Hydroxypropyl Methyl Cellulose HPMC ee Qalabka Dhismaha

Hydroxypropyl methylcellulose (HPMC) waa ether nonionic cellulose eter ah oo ay diyaarisay taxane farsamayn kiimiko ah oo la isticmaalayo cellulose maadada polymer dabiiciga ah sida walxo ceeriin ah. Waa budo cad oo aan ur lahayn, ur lahayn, oo aan sun ahayn oo ku barara biyo qabow oo noqda xal kolloidal cad ama wax yar oo turbid ah. Waxay leedahay sifooyinka dhumucdi, isku-xidhka, kala firdhinta, emulsifying, samaynta filim samaynta, joojinta, adsorption, gelation, dhaqdhaqaaqa dusha sare, haynta qoyaanka iyo kolloid ilaalinta. Hydroxypropyl methylcellulose, methyl cellulose waxaa loo isticmaali karaa qalabka dhismaha, warshadaha daahan, xabagta synthetic, warshadaha dhoobada, daawada, cuntada, dunta, beeraha, kiimikooyinka maalinlaha ah iyo warshadaha kale.
Hydroxypropyl methylcellulose (HPMC) Isla'egta kiimikaad:

(2) Hagaajinta iska caabbinta yaraanta iyo iska caabinta dillaaca oo wanaaji tayada dusha sare ee daahan. (3) Hagaajinta adhesion ee dusha isku xidhka si ay u bixiyaan si siman, texture siman.
5. Xabagta Tile
(1) Way fududahay in la qalajiyo maaddooyinka isku dhafka ah, ma jiraan wax ciriiri ah, hagaajinta xawaaraha codsiga, hagaajinta waxqabadka dhismaha, badbaadinta wakhtiga shaqada iyo dhimista kharashka shaqada.
(2) Hagaajinta waxtarka foornada adoo kordhinaya wakhtiga furitaanka oo bixi adhesion aad u fiican.
6. Qalabka sagxadda ee is-beddelka ah
(1) Wuxuu bixiyaa viscosity wuxuuna u dhaqmaa sidii gargaar dejin-diid. (2) Kobcinta bamka dareeraha iyo hagaajinta waxtarka jeexitaanka dhulka. (3) Xakamee haynta biyaha iyo yaraanshaha, yaraynta dildilaaca iyo yaraanshaha dhulka.
7. Rinjiga biyaha ku salaysan
(1) Waxay ka hortagtaa roobab adag waxayna kordhisaa muddada weelka alaabta. Nafley heersare ah oo la socon kara qaybaha kale. (2) Hagaajinta dareeraha, bixi caabbinta spatter wanaagsan, caabbinta sag iyo simi si loo hubiyo dhamaystirka dusha sare.
8. budada warqadda
(1) Si deg deg ah u milmi iyada oo aan la isku dhejin, taas oo u fiican isku dhafka. (2) Bixi xoogga curaarta sare.
9. xaashida sibidhka ee la soo saaray
(1) Waxay leedahay isku xirnaan sare iyo saliid waxayna xoojisaa habka wax soo saarka dibadda. (2) Hagaajinta xoogga cagaaran, kor u qaad saamaynta daaweynta fuuq-celinta, oo wanaaji wax-soo-saarka.
10. Hoobiye diyaarsan
Badeecadaha HPMC ee hoobiye-isku-dhafka ah ayaa ka wanaagsan alaabta caadiga ah ee ku jirta hoobiye diyaarsan, hubinta in shamiitada aan organic ahayn ay si buuxda u fuuqbaxday, si weyn uga hortagaysa xoogga curaarta inay sababto qallajin xad dhaaf ah, iyo dildilaaca ay keento qallajinta. HPMC sidoo kale waxay leedahay saamayn hawo-qaadid gaar ah. Badeecada HPMC ee hoobiye la isku daray ayaa leh xaddi habboon oo hawo-qaadis ah, isku mid ah iyo goobooyin yaryar, kuwaas oo wanaajin kara xoogga iyo xoqidda hoobiye-isku-darka ah. Badeecada HPMC ee sida gaarka ah loogu isticmaalo hoobiye-isku-dhafka ah ayaa leh saameyn dib-u-dhac gaar ah, kaas oo kordhin kara wakhtiga furitaanka hoobiye-isku-darka ah oo yareynaya dhibka dhismaha.
