Chifukwa chiyani aliyense amasankha PE udzu mphasa?Kodi mawonekedwe a nsalu ya polyethylene ndi chiyani?

Polyethylene ndi thermoplastic resin yopangidwa ndi polymerization ya ethylene.Zopanda fungo, zopanda poizoni, phula ngati chogwirira, kukana kutentha pang'ono, kukhazikika kwamankhwala, komanso kukana ma asidi ambiri ndi alkali.

Akayatsa kandulo, munthu amatha kuwona chodabwitsa: Kandulo ikayaka, imagwetsa mafuta a makandulo ndikudontha.Mu mapulasitiki, palinso "makandulo" oterowo.Maonekedwe ake amaoneka ngati kandulo, ndipo amamva mafuta akagwidwa ndi dzanja.Akayatsidwa ndi moto, “mafuta a kandulo” amatsikira limodzi ndi limodzi.Pulasitiki yamtunduwu, yotchedwa polyethylene, yomwe imatchedwanso "pulasitiki yamafuta a makandulo," nthawi zambiri imatchedwa "PE" code, ndipo chidule cha malonda a mankhwalawa ndi "pulasitiki ya ethylene."Polyethylene utomoni amapangidwa ndi polymerization wa ethylene.

Pali maubwino ambiri a nsalu yotchinga: 1. Kupewa kukula kwa udzu pansi.Kuphimba pansi kungathandize kuti dzuwa lisawalire pansi, pamene chotchinga cha udzu pachokha chimakhala champhamvu kwambiri ndipo chingalepheretse kukula kwa namsongole.2. Limbitsani ngalande pamwamba.Ndi mawonekedwe akeake, nsalu yotchinga imatha kuchotsa bwino madzi pansi, kusunga kufalikira kwa nthaka, ndikuthandizira kukula kwa mizu ya zomera.3. Chotchinga chabwino kwambiri cha udzu chikhoza Kuletsa kukula kwa mizu ndikusintha bwino mbewu.4. Kulima bwino ndi kusamalira zomera.Ngakhale kuyala mphasa yoletsa udzu, imatha kuwongolera bwino m'mphepete mwa nthaka, kupangitsa nthaka kukhala yopumira bwino komanso yabwino kumera.
