Barium sulfate yog ib qho tseem ceeb inorganic chemical raw khoom ua los ntawm barite raw ore.Nws tsis tsuas yog muaj kev ua tau zoo kho qhov muag thiab tshuaj lom neeg ruaj khov, tab sis kuj muaj cov yam ntxwv tshwj xeeb xws li ntim, quantum loj thiab cuam tshuam cuam tshuam.Yog li ntawd, nws yog dav siv nyob rau hauv coatings, yas, ntawv, roj hmab, number case thiab pigment thiab lwm yam teb.Nanometer barium sulfate muaj qhov zoo ntawm qhov chaw tshwj xeeb ntawm qhov chaw, kev ua haujlwm siab, zoo dispersion, thiab lwm yam. Nws tuaj yeem ua tau zoo heev thaum siv rau cov khoom sib xyaw.HCMilling (Guilin Hongcheng) yog cov chaw tsim khoom lag luam ntawmbaritesib tsoo zebtshuab.Pebbaritentsug rollerzeb tshuab tuaj yeem zom 80-3000 mesh barite hmoov.Hauv qab no yog ib qho kev taw qhia rau daim ntawv thov teb ntawm nano barium sulfate.
1. Kev lag luam yas - tom qab ua tiav nrog baritesib tsoo zebtshuab
Ntxiv nano barium sulfate ua tiav los ntawm barite sib tsoo zeb tshuab rau polymer kom tau cov ntaub ntawv sib xyaw nrog lub zog siab thiab tawv tau nyiam ntau thiab ntau dua.Piv txwv li, barium sulfate tuaj yeem muab ntxiv rau polyethylene (PE), polypropylene (PP), polylactic acid (PLA), polytetrafluoroethylene (PTFE) thiab lwm yam ntaub ntawv.Tshwj xeeb, cov khoom siv kho tshuab ntawm barium sulfate tau txhim kho zoo tom qab kev hloov kho saum npoo.
Rau feem ntau ntawm cov khoom sib xyaw polymer, nrog kev nce ntawm tus nqi ntawm kev hloov kho, lub zog thiab tawv ntawm cov ntaub ntawv sib xyaw nce ua ntej thiab tom qab ntawd txo qis.Qhov no yog vim qhov ntau ntawm kev hloov pauv yuav ua rau ntau txheej ntawm lub cev adsorption ntawm nano barium sulfate, ua rau muaj kev sib txuam loj hauv cov polymer, cuam tshuam rau cov khoom siv ntawm cov khoom sib xyaw, thiab ua rau nws nyuaj rau kev ua si cov yam ntxwv zoo heev. inorganic fillers;Ib qho me me ntawm kev hloov kho yuav ua rau muaj qhov cuam tshuam cuam tshuam ntawm nano barium sulfate thiab polymer, uas ua rau txo qis hauv cov khoom ntawm cov khoom sib xyaw.
Ntxiv rau qhov saum toj no tus nqi ntawm qhov kev hloov kho saum npoo muaj qhov cuam tshuam zoo rau cov khoom siv kho tshuab ntawm cov khoom sib xyaw, cov nyiaj barium sulfate kuj yog ib qho tseem ceeb.Qhov no yog vim lub zog ntawm nano barium sulfate yog qhov loj heev, uas tuaj yeem ua lub luag haujlwm hauv kev coj tus kheej thaum ntxiv rau cov khoom sib xyaw, yog li ua rau muaj zog ntxiv.Txawm li cas los xij, thaum cov ntsiab lus ntawm nano barium sulfate siab dhau (ntau tshaj 4%), vim tias nws cov agglomeration nyob rau hauv cov khoom sib xyaw thiab ntxiv cov inorganic hais, cov matrix defects nce, uas ua rau cov sib xyaw ua ke ntau dua, yog li ua rau cov khoom sib xyaw ua ke. mechanical zog ntawm composite phem.Yog li, qhov ntxiv ntawm barium sulfate yuav tsum nyob rau hauv nws cov khoom tsim nyog.
2. Txheej kev lag luam - tom qab ua tiav nrogbaritesib tsoo zebtshuab
Raws li ib yam ntawm cov xim, barium sulfate yog dav siv nyob rau hauv coatings thiab plays lub luag hauj lwm tseem ceeb nyob rau hauv kev txhim kho thickness, puas kuj, dej tsis kam, kub tsis kam, deg hardness thiab cuam tshuam tsis kam ntawm coatings.Tsis tas li ntawd, vim tias nws tsis muaj roj tsawg thiab muaj peev xwm ua kom muaj peev xwm ua tau zoo, nws tuaj yeem siv rau hauv cov dej-raws li txheej, primers, nruab nrab coatings thiab oily coatings kom txo tau cov nqi ntawm coatings.Nws tuaj yeem hloov 10% ~ 25% ntawm titanium dioxide hauv cov txheej txheem dej.Cov txiaj ntsig tau pom tias qhov dawb huv tau txhim kho thiab lub zog zais tsis txo qis.
Cov yam ntxwv ntawm superfine barium sulfate rau coatings yog: 1) zoo heev particle loj thiab nqaim particle loj faib;2) Nws yog pob tshab thaum dispersed hauv resin tov;3) Zoo dispersibility hauv txheej txheej cov ntaub ntawv;4) Nws tuaj yeem siv los ua tus neeg sawv cev dispersing ua ke nrog cov xim organic;5) Nws tuaj yeem txhim kho lub cev zoo.
3. Ntawv kev lag luam - tom qab ua tiav los ntawm baritentsug rollerzeb tshuab
Barium sulfate feem ntau siv rau hauv kev lag luam papermaking vim nws lub cev zoo thiab tshuaj lom neeg ruaj khov, hardness nruab nrab, loj whiteness, thiab nqus cov teeb meem rays.
Piv txwv li, cov ntawv carbon yog ib qho kev kawm thiab cov khoom siv hauv chaw ua haujlwm, tab sis nws qhov chaw yog qhov yooj yim rau decolor, yog li barium sulfate yuav tsum muaj cov roj nqus dej siab, uas tuaj yeem txhim kho tus cwj mem nqus ntawm daim ntawv;Cov particle loj yog me me thiab tsis sib xws, uas tuaj yeem ua rau daim ntawv tiaj tus thiab ua rau lub tshuab tsis zoo.
4. Tshuaj fiber ntau kev lag luam - tom qab ua tiav los ntawm baritentsug rollerzeb tshuab
Viscose fiber, tseem hu ua "artificial paj rwb", zoo ib yam li cov paj rwb fiber ntau nyob rau hauv cov xwm, xws li anti-static, zoo noo noo nqus, yooj yim dyeing, thiab yooj yim textile ua.Nano barium sulfate muaj cov nyhuv nano zoo.Lub nano barium sulfate / regenerated cellulose muab fiber ntau ua los ntawm ob yam khoom siv raw yog hom tshiab ntawm cov fiber ntau, uas tuaj yeem tuav cov khoom tshwj xeeb ntawm txhua yam.Ntxiv mus, los ntawm "kev sib koom ua ke" ntawm lawv, nws tuaj yeem ua rau qhov tsis txaus ntawm cov khoom siv ib leeg thiab qhia cov khoom tshiab ntawm cov khoom sib xyaw.
