Room of furniture spray paint applies mediumly in furniture spray

　　1, the common problem in furniture spray paint

Current, room of furniture spray paint is applied in the process of furniture spray paint widely, but because consider in actual application not, and those who purify a technology is not perfect, there is different question in each enterprise. Common problem has the following kinds:

(The design that 1) gives a platoon wind is unreasonable, cause spray paint to operate an environment to discharge wind effect not beautiful. Main show is to give wind to filter negative pressure of systematic block muscularity, generation, local have dead space. Rebound when spray paint works Qi Wu has contaminative appearance 2 times to panel, have certain effect to product quality.

(2) seeks the result that discharge wind one-sidedly, make the wind force that discharge wind and wind pressure too great, increased to equipment is thrown and run cost thereby. Be opposite especially northward carpentry manufacturer, winter still needs to heat send wind, the fan of wind giving a platoon is too big, the hot damage that cause is bigger also, increased an enterprise to produce cost thereby. Say commonly, when the design is calculated, suction inlet wind speed asks control is in 0.05m/s, the wind speed control of exit sending wind is in 0.35m/s, choose the model of fan with this.

(The intensity of illumination with the illume unreasonable, corresponding layout of room of 3) spray paint is insufficient, cannot provide favorable working environment to spray paint, still a few enterprises do not use the lamps and lanterns of explosion proof on the illume of lacquer room, bring serious safe hidden danger to production.

(Of 4) Qi Wu purify a method unreasonable, to doing the spray paint room of type, average company just is opposite the solid composition in Qi Wu undertakes primary processing, and the organic composition in Qi Wu is discharged directly in atmosphere, discharged standard amounts to mark far from, cause certain pollution to the environment. And to wet spray paint room, a few enterprises just also pass water act to come down lacquer mist bath, the liquid waste after waste residue clears is discharged directly, cause pollution 2 times to natural environment.

(5) also is put in a lot of problems when the design makes installation, the quality that be made to workpiece and installs is not high, put in air leak phenomenon, sealed to whole effect produces very big effect. Design in pipe fitting of wind giving a platoon at the same time also have particular problem, if the bend, umbrella that discharge wind is overspread, change the respect such as diameter wind canal.

2, the device of a few kinds of spray paint with furniture commonly used spray paint

Industry of furniture spray paint is different from the spray paint of the industry such as building materials, electric power, engine, the work of furniture spray paint is less and medicinal powder, but taller however to environmental requirement. A few manufacturer designed equipment of appropriative spray paint and room of special spray paint technically still in the light of carpentry industry. When choose, should the actual condition of mature production technology, say commonly, if be omnibus spray paint, to machining the furniture with environmental not high demand, introduce simple vent cabinet can, if the product to furniture is simple capacity demand is very high, can choose spray paint room. If furniture is measured big, and very tall to product quality requirement, should use equipment of automatic spray product line to wait. Anyhow, should in order to be opposite health of body and mind, discharge airy clean degree whether up to mark, and whether to have to product quality assure to serve as the main basis that chooses spray paint equipment.

3, design a principle

The design of spray paint room must satisfy manufacturing technology requirement, to corresponding equipment type selecting must safe and practical, ask the economy that use material observes and study at the same time, the appearance is even beautiful and easy. Still must accord with the relevant law laws and regulations of our country in addition. If level of noise of environment of GB3096 city district, GB7691 besmears,hold company of industry of exercise safe practice, GBJ4 3 useless discharge safety of spray booth of tentative standard, GB14444-93 technical regulation.

4, design installation and a few safe issues that in using, must consider

(1) because spray paint equipment is to belong to appropriative special device, must fulfil person specially assigned for a task to responsible open is shut and move so perambulatory.

(When 2) is designed, should consider to eliminate electrostatic. Because spray paint room gives a wind to filter of the system filter material is chemical fibber goods more, filter in giving wind and platoon dirt course the dust with material assemble very much collect, because attrition can produce phenomenon of more electrostatic, discharge,fall in the motivation of fan, if do not have electrostatic eliminate device to cause fire and explosion very easily. When if exceed building height,wind of dirt of the platoon outdoor is in charge of, still should consider to adopt avoid thunder measure.

(3) is right when the illume that designs lacquer room chosen lamps and lanterns, switch must explosion proof, lest be when open,produce risk.

(4) must choose explosion proof fan to discharging dirt fan, the noise that returns fan of Lv of take an examination at the same time cannot exceed bid.

(Economy should be chosen as far as possible below the premise that 5) asks in contented craft applicable model the fan of wind giving a platoon, at the same time the requirement gives wind fan should compare the wind force that discharge wind to wind force big 10% , in order to ensure Qi Fangwei is being pressed.

(6) must ask to go by the design when the installation that make, avoid to change blueprint at will, in order to assure the installation quality of lacquer room.

(The filter that 7) gives a wind the system and lacquer mist purifier want to clear regularly, cause to operation environment of the system in case destroy. Must build system of perfect and relevant care and maintenance, set person specially assigned for a task to be in charge of.

(The solid trash that 8) comes down to doing room of type spray paint to filter and wet lacquer room filters the waste residue liquid waste that come down needs course appropriate is handled, avoid 2 times to pollute.
