"JADE" Brand homopolyester "CZ-333" kwalban sa polyester kwakwalwan kwamfuta siffofi low nauyi karfe abun ciki, low abun ciki na acetaldehyde, mai kyau launi darajar, Barga danko da kyau ga aiki. crystallinity da mai kyau fluidity tare da low danniya-saki kudi a cikin dukan kwalban, barga thermal kwangila kudi da kuma high ƙãre samfurin kudi a yin kwalabe, iya gamsar da bukatar da ake kwalabe a game da 90 ° C da kuma kare sha daga discoloration ko oxidization a lokacin ajiya da kuma hana nakasawa na kwalabe.
Aikace-aikace
Ana amfani da shi musamman don kwalabe masu zafi bisa ga waccan abubuwan sha na shayi, abubuwan sha masu ruwan 'ya'yan itace da sauran abubuwan sha masu matsakaici suna buƙatar a sanya kwalabe mai zafi don haifuwa.
Yanayin sarrafawa na yau da kullun
Bushewa ya zama dole kafin aikin narkewa don hana guduro daga hydrolysis. Yanayin bushewa na yau da kullun shine zafin iska na 165-185 ° C, lokacin zama na sa'o'i 4-6, zafin raɓa a ƙasa -40 ℃. Yawan zafin jiki na ganga kusan 285-298 ° C.
