Ngokwezindlela ezahlukene zokusebenzisa, ama-antistatic agents angahlukaniswa ngezigaba ezimbili: izithasiselo zangaphakathi kanye ne-external...Funda kabanzi -
ISIVIKELI SE-POLYMER: ISINYATHELI SE-UV
Isakhiwo sama-molecule sama-UV absorbers ngokuvamile siqukethe ama-double bond ahlanganisiwe noma ama-aromatic rings, angamunca imisebe ye-ultraviolet yama-wavelength athile (ikakhulukazi i-UVA ne-UVB). Lapho imisebe ye-ultraviolet ikhanyisa ama-molecule amuncayo, ama-electron kuma-molecule aguquka esuka emhlabathini...Funda kabanzi -
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?
Incazelo yokulinganisa Impahla yokulinganisa yengubo ichazwa njengekhono lengubo lokugeleza ngemva kokusetshenziswa, ngaleyo ndlela kukhulisa ukususwa kwanoma yikuphi ukungalingani kwendawo okubangelwa inqubo yokufaka. Ngokukhethekile, ngemva kokusetshenziswa kwengubo, kuba nenqubo yokugeleza kanye...Funda kabanzi -
Yini ethinta ukuhlanzwa kwezingubo?
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 -
