Thermoplastic Rubber (TPR) yog ib hom tshiab ntawm cov khoom siv polymer uas yog cov khoom sib xyaw ntawm cov thermoplastic polymers thiab roj hmab elastomers. TPR muaj cov elasticity ntawm cov roj hmab thiab cov yas ntawm polymers. Nws elastic modulus, tensile lub zog, hnav tsis kam, thiab lwm yam khoom zoo dua li cov yas zoo tib yam, thaum tseem muaj kev ua haujlwm zoo.
Cov ntaub ntawv tseem ceeb ntawm TPR yog polypropylene thiab butadiene roj hmab, thiab qhov sib xyaw ntawm ob cov ntaub ntawv tuaj yeem hloov kho raws li qhov sib txawv ntawm daim ntawv thov scenarios. TPR tuaj yeem ua tiav rau hauv ntau yam duab ntawm cov khoom xws li cov ntsaws ruaj ruaj, kav dej, khau khau, thiab tuav los ntawm extrusion, txhaj tshuaj molding, thiab tshuab molding txoj kev.
TPR muaj cov yam ntxwv hauv qab no:
1. Zoo elasticity thiab yooj, haum rau ntau yam deg duab;
2. Zoo abrasion kuj thiab roj kuj, haum rau siv nyob rau hauv hnyav ua hauj lwm ib puag ncig;
3. Zoo siab thiab tsis kub tsis kam, yuav siv tau nyob rau hauv qhov ntau ntawm -60 degree mus rau 120 degree;
4. Kev ua haujlwm zoo, tuaj yeem ua tiav los ntawm extrusion, txhaj tshuaj molding, thiab lwm yam;
5. Ib puag ncig tus phooj ywg thiab tsis muaj tshuaj lom, ua tau raws li qhov xav tau ntawm ib puag ncig.
TPR muaj ntau yam kev siv, suav nrog kev lag luam tsheb, hluav taws xob, kev kho mob, khoom ua si, thiab khau khau. Hauv kev lag luam tsheb, TPR tuaj yeem siv rau hauv qhov chaw xws li tsheb ntsaws ruaj ruaj, cov kav dej, thiab lub kaw lus ncua, kev txhim kho kev nyab xeeb thiab kev nplij siab ntawm lub tsheb. Hauv kev lag luam hluav taws xob, TPR tuaj yeem siv rau kev rwb thaiv tsev thiab kev tiv thaiv ntawm cov xov hlau thiab cables. Hauv kev lag luam kev kho mob, TPR tuaj yeem siv rau cov ntsaws ruaj ruaj thiab cov khoom siv kho mob, xws li cov tshuaj tua kab mob thiab cov koob txhaj tshuaj.
Hauv cov ntsiab lus, TPR yog hom tshiab ntawm cov khoom siv polymer nrog kev ua tau zoo heev thiab kev cia siab rau daim ntawv thov dav.
