Dab tsi yog Qhov Kev Ua Tau Zoo ntawm Thermoplastic Elastomers?
Thermoplastic Elastomers (TPE) yog cov khoom siv polymer siab heev uas muab cov elasticity ntawm cov roj hmab ib txwm muaj nrog kev ua haujlwm zoo ntawm cov thermoplastics. Vim lawv cov qauv tshwj xeeb thiab kev ua tau zoo sib npaug, TPE cov ntaub ntawv tau siv dav hauv tsheb, kev lag luam, khoom siv, kev kho mob, thiab kev tsim kho. Hauv qab no yog cov lus qhia dav dav ntawm qhov zoo thiab cov kev txwv ntawm cov thermoplastic elastomers.
Dab tsi yogtusQhov zoo ntawm Thermoplastic Elastomers?
Ib qho txiaj ntsig tseem ceeb ntawm TPE yog nws cov txheej txheem ua tau zoo. TPE tuaj yeem ua tiav siv cov khoom siv thermoplastic xws li txhaj tshuaj molding, extrusion, tshuab moulding, compression molding, thiab hloov molding. Qhov no tso cai rau cov tuam txhab siv cov khoom siv yas uas twb muaj lawm yam tsis tas yuav muaj cov khoom siv roj hmab tshwj xeeb vulcanization.
Piv nrog rau kev txhaj tshuaj roj hmab ib txwm siv, TPE tuaj yeem txo lub sijhawm ntau lawm. Thaum ua tiav ntawm cov roj hmab txhaj tshuaj molding tshuab, lub sij hawm vulcanization tuaj yeem luv luv ntawm kwv yees li 20 feeb mus rau tsawg dua 1 feeb, txhim kho cov khoom tsim tau zoo thiab txo cov nqi tsim khoom. Nyob rau hauv daim ntawv thov extrusion, TPE kuj muab ceev extrusion speeds thiab luv luv curing lub sij hawm.
Lwm qhov txiaj ntsig tseem ceeb yog recyclability. Cov khoom khib nyiab tsim tawm thaum lub sijhawm tsim khoom- xws li flash, runners, thiab extrusion pov tseg- tuaj yeem rov ua dua thiab rov siv dua. Txawm tias tom qab - cov neeg siv khoom TPE tuaj yeem rov tsim dua los ntawm cov txheej txheem rov ua dua tshiab, pab txo kev ua qias tuaj ib puag ncig thiab txhim kho kev siv peev txheej. Qhov no ua rau TPE ib puag ncig tus phooj ywg thiab kev xaiv cov khoom siv ruaj khov.
Los ntawm kev xav txog kev siv hluav taws xob, TPE tsis xav tau cov kauj ruam vulcanization, ua rau muaj kev txuag hluav taws xob ntau. Piv txwv li, nyob rau hauv siab - siab hose ntau lawm, cov pa roj hmab siv kwv yees li ntawm 188 MJ / kg, thaum TPE tsuas yog siv 144 MJ / kg, ua tiav kev txuag hluav taws xob ntau dua 25%.
TPE kuj nthuav qhia tus kheej muaj zog- txhawb zog, uas tso cai rau cov qauv yooj yim dua. Qhov kev xav tau ntawm cov khoom sib xyaw ua ke txo qis kev tsim cov txheej txheem nyuaj thiab ua rau cov khoom siv tau yooj yim los tswj thiab tswj. Tsis tas li ntawd, cov thermoplastic elastomers tau qhib txoj hauv kev tshiab rau kev lag luam roj hmab los ntawm kev nthuav dav daim ntawv thov thiab ua kom muaj kev tsim khoom tshiab.
Dab tsi yogtusKev txwv ntawm Thermoplastic Elastomers?
Txawm hais tias nws muaj ntau qhov zoo, TPE muaj qee qhov kev txwv. Nws cov cua kub tsis kam yog feem ntau qis dua li cov roj hmab vulcanized, thiab cov khoom siv kho tshuab yuav poob qis dua thaum kub nce. Qhov no txwv tsis pub nws siv nyob rau hauv siab - qhov chaw kub.
Tsis tas li ntawd, cov khoom xws li compression set, elastic rov qab, thiab ntev - lub sij hawm durability tej zaum yuav qis dua cov tsoos roj hmab hauv tej daim ntawv thov. Los ntawm kev xav txog tus nqi, TPE cov ntaub ntawv feem ntau kim dua li cov roj hmab sib piv.
