Na lako o na mea paani maalea
"Vinyl", "Resin", "PU resin", "PVC", "Polystone", ke manaʻoʻiʻo nei au ua lohe nā hoaaloha makemake i nā mea pāʻani i kēia mau huaʻōlelo.
He aha kēia mau mea? He ilikai lakou a pau? Ua ʻoi aku ka maikaʻi o ka resin ma mua o ka vinyl?
Pihoihoi nā mea a pau e pili ana i kēia mau pilikia o nā mea hana a me ka hana lima.
ʻElima mau ʻano nui o nā plastics maʻamau maʻamau: PE (Polyethylene), PP (Polypropylene), PVC (Polyvinyl chloride), PS (Polystyrene) a me ABS (Acrylonitrile-butadiene-styrene Copolymer), PVC a me ABS i hoʻohana pinepine ʻia i loko. nā mea pāʻani lole.
A ua ʻike mākou ua hoʻohana kekahi mea hoʻolālā i nā mea "resin", a ʻo ka hapa nui o lākou he PU resin (Polyuracet), he aha ka Polyurethane?
ʻO ka resin PU (polyurethane) he pūhui polymer organik e puka mai nei, i kapa ʻia ʻo ke ono o ka plastic plastic.
PVC
Hele mai ʻo PVC i ʻelua ʻano kumu: paʻa a maʻalahi. ʻO nā ʻano paʻa i ke ola e like me nā paipu wai, nā kāleka panakō, a me nā mea ʻē aʻe; ʻoi aku ka palupalu a ʻoi aku ka palupalu o nā huahana ma o ka hoʻohui ʻana i nā plasticizers, e like me nā raincoats, nā kiʻiʻoniʻoni plastik, nā huahana inflatable, etc.
ʻO ka PVC a me ka vinyl i hoʻohana pinepineʻia i nā kiʻi PVC kaulana i hana maoliʻia me PVC (polyvinyl chloride), akā heʻokoʻa nā kaʻina hana. ʻO ka PVC maʻamau e pili ana i ke kaʻina hana injection, a ʻo "vinyl" kahi hana hana PVC kūikawā e hui pū ai i ka wai me ka "glue". (hoʻopili ʻia ka hopena PVC) ua uhi like ʻia ma ka paia o loko o ka poʻi ma o ka hoʻololi ʻana i ka centrifugal.
ABS
Hoʻokumu ʻia ʻo ABS me Acrylonitrile (PAN), Butadiene (PB), a me Styrene (PS) he copolymer o ʻekolu mau ʻāpana, kahi e hui pū ai i nā pono hana o nā ʻāpana ʻekolu. He mea "paʻakikī, paʻakikī a paʻakikī" me ka maʻalahi o ka loaʻa ʻana o nā mea maka, ke kumu kūʻai haʻahaʻa, ka hana maikaʻi a me ka laulā o nā mea hoʻohana. Loaʻa iā ia ke kūpaʻa wela a me ke anu.
He mea maʻalahi loa ka hana ABS. Hiki ke hana ʻia e nā ʻano hana like ʻole e like me ka injection, extrusion, a me ka thermoforming; hiki ke hana ia ma ka ʻili ʻana, ka ʻeli ʻana, ka waiho ʻana, ka wili ʻana, etc.; hiki ke hoʻopaʻa ʻia me nā mea hoʻoheheʻe organik e like me ka chloroform; hiki ke hoʻopuʻi ʻia, waihoʻoluʻu, electroplated, a me nā lāʻau lapaʻau ʻē aʻe.
I ka ʻoihana pāʻani, ʻo ka hiʻohiʻona kaulana loa o ka noi ABS ʻo LEGO.
