The most worthy of our attention in the decoration is paint. In recent years, hundreds of paints have appeared on the market, and their prices are also high or low. Therefore, before the renovation, we must understand the variety of paint, so as to better dress up your home.

Latex paint consists mainly of water, pigments, emulsions, fillers and various additives. These raw materials are non-toxic and may contain mainly organic mercury in the film-forming agent ethylene glycol and fungicide.
Variety of paint used in home decoration:
(1) Wood lacquer
Varnish:
Nitro varnish is a kind of transparent paint made of nitrocellulose, alkyd resin, plasticizer and organic solvent. It is a kind of volatile paint, with quick drying and soft gloss.
Nitro varnish is divided into light, semi-matt and matte, which can be selected according to the need.
Nitro-lacquer also has its disadvantages: high wet weather is easy to whiten, low fullness, and low hardness.
Hand sweep paint:
Nitro lacquer is also a nitrocellulose paint. It is a non-transparent paint made of nitrocellulose, various synthetic resins, pigments and organic solvents.
This paint is specially formulated for artificial construction and features quick drying.
The main auxiliaries for lacquer:
That day water. It is a colorless, transparent liquid with a banana odor that is a mixture of organic solvents such as esters, alcohols, benzenes, and ketones. It mainly initiates nitrocellulose lacquer and cures.
White water. Also known as anti-white water, the scientific name is ethylene glycol monobutyl ether.
In the wet weather construction, the film will have a whitening phenomenon. Adding 10%-15% of the diluent to the nitromagnetized white water can be eliminated.
Polyester paint:
It is a thick paint made of polyester resin as the main film forming material.
The paint film of polyester paint is full and the layer is hard. Polyester paints also have varnish varieties called polyester varnish.
Polyester paints need to be cured during the construction process. The amount of these curing agents accounts for one-third of the total paint content.
These hardeners are also called hardeners and their main component is TDI (toluene diisocyanate).
These TDIs that are in a free state will turn yellow, which will not only make changes to the furniture, but will also cause yellowing of adjacent walls. This is a major drawback of polyester paints.
A yellowing-resistant polyester paint has appeared on the market at present, but it can only achieve "yellowing resistance." It cannot completely prevent yellowing.
In addition, free TDI beyond the standard can also cause harm to humans.
Polyurethane paint:
That is, polyurethane paint. Its film is tough, full gloss, strong adhesion, water resistance, wear resistance, corrosion resistance, is widely used in advanced wood furniture, but also for the metal surface.
The main disadvantages are the blistering of the tide and the powdered film. Like polyester paint, there is also the problem of yellowing.
The varnish type of polyurethane paint is called polyurethane varnish.
(2) Interior wall paint
Interior wall paint is mainly divided into water-soluble paint and latex paint.
General renovations use latex paint. Latex paints are emulsion paints. According to the different substrates, they are divided into polyester acid vinyl emulsion and acrylic emulsion.
The latex paint is made of water as the diluent, which is a kind of lacquer that is easy to use, safe, washable, and has good air permeability. Different colors can be formulated according to different color schemes.
Latex paint consists mainly of water, pigments, emulsions, fillers and various additives. These raw materials are non-toxic and may contain mainly organic mercury in the film-forming agent ethylene glycol and fungicide.
At present, the so-called “latex paint†that contains a large amount of formaldehyde on the market is actually a water-soluble paint, not a latex paint. Some unscrupulous manufacturers use inferior water-soluble paints to fake latex paints.
Therefore, choosing the right goods and maintaining ventilation is an effective way to prevent pollution.
(3) Exterior wall paint
The basic performance of exterior latex paint is similar to that of interior latex paint, but the paint film is harder and more resistant to water.
Exterior latex paints are generally used on exterior walls and can also be used in high humidity areas such as toilets.
Of course, exterior latex paints can be used internally, but do not use exterior latex paints for external use.
(4) fireproof paint
Fire-retardant paint is a kind of flame-retardant paint made of film-forming agent, flame retardant, foaming agent and other materials.
Due to the current heavy use of flammable materials such as wood and fabrics, fire protection is already a worthy issue.

Ground Screw driver,for installing ground screw, mainly applied for mounting garden fences,traffic guidancs,advertising boards,carports,flagpoles,wooden houses,Constructional Industry and etc. Electric tool max. power consumption is 1800W-5000W and workers can install more effective and saving time. Manual tool also widely used because of easy installation.
Driven piling is well known for the following advantages for construction issues –
Relatively small and lightweight equipment is required
Relatively small cross-section and high strength helps penetration in firm soil
Require minimal site preparation
Spoil free means minimal cost for disposal of site debris
Cost-effectiveness where many piles are required
