PET — Los ntawm kev txhim kho tus neeg sawv cev nucleating, tus neeg sawv cev crystallizing thiab iav fiber reinforcement, PET muaj cov yam ntxwv hauv qab no ntxiv rau cov khoom ntawm PBT.
1. Qhov kub distortion kub thiab kev siv lub sij hawm ntev yog qhov siab tshaj plaws ntawm cov thermoplastic general engineering yas.
2. Vim nws qhov kub tsis kam, PET reinforced yog immersed nyob rau hauv ib tug solder da dej ntawm 250 ° C rau 10s, thiab nws hardly deforms los yog hloov xim. Nws yog tshwj xeeb tshaj yog haum rau kev npaj ntawm soldered hluav taws xob thiab hluav taws xob qhov chaw.
3. Lub zog dabtsi yog khoov yog 200MPa, lub elastic modulus yog 4000MPa, lub creep kuj thiab qaug zog kuj kuj zoo heev, lub hardness saum npoo yog siab, thiab txhua yam khoom zoo ib yam li cov thermosetting plastics.
4. Vim tias tus nqi ntawm ethylene glycol siv los tsim PET yog yuav luag ib nrab pheej yig dua li ntawm butanediol siv los tsim PBT, PET resin thiab reinforced PET yog tus nqi qis tshaj ntawm engineering plastics thiab muaj nqi siab.
PP-Polypropylene (PP yas) yog lwm cov khoom siv zoo heev tsim tom qab nylon. Nws yog linear polymer nrog siab ceev, tsis muaj sab saw thiab siab crystallinity, thiab muaj cov khoom zoo heev. Dawb translucent, waxy thaum unpigmented; lighter tshaj polyethylene. Lub pob tshab kuj zoo dua li ntawm polyethylene, thiab nws nyuaj dua li polyethylene.
CovPET thiab PP broom filament extruding tshuab kabtsim thiab tsim los ntawm Qingdao Zhuoya Machinery tuaj yeem ua ob qho tib si zoo PET broom filament thiab PP broom filament, yog li peb cov kab tshuab tau txais tos los ntawm cov neeg siv khoom thoob plaws ntiaj teb.
