Farqiga u dhexeeya tpr iyo BR rubber ee warshadaha wax-soo-saarka ayaa ah mid dhan walba leh, kuwa aan la xiriirin shabakadda runtii way adag tahay in la kala saaro, maanta aragtida lagu daray kiiska, saaxiibbada si ay u kala saaraan farqiga u dhexeeya tpr iyo BR caag qoto dheer.
tpr waa soo gaabinta walxaha Thermo-Plastic-Rubber, waxaan u tixraaci karnaa walxo caag ah oo heerkulbeeg ah.Waa shey caag jilicsan oo heerkulbeeg ah oo leh dabacsanaan la'aan, waxaana si toos ah loo farsameyn karaa oo loo qaabeyn karaa (sida qaabaynta duritaanka, extrusion, dharbaaxada, iwm.).
1, isticmaalka kala duwan heerkulka -45-90 ℃, sida caadiga ah ayaa sheegay in wax tpr ku salaysan yahay substrate SBS, sifooyinka kiimikada ay yihiin sida soo socota: caabbinta marmar, caabbinta gabowga guud ahaan, iska caabin heerkulka 70-75 ℃.Haddii aad u baahan tahay qalabka iska caabbinta heerkulka gabowga wanaagsan, waxaad dooran kartaa walxaha saldhigga SEBS ee la beddelay.
2, caabbinta caag BR iyo caabbinta abrasion wanaagsan, anti-slip iyo waxqabadka nuugista shoogga waa mid aad u fiican, tpr wax jilicsan oo raaxo leh in ay ka sarreeyaan caag, laakiin xoogga jilicsanaanta walxaha, caabbinta daalka iyo sifooyinka farsamada ma aha sida ugu fiican sida caag vulcanized ah.
3, sifooyinka deegaanka, tpr walxaha sida caag jilicsan deegaanka saaxiibtinimo, walxaha ugu muhiimsan ee khatarta ah sida plasticizers phthalates Phthalate, nonylphenol NP, PAHs ogaanshaha PAHs, waafaqsan ROHS, REACH, EN71-3, ASTMF963 heerka imtixaanka ilaalinta deegaanka.
4, sifooyinka qallafsanaanta, walxaha tpr waxaa lagu hagaajin karaa adkaanta Shore 5-100 ee adkaanteeda, SEBS-ku-salaysan walxaha wax laga beddelay ayaa lagu hagaajin karaa qallafsanaanta hoose.
caag BR waa qalab aad u jilicsan oo polymer ah oo leh qallafsanaan la beddeli karo, laastikada heerkulka qolka, wuxuu soo saari karaa isbeddel weyn oo hoos yimaada ficilka xoogga yar ee dibadda, wuxuuna dib u soo celin karaa xaaladdii asalka ahayd ka dib markii laga saaro xoogga dibadda.Rubber waxaa iska leh polymer-ka gebi ahaanba amorphous, heerkulkeeda kala-guurka galaas (T g) waa hooseeyaa, miisaanka kelli waa inta badan aad u weyn, in ka badan boqollaal kun.
Fiiri faraqa u dhexeeya shubayaasha TPR iyo caagagga:
Waxaa jira waxyaabo badan oo loogu talagalay dusha sare ee taayirrada, sida TPU casters, PP casters, TPR casters, PU casters, TPE casters, naylon casters, caag ka samaysan iyo wixii la mid ah.
1, Rabadhka BR BR ayaa ka jilicsan oo ka aamusan kuwa wax shubaya TPR.
2, marka la barbar dhigo kharashka, caag dib loo warshadayn karo lama samayn karo, TPR dib ayaa loo warshadayn karaa, shubayaasha TPR waxay ku kacayaan wax ka yar BR caag.
4, marka laga eego dhinaca ilaalinta deegaanka, TPR waa walxo cusub oo deegaanka u wanaagsan, caag BR ma aha mid deegaan ahaan u fiican.
