The cooling curtain must be used in conjunction with the fan to allow ventilation and achieve the cooling effect. When the outdoor dry hot air passes through the wet curtain, it will release a lot of water vapor, absorb the heat in the air, and make the air moist and cool. This principle is air cooling. Let us give a vivid example: for example, the wind in the lake is cool in summer, and the wind in the desert is hot.
Good curtain paper generally adopts anticorrosive resin and raw wood pulp absorbent kraft paper for high temperature melting and arch extrusion to form a new material with strong anticorrosive properties, especially for water immersion and waterproofing.
Inferior wet curtains are generally made of recycled paper, the fiber length is not enough, and the water absorption is not good enough;
Cooling wet curtain processing procedures: spraying, drying, curing, molding, single curing (anti-corrosion resin arch extrusion, not easy to lose, increase life), bonding, molding, cutting, grinding and other processes.
1.According to the national standard document, the wet curtain bonding standard can be compared with the data parameters
2.Wet curtain service life:7-8Annual normal service life
3. [strength]: Mainly used for strength test, generally10 * 250 pxWet curtain paper (strength about65 kg)
4. [Absorb water]: Water absorbs water from bottom to top.5Natural climb height in minutes7Cm, good water absorption
5. [Corrugated height]:7Corrugated height angle mm45 * 45Degree) The lower the corrugated height value, the better the paper quality. (But the lower the energy consumption and the greater the negative pressure, the user should have a more practical choice.)
6.The general number is7090,7Corrugated height,90For paper,7090It is used for cooling damp curtain used in greenhouse. (The higher the ripple, the lower the production level and the lower the price)
