Abstract
The present invention provides a method for making anti-wearing white blackboard and its white blackboard product made up by using said invented method. It is mainly characterized by that the ceramic glaze and porcelain enamel are respectively sprayed on the surface of steel sheet, and prime coat and finish coat so made are separately passed through high-temp. firing treatment so as to obtain the surface of said white blackboard which not only can be written with oil pen as well as water pen, but also possesses high wear resistance, and can be used durably.
Description
The present invention relates to a kind of method of making wear-resistant white blackboard and reach the prepared wear-resistant white blackboard goods of method thus, say in detail, according to the prepared white blackboard of method of the present invention, compare with existing white blackboard, not only have preferable wear resistance and have preferable resistance to acid and surperficial wiping, so work-ing life is longer.
The manufacture method of Chang Yong white blackboard is on the whole for being coated with steel plate with the plastic cement baking vanish simply now, dries then and makes white blackboard, and the surface can be for a versicolor blank Writing-painting and absorption magnetite.
Yet the surface of above-mentioned existing mode manufacturing white blackboard wears no resistance usually, use for some time after, surperficial The book of Changes wiping etc. and be subjected to scratch, can't remedy, thus the surface again fully wiping and make whiteboard surface not pure white in only, leave various stained vestiges, lifetime.
The object of the present invention is to provide a kind of method of making wear-resistant white blackboard and by the white blackboard finished product of its method manufacturing, its method mainly is sprayed at surface of steel plate with the solution ceramics glaze, be divided into ground-coat enamel and the cover-coat enamel high-temperature firing becomes the white blackboard surface, not only available water-based in the surface of the white blackboard that this method is made but also available oil pen write, all very easily wipe, and the wear resistance height can use for a long time, is difficult for the scratch flavescence.
The method of manufacturing wear-resistant white blackboard provided by the present invention comprises the solution ceramics glaze is sprayed on the surface of steel plate and forms through sintering at a certain temperature.
Wherein the solution ceramics glaze comprises ground-coat enamel and cover-coat enamel in fact.
Consisting of of ground-coat enamel wherein:
High sintering temperature glaze: (860 ℃) 100 parts
Middle sintering temperature glaze: (830 ℃) 100 parts
Sintering temperature and low glaze: (780 ℃) 100 parts
8.0 parts of silica powders
7.0 parts of clays
7.0 parts in white material
0.1 part of borax
0.1 part of Sodium Nitrite
52 parts in water.
Consisting of of cover-coat enamel wherein:
100 parts of whiteware enamel glazes
0.2 part of KCI
6.0 parts of clays
50 parts in water.
Wherein the used temperature of sintering is about 810-820 ℃ to ground-coat enamel, is about 780 ℃ to cover-coat enamel.
Make the following routine processes of steel plate process: the routine processes liquid temp (℃) 1. degreasing 3-5% acid of time (branch), soda
0.2-0.5% surfactant 70-80 15-20 2. warm water washing 60-70 2-3 3. clear water washing 1-2 (circulating water) 4. sulfuric acid scrubbing 6-8 % by weight sulfuric acid 60-70 3-5 5. clear water washing 2-3 6. nickel process 0.5-1.2 % by weight sulfuric acid 60-70 3-5
(PH=3-3.5) 7. clear water washing 2-3 (flowing water) 8. in and 3 grams per liter soda water 60-70 3-5
1.5 gram hydrous borax 100-150
The manufacture method of wear-resistant white blackboard of the present invention can be learnt by following Fig. 1 is clear.
