Yiziphi izinto ezikhanyisa ukukhanya kwe-fluorescent kumapulasitiki?
Ipulasitiki isetshenziswa kabanzi ezimbonini ezahlukene ngenxa yokuguquguquka kwayo kanye nezindleko eziphansi. Kodwa-ke, inkinga evamile ngamapulasitiki ukuthi avame ukuphuzi noma ashintshe umbala ngokuhamba kwesikhathi ngenxa yokuchayeka ekukhanyeni nasekushiseni. Ukuze kuxazululwe le nkinga, abakhiqizi bavame ukufaka izithasiselo ezibizwa ngokuthi ama-optical brighteners ukuze...Funda kabanzi -
Ziyini izibani zokukhanyisa ezibonakalayo?
Ama-optical brighteners, aziwa nangokuthi ama-optical brighteners (ama-OBA), ayizinto ezisetshenziswa ukuthuthukisa ukubukeka kwezinto ngokwandisa ubumhlophe nokukhanya kwazo. Avame ukusetshenziswa ezimbonini ezahlukahlukene, okuhlanganisa izindwangu, iphepha, insipho kanye nepulasitiki. Kulesi sihloko, sizochaza...Funda kabanzi -
Uyini Umehluko Phakathi Kwama-Nucleating Agents Nama-Clarifying Agents?
Kumapulasitiki, izithasiselo zidlala indima ebalulekile ekuthuthukiseni nasekuguquleni izakhiwo zezinto. Ama-nucleating agents kanye nama-crinsing agents yizithasiselo ezimbili ezinjalo ezinezinhloso ezahlukene ekufinyeleleni imiphumela ethile. Nakuba zombili zisiza ekuthuthukiseni ukusebenza kwemikhiqizo yepulasitiki, kubalulekile...Funda kabanzi -
Uyini umehluko phakathi kwezithambisi ze-UV kanye nezithambisi zokukhanya?
Uma kuvikelwa izinto zokwakha kanye nemikhiqizo emiphumeleni eyingozi yokukhanya kwelanga, kunezithasiselo ezimbili ezivame ukusetshenziswa: izifutho ze-UV kanye neziqinisi zokukhanya. Nakuba zizwakala zifana, lezi zinto ezimbili empeleni zihlukile kakhulu endleleni ezisebenza ngayo kanye nezinga lokuvikela ezikunikezayo. Njengoba...Funda kabanzi -
Abahlaseli be-Acetaldehyde
I-Poly(ethylene terephthalate) (PET) iyinto yokupakisha evame ukusetshenziswa embonini yokudla neziphuzo; ngakho-ke, ukuzinza kwayo ekushiseni kuye kwafundwa ngabaphenyi abaningi.
