Thuthukisa ukusebenza kwezinto zokwakha - i-hydroxypropyl methylcellulose

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 ku-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 esekwe nge-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 (dispersion degree 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 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.
