bst3388贝斯特国外产品介绍(英文版)

1) chemical medium, gas, vapor permeability is much smaller than the glass fiber reinforced plastic lining, it is difficult to cause the phenomenon of water vapor diffusion, which is due to the overlapping layers of glass scales, so that the penetration of a long distance.

2) the shrinkage is low and the residual stress is small because of the dispersion.

3) the thermal expansion coefficient is small, the bonding thermal stress is small, the heat resistance is high, and the thermal shock resistance is good.

4) the mechanical strength is not glass steel lining, but wear resistance, scratch resistant performance good, mechanical damage is also limited to the local.

5 glass flake coating construction technology performance is also very good.

If the glass flake coating is only physical mixing glass flake and resin, their performance is not the best, but also relates to the glass flake section problem here, the mixed volume and method for mixing glass flake resin, selection, pretreatment of the substrate, the primer selection, construction method and a series of parameters is the key technology of glass flake. Table 3 the physical properties of the glass flake coatings are shown in table 4.

Table 3 varieties and characteristics of glass flake coatings

Application examples of 3 glass flake coatings in Japan

Because the glass flake coating has corrosion resistance, anti permeability, low shrinkage film, small thermal expansion coefficient, curing residual stress, abrasion resistance, simple construction, easy to repair, so the glass flake coating in the chemical industry, metallurgy, chemical, electroplating, construction and other industries have a large number of applications. Especially in a variety of marine engineering equipment, offshore oil and gas platforms, harbors and docks and ships more widely used. Now give a few examples of [5 ~ 7].

1) Japan Automobile highway concrete bridge of salt fog corrosion measures -- the coastal side every winter, the flying salt, regardless of steel or concrete structures, as Japan's most significant local damage. Japan Automobile highway concrete bridge, starting in 1972, and later was salt fog corrosion damage, 1987 began to repair, the epoxy glass flake coating and glass flake coating repair, film thickness 1000um. The same year completed from Niigata Prefecture on the city to Toyama Asahi town of 59.3km highway concrete bridge, in order to deal with the salt spray, using vinyl ester glass flake coating, the glass flake coating and coated with polyurethane resin coating and fluorine resin coating.

2) Okinawa area steel rust - Okinawa comprehensive investigation bureau of things in Japan steel professional association's assistance, the test of corrosion prevention painting series and wind sand abrasive, measured after 2 years, the best performance of glass flake coating, epoxy resin coating of chlorinated rubber coatings and phthalate type the poor effect of saturated resin coating.

(3) the steel structure corrosion prevention scheme of the bridge of the airport contact - the steel structure of the Kansai International Airport liaison bridge, and put forward the scheme of using glass flake coating. The longitudinal above replacement coating difficult after use, in order to rust permanently, glass flake coatings and polyurethane coatings are used, the film thickness was 1090um, the resin glass flake coating used is VE and epoxy resin. The coating of vinyl ester resin glass flake coating and polyurethane coating (1000um) in splash zone was put forward, and the coating of glass flake coating (1090um).

4) harbor steel rust - Japan coast development technology research center published in 1986 by the steel structure corrosion prevention guidelines, including marine atmosphere, seawater splash department, tidal and sea areas recommended vinyl ester resin, epoxy resin and coal tar glass scale coating.

5) oil tank bottom corrosion - Japan Okinawa oil base (Jin Wuwan) oil tank height 22m, diameter 80m, floating roof storage capacity is 100 thousand M3, but also the construction of the oil storage tank 2 million 100 thousand M3 and 5 million 100 thousand M3, the floor adopts the glass flake coating anticorrosion, glass flake coating using high polymer chemistry in Japan the company production of 5 years, the construction area of 1.5 * 106m2..
