The concentration of solvents in the self circulating paint chamber should not be exceeded

Painting and drying electric power calculation heating system.

1. It has good ventilation facilities when painting, and the indoor wind speed meets the requirements of GB14444 93 "Safety Technical Regulations for Paint Spraying Room", and under normal working conditions, the indoor benzene series concentration does not exceed 100mg m3, which is far lower than the lower limit of 25.

2. All materials in the paint booth (including side panels and top filter cotton) are made of flame retardant materials.

3. Install a combustible gas alarm indoors to monitor the concentration of combustible gas at any time and take corresponding preventive measures.

4. Install an overpressure alarm device to alarm and stop the machine in the case of poor air supply or exhaust to avoid high combustible gas concentration caused by poor ventilation.

5. The lighting fixtures in the paint booth are designed according to the requirements of GB14444 93.

6. When heating and heating, there is enough exhaust gas overflow and fresh air replenishment in the room, and the exhaust gas overflow conforms to GB14443 93 "Safety Technical Regulations for Coating Drying Room".

7. Add over-temperature alarm function in the control system, once the heating temperature exceeds a certain set temperature, the system will automatically alarm.

Spraying exhaust gas is mainly the gas released from the process of painting and drying, which will damage the nervous system of the human body through breathing when discharged into the atmosphere. The damage plan mainly includes catalytic combustion unit (RCO), regenerative combustion unit (RTO) and low-temperature plasma.

If you are looking for waste gas treatment, I recommend finding a manufacturer with rich professional experience, because this can reduce your time and cost, and can give you a lot of suggestions on how to solve the waste gas and meet the emission standards.

At present, the state control environment is quite strict, and fines of hundreds of thousands or millions are imposed at every turn, so environmental issues are extremely important.

Personal suggestion: In this regard, I suggest you look for manufacturers in the Kunshan area, Aunason Environmental Protection Company focuses on waste gas treatment and provides one-stop solutions, you can consider it.

OK. 1. Acrylic paint.

Construction method: a variety of construction methods, but spraying is optimal, spraying and electrophoretic coating methods should not be used.

Paint matching: It can be matched with one-component volatile paints. As a topcoat, it can be applied to epoxy, polyurethane or alkene, rubber paints.

Construction skills: stir evenly, can use a mixed solvent of hydrocarbons and esters as a diluent, the film thickness is low, and it needs to be coated many times.

2. Polyurethane paint.

Construction method: a variety of construction methods, but spraying, brushing, roller coating is the most appropriate, not suitable for electrostatic and electrophoretic spraying.

Paint matching: can be used as primer, topcoat, when used as primer, the topcoat can choose a variety of organic paints, as a topcoat, the primer can only be epoxy or the same kind of paint.

Construction skills: two-component paint, add curing agent and stir evenly, the paint has a certain activation period and service life, and a thicker coating can be obtained by high-pressure airless spraying.

3. Organic polymer paint.

Construction method: a variety of construction methods, but spraying is optimal, and electrostatic and electrophoretic coating methods should not be used.

Paint matching: generally used alone, the primer can choose epoxy, the topcoat can choose alkyd, olekyd resin synthetic emulsion.

Construction skills: paint control drying temperature at the specified temperature, higher than the use temperature, do not rise sharply during drying, silicone insulating paint construction, to prevent the mixing of dust and foreign matter, can not be mixed with other resins, can add driers, with the use.

4. Chlorinated rubber paint.

Construction method: a variety of construction methods, but brushing, spraying, roller coating, optimal, should not use electrostatic and electrophoretic coating methods.

Paint matching: as a primer, the topcoat can choose one-component volatile paint or alkyd paint as the topcoat, and the primer is epoxy, polyurethane and other two-component paints.

Construction skills: fast drying, high temperature, high boiling point and aromatic solvents, long drying time, high pressure airless spraying can obtain higher film thickness.

In fact, it can be used even if you spray it. But if it is indoors, I recommend not to use it: because it has a bigger taste, is not environmentally friendly, and will affect my life!

You're talking about self-spraying, right? No problem, of course you can spray the wall, without thinking about cost and time!

Do you want to rest the wall, I also plan to do this, white self-spraying paint will not yellow.

Yes, but the cost is too high.

It is not recommended if it is partially repaired.

Large areas are not good. A small area is OK ...

Paint contains organic components such as formaldehyde, which are released into the air and are harmful to the human body. It often causes some allergic reactions in the respiratory tract, which generally improve after leaving.

The biggest harm is still controversial, and it may be related to the occurrence of certain malignant tumors! It is recommended not to be in such an environment for a long time, if you can't change the conditions due to work or other reasons, you can use some physical methods to protect yourself.

Paints contain toxic substances such as rosin, benzene and alcohols, which are quite harmful to the human body. If benzene vapor reaches a certain high concentration, it can cause death. Long-term exposure to benzene can cause chronic poisoning, resulting in leukopenia, thrombocytopenia, bone marrow hematopoietic dysfunction and other diseases.

When painting furniture, it contains toxic solvents that continue to volatilize, causing headaches, nausea, fatigue and abdominal pain, and long-term exposure can make people lose their appetite and cause chronic poisoning.

The harm of paint to the human body can occur not only through inhalation in the lungs, but also through absorption. The human body is in direct contact with paint, which can dissolve the fat in the paint, causing cracking and inflammation while also entering the human body.

Therefore, attention must be paid to the prevention and control of paint pollution. When painting, it is best to choose dry weather, open doors and windows, let the air flow smoothly, and reduce the concentration of solvents in the air in the room. Wear gloves and overalls when painting.

Immediately after painting, it should be cleaned ** and scrubbed with a mixture of fine yellow sand, sawn and butyl acetate.

In a word, dust-free workshop. There is a certain wind speed inside.

(1) The construction of the paint must be carried out within the indoor temperature required by the product. Different products have different temperature requirements, which can be found in the product packaging or manual.

2) Make sure that each process is dry before proceeding with the second process.

3) Use paints of the same substrate, do not mix different types of paints, to avoid adverse reactions.

4) During construction, safety protection measures should be taken, such as wearing masks.

5) Keep the room ventilated to prevent poisoning.

6) When using corrosive materials such as Tianna water, wear rubber gloves.

7) Do not smoke or use open flames on the construction site to prevent fire or **.

8) Avoid forced construction in the case of high humidity or high cold.

9) If there is a gap in the ceiling or wooden partition that needs to be covered, it can be treated with putty and then pasted with high-quality anti-crack tape; Cracks in the wall can be scraped open and filled with plaster, and then applied with high-quality anti-crack tape. The top coat is then painted.

10) Insist on buying paint from large shopping malls or experts to prevent counterfeiting, although ** will be slightly higher, but at least the quality will be guaranteed.

The air entering the paint booth must be carefully filtered to ensure that the air is free of dust.

The air flow in the paint booth must flow from the ceiling to the floor in the direction of gravity, and the air must be exhausted from the floor and filtered into cleaner air.

Ensure that the air in the paint booth is converted twice per minute, so the indoor air flow rate should be. The air flow rate is too large, the paint loss is too much, the coating condition is poor, and the air flow rate is too small, which affects the normal volatilization of the solvent.

It has good lighting conditions.

Make sure there is no negative pressure in the paint booth. This can be achieved by controlling the amount of air entering the booth and slightly more than the amount of air being exhausted.

The noise level in the paint booth is not allowed to exceed 85db.

Meets fire protection requirements.

If you want to paint the car perfectly, you must pay attention to these places, and the master will bring you masking skills.

The substance is toxic and has a certain impact on the body, and different brands of spray paint have different toxicity due to different ingredient content. Special attention should be paid to safety when using and avoiding inhalation and ** contact. Therefore, it is necessary to have protective equipment in place when painting, and at the same time limit the working time, and the work site must have good ventilation conditions.

Labor protection, ** and the respiratory system!

Pre-spraying treatment, spraying environment, thin material consistency.

1. Fresh milk or yogurt 2, sheep blood 3, brown sugar "Brown Sugar Water" are all good foods to kill the 'paint virus' in the body. Helps cleanse the blood of toxins.

A glass of fresh milk or a cup of pasteurized yogurt per day can precipitate the isolight salts contained in the curing agent.
