The fireproof board adopts calcium and silicon as main materials, and is mixed with a certain proportion of lightweight aggregates, adhesives, and chemical additives. The decorative sheet made of autoclave is currently more and more used as a new type of material. The following small series to introduce fire sheet characteristics and classification of fire protection board.
Fire board features
1. Thermal Insulation: The thermal insulation and thermal insulation performance of this fireproof sheet is six times that of fireproof sheet glass and ten times that of ordinary concrete.
2, fire-retardant flame retardant: concrete is inorganic, will not burn, will not produce harmful gases at high temperatures; In addition, the small thermal conductivity of concrete, making the slow heat migration, can effectively resist fire, protect the structure from the fire.
3, processing convenience: can be sawed, millable, nailed, easier to reflect the design intent.
4, sound absorption sound: a good sound insulation and sound absorption.
5, good durability: good durability, no aging problems, long service life.
6, green environmental protection: When used, there will be no radioactive materials and harmful gases, independent of the micro-bubbles, can make gas concrete products have a certain impermeability, can prevent the penetration of water and gas.
Fire board classification
1, mineral wool board, glass wool board
This kind of sheet has good high temperature resistance and light texture, but its strength is poor, and short fibers can cause respiratory harm to the human body.
2, cement board
The strength of the cement board is high, but its fire resistance is relatively poor, and it is easy to burst and perforate in the fire field, losing its protective function and restricting its application.
3, perlite plate, floating bead plate, slate stone plate
This kind of plate has the characteristics of high strength, good toughness, fireproof and heat insulation, and convenient construction. These plates are mainly used for non-load-bearing parts such as toilets, kitchens and communication pipes.
4, fireproof gypsum board
This kind of sheet has good fire resistance and can be used as partitions, ceilings and roof panels. In use, light weight, can reduce the building load, easy processing, easy construction, good decorative performance, poor bending resistance.
5, calcium silicate fiber board
This kind of sheet is mainly used for fire protection materials of ceilings, partition walls, steel columns and steel beams, but the strength and bending properties of such fireproof sheets need to be improved.
Edit Summary: On fire sheet characteristics and fire sheet classification introduced here, and we want to help, want to learn more knowledge can follow this website information.

Warnings:
1.lndoor use only.
2.To avoid being damaged,do not use water or drip irrigation while using.
3.Sunshine lighting time should be 12-18 hours.
4.While irradiating the plants,the height of led grow lamp is not less than 10 inches,
low height will cause the destruction of plants.
5.Highly hang the lamp will weaken the energy and affect the growth cycle of the
plants, so the lamp should not be hung too high.
6.While taking care of the plants, please spray the leaves and branches 2-3 times everyday,
to ensure the the plants do not wrinkle a wither, and have no phenomenon of few fruit, and
hard pericarp.
