First of all, we know that suspended QF-13A sulfuryl fluoride fumigant and suspended ultra-fine dry powder are both fire extinguishing systems, but in fact they belong to two different fire extinguishing systems. Heptafluoropropane belongs to gas fire extinguishing, and ultra-fine dry powder belongs to dry powder fire extinguishing. However, since both have a suspension type in use, today, we will compare the two.

The first is the suspended heptafluoropropane. The suspended heptafluoropropane is an application form of heptafluoropropane fire extinguishing agent. Its characteristic is that it has the excellent fire extinguishing characteristics of heptafluoropropane, and it is small, light and easy to install. It is divided into: temperature control, electric control, and electric control. Three control spray modes with dual temperature control. It is especially suitable for small places or the protection area of ​​a small area separately. At the same time, heptafluoropropane also has the advantages of no damage to the equipment, good electrical insulation, and long spray distance, and only within the design concentration, the suspended heptafluoropropane will not cause harm to the human body Harm (the low design concentration of heptafluoropropane is generally 7%, and the human body can be exposed to the harmless concentration of heptafluoropropane is 9%), which relies on the great non-conductivity of heptafluoropropane, so it is especially suitable for use in computer rooms and computer rooms, or Server rooms and other places. When the heptafluoropropane reaches a certain concentration in the protection zone, it also has the effect of suppressing the explosion.

As for suspended ultra-fine dry powder, ultra-fine dry powder is usually divided into BC type dry powder or ABC type dry powder, which are weakly alkaline or weakly acidic. At the same time, ultra-fine dry powder has smaller particles than ordinary dry powder, generally one-tenth of the size. The suspension type ultra-fine dry powder has two forms: storage pressure and non-storage pressure, and is used in different scenarios. At the same time, the suspension type ultra-fine dry powder has stronger fire extinguishing efficiency and more suitable environment. Wide, the fire extinguishing efficiency is ten times faster than heptafluoropropane, and the cost is lower than gas fire extinguishing, but the disadvantage is also great, that is, the degree of pollution is large, the falling dust is difficult to clean, and the time to float in the air is limited. When it settles, it will not move, and it is very taboo to have obstructions. It is difficult to surpass the past and will affect the fire extinguishing efficiency. The important thing is that ultra-fine dry powder cannot be used in scenes where people are often infested and there are many electronic devices. The first person breathes into the body It is harmful to the body, and the second electronic device Z is afraid of dust and dust, and is prone to malfunction and even protection.

And this is the difference between Fluorinated Solvent Manufacturers suspended heptafluoropropane and suspended ultra-fine dry powder. The former is more dominant in computer rooms, server stations or protective areas with many electronic equipment. Suspended ultra-fine dry powder is more suitable for use in unmanned places. , Especially in the urban underground pipe gallery will play a greater role.
