Sublimedgradehydroxypropyl methyl cellulose waa polymer synthetic ah oo ay diyaarisay wax ka beddel kiimikaad ee cellulose dabiiciga ah. Eter cellulose waa nooc ka mid ah cellulose dabiiciga ah, wax soo saarka ether cellulose iyo polymer synthetic waa ka duwan yahay, qalabkeeda ugu aasaasiga ah waa cellulose, xeryahooda polymer dabiiciga ah. Sababtoo ah gaar ahaan qaab dhismeedka cellulose dabiiciga ah, cellulose lafteedu ma laha awood ay ku falceliyaan wakiilka etherifying, laakiin ka dib markii wakiil barar ka baaraandegidda, iyo silsilad ku dhex jira bonds adag hydrogen u dhexeeya silsilad molecular waa la burburiyaa, dhaqdhaqaaqa kooxaha hydroxyl. lagu sii daayo fiilada fiber-ka ayaa awood u leh in ay ka jawaabto alkali, falcelinta ka dib wakiilka etherification saldhigga OH galay ether cellulose AMA saldhig.
Sublimedgrade gaar ah 200 kun viscosity
hydroxypropyl methyl cellulose waa caddaan ama wax yar oo leh budo yar oo huruud ah, iyo ur aan lahayn, dhadhamin, aan sun ahayn. Waxay ku milmi kartaa biyo qabow iyo isku dhafka organic ee dareerayaasha, samaynta xal hufan oo hufan. dareeraha biyaha ayaa leh hawlo dusha sare ah, daah-furnaan sare, xasillooni xoog leh, milanka biyaha ma saameynayso PH. Waxay leedahay saameyn adag oo barafaysan shaambo iyo jel-ka qubeyska, waxayna leedahay haynta biyaha iyo samaynta filim wanaagsan oo timaha iyo maqaarka u leh. Iyada oo kor u kaca alaabta ceeriin ee aasaasiga ah, cellulose (qashin-qashin-qaboojiye) ayaa loo isticmaali karaa shaambo iyo jelka qubeyska qiimo jaban oo weli lagu gaaro natiijooyin la jecel yahay.
Astaamaha iyo faa'iidooyinka HPMC cellulose-ka-buuxinta:
1. Xanaaqa hoose, heerkulka sare iyo galmada;
2 xasilloonida pH ballaaran, oo lagu dammaanad qaaday pH ee 3-11;
3. Xooga saar caqli-galnimada;
4 kordhi oo deji goobooyin oo hagaaji maqaarka
dareen:
5. Si wax ku ool ah u wanaaji qulqulka nidaamka.
Hooska codsiga HPMC fiber-ka sare:
Waxaa loo isticmaalaa shaambada, dhaqidda jirka, nadiifiyaha wejiga, labeen, kareem, jel, toner, timo qaboojiyaha, alaabada qaabeynta, daawada cadayga, dhaqidda afka, biyaha xumbo.
Sublimedgrade cellulose HPMC doorka.
Codsiga incosmetic, inta badan loo isticmaalo dhumucyada la isku qurxiyo, xumbo, xasilloon
emulsification, kala firdhinta, xabagta, filimada iyo haynta biyaha hagaajinta, wax soo saarka viscosity sare loo isticmaalo dhumucdiisuna, wax soo saarka viscosity hoose inta badan loo isticmaalo kala firdhiso ganaax iyo filimada.
Tignoolajiyada HPMC ee cellulose-ga sare leh:
Hydroxypropyl methyl fiber viscosity warshadaha kiimikada maalinlaha ah inta badan waa 100,000, 150,000, 200,000 iyo wixii la mid ah.
