E pili ana i kēia mea
Pono hale - Pono e hoʻohana no nā lima ma nā hana o ka home e like me ka holoi ʻana i nā kīʻaha, hoʻomaʻemaʻe, mālama i kahi ʻelemakule, hoʻonohonoho pua a me nā mea hou aku.
ʻO ka pale lima lōʻihi - ʻO nā mea PVC kiʻekiʻe a me ka wai ʻole me ke ʻano pua ma ka ʻāpana lima o kēia mau mīkina lima
ʻO Polyvinyl chloride (PVC) ka mea hoʻomaka o ka vinyl chloride monomer (VCM) i loko o ka peroxide, nā hui azo, a me nā mea ʻē aʻe ma lalo o ka hana o ka māmā a me ka wela e like me ka free radical polymerization reaction mechanism of polymer.The homopolymer of vinyl chloride and the copolymer o ka vinyl chloride ua kapaia he vinyl chloride resins.
ʻO PVC no ka hana amorphous o ka pauka keʻokeʻo, he liʻiliʻi ke degere branched, pili 1.4, ke aniani hoʻololi wela o 77 ~ 90℃, 170℃a pēlā paha i hoʻomaka ai e decompose, maikaʻi ʻole i ka wela a me ka māmā, ma mua o 100℃a i ʻole ka lā no ka manawa lōʻihi, e decompose a hoʻohua i ka hydrogen chloride, a ʻoi aku ka decomposition catalytic hou aʻe, ke kumu o ka discoloration, nā waiwai kino a me nā mechanical i hāʻule wikiwiki hoʻi, I ka hoʻomaʻamaʻa, pono e hoʻohui ʻia nā stabilizers e hoʻomaikaʻi i ka wela a me ka māmā.
ʻO ke kaumaha o ka molecular PVC i hana ʻia e ka ʻoihana ma ke ʻano he 50,000 ~ 110,000, me ka polydispersity nui, a piʻi ka paona mole me ka emi ʻana o ka mahana polymerization; ʻAʻohe wahi hoʻoheheʻe paʻa, 80 ~ 85℃e palupalu, 130℃i ke kūlana viscoelastic, 160 ~ 180℃e hoʻololi i loko o viscous kahe moku; He maikai mechanical waiwai, tensile ikaika e pili ana i 60MPa, hopena ikaika o 5 ~ 10kJ/m2; Excellent dielectric waiwai.
ʻO PVC ka mea hana nui loa o ka honua i nā plastics maʻamau, hoʻohana nui ʻia. Hoʻohana nui ʻia ia i nā mea kūkulu hale, nā huahana ʻoihana, nā mea e pono ai i kēlā me kēia lā, ka ʻili papahele, ka tile papahele, ka ʻili artificial, ka paipu, ka uwea a me ke kaula, ke kiʻi ʻoniʻoni, ka hue. , mea hu'ahu'a, mea sila, fiber a pela aku.
