Hlau oxide pigments: tus yam ntxwv, daim ntawv thov

Manufacturers yuav tsum lossi txhim kho lub competitiveness ntawm lawv cov khoom vim hais tias ntawm qhov tam sim no saturation ntawm lub lag luam nrog mas thiab Lavxias teb sab ntaub ntawv. Yog li ntawd, ib txhij nrog lub zoo zog rau cov khoom thiab cov hniav uas yuav tsum tau yuam.

txhais

Hlau oxide pigments yog inorganic hom ntaub ntawv muaj li ntawm oxides thiab oxide hydrates ntawm ntau ntau ntau valency. Los ntawm cov qauv ntawm cov muab lawv muab faib ua tej yam ntuj tso thiab hluavtaws. Piv nrog rau lub ntuj tom kawg yog siv ntau heev. Nws txoj kev txaus cai no theem siab cov ntsiab ntawm coloring cov neeg ua hauj nyob rau hauv pigments xws li hluavtaws thiab tus nqi qis. Hlau oxides muaj loj heev ntau yam ntawm cov xim los ntawm dub mus xiav-ntsuab thiab daj tones.

Hlau oxide pigments: yam ntxwv

Ntawm cov thaj chaw ntawm pigments nws muaj nqis ntsoov teev hauv qab no:

• Kis tus nqi qhia qhov nqi them rau lub dav hlau ntawm kev sib sau. Lub sab hauv daim duab, cov tsawg yuav tsum siv tshuaj.
• Dispersity. Nrog zuj zus lawm fineness nce coloring muaj peev xwm.
• Siv - yog tus muaj peev xwm mus rau cov hloov lawv cev nqaij daim tawv thaum tov nrog rau lwm cov tshuaj ib tug tej yam saturation. Nws qhia txog cov kev siv raws li ib tug feem pua ntawm cov txheej txheem outputted los ntawm lub chaw tsim tshuaj paus.
• Lightfastness yog ib tug tsis kam rau photochemical nyhuv.
• Constancy. Txawm li cas los ntawm cov neeg sab nrauv laus yuav tsum tsis txhob hloov cov kev siv.
• Thermal stability - muaj peev xwm kom tau khaws cia xim nyob rau hauv ib tug kws kub ntau.
• Lub xub ntiag ntawm dej-soluble additives.
• Lub acidity ntawm cov aqueous ncua kev kawm ntawv. Nws yuav tsum tsis pub tshaj tus zoo tus nqi ntawm pH = 7. Vim lub fact tias cov MAAs txawv alkaline cov tshuaj tiv thaiv nruab nrab, vim kev siv ntawm ib tug tsawg acidity sib tov yog kiag li sis tsuas kob.

qhob uas tseg tau

Rau cov dyeing ntawm qhob khoom rau ib ntev lub sij hawm siv hlau oxide pigments muaj ib tug uas tsis muaj tej qho lub hwj chim thiab coloring yus yam ntxwv. Lawv tsis cuam tshuam los ntawm alkalis, tej yam acids, ntsev, tshav ntuj. Vim lub pigments tau ua thiaj li ntau thaum nrag MAAs co khoom.

Lub khw hlau oxide pigments ntawm txawv teb chaws thiab Lavxias teb sab siv thiab ua. Yuav ua qhob Hawj txawm nyob rau manufacturing cheeb tsam yuav tsum tau muab tshuaj los ntawm 3 mus rau 15% los ntawm ceeb thawj. Nws yuav tsum tau borne nyob rau hauv lub siab hais tias tus pigments muaj ib tug ntau dua dispersibility nyob rau hauv kev sib piv nrog Portland MAAs, tiam sis yog tias ntau tshaj tus tsim ntau, muaj yuav ib tug ntse nce nyob rau hauv ib tug sib tov dej yuam, ua tom qab rau ib tug ntau yam pauv loj txos ntawm lub dag lub zog thaum pouring thiab muaj zog porosity.

Pigments: kev siv ntawm

Kev cov ntaub ntawv ntawm cov khoom muaj feem xyuam rau cov efficiency ntawm kev siv ntawm dyes. Nrog me kev faib ua feem ntawm xim nyob rau hauv lub loj kom tau tag xaus ntawm uas tsim nyog cov khoom uas muaj ib tug high nws tus nqi. Xim hloov xim xwb MAAs phau ntawv los ntawm qhob mix thoob plaws, vim li ntawd cov tib tooj ntawm quaj tawv heev stain xim sib tov nrog ib tug high school cov ntsiab lus ntawm MAAs tshaj qhov nyhav uas tsis muaj.

Ob los yog ntau tshaj pigments siv los tsim ntxoov MAAs, txawv tones ntawm ib tug neeg dyes. Daim ntawv thov ntawm lub neej coj hom xim yuav tsum tau nws ua ntej incorporated rau hauv cov ntaub ntawv uas txog thaum lub Desired ntxoov ntxoo. Nws yuav siv sij hawm ntau tshaj ib tug xim xim.

yooj yim dyes

Xim Daj hlau oxide muaj kuj mus weathering, lub teeb stability, thermal stability, zoo heev coloring yam ntxwv. Nws yog siv nyob rau hauv qhov siv thiab ua kev ua vaj tse khoom nrog sib txawv cov hom phiaj, vuas, plaster, vov tsev cov vuas, ntau hom ntawm primers. Czech thiab Suav neeg dyes muaj zoo xws li cov zog, lub tom kawg yog nyob rau hauv tus nqi qis yog hom twg. Tej pigments yog tsim nyob rau hauv lub hauv paus ntawm ochre, txawv granular ruaj khov muaj pes tsawg leeg.

Dub hlau oxide xim - yog ib tug pheej tshuaj uas tau pom nws daim ntawv thov nyob rau hauv qhov siv thiab ua cov dawb lias MAAs khoom, fillers, dyes. Tsiag ntawv ukryvochnoy qhuav zas hom thiab qhov tob ntawm laus cov yam ntxwv, thaum nws tsis ploj thiab tsis raug kub cawv, ib tug nce qib ntawm alkali. Tiav lawm cov khoom uas agate lasting laus.

Ua liab xim mas Czech thiab Ukrainian manufacturers raws li ib tug powdery inorganic compound. Siv lub hauv paus muab durability thiab xim saturation.

Dawb coloring khoom yog tsis soluble nyob rau hauv cov organic acids thiab dej, raws li zoo raws li uas tsis yog-tshuaj lom rau tib neeg. Pom tau hais nyob rau hauv feem ntau tus neeg mob nyob rau hauv lub hnab ntawm 25 kg.

Lub degree ntawm tsuas yog tshwm sim los ntawm

Nyob rau hauv lub tiav lawm cov khoom coloring muaj feem xyuam rau cov Hawj txawm xis mas. Grey laus muaj lub peev xwm los dim brightness, li ntawd, thaum ua hauj lwm nrog tus qauv Portland MAAs yog ib qhov nyuaj rau tau tiag tiag li xim. Qhov zoo tshaj plaws kev xaiv yog ib dawb maas, siv kuj mus tsim lub xiav thiab ntsuab hues.

Txhua yam ntawm cov ntaub ntawv uas muaj ib tug grey xim nqaij daim tawv. Txawv raug nroj tsuag los kuj ua MAAs ntawm ib hom, uas txawv. Tej kev txawv yog pom nyob rau pleev xim rau vaj tse, nyob rau hauv lub teeb khoom yog yus ib tug ntau dua rhiab heev piv nrog rau ua vaj tse, muaj ib tug maub hlau oxide pigments. Yog li, rau tib lub batch ntawm cov khoom los ntawm cov khoom no yuav tsum tau ua ntawv thov cov tib MAAs los ntawm tib lub chaw tsim tshuaj paus.

Nyob rau hauv zaum kawg ntxoov ntxoo ntawm lub teeb khoom kuj cuam tshuam lub suab nrov ntawm lub muab tub lim. Muaj yog tiag tiag feem ntau niaj hnub muaj pes tsawg leeg nyob rau hauv zus tau tej cov ib zaug xwb consignment. Muaj yog ib tug tseem ceeb yuav txo tau ntawm cov nyhuv ntawm cov xim dub thiab xiav qhob. Nyob rau hauv cov xim yog tsis ntau cuam tshuam los ntawm cov kev ceev ntawm cov khoom, tab sis cov neeg pluag sealing ntawm ntxeem tau qhob yog qhov tshwm sim rau tshwm sim ntawm efflorescence thaum lub sij hawm cia thiab siv. Lawv zoo li qub lawm cov tsos, lawv tsis muaj feem xyuam rau lub pigments, tab sis efflorescence ntau npaum li cas hnov rau dawb lias nto tshaj tej yam ntuj tso.

Nws piv

Nyob rau hauv kev npaj cov MAAs sib tov hueing neeg sawv cev ntau npaum yuav tsum raug xam tias yog, los ntawm qhov hnyav, li hlau oxide pigments nyob rau hauv pob zeb ua muaj ntau densities. Nws tseem ceeb heev rau hwm lub sib npaug zos lub sij hawm ntawm stirring, qhov no yuav pleev xim lub sib tov tusyees.

Coj mus rau ib tug kev hloov ntawm cov xim sib txawv curing tej yam kev mob. Tej zaum yuav tshwm sim ib tug txawv ntxoov ntxoo ntawm cov ceev ceev evaporation ntawm noo noo thiab hws rau lub dav hlau, muaj kuj yog zaum ntawm ib tug me ntsis kov. Yuav kom muab tau cov kev kawm tshwm sim yuav tsum tau ua raws li proportions rau pob zeb ua dej dilution thiab kub tsoom fwv. Muaj yog ib tug yam ntxwv qauv: koob muaj ib tug siab ncuav point. Me muaju ua kom nrov loj lub teeb scattering, vim uas cov xim zoo sib zog tshaj lub suab nrov ntawm lub tib lub pob zeb solidified thaum uas tsis muaj kub.

hom ntawm pigments

Hlau oxide pigments yuav tau muab faib mus rau hauv tsis muaj zog, tag nrho cov tseem ceeb heev concentration uas yog 25%, thiab conditionally muaj zog ib concentration ntawm 10%. Yog hais tias tsim nyog rau muab ib tug tej yam Hawj txawm ntau tshaj li 10% ntawm cov colorant ntaub ntawv los ntawm lub ntim, nws yog ntshaw kom siv ib tug me me kev faib ua feem ntawm muaj zog hom xim. Qhov no yog vim hais tias ib tug loj kev faib ua feem deteriorates lub dag lub zog zog vim ntau zog dej haum.

Yuav kom tsim tau ib pastel pob zeb ua cov khoom yooj yim rau nruab ib tug me me kev faib ua feem, yog li ntawd nws yuav muaj kuab siv rau tag nrho cov feem ntawm conditionally tsis muaj zog zas xim.

manufacturers

Ntawm cov loj manufacturers yog ua lub German, Czech thiab Suav factories. Nyob rau hauv cov nqe lus ntawm muaj nuj nqis rau cov nyiaj, tam sim no ntau txaus nyiam pigments nyob rau hauv Tuam Tshoj. Qhov tseem ntau cov Czech tau txais liab thiab xim av tones. Qhov zoo tshaj plaws thawj German colorants, tab sis vim lub high nqi ntawm lawv daim ntawv thov rau paving txheej unprofitable.

Hlau oxide pigments (ua nyob rau hauv Russia) muaj ib tug uas tsis muaj nqi thiab fee zog, li ntawd, lawv ua ib tug tsim nyog sib txeeb import.
