He aha nā granules PVC?

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

ʻO ka ʻoiaʻiʻo e hoʻohana nui ʻia ʻo PVC no ka hana ʻana i nā mea like ʻole e hōʻike ana i ke ʻano o kāna mau hiʻohiʻona intrinsic i mea pono loa a kūikawā. E hoʻomaka kākou e kamaʻilio e pili ana i ka paʻa o PVC: ʻoʻoleʻa loa ka mea inā maʻemaʻe akā hiki ke maʻalahi inā hui pū me nā mea ʻē aʻe. ʻO kēia ʻano kūʻokoʻa e kūpono ai ka PVC no ka hana ʻana i nā huahana i hoʻohana ʻia ma nā ʻano ʻokoʻa like ʻole, mai ke kūkulu hale a hiki i ke kaʻa.

Eia naʻe, ʻaʻole maʻalahi kēlā me kēia ʻano o ka waiwai. He haʻahaʻa loa ka wela hoʻoheheʻe ʻana o kēia polymer, kahi i kūpono ʻole ai ka PVC no kēlā mau wahi kahi e hiki ai ke kiʻekiʻe kiʻekiʻe.

Eia kekahi, hiki i nā pōʻino ke hoʻomaka mai ka ʻoiaʻiʻo, inā wela loa, hoʻokuʻu ʻo PVC i nā molekala o ka chlorine e like me ka waika hydrochloric a i ʻole dioxin. Hiki ke hoʻopili i kēia mea i nā pilikia olakino hiki ʻole ke hoʻoponopono ʻia.

No ka hoʻohālikelike ʻana i ka polymer me kāna hana ʻoihana, ua hui pū ʻia me nā stabilisers, plasticisers, colorants, a me nā lubricants e kōkua i ke kaʻina hana a me ka hana ʻana i ka PVC i ʻoi aku ka maʻalahi a me ka liʻiliʻi o ka lole a me ka waimaka.

Ma muli o kona mau hiʻohiʻona a me kona pōʻino, pono e hana ʻia nā granule PVC i nā mea kanu kūikawā. Loaʻa iā Plasticol kahi laina hana i hoʻolaʻa wale ʻia i kēia mea plastic.

ʻO ka hana mua o ka hana ʻana i nā granules PVC ʻo ia ka hana ʻana o nā paipu lōʻihi o nā mea i hana ʻia ma o kahi mea kanu extrusion kūikawā. ʻO ka ʻanuʻu aʻe, ʻo ia ka ʻoki ʻana i ka plastik i loko o nā pahu liʻiliʻi maoli. He mea maʻalahi loa ke kaʻina hana, akā he mea nui loa ka hoʻohana ʻana i ka makaʻala i ka wā e lawelawe ai i ka mea, e mālama i nā ʻano kumu e paʻakikī ai.
