TPR pulasitiki
TPR ndi zida za mphira za thermoplastic, ndipo zoseweretsa zambiri wamba zimawonetsa kuti ndi TPR.
★ Imadziwika ndi nthawi imodzi kuumba, palibe chifukwa cha vulcanization, elasticity yabwino, ndipo pakali pano ndi chinthu chachikulu chotsika mtengo pamsika, zomwe zikutanthauza kuti izi ndizinthu zopangidwa osati zachilengedwe, kaya ndi poizoni zimadalira. kupanga, sankhani wopanga nthawi zonse.
PVC pulasitiki
PVC polyvinyl chloride, pulasitiki yopangira.
★ Zinthu zake ndi zofewa, zopangidwa ndi pulasitiki, komanso zapoizoni.
PC pulasitiki
PC, polycarbonate.
★ Imatha kukonza zoseweretsa zakuthupi zolimba, zosakoma komanso zopanda fungo, koma zimatha kutulutsa zinthu zapoizoni za BPA, zoseweretsa zapakhomo zokhala ndi ma PC ambiri, ndibwino kusankha wopanda BPA posankha.
ABS pulasitiki
ABS, acrylonitrile-butadiene-styrene pulasitiki.
★ Zosagonjetsedwa ndi kugwa ndi kuwomba, zolimba, zoseweretsa zina zowonongeka zidzagwiritsa ntchito nkhaniyi, zambiri za ABS ndizotetezeka komanso zopanda poizoni, koma sizikulepheretsani mavuto a kukonza ndi kupanga.
PE ndi PP mapulasitiki
PE, polyethylene;PP, polypropylene, mapulasitiki onsewa ndi mapulasitiki opanda fungo komanso osawopsa.
★ Kutentha kochepa ndi kukana kutentha kuli bwino, ndizochepa poizoni kuposa PVC, ndipo kubwezeretsanso kumakhala kosavuta, mankhwala ambiri a ana adzagwiritsa ntchito nkhaniyi, zinthu zazikulu zapulasitiki mwina ndi magulu awa, makolo posankha zidole za ana a tsitsi zakuthupi, pambuyo pa zonse, zoseweretsazi zimalumidwa mkamwa tsiku lililonse, nthawi zina zimamezedwa mwangozi.Koma kunena za izi, posewera ndi zidole za pulasitiki, makamaka masewera a mpira, ndi bwino kutsagana ndi makolo, mwayi woopsa, osatchova njuga.
