Paint Coatings and Practices
First, re-soiling (replenishment ratio of 100:2 about take an egg quantity plus a peanut amount evenly mixed) after about 2 hours can be filled with 150 times water sand
Flat primer diluted with banana water, about 5% added, need to be stirred evenly before use) such as the use of a hardener 4:1 ratio of two degrees bottom, the main agent 75 cc and 25 cc hardener added about 5 to 10 cc banana water dilution) (second base or flat primer its function has to avoid refrigerant directly after painting the soil to produce soil marks, and seal the bottom to avoid foaming depression, also has a scratching effect).
Three, about 2 hours after grinding - using 400 times water sand grinding - finally can use 600 times water sand slightly modified - can reduce sandpaper traces -
4, dry after - will not need to paint part of the masking - clean preparation paint part, clean use of dry cloth plus degreasing agent wipe, wipe will be volatile, remove the coating Surface oil stains, etc. -
5, spray paint (about 70%, the proportion of about 1/4 spray cup paint plus 3/4 paint special banana water dilution - spray 3 to 4 surface paint) - spray paint about 10 minutes dry, at this time can use wipe cloth (sticky cloth) gently wipe - itself has a sticky dust.
6, inter-grid 5 minutes after the spray of gold oil layer (about 10% with paint banana water dilution, the use of 2:1 ratio of gold oil on 100 cc gold oil plus 50 cc hardener plus about 10 cc to 20 cc paint banana water dilution) - the first wet coating (small paint volume, large wind volume to show fog surface - about 10 minutes after wave Road gold oil layer (paint volume is large, air volume is small, this method can avoid a wet spray to produce a drop-off phenomenon -
7, the next day can be grinding wax (using 1200 or 1500 water sand branding with coarse polishing) -
8, the construction of each process to ensure complete dryness to avoid water residue, it is recommended not to be in sufficient water or rainy days construction.Metal Construction Method (Japan Metal Surface Treatment Agents
First, this metal treatment agent is suitable for any metal material, or the vehicle repainted, the paint has been d'ached off the entire plate gold use. If the paint itself is in good condition, not foaming depression embroidery, can use about 1000 times the surface of water sand grinding can be straight on the paint gold oil, do not need to use this agent.
II, Japan's original ROCK metal surface treatment agent (ratio of 4:1) main agent 100 cc plus hardener 25 cc use, using paint grade banana water added about 5% to 10% dilution (main agent 100 cc added about 10 cc banana water dilution.
3, japan's original ROCK metal surface treatment agent used in any metal material, after coating about 15 to 30 minutes can be sprayed on the paint, do not have to wait until the next day. When used, only a thin surface needs to be sprayed with a thin amount of fine use.
Plastic primer (pin primer use required)
1, plastic primer for any unpainted, or has been painted but worn, or its own paint condition is not good has been painted (or foaming) need to be repainted and other plastic materials, before use is recommended to use degreasing surface wipe drying to avoid the production of wax points or attachment bad situation.
, plastic primer action in the formation of the coating and paint between the production of media, to avoid the paint phenomenon. Generally new factory models are used.greasing agent construction mode
to mark huai work life, degreasing agent before soiling also need to be used, clean surface oil or grease, but usually will be omitted, before spraying paint will be used degreasing part of the paint to wipe, remove wax, oil and hand grease to avoid spraying the paint behind the wax point (commonly known as fish eye) or particles Dust, after wiping to be evaporated can be directly sprayed
galvanized soil (plate gold refrigerant)
1, galvanized soil (ratio is about 100:2) main agent 100 plus hardener 2 use (about an egg amount plus about a peanut amount hardener), when used will be refrigerant and hardener fully mixed.
II, galvanized soil for plate gold or metal material objects, direct metal contact, such as the requirements of the perfect person can first use metal surface treatment agent bottoming and then on galvanizing soil, improve the attachment force. The temperature of 25 degrees to 28 degrees about 30 to 60 minutes after grinding
plastic refrigerant
1, plastic re-soiling (ratio of about 100:2) main agent 100 plus hardener 2 use (about an egg amount plus about a peanut amount hardener), when used will be fully mixed with soil and hardener, how much mixture.
II, plastic soil can be directly used in plastic materials, because it is relatively fine , generally after the plate gold re-grinding at the plastic re-grinding again, to fill the plate gold re-grinding after the production of thicker grinding marks and holes.
3M no-tune fine soil
First, this soil for the anti-drying hardener self-drying fine soil, used to fill small scratches, hole use, use directly to make up can be, convenient and fast, generally used for re-grinding finished or second-degree bottom spraying Huai ready to paint before, found that there are not obvious holes to use, such as holes too large or deep, it is recommended to use adjustable soil repair, and then use this fine retouching
Do not exceed 0.3 mm, to avoid filling too thick holes at a time, hardening too slowly to produce the outside dry inside the dry situation, after a long time caused by the filling of the soil bubble bulge or depression, if the depth is thicker, it is recommended to fill in batches, the first fully hardened after the second road, according to Order to fill the
second-degree primer (grey primer, flat primer, gray primer
first- and second-degree primer with anti, fill holes, increase the attachment of the paint and plate, seal the soil to avoid foaming depression due to re-filling, The most important thing is to avoid the paint after the resulting soil marks (because the soil itself absorbs paint).
2, second-degree primer can be divided into the need to add hardeners and do not need to add hardener type, the same difference in the role is hardness, such as spraying small area, such as locomotives, or small parts of the plate gold, you can use a single liquid type, such as spraying larger areas such as the bonnet or the entire body recommended to use dual-liquid type, hardness will be higher.
3, flat primer diluted with banana water, about 5% added, before use need to stir evenly) such as the use of a hardener 4:1 ratio of two degrees bottom, the main agent 75 cc and 25 cc hardener added again About 5 to 10 cc banana water dilution) (second-degree bottom or flat primer its function has to avoid the soil after re-painting directly produced by the soil, and seal the bottom to avoid blistering depression, but also to fill the pore scratching effect. Single liquid type only need to add baking paint with banana water ratio with the same as two liquid type.
paint paint (general paint can be divided into three types)
1, once practice: paint directly add hardener spraying, no longer need to apply gold oil layer protection, but only plain paint, such as taxi yellow, truck blue and so on (advantages: save Time-saving materials, shortcomings: poor weather resistance, itself no gold oil protection when polishing directly grinding paint)
2, the second practice: after the finish of the paint need to be on the gold oil protection, the current car models mostly use this practice
Pearl paint, finish the finished paint after the bottoming and then a layer of pearl layer and finally on the gold oil protection, such as LEXUS model pearl white paint use method:
(i) about 70% to 75% proportion of the paint banana water dilution, about 25 cc paint Add 75 cc paint banana water, proportion
(ii) on no fixed, because people can use the habit, spray about 3 to 4 channels, spray distance of about 30 CM, spraying process
(iii) can adjust the amount of paint and air volume of the spray gun, Adjust itself to its best state.
(iv) paint poured into the spray gun spray cup can be first put on the filter, filter out impurities.
gold oil
gold oil ratio of 2:1,100 cc gold oil to add 50 cc hardener, and then according to personal habits to add 5 % 10 % 15 % of the roasted banana water, such as 100 cc gold oil about 5 to 10 cc painted banana water dilution. The first wet coating (small amount of paint, large amount of air to present a fog surface-like - about 10 minutes after the evaporation of the second wet spray second gold oil layer (paint volume, small amount of air, this practice can avoid a wet spray to produce a drop-flow phenomenon- (above gold oil construction) The method is applicable to any of the company's gold oil products soiling appliances and other consumables
1, scraper (replenishment board) for hard plastic material, for scraping flat to make up soil
2, horseshoe-type soft tonic plate for soft rubber material, can be used for re-arcing. Bend and make up a small part of the soil for use.
, water sandpaper. Can be in accordance with the secondary practice of the construction process to buy.
, G3 crude: after spraying gold oil the next day hard with wax polishing, can remove impurities on the surface of gold oil, flat gold oil surface orange peel or flow problems.
5, wipe cloth (sticky cloth): after spraying the finish paint use, paint spraying after about 10 minutes will be dry, the surface using a sticky cloth (itself has viscosity) gently wipe on the surface of the paint, do not push and wipe vigorously, by the sticky cloth on the sticky glue off the surface powder layer, paint powder.
6, non-trace tape: generally 14 mm and 40 mm two kinds, spraying glass, etc. do not need to spray, tearing off can avoid residual glue marks.
7, filter: for the filter surface paint gold oil filter mixed use, for the double-opening type, when using the side knotted after the sleeve on the spray cup, directly poured into the gold oil or paint, can be sprayed.
8th, water sand: this store for the plate spray special Japanese water sand, each commonly used pan number has, convenient grinding soil, second-degree bottom use.
9, 600 black heat-resistant paint: can be sprayed on the exhaust pipe, with 600 degrees heat-resistant effect, add banana water dilution direct spray.
