Ruwan Ruwa Mai Cike Kwalban PET
Gabatarwar Samfur
An ƙera chips ɗin polyester mai cike da zafi kuma an samar da shi musamman don kwalabe masu zafi bisa ga abin sha na shayi, abubuwan sha-ruwan 'ya'yan itace da sauran abubuwan sha masu matsakaici suna buƙatar zama a cikin kwalabe masu zafi don haifuwa.
Alamar samfurin tana da ƙarancin ƙarfe mai nauyi, ƙarancin abun ciki na acetaldehyde, ƙimar launi mai kyau, ɗanɗano mai ƙarfi kuma mai kyau don sarrafawa.Tare da na musamman tsari girke-girke da kuma ci-gaba samar da fasaha, da samfurin, lokacin da ake thermoformed a SIPA, SIDEL, ASB da dai sauransu primary kwalban-yin inji a karkashin general yanayi, yana da high tropism kudi, barga crystallinity da kyau fluidity tare da low danniya-saki kudi a dukan kwalabe, barga thermal contraction rate da high ƙãre samfurin kudi a yin kwalabe, iya biya da ake bukata da ake kwalabe a game da 90 ° C da kuma kare abin sha daga discoloration ko oxidization a lokacin ajiya da kuma hana nakasawa na kwalabe.
