Glass flake coating with crosslinking agent
2017-3-28 11:23:24
Glass flake coating with crosslinking agent,The coating due to like fish scales is called "glass flake. It is composed of glass and main film-forming, the glass flake to overlap each other, form the outside world has a strong resistance to corrosion medium to prevent the density of the coating, so as to achieve the strong corrosion.
It has excellent resistance to medium permeability; Good abrasion resistance, impact resistance; Excellent acid, alkali, salt, chemical features such as oilfield sewage. With a good bonding effect of matrix, and the thermal expansion coefficient is small, good temperature resistant poly degeneration, the highest resistance to 150 ℃ dry heat. Widely used in oil tank, sewage tank, pipe anti-corrosion, reservoir, etc., most of the steel structure anticorrosion protection.
The paint flow phenomenon:
A. white base surface uneven, complex geometry; B. gun and artifacts too close to the distance;
C. a spraying quantity too much; D. ratio of paint diluted doses too much;
E. construction environment temperature is too low; F. level interval time is not enough;
G. diluent volatilizing speed too slow;
Method of prevention and treatment:
(1) white base table processing level off, the geometric shape of complex workpiece several times to spray;
(2) spray gun and artifacts to keep 20-30 cm distance;
(3) reduce the amount of air pressure, control oil,;
(4) reduce the number of diluent, construction viscosity should be around 16 "(4 # cup);
5. If construction site temperature is too low, should control the temperature of the construction site for construction;
6 coating level should be in the first layer of paint film base table dry spray again after the second;
All landowners with quick dry thinners; 5, mold change color: this kind of problem happened on the wet paint surface more, such as water vapor condensation on the glass and metal surface often produce dark brown blotch. Can use antiseptic at this point, the part of the instruction that takes a manual handles mildewy, after waiting for mould to kill, clean surface clean, then, go up afresh again lacquer.
The reason that paint surface produces blotch is very much. For example: the material that the moisture in emulsioni paint dissolves a wall to rust and paint, the metope of using steel wool brush can produce rusty spot. Dark tube leakage shows blotch to wait inside the wall. To prevent blotch, can brush a layer of primer that contains aluminium powder first, if already appeared blotch, can handle emulsioni paint except decontamination spot first, after brushing a priming paint that contains aluminium powder, go up afresh again lacquer.
Primer paint lose luster: the reason is not, or priming paint and lining lacquer did not work directly with light lacquer, the result has a glazed lacquer is absorbed by timber and lose luster. Have a glazed lacquer is bad is also a reason. Wear old paint with dry wet amphibious sand paper, the dirt of brush away burnish, use wet cloth clean exterior rub-up, wait for dry after appearing, brush afresh again above lacquer. Pay special attention is, in air temperature very low environment lacquer, after paint film works, lose luster possibly also.
Chinese name: Diethyl toluene diamine(DETDA)
Diethyltoluenediamine packing： net weight 200KG/ galvanized iron drum (a small cabinet pallet loaded 16 tons), 1000KG/IB barrels (a small cabinet loaded 18 tons or 23 tons of ISOTANK).
Not fully paint orange peel, wrinkles: film flow show smooth which is dry reason:
1) paint too thick;
(2) the pressure is too great, the distance between nozzle and workpiece too close or too far;
(3) types of diluent improper;
(4) the environment temperature is too high;
Prevention and control, and the solution:
(1) the paint to construction viscosity (4 # cup) around 16 to 18;
(2) reduce the air pressure, the distance between nozzle and workpiece keep in 20 to 30 cm, don't spray paint film is too thin;
(3) the types of diluent used to form a complete set, choose appropriate slow dry solvent.
(4) adjust spraying room temperature, exhaust air flow control.
