Loaʻa i ka pepa PVC ka formaldehyde?

ʻAʻohe formaldehyde ka papa PVC, akā no nā huahana PVC maʻamau wale nō kēia, a ʻaʻole hiki ke hōʻoia ʻia kekahi mau huahana hoʻopunipuni a haʻahaʻa. I kēia mau lā, nui nā huahana PVC ma ka mākeke e hoʻohana i nā stabilizer paʻakai alakaʻi, a ʻo kēia stabilization he mea pōʻino a pōʻino i ke kino kanaka. No laila, i ke koho ʻana i nā huahana, pono ʻoe e koho i nā huahana kūlohelohe, a pono ʻoe e kūʻai iā lākou ma nā hale kūʻai maʻamau.

ʻO ka papa PVC ka hapa nui loa i ka ʻoihana hale kūkulu, ma 60%, ukali ʻia e ka ʻoihana paʻi, a aia kekahi mau noi liʻiliʻi liʻiliʻi. E like me ke kiʻekiʻe o ka palupalu a me ka paʻakikī, hiki ke hoʻokaʻawale ʻia i PVC palupalu a me PVC paʻakikī. E like me ke kaʻina hana, hiki ke hoʻokaʻawale ʻia i loko o ka papa ʻili ʻili PVC a me ka papa ʻaina manuahi PVC. Wahi a ke aniani a me ka opaque, hiki ke hoʻokaʻawale ʻia i ka PVC transparent board a me ka pvc board.

ʻO ka PVC foam board nā hiʻohiʻona o ka anti-corrosion, moisture-proof, mildew-proof, non-absorbent, drillable, sawable, planable, maʻalahi i ka thermoform, wela bending processing, etc., no laila ua hoʻohana nui ʻia i nā lako, nā keʻena, nā keʻena ʻauʻau, nā papa hōʻikeʻike, pahu pahu kumu, nā mea hoʻonani hale a me waho, nā mea kūkulu hale, nā mea hana kemika a me nā kula ʻē aʻe. ʻeke huahana a me nā ʻoihana ʻē aʻe.

ʻO ka PVC paʻa paʻa paʻa paʻa i ka corrosion kū'ē, insulation, a me kekahi ikaika mechanical; ma hope o ka hana lua, hiki ke hana ʻia i loko o ka sulfuric acid (hydrochloric acid) tank (pahu pahu); paʻa nila no ka lāʻau lapaʻau, paʻa kaʻina hana kemika; pahu wai halepaku lehulehu; nā huahana kūikawā like ʻole a me nā ipu e like me nā templates, panel decorative, exhaust ducts, linings lako, etc. o nā huahana i hana ʻia. He mea kūpono ia no ka kemika, nā mea kūkulu hale, nā mea hoʻonaninani a me nā ʻoihana ʻē aʻe.
