Ukubetheka kakhulu kukhawulezisa ukusika ifayibha, ukudumba, kunye nokufibrilla, okwenza ukutsalwa kwamanzi kwintambo kube nzima ngakumbi, kwandise umda wamanzi, kwaye kwandise umthamo womswakama kwiwebhu emanzi.
Ukufuma okugqithisileyo kunokubangela ukugquma okanye ukuqhekeka okuninzi ngenxa yoxinzelelo olunganeleyo lokucinezela.
Ukubetheka kakhulu kwandisa ukoma, nto leyo ekhokelela kutshintsho kwimilinganiselo yesantya kumacandelo oomatshini, nto leyo echaphazela ubukhulu bamaphepha, kwaye inciphisa amandla kunye nozinzo.
Umlinganiselo wePulp
Umlinganiselo we-pulp uxhomekeke kwizinto ezifana neempawu zezinto eziluhlaza, indlela yokukhupha i-pulp, ukusebenza komatshini, kunye nohlobo lwephepha kunye neemfuno zomgangatho. Emva kokumisela iimeko zomlinganiselo, ukunamathela ngokungqongqo kwinkqubo kubalulekile ukuthintela ukuphazamiseka kwemveliso kunye nokunyuka kweendleko.
Umlinganiselo weFiber omde kunye nomfutshane
Umlinganiselo ofanelekileyo uphucula ukubopha kwefayibha, ukufana kweshiti, kunye namandla ngelixa kunciphisa iindleko kunye nokuphucula ukusebenza kakuhle.
Ifayibha encinci kakhulu inciphisa amandla okubopha kunye namandla ephepha elimanzi, nto leyo ebangela ukuqhekeka, ngelixa ifayibha ende kakhulu ingenakwenzeka ngokwezoqoqosho.
Izinto ezikhethekileyo ekufuneka ziqwalaselwe
I-pulp yengca yekhemikhali, enemicu emifutshane, iindonga zeseli ezixineneyo, kunye nomxholo ophezulu we-hemicellulose, yenza kube nzima ukwenza iphepha kwaye ichaphazele umgangatho. Ukunciphisa ezi ngxaki, izinto zefayibha ende ezikumgangatho ophezulu, ezifana nomqhaphu, umthi, okanye i-pulp yeflakisi, zinokuxutywa, nangona zibiza kakhulu. Ukudibanisa ngokufanelekileyo imicu emide nemifutshane kubalulekile ekuqinisekiseni ukwenziwa kwephepha okugudileyo, ukuhlangabezana nemigangatho yomgangatho, kunye nokufezekisa ukusebenza kakuhle kweendleko.
