1) titanium dioxide: be white pigment most important, best in coating.There is excellent opacifying power, whiteness and chemical stability.
Technical requirements:
Whiteness: >=95
PH value: 7-8
105 DEG C of fugitive constituents :≤0.5%
2) kaolin: whiteness is high, dry hiding power is excellent, and greatly can improve compared for and providing excellent look malleability energy of film, oil number is higher, and suspension is better.Partial-titanium white powder can be replaced, reduce costs.
Technical requirements:
Whiteness: >=90
PH：7
3) coarse whiting: suspension and the film smoothness that can improve coating, improves sticking power and mildew resistance, reduces paint blister and cracking phenomena.
Technical requirements:
Whiteness: >=90
4) talcum powder: the snappiness that film can be improved, reduce the water permeability of paint film, under the existence of WATER AS FLOW MEDIUM, the effect due to its hydroxyl can improve the sticking power of paint film, give the certain thixotropy of coating and weaken the sedimentation of pigment, contributing to the physical strength strengthening paint film in addition.
Technical requirements:

(5) technology controlling and process key point:
The dispersion grinding stage
1) in dispersion tank, first drop into water, pigment dispersing agent and other auxiliary agents, after stirring, throw face, filler again.
2) pigment of difficult dispersion should first be dropped into, the pigment that rear input is easily disperseed.
3) when needing to add multiple filler, by first drop into density less, the order of water regain is comparatively large, particle diameter is thinner filler carries out.
4) need measure temperature and the fineness of pigment slurry during grinding, temperature is greater than 50 DEG C, should stop stirring for some time, carry out telling dispersion stirring operation after temperature reduces again.Slurry fineness should control at 30-40 μm, till should continuing when 40 μm to be ground to and reaching regulation fineness.
Letdown phase
1) after adding polymer emulsion, need the pH value of test slurry, pH value is that 8-9 is advisable.
2), after adding polymer emulsion in pigment slurry, when system viscosity is reduced to rapidly Schwellenwert, defoamer is added.
3) thickening material must add in the final stage of paint, the viscosity 80-100Ku of adjustment emulsion paint finished product.
