Ukuhlukaniswa kanye namaphuzu okusetshenziswa kwama-ejenti okulinganisa ukumboza
Ama-elevator asetshenziswa ekumbozweni ngokuvamile ahlukaniswa ngama-solvents axubile, i-acrylic acid, i-silicone, ama-polymer e-fluorocarbon kanye ne-cellulose acetate. Ngenxa yezici zayo zokucindezeleka okuphansi kobuso, ama-elevator awakwazi nje ukusiza ukumbozwa ukuthi kulingane, kodwa futhi angabangela imiphumela emibi. Ngesikhathi sokusetshenziswa, ...Funda kabanzi -
Iyini imfanelo yokulinganisa yezingubo?

Ukusula ifoam yikhono lokusula ifoam elikhiqizwa ngesikhathi sokukhiqiza kanye nenqubo yokusula. Ama-defoam aluhlobo lwesengezo esisetshenziselwa ukunciphisa ifoam elikhiqizwa ngesikhathi sokukhiqiza kanye/noma ukusetshenziswa kwezimbozo. Ngakho-ke yiziphi izici ezithinta ukuhlanza ifoam kwezimbozo? 1. Ububanzi...Funda kabanzi -
Izinhlobo zezifutho ze-UV
Ukwethulwa kwesithambisi se-UV Ukukhanya kwelanga kuqukethe ukukhanya okuningi kwe-ultraviolet okulimaza izinto ezinombala. Ubude bayo obungu-290 ~ 460nm. Le misebe ye-ultraviolet eyingozi ibangela ukuthi ama-molecule ombala abole futhi anyamalale ngenxa yokusabela kokunciphisa ukushiswa kwe-oxidation ngamakhemikhali. Ukusetshenziswa kwe-ultraviolet abs...Funda kabanzi -
I-antioxidant yokugqoka
Isingeniso Ama-antioxidants (noma ama-heat stabilizers) ayizithasiselo ezisetshenziselwa ukuvimbela noma ukubambezela ukuwohloka kwama-polymer ngenxa ye-oxygen noma i-ozone emkhathini. Yizithasiselo ezisetshenziswa kakhulu ezintweni ze-polymer. Izembozo zizowohloka ngokushisa ngemva kokubhaka endaweni ephezulu ...Funda kabanzi -
I-surfactant yokuhlanza isikhumba i-APG (i-Alkyl Polyglycoside)
I-APG, efushanisiwe ne-Alkyl Polyglycoside, iyi-surfactant engeyona i-ionic. Kalula nje, ifana "nomlingo wokuhlanza" omlingo ongenza imikhiqizo yokuhlanza isebenze kahle kakhulu. Inkanyezi ekhulayo ezithakweni zokunakekelwa kwesikhumba. Kusukela emvelweni Izinto zokusetshenziswa ze-APG zonke zivela emvelweni. Ngokuyinhloko ...Funda kabanzi -
