Hais txog cov kev pab thiab kev titanium dioxide granularity
Nov 17, 2015

Nkaum zog thiab titanium dioxide particle loj muaj ib txoj kev ncaj, feem ntau speaking, nyob rau hauv txheej uas muaj xim kub ntim concentration, loj loj particle ntawm titanium dioxide xim los yog siab dua ntawd nyob rau hauv uas tsis muaj xim ntim concentration ntawm txheej lawv, titanium dioxide xim particle me me hu ua hwj huam loj muab tsawg mintsis thiab.

Pom los ntawm cov optics, pigments thiaj yuav lub teeb thiab haum yuav ua tau kom dawb thaum thiab es, xim nyob rau hauv lub chav tseem pom lub teeb, yuav luag sib npaug zog no qhia tag nrho wavelengths ci pom, ces scattering loj loj, yog yuav nqus heev tsawg. Ua rau kom lub opacity, nkaum zog thiab tinting ua tau ntawm cov kev taw qhia lub ntsiab yog kev txhim kho scattering zog titanium dioxide, ces yuav tsum taug kom hauv nruab nrog ces absorptive ntawm tus titanium dioxide. Nce scattering zog titanium dioxide heev rau lub tsev txhais tau hais tias kom titanium dioxide particle particle me me thiab cov loj tis tuaj yuav tsum muaj ib tug zoo dispersion. Muaj peev xwm absorptive mas nyob ntawm impurities tshem tawm tau tsim ntau li ntau tau AUTHORIZED xim zoo nkauj thiab zoo purity rau ntawm titanium dioxide tiv thaiv kom tus sib haum.

Thib ob, cov tsis muaj transparency

Dab qhov opacity hais txog cov xim hais uas muaj peev xwm ua lub teeb tawg tau. Tiag, nws yuav npog qhov tib. Ntawm zam tsoos titanium dioxide, opacity nyob ntawm nws cov refractive index thiab lis loj tis, tiam sis essence qhov uas kho qhov muag index refractive sib txawv resulting dioxide titanium nrog cov surrounding nruab nrab.

Nyob rau ntau tshaj ib nrab wavelength kab kev los ntawm pom lub teeb, titanium dioxide particle me me finer tus lis qauv yog ntau du thiab ntau dua dispersion, opacity, mam ntau dua thiab ntau dua. Tiam sis yog muaj tej yam tsis pub tshaj. Thaum lub nruab nrab particle loj 0.2 microns, thiab opacity ntawm tus zog nplaum ntau tshaj plaws, loj tshaj; thaum lub nruab nrab particle loj tshaj ib nrab ntawm kev wavelength ci pom, yog vim cov transparency uas siv lead ua lub teeb kev tsis. Nws yuav pom tias hais loj me me li no zoo.
