Fesa Busassun Foda Mai Watsewa da Gudun Urea Formaldehyde
Redispersible polymer foda ne powdery thermoplastic guduro yi ta hanyar fesa bushewa da kuma m jiyya na high kwayoyin polymer emulsions. Yawanci farin foda ne, amma kaɗan na ɗauke da wasu launuka. Ana amfani da shi sosai wajen gini, musamman wajen haɓaka haɗin kai, haɗin kai, da sassauƙar busassun turmi mai gauraya.
Samar da redispersible roba foda ya kasu kashi biyu matakai: mataki na farko shi ne don samar da wani polymer emulsion ta hanyar emulsion polymerization, da kuma mataki na biyu shi ne don fesa-bushe cakuda shirya daga polymer emulsion don samun polymer foda.
Tsarin bushewa: Ana ɗaukar emulsion na polymer da aka shirya zuwa na'urar bushewa ta bututun dunƙule don bushewa. Matsakaicin zafin jiki a mashigar na'urar bushewa shine gabaɗaya 100 ~ 200ºC, kuma madaidaicin shine gabaɗaya 60 ~ 80 ºC. Saboda bushewar feshi yana faruwa a cikin 'yan daƙiƙa kaɗan, rarraba barbashi yana "daskararre" a wannan lokacin, kuma colloid mai kariya yana aiki azaman barbashi na sarari don ware shi, ta haka yana hana haɗuwar ƙwayoyin polymer da ba za a iya jurewa ba. Don hana foda na roba daga "caking" a lokacin sufuri da ajiya, ana buƙatar ƙara wani wakili mai hana yin burodi a lokacin bushewa ko bayan bushewa.
