Nylon(polyamide, PA) ndi pulasitiki wauinjiniya wokhala ndi makina abwino kwambiri opangira zinthu, pomwe PA6 ndi PA66 ndi mitundu yodziwika bwino ya polyamide.

Komabe, ili ndi malire pakukana kutentha kwambiri, kusakhazikika kwamtundu, ndipo imakonda kuyamwa chinyezi ndi hydrolysis.

Kutengera chitsanzo cha PA6, nkhaniyi ikuwunika momwe ingathandizire kukana kukalamba. Kafukufuku wofananira awonetsa kuti magwiridwe antchito a PA6 amatha kupitilizidwa kwambiri powonjezera ma antioxidants oyenera ndi zina zowonjezera. Pambuyo pakuyezetsa kwakutali kwa UV komanso kuyesa kukhazikika kwamafuta, kuphatikiza kotereku kwapereka chitetezo chabwino pamakina ndi mtundu wa nayiloni:

①Antioxidant 1098 + Antioxidant 626

②Antioxidant 245 + Antioxidant 626

③Antioxidant 1098 + Antioxidant 168

Kuti muwonjezere moyo wautumiki wa PA, nthawi zambiri pamafunika kuwonjezera zowonjezera zina. Mwachitsanzo, kuwonjezera HALS kuti kuwala kukhale bata,Mtengo wa LS770ndi imodzi mwa njira zotheka ndi zochepa zimakhudza makina katundu. Pakadali pano, kampani yathu imapereka zida zambiri za nylon stabilizer yotchedwaMtengo wa LS438, zomwe zimathandizira kusungunuka kwa ma polyamide, kumathandizira kutentha kwanthawi yayitali komanso kukhazikika kwazithunzi, komanso kusintha mtundu.

Kuti muwonjezere kuyera ndi kuphimba chikasu, TiO2, ultramarine blue, optical lightening agents, ndi zina zotero zawonjezedwa ku Polyamide. TheOptical Brightener KSNoperekedwa ndi kampani yathu ndi chisankho chapamwamba komanso chosagwira kutentha.

Kuphatikiza apo,carbodiimide anti-hydrolysis wothandiziraikhoza kuwonjezeredwa kuti ipititse patsogolo ntchito yake ya anti hydrolysis ndikupititsa patsogolo nthawi yake yopangira makutidwe ndi okosijeni polumikizana ndi zowonjezera zina.

Malingaliro omwe ali pamwambawa sapanga chitsogozo chilichonse chaukadaulo, ndipo magwiridwe antchito amayenera kutsimikiziridwa ndi machitidwe a ogwiritsa ntchito.
