How is the strength of the paint produced?

To the strength of the coating is good, first of all, the coating on the substrate adhesion is good. The better the strength of the coating, the better the adhesion of the coating to the substrate, otherwise it is not possible to talk about the strength of the coating, which is a prerequisite.
let's get the

.
first example: a balloon without air has no strength. The air in the air is also not strong. We filled the air into the balloon, which rose and produced strength.
this process we concluded that the yin (balloon) restricts the yang (air), the yang gas enters the yin, the yang joins the yin and rises up, the intensity is produced.
this process we concluded that the yin (balloon) restricts the yang (air), the yang gas enters the yin, the yang joins the yin and rises up, the intensity is produced.
Let's take a second example: add 100g 1000 purpose heavy calcium powder in a cup, the heavy calcium powder is not strong, to the inside drop added flax kernel oil, the flax kernel oil is also no strength, side-by-side stirring, until the heavy calcium powder suction value, flax kernel oil just glued together the heavy calcium powder, heavy calcium powder by the flax kernel oil and rose up.
this process we concluded that the yin (heavy calcium powder) restricts the yang (flax kernel oil), the yang gas into the yin. The sun is yin and up, and the intensity is generated.
in the second example, if flaxen oil is replaced with acrylic, or aolate, then the strength will be higher. This indicates that the strength of the coating is related to the resin (yang).
above can be better explained by the classics of Chinese culture:
1 easy words: "one yin and one yang."
2 moral saying: "Everything negative yin and yang, gas for the same."
3 Huangdi inner scriptures: "Yin inside, yang guard also, yang outside, yin also." "
4 theory cloud: "and different."
the above four sentences are a meaning, but the expression is different. Why does our traditional culture emphasize yin and yang so much? Because yin and yang is the fundamental composition of things, when a person can grasp this fundamental will not make a general directional mistake.
the conditions under which the coating produces strength
1, yin
2, yang
3, yin and yang interaction
when the interaction between yin and yang is in equilibrium, strength is the best.
Application of yin and yang strength law
olic acid paint
because the alkyd resin (yang) is relatively soft (poor strength), the joint ability is very strong, so you can add a large number of fillers (yin) such as talcum powder, calcium carbonate to increase strength. This is China's famous toned paint, cheap.
furniture paint with fine silicon micro-powder anti-wear
furniture paint on wear resistance requirements are very high, the amount of resin paint is sufficient (yang), but wear resistance is not enough, add a small amount of very fine (yang) silicon micro-powder (positive very heavy yin), can greatly improve wear resistance.
Nitro paint using plasticizer to reduce strength
Nitro paint using nitro cotton and alicic acid resin flattening (yin), strength is still too large, easy to crack, adhesion is also poor, add a small amount of longer fat chain (yang) phthalates small molecules (yang), can slightly reduce strength but significantly improve flexibility.
Amphetamine emulsion can greatly improve the scrub resistance of latex paint
in the building latex paint, although the weather resistance of pure propylene emulsion is better, but when more than 30% of the styrene content of phenyl propylene emulsion instead of pure propylene emulsion, scrub resistance is greatly improved.
this is because styrene has less hydrogen in the styrene ring (biased yin) than MMA monoliths, and better binding force of fillers (3, yin and yang interaction), resulting in increased strength.
good polishing of putty
how can we achieve good polishing of putty? One is less resin (yang), so that the filler can not be fully linked, and the other is to use more talcum powder (yin), because talcum powder is flaky, large amount of oil absorption, not easy to arrange very neat (yin).
other
the strength of the synthetic resin itself is also based on the yin and yang principle design.
