Hobaneng ha Baetsi ba Toy Toy ba Khetha Lisebelisoa tsa TPR?

TPR ke mofuta oa polymer e bonolo e nang le thepa ea modulation.Ho latela litlhoko tse fapaneng tsa bareki, barekisi ba fana ka sistimi ea thepa e shebiloeng ea TPE le TPR le tharollo ea ts'ebeliso.Matla a bokhoni ba R & D ke ntlha ea bohlokoa ho lekola matla a felletseng a baetsi ba TPE le TPR.

Ke hobane'ng ha baetsi ba lipapali tsa liphoofolo tse ruuoang lapeng ba khetha thepa ea TPE ho e-na le thepa ea PVC, ea pele ke tšireletso ea tikoloho.TPE le TPR ha li na phthalate plasticizer le halogen, 'me ho chesa ha TPE le TPR ha ho lokolle dioxin le lintho tse ling tse kotsi.

Bakeng sa boima ba lipapali tsa liphoofolo tse ruuoang lapeng, yuniti ea boima ba PVC ke p (e hlahisoang ke litaba tsa plasticizer), 'me karolo ea boima ba TPE le TPR ke (e lekantsoeng ke data e lekantsoeng ka shore hardness tester a).P le a, mefuta e 'meli ea ho thatafala, e na le kamano e haufi ea ho sokoloha.

Ka kakaretso, metsi a TPE le TPR a mpe ho feta a PVC.Mocheso oa polasetiki le oa ho bōpa oa TPE le TPR o phahame ho feta oa PVC (TPE, TPR plasticizing mocheso ke 130 ~ 220 ℃, mocheso oa PVC oa polasetiki ke 110 ~ 180 ℃);ka kakaretso, ho honyela ha PVC e bonolo ke 0.8 ~ 1.3%, TPE le TPR ke 1.2 ~ 2.0%.

TPE le TPR li na le ho hanyetsa mocheso o tlase ho feta PVC.TPE le TPR li ke ke tsa thatafala ho - 40 ℃ le PVC e tla thatafala ho - 10 ℃.

TPE le TPR bakeng sa lipapali tsa liphoofolo tse ruuoang lapeng li ka bōptjoa ka ho bōptjoa ka ente, extrusion le blowing, ha PVC e ka bōptjoa ka ente, extrusion, linening le dropping.
