He aha ka ʻili PU? Pehea mākou e hoʻokaʻawale ai i ka ʻili PU mai ka ʻili maoli?

?ʻO ka ʻili PU he mea synthetic i hana ʻia e ke kanaka. He ʻili hana maʻamau ka hiʻohiʻona a me ke ʻano o ka ʻili maoli, akā ʻoi aku ka liʻiliʻi, ʻaʻole lōʻihi, a loaʻa paha nā kemika. ?
ʻAʻole ʻili maoli ka ʻili PU. ʻO ka ʻili PU he ʻano ʻili hana. Hana ʻia ia me nā mea fiber kemika, aʻo ka ʻili maoli i hana ʻia a hana ʻia mai ka ʻili holoholona. ʻO ka ʻili maoli i ʻōlelo ʻia ma ka mākeke ʻo ia ka papa mua o ka ʻili a me ka papa lua o ka ʻili.
ʻO ka ʻili PU, ʻo ka inoa piha o ka ʻili polyurethane, he mea synthetic i hana ʻia e ka hoʻopili ʻana i ka uhi polymer synthetic ma ka ʻili o nā fila holoholona. Hoʻokomo pinepine kēia mau uhi i ka polyurethane. Loaʻa i ka ʻili PU ke kūpaʻa maikaʻi loa, ka hanu, ke kūpaʻa ʻelemakule a me ka maʻalahi. Ua like ka hopena o ka helehelena me ka ʻili maoli, a ʻoi aku ka maikaʻi ma mua o ka ʻili maoli i kekahi mau waiwai kino. Eia naʻe, ke hoʻohālikelike ʻia me ka ʻili maoli, ʻokoʻa ka ʻili PU i ka lōʻihi, ka mālama ʻana a me ka pale ʻana i ke kaiapuni.
Pehea i hana ʻia ai ka ʻili PU? ʻO ka inoa piha o ka ʻili PU he ʻili polyurethane. Hana ʻia ia ma ka hoʻopili ʻana i ka resin polyurethane ma ka lole a i ʻole ka lole i ulana ʻole ʻia, a laila e hana i nā kaʻina hana e like me ka hoʻomehana ʻana a me ka embossing e loaʻa ai nā kala like ʻole, nā ʻano a me nā mānoanoa. Hiki i ka ʻili PU ke hoʻohālike i ke ʻano a me ka manaʻo o nā ʻili maoli like ʻole, e like me ka ʻili bipi, ka ʻili hipa, ka ʻili puaʻa, etc.

He aha nā mea maikaʻi o ka ʻili PU? ʻO ka mea mua, he māmā ka ʻili PU a ʻaʻole e kaumaha i nā wāwae. ʻO ka lua, ʻoi aku ka paʻa o ka ʻili PU a ʻaʻole maʻalahi ke ʻoki ʻia a ʻeha paha. ʻO ke kolu, ʻoi aku ka maʻalahi o ka hoʻomaʻemaʻe ʻana i ka ʻili PU, e holoi wale me kahi lole pulu. ʻO ka mea hope loa, ʻoi aku ka maikaʻi o ka ʻili PU a ʻaʻole ia e hōʻeha i nā holoholona.

No laila, he aha nā hemahema o ka ʻili PU? ʻO ka mea mua, ʻaʻole hanu ka ʻili PU, kahi e hoʻomaha ai nā wāwae a pilau maʻalahi. ʻO ka lua, ʻaʻole kūpaʻa ka ʻili PU i nā wela kiʻekiʻe a hiki i ka deformation a i ʻole ka ʻelemakule. ʻO ke kolu, ʻaʻole palupalu a ʻoluʻolu ka ʻili PU, a ʻaʻohe elasticity a kūpono i ka ʻili maoli. ʻO ka mea hope loa, ʻaʻole kiʻekiʻe ka ʻili PU a ʻaʻole lawa ka ʻili a me ke ʻano o ka ʻili maoli.
‌ʻO nā ʻano e hoʻokaʻawale ai i ka ʻili PU mai ka ʻili maoli:

‌Source a me nā mea hoʻohui ʻO ka ʻili PU he ʻili kūlohelohe, me ka polyurethane resin ma ke ʻano nui, i hana ʻia e ka hopena kemika, me ke kūpaʻa maikaʻi ʻana, ka pale ʻana a me ke kūpaʻa ʻelemakule.
ʻO ka hiʻohiʻona a me ka hoʻopā: Hāʻawi ka ʻili maoli i kahi paʻi kūlohelohe a me kahi ʻano kūlohelohe kūʻokoʻa. ʻOiai hiki i ka ʻili PU ke hoʻohālike i ke ʻano a me ka hoʻopā ʻana o ka ʻili maoli, ʻike mau ʻia ke ʻano maoli. ʻO ka ʻili maoli nā laina akaka loa, a ʻokoʻa kēlā me kēia ʻāpana. ʻO nā laina o ka ʻili PU ua ʻoi aku ka pohō a me ka monotonous. Manaʻo ka ʻili maoli i ka palupalu a me ka elastic, palupalu a maʻalahi. Nawaliwali ka ʻili PU a me kahi astringent liʻiliʻi.

‌Ka lōʻihi‌: ʻOi aku ka lōʻihi o ka ʻili maoli, ʻoi aku ka paʻakikī a me ka elasticity, a hiki ke pale i ka hopena o waho a me ka friction. ʻOiai he kūpaʻa maikaʻi ka ʻili PU, hiki iā ia ke ʻike i ka ʻelemakule, ka haki a me nā pilikia ʻē aʻe ma hope o ka hoʻohana lōʻihi.
‌Maintenance a mālama‌: Pono ka ʻili maoli i ka mālama mau a me ka mālama ʻana, a hoʻohana ʻia nā mea mālama ʻili kūikawā no ka hoʻomaʻemaʻe, hoʻomaʻemaʻe a me ka wai. He mea maʻalahi ka mālama ʻana i ka ʻili PU, holoi wale me kahi lole pulu.
‌Ka palekana o ke kaiapuni‌: Mai ka ʻili holoholona mai ka ʻili maoli, a he liʻiliʻi nā ʻōpala a me ka haumia i kāna kaʻina hana. Ma ke ʻano he ʻili hana, hiki i ka ʻili PU ke hoʻohaumia i ke kaiapuni i kāna kaʻina hana.
E pili ana i ka ʻala: He ʻala ʻili maʻamau ka ʻili maoli, a lilo ia i mea ʻala i ka hala ʻana o ka manawa. E ʻoi aku ka ikaika o ka ʻili ʻili PU. E emi a honi ka ʻili maoli e like me ka lauoho ʻā i ka wā e hālāwai ai me ka lapalapa. E hehee a honi ka ʻili PU e like me ka ʻilika ʻā i ka wā e hālāwai ai me nā lapalapa.
Hoʻohana no nā manawa like ʻole

ʻAʻahu i kēlā me kēia lā: No nā huahana ʻili no ka ʻaʻahu o kēlā me kēia lā, e like me nā kāmaʻa a me nā ʻeke lima, hiki i nā mea kūʻai ke koho e like me kā lākou makemake a me kā lākou kālā. Inā ʻoe e ʻimi i ka hōʻoluʻolu a me ka hanu, ʻoi aku ka maikaʻi o ka ʻili maoli; inā ʻoe e noʻonoʻo nui i ke kumukūʻai a me nā ʻano like ʻole, he koho maikaʻi nō hoʻi ka ʻili PU.

Nā hanana kūikawā: Ma kekahi mau hanana kūikawā, e like me nā hālāwaiʻoihana, nāʻaina ahiahi, a me nā mea'ē aʻe, nā huahanaʻili maoli e hōʻike pinepine i ka nani a me keʻano hanohano. I kekahi mau manawa maʻamau, e like me nā haʻuki waho, huakaʻi, a me nā mea ʻē aʻe, makemake ʻia nā huahana ʻili PU ma muli o ko lākou māmā a me ka lōʻihi.
I ka hōʻuluʻulu ʻana, loaʻa i ka ʻili PU a me ka ʻili maoli ko lākou mau hiʻohiʻona ponoʻī a me nā hiʻohiʻona kūpono. Pono nā mea kūʻai aku e koho e pili ana i kā lākou makemake a me kā lākou kālā ke kūʻai.
