1. Ntawm cov thermoplastic general engineering plastics, thermal deformation kub thiab kev siv lub sij hawm ntev yog siab.
2. Reinforced PET, vim nws cov cua kub tsis kam, yog immersed nyob rau hauv lub brazing da dej ntawm 250 rau 10S, hardly deformed los yog discolored, thiab yog tshwj xeeb tshaj yog haum rau kev npaj ntawm hluav taws xob thiab hluav taws xob qhov chaw rau brazing.
3. Lub zog dabtsi yog khoov yog 200 MPa, lub elastic modulus yog 4000 MPa, lub creep kuj thiab qaug zog kev ua tau zoo kuj zoo heev, lub hardness saum npoo yog siab, thiab cov neeg kho tshuab zog zoo ib yam li cov thermosetting plastics. 4. Txij li thaum tus nqi ntawm ethylene glycol siv nyob rau hauv PET ntau lawm yuav luag ib nrab pheej yig dua li butanediol siv nyob rau hauv PBT ntau lawm, PET resin thiab reinforced PET yog tus nqi qis ntawm engineering plastics thiab muaj nqi siab.
Yog li ntawd, thaum xaiv cov ntawv PET los ua cov rooj tog zaum, nco ntsoov yuav los ntawm cov npe tsis tu ncua, txhawm rau xyuas kom zoo dua hauv kev siv. Thaum peb xaiv yuav, peb yuav tsum kawm paub qhov txawv ntawm qhov tseeb thiab qhov tsis tseeb.
