Mapaipi aValavu ya mpiraNdi zida zamtundu wamba, zomwe zimakondedwa ndi makasitomala ambiri pamakhalidwe abwino kwambiri komanso ndalama zambiri. Chifukwa chake, lero, tiyamba ndi gulu la pulasitiki la pulasitiki, ndipo aliyense adziwe za mapaipi apulasitiki.
Pakadali pano, pali mitundu yotsatirayi ya pulasitiki 6 yomwe imagwiritsidwa ntchito mu msika wogulitsa:
1. Ndiwopepuka kulemera, mwamphamvu kwambiri, kumakhala ndi luso lodziletsa kwambiri komanso kukhazikika kwamphamvu kwambiri, ndipo itha kugwiritsidwa ntchito pokwerera, yotchinga, mpweya wabwino, etc.
2. Pupe la Polythylene, chitoliro cha Alias. Malinga ndi kuchuluka kwa kachulukidwe, imatha kuphatikizidwanso m'matumba apamwamba polyethylene, sing'anga yopanda polyethylene chitoliro ndi ma cunity otsika polyethylene. Anthu ambiri ali ndi mphamvu kwambiri komanso kupenda kutentha kwambiri, ndipo angagwiritsidwe ntchito kwa masitima am'matawuni ndi mapaipi amadzi; Sipakatikati-kachulukidwe kamakhala ndi kuuma kwabwino komanso mphamvu, koma khalani ndi kusinthasintha kwakukulu komanso kukana; Anthu otsika otsika amasinthira, kutalika kwa mtunda wautali ali ndi maubwino enanso, ndipo kukhazikika kwake kwamphamvu, kugwiritsa ntchito magwiridwe antchito ambiri, ndipo kumatha kugwiritsidwa ntchito pamzambiri, ndi kulumikizana, etc.
3. Imakhala ndi kukumbukira kwambiri, kutetezedwa kwa chilengedwe, kuchuluka kwa mankhwala, kutentha kwapamwamba kwambiri, ndipo uzitha kugwiritsidwa ntchito popanga matope, mapaipi am'mimba, etc. Itha kugwiritsidwanso ntchito ngati mapaipi onyamula chakudya pazachipatala.
4. Ndiwopanda zoopsa, zopanda fungo komanso waukhondo kwambiri. Ndi kutentha kwambiri komanso kuwononga nyama, ndi zinthu zabwino komanso zozizira zamadzi. Amagwiritsidwa ntchito makamaka kwa madzi ozizira komanso otentha komanso njira zopangira ma drive, njira zotentha zamadzi, ndi makina owongolera mpweya ku nyumba zaboma ndi mafakitale.
5. Ili ndi mphamvu yayikulu, yolimba kwambiri yolimba, ndipo sikophweka kukhazikitsa komanso kosavuta kugwira ntchito. Nthawi yomweyo, mtengo wake ndi wokwera, m'mimba mwake muli yaying'ono, ndipo imasokonekera mosavuta ndi ma hydrocarbons ena a hydrocarbons ndi ma soboos okhazikika, kotero pali mawonekedwe ena a ntchito.
6. Acrylonile-butadiene-styrene chitoliro, mashes. Ili ndi kutentha kwambiri, kukana kwa kuchuluka kwa chipongwe, kukana, ndipo sikuti ndi zoopsa, zopanda mphamvu, zaukhondo komanso zoyera, koma sikuyenera kusachedwa kutentha ndipo sikoyenera malo omwe akuwala ndipo sioyenera malo owala ndi dzuwa. Kutsidya lina, nthawi zambiri limagwiritsidwa ntchito pochotsa zinyalala, kuthilira, ndi pansi modekha; Ku China, nthawi zambiri amagwiritsidwa ntchito ngati madzi a m'nyumba, mayendedwe a zinthu zachilengedwe, etc.
