How to carry out fire control acceptance of constant temperature and humidity test chamber

Constant temperature and humidity test chamber can simulate high temperature, low temperature, humid heat, constant temperature and humidity and other environmental conditions, through the set conditions can quickly cycle to test whether the instrumentation products have high temperature resistance, low temperature resistance, humid heat resistance and other performance, reduce failure, improve quality
.

As a large and medium-sized natural environment experimental equipment, the safety factor of the constant temperature and humidity test chamber is particularly important, and it is also the primary condition
for commenting on the quality of this machine and equipment.

Often, people will see news reports of tragic information such as warehouse fires and production workshop fires, and in many cases simple warehouses are the key cause of
this disaster.

In order to reduce the risk of fire accidents to a very low level, we must first do a good job in the content of the article from the raw materials, which is also the main stage
of fire engineering acceptance.

According to the standard of "Classification of Combustion Performance of Building Materials" in China, the wall materials selected for the constant temperature and humidity test chamber rarely meet the requirements of
B1 level.

Therefore, the raw materials for the external wall insulation of the constant temperature and humidity test chamber produced and manufactured are generally made of polyurethane polyurethane foam
with high flame retardant grade.

The traditional selection of trichloroethyl phosphate (TCEP), tri(2,3 dibromopropyl) melamine (TBC), dimethyl hydroxyphosphonate (DMMP) and other organic chemical halogen-free flame retardants containing phosphorus and halogen, although it can increase the flame retardant level of PU hard bubbles to about 26, but there is still a certain difference
with the provisions of safety and fire protection on engineering building thermal insulation materials.

High flame retardant grade rigid polyurethane polyurethane foam is applied by mixing solid halogen-free flame retardants and liquid halogen-free flame retardants to produce a high flame retardant rigid polyurethane material plastic foam
with a flame retardant rating of more than 30.

At the level of constant temperature and humidity test box jewelry, in order to achieve the acceptance specification of fire protection engineering, lighting fixtures must be waterproof and explosion-proof types, waterproof grade considers IP65, explosion-proof grade in line with GB3836-2000 "explosive gas environment electrical equipment" specification
.

Back to the outside world, the surrounding area of the laboratory must avoid fire extinguishers, part of the electrical equipment needs to be installed with charge and discharge fire safety signs, and the actual operation area and safety area must be planned with warning tape
.

This kind of fire engineering acceptance is an important key point
