Ngwongwo nke HPMC eji arụ ọrụ
1. Njide mmiri
Hydroxypropyl methyl cellulose HPMC maka ihe owuwu na-egbochi oke mmịnye mmiri site na mkpụrụ, na mmiri kwesịrị idowe na plasta dị ka o kwere mee n'oge mmecha nke gypsum solidification.A maara ihe onwunwe a dị ka njide mmiri, ọ dịkwa nhata na viscosity nke ụlọ ahụ kpọmkwem hydroxypropyl methyl cellulose HPMC ngwọta na stucco, nke dị elu nke viscosity nke ngwọta, na-abawanye ikike njide mmiri.
Ozugbo ọdịnaya mmiri na-abawanye, ikike njigide mmiri na-ebelata, n'ihi na mmiri na-arịwanye elu na-eme ka mmepụta nke hydroxypropyl methyl cellulose HPMC ngwọta, na-akpata mbelata nke viscosity.
2. Sag iguzogide
Akpụkpọ anụ nke na-eguzogide ọgwụ na-asọba na ịkwagide na-enye onye na-ewu ụlọ ohere itinye mkpuchi siri ike na-enweghị ntụgharị kwụ ọtọ, nke pụtakwara na stucco n'onwe ya bụ thixotropic, ma ọ bụghị ya, ọ na-agbada ala n'oge a na-ewu ya.
3. Belata viscosity, mfe ewu
Site na-agbakwụnye a dịgasị iche iche nke ụlọ pụrụ iche hydroxypropyl methyl cellulose HPMC ngwaahịa, ala viscosity na mfe ewu nwere ike nweta si gypsum plasta, iji ala viscosity larịị ụlọ raara onwe ya nye hydroxypropyl methyl cellulose HPMC, dịtụ obere viscosity na mfe ewu, Otú ọ dị, ala viscosity ụlọ raara nye. hydroxypropyl methyl cellulose HPMC ike njide mmiri adịghị ike, ọ dị mkpa ịkwalite ego agbakwunyere.
4. Ike uto nke stucco
Maka ọnụ ọgụgụ a na-akwụ ụgwọ nke ụrọ akọrọ, ọ na-adịkwu ọnụ ahịa iji mepụta ụda mmiri mmiri dị elu, nke a ga-enweta site n'ịgbakwunye mmiri na egosipụta.Mana oke mmiri na afụ nwere ike imebi ike.

Ngwa HPMC na ihe owuwu:

9.Extrusion ịkpụzi efere ciment
(1) nwere nnukwu cohesiveness na mmanu, welie nhazi arụmọrụ nke extrusion ngwaahịa.
(2) Meziwanye ike akwụkwọ ndụ akwụkwọ ndụ, kwalite mmetụta ọgwụgwọ hydration, mụbaa mkpụrụ nke ngwaahịa emechara.

10. ngwa agha eburula ụzọ
na premixed ngwa agha mmiri njigide dị mma karịa ndị nkịtị ngwaahịa, iji hụ na zuru hydration nke inorganic cementitious ihe, budata gbochie ihicha ngwa ngwa kpatara mbelata nkekọ ike, na ihicha shrinkage mere site cracking.HPMC nwekwara ụfọdụ ikuku entraining mmetụta, premixed ngwa agha pụrụ iche HPMC ngwaahịa, ikuku entraining nri ego, edo na obere egosipụta, nwere ike melite ike na gloss nke premixed ngwa agha.Premixed ngwa agha pụrụ iche HPMC ngwaahịa nwere ụfọdụ slowing mmetụta, nwere ike ịgbatị oge oghere nke premixed ngwa agha, belata ihe isi ike nke ewu.
