Ibanga lansuku zonke lamakhemikhali i-hydroxypropyl methyl cellulose

Ibanga lansuku zonke lamakhemikhali i-hydroxypropyl methyl cellulose iyi-polymer yokwenziwa elungiswe ukuguqulwa kwamakhemikhali kwe-cellulose yemvelo njengento eluhlaza. I-Cellulose ether iphuma ku-cellulose yemvelo, ukukhiqizwa kwe-cellulose ether kanye ne-polymer yokwenziwa kwehlukile, impahla yayo eyisisekelo i-cellulose, inhlanganisela ye-polymer yemvelo. Ngenxa yokukhethekile kwesakhiwo se-cellulose yemvelo, i-cellulose ngokwayo ayinalo ikhono lokusabela nge-etherifying agents. Kodwa-ke, ngemva kokwelashwa kwe-ejenti yokuvuvukala, izibopho eziqinile ze-hydrogen phakathi nangaphakathi kwamaketanga amangqamuzana ziyabhujiswa, futhi umsebenzi weqembu le-hydroxyl ukhishwa ku-alkali cellulose enekhono lokuphendula. Ngemva kokusabela komenzeli we-etherifying, iqembu -OH liguqulelwa ku--OR iqembu ukuze kutholwe i-cellulose ether.

Ibanga lansuku zonke lamakhemikhali elikhethekile i-viscosity esheshayo engu-200 esheshayo i-hydroxypropyl methyl cellulose iyimpushana emhlophe noma ephuzi kancane, futhi ayinaphunga, ayinambitheki, ayinabuthi. Incibilika engxubeni yamanzi abandayo kanye nezincibilikisi zemvelo ukwakha isixazululo se-viscous esisobala. Isixazululo samanzi sinomsebenzi ongaphezulu, ukukhanya okuphezulu, ukuzinza okuqinile, ukuncibilika emanzini akuthintwa i-pH. Ukuqina kanye nomphumela we-antifreeze ku-shampoo nokugeza umzimba, ukugcinwa kwamanzi kanye nokwakheka okuhle kwefilimu yezinwele nesikhumba. Ngokukhula okukhulu kwezinto zokusetshenziswa eziyisisekelo, i-cellulose (i-antifreeze thickener) ingasetshenziswa ku-shampoo futhi ukugeza umzimba kunganciphisa kakhulu izindleko futhi kufinyelele imiphumela oyifunayo.

1. Izici nezinzuzo ze-HPMC yansuku zonke yamakhemikhali e-cellulose:

1, ukucasuka okuphansi, izinga lokushisa eliphezulu kanye nobulili;

2, uhla olubanzi lokuzinza kwe-pH, ngenani le-pH le-3-11 ububanzi lingaqinisekisa ukuzinza kwalo;

3. Ukwenyuka kokugcizelela ekuhlakanipheni;

4. Khulisa ibhamuza, uzinzise ibhamuza, uthuthukise umuzwa wesikhumba;

5. Ukuthuthukisa ngokuphumelelayo ukutholakala kwezimali kwesistimu.

2 nsuku zonke i-cellulose yamakhemikhali ebangeni le-HPMC isicelo sobubanzi besicelo:

Isetshenziswa ku-shampoo, ukugeza umzimba, ukuhlanza ubuso, okokugcoba, ukhilimu, ijeli, i-toner, i-conditioner, imikhiqizo yokubumba, umuthi wokuxubha, amanzi, amanzi amabhamuza wethoyizi.

3 Indima ye-HPMC yansuku zonke ye-cellulose yamakhemikhali:

Ekusetshenzisweni kwezimonyo, ikakhulukazi isetshenziselwa ukuqina, ukugwedla, i-emulsification ezinzile, ukuhlakazeka, ukunamathela, ukwakheka kwefilimu nokuthuthukiswa kokusebenza kokugcinwa kwamanzi, imikhiqizo ephezulu ye-viscosity isetshenziswa njengokuqina, imikhiqizo ephansi ye-viscosity isetshenziswa ikakhulukazi njengokuhlakazeka kokumiswa kanye nokwakhiwa kwefilimu. .

4 nsuku zonke amakhemikhali grade cellulose HPMC ubuchwepheshe:

IHydroxypropyl methyl fiber ukuze ivumelane ne-viscosity yemboni yamakhemikhali iyizinkulungwane eziyi-100, izinkulungwane eziyi-150, izinkulungwane ezingama-200, ngokusho kwefomula yabo yokukhetha inani lengezwe kumkhiqizo ngokuvamile izinkulungwane ezintathu kuya kweziyisihlanu.
