The characteristic of the spray construction that the car repairs reachs skill
From;    Author:Stand originally
The characteristic <BR> car of the spray construction that <P><FONT&nbspface=Verdana>1, car repairs repairs the construction with other sphere too same, for instance, do not use commonly here brush besmear, roller besmear, dip besmear, drench besmear and high pressure do not have the construction pattern with the other familiar circumstance such as gas spray, use below most circumstance compress air pulverization spray. If be about to repair what car uses is metallic glitter lacquer, it is clear to understand even this car is when lacquer of face of spray of factory of car general assembly, whether did last impression use electrostatic spray when lacquer construction. If be, also should use the means of electrostatic spray when repair so, the way that because repair the aluminium powder in the coating of construction,ranges the likelihood otherwise and former outfit coating are different and cause off color. The besmear outfit of <BR> vehicle maintenance and repair and the besmear that the car produces manufacturer install product line to differ. In spray paint this on the requirement of working procedure, although cannot say its requirement wants a few lower, but the specialty that also has it, for instance handy easy travel, changing size of kind of area of convenient, spray and major time is intermittent type operation. Because this uses traditional spray gun,satisfy majority car more easily to repair the requirement of construction it seems that. <BR> as the metal is flashy in recent years the rapid growth of lacquer and bead light paint, the car is more and more luxurious, the car repairs the function of coating to also rise ceaselessly, such demands to spray construction also must rise accordingly. Accordingly, metal of spray light color flashs Qi Yupen besmears brunet metal flashs lacquer comparing rises, be about to be gotten high in the requirement of construction respect much. The quality such as the construction stability of lacquer of glitter of light color metal, chromatism controls a respect to be put in the difficulty of different level, especially its alleged along with horny different light sex of contamination of waste enamel compares brunet Qi Yaomin to feel more. It is so when lacquer of glitter of metal of spray light color, more should strict the besmear of construction essentials control that repairs lacquer according to introduces car installs condition and technology. Alleged operation accepting a margin should have when the lacquer man of skill <BR> gush that the margin accepts when <BR>2, car repairs spray paint is undertaking stain repairs the brim embellish that perhaps making a new spray layer and old coating to machine. The means that accepts a margin is walking along a gun not to buckle dead trigger in the begining, that is to say, the right now amount that offer lacquer is very small, as the shift of spray gun, increase the amount that offer lacquer gradually, until when walking along a gun to end soon, unlock trigger again, make decrease greatly for Qi Liang, obtain a kind of special transition thereby the operation of the effect. Its provide gymnastics to make a method be as follows: (1) smoothly mobile spray gun, arrive adjacent when treating surface of spray base material, pull trigger to undertake spray gradually. Next abrupt but put <BR> smoothly to open trigger, spray gun continues to move. This is from the gush inside extroversion. (2) make spray gun park needs upper part of surface of spray base material, buckle dead pull smoke undertake spray. Move smoothly outwards next spray gun, when once spray gun is adjacent,controlling border area territory, unlock trigger slowly. The operation wants smooth, continue to move next spray gun. This is from the gush outside introversion. The technical essentials <BR> that <BR>3, car repairs spray technology (1) hold a gun. Spray gun relies on the palm, big toe, little finger and ring finger to handhold, middle finger and forefinger in order to pull trigger. What some spray paint are versed in is longer when the job, change from time to time the kind that holds a gun, cooperate a little finger with big toe, palm merely sometimes, it is to cooperate ring finger to hold a gun sometimes, middle finger and forefinger are used buckle trigger. Can alleviate so fatigue, improve labor efficiency. <BR> (2) spray gun is right the azimuth of base material surface. Spray gun should keep perpendicular to base material surface, perhaps keep perpendicular as far as possible. If spray gun has a bit askew, its can cause spurt necessarily as a result take deflection to flow at the same time drip, and across appears bony, be short of lacquer, cause striation coating extremely likely. <BR> (3) the spray gun distance at base material surface. To siphon type spray gun character, optimal work space is 15~20cm. If the distance is too close, likely generation shedding drips, flash may be caused even when lacquer or bead light lacquer in gush metal color is as abhorrent as what anticipate. If be apart from too far, exceed 20cm, cause dry spurt possibly, spend in season, make of coating shed smooth sex to become poor. If of spray is metallic glitter lacquer, put possibly also in the possibility that color changes. Press spray gun sending form to be able to leave base material a few further. General and optimal distance is 20~30cm left and right sides. These are the basic principles that must follow when spray construction. <BR> (4) the floating rate of spray gun. When spray, the influence that the floating rate of spray gun installs the effect to besmear special big. If spray gun is mobile too fast, the surface appears bony, stream the difference that make the same score a gender, coarse; If spray gun is mobile too slow, the coating that forms is too thick, extremely possible generation flows hang. Once spray ends,rate of shift of optimal spray gun should be, new spray layer appears plump it seems that, embellish is wet, both neither bony, barren, also divide load one's writing with fancy phrases nevertheless. Anyhow, the floating rate of spray gun should decide according to the particular case of construction site. Say commonly, it is relatively relative word merely, the spray gun that uses the floating rate when pressing spray gun sending form to want otherer than using type is a few faster. <BR> (5) the control of trigger. Spray gun is to rely on trigger to come pilot. Trigger is buckled more greatly, liquid velocity of flow is larger. In the course that takes a gun in the tradition, trigger always is buckled dead, is not to be buckled partly. The coating with the ejective place when ending soon to avoid to take a gun every time piles up, the gush lacquer man that has experience should loosen a bit trigger slightly slightly, offer Qi Liang in order to decrease. The note <BR> of construction of the spray when <BR>4, car is repaired (1) the spray order of car of entire in season. To car of entire in season, before entire in season, answer to plan the order of good spray first. The arrangement of spray order is reasonable, have very big effect to the quality of paint film and burnish. <BR>1&nbsp is opposite above all the more inaccessible place in spray, if li of layer of the brim, boot, aperture and door is reached inside bonnet, undertake spray first. When gush doorcase, the door should maintain open account a bit, make dirt cannot fly upwards to car appearance and caustic and outside lacquer are in. The airiness direction between <BR>2&nbsp spray paint is arrange a car by coping two side and flow direction is bottom, accordingly, spray order should first car coping, come again by the side of the door that open wide, circle bodywork to return door to be in again next. Can solve around foreword spray to receive a gun to be in generation so " the gun is beautiful " make lacquer face appears " loss of gloss " phenomenon; Around foreword follows spurt, the jackknife that can eliminate perpendicular appearance receives head mark. <BR> (2) the spray of metallic glitter priming paint. When the car is repaired, metal of general requirement spray flashs must make sure film color is consistent after priming paint, every gush jackknife must achieve 3/4, floating rate wants even, must not go out to jump now the phenomenon such as gun, leakage gun. After spray ends, beard examination is truckload whether does color appear inhomogenous phenomenon, be like occurrence color inhomogenous phenomenon, can continue to have use reduce viscosity, undertake lacquer mist law amends inhomogenous place spraying. To obtain a metal flashy priming paint does not appear in spray construction inhomogenous phenomenon, should notice: Before <BR>1, spray, to must be being used by gush content face 2 priming paint close, prevent to produce off color; Before <BR>2, spray, need good to already was being made up lacquer stuff to have mix, in order to prevent metallic quality heavy base; In construction of <BR>3, spray, coating must be used spray lacquer mist law, lacquer layer cannot gush is gotten too thick; <BR>4, thinner should use wash-and-wear dissolvent, before working in order to reduce paint film shed smooth sex; <BR>5, general spray makes an appointment with 2~3 layer, it is equably with whole cover, color accurate, every time interval should grow relatively a few; <BR>6, must choose the spray gun with spray lacquer even mist, prevent generation " jump gun " phenomenon. <BR> (3) passenger car and minibus spray colored ribbon. Passenger car and minibus automobile body use 3~4 to plant commonly color, and the back wall before two side reach automobile body is designed have clipper-built straight an outline and the geometrical appearance of the horn that show wedge. Accordingly, the light lacquer of good in spray passenger car and minibus undertakes lineation after film, stickup not spray part, be in stickup before use 280~360 date waterproof abrasive paper to needing spray part fine arenaceous, in order to enhance the adherent power between two levels lacquer. To the design of above of two kinds of color, still need to be over in gush ribbon of the 2nd kind of color is waited for after paint film is dry, have the 3rd kind of stickup cover before be the 4th kind of color again, till the spray of belt of color of avery kind of ends. &nbsp</FONT></P>
