Badeecadaha Hydroxypropyl Methyl Cellulose waxay leeyihiin isticmaalka ugu badan ee aagga polymerization-ka vinyl chloride ee Shiinaha. Polymerization-ka vinyl chloride ee joojinta, nidaamka kala firdhisan wuxuu saameyn toos ah ku leeyahay badeecada, PVC resin, iyo tayada habaynteeda iyo wax soo saarkeeda. HydroxypropylMethylCellulose waxay gacan ka geysataa hagaajinta xasilloonida kulaylka ee resin iyo xakamaynta qaybinta cabbirka walxaha..Resin PVC ah oo laga sameeyay HydroxypropylMethylCellulose tayo sare leh ma aha oo kaliya inuu hubin karo heerka waxqabadka heerarka caalamiga ah, laakiin sidoo kale wuxuu yeelan karaa sifooyin jireed oo wanaagsan, sifooyin walxo oo aad u fiican iyo dhaqan rheological oo dhalaalaya oo aad u fiican.
Soo saarista resins-ka synthetic-ga ah, sida polyvinyl chloride, polyvinylidene chloride, iyo copolymers-ka kale, polymerization-ka suspension-ka ayaa ah kan ugu badan ee la isticmaalo waana inuu noqdaa monomers hydrophobic ah oo aan isbeddelin oo ku dheggan biyaha. Iyada oo ah polymers-ka biyaha ku milma, badeecada HydroxypropylMethylCellulose waxay leedahay firfircooni dusha sare oo aad u fiican waxayna u shaqeysaa sidii wakiillo ilaalin ah oo kolloidal ah. HydroxypropylMethylCellulose waxay si wax ku ool ah uga hortagi kartaa walxaha polymeric-ga inay soo saaraan oo ay isku urursadaan. Intaa waxaa dheer, inkasta oo HydroxypropylMethylCellulose ay tahay polymer-ka biyaha ku milma, waxay noqon kartaa mid si yar ugu milma monomers-ka hydrophobic-ga waxayna kordhin kartaa daloolka monomer-ka ee soo saarista walxaha polymeric-ga ah.
Intaa waxaa dheer, daraasado ayaa muujiyay in habka wax soo saarka ee PVC, shirkado kala duwan ay isticmaalaan nidaam kala duwan oo kala firdhisan, sidaa darteed sifooyinka dahaarka dibadda ee PVC-ga la soo saaray sidoo kale way kala duwan yihiin, sidaas darteed HydroxypropylMethylCellulose waxay saameyn kartaa waxqabadka habaynta ee resins-ka PVC. Nidaamka wakiilka kala firdhinta isku dhafan, resin PVC-ga la suray ee laga diyaariyey wakiilka kala firdhinta isku dhafan ee khamriga polyvinyl (PVA) oo leh darajooyin kala duwan oo aalkolo iyo polymerization ah iyo cellulose hydroxypropyl methyl (HPMC) ayaa laga yaabaa inay saameyn kala duwan ku yeeshaan waxqabadka habaynta. Tijaabooyinku waxay muujiyeen in isku-dhafka HydroxypropylMethylCellulose iyo KP-08/KZ-04 oo leh heerka alkololysis ee 68% -75% uu ka fiican yahay sidoo kalena uu faa'iido u leeyahay daloolka resin iyo nuugista balaastikada.
