He aha ka Polyurethane?He aha kāna mau hana a me kona ʻano?

I kēia mau lā, ʻoi aku ka nui o ka polyurethane ma ka mākeke.ʻO ka polyurethane he mea maʻalahi loa, akā ʻaʻole maopopo ka poʻe he aha ka polyurethane a i kāna hana.I ka pane ʻana i kēia kūlana, ua hōʻuluʻulu ka mea hoʻoponopono i kēia ʻike e hāʻawi iā ʻoe i ka ʻepekema kaulana.“

He aha ka Polyurethane?

ʻO ka inoa piha o ka polyurethane he polyurethane, he huaʻōlelo maʻamau no nā pūhui macromolecular i loaʻa nā hui urethane hou ma ke kaulahao nui.ʻO ka Polyurethane kahi pūʻulu liʻiliʻi o ka urethane ma koʻu ʻāina, a hiki nō ke komo i loko o ka ether ester urea biuret urea group first polyurethane introduction group.Hoʻokumu ʻia ia e ka polyaddition o ka diisocyanate organik a i ʻole polyisocyanate a me ka dihydroxyl a i ʻole polyhydroxyl compound.He nui ka hoʻohana ʻana o ka polyurethane, hiki iā ia ke hoʻololi i ka rubber, plastic, nylon, etc., i hoʻohana ʻia i nā mokulele, nā hōkele, nā mea kūkulu hale, nā hale hana kaʻa, nā mines lanahu, nā hale hana sima, nā hale kiʻekiʻe kiʻekiʻe, nā villas, landscaping, pōhaku kala. kiʻi, paka etc.

ʻO ka hana o ka polyurethane:

Hiki ke hoʻohanaʻia ka Polyurethane i ka hanaʻana i nā plastics, rubber, fibers, rigid and flexible foams, adhesives and coatings, etc.

1. Polyurethane foam: hoʻokaʻawale ʻia i loko o ka pahu polyurethane paʻa, ka pahu polyurethane semi-rigid a me ka pahu polyurethane maʻalahi.Hoʻohana nui ʻia ka polyurethane foam no ke kūkulu ʻana i nā mea hoʻoheheʻe wela, nā mea hoʻonaninani wela (ka insulation thermal o nā hale pipeline, etc.), nā mea e pono ai i kēlā me kēia lā (moe, sofas, etc. pads, refrigerators, air conditioners, etc., insulation layers, and surfboards. , a me nā mea nui. ), a me nā mea e lawe ai (nā mea e like me nā cushions a me nā kaupaku no nā kaʻa, mokulele, a me nā kaʻa kaʻaahi).

2. Polyurethane elastomer: Loaʻa i ka polyurethane elastomer nā mea maikaʻi o ka ikaika tensile maikaʻi, ka ikaika o ka waimaka, ka hopena o ka hopena, ke kū'ē abrasion, ke kū'ē i ka wā, ka pale hydrolysis, kaʻaila a me nā mea'ē aʻe.Hoʻohana nui ʻia no ka uhi ʻana i nā mea (e like me ka pale ʻana i nā hoses, nā mea holoi, nā kaila, nā wili, nā mea hana, nā paipu, a me nā mea ʻē aʻe), nā insulators, nā wāwae kāmaʻa, a me nā kaila paʻa.

3. ʻO nā mea wai wai polyurethane: He mea maʻalahi loa ka hoʻohanaʻana i ka polyurethane wai.Hiki ke hoʻohuiʻia a hoʻopiliʻia ma ka pūnaewele a ho'ōlaʻia me ka mahana maʻamau a me ka haʻahaʻa, a hiki ke loaʻa kahi papa wai me kaʻole o nā humu, ka elasticity rubber a me ka hana maikaʻi.A maʻalahi e hoʻoponopono ma hope o ka pōʻino.Hoʻohana maʻamau e like me nā mea paving, track and field track tracks, racetracks, park ground materials, thermal insulation window frames, etc.

4. ʻO ka uhi ʻana o ka polyurethane: ʻO ka uhi ʻana o ka polyurethane i hoʻopili ikaika ʻia, a ʻo ke kiʻi ʻoniʻoni ʻoi aku ka maikaʻi o ka pale ʻana i ka ʻaʻahu, ke kūpaʻa wai a me ka pale kemika.Hoʻohana nui ʻia no ka uhi ʻana i nā lako, nā mea kūkulu hale a me nā inika paʻi ʻoihana.

5. Polyurethane adhesive: Hiki ke hoʻololi i ka hana o ka huahana i ho'ōlaʻia ma ka hoʻololiʻana i ka ratio o ka isocyanate a me ka polyol, i hiki ai ke hoʻokō i ka hoʻopili kiʻekiʻe i ka substrate, ke kū'ēʻana i ka wai maikaʻi, ke kū'ēʻana i kaʻaila a me ka pale kemika.Hoʻohana nui ʻia nā polyurethane adhesives i ka ʻeke, kūkulu, lāʻau, kaʻa, hana kāmaʻa a me nā ʻoihana ʻē aʻe.

6. Nā mea biomedical: ʻO ka polyurethane ka biocompatibility maikaʻi loa, no laila ua hoʻohana nui ʻia e like me nā mea biomedical.Hiki ke hoʻohana ʻia i ka hana ʻana i nā pacemakers cardiac artificial, nā kīʻaha koko artificial, nā iwi artificial, esophagus artificial, nā puʻupaʻa artificial, nā membranes dialysis artificial, etc.

ʻO ka mea i luna nei kekahi mau ʻike pili e pili ana i ka mea polyurethane a me ke kuleana o ka polyurethane a ka mea hoʻoponopono i hōʻuluʻulu ai no ʻoe.Loaʻa iki ka Polyurethane i kahi paʻa paʻa i ka mākeke mea hale ma muli o kona kūpaʻa ʻana a me nā ʻano ʻē aʻe.Hiki i nā Netizens ke kūʻai e like me ko lākou pono ponoʻī home.

Hōʻike: Ua ʻōlelo ʻia ka ʻatikala mai https://mp.weixin.qq.com/s/c2Jtpr5fwfXHXJTUvOpxCg(loulou i hoʻopili ʻia).No ka kamaʻilio a me ke aʻo ʻana, mai hana i nā kumu pāʻoihana ʻē aʻe, ʻaʻole ia e hōʻike i nā manaʻo a me nā manaʻo o ka hui, inā pono ʻoe e paʻi hou, e ʻoluʻolu e kelepona i ka mea kākau kumu, inā he hewa, e ʻoluʻolu e kelepona koke iā mākou e hana i ka hana holoi.
