ʻO nā huahana Hydroxypropyl Methyl Cellulose ka nui o ka hoʻohana ʻana ma ka wahi o ka polymerization hoʻokuʻu o vinyl chloride ma Kina. I ka polymerization hoʻokuʻu o vinyl chloride, ʻo ka dispersed system ka hopena pololei i ka huahana, PVC resin, a me ka maikaʻi o kāna hana a me nā huahana. Kōkua ʻo HydroxypropylMethylCellulose i ka hoʻomaikaʻi ʻana i ke kūpaʻa wela o ka resin a me ka mālama ʻana i ka hāʻawi ʻana i ka nui.ʻO ka resin PVC i hana ʻia mai ka HydroxypropylMethylCellulose kiʻekiʻe ʻaʻole hiki ke hōʻoia i ka laina hana me nā kūlana honua, akā hiki ke loaʻa i nā waiwai kino maikaʻi, nā waiwai ʻāpana maikaʻi a me nā ʻano hoʻoheheʻe rheological maikaʻi loa.
I ka hana ʻana i nā resins synthetic, e like me ka polyvinyl chloride, polyvinylidene chloride, a me nā copolymers ʻē aʻe, ʻo ka polymerization suspension ka mea maʻamau i hoʻohana ʻia a pono nā monomers hydrophobic invariant i hoʻokuʻu ʻia i ka wai. Ma ke ʻano he polymers hiki ke hoʻoheheʻe ʻia i ka wai, HydroxypropylMethylCellulose huahana he hana maikaʻi o ka ʻili a me ka hana ma ke ʻano he mea pale colloidal. Hiki i ka HydroxypropylMethylCellulose ke pale pono i nā ʻāpana polymeric mai ka hana ʻana a me ka agglomeration. Eia kekahi, ʻoiai ʻo HydroxypropylMethylCellulose he polymer hiki ke hoʻoheheʻe ʻia i ka wai, hiki ke hoʻoheheʻe iki ʻia i nā monomers hydrophobic a hiki ke hoʻonui i ka porosity monomer no ka hana ʻana i nā ʻāpana polymeric.
Eia kekahi, ua hōʻike nā haʻawina i ke kaʻina hana o PVC, hoʻohana nā ʻoihana ʻē aʻe i nā ʻōnaehana hoʻopuehu ʻē aʻe, no laila ʻokoʻa nā waiwai o waho o ka PVC i hana ʻia, a no laila hiki i ka HydroxypropylMethylCellulose ke hoʻopili i ka hana hana o nā resins PVC. I loko o ka ʻōnaehana dispersing agent composite, hiki ke loaʻa nā hopena like ʻole o ka polyvinyl alcohol (PVA) o ka resin dispersing polyvinyl (PVA) me nā degere polymerization a me ka hydroxypropyl methyl cellulose (HPMC) i nā hopena like ʻole i ka hana hana. Ua hōʻike ʻia nā hoʻāʻo e ʻoi aku ka maikaʻi o ka hui o HydroxypropylMethylCellulose a me KP-08/KZ-04 me ka pae alcoholysis o 68% -75% a maikaʻi hoʻi no ka porosity o ka resin a me ka absorption o nā plasticizers.
