Lub ntsiab yog vim li cas rau kev lim ntshav hauv plawv
Peb yog ib lub tuam txhab luam ntawv loj hauv Shenzhen Tuam Tshoj. Peb muaj cov phau ntawv luam tawm, phau ntawv xov xwm luam ntawv, phau ntawv luam ntawv, phau ntawv nyuaj, phau ntawv luam tawm, phau ntawv luam tawm, phau ntawv luam tawm, lub thawv ntim, daim qhia ntawv, txhua yam ntawm PVC, cov ntawv luam tawm, ntawv sau cia, hom tshwj xeeb ntawv xim luam tawm khoom, kev ua si cardand li ntawd.

Tus lej khej yog ncaj qha ntsig txog lub agglomeration ntawm tus cwj pwm, uas tuaj yeem ua rau tus ntiv nplhaib thiab vitrification ntawm cov ntawv luam tawm lub cuav. Cov nqi ntawm pH los yog siv cov khoom pheej yig hauv inorganic tuaj yeem muab tus cwj mem rov los rau cov ntawv luam tawm thawj, uas tuaj yeem txhim kho cov dej ntws thiab dej ntxuav, thiab txo cov npuas dej los yog cov khoom ua kom yuag. Hauv qhov no, tus sau kuj tshuaj xyuas cov laj thawj nram qab no los ntawm cov xwm txheej saum toj no.
1. Ntau dispersion.
2. Cov cwj mem kua roj hmab yog muab ntxais rau hauv dej vim qhov tsis zoo, ua rau muaj dej ntws.
3. Cov pigment lossis muab phom hauv tus cwj mem kua xuav tsis ua rau lub thev nchuav los ntawm alkaline binder thiab neutralized, thiab chemically reacts mus noog.
4. Dia thiab ntawv yuav sib xyaw nrog plua plav lossis cov ntaub qhwv ntaub.
5. Siv cov tshuaj hnyav. Raws li qee cov tshuaj muaj kuab amphoteric los yog cov kuab tshuaj tivthaiv sib xyaw ua ke ua ib qho kev loj zuj zus agglomerate.
6. Cov lej tawm ntawm tus lej ntawm tus lej siab dhau lawm, lub plhaub taum taub hau luv heev, thiab cov ntsiab lus ntawm cov xim phev heev, tshwj xeeb tshaj yog cov neeg muab khoom siv tsis ua rau alkali khi rau ua rau nws swell. Yog hais tias nws tau kho nrog ib qho kua qaub, nws raug txo kom mus rau hauv lub cev, thiab tom qab ntawd ces rov qab los nrog qhov hnyav.
7. Ua kom tsis muaj teeb meem evaporation tsis txaus rau hauv lub cev. Hauv particular, qhov piv ntawm qhov tseeb qhov hnyav rau lub co-solvent yog kauj, thiab tus neeg saib xyuas kev tsis tuaj yeem thiab cov neeg tsis tuaj yeem tso tawm (exothermic) los yog volatilize tsis txaus.
8. Thaum sib ntxiv ntawm ammonia coj los rau hauv cov kua carbon dioxide, nws thaiv cov nqi ntawm cov khoom, accelerates qhov oxidation, txhawb nqa ua ke ntawm oxygen molecules nyob rau hauv dej, thiab ntau qhov ntxiv kuj tseem raug rau cov gloss.
9. Tom qab tus number case yog nyob rau hauv cov huab cua, muaj oxide zaj duab xis tov rau tus number case, thiab tus number case yuav muaj precipitated particles los yog luv luv number case thiab tsis sib luag dispersion.
10. Resin muaj pes tsawg leeg, me me, tshwj xeeb tshaj yog acrylic cob, uas thaum lub monomer ntawm acrylic acid nce mus txog 30%.
11. Txuas lub cev ntim ntau dua, qaug, thiab tsis sib haum xeeb yuav ua rau muaj kev mob ploj.
12. Txawm hais tias tus lej ntawm tus cwj pwm thiab cov kev tiv thaiv ntawm tus cwj pwm ntawm cov kab mob yuav raug kov yeej tom qab ntxiv cov pa roj carbon dawb, ntau tshaj qhov ntxiv ua rau tus cwj pwm ntws ntws thiab cov duab ntawm cov ntawv luam tawm kom tau qis dua.
13. Pigments lossis fillers muaj qhov sib npaug ntawm qhov sib npaug, tab sis cov ciav hlau qhov sib npaug tsis sib npaug thiab tseem nyob hauv lub xeev flocculated.
14. Tus cwj mem tshwm los rau flocculate los yog gel thaum tom qab nkag mus rau cov kua tshuaj acidic.
