Kodi mumadziwa bwanji za zinthu zoseweretsa za ziweto
Masiku ano, makolo ambiri amachitira ana awo ziweto monga makanda, pofuna kupatsa ana awo zinthu zabwino kwambiri, zosangalatsa, ndiponso zolemera kwambiri. Chifukwa cha kutanganidwa kwa tsiku ndi tsiku, nthawi zina kulibe nthawi yokwanira yocheza nawo kunyumba, kotero kuti zoseweretsa zambiri zidzakonzekera ana aubweya. Makamaka mphira wosamva kulumidwa ndi kuganiza kuti mwana sangakhale ndi nkhawa yopatukana ndipo satopa. Komabe, ndi mitundu yambiri ya zoseweretsa zapulasitiki zomwe zili pamsika, kodi tiyenera kusankha bwanji kukhala otetezeka? Ndi zomwe tikufuna kukambirana nanu lero.
Labala wachilengedwe
Natural labala NR, makamaka hydrocarbon isoprene.
★ Wodziwika ndi kukhathamiritsa kwakukulu, otetezeka komanso opanda poizoni (chidole), mipira yambiri yamtengo wapatali ndi zinthu izi, ngati mtengo wake ndi wotsika mtengo kwambiri, muyenera kukayikira ngati ndi mphira wachilengedwe, komabe, thupi la munthu lidzakhala. matupi awo sagwirizana mphira, ngati mwana wanu amasewera ndi zidole za nkhani imeneyi chifuwa, zikande, etc., musasankhe zidole zimenezi.
neoprene
Neoprene CR, mphira wa neoprene, ndi wamtundu wa mphira wopangira.
★ Amadziwika ndi kukana kwa dzimbiri, kukana kwamafuta ndi kukana kwa mphepo ndi mvula, zomwe nthawi zambiri zimagwiritsidwa ntchito pazoseweretsa zapadera, monga ma hockey ozizira oundana, mtengo wa rabara wopangidwa ndi wokwera kwambiri, umangosewera nyenyezi zitatu chifukwa zoseweretsa zomwe nthawi zambiri zimagwiritsa ntchito mtundu uwu. labala, lidzakhalanso ndi zinthu zina, osati zonse zachilengedwe komanso zopanda poizoni.
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 ndi zinthu 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 zina 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 sizimachotsa mavuto opangira 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, pulasitiki yaikulu ya pulasitiki 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.
