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 elasticity mkulu, otetezeka ndi sanali poizoni (chidole mlingo), ambiri a mtengo mtengo mipira zambiri zakuthupi, ngati mtengo ndi wotchipa kwambiri, muyenera kukayikira ngati kwenikweni mphira zachilengedwe, Komabe, thupi la munthu adzakhala matupi awo sagwirizana mphira, ngati mwana wanu amasewera ndi zidole za zinthu zimenezi chifuwa, zikande, etc., musasankhe zoseweretsa zoterozo.
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 mphira wopangidwa ndi wokwera kwambiri, umangosewera nyenyezi zitatu chifukwa zidole zomwe nthawi zambiri zimagwiritsa ntchito mphira wamtunduwu, zidzakhalanso ndi zosakaniza 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 kuumba kwa nthawi imodzi, palibe chifukwa cha vulcanization, elasticity yabwino, ndipo pakali pano ndizitsulo zazikulu zotsika mtengo zomwe zimagulitsidwa pamsika, zomwe zikutanthauza kuti izi ndizinthu zopangira zinthu 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, ndi poizoni wochepa kuposa PVC, ndipo kubwezeretsanso kumakhala kosavuta, mankhwala ambiri a ana adzagwiritsa ntchito nkhaniyi, zinthu zazikulu zapulasitiki mwina ndi magulu awa, makolo mu chisankho cha zidole za tsitsi ana amayang'ana bwino zakuthupi, pambuyo pa zonse, zoseweretsazi zimalumidwa m'kamwa tsiku ndi tsiku, 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.
