Qhov sib txawv ntawm tpr thiab BR roj hmab hauv kev lag luam caster yog tag nrho-encompassing, rau cov neeg uas tsis tau nyob rau hauv kev sib cuag nrog lub network yog tiag tiag nyuaj rau paub qhov txawv, niaj hnub no los ntawm txoj kev xav ua ke nrog cov ntaub ntawv, rau cov phooj ywg los rhuav tshem qhov sib txawv ntawm tpr thiab BR roj hmab hauv qhov tob.
tpr yog cov ntawv luv ntawm Thermo-Plastic-Rubber khoom, peb tuaj yeem xa mus rau nws li cov khoom siv roj hmab thermoplastic. Nws yog cov khoom siv roj hmab thermoplastic uas muaj elasticity tsis muaj vulcanization, thiab tuaj yeem ua tiav thiab molded (xws li txhaj tshuaj molding, extrusion, tshuab molding, thiab lwm yam).
1, kev siv kub ntau -45-90 ℃, feem ntau hais tias tpr cov ntaub ntawv yog raws li SBS substrate, nws cov tshuaj muaj pes tsawg leeg yog raws li nram no: marble kuj, aging kuj feem ntau, kub kuj 70-75 ℃. Yog tias koj xav tau cov ntaub ntawv zoo tiv thaiv kev laus, koj tuaj yeem xaiv SEBS cov ntaub ntawv hloov cov ntaub ntawv.
2, BR roj hmab resilience thiab zoo abrasion kuj, anti-slip thiab poob siab absorbing kev ua tau zoo yog zoo heev, tpr cov ntaub ntawv mos thiab xis kom zoo dua rau roj hmab, tab sis cov khoom tensile zog, qaug zog kuj thiab txhua yam khoom tsis zoo li vulcanized roj hmab.
3, cov yam ntxwv ntawm ib puag ncig, tpr cov ntaub ntawv raws li ib puag ncig tus phooj ywg mos roj hmab, cov khoom siv phom sij tseem ceeb xws li plasticizers phthalates Phthalate, nonylphenol NP, PAHs PAHs nrhiav pom, raws li ROHS, REACH, EN71-3, ASTMF963 ib puag ncig tiv thaiv kev ntsuas cov qauv.
4, cov yam ntxwv hardness, tpr cov khoom tuaj yeem hloov kho hauv Shore hardness 5-100 degrees ntawm nws hardness, SEBS-raws li cov ntaub ntawv hloov kho tuaj yeem hloov kho kom qis dua.
BR roj hmab yog cov khoom siv polymer uas muaj zog heev nrog rov qab deformation, elastic ntawm chav tsev kub, tuaj yeem tsim cov deformation loj nyob rau hauv qhov kev txiav txim ntawm me me sab nraud quab yuam, thiab tuaj yeem rov qab ua lub xeev qub tom qab tshem tawm sab nraud quab yuam. Roj hmab belongs rau tag nrho amorphous polymer, nws cov iav hloov pauv kub (T g) yog qhov tsawg, qhov hnyav molecular feem ntau loj heev, ntau tshaj li ntau pua txhiab.
Saib qhov txawv ntawm TPR casters thiab roj hmab casters:
Muaj ntau yam khoom siv rau lub log nto ntawm casters, xws li TPU casters, PP casters, TPR casters, PU casters, TPE casters, nylon casters, roj hmab casters thiab hais txog.
1, BR roj hmab casters yog softer thiab ntsiag to dua TPR casters.
2, piv nrog tus nqi, roj hmab tsis tuaj yeem siv dua, TPR tuaj yeem siv dua, TPR casters raug nqi tsawg dua BR roj hmab casters.
4, los ntawm qhov pom ntawm kev tiv thaiv ib puag ncig, TPR yog cov khoom siv zoo ib puag ncig, BR roj hmab tsis zoo ib puag ncig.
