Dej Raws Txhuas Txhuas Txhuas | Aluminium Pigment
Nqe lus piav qhia:
Aluminium Paste, yog ib qho tseem ceeb ntawm cov xim hlau. Nws cov khoom tseem ceeb yog snowflake aluminium particles thiab roj av kuab tshuaj nyob rau hauv daim ntawv ntawm muab tshuaj txhuam. Nws yog tom qab kev siv tshuab tshwj xeeb thiab kev kho deg, ua rau aluminium flake nto du thiab tiaj tus ntug zoo nkauj, zoo li qub, particle loj tis concentration, thiab zoo heev txuam nrog txheej txheej. Aluminium Paste tuaj yeem muab faib ua ob pawg: hom nplooj thiab hom tsis-nplooj. Thaum lub sij hawm kev sib tsoo, ib qho fatty acid yog hloov los ntawm lwm tus, uas ua rau Aluminium Paste muaj cov yam ntxwv sib txawv kiag li thiab cov tsos, thiab cov duab ntawm aluminium flakes yog snowflake, ntses nplai thiab nyiaj duas. Mas siv nyob rau hauv automotive txheej, tsis muaj zog yas coatings, hlau industrial coatings, marine coatings, tshav kub-resistant txheej, vov tsev txheej thiab thiaj li nyob. Nws kuj yog siv rau hauv cov xim yas, khoom siv kho vajtse thiab cov khoom siv hauv tsev, pleev xim rau maus taus, xim tsheb kauj vab thiab lwm yam.
Yam ntxwv:
Water Based Aluminium Pigment, tseem hu ua aqueous aluminium paste, tsim nrog kev tsim cov txheej txheej aqueous. Aluminium yog ib qho khoom siv zoo nkauj amphoteric hlau thiab yooj yim rau kev hnov mob nrog dej, kua qaub thiab alkali. Nws yuav tsum tau kho tshwj xeeb saum npoo thaum ntxiv rau hauv aqueous resin system. Ntawm kev ua lag luam cov txheej txheem ntawm aqueous aluminium paste tuaj yeem muab faib ua 4 pawg:
1 Ntxiv corrosion inhibitor; 2 Chromic acid los yog chromate passivation; 3 Silica txheej txheej txheem; 4 Inorganic thiab organic ob-coated lossis interpenetrating networks method (IPN). Cov txheej txheem no muaj qhov zoo thiab qhov tsis zoo sib txawv. Nrog rau kev xav tau ntau dua rau kev tiv thaiv ib puag ncig, ob txoj hauv kev kawg yuav raug siv ntau dua.
Daim ntawv thov:
Lub aqueous aluminium paste yog dav siv hauv aqueous automotive coatings, rooj tog thiab lwm yam xim zoo nkauj, tshuaj pleev ib ce, ntim khoom noj, tawv thiab ntaub, menyuam yaus cov khoom ua si, thiab lwm yam.

Daim ntawv qhia kev thov:
1.Foam slurry ob peb, inures tom qab, stirring maj mam thiab ntxiv cov aqueous coatings emulsion, muaj peev xwm ntxiv ib co dispersant kom tsis txhob pawg thiab particle los nag.
2.Tsis txhob do hauv kev kub ceev, nyob rau hauv rooj plaub lub siab shear quab yuam rhuav tshem cov txheej ntawm aluminium pigment; rotating ceev yuav tsum tswj nyob rau hauv 300-800 rpm.
3.Rau cov txiaj ntsig zoo, koj yuav tsum tau lim dej zoo dua.
4.Nyob rau hauv lub sij hawm ntev cia, txhuas muab tshuaj txhuam yuav tsim cov khoom. Koj tuaj yeem tsau nws nrog dej ntshiab lossis glycol ether ob peb feeb, do me ntsis thiab tom qab ntawd yuav tshwm sim.
5. Cia: Tsis txhob tshav ntuj ncaj qha; tom qab siv cov tshuaj txhuam hniav, muab lub nruas npog sai sai.
Nco tseg:
1. Thov ua kom paub tseeb tias tus qauv ua ntej txhua qhov kev siv ntawm txhuas nyiaj muab tshuaj txhuam.
2. Thaum dispersing aluminium-silver paste, siv cov txheej txheem ua ntej dispersing: xaiv cov kuab tshuaj uas tsim nyog ua ntej, ntxiv cov kuab tshuaj rau hauv aluminium-silver paste nrog qhov piv ntawm aluminium-silver paste rau hnyav li 1: 1-2, do. maj mam thiab sib npaug, thiab tom qab ntawd ncuav nws mus rau hauv cov khoom siv hauv paus npaj.
3. Tsis txhob siv cov khoom siv dispersing high-speed rau lub sijhawm ntev ntawm kev sib tov.
Cov lus qhia cia:
1. Cov tshuaj txhuam hniav nyiaj hniav kub yuav tsum khaws lub thawv ntim thiab qhov ntsuas kub yuav tsum khaws cia ntawm 15 ℃ ~ 35 ℃.
2. Tsis txhob raug tshav ntuj ncaj qha, los nag thiab kub heev.
3. Tom qab unsealing, yog tias muaj lwm yam nyiaj txhuas muab tshuaj txhuam yuav tsum tau muab kaw tam sim kom tsis txhob hnyav evaporation thiab oxidation tsis ua hauj lwm.
4. Lub sij hawm ntev cia ntawm aluminium silver paste tej zaum yuav hnyav volatility lossis lwm yam kuab paug, thov rov sim dua ua ntej siv kom tsis txhob poob.
Kev ntsuas kub ceev:
1. Thaum muaj hluav taws kub, thov siv tshuaj hmoov los yog cov xuab zeb qhuav tshwj xeeb los tua hluav taws, tsis txhob siv dej los tua hluav taws.
2. Yog tias cov tshuaj txhuam hniav nyiaj hniav kub nkag mus rau hauv lub qhov muag, thov yaug dej kom tsawg li 15 feeb thiab nrhiav kev kho mob.
