Me yasa Masu Kera Kayan Wasan Dabbobi Ke Zaɓan Kayan TPR?

TPR wani nau'i ne na polymer mai laushi tare da kayan haɓakawa.Dangane da buƙatun daban-daban na abokan ciniki, masu ba da kaya suna ba da tsarin tsarin tsarin kayan TPE da TPR da aka yi niyya da mafita na aikace-aikacen.Ƙarfin ƙarfin R & D shine muhimmin mahimmanci don kimanta ƙarfin ƙarfin TPE da masana'antun TPR.

Me yasa yawancin masana'antun kayan wasan dabbobi suka zaɓi kayan TPE maimakon kayan PVC, na farko shine kariyar muhalli.TPE da TPR ba su ƙunshi phthalate plasticizer da halogen ba, kuma konewar TPE da TPR ba sa sakin dioxin da sauran abubuwa masu cutarwa.

Don taurin kayan wasan dabbobi, sashin taurin PVC shine p (wanda aka bayyana ta abun ciki na filastik), kuma sashin taurin TPE da TPR shine (ana auna ta bayanan da aka auna ta mai gwada taurin bakin ruwa a).P da a, nau'ikan taurin kai biyu, suna da kusancin juzu'i.

Gabaɗaya magana, ƙarancin TPE da TPR ya fi na PVC muni.A plasticizing da gyare-gyaren zafin jiki na TPE da TPR ne mafi girma fiye da na PVC (TPE, TPR plasticizing zafin jiki ne 130 ~ 220 ℃, PVC plasticizing zafin jiki ne 110 ~ 180 ℃);Gabaɗaya magana, raguwar PVC mai laushi shine 0.8 ~ 1.3%, TPE da TPR sune 1.2 ~ 2.0%.

TPE da TPR suna da mafi kyawun juriya na zafin jiki fiye da PVC.TPE da TPR ba za su taurare a -40 ℃ da PVC za su taurare a - 10 ℃.

TPE da TPR na dabbobin wasan yara za a iya ƙera su ta hanyar allura gyare-gyare, extrusion da busa gyare-gyare, yayin da PVC za a iya gyare-gyare ta hanyar allura, extrusion, rufi da faduwa.
