Ua hiki mai ke kauwela, pehea ka pale ʻana o ka pale puka palupalu PVC i ka ʻelemakule?

Ke piʻi nei ka wela a me ka wela, a kokoke i ke kauwela, a ua komo nā kaikamahine i ka pale lā e pale i ko lākou ʻili mai nā kukuna ʻino o ka lā.Pēlā nō, no ka hapa nui o nā mea hana, pono e hoʻomākaukau no ka lā ua, ma kā lākou huahana ponoʻī e pale aku, e like me kā lākou iho, i kēia lā ke kamaʻilio nei mākou e pili ana i ka pale ʻana i ka pale palupalu.ʻO ka pale puka PVC palupalu kahi huahana e ʻike ʻia e nā mea āpau ma nā wahi āpau.Me ka hoʻomohala ʻana o ka lehulehu, ua ʻike ʻia nā ʻano ʻano pale puka PVC aniani, e like me: ka malu o ka puka plastik PVC aniani, ka malu o ka puka aniani, ka pale pale lepo lepo, ka pale puka anti-static, ka malu puka pale anuanu, haʻahaʻa. ka malu puka pale wela, ka malu puka aniani anti-ultraviolet, ka papa palupalu PVC alohilohi, ka puka owili awiwi, ka puka owili wikiwiki, ka malu puka pale lepo PVC, ka malu pulu pahee PVC, ka malu puka palupalu akaka, ka malu pale pale pale, ʻO ka malu o ka pāpaʻi PVC, ka malu puka puka PVC, ka malu puka aniani, etc.ʻO ka pale puka palupalu palupalu i hana ʻia me ka PVC mālama i ke anu, mālama i ka mahana, mālama i ka ikehu a hoʻopaʻa i ke ea anu a me ka wela.Insect, lepo, makani, mākū, ahi, uila paʻa, anti-glare, anti-uv, hoʻokaʻawale leo, ke ao, ka ʻōlelo aʻo palekana, pale i nā pōʻino.E pili ana i ka mālama anu, ka meaʻai, kemika, lāʻau lapaʻau, textile, electronics, machinery, paʻi, hale hana, hale hoʻokipa, halemai, mākeke, hale ʻaina a me nā ʻoihana ʻē aʻe ma kēlā me kēia wahi.Hiki iā ʻoe ke ʻōlelo he ākea ākea o nā noi.

No laila pehea mākou e mālama ai i ka pale puka mai ka melemele a me ka wehe ʻana no ka manawa lōʻihi?Pono kākou e ʻike i ke kumu o kona melemele ʻana.Ke hōʻike nei nā noiʻi ʻo ka ʻelemakule o nā polymers i loko o ka lewa e pili ana i ka degradation photooxidation o nā polymers e ka radiation ultraviolet a me ke komo ʻana o ka oxygen, pvc Curtain, uea a me ke kaula, nā kiʻi ʻoniʻoni a me nā huahana waho ʻē aʻe e uku nui aku.Wahi a ka quantum mechanics, ʻo ka ikehu o ka photon hoʻokahi i hoʻohālikelike ʻia me ka lōʻihi o ka nalu, a ʻo ka pōkole o ka nalu, ʻoi aku ka kiʻekiʻe o ka ikehu.ʻOiai ʻo ka ikaika o ka hihi ultraviolet he 5% wale nō o ka lā, ʻo kona lōʻihi hawewe ka pōkole loa, a ʻo ka ikehu photon hoʻokahi ka mea kiʻekiʻe loa, ma kahi o 290 ~ 390 KJ/MOL.ʻO ka ikehu paʻa o ka hui he 290 ~ 400 Kj / mol, kahi kokoke i ka ikehu o ka hihi ultraviolet a hiki ke hoʻopau ʻia e ka hihi ultraviolet, ʻo ia ke kumu nui o ka pale PVC maʻalahi e hana photoaging.I ka wā o ka ʻelemakule, hoʻopuka ʻia ka radical manuahi a me ka hydroperoxide, haki ʻia ke kaulahao macromolecule a hoʻopaʻa ʻia, a ma hope ua nalowale ka huahana i kāna hana.

Hiki i ka UV Absorber ke pale pono i ka pōʻino o UV i nā huahana, i mea e hōʻemi ai i ka deterioration o ka huahana a hoʻonui i ke ola lawelawe o nā polymers.Hiki i kahi LR-ZW-1 i hoʻomohala ʻia e Henan Longrui Chemical Co., Ltd. hiki ke hoʻopaʻa ikaika i ka 270 ~ 400nm UV, hoʻokuʻu ʻia ka ikehu i hoʻopau ʻia e like me ka ikehu wela a i ʻole ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, i mea e pale ai i ka ikehu UV i komo ʻia e ka Chromophore o ka pale PVC mai ka hauʻoli.Hoʻonui i ke ola lawelawe o ka pale, ʻaʻole maʻalahi ka melemele ʻana, ʻaʻole hoʻi e pili i ka ʻike, ʻo ka mea nui ka hoʻohui ʻana i kahi liʻiliʻi, e mālama i ke kumukūʻai o nā mea hana.
