Ubwino ndi Kuipa kwa Zinthu Zoletsa Moto Zosapangidwa ndi Zachilengedwe

Kugwiritsa ntchito kwambiri zinthu zopangidwa ndi polima kwathandiza kuti makampani opanga zinthu zoletsa moto azikula mofulumira. Zinthu zoletsa moto ndi zinthu zofunika kwambiri m'gulu la zinthu zomwe zimagwiritsidwa ntchito masiku ano, zomwe zimaletsa moto, zimaletsa kufalikira kwake, komanso zimathandiza kwambiri pa ntchito yokonza moto komanso pa moyo watsiku ndi tsiku. Zinthu zomwe zimathandizidwa ndi zinthu zoletsa moto zimatha kupewa, kuchepetsa, kapena kuletsa kufalikira kwa moto zikakumana ndi zinthu zakunja, zomwe zimapangitsa kuti moto ukhale woopsa. Pali mitundu yambiri ya zinthu zoletsa moto, ndipo chilichonse chili ndi mbali ziwiri—zinthu zoletsa moto zilinso ndi zabwino ndi zoyipa zake. Pansipa pali kusanthula kwa ubwino ndi kuipa kwa zinthu zosiyanasiyana zoletsa moto zopanda chilengedwe.

Zoyipa za Zoletsa Moto Zosapangidwa:
Vuto lalikulu la zinthu zoletsa moto zopanda chilengedwe ndi kuchuluka kwa zinthu zomwe zimafunika (makamaka zoposa 50%) mu zinthu za polima, zomwe zimatha kusokoneza magwiridwe antchito a polima komanso mawonekedwe ake. Mayankho akuphatikizapo kukonza pamwamba pogwiritsa ntchito zinthu zolumikizira, kukonza tinthu tating'onoting'ono kwambiri, ndi nanotechnology, zomwe zimayimira njira yofunika kwambiri pakukula kwamtsogolo.

Ubwino wa Zoletsa Moto Zosapangidwa ndi Zinthu Zachilengedwe:

1. Aluminium Hydroxide (ATH): Imaphatikiza ntchito zoletsa moto, kuletsa utsi, ndi kudzaza zinthu kukhala chimodzi. Sichimayambitsa poizoni, sichiwononga, sichimawononga kwambiri, sichipanga mpweya woopsa pa kutentha kwambiri, ndi yotsika mtengo, ndipo imapezeka paliponse.
2. Magnesium Hydroxide (MTH): Imawola pakati pa 340–490°C, imapereka kukhazikika kwabwino kwa kutentha komanso kuletsa moto komanso kuletsa utsi. Ndi yoyenera kwambiri pokonza mapulasitiki a polyolefin kutentha kwambiri.
3. Phosphorus Yofiira: Imaletsa utsi, imachepetsa poizoni, komanso imaletsa moto mwachangu. Komabe, phosphorous yofiira imatha kusungunuka mumlengalenga, imatha kuyaka yokha, ndipo pang'onopang'ono imatulutsa mpweya wa phosphine woopsa pakasungidwa kwa nthawi yayitali. Imagwirizana bwino ndi zinthu za polima, ndipo microencapsulation ndiye yankho lalikulu.
4. Ammonium Polyphosphate (APP): Ndi chinthu choletsa moto chomwe chimalowa mkati mwa thupi, chili ndi nayitrogeni ndi phosphorous yambiri, chimakhala ndi kutentha kwabwino, ndipo sichimasinthasintha kwenikweni. Chikhoza kusakanikirana ndi zinthu zina zoletsa moto, chimabalalika bwino, ndipo chimakhala ndi poizoni wochepa, zomwe zimapangitsa kuti chigwiritsidwe ntchito bwino. Komabe, pamene polymerization ya APP yachepa, imakhala yosungunuka pang'ono m'madzi. Kuphatikiza apo, APP imakhala ndi asidi pang'ono ndipo imatha kuyamwa chinyezi m'malo ozizira.
