ʻO ka polystyrene i hoʻonui ʻia (EPS), ka polystyrene extruded (XPS) a me ka polyurethane (PU) i kēia manawa ʻekolu mau mea kūlohelohe i hoʻohana nui ʻia i ka pale ʻana o ka paia o waho.Ma waena o lākou, ʻike ʻia ʻo PU ʻo ia ka mea insulation maikaʻi loa i ka honua, nona ka conductivity thermal haʻahaʻa ma waena o nā mea insulation āpau.I ka 35 ~ 40 kg/m3 ka mānoanoa o ka paakiki PU, kona thermal conductivity wale 0.018 ~ 0.023W/(mK).ʻO ka hopena insulation o 25mm-mānoanoa ʻoʻoleʻa PU huʻihuʻi e like me ka 40mm-mānoanoa EPS, 45mm-mānoanoa mineral hulu hipa, 380mm-mānoanoa ka pōhaku lepo maʻamau a 860mm-mānoanoa.No ka loaʻa ʻana o ka hopena insulation like, ʻo kona mānoanoa ma kahi o ka hapalua o ka EPS.

ʻO kahi hōʻike hou i hōʻike ʻia ʻo kekahi o nā kumu o ka hoʻolaha wikiwiki ʻana o ke ahi ma Hangzhou Ice and Snow World ʻo ia ka PU insulation material a simulated plastic green plants i hoʻohana ʻia i loko o nā hale ʻaʻole i hoʻokō i nā koi o ka non-combustibility a me ke ahi retardancy. a poha koke ka uahi mahope o ke ahi.ʻO ke kumu ʻelua, ʻo ia ka hoʻokaʻawale ʻana i ke ahi a me ka pale ʻana i ka uahi ma waena o Hangzhou Ice a me Snow World a me nā wahi ʻē aʻe o ka hale.Hana ʻia ka pā o loko me ka panel sandwich PU, a ʻo nā puka puka he mau puka insulated thermal ma mua o nā puka i hoʻopaʻa ʻia i ke ahi, ka mea i hoʻolaha koke ʻia ke ahi i ka papahele ʻelua ma hope o ke ahi ʻana.

ʻO kekahi kumu o ka poʻe i make, ʻo ia ma hope o ke ahi ʻana, ua ʻā nā mea e like me ka PU a me nā mea kanu plastik ma kahi ākea, e hoʻopuka ana i ka nui o ka uahi ʻawaʻawa kiʻekiʻe, a ʻo ka uahi ahi i hoʻokuʻu ʻia e hōʻuluʻulu mau a hoʻopau i ka deflagration. ka hopena o ka poino.

ʻO ka mea hikiwawe loa, ua lilo nā mea hoʻoheheʻe PU i mea hoʻohewa a hāʻule i loko o kahi ʻino o ka manaʻo o ka lehulehu!

Ma ka noʻonoʻo ʻana i kēia pauku, he ʻaoʻao hoʻokahi ka ʻōlelo, a ʻelua mau hemahema.

ʻO ka mea mua: ʻAʻole kūpono nā mea hoʻonaninani PU a me nā mea kanu ʻōmaʻomaʻo i hoʻohana ʻia i loko o nā hale i nā koi o ka non-combustibility a me ke ahi retardancy.

Wahi a ka GB8624-1997 Classification for Burning Behavior of Building Products, B2-level polyurethane hiki ke hoʻonui ʻia i ka pae B1 ma hope o ka hoʻohui ʻana i nā mea pale ahi kūikawā.ʻOiai ua loaʻa i nā papa insulation PU nā hiʻohiʻona o nā mea kūlohelohe, hiki iā lākou ke hōʻea i ka pae ahi ahi o B1 ma lalo o nā kūlana ʻenehana o kēia manawa.Eia kekahi, aia nō nā bottlenecks ʻenehana a me nā pilikia i ka hoʻomohala ʻana a me ka hana ʻana i nā papa insulation PU pae B1.Hiki i nā papa PU i hana ʻia e ka hapa nui o nā ʻoihana liʻiliʻi a me ka nui o Kina ke hiki i ka pae B2 a i ʻole B3.Eia nō naʻe, hiki i nā mea hana nui ma Kina ke hoʻokō.Hana ʻia nā papa insulation PU mai ka polyether hui ʻia a me ka PMDI (Polymethylene polyphenyl polyisocyanate) no ka hoʻoulu ʻana i ka huʻi a hoʻopaʻa ʻia ʻo B1 flame-retardant e ka GB8624-2012 maʻamau.Hoʻohana nui ʻia kēia mea insulation organik i nā kahua o nā hale hoʻōla hoʻōla i ka ikehu, ka mālama anuanu nui a me ke kaulahao kaulahao.Hiki ke hoʻohana ʻia no ka pale ʻana i ke ahi a me ka insulation thermal i nā mea kanu ʻoihana, nā moku, nā kaʻa, ka hana mālama wai a me nā ʻāpana ʻē aʻe he nui.

ʻO ka lua: Ua palahalaha koke ka uahi ma hope o ke ahi a me ka mea hoʻoheheʻe PU he mea make.

Nui ka hoʻopaʻapaʻa e pili ana i ka ʻona o ka polyurethane, ʻoi aku ka nui o nā ulia e like me ka puhi ʻana o nā mea PU.I kēia manawa, ʻike nui ʻia ka polyurethane i hoʻōla ʻia ma ke ʻano he mea ʻawaʻawa ʻole, a ua hoʻohana ʻia kekahi mau mea lapaʻau PU i nā mea lapaʻau implantable a me nā ʻāpana.Akā ʻo ka polyurethane i hoʻomaʻemaʻe ʻole ʻia hiki ke lilo i mea ʻawaʻawa.ʻO ka puʻupuʻu PU koʻikoʻi he ʻano mea thermosetting.Ke puhi ʻia, hoʻokumu ʻia kahi papa kalapona ma luna o kona ʻili, a hiki i ka papa carbonized ke pale i ka laha ʻana o ka lapalapa.ʻO EPS a me XPS nā mea wela wela e hoʻoheheʻe a kulu i ka wā e ʻike ʻia ai i ke ahi, a hiki i kēia mau kulu ke ʻā.

ʻAʻole i hoʻokumu ʻia ke ahi ma muli o nā mea insulation wale nō.Pono e noʻonoʻo ʻia nā hale ma ke ʻano he ʻōnaehana.ʻO ka hana ahi o kahi ʻōnaehana holoʻokoʻa e pili ana i nā mea like ʻole e like me ka hoʻokele kūkulu hale a me ka mālama ʻana i kēlā me kēia lā.He mea liʻiliʻi ka hoʻokūpaʻa makapō i ka pae ʻana o ka lapalapa ahi o nā mea kūkulu hale."ʻOiaʻiʻo, maikaʻi ka waiwai ponoʻī.ʻO ke kī ʻo ia ka hoʻohana pono a me ka maikaʻi.E like me nā makahiki i hala aku nei, ua hoʻoikaika pinepine ʻo Li Jianbo, ka hope kākau ʻōlelo nui o China Polyurethane Industry Association, i nā pilikia like ʻole i nā ʻaha kūkā a me nā seminar.ʻO ka hoʻokele ʻino ʻana o ke kahua kūkulu hale a me ka mākaʻikaʻi maikaʻi ʻole o nā huahana kūpono ʻole a kūpono ʻole ke kumu nui o ke ahi, a ʻaʻole pono mākou e kuhikuhi i ka manamana lima i nā mea ke loaʻa kahi pilikia.No laila, i kēia manawa, mau ka pilikia.Ua ʻike makapō ʻia ʻo ia ka pilikia o nā mea PU, ʻo ka hopena paha he ʻaoʻao hoʻokahi.
