Imikhiqizo yeVitamin yonke itholakala kwi-pulp yekotoni yemvelo noma ipulpiti lezinkuni, elikhiqizwa ngokuthezeka. Imikhiqizo ehlukene ye-cellulose Sebenzisa ama-ejenti ahlukile aphenyazayo. Umenzeli othembela eHydroxyyethyl cellulose (Hec) yi-ethylene oxide, futhi umenzeli othembela e-hydroxypropyllylylth methylcellulose (HPMC) yizo ezinye izinhlobo zama-ejenti aphenyazayo. (chloromethane ne-propelene oxide).
Ngopende wangempela we-szone kanye nopende we-latex, i-hydroxyethyl cellulose ingasetshenziswa njengomuntu omkhulu.
Upende wamatshe wangempela kulula ukucasuka ngenxa yenani laso elikhulu lokucaciswa okuhlanganisiwe nokucaciswa okukhulu. Kuyadingeka ukwengeza umkhulu ukwandisa ukubonakala kwayo ukuze uhlangabezane nokubona okudingekayo ukuze ufafazwe ngesikhathi sokwakha, ukuthuthukisa ukuqina kwawo kokugcina, futhi uzuze amandla athile.
Uma ufuna upende wamatshe wangempela ukufezekisa amandla amahle, ukumelana kwamanzi okuhle nokumelana nesimo sezulu, ukukhethwa kwezinto zokwakha kanye nokwakhiwa kwefomula kubaluleke kakhulu.
Ngaphansi kwezimo ezijwayelekile, inani le-emulsion elisetshenziswa kupende lwamatshe aphezulu angempela lizoba liphezulu.
Isibonelo, ethani lamatshe abungelwa itshe, kungahle kube nama-300kg we-acrylic emsulwa emsulwa kanye ne-650kg yesihlabathi samatshe esinemibala emvelo. Lapho okuqukethwe okuqinile kwe-emulsion kungu-50%, umthamo we-300kg we-emulsion ngemuva kokomiswa cishe kwamalitha ayi-150, futhi umthamo we-650kg wesihlabathi cishe ma-228 amalitha. Lokho kusho ukuthi, i-PVC (ivolumu ye-Pigment Voluvortion) yopende wamatshe wangempela ingama-60% ngalesi sikhathi, ngoba izinhlayiya zesihlabathi ezinemibala zikhulu futhi zingaphansi kwesimo sokusatshalaliswa okuthile, okusomile Upende wamatshe wangempela kungenzeka ube ku-CPVC (okuhlushwa okubucayi). Ukuhlushwa kwevolumu ye-pigment) i-approx. Ngokuya ngokuthi umkhulu ukhathazekile, uma ukhetha i-cellulose nge-viscosity efanelekile, upende wamatshe wangempela ungakha ifilimu ephelele futhi ebumnyene yokupenda ukuze uhlangabezane nezidingo ezintathu zokusebenza zamatshe eziwupende. Uma okuqukethwe kwe-Emulsion ye-Real Stone Paint emulsion kuphansi, kunconywa ukusebenzisa i-cellulose enokubonakala okuphezulu njengomuntu omkhulu (njengokuqagela okungu-100,000), ikakhulukazi ngemuva kwentengo ye-cellulose esetshenzisiwe nokwenza Itshe langempela ukusebenza kopende kungcono.
Abanye abakhiqizi bezinkomo bangempela bezomnotho basebenzisa i-hydroxypropylllylylym methylcellulose esikhundleni se-hydroxyethyl cellulose yezindleko nezinye izinto.
Uma kuqhathaniswa nezinhlobo ezimbili ze-cellulose, i-hydroxyyethyl celtulose inokugcinwa kwamanzi okungcono, ngeke ilahlekelwe ukugcinwa kwamanzi ngenxa ye-gelatin ekushiseni okuphezulu, futhi inokuphikiswa okukodwa. Ngokucatshangelwa kokusebenza, kunconywa ukusebenzisa i-hydroxyethyl celtulose nge-viscosic ka-100,000 njengomuntu omkhulu wokupenda ngamatshe wangempela.
