ʻO nā hiʻohiʻona o nā mea pu, ka ʻokoʻa ma waena o nā mea pu, ka ʻili pu a me ka ʻili maoli, ʻo ka lole PU he lole ʻili simulated, synthesized mai nā mea hana, me ke ʻano o ka ʻili maoli, ikaika loa a paʻa, a me ke kumukūʻai. 'Ōlelo pinepine ka poʻe i ka ʻili PU he ʻano mea ʻili, e like me ka ʻili PVC, ka pepa ʻili ʻili Italia, ka ʻili recycled, a me nā mea ʻē aʻe. Ma muli o ka ikaika tensile maikaʻi o ka lole base PU, ma waho aʻe o ka uhi ʻia ʻana i ka lole kumu, hiki ke hoʻokomo pū ʻia ka lole kumu i loko, i ʻike ʻole ʻia ke ola o ka lole kumu ma waho.
Nā hiʻohiʻona o nā mea pu
1. ʻO nā waiwai kino maikaʻi, kū'ē i nā wili a me ka huliʻana, ka palupalu maikaʻi, ka ikaika tensile kiʻekiʻe, a me ka hanu. Hoʻopili mua ʻia ke ʻano o ka lole PU ma ka ʻili o ka ʻili semi-finished me kahi pepa i hoʻohālikelike ʻia, a laila hoʻokaʻawale ʻia ka ʻili pepa a mālama ʻia ka ʻili ma hope o ke anuanu.
2. ʻO ke kūlana kiʻekiʻe o ka ea, hiki i ka wela wela ke hiki i ka 8000-14000g / 24h / cm2, ka ikaika peeling kiʻekiʻe, ke kūpaʻa wai kiʻekiʻe, he mea kūpono ia no ka ʻili a me ka papa lalo o nā lole lole wai a me ka hanu.
3. Kumukuai kiekie. ʻO ke kumukūʻai o kekahi mau lole PU me nā koi kūikawā he 2-3 mau manawa kiʻekiʻe ma mua o nā lole PVC. Hiki ke hoʻohana ʻia ka pepa kumu no nā lole PU maʻamau i 4-5 mau manawa ma mua o ka ʻoki ʻia ʻana;
4. He lōʻihi ke ola lawelawe o ka roller pattern, no laila ʻoi aku ka kiʻekiʻe o ke kumukūʻai o ka ʻili PU ma mua o ka ʻili PVC.
ʻO ka ʻokoʻa ma waena o ka mea PU, ka ʻili PU a me ka ʻili maoli:
1. Aʻala:
ʻAʻohe ʻala o ka ʻili PU, ʻo ka ʻala wale nō o ka plastic. Eia naʻe, ʻokoʻa ka ʻili holoholona maoli. He ʻala huluhulu ikaika kona, ʻoiai ma hope o ka hana ʻana, e loaʻa iā ia kahi ʻala ikaika.
2. E nana i na pores
Hiki i ka ʻili maoli ke ʻike i nā hiʻohiʻona a i ʻole nā pores, a hiki iā ʻoe ke hoʻohana i kou mau manamana lima e ʻoki ai a ʻike i nā kaula holoholona i kūkulu ʻia. ʻAʻole hiki i nā huahana ʻili Pu ke ʻike i nā pores a i ʻole nā hiʻohiʻona. Inā ʻike ʻoe i nā hiʻohiʻona o ke kālai kiʻi ʻia, he mea PU ia, no laila hiki iā mākou ke hoʻokaʻawale iā ia ma ka nānā ʻana.
3. Hoopa aku me kou mau lima
Maikaʻi loa ka ʻili maoli a elastic. Eia naʻe, ʻilihune ka manaʻo o ka ʻili PU. Manaʻo ia e like me ka hoʻopā ʻana i ka plastic a me ka elasticity maikaʻi loa. No laila, hiki ke hoʻokolokolo ʻia ka ʻili maoli a me ka hoʻopunipuni ma ke kulou ʻana i ka huahana ʻili.
