I-TPU (i-Thermoplastic polyurethanes) yimathiriyeli phakathi 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 yokuthatha indawo ye-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 i-elasticity ephezulu kwiqondo lokushisa -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 kwandisa ngeqondo lokushisa. kwakhona iphantsi kunaleyo yemathiriyeli 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 yezona zinto zikhethwayo kwiimveliso ezixhathisayo.
