He aha ka ʻili PU?

Kapa ʻia ka ʻili PU i ka ʻili polyurethane, ʻo ia ka ʻili synthetic i hana ʻia me nā mea polyurethane. ʻO ka ʻili Pu he ʻili maʻamau, hoʻohana nui ʻia i nā ʻano huahana ʻoihana, e like me nā lole, nā kāmaʻa, nā lako, nā kaʻa kaʻa a me nā mea pono, ka pahu a me nā ʻoihana ʻē aʻe.

No laila, noho ka ʻili pu i kahi kūlana koʻikoʻi ma ka mākeke ʻili.

Mai ke kaʻina hana a me ka manaʻo palekana kaiapuni, ua māhele nui ʻia ka ʻili pu i ʻelua ʻano o ka ʻili pu hou a me ka ʻili pu kahiko.

He aha ka ʻokoʻa ma waena o nā ʻano ʻili ʻelua?

E nānā mua kākou i nā ʻokoʻa o kā lākou hana hana.

Kaʻina hana ʻili pu kuʻuna:

1. ʻO ka hana mua i ka hana ʻana i ka ʻili pu ka hana ʻana i ka polyurethane, a ʻo ka isocyanate (a i ʻole polyol) a me ka polyether, polyester a me nā mea maka ʻē aʻe i hana ʻia i polyurethane resin ma o ka hopena kemika.

2. Hoʻopili i ka substrate, polyurethane resin i uhi ʻia ma luna o ka substrate, e like me ka ʻili o ka ʻili pu, hiki ke koho ʻia ka substrate i nā ʻano textiles, e like me ka pulupulu, ka lole polyester, a me nā mea ʻē aʻe.

3. ʻO ka hana a me ka mālama ʻana, hoʻomaʻamaʻa ʻia ka substrate i uhi ʻia a mālama ʻia, e like me ka embossing, paʻi, dyeing a me nā kaʻina hana ʻē aʻe, i mea e loaʻa ai ke ʻano pono, ke kala a me ka hopena o ka ʻili. Hiki i kēia mau kaʻina hana ke hana i ka ʻili PU e like me ka ʻili maoli, a i ʻole he hopena hoʻolālā kikoʻī.

4. Ma hope o ka mālama ʻana: Ma hope o ka pau ʻana o ka hana ʻana, pono paha ka ʻili PU e hana i kekahi mau hana ma hope o ka mālama ʻana, e like me ka pale ʻana i ka uhi ʻana, ka mālama ʻana i ka wai, a me nā mea ʻē aʻe, e hoʻomaikaʻi i kona lōʻihi a me nā ʻano.

5. Ka mana maikaʻi a me ka ho'āʻoʻana: Ma nā pae a pau o ka hanaʻana, e hoʻokōʻia ka mana maikaʻi a me ka nānāʻana e hōʻoia i ka hoʻokōʻana o kaʻili PU i ka hoʻolālā a me nā koi kiko'ī.

ʻO ke kaʻina hana o ka ʻili pu hou:

1. E hōʻiliʻili a hana hou i nā huahana polyurethane ʻōpala, e like me nā huahana ʻili pu kahiko, nā ʻōpala hana, ma hope o ka hoʻokaʻawale ʻana a me ka hoʻomaʻemaʻe ʻana i ka lepo a me ka lepo, a laila e hana i ka mālama ʻana i ka maloʻo;

2. E pulumi i ka mea polyurethane maʻemaʻe i loko o nā ʻāpana liʻiliʻi a i ʻole ka pauka;

3. E hoʻohana i kahi huila e hui pū i nā ʻāpana polyurethane a i ʻole nā ​​pauka me nā polyurethane prepolymers, fillers, plasticizers, antioxidants, etc., a laila e hoʻokomo iā lākou i loko o nā mea hoʻomehana no ka hopena kemika e hana i kahi matrix polyurethane hou. Hana ʻia ka matrix polyurethane i kiʻiʻoniʻoni a i ʻole ke ʻano kikoʻī ma ka hoʻolei ʻana, ka uhi ʻana a i ʻole ka calendering.

4. Hoʻomaʻamaʻa ʻia ka mea i hana ʻia, hoʻomaʻamaʻa a hoʻōla ʻia e hōʻoia i nā waiwai kino a me ke kūpaʻa kemika.

5. Ua ho'ōla 'ia ka 'ili pu i ho'opō'ino 'ia, i ho'opili 'ia, i uhi 'ia, i ho'olu'u 'ia a me nā lā'au lapa'au 'ē a'e no ka loa'a 'ana o ka hi'ohi'ona i makemake 'ia;

6. E hana i ka nānā ʻana i ka maikaʻi e hoʻokō i nā kūlana kūpono a me nā koi. A laila e like me nā koi o ka mea kūʻai aku, ʻokiʻoki i nā ʻano nui a me nā ʻano o ka ʻili i hoʻopau ʻia;

Ma o ke kaʻina hana, hiki ke hoʻomaopopo ʻia i ka hoʻohālikelike ʻia me ka ʻili pu kuʻuna, ʻoi aku ka nānā ʻana o ka ʻili pu i hana hou ʻia i ka mālama ʻana i ke kaiapuni a me ka hana hou ʻana i nā kumuwaiwai, e hōʻemi ana i ka pollution kaiapuni. Loaʻa iā mākou nā palapala hōʻoia GRS no ka ʻili pu a me ka pvc, e mālama ana i ka manaʻo o ka hoʻomohala hoʻomau a me ka mālama ʻana i ke kaiapuni, a me ka hana i ka hana ʻili.
