For a long time, the technical requirements for automobile spraying were the highest. Therefore, automotive spraying technology represented the highest level of spraying technology in the world. As early as the 1980s, the spraying level of China's automobile maintenance industry still lags behind. Until the early 1980s, SATAFarbspritztechnik GmbH & Co.KG, established in 1907, is a leader in the world's automotive spraying equipment industry. Year), the first to introduce two German Sata paint spray guns (SATAjetB and SATAjetH) to the Chinese market, has been more than 20 years of history. Due to its SATA spray guns, the SATAjetB (traditional pot top spray gun) and the SATAjetH (traditional lower pot top spray gun) are both superior to other similar products in terms of spray quality and coating performance. Paint spray guns have so far been popular with Chinese spray masters. I. Current mainstream spray guns on the Chinese market: Conventional topcoat spray guns for high-pressure atomization technology (SATAjetB, SATAjetH) SATAjetB (traditional top coat spray gun) and SATAjet H (conventional bottom coat spray gun), the best spraying pressure is 4 bar (about 4kg/cm2), (according to the gun's inlet pressure), the paint on the hood The atomization pressure is about 3 bar. The two paint spray guns use high-pressure atomization technology to uniformly atomize the paint through high-pressure compressed air injected through the air atomization holes on the air cap. When the paint (paint) is sprayed on the workpiece to be sprayed, it is affected by the high-pressure atomization air flow, and part of the paint mist rebounds. After the bounce, the paint mist is lost to the air. Thus, the paint transfer efficiency (painting rate) About 45%, which is common to all conventional spray guns of the same type. Since the 1990s, with the strengthening of environmental protection awareness and regulations, the international major automobile companies have begun to use environmentally friendly coating materials, so that the amount of harmful volatile substances emitted by the coating during the spraying process meets environmental protection requirements. Therefore, Automotive paints are gradually moving toward high solidification, water-based, and low-VOC emissions. The EU has also proposed amendments to reduce the use of volatile organic compounds (VOCs) in automotive painting, metal decorative paint, and varnish by 50%. For waterborne coatings, the VOC content per liter is controlled below 50 grams, and the solvent-based coating is controlled within 750 grams per liter of VOC. In Europe, some experts also pointed out that VOC is the direct cause of photochemical smog and has begun to cause serious problems in the EU. Air pollution can cause throat and eye pain and breathing difficulties in humans. In addition, the photosynthetic function of plants will be reduced in the natural environment, resulting in reduced crop production. Second, a new generation of spray guns: High-Flow Low-Pressure (HVLP) atomization technology of the Environmental Protection Province paint top spray gun (SATAjet2000HVLP) In order to cooperate with new European and American environmental protection regulations, the German company Sata, in the early 1990s, developed a high flow rate (air flow rate) and low pressure for the green paint and atomization technology (air cap atomization pressure). ) Spray gun, namely: HVLP (ie, H high, V flow, L low, P pressure) atomization technology environmental protection paint spray gun. This series of atomizing spray guns includes spray guns for various coatings or coatings, such as topcoat spray guns (SATAjet 2000HVLP), primer spray guns (SATAKLCHVLP), automatic spray guns (SATALPjetK3HVLP), and color point repairs. Small repair gun (SATAminijet3HVLP) and so on. Environmental Protection Province paint topcoat spray gun (SATAjet2000HVLP), suitable for products with high coating requirements, such as silver paint, pearl paint, varnish and plain paint for cars; nano-coatings; designed for specific properties of waterborne coatings. There is a special nozzle set for water paint (WSB stainless steel nozzle with a diameter of 1.25 mm). Unlike the conventional spray guns, the spray gun (SATAjet 2000HVLP) of the Environmental Protection Province Spray Gun does not rely solely on the air pressure at the air caps of the spray guns to atomize the paint, but instead matches the air flow sprayed by the spray nozzle atomization holes (spray pressure is 2.0). Gas consumption is 430 liters per minute for Pakistan. Perfect atomization of the paint. When the spray pressure is 2.0 bar, the atomization pressure of the wind cap does not exceed 0.7 bar. Because the atomization pressure is greatly reduced compared with the traditional spray gun, the paint mist rebounds and dissipates and thus the quantity is reduced, and the paint transmission efficiency is higher than 65% (according to European and American environmental protection) Regulations) vary according to the spray painter's method of spraying. The paint can be up to 10% or 30%. The loss of solvent and paint is greatly reduced, thus also protecting the environment. At the same time, the painter's health Also played a good guarantee. The use of the SATAjet 2000HVLP nozzle set with a diameter of 1.3mm will not change the characteristics of the paint when it is applied to silver paint and pearl paint in automotive paints, such as orderly arrangement of metal particles and pearls. The particle's magic effect and so on. If you need to increase the film thickness, such as spraying varnish and plain paint, choose a nozzle set with a diameter of 1.4 mm. The structural design of the Environmental Protection Province Paint Topcoat Spray Gun (SATAjet 2000HVLP) has resulted in a number of design patents, such as: stainless steel nozzles that ensure uniform atomizing air diversion; CCS color identification modules that use air flow technology design and facilitate gun management Device, QCC bayonet design for quick change of gun pot (only need to rotate 1/4 turn), and free-rotating air connector to prevent air hose from winding.
