I-TPU (i-Thermoplastic polyurethanes) yinto ephakathi kwerabha kunye neplastiki.Izinto eziphathekayo zi-oyile kunye namanzi kwaye zinomthwalo obalaseleyo wokuthwala kunye nokuchasana kwempembelelo.I-TPU sisixhobo sepolymer esingenabungozi kokusingqongileyo.Izinto ze-Tpu zineenzuzo ze-elasticity ephezulu yerabha kunye nokusebenza kweplastiki.Ayifuni i-vulcanization kwaye inokucutshungulwa ngoomatshini bokubumba abaqhelekileyo be-thermoplastic.Ukubeka ngokulula, i-thermoplastic elastomer tpu i-thermoformed kwaye inokuveliswa kusetyenziswa oomatshini bokubumba inaliti, ii-extruders, oomatshini bokubumba.I-Scrap kunye ne-recyclable yi-100% enokuphinda isetyenziswe, into ekrwada ekhethiweyo yokutshintsha i-PVC, i-rubber kunye ne-silicone kwaye ilawule i-rubber kunye ne-plastiki ishishini.
Irabha: Irabha yipolymer ephilayo enobunzima bemolekyuli obungamakhulu amawaka.Unyango lwe-Vulcanization luyafuneka ukugcina ukunwebeka okuphezulu kuluhlu lobushushu obuphakathi kwe -50 ukuya kwi-150 °C.I-modulus e-elastic ephantsi, ii-odolo ezi-3 zobukhulu obuphantsi kunezixhobo eziqhelekileyo, i-deformation enkulu, i-elongation inokufikelela kwi-1000% (izinto eziqhelekileyo zingaphantsi kwe-1%), ubushushu bukhutshwa ngexesha lenkqubo yokwelula, kwaye u-elasticity unyuka ngobushushu, obuphantsi. kunoko kwemathiriyeli jikelele ngokuchaseneyo.
Umahluko phakathi kwe-TPU kunye nerabha:
1. I-Rubber ithambile, kwaye uluhlu lobunzima (0-100a) lwempahla ye-tpu lubanzi kakhulu phakathi kwerabha kunye neplastiki;
2. Ingqikelelo ye-elastomer ibanzi kakhulu, i-tpu ikwabizwa ngokuba yirubha ye-thermoplastic (tpr), kwaye irabha ngokuqhelekileyo ibhekisela kwirubha ye-thermosetting;
3. Iindlela zokucubungula zahlukile.I-Rubber icutshungulwa ngokuxuba i-rubber, ngelixa i-TPU idla ngokuqhutyelwa nge-extrusion;
4. Iimpawu zahlukile.Irabha idla ngokufuna ukongeza izongezo ezahlukahlukeneyo kwaye ifuna ukuvuthwa ukuze kuqiniswe, ngelixa ukusebenza kwe-tpu ye-thermoplastic elastomers kulungile kakhulu;
5. I-tpu ye-elastomer ye-thermoplastic inesakhiwo somgca kwaye idibaniswe ngokomzimba nge-hydrogen bonding.Iibhondi zeHydrogen ziyaqhawuka kumaqondo obushushu aphezulu kwaye ziyiplastiki.Irabha iqhagamshelwe ngokwekhemikhali kwaye hayi i-thermoplastic.
6. Izinto zeplastiki ze-TPU zinokumelana okugqwesileyo kokunxiba, okungaphezulu kokuphindwe kahlanu kwerabha yendalo, kwaye yenye yezinto ezikhethwayo kwiimveliso ezixhathisayo.
