ʻO ka hoʻolauna ʻana i nā ʻano mea palaki PVC a me nā kala maʻamau

Ma muli o nā waiwai kupaianaha o PVC plastic, ua hoʻohana ʻia i nā wahi he nui o ke ola. A ʻo kēia mau pepa PVC, he mau huahana maʻamau. Hoʻohui ia i kekahi mau kala i loko o ke kaʻina hana e hana i nā huahana i ʻoi aku ka nani. Akā ʻaʻole ʻike nui kekahi poʻe e pili ana i kēia, i kēia lā e hōʻike kikoʻī kēia ʻatikala.

ʻO ka resin PVC kahi thermoplastic me nā hale i wehewehe ʻole ʻia. ʻO ka wahi palupalu o ka resin kokoke i ka mahana decomposition. Ua hoʻomaka e decompose ma 140 ℃, a ʻoi aku ka wikiwiki ma 170 ℃. Ma muli o kāna ʻike o nā ʻātoma chloride, ʻo ka molekele polyethylene a me kāna mau copolymers ka mea maʻamau i ka lapalapa ahi me ka hoʻopau ponoʻī a me nā waiwai hāʻule ʻole. He polymer paʻa ʻole ia i hoʻohaʻahaʻa ʻia e ka māmā a me ka wela. Loaʻa iā ia ka ikehu kūpaʻa kemika maikaʻi loa, a he waiwai nui ia e like me kahi mea anticorrosion. He kūpaʻa ka PVC no ka hapa nui o nā waikawa inorganic a me nā kumu a ua māhele ʻia no ka hydrogen chloride. Hiki ke hoʻoheheʻe ʻia i nā ketones a me nā mea hoʻoheheʻe ʻala.

ʻO nā waihoʻoluʻu i hoʻohana ʻia no nā plastik PVC ka nui o nā puaʻa kūlohelohe a me nā mea ʻole. He kiʻekiʻe ko PVC plastics no ka puaʻa, e like me ke kiʻekiʻe wela ke kū'ē i ka wā o ka hanaʻana,ʻaʻohe neʻe i ka hanaʻana, ka pale māmā, a me nā mea'ē aʻe. ʻulaʻula phthalocyanine, etc. 2, melemele nui chromium melemele, cadmium melemele a fluorescent melemele; 3, orchid kala nui phthalocyanine uliuli; 4, ʻōmaʻomaʻo nui ka phthalocyanine ʻōmaʻomaʻo; 5, hoʻohana nui ke keʻokeʻo i ka titanium dioxide; 6, ʻo ka poni ka nui o ka poni plastik; 7, ʻeleʻele ka nui kalapona ʻeleʻele. Eia kekahi, hoʻohana ʻia ka mea hana keʻokeʻo fluorescent no ka hoʻomaʻemaʻe; hoʻohana ʻia ka pauda gula a me ke kālā no ka paʻi kala; a me ka pauka astigmatism i ka plastik e like me ka momi.
