I-Rosin gum leguculwe nge-Fumaric acid (i-ejenti lesetjentiswa kakhulu yekulinganisa lene-esidi) yenta ncono kusimama kweliphepha nge-oxidation lenhle kakhulu kanye ne...Fundza kabanti -
I-maleic anhydride isetjentiswa njani embonini yetindvwangu?
Tintfo Letisitako Tetindvwangu.Intfo lehlanganisiwe yekutsambisa (lesekelwe ku-ester lendze ye-thiodisuccinic acid, lehlanganiswe kusuka ku-MA maleic anhydride kanye ne-stearyl alcohol) isetjentiselwa kutsambisa tindvwangu takotini, silika, kanye ne-polyester. I-MA iphindze isetjentiswe kwenta ema-ejenti emhlophe lakhanyako kanye netisakateli tedayi tekushicilela tindvwangu ...Fundza kabanti -
Yini umphumela we-maleic anhydride kumapulasitiki?
Tintfo letifaka emapulasitiki.I-dibutyl maleate lesuselwa ku-Maleic anhydride kanye ne-dioctyl maleate tipulasitiki letinhle kakhulu tangekhatsi temapulasitiki. I-Hexahydrophthalic anhydride kanye ne-diphenyl maleate (leyentiwe nge-MA Maleic anhydride) tintfo letisebenta ngendlela lesetulu tekukhicita emapulasitiki langaphandle.
