ʻO ka polyurethane i ka hapa nui o nā mea hoʻohua

ʻO ka polyurethane (PU) foam ka huahana e hōʻike ana i ka hapa nui o nā mea hoʻohāhā ma Kina.

ʻO ka mea nui o ka polyurethane foam he polyurethane, a ʻo ka mea maka he isocyanate a me polyol. Ma ka hoʻohui ʻana i nā mea hoʻohui kūpono, hana ia i ka nui o ka pua i hana ʻia i loko o ka huahana hopena, i loaʻa ai nā huahana polyurethane foam.

Hoʻokaʻawale nui ʻia ka polyurethane foam i loko o ka flexible foam, rigid foam a me spray foam. Hoʻohana ʻia nā ʻūhā maʻalahi i nā ʻano like ʻole e like me ka cushioning, ka lole ʻaʻahu a me ka kānana, ʻoiai ʻo nā ʻūhā paʻa e hoʻohana nui ʻia no nā panela insulation thermal a me ka insulation laminated i nā hale kūʻai a me nā hale noho a me (spray) foam roofing.

ʻO ka polyurethane foam ʻoʻoleʻa ka hapa nui o ka hale paʻa-cell a loaʻa nā waiwai maikaʻi e like me ka insulation thermal maikaʻi, ke kaumaha māmā a me ke kūkulu maʻalahi.

Loaʻa iā ia nā hiʻohiʻona o ka insulation leo, shockproof, insulation uila, heat resistance, cold resistance, solvent resistance, etc.

Hiki ke hoʻohana ʻia ka pahu polyurethane paʻa i ka uhi ʻana o ka hale a me ka paia, ka puka a me ka puka makani a me ka hoʻopaʻa ʻana i ka pale pale. Eia nō naʻe, e hoʻomau ka hoʻokūkū polyurethane foam i ka hoʻokūkū mai fiberglass a me PS foam.

ʻO ka pahu polyurethane maʻalahi

Ua ʻoi aku ka nui o ka noi no ka ʻūhā polyurethane maʻalahi ma mua o ka ʻōhū polyurethane paʻa i nā makahiki i hala. ʻO ka pahu polyurethane maʻalahi kahi ʻano o ka polyurethane foam maʻalahi me kahi pae o ka elasticity, a ʻo ia ka huahana polyurethane i hoʻohana nui ʻia.

ʻO ka nui o nā huahana i loaʻa i ka huʻa kiʻekiʻe resilient (HRF), block sponge, slow resilient foam, self-crusting foam (ISF), a me semi-rigid energy-absorbing foam.

ʻO ke ʻano ʻōhū o ka polyurethane flexible foam ka hapa nui o ka pore. ʻO ka mea maʻamau, he haʻahaʻa haʻahaʻa, hoʻoheheʻe leo, breathability, mālama wela a me nā waiwai ʻē aʻe, i hoʻohana nui ʻia e like me nā mea cushioning lako, nā mea hoʻokele noho kaʻa, nā mea hoʻonaninani laminated composite. ʻO ka hoʻohana ʻana i ka ʻoihana a me ke kīwila o ka huʻu palupalu e like me nā mea kānana, nā mea hoʻoheheʻe kani, nā mea haʻalulu, nā mea hoʻonaninani, nā mea hoʻopili a me nā mea hoʻoheheʻe wela.

Polyurethane hoʻonui hoʻonui manawa

Ke ulu wikiwiki nei ka ʻoihana polyurethane foam o Kina, ʻoi aku ka nui o ka ulu ʻana o ka mākeke.

Hiki ke hoʻohana ʻia ka polyurethane foam ma ke ʻano he puʻupuʻu paʻa a i ʻole ka padding buffer material no nā mea hana kiʻekiʻe kiʻekiʻe, nā mea hana waiwai, nā mea hana lima kiʻekiʻe, a me nā mea ʻē aʻe. hiki ke hoʻohana ʻia no ka hoʻopaʻa ʻana i nā mea ma ka hoʻoulu ʻana ma ka pūnaewele.

Hoʻohana nui ʻia ka polyurethane rigid foam i loko o ka adiabatic insulation, refrigeration a me nā mea hoʻoheheʻe a me ka mālama anu, nā panela adiabatic, ka pale ʻana i ka paia, ka paipu ʻana, ka insulation o nā pahu mālama, nā mea hoʻoheheʻe hoʻokahi-hui, etc.; Hoʻohana nui ʻia ka polyurethane soft foam i nā lako, nā moena a me nā huahana ʻē aʻe o ka hale, e like me nā sofas a me nā noho, nā cushions hope, nā moena a me nā uluna.

Loaʻa nā noi i loko o: (1) nā pahu hau, nā ipu, ka insulation freezers (2) PU simulation pua (3) paʻi pepa (4) cable chemical fiber (5) kiʻekiʻe kiʻekiʻe ala (hōʻailona pale pale) (6) hale hoʻonani (foam board decor) (7) lako (seat cushion, moena sponge, backrest, armrest, etc.) (8) foam filler (8) cushion, kaʻa poʻo, hoʻokele huila (10) kiʻekiʻe kiʻekiʻe haʻuki waiwai lako (mea pale, lima kiaʻi, kapuaʻi kiaʻi, boxing mīkina lima lining, mahiole, etc.) (11) synthetic PU ili (12) hana kamaa (PU kapuaʻi) (13) maʻamau (14) kūikawā pale pale (15).

ʻO ke kikowaena o ka umekaumaha o ka hoʻomohala ʻana i ka polyurethane foam ma ka honua holoʻokoʻa ua neʻe mālie i Kina, a ua lilo ka polyurethane foam i kekahi o nā ʻoihana ulu wikiwiki loa i ka ʻoihana kemika o Kina.

I nā makahiki i hala iho nei, ʻo ka hoʻomohala wikiwiki ʻana o ka insulation refrigeration home, ke kūkulu ʻana i ka ikehu, ka ʻoihana ikehu lā, nā kaʻa, nā lako a me nā ʻoihana ʻē aʻe i hoʻonui nui i ka noi no ka polyurethane foam.

I loko o ka manawa "13th Five-Year Plan", ma kahi kokoke i 20 mau makahiki o ka ʻai ʻana, absorption a me ka hana hou ʻana o ka ʻoihana polyurethane raw material, MDI production technology a me ka mana hana i waena o nā pae kiʻekiʻe o ka honua, polyether polyol production technology a me ka noiʻi ʻepekema a me ka hiki ke hoʻomau i ka hoʻomaikaʻi ʻana, hoʻomau nā huahana kiʻekiʻe e puka mai me nā pae kiʻekiʻe. 2019 Kina ʻO ka hoʻohana ʻana i nā huahana polyurethane ma kahi o 11.5 miliona tons (me nā solvents), ke hoʻonui nei ka lawe ʻana aku i nā mea maka i kēlā me kēia makahiki, a ʻo ia ka nui o ka honua polyurethane hana a me ka ʻai ʻāina, ʻoi aku ka nui o ka mākeke.

E like me ka pālākiō o ka 'oihana, o ka market nui o polyurethane 'ano foaming mea helu no ka hapa nui loa, me ka market nui o ma kahi o 4.67 miliona tons, o ka mea nui soft foam polyurethane foaming mea, helu no ma kahi o 56%. Me ka ulu nui ʻana o nā māla uila a me nā uila ma Kina, ʻoi aku ka hoʻonui ʻana o ka friji a me nā noi hale, ke hoʻomau nei ka ulu ʻana o ka mākeke o ka polyurethane foaming material.

I kēia manawa, ua piʻi ka ʻoihana polyurethane i kahi pae hou me ka hoʻomohala alakaʻi hou a me ka hoʻomohala ʻōmaʻomaʻo e like me ke kumuhana. I kēia manawa, ʻo ka hoʻopuka ʻana o nā huahana polyurethane downstream e like me nā mea kūkulu hale, spandex, ʻili synthetic a me nā kaʻa i Kina ke kūlana mua ma ka honua. Ke hoʻoikaika ikaika nei ka ʻāina i ka uhi ʻana i ka wai, hoʻokō i nā kulekele hou e pili ana i ke kūkulu ʻana i ka mālama ʻana i ka ikehu a me ka hoʻomohala ʻana i nā kaʻa ikehu hou, e lawe pū ana i nā manawa mākeke nui no ka ʻoihana polyurethane. ʻO ka pahuhopu "ʻelua carbon" i manaʻo ʻia e Kina e hoʻoikaika i ka hoʻomohala wikiwiki ʻana o ka kūkulu ʻana i ka ikehu a me ka ʻoihana ikehu maʻemaʻe, kahi e lawe mai ai i nā manawa hoʻomohala hou no nā mea insulation polyurethane, coatings, composite material, adhesives, elastomers, etc.

Ke koi nei ka mākeke kaulahao anuanu i ka noi no ka polyurethane rigid foam

Ua hoʻopuka ke Keʻena Nui o ka ʻAha Mokuʻāina i ka "Hoʻolālā ʻumikūmāhā mau makahiki ʻelima" hoʻolālā hoʻomohala logistic kaulahao i ka makahiki 2020, ʻo ka nui o ka mākeke logistic chain o Kina i ʻoi aku ma mua o 380 biliona yuan, ka nui o ka mālama anuanu o kahi kokoke i 180 miliona cubic mika, nona nā kaʻa i loko o ka friji ma kahi o 287,000, ʻo ia hoʻi, ʻo ka "-Twelt Plan of the end of the end of 5. 2.4 manawa, 2 manawa a me 2.6 manawa.

I loko o nā mea insulation he nui, ʻoi aku ka maikaʻi o ka hana insulation polyurethane, hoʻohana nui ʻia. Ke hoʻohālikelike ʻia me nā mea ʻē aʻe, hiki i nā mea insulation polyurethane ke mālama ma kahi o 20% o nā lilo uila o ka mālama anuanu nui, a ke hoʻonui mālie nei ka nui o ka mākeke me ka hoʻomohala ʻana o ka ʻoihana logistics kaulahao. ʻO ka manawa "14th Five-Year", ke hoʻomau nei nā kamaʻāina a me nā kamaʻāina i ka hoʻomaikaʻi ʻana i ka hoʻolālā ʻai, ʻo ka hiki o ka mākeke nui ke hoʻolalelale i ka hoʻokuʻu ʻana i nā logistic kaulahao e hana i kahi ākea.
