Ukwahlulahlula kunye neendawo zokusetyenziswa kweearhente zokulinganisa ungqimba
Iiarhente zokulinganisa ezisetyenziswa kwiingubo zihlala zahlulwe zibe zii-solvents ezixutyiweyo, i-acrylic acid, i-silicone, ii-fluorocarbon polymers kunye ne-cellulose acetate. Ngenxa yeempawu zayo zoxinzelelo oluphantsi lomphezulu, iiarhente zokulinganisa azinakunceda kuphela ukuba i-coating ifikelele kwinqanaba, kodwa zinokubangela neziphumo ebezingalindelekanga. Ngexesha lokusetyenziswa, ...Funda ngokugqithisileyo -
Yintoni ipropati yokulinganisa iingubo?
Inkcazo yokulinganisa Ipropati yokulinganisa yengubo ichazwa njengamandla engubo ukuba ihambe emva kokusetyenziswa, ngaloo ndlela isusa naluphi na ukungalingani komphezulu okubangelwa yinkqubo yokufaka. Ngokukodwa, emva kokuba ingubo isetyenzisiwe, kukho inkqubo yokuhamba...Funda ngokugqithisileyo -
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 -
