Lero, ndipitiliza kukutengerani kuti mumvetsetse mayina ndi kugwiritsa ntchito zida zingapo zoyambira zamapulasitiki pa moyo watsiku ndi tsiku, ndikukuthandizani kusiyanitsa ndikugawa m'magulu atsiku ndi tsiku.
PVC: PVC ikhoza kukhala imodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri pulasitiki, kuchokera ku zitseko za pulasitiki ndi mazenera m'moyo watsiku ndi tsiku mpaka mipope yamadzi, ngalande, nsapato, kutchinjiriza chingwe, zidole, jekeseni wopangidwa ndi zinthu, matupi owala, mankhwala opangidwa ndi extruded ndi msonkhano wagalasi , ma CD. , makhadi a ngongole, ndi zina zotero, ali ndi zizindikiro pafupifupi kulikonse, ndipo PVC ndi imodzi mwa zipangizo zapulasitiki zotsika mtengo.Zimakhala zosinthika, zosavuta kuziyika, zimakhala ndi zovuta zosiyanasiyana zomwe mungasankhe, zimatha kutulutsidwa, jekeseni-kuponyedwa ndi kupangidwa ndi mphutsi, zikhoza kulimbikitsidwa ndi galasi fiber, zimatha kukhalabe ndi makhalidwe ake pa kutentha kochepa, zikhoza kusindikizidwa, kusinthidwanso, ndipo imakhala ndi kukana kwabwino Kukhetsa ndi kupukuta, kukana kwa dzuwa ndi madzi a m'nyanja, mafuta abwino komanso kukana mankhwala.
PU: PU ndi chinthu chonga khungu, chimatha kupuma komanso kutambasula, koma chimatha kuumbidwa mosiyanasiyana makulidwe.Makhalidwewa adagwiritsidwa ntchito poyamba m'mafakitale opangira opaleshoni yachipatala ndi pulasitiki, ndipo amagwiritsidwa ntchito ngati zipangizo zothandizira odwala m'zipatala.Ili ndi kufalikira kwabwino, kuthamanga kwa mpweya, kutha kwamphamvu kuchira, kusakanikirana kosavuta ndi zinthu zokongoletsera, kuyamwa mwamphamvu, kuyamwa mwamphamvu, kulimba kosinthika, kulimba kwambiri, kusazirala, kumata, sikukwiyitsa khungu, ndipo kumatha kuponyedwa.
PC: Monga zinthu zamakono, PC imagwiritsidwa ntchito muzinthuzi kutanthauzira chinthu ndi mawonekedwe ake.Mankhwalawa sagwiritsa ntchito matabwa, koma amapangidwa ndi zinthu zina zamakono zomwe zili zoyenera kwambiri pa ntchitoyi.PC ndi yolimba ngati ma polima ena, komabe opepuka kulemera, ndipo amatha kupereka mitundu yosiyanasiyana ndi zotsatira pambuyo pokonza.Monga membala wa banja laling'ono la thermoplastic, PC, monga zida zina zambiri zapulasitiki, zidapezeka mwangozi ndi General Electric koyambirira kwa 1950s.Nkhaniyi imadziwika ndi kumveka bwino kwambiri komanso kulimba kwambiri, ndipo nthawi zambiri imagwiritsidwa ntchito m'malo mwa galasi pamagwiritsidwe ntchito monga kuwonekera komanso kusalala.Itha kupereka kumveka bwino kwamtundu, njira zosavuta zopangira komanso kukana kwabwino kwambiri.Itha kupereka zowonekera bwino, zowoneka bwino komanso zowoneka bwino.Ngakhale kutentha kwambiri, kukhazikika kwake kumakhalanso kolimba kwambiri, kukana kutentha kwambiri mpaka 125C, kukana moto, Kuteteza kwa radiation kumakhala kolimba, kobwezerezedwanso komanso kopanda poizoni.
Zida za pulasitiki ndizosiyanasiyana, zotsika mtengo, ndipo zimabweretsa kumasuka kwa moyo wamunthu.Ndi chidziwitso choyambirira cha zida, mutha kusankha bwino zofunikira zatsiku ndi tsiku m'moyo wanu.
