Giraanta shaabadaynta Polyurethane waxaa lagu gartaa iska caabbinta xirashada, saliidda, aashitada iyo alkali, ozone, gabowga, heerkulka hooseeya, jeexjeexa, saameynta, iwm. Giraanta shaabadaynta Polyurethane waxay leedahay awood taageero culeys oo weyn waxaana si weyn loogu isticmaalaa meelo kala duwan. Intaa waxaa dheer, giraanta shaabadaynta ee la shubay waa mid u adkaysata saliidda, u adkaysata hydrolysis, u adkaysata xirashada, waxayna leedahay xoog sare, taas oo ku habboon qalabka saliidda cadaadiska sare leh, qalabka kor u qaadista, qalabka mashiinka sameynta, qalabka haydarooliga waaweyn, iwm.
Giraanta shaabadda Polyurethane: polyurethane waxay leedahay sifooyin farsamo oo aad u wanaagsan, iska caabinteeda xirashada iyo iska caabinta cadaadiska sarena aad ayay uga sarreeyaan caagagga kale. Iska caabbinta gabowga, iska caabbinta ozone-ka iyo iska caabbinta saliidda ayaa sidoo kale aad u fiican, laakiin way fududahay in la hawo-geliyo heerkulka sare. Guud ahaan waxaa loo isticmaalaa isku-xidhka shaabadda ee u adkeysan kara cadaadiska sare iyo kuwa u adkeysan kara xirashada, sida dhululubada haydarooliga. Guud ahaan, heerkulka waa - 45~90 ℃.
Marka laga soo tago buuxinta shuruudaha guud ee agabka shaabadaynta, faraantiga shaabadaynta polyurethane waa inay sidoo kale fiiro gaar ah u yeeshaan shuruudaha soo socda:
(1) Ka buuxa dabacsanaan iyo adkeysi;
(2) Awood farsamo oo ku habboon, oo ay ku jiraan xoogga ballaarinta, dheereynta iyo iska caabbinta jeexjeexa.
(3) Waxqabad deggan, oo ay adag tahay in lagu bararo dhexdhexaadka, iyo saameynta yar ee kulaylka yar (saamaynta Joule).
(4) Way fududahay in la farsameeyo oo la qaabeeyo, waxayna ilaalin kartaa cabbirka saxda ah.
(5) Ma mirqo dusha sare ee taabashada oo ma wasakheeyo qalabka.
Ningbo Yokey Automotive Parts Co., Ltd waxay diiradda saartaa xallinta dhibaatooyinka alaabta caagga ah ee macaamiisha iyo naqshadeynta qaacidooyin kala duwan oo agab ah oo ku salaysan xaalado codsi oo kala duwan.
