1. He aha ka Rigid PVC pepa?
ʻO ka inoa piha o ka pepa paʻa PVC he polyvinyl chloride rigid sheet. ʻO ka pepa PVC paʻa he mea polymer i hana ʻia me ka vinyl chloride e like me ka mea maka, me nā stabilizers, lubricants a me nā mea hoʻopiha i hoʻohui ʻia. Loaʻa iā ia ka antioxidant super kiʻekiʻe, ka waika ikaika a me ka hoʻohaʻahaʻa kūʻē, ka ikaika kiʻekiʻe, ka paʻa maikaʻi loa a me ka hiki ʻole ke hoʻopau ʻia, a hiki ke pale aku i ka corrosion i hana ʻia e ka hoʻololi ʻana i ke aniau. ʻO nā pāpaʻi paʻa PVC maʻamau e pili ana i nā ʻāpana PVC akaka, nā ʻāpana PVC keʻokeʻo, nā ʻāpana PVC ʻeleʻele, nā ʻāpana PVC kala, nā ʻāpana PVC hina, etc.
2. He aha ka pono o Rigid PVC pepa?
He nui nā pono e like me ka pale ʻana i ka corrosion, non-flammability, insulation, a me ka pale oxidation. Eia hou, hiki iā lākou ke hana hou a loaʻa nā kumukūʻai hana haʻahaʻa. Ma muli o ko lākou ākea ākea a me nā kumukūʻai kūpono, ua noho mau lākou i kahi ʻāpana o ka mākeke pepa plastic. I kēia manawa, ua hōʻea ka hoʻomaikaʻi ʻana o kā mākou ʻāina a me ka ʻenehana hoʻolālā o nā pepa PVC i ka pae kiʻekiʻe o ka honua.
3. He aha ka hoʻohana ʻana i ka pepa PVC?
ʻO nā pepa PVC he mea maʻalahi loa, a aia nāʻano likeʻole o nā pepa PVC, e like me nā pepa PVC akaka, nā pepa PVC hau, nā pepa PVC'ōmaʻomaʻo, nā'ōwili pepa PVC, a me nā mea'ē aʻe. Hoʻohana nui ʻia nā pepa PVC a hoʻohana nui ʻia e hana: nā uhi paʻa PVC, nā kāleka PVC, nā kiʻi ʻoniʻoni PVC paʻakikī, nā pepa PVC paʻakikī, etc.
4. He aha ka hemahema o ka pepa PVC?
ʻO ka pepa PVC kekahi i hoʻohana pinepine ʻia. He resin i haku ʻia me ka resin polyvinyl chloride, plasticizer, a me ka antioxidant. ʻAʻole ia he mea ʻawaʻawa iā ia iho. Akā ʻo nā mea kōkua nui e like me nā plasticizers a me nā antioxidants he mea make. Hoʻohana nui nā plasticizers i kēlā me kēia lā PVC sheet plastics dibutyl terephthalate a me dioctyl phthalate. He mea ʻawaʻawa kēia mau mea kemika. ʻO ka antioxidant lead stearate i hoʻohana ʻia ma PVC he mea ʻawaʻawa nō hoʻi. ʻO nā pāpaʻi PVC i loaʻa nā antioxidants paʻakai kēpau e hoʻoheheʻe i ke alakaʻi i ka wā e hui ai lākou me nā mea hoʻoheheʻe e like me ka ethanol a me ka etera. Hoʻohana ʻia nā pāpaʻi PVC me ke kēpau no ka hoʻopili ʻana i nā meaʻai. Ke hālāwai lākou me nā lāʻau palaoa palai, nā keke palai, nā iʻa palai, nā meaʻai i hoʻomoʻa ʻia, nā pāpaʻi a me nā mea ʻai, a me nā mea ʻē aʻe, e laha ʻia nā molekole kēpau i loko o ka ʻaila. No laila, ʻaʻole hiki ke hoʻohana ʻia nā ʻeke pepa PVC e paʻa i ka meaʻai, ʻoi aku ka meaʻai i loko o ka aila. Eia kekahi, ʻo nā huahana plastik polyvinyl chloride e hoʻoheheʻe lohi i ke kinoea hydrogen chloride i nā mahana kiʻekiʻe, e like me ka 50 ° C, he mea pōʻino i ke kino kanaka.
