PU resin & uhi

wehewehe pōkole:

Loaʻa nā resins hoʻoheheʻe polyurethane ma nā ʻano a me nā nui āpau.ʻO nā pōmaikaʻi o nā resins PU e like me nā ʻano i loaʻa.Hiki ke hoʻohana ʻia nā resins polyurethane no nā ʻano like ʻole a me nā ʻano hoʻohālike.Eia kekahi, hiki ke hoʻohana ʻia ma lalo o nā ʻenehana vacuum a ma ka ʻoihana composite.ʻIke ʻia nā resins polyurethane no ko lākou elasticity kiʻekiʻe a me ke kūpaʻa ʻaʻahu maikaʻi a me ke kūʻē kemika.

He aha ka polyurethane?

ʻO ka Polyurethane kahi plastic i hoʻopau ʻia ʻo PUR.No nā polymers kēia plastic a he ʻelua mau ʻāpana like ʻole: kahi ʻāpana paʻakikī a me kahi ʻāpana palupalu.No ka mea, aia ka PU i nā ʻāpana paʻakikī a palupalu hoʻi, he rubbery ka mea.Ma waho aʻe o nā ʻāpana ʻelua, hiki ke hoʻokaʻawale ʻia ʻo PUR i kahi resin (coating) a me kahi pahu.

Aia ka plastic i nā mana 1- a me 2-component.Aia nā ʻāpana ʻelua i ka ʻāpana A, ka resin kumu, a me ka ʻāpana B, ka mea paʻakikī.Me nā resins polyurethane hoʻohana ʻoe i kahi paʻakikī kūikawā no kekahi wahi o ka noi.Ma hope o ka hoʻohui ʻana i kēia mea paʻakikī wai i ka ʻāpana A, hiki ke kaʻina hana kemika.Mālama kēia hana i ka paʻakikī o ka resin.Ma muli o ke ʻano o ka hardener, e hoʻololi kēia i ka wikiwiki a me nā waiwai waiwai.Me nā PU he mea nui e mālama i nā ʻāpana kūpono.Ma muli o ke ʻano o ka ʻāpana, e paʻa mau ana kāu mea waiwai a i ʻole elastic elastic ma hope o ka hoʻōla ʻana.Me ka mana o ka foam, hoʻonui ka mea i ka leo e like me kona nui.

He kiʻi kokoke loa o kahi mea hana hana e ninini ana i ka resin epoxy mai ka bākeke ma luna o ka papahele

ʻO ka hoʻohana ʻana i ka polyurethane

Hiki ke hoʻohana ʻia nā resins polyurethane e like me nā uhi, primers, adhesives, lacquers, pena a i ʻole ka hoʻolei ʻana i nā resins.E like me ka pena polyurethane māmā a me ka pale UV no ka metala a i ʻole ka lāʻau.He kūpono no ka hoʻopau ʻana i ka parquet a i ʻole ka papahele hoʻolei.Eia kekahi, hoʻohana pū ʻia ka mea e like me ka ʻili artificial a hoʻohana ʻia i nā kāmaʻa wāwae.

ʻAʻole palena ʻole ka hoʻohana ʻana i nā resins polyurethane a hoʻolaha i nā ʻāpana like ʻole.

Papa hoolele PU

Ua kaulana nā papahele polyurethane i ka mākeke kūloko i nā makahiki i hala iho nei ma ke ʻano he hoʻopau no nā lumi noho, nā lumi kuke a me nā lumi moe.Mahalo i kāna mau waiwai hoʻonaʻauao ponoʻī, hana kēia resin i kahi hoʻopau papahele maikaʻi loa a hou.Loaʻa i nā kala like ʻole e kūlike me ka leo o kou loko.Mahalo i kāna mau waiwai elastic, hiki iā ʻoe ke hoʻohana iā ia me ka hoʻomehana ʻana ma lalo o ka papahele a loaʻa i kahi hopena paʻa loa a paʻa.

PUR pena Sealine

ʻO kekahi o nā noi maʻamau o PU e like me ka varnish a i ʻole ka uhi.Mahalo i ke kūpaʻa UV maikaʻi loa, ua hoʻohana ʻia kahi pena 2K polyurethane i nā noi ʻoihana no nā makahiki.ʻOi loa ma ka ʻoihana halihali, ka moana a me ke kūkulu hale.ʻO ka lōʻihi a me ke aniani kiʻekiʻe e hana ʻo Sealine PUR i mea hoʻopau kūpono no ka pena ʻana i kāu moku.
