It is mainly used to cover the surface of national musical instruments.
Add plastics such as curing agents. It is a thermosetting plastic. It has the characteristics of fast curing, no release of volatiles, low molding shrinkage, dimensional stability and excellent electrical properties. Can be used as electrical component encapsulation and reinforced plastic.
Alkyd varnish brushing furniture steps
The surface of wood furniture should be handled cleanly without any foreign matter and the surface is smooth and flat. If the furniture is to be refurbished, the original paint must be removed to avoid chemical reaction with the alkyd varnish, and the paint can be removed by smearing the paint on the surface.
The alkyd varnish and alkyd thinner are mixed well, stir evenly with a soft brush dipped in a little paint to brush the brush is best washed, after the dry hair will be removed and reused. The brush should not be immersed in paint more than one third of the length of the hair when used. Then the first obliquely followed by straight, first up and down, first left and then right, vertical and horizontal application to form a uniform thin layer, this operation is light and fast appropriate.
After painting, the thinner is used to clean the paint brush, and the furniture is placed in a place where bumping is avoided. The solvent is volatilized. After the paint is completely dried, the paint film becomes hard and the furniture can be used indoors.
Alkyd varnish price issue
Now that the paint market is relatively open, it is not like dark water flowing like building materials. After all, paints are chemically synthesized, have high scientific and technological content, are not easily monopolized, and are more vulnerable to external factors than the timber market where trees are used as raw materials for production. Impact, less adulterated, but there are price differences.
What is the price of brush alkyd varnish?
Paints are sold at retailers in separate buckets and the price will be slightly higher. If you want to save money, you can order online directly as a paint factory or a second-tier operator (not recommended because the MOQ is relatively large). Of course the paint is also To sub-model and capacity, different prices per barrel price is not the same. Paint factory price is generally: 15-499 kg is 18, 500-999 kg is 18, more than 1000 kg is 17.5. The general price is: 1-9 barrels are around 130, 10-49 barrels are 120, and over 50 barrels is 108.
Of course, everyone also knows that there are many kinds of paint bucket packaging capacity (1L/4L/12L/15L/17L/18L/19L/20L, etc.), oily general 4L is about 4KG, 18L is about 17KG, water-based big 5L6KG/20L20KG , Do not rule out that some manufacturers a higher asking price is due to a large number of liters. For example, a barrel of 5L oil paint price 72 per barrel, a barrel of 12L paint price 206, the former 14.4 yuan per liter, the latter per liter 17.1 yuan, it seems that it seems to be similar. But now the paint market shipments are not uniform, some price by barrel, some by weight, plus the fundamental difference between oily and water-based paint production process, causing many consumers to complete Do not understand why the same coating, ranging from tens to hundreds of barrels per kilogram.
Buy paint must brush, the specific price of the brush should be calculated according to the square meter construction method. 1, direct brush coating general material price is about 10 yuan; 2. wall repair brush material general material price is about 15 yuan; 3, wall The surface of putty putty process general materials price of 29 yuan. The more regular is equal to the statutory fees and taxes + part of the sub-item price, part of the item price is equal to labor costs + mechanical fees + material fees, which is the project cost of professional knowledge If you ask the decoration company to brush it, they will count it on this basis. If you ask the worker's master, you must negotiate yourself.
In short, although there is no big change in the price of the paint market, but because the business home is completely inconsistent with the weight and capacity of the goods, the delivery price is based on the way they are accustomed to, for example, how much money he said for a bucket. , How much is a kilogram of money, these consumers should pay more attention to their own, how much they need to count themselves in advance, and then according to actual needs is to buy barrels or kilograms to buy, so that the interests and needs of the utmost.
