2017-3-21 23:49:01
Nano coatings with crosslinking agent, corrosion resistance evaluation is based on nano composite filler for making sample of salt spray test (KSM ISO11997-1), not using the example of glass flake after 200 hours, the surface bubbles, rust, cracks occur. Using glass flake is 50 times in 300 hours after repeated cycling test, the surface no bubbles, rust, crack phenomenon happens.
Using elastic resin (NBR) in cavitation erosion experiment, comparison with other test plate, we can find the material has the advantages of the noise reduction. Also can use stainless steel (SUS304) test sheet cavitation erosion test results can confirm development product of cavitation erosion resistance.
Especially all test plate surface and contrast microscope, every little erosion of time and space in the trial of a superior abrasion quantity data comparison results, we can confirm product development because there is almost no corrosion and foaming phenomenon.
By the high elastic NBR modified epoxy resin and film type glass flake packing of this product is a kind of in order to solve the water jet impact caused by cavitation erosion and wear of organic and inorganic composite material, NBR modified epoxy resin is a kind of synthetic resin of high elasticity, plasticity and the characteristics of strong water resistance.
Especially high adhesion of the material and the parent metal, high elasticity, so the hardening of volatile matter and volume shrinkage ratio is small, has good mechanical properties, chemical resistance and response performance.
In addition the crosslinking agent with low viscosity polyether amine resin, pigments mixed strong, plasticity, bending, impact resistance and drug resistance good, stimulating and weak smell, but also has very good adhesion. Product development of surface hardness is poured itself must be flexible to increase the cavitation erosion resistance to reduce the hardness of the material.
Product hardness can be as NBR modified resin and polyether amine, the deployment of polyamide crosslinking agent to adjust the use factor.
In order to make the film type glass flake mixing in the high elastic resin, coupling agent is added in the products we make glass flake almost parallel arrangement in the coating. This product use inorganic filler - the size of the thickness of the glass flake is 0.1 ~ 0.2, the size of 20 ~ 30, and comparing existing micron grade packing coating agent, strength and elongation at break is more outstanding, is close to nanoscale physical characteristics of packing with abrasion resistance.
So we can demonstrate our product has outstanding resistance to corrosion and the cavitation erosion resistance. Through as shown in figure 2 can learn make corrosion penetration factor through nanoscale fillers coating longer distances.
Chinese name: Diethyl toluene diamine(DETDA)
Diethyltoluenediamine packingļ¼ 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).
Nanoscale plate type glass flake filler in the resin evenly arranged on the process of raw materials mixing, the generation of air bubbles, viscosity rise of extremely difficult to control the flow of modification, raw material prices, such as relatively few problems, so you can look forward to working with existing products compared with strong price competitiveness.
Glass flake compared with other pigments oil absorption is not high, input doesn't make the viscosity rise after mixing, the inside of the filler in the resin array effectively block the penetration of the water, oxygen and other external factors. The inputs accounted for about 5 ~ 10% when the most outstanding performance of the resin, more than 10%, the development of mechanical strength will be lower.
Plate type of glass flake layers within the resin evenly arranged, quadrangle material for silica powder, gray for adding titanium dioxide powder.
In general on craft despite the difficulty of mixing nano filler but the product of the glass flake is evenly dispersed, cavitation water jet impact on the material surface, and glass flake filler effectively to disperse the impact to improve the wear resistance. Besides glass flake and larger than the diameter of the water jet, is more advantageous to disperse water jet impact energy.
Cavitation water jet diameter of mostly dozens of micron to a few nanometres wide category, in order to solve the problem if the size of the glass flake as a few millimeters, produces elastic resin mixed with difficulty, rough surface coating and glass flake easily fracture, parallel distributed array difficulties and other issues. In addition coating on the surface roughness is higher, the more prone to corrosion wear. Using plate glass flake size and shape of the packing is the most appropriate.
