I-Hydroxypropyl methylcellulose (i-HPMC ngamafuphi) i-ether ebalulekile exubene, okuyi-polymer engeyona i-ionic emanzini, futhi isetshenziswa kabanzi ekudleni, emithini, embonini yamakhemikhali yansuku zonke, ukumboza, ukusabela kwe-polymerization kanye nokwakhiwa njengendlela yokumiswa kokuhlakazeka, ukuqina, emulsifying, stabilizing and adhesives, njll, futhi kukhona igebe elikhulu emakethe yasekhaya.
I-Hydroxypropyl methylcellulose isetshenziswa kabanzi embonini yezokwakha njenge-ejenti eyenza ifilimu, i-binder, i-dispersant, i-stabilizer, i-thickener, umgqugquzeli wamanzi, njll., futhi isibe umkhiqizo wenkanyezi oye waheha ukunaka kusukela yethulwa kulayini.
I-Hydroxypropylmethylcellulose
Igama eligcwele lesiNgisi: Hydroxypropyl Methyl Cellulose Isifinyezo sesiNgisi: HPMC
Ngenxa yokuthi i-HPMC inezakhiwo ezinhle kakhulu ezifana nokuqina, i-emulsification, ukwakheka kwefilimu, i-colloid evikelayo, ukugcinwa komswakama, ukunamathela, ukumelana ne-enzyme kanye nokungabi namandla kwe-metabolic, isetshenziswa kabanzi kuma-coatings, ukusabela kwe-polymerization, izinto zokwakha, ukukhiqizwa kukawoyela, izindwangu, ukudla, imithi, Izinto zobumba ezisetshenziswa nsuku zonke, izinto zikagesi kanye nembewu yezolimo neminye iminyango.
izinto zokwakha
Ezimpahleni zokwakha, i-HPMC noma i-MC ivamise ukungezwa kusimende, udaka, nodaka ukuze kuthuthukiswe izakhiwo zokwakha kanye nokugcinwa kwamanzi.
Ingasetshenziswa njenge:
1). I-adhesive ne-caulking agent ye-gypsum-based adhesive tape;
2). Ukuhlanganiswa kwezitini ezisekelwe kusimende, amathayili nezisekelo;
3). I-stucco esekelwe ku-plasterboard;
4). I-plaster yesakhiwo esekwe kusimende;
5). Kufomula yopende kanye nesikhiphi sepende.
I-Adhesive yamathayili e-ceramic
HPMC 15.3 izingxenye
Perlite 19.1 izingxenye
Ama-amide anamafutha kanye ne-cyclic thio compounds 2.0 izingxenye
Ubumba 95.4 izingxenye
I-silica seasoning (22μ) izingxenye ezingu-420
450.4 izingxenye zamanzi
Isetshenziswa kusimende eboshwe ngezitini ezingaphili, amathayela, amatshe noma usimende:
HPMC (dispersion degree 1.3) 0.3 izingxenye
Catelan usimende izingxenye 100
Isihlabathi se-silika 50 izingxenye
50 izingxenye zamanzi
Isetshenziswa njengesengezo sezinto zokwakha zikasimende ezinamandla aphezulu:
Catelan usimende izingxenye 100
Asbestos 5 izingxenye
Ukulungisa utshwala be-Polyvinyl 1 ingxenye
I-calcium silicate izingxenye ezingu-15
Ubumba 0.5 izingxenye
32 izingxenye zamanzi
HPMC 0.8 izingxenye
Imboni kapende
Embonini kapende, i-HPMC isetshenziswa kakhulu kupende we-latex nasezintweni zikapende ezincibilika emanzini njenge-ejenti yokwakha ifilimu, i-thickener, emulsifier ne-stabilizer.
Ukumiswa kwePolymerization ye-PVC
Inkambu esetshenziswa kakhulu imikhiqizo ye-HPMC ezweni lami i-polymerization yokumiswa kwe-vinyl chloride. Ekumisweni kwe-polymerization ye-vinyl chloride, uhlelo lokusabalalisa luthinta ngokuqondile ikhwalithi yomkhiqizo we-PVC resin kanye nokucubungula kwayo nemikhiqizo; ingathuthukisa ukuzinza okushisayo kwe-resin futhi ilawule ukusabalalisa usayizi wezinhlayiyana (okungukuthi, ukulungisa ukuminyana kwe-PVC). Inani le-HPMC libalelwa ku-0.025%~0.03 wokuphuma kwe-PVC %.
I-resin ye-PVC elungiselelwe i-HPMC yekhwalithi ephezulu, ngaphezu kokuqinisekisa ukuthi ukusebenza kuhlangabezana nezinga likazwelonke, futhi inezakhiwo ezinhle zomzimba, izici ezinhle kakhulu zezinhlayiya kanye nokuziphatha okuhle kakhulu kwe-rheological yokuncibilika.
enye imboni
Ezinye izimboni ikakhulukazi zihlanganisa izimonyo, ukukhiqiza uwoyela, okokuhlanza, izitsha zobumba zasendlini nezinye izimboni.
amanzi ancibilikayo
I-HPMC ingenye yama-polymers ancibilikayo emanzini, futhi ukuncibilika kwayo emanzini kuhlobene nokuqukethwe kweqembu le-methoxyl. Uma okuqukethwe kweqembu le-methoxyl kuphansi, kungancibilika ku-alkali eqinile futhi ayinalo iphuzu le-thermodynamic gelation. Ngokukhula kokuqukethwe kwe-methoxyl, izwela kakhulu ekuvuvukeni kwamanzi futhi inyibilika ekuxubeni i-alkali ne-alkali ebuthakathaka. Uma okuqukethwe kwe-methoxyl kungu>38C, ingancibilika emanzini, futhi ingancibilika kuma-halogenated hydrocarbon. Uma i-acidic periodic acid yengezwa ku-HPMC, i-HPMC izohlakaza ngokushesha emanzini ngaphandle kokukhiqiza izinto zekhekhe ezingancibiliki. Lokhu kubangelwa ikakhulukazi ukuthi i-periodic acid inamaqembu e-dihydroxyl endaweni ye-ortho ku-glycogen ehlakazekile.
