1. Lub luag haujlwm ntawm titanium dioxide hauv cov txheej txheej
Cov coatings feem ntau yog tsim los ntawm plaub ntu: cov yeeb yaj kiab tsim cov tshuaj, cov xim, cov kuab tshuaj thiab cov tshuaj ntxiv.Cov pigments hauv txheej txheej muaj qee lub zog zais.Nws tuaj yeem tsis tsuas yog npog cov xim qub ntawm cov khoom coated, tab sis kuj muab cov xim ci ci.Paub txog qhov zoo nkauj ntawm cov teeb pom kev zoo thiab kev zoo nkauj.Nyob rau tib lub sijhawm, cov xim yog sib xyaw ua ke nrog tus neeg sawv cev kho thiab cov substrate, thiab kev sib xyaw ua ke, tuaj yeem txhim kho cov neeg kho tshuab lub zog thiab adhesion ntawm txheej zaj duab xis, tiv thaiv kev tawg lossis poob tawm, thiab tuaj yeem ua rau lub thickness ntawm txheej txheej, tiv thaiv. kev nkag mus ntawm ultraviolet rays los yog ya raws, thiab txhim kho lub txheej.Cov khoom tiv thaiv kev laus thiab ua haujlwm ntev ntawm cov yeeb yaj kiab txuas ntxiv lub neej kev pabcuam ntawm zaj duab xis thiab cov khoom tiv thaiv.
Nyob rau hauv cov xim, tus nqi ntawm cov xim dawb yog loj heev, thiab kev ua tau zoo ntawm cov txheej txheem rau cov xim dawb: ①Zoo whiteness;② Zoo sib tsoo thiab wettability;③ Cov huab cua tsis zoo;④ Muaj tshuaj lom neeg ruaj khov;⑤ Me me me me, zais lub zog thiab poob Siab xim lub zog, zoo opacity thiab gloss.
Titanium dioxide yog ib hom xim dawb uas tau siv dav hauv txheej txheej.Nws cov txiaj ntsig tso nyiaj ntau dua 70% ntawm cov xim tsis muaj zog, thiab nws cov khoom siv rau 95.5% ntawm tag nrho cov xim dawb.Tam sim no, kwv yees li 60% ntawm lub ntiaj teb titanium dioxide yog siv los tsim ntau yam txheej, tshwj xeeb tshaj yog rutile titanium dioxide, feem ntau yog siv los ntawm kev lag luam txheej.Cov xim ua los ntawm titanium dioxide muaj cov xim ci, lub zog zais siab, lub zog tinting muaj zog, tsawg npaum li cas, thiab ntau yam.Nws tiv thaiv kev ruaj ntseg ntawm qhov nruab nrab, thiab tuaj yeem txhim kho cov neeg kho tshuab lub zog thiab adhesion ntawm cov xim zaj duab xis, tiv thaiv cov kab nrib pleb, thiab tiv thaiv kab mob ultraviolet.Nws nkag mus nrog dej thiab ncua lub neej ntawm cov xim zaj duab xis.Cov xim sib txuam ntawm yuav luag txhua tus qauv hauv cov xim xim xim yog sib cais los ntawm titanium dioxide.
Cov txheej txheem sib txawv rau cov hom phiaj sib txawv muaj cov kev cai sib txawv rau titanium dioxide.Piv txwv li, hmoov txheej yuav tsum tau siv rutile titanium dioxide nrog zoo dispersibility.Anatase titanium dioxide muaj zog decoloring tsawg thiab muaj zog photochemical kev ua si.Thaum siv cov hmoov coatings, cov zaj duab xis txheej yog nquag yellowing.Lub rutile titanium dioxide tsim los ntawm txoj kev sulfuric acid muaj qhov zoo ntawm tus nqi nruab nrab, zoo dispersion, zoo nkaum hwj chim thiab xim txo hwj chim, thiab yog heev haum rau sab hauv tsev hmoov coatings.Ntxiv rau qhov zoo dispersibility, zais lub zog thiab xim txo lub zog, titanium dioxide rau cov hmoov txheej sab nraum zoov kuj xav tau huab cua zoo.Yog li ntawd, titanium hmoov rau sab nraum zoov hmoov txheej yog feem ntau rutile titanium dioxide tsim los ntawm chlorination.
2. Kev tshuaj xyuas qhov cuam tshuam ntawm qhov kev hloov pauv tseem ceeb ntawm titanium dioxide ntawm cov txheej txheej
1 dawb
Titanium dioxide yog siv los ua cov xim dawb rau txheej txheej.Nws cov xim dawb yog ib qho tseem ceeb heev thiab yog ib qho ntawm cov cim tseem ceeb uas yuav tsum tau ua los ntawm coatings.Qhov tsis zoo dawb ntawm titanium dioxide yuav cuam tshuam ncaj qha rau cov tsos ntawm txheej zaj duab xis.Lub ntsiab tseem ceeb cuam tshuam rau qhov dawb ntawm titanium dioxide yog hom thiab cov ntsiab lus ntawm kev puas tsuaj impurities, vim titanium dioxide yog rhiab heev rau impurities, tshwj xeeb tshaj yog rutile titanium dioxide.
Yog li ntawd, txawm tias ib qho me me ntawm impurities yuav muaj kev cuam tshuam loj rau cov xim dawb ntawm titanium dioxide.Qhov dawb ntawm titanium dioxide uas ua los ntawm cov txheej txheem chloride feem ntau zoo dua li cov txheej txheem sulfuric acid.Qhov no yog vim cov khoom siv raw titanium tetrachloride siv hauv kev tsim cov titanium dioxide los ntawm cov txheej txheem chloride tau distilled thiab purified, thiab nws cov ntsiab lus impurity tsawg dua, thaum cov txheej txheem sulfuric acid siv cov ntaub ntawv raw muaj impurity siab, uas tuaj yeem tsuas raug tshem tawm los ntawm kev ntxuav thiab tshuaj dawb.
2 lub zog zais
Lub zog zais yog thaj tsam ntawm cov khoom coated ib square centimeter.Thaum nws tag lawm, tib cheeb tsam yog pleev xim rau.Qhov ntau dua lub zog zais ntawm titanium dioxide siv, lub thinner lub txheej zaj duab xis yuav ua tau, thiab tsawg npaum li cas ntawm cov xim yuav tsum tau, Qhov me me ntawm cov titanium dioxide xav tau, yog tias lub zog zais ntawm titanium dioxide txo qis, thiaj li yuav tsum tau siv cov titanium dioxide. Ua tiav cov nyhuv npog zoo ib yam, qhov ntau ntawm titanium dioxide yuav tsum tau nce, tus nqi tsim khoom yuav nce, thiab qhov nce ntawm cov titanium dioxide yuav ua rau cov titanium dioxide nyob rau hauv txheej yog nyuaj rau disperse uniformly, thiab aggregation tshwm sim, uas yuav. kuj cuam tshuam cov nyhuv ntawm cov txheej txheem.
3 huab cua tsis kam
coatings yuav tsum muaj huab cua tsis kam ntawm titanium dioxide, tshwj xeeb tshaj yog rau sab nraum zoov txheej txheej, uas yuav tsum tau muaj huab cua tsis kam los yog ultra-high weather resistance.Siv cov titanium dioxide nrog cov huab cua tsis zoo, cov zaj duab xis txheej yuav muaj teeb meem xws li fading, discoloration, chalking, cracking, thiab tev.Cov qauv siv lead ua ntawm rutile titanium dioxide yog nruj dua li ntawm anatase titanium dioxide, thiab nws cov haujlwm photochemical tsawg.Yog li ntawd, huab cua tsis kam yog siab dua li ntawm anatase titanium dioxide.Yog li, titanium dioxide siv rau txheej txheej yog rutile titanium dioxide.Txoj hauv kev tseem ceeb los txhim kho huab cua tiv thaiv ntawm titanium dioxide yog ua kom tsis muaj kab mob hauv qhov chaw kho mob, uas yog, txhawm rau txheej ib lossis ntau txheej ntawm inorganic oxides lossis hydrated oxides rau saum npoo ntawm titanium dioxide hais.
4 kev tawg
Titanium dioxide yog ultra-fine hais nrog thaj tsam loj thiab lub zog siab.Nws yog ib qho yooj yim rau aggregate ntawm hais thiab yog ib qho nyuaj rau stably disperse nyob rau hauv coatings.Qhov tsis zoo ntawm cov titanium dioxide yuav cuam tshuam ncaj qha rau nws cov khoom siv kho qhov muag xws li txo cov xim, zais lub zog thiab gloss hauv cov txheej, thiab tseem cuam tshuam rau qhov ruaj khov, fluidity, leveling, coating durability, thiab corrosion kuj ntawm cov txheej.Daim ntawv thov cov khoom xws li hluav taws xob conductivity thiab conductivity kuj yuav cuam tshuam rau cov nqi ntawm cov coatings, vim hais tias lub zog siv ntawm kev sib tsoo thiab dispersion kev khiav hauj lwm yog siab, accounting rau feem ntau ntawm tag nrho cov zog siv ntawm txheej txheej manufacturing txheej txheem, thiab poob ntawm cov khoom yog loj. .
Qhov kev thov rau titanium dioxide tau nce xyoo no, tshwj xeeb tshaj yog rau cov titanium dioxide siv nyob rau hauv lithium-ion aviation kev lag luam, uas tseem yuav tsum tau cia siab rau imports.Raws li cov dej ntws qis ntawm titanium dioxide, cov txheej txheej tau cuam tshuam los ntawm ib puag ncig cua daj cua dub, thiab ntau lub lag luam me thiab nruab nrab tau raug kaw.Nyob rau hauv lub neej yav tom ntej, tus nqi ntawm titanium dioxide nyob rau hauv lub lag luam coatings kuj yuav txo.
