Umahluko phakathi kwe-BR zerabha casters kunye ne-TPR casters

Umahluko phakathi kwe-tpr kunye ne-BR irabha kwishishini le-caster liquka konke, kuba abo bangazange badibane nothungelwano kunzima ngokwenene ukuhlula, namhlanje kwi-theory edibeneyo kunye necala, ukuba abahlobo baphule umahluko phakathi tpr kunye BR irabha ngobunzulu.

I-tpr sisishunqulelo semathiriyeli ye-Thermo-Plastic-Rubber, sinokubhekisela kuyo njengemathiriyeli yerabha ye-thermoplastic. Yinto yerubha ethambileyo ye-thermoplastic ene-elasticity ngaphandle kwe-vulcanization, kwaye inokucutshungulwa ngokuthe ngqo kwaye ibunjwe (njengokubumba inaliti, i-extrusion, i-blow molding, njl.).

1, ukusetyenziswa koluhlu lobushushu -45-90 ℃, ngokuqhelekileyo wathi tpr impahla isekelwe SBS substrate, iimpawu zayo imichiza ngolu hlobo lulandelayo: ukumelana marble, ukumelana ukwaluphala ngokubanzi, ukumelana lobushushu 70-75 ℃. Ukuba ufuna izinto ezintle zokumelana nobushushu bokwaluphala, ungakhetha isiseko se-SEBS imathiriyeli elungisiweyo.

I-2, ukomelela kwe-rabha ye-BR kunye nokuchasana okuhle kwe-abrasion, ukuchasana nokutyibilika kunye nokusebenza kothusayo kugqwesileyo, izinto ze-tpr zithambile kwaye zikhululekile ukuba ziphakame kunerabha, kodwa amandla okuqina, ukumelana nokudinwa kunye neepropathi zoomatshini azilunganga njengerabha evulziweyo.

I-3, iimpawu zokusingqongileyo, izinto ze-tpr njengerabha ethambileyo ehambelana nokusingqongileyo, ezona zinto ziyingozi njengeplasticizers phthalates Phthalate, nonylphenol NP, PAHs PAHs ubhaqo, ngokuhambelana ne-ROHS, REACH, EN71-3, ASTMF963 imigangatho yokuvavanya ukhuseleko lokusingqongileyo.

I-4, iimpawu zobunzima, izinto ze-tpr zinokuhlengahlengiswa kwi-Shore hardness 5-100 degrees of its hardness, izinto eziguqulwayo ezisekelwe kwi-SEBS zinokutshintshwa kwi-hardness ephantsi.

Irabha ye-BR sisixhobo sepolymer esinwebekayo esinokuguqulwa umva, i-elastic kwiqondo lobushushu begumbi, inokuvelisa i-deformation enkulu phantsi kwesenzo samandla amancinci angaphandle, kwaye inokubuyisela imeko yangaphambili emva kokususa amandla angaphandle. Irabha yeyepolymer amorphous ngokupheleleyo, iqondo lobushushu iglasi yayo (T g) iphantsi, ubunzima molekyuli idla ngokuba mkhulu kakhulu, ngaphezu kwamakhulu amawaka.

Jonga umahluko phakathi kwe-TPR casters kunye ne-rubber casters:

Zininzi izixhobo zomphezulu wamavili we-casters, ezinje nge-TPU casters, i-PP casters, i-TPR casters, i-PU casters, i-TPE casters, i-nylon casters, i-rubber casters njalo njalo.

I-1, i-BR i-rubber casters ithambile kwaye ithule kune-TPR casters.

I-2, xa kuthelekiswa neendleko, irabha ayinakuphinda isetyenziswe, i-TPR inokuphinda isetyenziswe, i-TPR casters ixabisa ngaphantsi kwe-BR zerabha casters.

I-4, ukusuka kwindawo yokujonga ukukhuselwa kwendalo, i-TPR yinto entsha ehambelana nokusingqongileyo, i-rubber ye-BR ayihambisani nokusingqongileyo.
