Cellulose hydroxypropyl methyl ether waxaa laga sameeyay cellulose cudbi aad u saafi ah iyada oo loo marayo etherification gaar ah xaaladaha alkaline.
saamaynta:
1. Warshadaha dhismaha: Iyada oo ah wakiil biyaha celiya iyo dib-u-hagaajin ah oo ah hoobiyaha sibidhka, waxay ka dhigi kartaa hoobiyaha mid la bamgareyn karo. Malaasta, gypsum, budada putty ama agabka kale ee dhismaha sida xidhmo si loo hagaajiyo faafinta iyo kordhinta waqtiga shaqada. Waxaa loo isticmaali karaa sida taayilada koolada, marmarka, qurxinta balaastikada, xoojinta koolada, waxayna sidoo kale yareyn kartaa tirada sibidhka. Waxqabadka haynta biyaha ee HPMC wuxuu ka hortagaa in slurry-ku uu dillaaco sababtoo ah si dhakhso ah u engega ka dib marka la mariyo, wuxuuna xoojiyaa xoogga ka dib marka la adkeeyo.
2. Warshadaha wax soo saarka dhoobada: Waxaa si weyn loogu isticmaalaa sidii xidhmo marka la samaynayo alaabada dhoobada.
3. Warshadaha dahaarka: Waxaa loo isticmaalaa sidii dhumuc-dhegeeye, kala-firdhiye iyo xasiliye warshadaha dahaarka, waxayna leedahay iswaafajin wanaagsan oo ku saabsan biyaha ama dareerayaasha dabiiciga ah. Sida ka-saarista rinjiga.
4. Daabacaadda khad: Waxaa loo isticmaalaa sidii dhumuc-saare, kala-firdhiye iyo xasiliye warshadaha khad, waxayna leedahay iswaafajin wanaagsan oo ku saabsan biyaha ama dareerayaasha dabiiciga ah.
5. Balaastikada: waxaa loo isticmaalaa sidii wakiilka sii daynta, jilciyaha, saliidaynta, iwm.
6. Polyvinyl chloride: Waxaa loo isticmaalaa sidii kala firdhiye soo saarista polyvinyl chloride, waana wakiilka ugu weyn ee kaalmaynta diyaarinta PVC iyadoo la adeegsanayo polymerization-ka joojinta.
7. Warshadaha dawooyinka: agabka dahaarka; agabka filimada; agabka polymer-ka ee xakameeya heerka loogu talagalay diyaarinta sii-deynta joogtada ah; dejiyayaasha; wakiilada sudhitaanka; dhejisyada kiniiniga; wakiilada sii kordhaya viscosity
