Abstract
GMG explosion hardening explosive relates to the technical field of explosives, and in particular relates to a special explosive for high-manganese steel pieces explosion hardening treatment. The invention mainly addresses the problem that the effect of a mechanical method for high manganese steel piece hardening is not ideal. The GMG explosion hardening explosive comprises, by weight, 40-80% of a main explosive cyclonite, 10-30% of a high-molecular material and 10-30% of a plasticizer. The high-molecular material is a collodion; the plasticizer is acetyl tributyl citrate; the plasticizer is triacetin; the plasticizer is tributyl acetyl citrate and triglyceride triacetate in the weight ratio of 1:1. A density additive accounts for 0.1% of the total weight of cyclonite and the high-molecular material. The explosive has the advantage of good hardening effect on high-manganese steel pieces after explosion.
Description
Technical field:
The present invention relates to explosive technical field, specifically relate in the special dynamite during explosion hardening process of high mangaenese steel part.
Background technology:
In order to improve the surface strength of high mangaenese steel part, strengthen its wear resisting property etc., so need carry out hardening treatment to its surface, the mechanical means that adopts carries out hardening treatment to high mangaenese steel part more at present, and its weak point is that efficiency is low, and the effect of sclerosis is undesirable.
Summary of the invention:
Technical problem to be solved by this invention is to provide a kind of GMG explosion hardening explosive of plasticity sheet, and it utilizes the shock action produced surrounding medium during explosive charge, and realize the object to high mangaenese steel part Surface hardening treatment, hardening effect is good, and sclerosis efficiency is high.
For achieving the above object, the present invention adopts following technical scheme: it comprises main body explosive Cyclotrimethylene trinitramine, macromolecular material, softening agent.
Wherein each raw material accounts for the per-cent of gross weight and is: Cyclotrimethylene trinitramine accounts for 40%-80%; Macromolecular material accounts for 10%-30%; Softening agent accounts for 10%-30%.
Described macromolecular material is collodion;
Described softening agent can be Tributyl O-acetylcitrate;
Described softening agent can be three acetic acid Witepsol W-S 55s;
Described softening agent can be Tributyl O-acetylcitrate and three acetic acid Witepsol W-S 55s, and the weight ratio of Tributyl O-acetylcitrate and three acetic acid Witepsol W-S 55s is 1:1.
For the ease of adjustment explosive density, ensure the elasticity of explosive, also can add the density additive accounting for Cyclotrimethylene trinitramine and macromolecular material and softening agent gross weight 0.1%.
Production method: above-mentioned each raw material is joined in mixing tank, stirs, then make sheet by pelleter.
Described Cyclotrimethylene trinitramine, collodion, Tributyl O-acetylcitrate, three acetic acid Witepsol W-S 55s, density additive all can be buied from market.
Advantage of the present invention is: during use, sheet explosive is placed in high mangaenese steel part surface, fired charge.Because the explosion velocity of explosive is higher, brisance is large, and detonation is stablized, and it is good, flexible to lay performance, can be cut into different shape as required, therefore easy to use.
The advantages such as after the explosion hardening of high mangaenese steel part, the hardness of high mangaenese steel part increases, life, better than adopting other mechanical means to have hardening effect, convenient.
Three acetic acid Witepsol W-S 55s, have good consistency with collodion, and make explosive density even after adding density additive, plasticity is good, and is easy to film-making.
Tributyl O-acetylcitrate, nontoxic, volatility is little, good with collodion consistency, water-fast, resistance to low temperature is good.
Embodiment:
