Instructions
Mixing and maturing of coatings
Ceramic non-stick coating is a semi-finished coating, which needs to be mixed and matured first, and the general atmosphere (ABC) 3 or (ABCD) 4 components:
· Pour solution C（CD) into
solution B and mix thoroughly;
Then fully roll stirring
(300r/min stirring for20min);
· At the same time, the A solution is
roller-stirred until there is
no more precipitate
(300r/min>20min);
· The BC(BCD) mixture was
poured into solution A
and rolled(300r/min) maturation；
Maturation time:
Summer: 8h, Winter: 12h
Requirement on pre-treatment
· Firstly, degreasing at high-temperature, then wash with 1%~3% NaOH solution (60℃) for more than 6
minutes, dry it after water rinsing;
· Blast with 80#~120# corundum to make the surface roughness reach 2.0 μ ~3.0μ, pay attention to
sandblast evenly;
· Wash with 1%~3% NaOH solution(60℃) for more than 6 minutes, rinse with water;
· Wash with 1%~3% hydrochloric acid solution (60℃) for more than 6 minutes, rinse with water and dry.
Preparation of the coating
· The
primer mid coating and top coating must be fully dispersed before
operation. Rolling the coating at the speed of 30rpm with rolling machine for 30min. Checking
the bottom of bucket without precipitate, agglomeration. Be careful not to exceed 60min;
· Coating filtration: filtrate the coating with screen (100mesh) before using.(Except the topcoat)
Application
The spraying environment should be dry, well-ventilated, without dirt, recommend using dedicated
spray gun, elevated tank and curing oven;
· The air compressor should be degreased, dewatered and equipped with water oil separator
before using;
· Adjust atomization and oil pump capacity of the spraying gun; make sure the unit is clean and flat;
· Make the pretreated substrates clean before spraying;The pan spraying primer, primer coat could be sprayed
with normal spray gun; after primer, top coat should be uniform, then increase the temperature to 280℃
gradually and keep for 8min ~10min; control the dry film thickness of the primer and top coat in the
range of 35μm~45μm.
The oven (or the tunnel drier) must be well ventilated, with good conditions to meet requirements of
temperature: about 10 minutes for temperature increasing, enough curing time; otherwise, it will lead
to color change of coating.
