Embodiment Construction

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0022] In order to judge whether there is a correlation between the rust of the stainless steel coil and the fire of the PVC material, the following steps are taken:

[0023] Step 1) First check the environment between the fire scene and the stainless steel coil storage site, and judge whether the fire combustion residue can fall to the stainless steel coil. When the fire combustion residue cannot fall to the stainless steel coil, it means that the storage airtightness is good , will not cause contact with external fire products, so the ...

Abstract

The invention discloses a detection method of the relevancy between rustiness of a stainless steel coil and ignition of a PVC material. The method comprises the following steps: 1) detecting the environment between a fire scene and a stainless steel coil storage scene, and judging whether fire combustion residue can float to the stainless steel coil; 2) opening the stainless steel coil, and detecting whether the rust degrees of the inner coil and the outer coil of the stainless steel coil are the same; 3) observing the rust trace on the surface of the stainless steel coil, and observing whether an adhered foreign matter exists on the surface; 4) performing element detection on the rust surface of the stainless steel coil, and determining whether chlorine element exists in a rust spot; 5) determining the fact that rust of the stainless steel coil is related to the ignition of the PVC material when the chlorine element exists in the rust spot, and determining the fact that rust of the stainless steel coil is not related to the ignition of the PVC material when the chlorine element does not exist in the rust spot. The method is simple in operation and reliable in results, and can rapidly obtain a conclusion whether rust of the stainless steel coil is related to a PVC fire.

Description

technical field [0001] The invention relates to the identification field, in particular to a method for detecting the correlation between rusting of stainless steel coils and fires of PVC materials. Background technique [0002] 304 stainless steel is the most widely used chromium-nickel stainless steel. As a widely used steel, it has good corrosion resistance, heat resistance, good low temperature strength and mechanical properties; it has good hot workability such as stamping and bending, and has no Heat treatment hardening phenomenon (use temperature -196 ° C ~ 800 ° C), with good processability and weldability. Widely used in plate heat exchangers, bellows, household goods, auto parts, medical appliances, building materials, chemistry, food industry, agriculture, ship parts, Xiaomi mobile phones, etc. [0003] The stainless steel plate has a smooth surface, high plasticity, toughness and mechanical strength, and is resistant to corrosion by acids, alkaline gases, soluti...
