Njengenxalenye ebalulekileyo yezixhobo ezahlukeneyo, ifenitshala kunye nezixhobo, izinto kunye nokusebenza kwee-casters kunempembelelo enkulu kumgangatho kunye nokusebenza kwemveliso iyonke. Phakathi kweentlobo ezininzi zee-casters, ii-TPR casters kunye nee-BR raber casters zikhetho ezimbini eziqhelekileyo. Namhlanje kuza kubakho uthelekiso oluneenkcukacha lomahluko phakathi kwezi ntlobo zimbini ze-BR kunye nee-tpr casters.
Izixhobo kunye neePropati
Okokuqala, ii-TPR casters zenziwe ngerabha ye-thermoplastic (TPR), into ye-thermoplastic enokuqina kwerabha, engadingi kuguqulwa ibe yi-vulcanized kwaye inobuhlobo nokusingqongileyo, ayinatyhefu, kwaye inemibala eqaqambileyo. Ngenxa yokuqina kwayo kunye nokumelana nokugruzuka kwezinto ze-TPR, ii-TPR casters zihlala zinokumelana okuhle nokugruzuka, ioyile kunye nemozulu.
Ngokwahlukileyo koko, ii-BR rubber casters zenziwe ngerabha ye-butadiene (BR), irabha eyenziweyo eyenziwe nge-polymerization yee-butadiene monomers, enesakhiwo se-molecular esifana neserabha yendalo. Irabha ye-BR inokuqina okuhle, ukumelana nokukrweleka, ukumelana nokubanda, kunye nokumelana nokuguqa.
Ukucubungula kunye nokusebenza
Ukusebenza kakuhle kwezinto ze-TPR kubhetele kunezerabha, kwaye zinokucutshungulwa ngezixhobo eziqhelekileyo zokucubungula i-thermoplastic ngaphandle konyango olukhethekileyo lwe-vulcanization. Oku kwenza ii-TPR casters zisebenze kakuhle kwaye zingabizi kakhulu ukuzivelisa.
Nangona kunjalo, ii-BR raber casters zibalasele ekusebenzeni ngokuguquguqukayo, ingakumbi kubushushu obuphezulu. I-BR raber inokumelana nokukrazuka okugqwesileyo, ukumelana nokubhoboka, kunye nokumelana nokukrazuka okuguquguqukayo, okuvumela ii-BR raber casters ukuba zihlale zisebenza kakuhle kwiindawo ezinzima.
Ukhuseleko nokusingqongileyo
Ngokuphathelele ukhuseleko lokusingqongileyo, izinto ze-TPR zinenzuzo: I-TPR yinto enobuhlobo nokusingqongileyo kwaye ayinabungozi ehambelana ne-ROHS, i-REACH kunye neminye imigangatho yokusingqongileyo, kwaye ingasetyenziswa kakhulu kwizixhobo zonyango, izinto zokudlala zabantwana nakwezinye iindawo. Ngokwahlukileyo koko, nangona irabha ye-BR ikwayinto enobuhlobo nokusingqongileyo, inokuthintelwa yimigaqo yokusingqongileyo kwiimeko ezithile zokusetyenziswa.
Xa kukhethwa ii-casters, kufuneka kuqwalaselwe ngokubanzi ngokusekelwe kwizinto ezifana neemeko ezithile zokusetyenziswa, iimfuno zokusebenza kunye nemigaqo yokusingqongileyo. Umzekelo, ii-casters ze-TPR zinokuba lukhetho olungcono kwiimeko ezifuna imveliso ephezulu, iindleko eziphantsi kunye neemfuno eziphezulu zokusingqongileyo, ngelixa ii-casters zerabha ze-BR zinokuba zifanelekile ngakumbi kwiimeko zokusetyenziswa ezifuna ukusebenza okuphezulu kwamandla kunye nokumelana nobushushu obuphezulu.
