He aha nā ʻokoʻa ma waena o ka ʻili PU a me ka ʻili PVC?

Me ka hoʻomohala ʻana o ka ʻepekema a me ka ʻenehana, ua hoʻomaikaʻi maikaʻi ʻia ka ʻenehana hana a me ke kaʻina hana o ka ʻili synthetic maka i nā makahiki i hala.Hoʻohana nui ʻia nā mea ʻili synthetic i ka hana ʻana i nā ʻeke, a me nā ʻeke PVC a me PU i ka ʻili synthetic i makemake nui ʻia e nā mea kūʻai aku!Akā e like me nā mea kūʻai maʻamau, ʻaʻole ʻike ka poʻe he nui i ka ʻokoʻa ma waena o PVC a me PU,

1. Hoʻokaʻawale ʻia ka uhi ʻana o ka polyurethane PU i loko o ka ʻeke i ka uhi keʻokeʻo keʻokeʻo PU a me ka uhi kala kala PU.ʻO nā waiwai kumu o ka PU keʻokeʻo keʻokeʻo a me ke kala kala e like me nā mea o ka uhi ʻana i ka PA, akā ʻo ka PU keʻokeʻo keʻokeʻo a me ke kala kala i piha i ka lima lima, ʻoi aku ka lole elastic a ʻoi aku ka wikiwiki, a ʻo ka uhi kala kala PU hiki ke kū i ka wai kiʻekiʻe. puʻe, a me ka uhi PU he moisture permeability, ventilation, aahu kū'ē, a me nā mea'ē aʻe, akā, ua kiʻekiʻe ke kumu kūʻai a me ke aniau kū'ēʻilihune.

2. Hoʻohālikelike ʻia me ka uhi ʻana o PU, ʻoi aku ka lahilahi o ka lole lalo o ka uhi PVC.Eia naʻe, ʻaʻole ʻona wale ke kiʻi o ka uhi PVC, akā maʻalahi hoʻi i ka makahiki.ʻO ka mea nui aku, ʻaʻole maikaʻi ka paʻa o ka uhi PVC e like me ka uhi ʻana o PU, a paʻakikī hoʻi ka lole.Inā hoʻohana ʻoe i ke ahi, ʻoi aku ka nui o ka ʻono o ka lole uhi PVC ma mua o ka lole uhi PU.

3. Ma waho aʻe o ka ʻokoʻa ma waena o ka PU a me ka PVC i uhi ʻia i nā lole i loko o nā ʻeke i ka lima a me ka ʻono, ʻo kekahi mea ʻo ka uhi ʻana o PU he ʻili maʻamau, ʻoiai ʻo PVC ke kāpili.

4. ʻOi aku ka paʻakikī o ka hana ʻana o ka ʻili PU ma mua o ka ʻili PVC.ʻOiai ʻo ka lole base PU he mea canvas PU me ka ikaika tensile maikaʻi, hiki ke uhi ʻia ma luna o ka lole kumu a hoʻokomo pū ʻia i waena, ʻaʻole hiki ke ʻike i ke ola o ka lole kumu.

5. ʻOi aku ka maikaʻi o ke kino o ka ʻili PU ma mua o ka ʻili PVC, me ke kūʻē maikaʻi i ka flexure, palupalu, ikaika tensile a me ka ea permeability (PVC ʻaʻohe).ʻO ke ʻano o ka ʻili PVC ua paʻi wela ʻia e ka ʻili kila.Hoʻopili wela ke kumu o ka ʻili PU ma ka ʻili o ka ʻili semi-finished me kahi ʻano pepa kumu.Ma hope o ka hoʻoluʻu ʻana, hoʻokaʻawale ʻia ka ʻili pepa no ka mālama ʻana i ka ʻili.ʻOi aku ke kumukūʻai o ka ʻili PU ma mua o ʻelua o ka ʻili PVC, a ʻo ke kumukūʻai o ka ʻili PU me nā koi kūikawā he 2-3 mau manawa kiʻekiʻe ma mua o ka ʻili PVC.ʻO ka mea maʻamau, hiki ke hoʻohana ʻia ka pepa maʻamau no ka ʻili PU i 4-5 mau manawa, a laila e ʻoki ʻia.ʻOi aku ka lōʻihi o ka hoʻohana ʻana o ka roller pattern, no laila ʻoi aku ka kiʻekiʻe o ke kumukūʻai o ka ʻili PU ma mua o ka ʻili PVC.

Ma kēia ala, ʻoiai mākou e hoʻomaopopo i nā ʻano ma waena o nā mea ʻelua, e ʻoi aku ka maʻalahi o nā mea kūʻai aku ʻaʻole ʻoihana e ʻike inā he PU a PVC paha nā ʻeke, ʻoiai mākou e hoʻokaʻawale iā lākou mai nā helu ʻekolu: ʻo ka manaʻo. He palupalu a elastic, ʻoiai ʻaʻole maikaʻi ka manaʻo inā paʻakikī ʻo PVC.ʻO ka lua, e nānā i ka lole lalo.ʻOi aku ka mānoanoa o ka lole lalo o ka PU a ʻoi aku ka lahilahi o ka ʻili plastik, a ʻoi aku ka lahilahi o ka PVC.ʻO ke kolu ke ahi.E maʻalahi ka ʻono pu ma hope o ke puhi ʻana.

Ma muli o ka mea i luna aʻe, hiki iā mākou ke huki i kahi hopena: ʻoi aku ka maikaʻi o ka hana o ka ʻili PU ma mua o ka ʻili PVC, a ʻoi aku ka maikaʻi o nā ʻeke PU ma mua o nā ʻeke PVC!
