Yihoo A333-phenol-free kunye ne-hydrolysissississis yokuthintela i-antioxidant

Xa abafowunelwa be-fehenoccal yemveli nge-nitrogen kunye negesi yeoksijini emoyeni, ivelisa i-quonene yesakhiwo. I-findone yesakhiwo sisizathu sengcambu ye-tyheng kwaye ibomvu.

I-phosphite antioxidant isetyenziswa ngokubanzi njengomntu onesibindi esiphezulu. Nangona kunjalo, ngokuphuculwa okuqhubekayo kokukhuselwa kwemigangatho ye-EU, iimfuno ze-phosphite antioxidant iphakamileyo kwaye iphezulu. I-phosphite Antioxidant kufuneka ibe nobuhlobo obungakumbi ngokuyisingqongileyo, ingeyiyo eyobunzi, engabinayo i-Hhenolic, i-Hodrolysis, kwaye ixhathise amaqondo obushushu aphezulu.

I-phosphite anexilicy antioxidant yenye yezona zinto zisebenzayo zePolymer zokuZinza kwi-1990s. Kule minyaka ilishumi, izakhiwo ezitsha zamanani ziyavela ngokungapheliyo, kodwa ngesakhiwo sabo sekhemikhali, sinokufumana ukuba imeko entsha ye-phosphite inomsesane we-phosperic spittic spitoral dipthoral dipholtite kunye ne-bisphenol phosterite phoster. Kuthetha ukuba itekhnoloji ye-phosphate ye-phosphate ye-Anesphate ye-Anesphate ye-Antioxidant kufuneka ijolise kwimiba emibini: indlela yokuphucula uzinzo lwendlela kunye nendlela yokuphucula uzinzo lwe-hydrolylyc.

Our non-phenolic antioxidant -AN333&AN340, does not contain phenolic structure, so it can effectively avoid the yellowing problem caused by quinone structure. Iqondo lobushushu lokulungisa lingaphezulu kwe-180 ℃, kwaye lisetyenzisiwe kwi-pu, i-PVC kunye nezinye iinkalo ngabathengi abaninzi ngaphakathi nangaphesheya.

Phakathi kwabo, i-A333 iye yangqineka isebenza ngokugqibeleleyo kwezinto ezigwenxa ze-Pu, ngokuchasana nokunganyangeki kwe-hydrolysis. Yeyona nto iphambili yeJohoku Hlulelele iikhemikhali ze-jookoku e-jopp333e.

Ngaphandle kwe-antiolxidas, siyanikezela nezinye ezongeziweyo ezisetyenziswa kwisicelo se-PU. Apha ngezantsi iimveliso zenzelwe ukhetho lwakho:
