Pounamu kua whakakiia ki te wera PET Resin
Whakataki Hua
Ko nga maramara polyester kua oti te whakakii wera kua oti te hanga me te whakaputa motuhake mo nga ipu whakakī wera e ai ki nga inu tii, inu hua-wai me etahi atu momo momo inu me whakamahana mo te whakahoromata.
Ko te tohu o te hua e whakaatu ana i te iti o te ihirangi konganuku taumaha, te iti o te ihirangi o te acetaldehyde, te uara tae pai, te pokey pumau me te pai mo te tukatuka.Ki te tunu tukanga ahurei me te hangarau hanga matatau, te hua, ka te thermoformed i roto i te SIPA、SIDEL、ASB me ētahi atu mihini pounamu-hanga tuatahi i raro i ngā tikanga whānui, he tere tropism teitei, crystallinity pūmau me te wai pai ki te reiti ahotea-tuku iti i roto i. Ko te katoa o te pounamu, te tere o te whakahekenga waiariki me te reiti hua kua oti i roto i te hanga ipu, ka taea te whakatutuki i te hiahia o te pounamu ki te 90°C me te whakamarumaru i nga inu mai i te rerekee, i te waiora ranei i roto i te waa rokiroki me te aukati i te huringa o nga ipu.
