Ngwa nke hydroxypropyl methylcellulose na ngwa agha

1. Njide mmiri

Hydroxypropyl methylcellulose maka owuwu na-egbochi mmiri ịbanye n'ime mgbidi. Ọnụ mmiri kwesịrị ekwesị na-anọ na ngwa ngwa, nke mere na ciment nwere ogologo oge iji mee ka mmiri na-ekpo ọkụ. Njide mmiri na-adaba na viscosity nke cellulose ether ngwọta na ngwa agha. Nke dị elu nke viscosity, ka mma na-ejigide mmiri. Ozugbo ụmụ irighiri mmiri na-abawanye, njide mmiri na-ebelata. N'ihi na maka otu ego nke ihe owuwu-kpọmkwem hydroxypropyl methylcellulose ngwọta, mmụba nke ọnụ ọgụgụ mmiri pụtara mbelata na viscosity. Ọganihu nke njide mmiri ga-eduga n'ịgbatị oge ọgwụgwọ nke ngwa agha a na-arụ.

2. Melite constructability

Ngwa nke hydroxypropyl methylcellulose HPMC nwere ike melite owuwu nke ngwa agha, mee ka ngwa ngwa na-arụ ọrụ na-agbasa nke ọma, belata nrapado na ngwá ọrụ, mee ka ihe owuwu ahụ dịkwuo mfe, ma belata ike anụ ahụ nke ndị ọrụ.

3. Afụ ọdịnaya

Ọdịnaya afụ ikuku dị elu na-ebute mpụta ngwa agha ka mma yana ịrụ ọrụ nke ọma, na-ebelata nhazi mgbape. Ọ na-ebelata uru nke ike, na-ebute ihe ngosi "mmiri mmiri". Ọdịnaya afụ ikuku na-adaberekarị na oge mkpali. A na-eji ngwaahịa eme ihe n'ọtụtụ ebe iji melite arụmọrụ nke ihe ụlọ hydraulic, dị ka ciment na gypsum. N'ime ụrọ ndị dabeere na ciment, ọ na-eme ka njide mmiri dịkwuo mma, na-abawanye mmezi na oge na-emeghe, ma na-ebelata nkwụsị.

4. Anti-sagging

Ngwa agha dị mma na-eguzogide sag pụtara na mgbe etinyere ya na akwa akwa ọ nweghị ihe egwu nke sag ma ọ bụ mgbada ala. Enwere ike imezi nkwụsi ike nke sag site na hydroxypropyl methylcellulose akọwapụtara nke ọma. Karịsịa hydroxypropyl methylcellulose emepụtara ọhụrụ maka ihe owuwu nwere ike inye mma mgbochi mgbochi nke ngwa agha.

5. Wetting ike

Kwesịrị ekwesị cellulose ether ngwaahịa nwere ike melite viscosity nke ngwa agha mgbe huu n'elu ọrụ na mmiri adhesion nke ngwa agha, nke na-eme ka ngwa agha nwere mma arụmọrụ na wetting na mkpụrụ, ọbụna ma ọ bụrụ na ọ na-etinyere EPS ma ọ bụ XPS, wdg A ga-enwe. ọ dịghị curling na-abụghị wetting onu na pụrụ iche isi elu.
