Pigment tuaj qhov twg?

Peb txhua tus tau siv los ua lub ntiaj teb ua kom muaj xim zoo nkauj. Nws yog ib qho nyuaj rau xav txog yam uas nws yuav cuam tshuam rau lub ntiaj teb kev hnov ​​​​qab yog tias peb nyob ib puag ncig ntawm cov xim dub thiab dawb. Peb pab tsis tau tab sis xav tsis thoob, ntxiv rau cov xim ntuj, cov pigments nthuav tawm los ntawm cov ntaub ntawv tuaj qhov twg?

Pigments yog cov xim uas tsis muaj kuab lom hauv cov kuab tshuaj thiab tuaj yeem muab faib ua cov xim tsis muaj organic thiab cov xim organic. Ntawm lawv, cov organic pigments yog cov xim organic sib txuas, uas tuaj yeem muab faib ua hom ntuj thiab hluavtaws. Qhov zoo ntawm cov organic pigments yog siab tinting zog, ci xim, tiav xim spectrum, thiab tsawg toxicity. Qhov tsis zoo yog tias cov khoom siv lub teeb ua haujlwm, kub ua haujlwm, huab cua tsis kam, hnyav tsis kam, thiab lub zog zais tsis zoo li cov xim tsis muaj zog.

Ntuj pigments yog muab rho tawm los ntawm cov zaub mov los yog cov nroj tsuag. Ancient murals yog cov khoom ntawm ntuj pigments. Cov neeg sawv cev tshaj plaws yog cov duab kos duab zoo nkauj hauv Mogao Grottoes hauv Dunhuang.

Synthetic pigments feem ntau yog siv hauv kev lag luam niaj hnub no. Lawv tau tsim nyob rau hauv 1856 los ntawm 18-xyoo-laus William Henry Perkin (WHJr. William Henry Perkin, Jr), uas yog ib tug tub ntxhais kawm ntawm Royal College of Chemistry hauv UK thaum lub sijhawm. Thaum sim ua ke quinine los ntawm kev siv tshuaj lom neeg siv thee tar, nws yuam kev rho tawm cov xim ntshav hauv kev sim thiab tsim aniline ntshav los ntawm potassium dichromate. Qhov no yog thawj zaug hauv keeb kwm uas tau tshawb pom cov khoom tsim tawm cov organic pigment, thiab nws tau qhib lub prelude rau ntau txoj hauv kev ntawm kev tsim cov xim loj los ntawm cov pa roj carbon purification.

Yunfu Hongzhi Cov Khoom Tshiab Co., Ltd. cov khoom precipitated barium sulfate kuj siv tau rau hauv cov xim:

1. Ntawm cov organic pigments, phthalocyanine xiav thiab phthalocyanine ntsuab muaj cov txiaj ntsig zoo tshaj plaws. Ntxiv precipitated barium sulfate nrog inorganic nto kev kho mob yuav txhim kho dispersibility, tswj cov khoom xim tsim, thiab correspondingly txhim kho cov khoom gloss thiab brightness.

2. Nws pab nrog kev sib tsoo (dispersion), tuaj yeem txo lub sij hawm sib tsoo, ua kom cov pigments sib npaug ntau dua, tuaj yeem txhim kho cov xim xim kev loj hlob (pigment extender), thiab tseem tuaj yeem siv los ua cov xim pleev xim.

3. Nws muaj cov nyhuv stabilizing rau ob qho tib si inorganic thiab organic pigments los tiv thaiv flocculation los yog ntab xim. Nano-precipitated barium sulfate hais tuaj yeem adsorbed nyob ib ncig ntawm cov xim pigment, ua rau muaj kev cuam tshuam tsis zoo los yog them rov qab kom ruaj khov ntawm cov xim.
