He aha nā granules PVC?

ʻO PVC kekahi o nā plastik i hoʻohana nui ʻia ma ka ʻoihana ʻoihana. ʻO Plasticol, kahi hui Italia kokoke i Varese, ua hana ʻo ia i nā granules PVC no nā makahiki he 50 a ʻoi aku i kēia manawa a ʻo ka ʻike i hōʻiliʻili ʻia i nā makahiki i hala aku nei ua hiki i ka ʻoihana ke loaʻa kahi pae hohonu o ka ʻike e hiki ai iā mākou ke hoʻohana iā ia e hoʻokō i nā noi a nā mea kūʻai aku e hāʻawi ana i nā huahana hou a hilinaʻi.

ʻO ka ʻoiaʻiʻo ua hoʻohana nui ʻia ʻo PVC no ka hana ʻana i nā mea like ʻole e hōʻike ana i ke ʻano o kona mau ʻano kūloko he mea pono loa a kūikawā. E hoʻomaka kākou e kamaʻilio e pili ana i ka paʻakikī o PVC: he paʻakikī loa ka mea inā maʻemaʻe akā lilo ia i mea palupalu inā hui pū ʻia me nā mea ʻē aʻe. ʻO kēia ʻano kūikawā e kūpono ai ʻo PVC no ka hana ʻana i nā huahana i hoʻohana ʻia ma nā ʻano like ʻole, mai ke kūkulu ʻana a hiki i ka mea kaʻa.

Eia naʻe, ʻaʻole kūpono kēlā me kēia ʻano o ka mea. He haʻahaʻa loa ka mahana hoʻoheheʻe o kēia polymer, ʻo ia hoʻi ka mea kūpono ʻole ai ʻo PVC no kēlā mau wahi kahi e hiki ai ke hiki i nā mahana kiʻekiʻe loa.

Eia kekahi, hiki i nā pōʻino ke puka mai ka ʻoiaʻiʻo, inā wela loa, hoʻokuʻu ʻo PVC i nā molekala o ka chlorine ma ke ʻano he hydrochloric acid a i ʻole dioxin. ʻO ka hoʻopili ʻana me kēia mea hiki ke hoʻoulu i nā pilikia olakino hiki ʻole ke hoʻoponopono ʻia.

I mea e kūpono ai ka polymer me kāna hana ʻoihana, ua hui pū ʻia me nā mea hoʻopaʻa, nā plasticisers, nā mea hoʻoluʻu, a me nā lubricants e kōkua ana i ke kaʻina hana a me ka hoʻolilo ʻana i ka PVC i ʻoi aku ka palupalu a me ka emi ʻana o ka maʻalahi o ke komo ʻana a me ka haehae ʻana.

Ma muli o kona mau ʻano a me kona pōʻino, pono e hana ʻia nā granules PVC i nā hale hana kūikawā. Loaʻa iā Plasticol kahi laina hana i hoʻolaʻa wale ʻia no kēia mea plastik.

ʻO ke kahua mua o ka hana ʻana i nā granules PVC ʻo ia ka hana ʻana i nā paipu lōʻihi o nā mea i hana ʻia ma o kahi hale hana extrusion kūikawā. ʻO ka hana aʻe, ʻo ia ka ʻoki ʻana i ka plastic i loko o nā momi liʻiliʻi loa. He maʻalahi maoli ke kaʻina hana, akā he mea nui loa ia e akahele i ka wā e lawelawe ai i ka mea, e lawe ana i nā hana palekana koʻikoʻi e hiki ai ke paʻakikī.
