Lus teb

Barium sulfate yog qhov tseem ceeb inorganic cov khoom siv raw tshuaj raw khoom los ntawm barite raw raw. Nws tsis tsuas yog muaj kev ua tau zoo kho qhov muag thiab tshuaj lom neeg ruaj khov, tab sis kuj tseem muaj cov yam ntxwv tshwj xeeb xws li ntim xws li ntim, quantum loj thiab interface. Yog li ntawd, nws yog dav siv rau hauv cov tsho tiv no, plastics, ntawv, roj hmab, number case thiab xim. Nanometer Barium sulfate muaj qhov zoo ntawm thaj chaw siab ntawm thaj chaw siab, kev ua haujlwm zoo, thiab lwm yam. HCMILLING (GUILIN Hongcheng) yog lub chaw tsim khoom tshaj lij ntawmnarsib tsoo zebMachine. Peb linarNtsug Cov Menyuamtuav txhuv Tshuab yuavz ua 80-3000 mesh cov hmoov txhuv. Cov hauv qab no yog kev qhia rau cov ntawv thov ntawm nano barium sulfate.

1. Kev lag luam yas - tom qab ua nrog narsib tsoo zeblub tshuab

Ntxiv nano barium sulfate tiav los ntawm barite sib tsoo zeb tshuab rau kom tau cov khoom siv nrog siab muaj zog thiab nruj tau ntau dua thiab ntau dua xim. Piv txwv li, Barium sulfate tuaj yeem ntxiv rau polyethylene (PE), polypropylene (PP), polytetrorafluoroethylene (PTFE) thiab lwm yam ntaub ntawv. Tshwj xeeb, cov cuab yeej siv tshuab ntawm barium sulfate tau txhim kho tom qab kev hloov kho nto.

Rau feem ntau polymer composites, nrog kev nce ntawm kev hloov kho, lub zog thiab tawv ntawm cov khoom siv sib xyaw nce ua ntej thiab tom qab ntawd txo qis. Qhov no yog vim tias ntau dhau ntawm kev hloov pauv yuav ua rau muaj ntau-txheej lub cev ua kom zoo nkauj, ua rau nws nyuaj ua si cov yam ntxwv zoo ntawm inorganic fillers; Ib qho me me ntawm kev hloov kho me me yuav nce interface qhov tsis xws luag ntawm nano barium sulfate thiab cov neeg ua haujlwm qis, ua rau muaj kev txo qis hauv cov composite.

Ntxiv rau cov nyiaj saum toj no ntawm cov kev hloov kho saum npoo av muaj qhov cuam tshuam zoo ntawm cov khoom siv tshuab ntawm cov tshuab sib xyaw, tus nqi ntawm barium sulfate tseem yog qhov tseem ceeb tshaj plaws. Qhov no yog vim muaj lub zog ntawm nano barium sulfate loj heev, uas tuaj yeem ua lub luag haujlwm thaum ntxiv, yog li ua tau cov nyhuv muaj zog. Txawm li cas los xij, thaum cov ntsiab lus ntawm nano barium sulfate yog siab dhau (ntau dua 4%), vim hais tias ntawm nws agglomere nce, uas ua rau cov composite ntau dua rau pob txha lov, yog li ua lub cov khoom siv neeg kho tshuab ntawm cov composite zuj zus. Yog li ntawd, qhov kev sib ntxiv ntawm barium sulfate yuav tsum yog nyob hauv nws cov khoom tsim nyog cov khoom siv.

2. Txheej kev lag luam - tom qab ua nrognarsib tsoo zeblub tshuab

Raws li ib hom pigment, barium sulfate tau siv dav hlau ua kom zoo dua, cov dej kub tsis kam, cov kev ua kom nruj thiab cuam tshuam ntawm cov txheej txheej. Ib qho ntxiv, vim hais tias ntawm nws cov roj nqus roj qis thiab ua tiav tau hauv cov txheej txheej hauv dej, cov peev txheej, cov roj ntsha theem qis los txo tus nqi ntawm cov txheej txheem. Nws tuaj yeem hloov 10% ~ 25% ntawm titanium dioxide hauv cov txheej txheej dej. Cov txiaj ntsig qhia tau tias txoj kev tawv dawb tau txhim kho thiab lub zog nkaum lub zog tsis raug txo.

Cov yam ntxwv ntawm superfine barium barium sulfate rau txheej txheej yog: 1) zoo heev zoo particle loj thiab nqaim particle loj faib; 2) Nws yog pob tshab thaum dispersed nyob rau hauv resin daws; 3) Qhov tsis txaus ntseeg hauv txheej txheej hauv txheej. 4) Nws tuaj yeem siv los ua Dispersing tus neeg sawv cev ua ke nrog cov kab mob organic; 5) Nws tuaj yeem txhim kho cov khoom siv lub cev.

3. Daim ntawv kev lag luam - tom qab ua los ntawm narNtsug Cov Menyuamtuav txhuv lub tshuab

Barium sulfate feem ntau siv hauv kev lag luam papermaking vim tias nws lub cev zoo thiab tshuaj ruaj khov, loj dawb, thiab nqus ntawm cov teeb meem zoo nkauj.

Piv txwv, cov ntawv carbon yog ib qho kev kawm thiab khoom siv hauv chaw haujlwm, tab sis nws cov nplaim hluav taws xob yooj yim yuav tsum muaj cov roj nqus cov txiaj ntsig, uas tuaj yeem txhim kho lub hauv kev nqus cov ntawv; Lub particle loj yog me me thiab hnav khaub ncaws me, uas tuaj yeem ua rau cov ntawv ntau thiab ua rau muaj qis hnav lub tshuab.

4. Kev lag luam fiber ntau - tom qab ua los ntawm narNtsug Cov Menyuamtuav txhuv lub tshuab

Muaj fiber ntau, tseem hu ua "paj rwb", yog ib yam li kev nqus khoom zoo nkauj, xws li dej noo, thiab ua kom yooj yim. Nano barium sulfate muaj cov nyhuv zoo. Nano barium barium sulfate / regenerated cellulose muab los ntawm ob xws li cov khoom siv raw yog lub hom phiaj tshiab, uas tuaj yeem tswj hwm cov yam ntxwv ntawm txhua feem. Ntxiv mus, dhau ntawm "lub synergy" ntawm lawv, nws tuaj yeem ua rau cov tsis muaj tseeb ntawm cov khoom tshiab thiab qhia cov khoom tshiab ntawm cov khoom siv sib xyaw.
