Yintoni echaphazela ukungcoliswa kweengubo?
Ukucoca i-foam kukukwazi kwe-coating ukususa i-foam eveliswa ngexesha lenkqubo yokuvelisa kunye ne-coating. Ii-Defoamers luhlobo lwe-additive esetyenziselwa ukunciphisa i-foam eveliswa ngexesha lokuvelisa kunye/okanye ukusetyenziswa kwe-coating. Ngoko ke zeziphi izinto ezichaphazela ukucoca i-foam kwe-coating? 1. Umphezulu...Funda ngokugqithisileyo -
Iintlobo zee-UV absorbers
Ukwaziswa kwe-UV absorber I-Sunlight ine-ultraviolet eninzi enobungozi kwizinto ezinemibala. Ubude bayo obude bumalunga ne-290 ~ 460nm. Le mitha ye-ultraviolet enobungozi ibangela ukuba iimolekyuli zombala zibole kwaye ziphele ngenxa yeempendulo zokunciphisa i-oxidation yeekhemikhali. Ukusetyenziswa kwe-ultraviolet abs...Funda ngokugqithisileyo -
Ugquma i-antioxidant
Intshayelelo Ii-antioxidants (okanye iziqinisi zobushushu) zizongezo ezisetyenziselwa ukuthintela okanye ukulibazisa ukonakala kwee-polymers ngenxa ye-oksijini okanye i-ozone emoyeni. Zezona zongezo zisetyenziswa kakhulu kwizixhobo ze-polymer. Iingubo ziya kubola emva kokuba zibhakiwe kubushushu obuphezulu ...Funda ngokugqithisileyo -
I-surfactant yokucoca ulusu i-APG (i-Alkyl Polyglycoside)
