Heerka Dhismaha HPMC

Heerka DhismahaHPMC

Heerka Dhismaha HPMC HydroxypropylMethylcellulose waa amethylcelluloseetherasal ahaankaaswaa polymer-ka molecular sare ee synthetic oo ay diyaarisay wax ka beddel kiimikaad oo dabiici ahsuuf la safeeyey ama saxarka alwaaxsida alaabta ceeriin. Soo saarista hydroxypropyl methyl cellulose (HPMC) way ka duwan tahay polymers-ka synthetic. Maadkeeda aasaasiga ah waa cellulose, oo ah ka samaysan polymer dabiici ah. Sababtoo ah qaab dhismeedka gaarka ah ee cellulose dabiiciga ah, cellulose lafteedu awood uma laha inay ka falceliyaan wakiilada etherifying. Laakiin ka dib markii wakiilka bararka la daweeyo, bonds hydrogen xoog badan oo u dhexeeya silsiladaha molecular iyo gudaha silsiladda waa la burburiyaa, iyo sii daayo firfircoon ee kooxda hydroxyl isu beddelo alkali cellulose fal-celin. Ka dib marka wakiilka etherification uu falceliyo, kooxda -OH waxaa loo beddelaa kooxda -OR.Fsi dhab ah u hel HPMC.

Heerka Dhismaha HPMCwaa budo cad oo barara xal kolloidal ah oo cad ama waxoogaa turbid ah oo biyo qabow ah. Waxay leedahay sifooyinka dhumuc, isku-xidhka, kala firdhinta, emulsification, samaynta filimka, joojinta, adsorption, gelation, dhaqdhaqaaqa dusha sare, xajinta qoyaanka iyo kolloid ilaalinta.

Xabagta Dusha

Haysashada biyaha: Hydroxypropyl methylcellulose HPMC waxay hoos u dhigi kartaa qoyaanka ay nuugaan substrate-ka iyo foornada ku jira hoobiye, oo ay ku hayaan qoyaanka ku jira binderka inta ugu badan ee suurtogalka ah, si uu hoobiyeku u ahaado mid xiran muddo dheer ka dib. . Kordhi wakhtiga furitaanka, si ay shaqaaluhu u huwadaan meel weyn mar kasta, oo ay hagaajiyaan hufnaanta dhismaha.

Hagaajinta xoogga isku xidhka oo wanaaji waxqabadka ka-hortagga simbiriirrada: hydroxypropyl methylcellulose HPMC waxay hubin kartaa in tiirarka aysan simbiriirixan doonin inta lagu jiro dhismaha, gaar ahaan kuwa culculus, marmarka iyo dhagxaanta kale.

Waxqabadka shaqada oo la hagaajiyay: Waxqabadka saliidda ee hydroxypropyl methylcellulose HPMC waxay si weyn u wanaajisaa shaqada hoobiyeyaasha, taasoo ka dhigaysa hoobiye fudud in la feedho oo la faafiyo, waxayna hagaajinaysaa hufnaanta shaqada.

Hagaajinta qoyaanka hoobiye: Hydroxypropyl methylcellulose HPMC wuxuu siinayaa joogteynta hoobiyeyaasha, waxay wanaajisaa awoodda qoynta ee hoobiye leh tiles iyo substrates, waxayna wanaajisaa xoogga isku xidhka ee hoobiye qoyan, gaar ahaan qaababka leh saamiga biyaha-cement sare.

 

Habka dahaarka derbiga dibadda (EIFS)

Awood xidhidh: Ku darida qadar ku haboonHPMChydroxypropyl methylcellulose waxay wanaajin kartaa xoogga isku xidhka ee hoobiye isku-xidhka.

Waxqabadka shaqada: Hoobiyaha ayaa lagu darayHPMChydroxypropyl methylcellulose waxay leedahay joogtayn sax ah mana sagto. Marka la isticmaalo, waxay ka dhigaysa hoobiye si fudud in la shanlo waana mid joogto ah oo aan kala go' lahayn.

Haysashada biyaha: Ku darida HPMC hydroxypropyl methyl cellulose waxay si fudud u qoysin kartaa walxaha gidaarka, fududeynaya dhejinta, oo ka dhigi kara waxyaabo kale oo dheeraad ah oo ku guuleysta saameyntooda.

Nuugista biyaha: Ku darida qaddar ku habboonHPMChydroxypropyl methylcellulose waxay yarayn kartaa hawo-mareenka waxayna yareyn kartaa nuugista biyaha ee hoobiye.
