Hoʻohana ʻia ʻo Polyurethane

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

1. Puka Polyurethane:

Hoʻokaʻawale ʻia i loko o ka ʻōpū polyurethane ʻoʻoleʻa, ka ʻūhā polyurethane semi-rigid a me ka pahu polyurethane maʻalahi.Hoʻohana nui ʻia ka polyurethane foam no ke kūkulu ʻana i nā mea hoʻonaninani wela, nā mea hoʻonaninani wela (nā hale paipu, etc., insulation thermal a me ka hoʻohana ʻana i kēlā me kēia lā) (moe, sofas, etc., mattresses, refrigerators, air conditioners, etc., insulation layers, and etc. nā papa heʻe nalu, a me nā mea nui, a me ka lawe ʻana (nā kaʻa, nā mokulele, nā kaʻa kaʻaahi, nā cushions, nā kaupaku a me nā mea ʻē aʻe).

2. Polyurethane elastomer:

Loaʻa i ka polyurethane elastomer nā mea maikaʻi o ka ikaika tensile maikaʻi, ka ikaika o ka waimaka, ka pale ʻana i ka hopena, ka pale ʻana i ka abrasion, ka pale ʻana i ka wā, ke kūpaʻa hydrolysis, ka pale ʻana i ka aila a pēlā aku.Hoʻohana nui ʻia no ka uhi ʻana i nā mea (e like me ka pale ʻana i nā hoses, nā mea holoi, nā kaʻa, nā wili, nā mea hana, nā paipu, a me nā mea ʻē aʻe), nā insulators, nā kāmaʻa, a me nā kaila paʻa.

3. Polyurethane mea wai ole:

He mea maʻalahi loa ka hoʻohana ʻana i nā mea wai polyurethane.Hiki ke hoʻohuiʻia ma ka pūnaewele a ho'ōlaʻia me ka mahana maʻamau a me ka haʻahaʻa ma hope o ka uhiʻana, a laila hiki ke loaʻa kahi papa waiʻole me ka hiliʻole, 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. Ka uhi polyurethane:

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

5. Hoʻopili polyurethane:

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, ka maikaʻi o ka wai kūpaʻa, kaʻaila kū'ē 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. Mea olaola:

He biocompatibility maikaʻi loa ka Polyurethane, 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.
