Description
Technical field
The present invention relates to a kind of extinguishing chemical, particularly a kind of extinguishing chemical of modified grammite.
Background technology
Liquid foam extinguishing chemical is gone out currently used for the main of the non-water soluble substance fire such as oil and oil product of putting out a fire to save life and property
Fiery agent, there is remarkable mobility in fuel surface, by the lightweight feature and buffer action of foam, quickly control the intensity of a fire, have
Effect stamps out a fire, however by the fire foam that gas-liquid two-phase is formed when scene of fire is acted on by thermal shock stability
Relatively low, anti-resume combustion ability is poor, bad to the effect of generation again of suppression fire.If it is intended to reach more satisfactory anti-multiple
Fuel efficiency fruit, then substantial amounts of fire foam is needed, this means that the demand increase of water, as a result can cause substantial amounts of contaminant water
Discharge, have a strong impact on the environment of surrounding.
To solve the problems, such as liquid foam extinguishing chemical stability difference, consider the solid particle in liquid foam, grind early stage
Study carefully the stability for showing that spherical modified expanded glass bead particle can improve liquid foam extinguishing chemical to a certain extent, and
Effectively extend fire resistanttime, but expanded and vitrified small ball is hollow structure, it is frangible, and complex manufacturing, cost is high, in liquid
Measured in fire foam larger.Simultaneously as be expanded and vitrified small ball be chondritic, cause the fluid-carrying capability of foam
It is relatively low, therefore drainage time is shorter, foam separation layer is unstable, and anti-resume combustion effect is undesirable.
The content of the invention
The present application aims to overcome that the shortcomings that existing two-phase fire foam burn resistance difference, and provides a kind of tool
There are stronger water-retaining property, the extinguishing chemical of the modified grammite of adhesiveness, compactness and higher anti-resume combustion.
In order to complete present invention purpose, the application uses following technical scheme：
A kind of extinguishing chemical of modified grammite of the present invention, it includes：The component A of 60~100 mass parts, 2~8 mass parts
Component B and 3~12 mass parts component C, wherein：Component A is fibrous wollastonite, and component B is non-ion fluorin carbon surface

After~12 hours, filter, finally fibrous wollastonite is dried 48 hours at a temperature of 60 DEG C or so, obtained by surface
The fibrous wollastonite of modification, the fibre length of the fibrous wollastonite by surface modification treatment are micro- for 85~460
Rice, fiber width are 8.5~30 microns, and the ratio of fibre length and fiber width is 10~30:1, in use, by above-mentioned process
The fibrous wollastonite and component B of surface modification treatment are with water with 15~40:100 ratio is mixed；
A kind of extinguishing chemical of modified grammite of the present invention, wherein：The described fibrous silicon by surface modification treatment
The fibre length of lime stone and the ratio of fiber width are 18:1；
A kind of extinguishing chemical of modified grammite of the present invention, wherein：The extinguishing chemical of the modified grammite includes：65 mass
The fibrous wollastonite by surface modification treatment of part, the non-ion fluorin carbon surface active agent and 1.5 mass of 0.5 mass parts
The hc-surfactant of part；
A kind of extinguishing chemical of modified grammite of the present invention, wherein：The extinguishing chemical of the modified grammite includes：100 matter
Measure the fibrous wollastonite by surface modification treatment of part, the non-ion fluorin carbon surface active agent and 2.5 matter of 0.8 mass parts
Measure the hc-surfactant of part；
A kind of extinguishing chemical of modified grammite of the present invention, wherein：When in use, by the fiber Jing Guo surface modification treatment
Shape wollastonite and component B and water are with 30:100 ratio is mixed.
A kind of extinguishing chemical of modified grammite of the application is mainly used in putting out a fire to save life and property for colliery and petroleum product fire, after foaming
The foam of formation, good water-retaining property, stability is high, and volume significantly increases, and can quickly be formed and is completely covered in pasta, and in oil
Face forms fine and close firm separation layer, effectively separates oil product and the oxygen in air, and effectively blocking radiant heat.With
Foam is constantly squeezed into, and foam coverage scope constantly expands, and the intensity of a fire is extinguished area and gradually increased, until burning things which may cause a fire disaster all extinguishes；To covering
The fuel oil of lid has the effect of cooling, radiating and cooling, even if after bubbles burst, still can form the covering of densification on the surface of oil
Layer, effectively blocking radiant heat, anti-resume combustion are very strong.Raw material are rich in minerals simultaneously, and simple production process, cost is low, fire
Small it can reach more satisfactory anti-multiple using a kind of extinguishing chemical demand of modified grammite of the application in calamity rescue operations
Fuel efficiency fruit, caused pollutant effluents is less, is advantageous to environmental protection.
