Ibanga lansuku zonke lamakhemikhali i-hydroxypropyl methylcellulose iyi-polymer yokwenziwa eyenziwe ngamalitha kakotini we-cellulose wemvelo ngokuguqulwa kwe-etherification.I-Cellulose ether iphuma ku-cellulose yemvelo.Ukukhiqizwa kwe-cellulose ether kuhlukile kuma-polymers okwenziwa.Impahla yayo eyisisekelo kakhulu i-cellulose, isakhi se-polymer yemvelo.Ngenxa yemininingwane yesakhiwo se-cellulose yemvelo, i-cellulose ngokwayo ayinalo ikhono lokusabela nge-etherification agents.Kodwa-ke, ngemva kokwelashwa kwe-ejenti yokuvuvukala, izibopho eziqinile ze-hydrogen phakathi kwamaketanga amangqamuzana namaketanga ziyabhujiswa, futhi ukukhululwa okusebenzayo kweqembu le-hydroxyl kuba i-alkali cellulose esebenzayo.Thola i-cellulose ether.
Ibanga lansuku zonke lamakhemikhali i-hydroxypropyl methylcellulose iyimpushana emhlophe noma ephuzi kancane, futhi ayinaphunga, ayinambitheki futhi ayinabuthi.I-solvent engasakazwa ngokushesha emanzini abandayo futhi ihlanganiswe ne-organic matter, futhi ifinyelele ukuvumelana okuphezulu ngemizuzu embalwa ukwenza isisombululo se-viscous esisobala.Uketshezi lwamanzi lunomsebenzi ongaphezulu, ukukhanya okuphezulu, ukuzinza okuqinile, futhi aluthintwa i-pH uma luncibilika emanzini.Inemiphumela yokuqina kanye ne-antifreeze kuma-shampoos namajeli okugeza, futhi inokugcina amanzi kanye nezakhiwo ezinhle zokwenza ifilimu zezinwele nesikhumba.Ngokukhuphuka okubukhali kwezinto zokusetshenziswa eziyisisekelo, i-cellulose (i-antifreeze thickener) esetshenziselwa okokuhlanza izingubo, i-shampoo, ijeli yokugeza inganciphisa kakhulu izindleko futhi ifinyelele umphumela oyifunayo.
Izici nezinzuzo zebanga lansuku zonke lamanzi abandayo we-cellulose HPMC:
1. Ukucasuka okuphansi, izinga lokushisa eliphezulu kanye nokungenabuthi;
2. Ukuzinza kwenani le-pH ebanzi, okungaqinisekisa ukuzinza kwayo ebangeni lenani le-pH 3-11;
3. Thuthukisa isimo;
4. Khulisa igwebu, uzinzise igwebu, uthuthukise ukuzwa kwesikhumba;
5. Ukuthuthukisa ngokuphumelelayo uketshezi lwesistimu.
6. Kulula ukuyisebenzisa, faka emanzini abandayo ukuze uhlakaze ngokushesha ngaphandle kokuhlanganisa
Ububanzi bokusetshenziswa kwe-HPMC yansuku zonke yamakhemikhali e-cellulose:
Isetshenziswa okokuhlanza izingubo, ishampoo, ukugeza umzimba, okokuhlanza ubuso, okokugcoba, ukhilimu, ijeli, i-toner, i-conditioner, imikhiqizo yesitayela, umuthi wokuxubha amazinyo, i-mouthwash, amanzi amabhamuza wethoyizi.
Indima ye-HPMC yansuku zonke ye-chemical grade cellulose:
Ekusetshenzisweni kwezimonyo, ikakhulukazi isetshenziselwa ukuqina, ukugwedla, i-emulsification ezinzile, ukuhlakazeka, ukunamathela, ukuthuthukiswa kwezakhiwo zefilimu kanye nokugcinwa kwamanzi kwezimonyo, imikhiqizo ye-viscosity ephezulu isetshenziselwa ukuqina, imikhiqizo e-viscosity ephansi isetshenziselwa ukumiswa. ukuhlakazeka kanye nokwenza ifilimu.
Ubuchwepheshe bansuku zonke be-cellulose yamakhemikhali e-HPMC:
I-viscosity ye-hydroxypropyl methyl fiber efanelekile embonini yamakhemikhali yansuku zonke ikakhulukazi i-100,000, 150,000, kanye ne-200,000.Ngokuvamile, i-viscosity ephezulu isetshenziswa kakhulu, futhi umphumela wokuqina ungcono kakhulu.Ngokwefomula yakho, inani lokungezwa emkhiqizweni ngokuvamile liyi-1,000.Izingxenye ezi-2 kuya kwezi-4 ngenkulungwane.
Izinyathelo zokuzivikela
I-hydroxypropyl methylcellulose yansuku zonke yamakhemikhali engafanelekile ibonisa ukungacaceli kahle, umphumela ongemuhle wokujiya, ukuncipha ngemva kokugcinwa isikhathi eside, futhi ezinye izingxenye zingase zibe nesikhunta.Ukuze ugweme imvula ye-cellulose ngesikhathi sokusetshenziswa, kufanele inyakaziswe ngaphambi kokuthi kuvele ukufana.sebenzisa.
