N'ihe eji ewu ụlọ, ọkachasị n'ihe eji arụ ụlọ dịka mkpuchi, ihe nrapado, ngwa ọkụ akọrọ, gypsum, na konkịtị, ọrụ HPMC dị ka onye na-ekesa dị oke mkpa. A na-egosipụta isi ọrụ ya n'akụkụ ndị a:

Ịkwalite mgbasa

N'ime ụfọdụ ngwa na ụlọ ọrụ ihe owuwu, dispersibility nke akụrụngwa akụrụngwa na-emetụtakarị arụmọrụ ihe owuwu na mmetụta nke ngwaahịa ahụ. Dị ka a dispersant, HPMC nwere ike n'ụzọ dị irè achụsasị siri ike irighiri na-egbochi ha aggregating ma ọ bụ precipitating na aqueous ngwọta. Site n'ịba ụba mmiri nke mmiri, HPMC nwere ike ịkwalite nkesa otu nke ihe dị na mmiri na-adabere na mmiri, na-eme ka ọ dị nro na nkwụsị nke ihe ndị a gwakọtara.

Meziwanye rheology na ịrụ ọrụ ihe owuwu

Na ngwaahịa ihe owuwu dị ka ihe nkwụnye ụlọ, mkpuchi, na ngwa ngwa akọrọ, HPMC nwere ike ịhazigharị viscosity na rheology nke ihe ndị ahụ, na-eme ka ihe ndị ahụ nwee mmetụta dị mma na ngwa ngwa n'oge usoro ihe owuwu. Nke a dị mkpa maka ịnọgide na-enwe nguzozi na ịdị mfe nke ịmepụta ngwaahịa na gburugburu ihe owuwu dị mgbagwoju anya.

Ejikwa mmiri emelitere

Na ngwa ngwa akọrọ, gypsum na ihe ndị ọzọ yiri ya, mgbakwunye nke HPMC nwere ike imezi njigide mmiri nke ihe ndị ahụ, belata ikuku mmiri na-ekpo ọkụ, na ịgbatị oge ihe owuwu. Nke a na-enye aka nke ukwuu maka eserese na ime ihe na-arụ ọrụ nke ukwuu, karịsịa na okpomọkụ dị elu na ebe akọrọ, ma nwee ike igbochi mgbawa na nkwụsịtụ n'oge a na-ewu ụlọ.

Melite adhesion na mgbochi ịwụfu Njirimara

Dị ka onye na-ekesa na nrapado ihe owuwu, HPMC nwere ike ịkwalite nrapado na mkpụrụ, meziwanye nkwụsi ike na nkwụsi ike nke ngwaahịa ikpeazụ, ma gbochie ịwụfu nke ndị agha mpụga ma ọ bụ ihe gburugburu ebe obibi kpatara.

3. Ngwa ngwa ngwa HPMC dị iche iche dị iche iche

Ngwa ngwa agwakọta akpọnwụ

Akọrọ-agwakọta ngwa agha bụ a premixed ngwa agha ihe, tumadi esịnede simenti, ájá, modifiers, wdg Dị ka a dispersant, ọrụ nke HPMC na akọrọ-mixed ngwa agha na-tumadi egosipụta n'ịkwalite ya fluidity na dispersibility na igbochi agglomeration n'etiti dị iche iche components. Site n'iji HPMC eme ihe n'ụzọ ezi uche dị na ya, ngwa agha ahụ nwere ike inwe njide mmiri ka mma ma zere mgbawa n'oge nke ikuku mmiri na-ebu ngwa ngwa kpatara.

Ihe mkpuchi ihe owuwu

Na mkpuchi mmiri, HPMC dị ka onye na-ekesa nwere ike imeziwanye mgbasa nke pigmenti, zere mmiri ozuzo pigmenti, ma hụ na nkwụsi ike nke mkpuchi. N'otu oge ahụ, HPMC nwekwara ike ịhazigharị viscosity nke mkpuchi iji mee ka ọ dịkwuo ọkwa na ịrụ ọrụ n'oge usoro eserese.

Tile adhesives na ihe nkedo

Na tile adhesives na ndị ọzọ ụlọ adhesives, dispersibility nke HPMC dịkwa ezigbo mkpa. Ọ nwere ike gbasasịa ihe njikọ ahụ nke ọma, melite arụmọrụ nke nrapado ahụ n'ozuzu ya, kwalite arụmọrụ ya na arụ ọrụ mgbochi mkpofu, yana hụ na njikọta nke ihe dị ka taịlị.

Gypsum na ciment

Gypsum na ciment bụ ihe ndị a na-ewu ewu na ụlọ ọrụ mmepụta ihe, na njikwa ha na ịdị mma na-emetụta mmetụta ụlọ. HPMC dị ka a dispersant nwere ike n'ụzọ dị irè melite fluidity na operability nke ihe ndị a, belata nguzobe nke ikuku egosipụta, na melite ike na anwụ ngwa ngwa nke ikpeazụ ngwaahịa.

4. Uru nke HPMC dị ka a dispersant

Ịrụ ọrụ dị elu

HPMC dị ka onye na-ekesa nwere ike ịrụ ọrụ dị ịrịba ama na ọnụ ọgụgụ dị ala, na ike ịgbasa ya dị ike, nke kwesịrị ekwesị maka nhazi na ntinye nke ihe ụlọ dị iche iche.

HPMC nwere ezigbo ndakọrịta na ọtụtụ ihe eji ewu ụlọ, gụnyere ciment, gypsum, ngwa agha, adhesives, wdg.

Nchekwa gburugburu ebe obibi na nchekwa

Dị ka a eke osisi cellulose ewepụtara, HPMC bụ na-adịghị egbu egbu na adịghị emerụ, na izute ụkpụrụ nke green gburugburu ebe obibi nchebe. Iji HPMC dị ka onye na-ekesa nwere ike ọ bụghị naanị ịkwalite arụmọrụ nke ngwaahịa ụlọ, kamakwa ibelata mmetụta nwere ike na gburugburu ebe obibi na ahụike ndị ọrụ.

Na-emeziwanye arụmọrụ ihe

Na mgbakwunye na ịgbasa,HPMCnwekwara ọrụ ndị ọzọ dị ka ịgbatị, njide mmiri, na mgbape mgbape, nke nwere ike imeziwanye arụmọrụ nke ihe ụlọ n'ọtụtụ akụkụ.

Dị ka ihe dị mkpa dispersant na-ewu ụlọ ọrụ, HPMC ekere òkè dị mkpa na mmepụta na-ewu dị iche iche ụlọ ihe na ya magburu onwe dispersing arụmọrụ, rheological ukpụhọde ikike na gburugburu ebe obibi nchebe àgwà. Site na mmụba na-achọwanye maka ngwaahịa dị elu yana ngwaahịa enyi na gburugburu ebe obibi na ụlọ ọrụ ihe owuwu, atụmanya ngwa nke HPMC ga-aba ụba karịa. Site n'iji ezi uche eme ihe nke HPMC, arụ ọrụ ụlọ, nkwụsi ike na ịdịte aka nke ihe ụlọ nwere ike ime ka ọ dịkwuo mma, na-enye nkwado siri ike maka mmepe mmepe nke ụlọ ọrụ mmepụta ihe.
