Material: Wood lacquer

Commonly used wood lacquer lacquer, polyurethane paint and waterborne wood lacquer three.

Comparison of main varieties of wood paint

Nitrocellulose paint (NC): Good decorative effect; fast drying speed; relatively low solid content in repair; poor durability, gloss, and color retention; poor environmental protection.

Polyurethane paint (PE): The paint film is plump and thick, with good gloss and transparency. It is hard and wearable, and it has strong adhesion. The paint film is damaged and difficult to repair; the drying speed is slower; the coating film tends to turn yellow.

Waterborne wood lacquer (W): good environmental protection; no yellowing, excellent water resistance, no burning; rust, high temperature part of the hardness of water-based paint is not high; construction environment requirements are relatively high.

Wood lacquer construction is a very precise and meticulous task and requires suitable environmental conditions. Temperature, humidity, light, ventilation, and hygiene are all in line with one

Demand can only make a good paint finish.

Temperature: It is best performed at room temperature (15-30?°C). If the temperature is too low, the paint film will become slow. If the temperature is too high (more than 35?°C), the brushing performance will be adversely affected.

Humidity: Avoid humid air, which is detrimental to most paints, especially lacquer, polyurethane paint, etc. Construction in wet and rainy weather can cause whitening or slow drying.

Light: Adequate light helps to see the varnish, identify whether the coating is uniform, and avoid brushing or sagging in time. Therefore, it should be selected for construction in a well-lit room.

Ventilation: Ventilation equipment should be provided at the construction site to maintain a proper amount of fresh air circulation. This will not only be beneficial to the health of the constructors, but also be conducive to film formation and reduce the risk of fire. However, the speed of air circulation must not be too fast so as not to affect the quality of the coating.

Hygiene: The construction environment must be kept clean. The dust and debris generated during the construction process should be immediately removed. Otherwise, the final effect of the paint film will be affected. The clean construction environment is especially important when applying floor paint.

Product introduction
HHCMS-240 type Carbon Molecular Sieve
HHCMS-240 is a new kind of non-polar adsorbent. It is designed to extract nitrogen-rich gas from the air. It is suitable for separating nitrogen from the air.
The most notable features of the carbon molecular sieve are high gas-producing efficiency and low waste, especially nitrogen with a purity higher than 99.9%.

It is widely used in large air separation and sheet making equipment, and the application field covers the high-end aspects such as the storage and transportation of crude oil in yibi ships.

Pay attention to
1. The nitrogen production equipment can reduce the adsorption temperature to better show its excellent nitrogen production performance under conditions;
2. Pay attention to low temperature drying and seal preservation during storage;
