Solventless high solid coatings crosslinking agent
2017-4-2 11:38:16
Solventless high solid coatings crosslinking agent, based on long chain alicyclic amine, not only increased toughness. And low volatile, reduced the irritating to the skin, at the same time introduced in the molecular structure of crosslinking agent on crosslinking promoting effect of hydroxyl to accelerate the crosslinking.
People mouth say normally paint just paint a, now has solid and liquid coating. In the object surface coating paint with functions of protection, decoration and other. Coating construction technology through the development of science and technology are also changing, below the author to introduce liquid coating and coating of solid what are the differences between process? Hope to be of help.
Besmear brushs paint most widely used, but the coating efficiency is low, the scale of production reach a certain degree, the production efficiency have certain requirements of the factory, can't stand this way of the original coating.
Spraying machinery and electronics industry is the most widely used coating technology, and all the coating process of the most polluted in the process. Is to make the liquid paint to spray mist and spray to the object surface, form a coating method. On the basis of the principle of the tools used by different, they are divided into perfume spray and airless spraying two kinds.
Airless spraying, also known as high-pressure airless spraying, it USES the high-pressure plunger pump to paint in the squirt gun atomization air flow ACTS on the surface (metope or wood surface). Airless spraying, compared to the perfume spray paint evenly, no sense of particles. Perfume spray, also known as low pressure spray have spirit, it relies on low pressure air make paint after the squirt gun atomization air flow ACTS on the surface (metope or wood surface).
Perfume spray is relative to the hand brush, brushless, and relatively uniform plane, unit work time is short. Also note that if the metal surface spray coating treatment, it is best to use metallic paint (enamel). In the process of spraying, due to the effect of compressed air, can produce a large number of "paint", floating in the space of the construction work; "Fly" paint adhesion on the roof of the workplaces, walls, settling into the ground, forming "paint slag. Spraying technology on coating the utilization rate of about 50%.
Dip coating is mainly suitable for small cores. Varnished is put all immersed in the paint in the container, after a short time, again from the slot, and redundant coating liquid flow back of the tank in the coating. Varnished don't fly "paint" problems, but there are solvent evaporation and the ground a few drops of paint. Dip coating process on the utilization rate of the coating is higher, at 70% ~ 80%. Dip coating thickness should not be guaranteed, sand core and coating thickness difference is significant, does not apply to cast.
Chinese name: Diethyl toluene diamine(DETDA)
Chinese alias: aryl, aryl diethyl - aryl - methyl-p-phenylenediamine
English name: Benzenediamine, ar, ar-diethyl-ar-methyl-English aliases:Diethyltoluenediamine; ar, ar-Diethyl-ar-methylbenzenediamine;Diethylmethylbenzenediamine;
CAS No. :68479-98-1
EINECS No. :270 -877-4
Molecular formula: C11H18N2
Molecular Weight: 178.28
Boiling point: 310 ℃
Refractive index: 1.581
Flash Point: > 140 ℃
Inchi: InChI = 1/C11H18N2/c1-4-8-6-7 (3) 10 (12) 11 (13) 9 (8) 5-2/h6H ,4-5,12-13H2 ,1-3H3 density : 1.022
Risk Codes: R10; R35
RIDADR: UN 3082
Safety instructions: S2; S26; S39; S61
Packing Group: III
Hazard Class: 6.1
Widely used in sand core flow coating and coating of medium and small mold coating. Flow coating is pumping at 0.02 MPa to 0.2 MPa squeezed out from the nozzle, the pressure will paint coating on the transmitter on the workpiece. Excess paint, overflow return to reservoir recycled rain drops. No brush marks in the coating, smooth surface, high surface quality, save paint, small pollution to the environment, not only suitable for sand core, applies to cast. Although flow coating is solvent evaporation, flow coating process of coating the utilization rate of as high as 95%.
Single or double roll coating used in sheet or strip high-speed continuous mechanical coating. It will touch with spin coating of paint roller coating "transfer" to the surface, forming the required thickness of paint film.
Roll coating can improve the capacity and output, reduce production cost, rich colors, different batch consistent product quality, can achieve a variety of surface effect, the process of flexibility is good, but must be strictly controlled release coating thickness.
Curtain coating is mainly used for coating sheet or strip. Coating with pumping or gravity overflow make curtain "paint" by adjustable gap formation and coating on the surface. Curtain coating paint loss of at least one high speed coating process.
Roller coating or rotating drum coating can effectively control the precision of the plank, flatness, successfully eliminate the bump and wrinkles caused by traditional, so often used in single weight is less than 0.5 kg of screw, nut, screw, such as small parts. It is to a certain amount of coating splashing in serving the workpiece or rotating drum drum, make the paint evenly to a kind of technology on the surface of the workpiece.
