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.
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.
Bizinto zokwakha
Ezimpahleni zokwakha, i-HPMC noma i-MC ivamise ukungezwa kusimende, udaka, nodaka ukuze kuthuthukiswe izakhiwo zokwakha kanye nokugcinwa kwamanzi.
I-HPMC ingasetshenziswa ku:
1).I-adhesive and 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 ngosimende;
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
Clay 95.4 izingxenye
I-silica seasoning (22μ) izingxenye ezingu-420
450.4 izingxenye zamanzi
Isetshenziswa kusimende eboshwe ngezitini ezingaphili, amathayela, amatshe noma usimende:
HPMC (degree of ukuhlakazwa 1.3) 0.3 izingxenye
Catelan usimende izingxenye 100
Isihlabathi se-silica izingxenye ezingu-50
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 kanye nezingxenye zopende ze-resin ezincibilika emanzini njenge-ejenti yokwakha ifilimu, i-thickener, i-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 lokuhlakazeka luthinta ngqo 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-PVC resin 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.
Oembonini
Ezinye izimboni ikakhulukazi zihlanganisa izimonyo, ukukhiqiza uwoyela, okokuhlanza, izitsha zobumba zasendlini nezinye izimboni.
Wi-ater encibilikayo
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.
