Lub luag haujlwm ntawm titanium dioxide hauv cov khoom siv roj hmab

1, Cov Haujlwm Tseem Ceeb
Kev Pleev Xim thiab Kev Ua Kom Dawb
Muab cov khoom siv roj hmab nrog cov xim dawb huv lossis cov xim ci ntsa iab, txhim kho qhov zoo nkauj ntawm qhov muag, thiab ua kom cov khoom zoo dua.
Tiv thaiv UV thiab tiv thaiv kev laus
Nqus cov teeb ci ultraviolet, ncua cov roj hmab daj, tawg, thiab kev ua haujlwm tsis zoo los ntawm lub teeb, thiab ntev nws lub neej kev pabcuam.
Cov Lus Qhia: Ntxiv rutile titanium dioxide rau hauv lub log tsheb tuaj yeem ua rau lawv tsis kam rau ozone thiab ultraviolet hluav taws xob.
Kev txhawb zog thiab kev sau
Txhim kho lub zog kho tshuab (xws li lub zog tensile thiab hnav tsis kam) ntawm cov khoom roj hmab, thiab siv lawv ua cov khoom siv ua haujlwm kom txo cov nqi tsim khoom.
2, Cov cheeb tsam thov sib cais
Cov log tsheb
Feem ntau yog hom rutile, sib xyaw nrog hom rutile (xws li qib R-350) los txhim kho kev tiv thaiv huab cua thiab tiv thaiv kev laus ntawm lub log tsheb los ntawm kev tawg ultraviolet.
Cov khoom siv niaj hnub thiab cov khoom lag luam
Khau/Hnab looj tes: Cov titanium dioxide ntse ua rau dawb thiab tiv taus hnub;
Cov khoom siv kis las/pem teb roj hmab: ua kom qhov chaw zoo nkauj dua thiab tiv taus kev hnav.
3. Tus yuam sij rau kev ua kom zoo dua qub
Kev xaiv hom siv lead ua
Hom titanium ntse: hom thoob ntiaj teb, tus nqi qis, siv rau cov khoom xim sib dua;
Hom Rutile: Hauv cov cheeb tsam uas muaj kev xav tau siab rau huab cua (xws li cov log tsheb sab), nws muaj kev tiv thaiv zoo heev rau kev daj.
Kev siv tshuab kho qhov chaw
Kev kho mob passivation ntawm silicon/aluminium txheej (xws li titanium dioxide R-350) tuaj yeem txo qhov kev cuam tshuam nrog cov roj hmab ntxiv thiab zam kev daj.
Kev koom tes ua qauv
Sib xyaw nrog cov pa roj carbon dub thiab cov neeg sawv cev tiv thaiv kev laus kom sib npaug tus nqi thiab kev hnav tsis kam;
Kev tswj qhov loj ntawm cov khoom me me (cov khoom me me) ua kom muaj kev sib kis zoo ib yam thiab tswj tau qhov elasticity ntawm roj hmab.
4. Kev ceev faj
Ntxiv tus nqi: Ntau dhau yuav cuam tshuam rau kev ua haujlwm ntawm cov roj hmab thiab yuav tsum tau hloov kho raws li cov khoom xav tau;
Kev Khaws Cia: Yuav tsum muaj ib puag ncig qhuav kom tiv thaiv kev nqus dej noo thiab kev sib sau ua ke;
Kev phooj ywg ib puag ncig: Ua tau raws li cov qauv tsis muaj tshuaj lom thiab tsim nyog rau cov khoom siv sib cuag xws li hnab looj tes.
Lus Cim: Titanium dioxide ua lub luag haujlwm ob qho tib si ua cov xim thiab cov khoom siv ua kom zoo hauv roj hmab, nrog nws cov ntsuas refractive siab (hom rutile ≈ 2.71) thiab kev ruaj khov tshuaj lom neeg yog lub hauv paus ntawm kev ua tau zoo.
