Yimiphi imisebenzi eyinhloko ye-titanium dioxide kumapayipi?

1, Imisebenzi Eyinhloko
Thuthukisa ukumelana nesimo sezulu kanye nokumelana nokuguga: i-titanium dioxide (TiO2) ingalibazisa ngempumelelo inqubo yokuguga kwamapayipi (njenge-PVC kanye namapayipi e-PE) endaweni engaphandle, ivimbele ukuphuzi, ukuqhekeka kanye nokushibilika kobuso, futhi yandise kakhulu impilo yesevisi ngokumunca ukukhanya kwe-ultraviolet nokuvimbela ukusabela kwe-photochemical. I-Rutile titanium dioxide inekhono eliqinile lokuvikela i-UV ngenxa yokwelashwa kokumboza (njenge-zirconia/alumina).
Thuthukisa ukumbozwa kanye nobumhlophe: Isici se-refractive index ephezulu sivumela i-titanium dioxide ukuthi isakaze ukukhanya okubonakalayo, imboze umbala oyisisekelo we-substrate yepayipi (njengombala ophuzi okhanyayo wesisekelo se-PVC), okwenza umkhiqizo ube mhlophe kakhulu, umbala ofanayo, kanye nokubukeka okukhanyayo. Imodeli yethoni yesigaba esiluhlaza okwesibhakabhaka ingathuthukisa ubumhlophe obubonakalayo.
Ukuthuthukisa ukusebenza kokucubungula kanye nokuqina: Ukumuncwa okuphansi kwamafutha (≤ 23g/100g) kanye namasu okwelapha ubuso obungokwemvelo (njengokufaka ukukhanya kwe-TR-36) kuthuthukisa ukuhlakazeka kwe-titanium dioxide ekuncibilikeni kwepulasitiki, kunciphisa ukusetshenziswa kwamandla okukhiqiza, futhi kugweme amaphutha afana nama-pores kanye nama-flow marks ebusweni bamapayipi.
2, Izidingo zesicelo esikhethekile
Ukuzivumelanisa nokumelana nesimo sezulu: Amapayipi angaphandle kumele asebenzise i-rutile titanium dioxide (njenge-SR-236, R-838), okumbozwa kwayo okungamelana nokuwohloka kwe-resin okubangelwa yi-UV catalysis; Uhlobo lwe-titanium olubukhali luthambekele ekusheshiseni ukuguga kwamapayipi ngenxa yokumelana nesimo sezulu okubi.
Ithoni yombala kanye nokulawulwa kwensimbi esindayo: I-titanium dioxide yesigaba esiluhlaza okwesibhakabhaka (njenge-R-248) ingamelana nombala ophuzi ongokwemvelo wamapayipi e-PVC futhi ithuthukise ubumsulwa bawo; Kufanele kuqashelwe okuqukethwe kwensimbi esindayo (njenge-chromium kanye ne-lead) ye-titanium dioxide emapayipini ahlobene namanzi ukuze kugwenywe ukungcolisa ikhwalithi yamanzi.
Ukuhambisana nokwengezwa: Amapayipi e-PVC aqukethe iziqinisi zikasawoti we-lead kufanele akhethwe ngamamodeli afanele ukuvimbela ukusabela okubi phakathi kwe-titanium dioxide kanye neziqinisi.
4, iziphakamiso zokusetshenziswa
Inani lokwengeza: ngokuvamile 3% -5% yesisindo sezinto ezibonakalayo, ezilungiswa ngokwezidingo zokumelana nesimo sezulu;
Ukuvikelwa kokusebenza: Kudingeka indawo yokugcina engangeni umswakama, futhi amagilavu ​​​​nezibuko zokuzivikela kufanele zigqokwe ngesikhathi sokusebenza.
Qaphela: Ukufuduka kwe-titanium dioxide ensimbi esindayo emapayipini ahlobene namanzi kufanele kuqinisekiswe ngokuqinile ukuqinisekisa ukuhambisana nezindinganiso zokuhlanzeka.
