PBT ndiye chidule cha polybutchlene terephthalate. Amawerengedwa mu mndandanda wa polysister. Imapangidwa ndi 1.4-teronene glycol ndi terephthalic acid (TPAphthalate (DMT). Ndi trawys translucence to opaque, ma crystalline polyester polyester imapangidwa kudzera mu njira yophatikizira. Pamodzi ndi chiweto, imaphatikizidwa mokweza polroyeter polyester, kapena modester.
Mawonekedwe a PBT Plastics
1. Kusinthasintha kwa pulasitiki ya PBT ndiyabwino kwambiri ndipo kumakuthandizaninso kugwa, ndipo kusokonekera kwake kulibe mphamvu.
2. PBT siili ngati yoyaka ngati mapulaneti wamba. Kuphatikiza apo, ntchito yake yodzikuza ndi yamagetsi imakhala yokwera pulasitiki iyi, motero mtengo wake ndi wokwera mtengo pakati pa pulasitiki.
3. Madzi oyamwa madzi a PBT ali otsika kwambiri. Mapulasi wamba amasanduka mosavuta m'madzi ndi kutentha kwambiri. PBT ilibe vuto ili. Itha kugwiritsidwa ntchito kwa nthawi yayitali ndikukhalabe ndi luso labwino kwambiri.
4. Pamwamba pa PBT ndi yosalala kwambiri komanso yopanda tanthauzo yocheperako, yomwe imapangitsa kuti ikhale yabwino kugwiritsa ntchito. Ilinso chifukwa chakuti kukopeka kwake ndi kochepa, kotero nthawi zambiri kumagwiritsidwa ntchito nthawi zambiri pomwe kuchepa kwa mikaliro kuli kwakukulu.
5. PBT pulasitiki ili ndi mphamvu kwambiri malinga ngati zimapangidwa, ndipo zimangokhala kulondola kwapamwamba, motero ndi zinthu zapamwamba kwambiri. Ngakhale mu mankhwala ochulukirapo, imatha kukhalabe ndi boma loyambirira, kupatula zinthu zina monga ma asidi olimba komanso zitsulo zolimba.
6. Ambiri ndi abwino kwambiri, koma zida za PBB sizili. Katundu wake woyenda ndi wabwino kwambiri, ndipo katundu wake amagwira ntchito bwino ataumba. Chifukwa zimatengera ukadaulo wa polymer zosokoneza bongo, zimakwaniritsa malo ena a Aloy omwe amafuna polymer.
Akuluakulu a PBT
1. Chifukwa cha mphamvu yake yathupi ndi mankhwala, ptt nthawi zambiri imagwiritsidwa ntchito ngati zinthu zopitilira muyeso wachiwiri wa ulusi wam'maso mu chilombo chapansi panja.

3. Magawo ofunsira a Stoo Service: Zigawo zamkati monga mabatani a wiper, ma stormu a Storces, etc.; Zigawo zamagetsi ndi zamagetsi monga magalimoto amayandikitsira matope opindika komanso zolumikizira zamagetsi.
