Ibanga lansuku zonke lamakhemikhali i-hydroxypropyl methylcellulose i-polymer yokwenziwa eyenziwe nge-cellulose yemvelo ngokuguqulwa kwamakhemikhali. 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 ayinabo ubuthi. Ingancibilika emanzini abandayo kanye ne-solvent exubile ye-organic matter ukuze yakhe isixazululo 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, ukusetshenziswa kwe-cellulose (antifreeze thickener) ku-shampoo kanye nejeli yokugeza kunganciphisa kakhulu izindleko futhi kufinyelele umphumela oyifunayo.
Izici nezinzuzo zansuku zonke ze-cellulose yamakhemikhali e-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.
Ububanzi bokusetshenziswa kwe-HPMC yansuku zonke yamakhemikhali e-cellulose:
Isetshenziswa ku-shampoo, ukugeza umzimba, okokuhlanza ubuso, okokugcoba, ukhilimu, ijeli, i-toner, i-conditioner, imikhiqizo yesitayela, umuthi wokuxubha, 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 bebanga lamakhemikhali lwe-cellulose lwe-HPMC:
I-viscosity ye-hydroxypropyl methylcellulose elungele imboni yamakhemikhali yansuku zonke ikakhulukazi i-100,000, 150,000, kanye ne-200,000. Ngokusho kwefomula yakho, inani lokwengezwa emkhiqizweni ngokuvamile li-3 kuya ku-5/1000.
