Ọrụ nke hydroxypropyl methyl cellulose na ngwa agha mmiri

Ọrụ nkeHPMCn'ime ngwa agha mmiri

Ngwakọta ngwakọta mmiri: Ngwakọta ngwakọta bụ ụdị simenti, ngwakọta dị nro, ngwakọta na mmiri, dịka ihe dị iche iche si dị, n'ókè ụfọdụ, mgbe a tụchara ya n'ebe a na-agwakọta ihe, a na-agwakọta ya, ebuga ya n'ebe gwongworo ahụ ji, n'ime akpa nchekwa raara onwe ya nye, ma jiri ya mee ihe n'oge akọwapụtara ngwakọta mmiri emechara.

A na-eji Hydroxypropyl methyl cellulose eme ihe dị ka ihe na-ejide mmiri maka simenti, na-eme ka mmiri gbapụta. Na gypsum dị ka ihe na-ejikọ iji melite ojiji ma gbasaa oge ọrụ, hydroxypropyl methylcellulose HPMC na-ejide mmiri ka mmiri gbazee mgbe ọ kpọrọ nkụ ghara ịdị oke ọsọ ma gbawaa, na-eme ka ike ya sie ike. Nchekwa mmiri bụ ihe dị mkpa nke hydroxypropyl methyl cellulose HPMC, ọ bụkwa nchegbu nke ọtụtụ ndị na-emepụta moto mmiri. Ihe ndị na-emetụta mmetụta njigide mmiri nke moto mmiri gụnyere ọnụọgụ HPMC agbakwunyere, viscosity nke HPMC, ịdị mma nke ihe ndị ahụ na okpomọkụ nke gburugburu ebe obibi eji.
Hydroxypropyl methyl cellulose HPMC na moto mmiri bụ isi ọrụ n'akụkụ atọ, otu bụ ikike ijide mmiri nke ọma, nke abụọ bụ nguzozi moto mmiri na thixotropy nke mmetụta, nke atọ bụ mmekọrịta ya na simenti. Njide mmiri Cellulose ether dabere na ọnụego nnabata mmiri nke ntọala ahụ, nhazi moto mmiri, ọkpụrụkpụ oyi akwa moto, mkpa mmiri moto, na oge ntọala. Ka nghọta nke hydroxypropyl methyl cellulose dị elu, otú ahụ ka njide mmiri ka mma.
Ihe ndị na-emetụta njide mmiri nke ihe e ji amị mmiri gụnyere viscosity nke cellulose ether, mmụba nke ọnụọgụgụ, nha ihe na okpomọkụ. Ka viscosity nke cellulose ether na-amụbawanye, otú ahụ ka njide mmiri ka mma. Viscosity bụ paramita dị mkpa maka arụmọrụ HPMC. Maka otu ngwaahịa ahụ, iji ụzọ dị iche iche tụọ viscosity nke nsonaazụ ya dịgasị iche iche, ụfọdụ ọbụna site na ihe abụọ. Ya mere, a ga-eme ntụnyere viscosity ahụ n'otu usoro nnwale ahụ, gụnyere okpomọkụ, rotor, wdg.

N'ikwu ya n'ozuzu, ka viscosity dị elu, otú ahụ ka nchekwa mmiri ka mma. Agbanyeghị, ka viscosity dị elu, otú ahụ ka ibu molekul nke HPMC dị elu, na otú HPMC si agbaze nke ọma, nke nwere mmetụta ọjọọ na ike na arụmọrụ owuwu nke mortar. Ka viscosity dị elu, otú ahụ ka mmetụta thickening nke mortar si apụta ìhè, mana ọ bụghị ihe jikọrọ ya kpọmkwem. Ka viscosity dị elu, otú ahụ ka stablet mmiri si apụta, otú ahụ ka stablet mmiri si apụta, arụmọrụ owuwu dị mma, arụmọrụ scraper viscous na nrapado dị elu na substrate. Agbanyeghị, mmezi nke ike nhazi nke mortar mmiri n'onwe ya enyereghị aka. Ma owuwu ahụ, arụmọrụ ahụ abụghị arụmọrụ mgbochi-nkwụchi doro anya. N'ụzọ dị iche, ụfọdụ viscosity dị ọkara na obere mana hydroxypropyl methylcellulose agbanwere agbanwe nwere arụmọrụ dị mma n'imeziwanye ike nhazi nke mortar mmiri.
Ka a na-agbakwụnyekwu ihe e ji mee ka mmiri dị n'ime selulose ether PMC, otú ahụ ka ọ ga-esi na-ejide mmiri nke ọma, otú ahụ ka ọ ga-esi na-enwu nke ọma, otú ahụ ka ọ ga-esi na-ejide mmiri nke ọma. Ịdị mma bụkwa ihe dị mkpa maka arụmọrụ nke hydroxypropyl methyl cellulose.
Ịdị mma nke hydroxypropyl methyl cellulose nwekwara mmetụta ụfọdụ na njigide mmiri ya. N'ọnọdụ nkịtị, otu viscosity na ịdị mma dị iche iche nke hydroxypropyl methyl cellulose, n'okpuru otu ọnụọgụ mgbakwunye ahụ, obere ịdị mma nke mmetụta njigide mmiri ka mma.
N'ime ite mmiri, mgbakwunye nke cellulose etherHPMCdị obere nke ukwuu, mana ọ nwere ike ime ka arụmọrụ owuwu nke ngwa agha mmiri ka mma nke ukwuu, ọ bụ ihe mgbakwunye bụ isi nke na-emetụta arụmọrụ nke ngwa agha mmiri. Arụmọrụ nke ngwa agha mmiri na-emetụta nke ukwuu site na nhọrọ ezi uche dị na ya nke hydroxypropyl methyl cellulose.
