Waa maxay polyurethane
Polyurethane (PU), magac buuxa polyurethane, waa shey polymethane ah oo leh astaamo farsamo oo aad u wanaagsan oo ay sameysay polyolol iyo falcelinta polyisote ah iyada oo loo marayo falcelin polyconsis ah, oo aad u caag ah. Isku-darka 'Synthesis' waxaa lagu raad joojin karaa 1937, marka Prof. Prof. Sings Shints silsiladaha tooska ah ee Tooska Tooska ah iyadoo la adeegsanayo 1,6-hexananedisocyate iyo 1,4-basancediol sida abbaaw cayriin ah. Dhowr nooc oo waaweyn oo polyuretranes waxaa ka mid ah nooca polyretherther-nooca, nooca polyeride-nooca, nooca polylureane---maadada polyurethane (oo loo yaqaan 'polyurethane' (oo loo yaqaan Spandex ee Shiinaha), polyurethane rug, iyo taraamyo.
Ka dib ku dhawaad siddeetan sano oo horumarineed ah, agabyada polyurethane waxay leeyihiin codsiyo fara badan oo fara badan oo ku lug leh badeecadaha sida jaakadaha, maqaarka maqaarka, maqaarka jilicsan ee maqaarka / adag, kuwaas oo loo adeegsado beeraha dharka , Dhismaha, Duulista, Dhismaha, Gaadiidka, Daawada iyo Elektiroonigga. Polyaurethane dabacsan ayaa badanaa leh qaab dhismeedka toosan, kaas oo leh xasillooni wanaagsan, caabbinta kiimikada, adkeysiga kiimikada ee ka badan noocyada pvc ee pvc. Dambiilaha kuleylka, xijaabka codka, iska caabbinta naxdinta leh, waxqabadka ka hortagga fayraska ayaa wanaagsan. Sidaa darteed, waxaa loo isticmaalaa sidii baakado, dahab dhawaq iyo waxyaabo shaandhaynaya. Caagga adag ee poranurethane waa khafiifa, xishoodka dhawaaqa, waxqabadka kuleylka kuleylka ee ka sarreeya, iska caabbinta kiimikada, guryaha korantada wanaagsan, ka baaraandeg fudud, nuugista biyaha. Waxaa inta badan loo isticmaalaa dhismaha, gawaarida, warshadaha duulista, Qalabka Qaab-dhismeedka kuleylka kuleylka. Waxqabadka polyurethane emastom ee u dhexeeya caagga iyo caagga, iska caabbinta saliida, iska caabbinta dibada, iska caabinta heerkulka, caabbinta da 'yarta ah, adkeynta sare, adkaata, adkaata. Waxaa inta badan loo isticmaalaa warshadaha kabaha iyo warshadaha caafimaad. Polyurethane sidoo kale wuxuu ka dhigi karaa caqabado, jaakad, maqaar isku-dhafan, iwm.
