Zida 7 zomwe zimagwiritsidwa ntchito popanga matumba apulasitiki

M'moyo wathu watsiku ndi tsiku, tidzakumana ndi matumba apulasitiki tsiku lililonse. Ndi gawo lofunikira komanso lofunikira pa moyo wathu. Komabe, pali abwenzi ochepa omwe amadziwa za zinthu zamatumba apulasitiki. Ndiye kodi mukudziwa kuti ndi zinthu ziti zomwe zimagwiritsidwa ntchito kwambiri pamatumba apulasitiki?

Zida zomwe zimagwiritsidwa ntchito kwambiri pamatumba oyikamo apulasitiki ndi awa:

1. PE pulasitiki phukusi thumba

Polyethylene (PE), yofupikitsidwa ngati PE, ndi mamolekyu apamwamba kwambiri opangidwa ndi polymerization ya ethylene. Imazindikiridwa ngati chakudya chabwino cholumikizirana padziko lapansi. Polyethylene imateteza chinyezi, imalimbana ndi okosijeni, imalimbana ndi asidi, imalimbana ndi alkali, yopanda poizoni, yosakoma, komanso yopanda fungo. Imakwaniritsa miyezo yaukhondo pakuyika chakudya ndipo imadziwika kuti "maluwa apulasitiki".

2. PO thumba pulasitiki phukusi

PO pulasitiki (polyolefin), yofupikitsidwa ngati PO, ndi polyolefin copolymer, polima yopangidwa kuchokera ku olefin monomers. Zowoneka bwino, zowoneka bwino, zopanda poizoni, zomwe nthawi zambiri zimapangidwa ndi matumba a PO, matumba a PO, makamaka matumba apulasitiki a PO.

3. PP pulasitiki ma CD thumba

Matumba apulasitiki a PP ndi matumba apulasitiki opangidwa ndi polypropylene. Nthawi zambiri amagwiritsa ntchito kusindikiza kwamitundu ndi njira zosindikizira za offset ndi mitundu yowala. Ndi mapulasitiki otambasulidwa a polypropylene ndipo ndi amtundu wa thermoplastic. Non-poizoni, zoipa, yosalala ndi mandala pamwamba.

4. Chikwama cha pulasitiki cha OPP

Matumba opaka pulasitiki a OPP amapangidwa ndi polypropylene ndi bidirectional polypropylene, yomwe imadziwika ndi kuyaka kosavuta, kusungunuka ndi kudontha, chikasu pamwamba ndi buluu pansi, utsi wochepa ukachoka pamoto, ndikupitilizabe kuyaka. Ili ndi mawonekedwe owonekera kwambiri, kulimba mtima, kusindikiza bwino, komanso kutsutsa mwamphamvu zachinyengo.

5. Chikwama cha pulasitiki cha PPE

Chikwama cha pulasitiki cha PPE ndi chinthu chomwe chimapangidwa pophatikiza PP ndi PE. Mankhwalawa ndi osagwirizana ndi fumbi, antibacterial, chinyezi, anti-oxidation, kutentha kwambiri, kukana kutentha, kukana mafuta, kusakhala ndi poizoni komanso kosanunkhiza, kuwonetseredwa kwakukulu, mphamvu zamakina, ndi anti-blasting High performance, amphamvu puncture ndi misozi kukana, etc.

6. thumba la pulasitiki la Eva

Matumba apulasitiki a EVA (matumba achisanu) amapangidwa makamaka ndi zinthu zokometsera za polyethylene ndi zida zofananira, zomwe zimakhala ndi 10% EVA zakuthupi. Kuwonekera bwino, chotchinga cha okosijeni, umboni wa chinyezi, kusindikiza kowala, thumba lowala la thumba, limatha kuwonetsa mawonekedwe a chinthucho, kukana kwa ozoni, kubweza kwamoto ndi zina.

7. PVC pulasitiki ma CD thumba

Zipangizo za PVC ndizozizira, zowoneka bwino, zowoneka bwino kwambiri, zokonda zachilengedwe komanso zopanda poizoni, zosawononga zachilengedwe (6P ilibe phthalates ndi miyezo ina), etc., komanso mphira wofewa komanso wolimba. Ndi yotetezeka komanso yaukhondo, yokhazikika, yokongola komanso yothandiza, yowoneka bwino komanso yosiyana siyana. Ndi yabwino kwambiri ntchito. Ambiri opanga zinthu zapamwamba nthawi zambiri amasankha matumba a PVC kuti anyamule, kuyika zinthu zawo mokongola, ndikukweza magiredi awo.

Zomwe zafotokozedwa pamwambapa ndi zina zomwe zimagwiritsidwa ntchito m'matumba apulasitiki. Posankha, mungasankhe zipangizo zoyenera kuti mupange matumba apulasitiki apulasitiki malinga ndi zosowa zanu zenizeni.
