Ntchito 5 Zotchuka za Polyethylene
Polyethylene - Polima Yosiyanasiyana M'mafakitale Angapo
Polyethylene, polima wosunthika, amapeza ntchito zambiri m'mafakitale osiyanasiyana chifukwa chotsika mtengo, kulimba, komanso kukana mankhwala ndi chinyezi. Nazi zinthu zisanu zomwe zimagwiritsidwa ntchito kwambiri ndi polyethylene:
1. Kunyamula
Polyethylene imagwiritsidwa ntchito kwambiri mumakampani opanga ma CD. Imagwiritsidwa ntchito popanga matumba apulasitiki, kukulunga pang'ono, kuphimba polyethylene ndi filimu yotambasula. Matumba a polyethylene amagwiritsidwa ntchito kwambiri pogula zakudya, kusungira chakudya, komanso kutaya zinyalala. Kukulunga pang'ono kumagwiritsidwa ntchito pomanga zinthu monga ma CD, ma DVD, ndi mabokosi a mapulogalamu. Filimu yotambasula imagwiritsidwa ntchito kuteteza ndi kuteteza mapaleti a katundu panthawi yonyamula.
2. Mipope ndi Zopangira
Mapaipi a polyethylene amagwiritsidwa ntchito kwambiri pantchito yomanga popereka madzi ndi ngalande. Ndiopepuka, osinthasintha, komanso osagwirizana ndi dzimbiri, zomwe zimawapangitsa kukhala abwino kwa mapaipi apansi panthaka. Zopangira za polyethylene, monga zigongono ndi zolumikizira, zimagwiritsidwanso ntchito kwambiri kulumikiza ndi kuwongolera mapaipi.
3. Mafilimu a zaulimi
Mafilimu aulimi ndi imodzi mwa ntchito za polyethylene. Polyethylene imagwiritsidwa ntchito kwambiri paulimi popanga mafilimu. Mafilimu owonjezera kutentha opangidwa kuchokera ku polyethylene amagwiritsidwa ntchito popanga malo otetezedwa kuti zomera zikule, kuteteza mbewu ku nyengo yoipa. Mafilimu a mulch opangidwa kuchokera ku polyethylene amagwiritsidwa ntchito kupondereza kukula kwa udzu, kusunga chinyezi, ndikuwongolera kutentha kwa nthaka.
4. Zida Zagalimoto
Zomwe zimagwiritsidwa ntchito ndi polyethylene. Polyethylene imagwiritsidwa ntchito m'makampani opanga magalimoto pazinthu zosiyanasiyana. Amagwiritsidwa ntchito popanga matanki amafuta, ma bumpers, ndi zopangira mkati. Matanki amafuta a polyethylene ndi opepuka, osagwira ntchito, ndipo amalimbana bwino ndi mankhwala. Mabampu opangidwa kuchokera ku polyethylene amathandizira kuyamwa mphamvu pakagundana, kuteteza kapangidwe kagalimoto. Zida zopangira mkati, monga mapanelo a zitseko ndi zida za dashboard, zimapangidwanso kuchokera ku polyethylene chifukwa cha kulimba kwake komanso kosavuta kuumba.
5. Zipangizo Zamankhwala
Polyethylene imagwiritsidwa ntchito kwambiri m'makampani azachipatala popanga zida zosiyanasiyana. Amagwiritsidwa ntchito popanga ma syringe, ma catheter, olowa m'malo olumikizirana mafupa, ndi manja opangira. Zida zamankhwala za polyethylene ndi biocompatible, kutanthauza kuti zimaloledwa bwino ndi thupi la munthu. Komanso ndi sterilzable, kuwapanga kukhala oyenera kugwiritsidwa ntchito popanga opaleshoni.
Izi ndi zitsanzo zochepa chabe za ntchito zambiri za polyethylene. Kusinthasintha kwake komanso zinthu zabwino kumapangitsa kuti ikhale yofunika kwambiri m'mafakitale ambiri, zomwe zimathandizira pa moyo wathu watsiku ndi tsiku m'njira zosiyanasiyana.
