Qhov sib txawv ntawm tpr thiab BR roj hmab hauv kev lag luam caster yog txhua yam-encompassing, rau cov neeg uas tsis tau sib cuag nrog lub network yog qhov nyuaj heev rau qhov sib txawv, hnub no los ntawm kev xav ua ke nrog rooj plaub, rau cov phooj ywg kom tawg qhov sib txawv ntawm tpr thiab BR roj hmab hauv qhov tob.
TPR yog lub npe luv ntawm cov khoom siv Thermo-Plastic-Rubber, peb tuaj yeem xa mus rau nws ua cov khoom siv roj hmab thermoplastic. Nws yog cov khoom siv roj hmab thermoplastic mos nrog elasticity tsis muaj vulcanization, thiab tuaj yeem ua tiav thiab pwm ncaj qha (xws li kev txhaj tshuaj molding, extrusion, tshuab molding, thiab lwm yam).
1, kev siv qhov kub thiab txias -45-90 ℃, feem ntau hais tias cov khoom siv tpr yog raws li SBS substrate, nws cov khoom siv tshuaj lom neeg yog raws li nram no: marble tsis kam, kev laus tsis kam feem ntau, kub tsis kam 70-75 ℃. Yog tias koj xav tau cov khoom siv tiv thaiv kev laus zoo, koj tuaj yeem xaiv cov khoom siv hloov kho SEBS.
2, BR roj hmab resilience thiab zoo abrasion tsis kam, anti-plam thiab shock absorption kev ua tau zoo heev, tpr khoom mos thiab xis nyob kom zoo dua roj hmab, tab sis cov khoom tensile zog, qaug zog tsis kam thiab cov khoom siv kho tshuab tsis zoo li roj hmab vulcanized.
3, cov yam ntxwv ib puag ncig, cov khoom siv tpr ua cov roj hmab mos mos uas zoo rau ib puag ncig, cov tshuaj phom sij tseem ceeb xws li cov yas phthalates Phthalate, nonylphenol NP, PAHs PAHs nrhiav tau, ua raws li ROHS, REACH, EN71-3, ASTMF963 cov qauv kev tiv thaiv ib puag ncig.
4, cov yam ntxwv ntawm qhov nyuaj, cov khoom siv tpr tuaj yeem hloov kho hauv Shore hardness 5-100 degrees ntawm nws qhov nyuaj, SEBS-raws li cov ntaub ntawv hloov kho tuaj yeem hloov kho kom qis dua qhov nyuaj.
Roj hmab BR yog cov khoom siv polymer uas muaj zog heev thiab hloov pauv tau, nws yooj ywm thaum kub hauv chav, thiab nws tuaj yeem tsim cov kev hloov pauv loj hauv qab lub zog me me sab nraud, thiab nws tuaj yeem rov qab tau lub xeev qub tom qab tshem tawm lub zog sab nraud. Roj hmab yog cov polymer amorphous kiag li, nws qhov kub hloov iav (Tg) qis, thiab qhov hnyav molecular feem ntau loj heev, ntau dua ntau pua txhiab.
Saib qhov sib txawv ntawm TPR casters thiab roj hmab casters:
Muaj ntau yam khoom siv rau lub log nto ntawm cov casters, xws li TPU casters, PP casters, TPR casters, PU casters, TPE casters, nylon casters, roj hmab casters thiab lwm yam.
1, BR roj hmab casters yog softer thiab ntsiag to dua li TPR casters.
2, piv rau tus nqi, roj hmab tsis tuaj yeem rov ua dua tshiab, TPR tuaj yeem rov ua dua tshiab, TPR casters pheej yig dua li BR roj hmab casters.
4, los ntawm qhov pom ntawm kev tiv thaiv ib puag ncig, TPR yog cov khoom siv tshiab uas zoo rau ib puag ncig, roj hmab BR tsis zoo rau ib puag ncig.
