China Zhongtai PVC resin mea hoʻolako
Kina Zhongtai PVC resin mea hoʻolako,
pvc resin no ka paipu, ʻO ka resin PVC no ka ʻike,
ʻO ka Polyvinyl chloride (PVC) ka mea hoʻomaka o nā peroxides a me nā pūhui azo i loko o ka vinyl chloride monomer (VCM).A i ʻole ma lalo o ka hana o ka māmā a me ka wela e like me ke ʻano o ka free radical polymerization polymerization polymer.Ua kapa ʻia ʻo vinyl chloride homopolymer a me vinyl chloride copolymer.
ʻO PVC ka mea i hoʻohana nui ʻia ma ka honua a ua 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 papahele papahele, ka ʻili artificial, ka paipu, ka uea a me ke kaula, ke kiʻi ʻoniʻoni, ka ʻōmole, ka mea huʻa, ka mea hoʻopaʻa, ka fiber a pēlā aku.ʻO kāna mau hoʻohana nui he PVC profile, PVC paipu, PVC kiʻiʻoniʻoni, PVCPVC mea paʻakikī a me ka pā, nā huahana palupalu PVC maʻamau, nā mea hoʻopihapiha PVC, ka pā PVC a me ka papahele, nā mea kūʻai aku PVC, nā huahana uhi PVC, nā huahana PVC foam, PVC transparent sheet, etc. .
ʻO PVC me nā waiwai mechanical maikaʻi loa, nā waiwai kemika e like me ke kū'ēʻana i ka waikawa a me ka alkali corrosion, kūlohelohe mai ka hoʻopau ponoʻana i ke ahi, ka hoʻololi wela haʻahaʻa, ka hoʻohaʻahaʻaʻana i ka leo hoʻohaʻahaʻa leo, nā huahana o ka palekana o ka nohona, hiki ke lilo i mau hiʻohiʻona maikaʻi, e like me Ua lilo ka hoʻololi kino a me ke kemika i mea koʻikoʻi o ka hale ʻōmaʻomaʻo, ka mākeke kūkulu ʻenekinia, i loko o nā tausani, ʻoiai ʻoi aku ka nui o ka poʻe i ʻike a ʻike.I kēia manawa, ʻo zhongtai pūʻulu ʻo ia ka mea mua, ʻekolu o ka honua i nā mea hoʻolako PVC home, ua hoʻokumu i ka pālākiō o ka puka makahiki o 2.3 miliona tons o ka polyvinyl chloride (PVC) resin, hoʻoikaika ikaika i ka noi ʻana o nā huahana PVC kiʻekiʻe i nā mea āpau. hele o ke ola, 'o ia ka 'āina o ka 'ōmaʻomaʻo ulu a me ka lako aoao e hoʻokō a hoʻokō i ka hoʻoponopono, 'o ia hoʻi ka lōʻihi-manawa olakino ulu o ka 'oihana kuleana a me ka bea.Hoʻopuka nui kēia pepa i ka PVC mai nā ʻano ʻelima, e like me ka hoʻolauna, ka hoʻokaʻawale ʻana, ka hana synthesis, hoʻololi a me ka noi.
