Kedu ihe kpatara ndị na-emepụta ihe egwuregwu ụmụaka ji ahọrọ ihe TPR?

TPR bụ ụdị polymer dị nro nwere njirimara modulation.Dị ka ihe dị iche iche chọrọ nke ndị ahịa, ndị na-ebubata ya na-enye usoro usoro ihe onwunwe TPE na TPR na ngwọta ngwa.Ike nke ikike R & D bụ ihe dị mkpa iji nyochaa ike zuru oke nke ndị na-emepụta TPE na TPR.

Kedu ihe kpatara ọtụtụ ndị na-emepụta ihe egwuregwu ụmụaka ji ahọrọ ihe TPE kama ihe PVC, nke mbụ bụ nchebe gburugburu ebe obibi.TPE na TPR enweghị phthalate plasticizer na halogen, na combustion nke TPE na TPR adịghị ahapụ dioxin na ndị ọzọ na-emerụ ihe.

Maka ihe siri ike nke ihe egwuregwu ụmụaka, akụkụ ike nke PVC bụ p (nke a na-egosipụta site na ọdịnaya nke plasticizer), na ihe siri ike nke TPE na TPR bụ (nke a tụrụ site na data a tụrụ site na onye na-achọpụta ike ike mmiri a).P na a, ụdị isi ike abụọ, nwere mmekọrịta ngbanwe dị nso.

N'ikwu okwu n'ozuzu, mmiri mmiri nke TPE na TPR dị njọ karịa nke PVC.The plasticizing na ịkpụzi okpomọkụ nke TPE na TPR dị elu karịa nke PVC (TPE, TPR plasticizing okpomọkụ bụ 130 ~ 220 ℃, PVC plasticizing okpomọkụ bụ 110 ~ 180 ℃);N'ikwu okwu n'ozuzu, nkwụsị nke PVC dị nro bụ 0.8 ~ 1.3%, TPE na TPR bụ 1.2 ~ 2.0%.

TPE na TPR nwere nguzogide okpomọkụ dị ala karịa PVC.TPE na TPR agaghị esi ike na -40 ℃ na PVC ga-esi ike na - 10 ℃.

Enwere ike ịkpụzi TPE na TPR maka ihe egwuregwu ụmụaka site na ịkpụzi injection, extrusion na ịfụ, ebe PVC nwere ike ịkpụzi site na injection, extrusion, lining na dropping.
