Polyvinyl Chloride (PVC)

Hiki ke hoʻomaikaʻi ʻia nā huahana QualiCell Hydroxypropyl Methyl Cellulose HPMC e nā waiwai i loko o PVC:
· nā mea hoʻopanee hoʻohana maʻamau.
· Hoʻomalu i ka nui o nā ʻāpana a me kā lākou mahele
· Hoʻololi i ka porosity
· E wehewehe i ke kaumaha nui o PVC.

Cellulose etera no ka Polyvinyl Chloride (PVC)

ʻO ka Polyvinyl Chloride (PVC) kahi polymer thermoplastic waiwai a versatile i hoʻohana nui ʻia i ka hale a me ka ʻoihana hana e hana i nā kiʻi puka a me ka puka makani, nā paipu (inu a me ka wai ʻino), ka uea a me ke kelepona insulation, nā lāʻau lapaʻau, etc. ʻO ia ke kolu o ka thermoplastic nui loa o ka honua. mea ma ka leo ma hope o ka polyethylene a me ka polypropylene.

Hoʻohana nui ʻia ʻo PVC ma waena o kahi ākea o ka ʻenehana, ʻenehana a me nā noi o kēlā me kēia lā me ka hoʻohana nui ʻana i ke kūkulu hale, ka lawe ʻana, ka hoʻopili ʻana, nā uila / uila a me nā noi olakino.

Polyvinyl-Chloride-(PVC)

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 Hydroxypropyl MethylCellulose i ka hoʻomaikaʻi ʻana i ke kūpaʻa wela o ka resin a me ka hoʻopaʻa ʻana i ka hāʻawi ʻana i ka nui o nā ʻāpana (ma nā huaʻōlelo ʻē aʻe, e hoʻoponopono i ka density PVC), a ʻo kāna nui he 0.025% -0.03% o ka hana PVC.ʻO ka resin PVC i hana ʻia mai ka Hydroxypropyl MethylCellulose kiʻekiʻe ʻaʻole hiki ke hōʻoia i ka laina hana me nā kūlana honua, akā hiki nō ke loaʻa nā waiwai kino maikaʻi, nā waiwai ʻāpana maikaʻi a me nā ʻano hoʻoheheʻe rheological maikaʻi loa.

ʻO PVC kahi mea paʻa loa a lōʻihi loa e hiki ke hoʻohana ʻia i nā ʻano hana like ʻole, ʻo ka paʻakikī a i ʻole ka maʻalahi, ke keʻokeʻo a i ʻole ʻeleʻele a me ka laulā o nā kala ma waena.

I ka hana ʻana i nā resins synthetic, e like me ka polyvinyl chloride (PVC), 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, ʻo Hydroxypropyl MethylCellulose ka huahana maikaʻi loa o ka ʻili a me nā hana ma ke ʻano he mea pale colloidal.Hiki i ka Hydroxypropyl MethylCellulose ke pale pono i nā ʻāpana polymeric mai ka hana ʻana a me ka agglomeration.Eia kekahi, ʻoiai ʻo Hydroxypropyl MethylCellulose 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.
