Cov yas hoses yog siv dav hauv cov khoom noj, tshuaj, dej khib nyiab, nkoj, tshuaj pleev ib ce thiab lwm yam. Vim nws tus nqi qis, nws nyiam los ntawm cov tuam txhab loj. Xaiv cov khoom raug rau cov yas hoses yog ib qho txuj ci uas cov engineers yuav tsum paub. Kev taw qhia luv luv rau cov yas hoses ntawm TPE, TPU thiab PU, vam tias yuav pab cov neeg siv khoom hauv kev xaiv cov yas hoses.
TPE yog dab tsi?
TPE (Thermoplastic Elastomer) yog cov khoom siv thermoplastic elastomer. Nws tsis tsuas yog muaj lub siab elasticity, siab zog thiab siab resilience ntawm roj hmab, tab sis kuj muaj cov yam ntxwv ntawm kev txhaj tshuaj molding. Nws kuj yog ib puag ncig tus phooj ywg, tsis muaj tshuaj lom thiab muaj kev nyab xeeb, nrog rau ntau yam hardness. Zoo heev colorability, mos kov, huab cua tsis kam, qaug zog kuj thiab kub kuj.
Cov khoom siv TPE muaj kev ua haujlwm zoo heev, tsis tas yuav vulcanization, thiab tuaj yeem rov ua dua los txo cov nqi. Nws tuaj yeem tsim los ntawm kev txhaj tshuaj molding theem nrab, npog thiab sib txuas nrog cov ntaub ntawv matrix xws li PP, PE, PC, PS, thiab ABS, lossis tuaj yeem ua pwm nyias.
PU yog dab tsi?
PU (polyurethane), cov khoom siv polyurethane, yog cov ntawv luv ntawm polyurethane, uas yog ib hom khoom siv polymer. PU yog cov khoom siv organic polymer uas tau tshwm sim, lub npe hu ua "plas loj thib tsib", thiab tau siv dav hauv ntau lub teb chaws kev lag luam vim nws qhov kev ua tau zoo heev.
Daim ntawv thov teb ntawm PU cov khoom siv yog laser, suav nrog riam teeb kev lag luam, tshuaj lom neeg kev lag luam, hluav taws xob, textile, kho mob, kev tsim kho, cov ntaub ntawv hauv tsev, tsheb, kev tiv thaiv teb chaws, aerospace, aviation, thiab lwm yam.
TPU yog dab tsi?
PU tau hais los saum toj no yog cov khoom siv raw rau kev tsim TPU. PU tuaj yeem muab faib ua: CPU (cam khwb cia polyurethane elastomer), TPU (thermoplastic polyurethane elastomer), MPU (mixed polyurethane elastomer) raws li kev siv tshuab.
TPU (Thermoplasticpolyurethanes) lub npe yog thermoplastic polyurethane elastomer roj hmab, uas yog muab faib ua ob hom: polyester hom thiab polyether hom. Vim tias TPU muaj ntau yam hardness (60HA{1}}HD), hnav tsis kam, roj tsis kam, pob tshab, thiab elasticity zoo, nws tau siv dav, xws li cov khoom siv niaj hnub, cov khoom ua si, cov khoom ua si, cov khoom siv kho kom zoo nkauj, thiab lwm yam. .
Nws yog ib qho tsim nyog hais tias ntau qhov chaw yuav tsum tau ua kom tau raws li kev tiv thaiv ib puag ncig, thiab cov khoom siv PVC yuav tsis ua raws li qhov yuav tsum tau ua, yog li cov nplaim hluav taws tsis muaj halogen TPU tuaj yeem hloov tau zoo.
Qhov txawv ntawm TPE thiab TPU yog dab tsi?
1. Incineration: TPE cov ntaub ntawv muaj ib tug qab ntxiag aroma thaum incinerated, thaum TPU khoom belongs rau polyurethane, uas muaj ib tug me ntsis rau cov tsw ntawm ammonia. Nyob rau tib lub sijhawm, muaj lub suab nrov me ntsis thaum TPU yog incinerated;
2. Lub zog thiab hnav tsis kam: TPU muaj lub zog siab thiab zoo hnav tsis kam, uas yog pom tseeb zoo dua li cov khoom siv TPE;
3. Softness: TPE cov ntaub ntawv muaj ntau yam hardness (0A-90A), thaum TPU cov ntaub ntawv muaj ib tug qis hardness saum 60A, yog li TPE cov ntaub ntawv zoo dua, thiab TPU cov ntaub ntawv xav harder.
