Chifukwa Chiyani Opanga Toy Toy Amasankha Zida za TPR?

TPR ndi mtundu wa polima wofewa wokhala ndi mawonekedwe osinthika.Malinga ndi zofunikira zosiyanasiyana zamakasitomala, ogulitsa amapereka njira zowunikira za TPE ndi TPR ndi mayankho ogwiritsira ntchito.Kulimba kwa R&D ndi gawo lofunikira pakuwunika mphamvu zonse za opanga TPE ndi TPR.

Chifukwa chiyani opanga zoseweretsa za ziweto zambiri amasankha zinthu za TPE m'malo mwa PVC, choyamba ndikuteteza chilengedwe.TPE ndi TPR zilibe phthalate plasticizer ndi halogen, ndipo kuyaka kwa TPE ndi TPR sikutulutsa dioxin ndi zinthu zina zovulaza.

Pa kuuma kwa zoseweretsa za ziweto, gawo la kuuma la PVC ndi p (lowonetsedwa ndi zomwe zili mu plasticizer), ndipo gawo la kuuma la TPE ndi TPR ndi (loyesedwa ndi deta yoyesedwa ndi shore hardness tester a).P ndi a, mitundu iwiri ya kuuma, amakhala ndi ubale wongotembenuka mtima.

Nthawi zambiri, kutsekemera kwa TPE ndi TPR kumakhala koyipa kuposa kwa PVC.The plasticizing ndi akamaumba kutentha kwa TPE ndi TPR ndi apamwamba kuposa PVC (TPE, TPR plasticizing kutentha ndi 130 ~ 220 ℃, PVC plasticizing kutentha ndi 110 ~ 180 ℃);Nthawi zambiri, kuchepa kwa PVC yofewa ndi 0,8 ~ 1.3%, TPE ndi TPR ndi 1.2 ~ 2.0%.

TPE ndi TPR zili ndi kutentha kochepa kwambiri kuposa PVC.TPE ndi TPR sizidzaumitsa pa - 40 ℃ ndipo PVC idzauma pa - 10 ℃.

TPE ndi TPR zoseweretsa za ziweto zimatha kupangidwa ndi jekeseni, kutulutsa ndi kupukuta, pamene PVC ikhoza kupangidwa ndi jekeseni, extrusion, lining and dropped.
