Otu esi ahọrọ hydroxypropyl methylcellulose kwesịrị ekwesị maka mgbidi ime na mputa

Otu esi ahọrọ HPMC ziri ezi

1. Dị ka ihe nlereanya: Dị ka usoro dị iche iche nke putties dị iche iche si dị, ụdị viscosity nke hydroxypropyl methylcellulose na methylcellulose dịkwa iche. A na-eji ha eme ihe site na 40,000 ruo 100,000. N'otu oge ahụ, eriri onye anaghị eri anụ ether enweghị ike dochie ọrụ nke ndị ọzọ na-ekekọta, na-agbakwụnye cellulose ether apụtaghị na ihe ndị ọzọ na-ekekọta nwere ike ibelata.

2. Ị chọrọ mmiri oyi dispersible cellulose ether: Cellulose ether (gụnyere hydroxypropyl methylcellulose na methylcellulose) bụ surfactant na elu viscosity mgbe mgbasa. Ọ bụ ihe kpatara ọdịdị a na ọ bụrụ na a na-agbakwunye cellulose ether nkịtị na mmiri, ọ dị mfe ịmepụta bọl, na n'èzí nke bọl ahụ agbazewo n'ime ngwọta dị oke mkpa, na ime ya na-ekpuchi ya, ọ na-esikwa ike. maka mmiri ịbanye n'ime ya, na-ebute mgbasa na-adịghị mma. . Ether cellulose a na-emeso elu (nke nwere ike igbu oge mgbasa) agaghị adị ka nke a, a pụkwara ịgbasa ya nke ọma na mmiri oyi (nkwụsị igbu oge, ma jiri nwayọọ nwayọọ gbazee mgbe mgbasa). Ọ bụ ezigbo nhọrọ ịghọta ọdịiche dị n'elu.

1. N'ihi na akọrọ-agwakọta n'ime ime na n'èzí mgbidi putty, n'ihi na ether cellulose e agbasawo nke ọma na ihe n'oge akọrọ-agwakọta usoro, a ga-enweghị agglomeration. Ya mere, a na-atụ aro ka iji ụdị nkịtị (ụdị mgbasa mmiri na-abụghị oyi), n'ihi na ọnụego mgbasa nke ụdị nkịtị dị ngwa ngwa karịa nke ụdị mgbasa ozi mmiri oyi, nke na-ebelata oge nchere site na ịgwakọta slurry na-ewu.

2. Maka nkwadebe nke putty nke na-agbaze ozugbo cellulose ether (gụnyere hydroxypropyl methylcellulose na methylcellulose) na mmiri ma gwakọta ya na ihe ndị ọzọ, a na-atụ aro iji mmiri oyi na-agbasa ụdị cellulose ether. Enwere ike ịgbasa ether cellulose a na-agwọ nke ọma na mmiri oyi wee gbazee (nwere ike igbu oge mgbasa)
