ʻOi aku ma mua o 100 mau makahiki o ka ʻoihana plastik, akā ʻaʻole i hana ʻia ka polyethylene a hiki i ka makahiki 1930. Mai kona ʻike ʻia ʻana i ka makahiki 1933, ua ulu ʻo Polyethylene (PE) i hoʻokahi o nā mea thermoplastic i hoʻohana nui ʻia a ʻike ʻia ma ka honua. Hoʻolālā nui ʻia nā resins PE hou o kēia lā no nā noi ʻoi aku ka paʻakikī e like me ke kinoea a me ka paipu wai i hoʻopaʻa ʻia i ke kaomi, nā membrane landfill, nā pahu wahie kaʻa a me nā noi koi ʻē aʻe. ʻO nā polymers i hana wale ʻia me ke kalapona a me ka hydrogen i kapa ʻia he polyolefins. No kēia hui ʻo Polyethylene (PE). he thermoplastic semicrystaline ia. ʻO Poiyethyiene ka polymer maʻamau i ʻike nui ʻia. ʻO ke ʻano kemika: (CH2-CHz)nHe huahana hydrocarbon aloha kaiapuni ia.
CHUANGRONGhe ʻoihana hoʻohui ʻoihana a me ke kālepa, i hoʻokumu ʻia i ka makahiki 2005 e kālele ana i ka hana ʻana o nā paipu HDPE, Fittings & Valves, PPR Pipes, Fittings & Valves, PP compression fittings & Valves, a me ke kūʻai aku ʻana i nā mīkini welding paipu plastik, nā mea hana paipu, ka mea hoʻopaʻa hoʻoponopono paipu a pēlā aku.
Inā makemake ʻoe i nā kikoʻī hou aku, e ʻoluʻolu e leka uila mai iā mākou +86-28-84319855, chuangrong@cdchuangrong.com, www.cdchuangrong.com
