Description
Technical Field
The invention relates to the technical field of toughened glass breaking and disassembling, in particular to a toughened glass breaking and disassembling method based on a self-propagating technology.
Background
The toughened glass is obtained by cutting common annealed glass into required dimensions, heating to about 700 ℃ close to a softening point, and then rapidly and uniformly cooling, wherein the glass with the thickness of 5-6mm is heated at a high temperature of 700 ℃ for about 240 seconds, and the temperature is reduced for about 150 seconds. The glass with the thickness of 8-10mm is heated at the high temperature of 700 ℃ for about 500 seconds, and the temperature is reduced for about 300 seconds. In short, the time for heating and cooling is selected to be different according to the thickness of the glass. After the tempering treatment, the surface of the glass forms uniform compressive stress, while the inside forms tensile stress, so that the bending resistance and impact resistance of the glass are improved, and the strength of the glass is about more than four times that of common annealed glass.
Since the tempered glass is broken, the broken pieces are broken into uniform small particles and have no sharp corners like a general glass knife, so that the tempered glass is widely used in automobiles, interior decorations, and windows opened to the outside at high floors, which are called safety glass. However, tempered glass brings some problems while bringing safety and convenience to us. For example, when an accident occurs, people often need to quickly destroy doors and windows made of tempered glass to escape and rescue; when the police execute the task, the gangster is required to be broken and disassembled quickly. The strength of the toughened glass is far greater than that of common glass, so that the breaking and disassembling difficulty is great, and the conventional breaking and disassembling method comprises the following steps: 1. the hammer is violently hammered using a safety hammer or the like. The method has high strength requirements on operators, can not be completed by common people, and can not take a long time even if the operators break the steel plate successfully, and can not play an emergency role; 2. the glass breaker for breaking the toughened glass in a blasting manner has high self-explosion power when in use, and is easy to hurt people; secondly, when the toughened glass is blasted, a large number of high-speed flying pieces can fly out of the glass, and people are easily injured as well; thirdly, the blasting products belong to national high-safety control products, are limited to be used in public places, and are not beneficial to popularization and application.
In recent years, in order to overcome this difficulty, a great deal of research has been conducted by the scholars. Patent application number 201120416175.2 and patent application number 201510041620.4 disclose two tempered glass breaking devices, and both inventions utilize high-pressure gas to drive a high-hardness hammer to impact the surface of glass and crush the glass. The breaking and disassembling principle is basically the same as that of the safety hammer, but the limitation of the safety hammer to the physical ability of an operator is overcome by replacing manpower with high-pressure gas. However, the principle of high pressure gas generation is similar to explosion, with a greater risk. In addition, as the strength of the toughened glass is large, a large force is required for beating by using a mechanical means, the device is not exploded on the premise of generating the atmospheric pressure, which means that the wall thickness, the weight and the impact force during working of the device are large, the operation difficulty is not small, and the device is disposable equipment, and a plurality of devices are required to be carried for ensuring success when executing a task, so that the limit in practical application is increased; the patent application number 201410597066.3 discloses a toughened glass crushing device, which crushes toughened glass by utilizing static pressure generated by a mechanical transmission structure, but the device needs to be installed with the toughened glass in advance, and has a narrow application range; patent application No. 201410823156.X discloses a toughened glass cutting method, but the method needs to be operated at both sides of glass simultaneously, and the whole process needs several ten minutes, so that the method is suitable for precision cutting in factories and is not suitable for emergency breaking and dismantling in rescue. Patent application No. 201510053001.7 discloses a tempered glass cutter which cuts tempered glass by heating a blade by electric energy and using a high Wen Daofeng. However, since the softening temperature of glass is around 700 ℃, such a high temperature requires an external power source to supply electric power, and the battery cannot meet the requirement. In emergency activities such as rescue and relief work, anti-terrorism and obstacle clearance, external energy sources are difficult to obtain, for example: high-speed roads, fire sites and gangster controlled buildings. The application is greatly limited.
Based on the defects of the technology, the invention provides the toughened glass emergency breaking and disassembling method which has the advantages of simple equipment, low operation difficulty, low cost, high speed and strong environmental adaptability and does not need additional energy.
Disclosure of Invention
The invention aims to solve the technical problems and provide a toughened glass breaking and disassembling method based on a self-propagating technology, which has the advantages of low operation difficulty, low cost, high speed and strong environmental adaptability, and can break and disassemble the toughened glass without additional energy sources.
In order to solve the problems, the invention adopts the following technical scheme:
a toughened glass breaking and disassembling method based on a self-propagating technology comprises the following steps:
(1) Cleaning attachments on the surface of the toughened glass, and selecting one point on the toughened glass as a fixed point;
(2) Igniting a cartridge A, igniting fixed points for 5-10s, wherein the preparation raw materials of the cartridge A comprise oxidant, reducing agent and diluent, adjusting the proportion of the oxidant, the reducing agent and the diluent to ensure that the adiabatic reaction temperature of the cartridge A is 2100k-2500k so as to cope with glass with different thicknesses, uniformly mixing medicinal powder, loading into a cartridge, and packaging the cartridge by using the ignition medicinal powder;
(3) Igniting the cartridge B, taking the fixed point as the center, and horizontally shifting up and down and left and right for 15-45s; 3-15s after the completion of the baking, the toughened glass automatically and vertically collapses, the preparation raw materials of the cartridge B comprise an oxidant, a reducing agent and a diluent, the adiabatic reaction temperature of the cartridge B is 2500k-2900k to cope with the glass with different thickness by adjusting the proportion of the oxidant, the reducing agent and the diluent, the cartridge B is filled into the cartridge after uniformly mixing the medicinal powder, and the cartridge is packaged by the ignition medicine.
Further, the preparation raw materials of the cartridge A specifically comprise: al, mnO 2 、CaSO 4 、CaF 2 The method comprises the steps of carrying out a first treatment on the surface of the The preparation raw materials of the cartridge B are specifically as follows: al, cuO, KNO 3 、CaF 2 。
Further, the flame of the cartridge A is 1-2cm from the surface of the tempered glass.
Further, the flame of the cartridge B is 1-2cm from the surface of the tempered glass.
Further, the speed of the translation and the firing in the step (3) is 10-20cm/s.
The invention utilizes the heat generated by chemical reaction to destroy the stress structure of the toughened glass, thereby achieving the breaking and disassembling effect. After the toughened glass is processed, the two sides of the glass are in a compressive stress state, and the middle part of the glass is in a tensile stress state. The cartridge A is used for destroying the stress structure in a small range, so that one side is heated violently, the compressive stress is relaxed, the glass is still in a compressive stress state for the other time due to slow heat transfer, and the toughened glass is bent under the left and right forces. Cartridge B is used to spread local stress failure to a slightly larger extent, resulting in a slightly larger extent of stress failure. After firing of the cartridge A and baking of the cartridge B, the stress state of the heated area and other areas are greatly different, and the glass is cracked and broken under the action of uneven stress.
The oxidant and the reducing agent have the functions of generating heat through chemical reaction, and the diluent has the function of absorbing part of the heat of reaction, so that the reaction is gentle and slow, and the hand-held operation is convenient.
Compared with the prior art, the toughened glass breaking and disassembling method based on the self-propagating technology has the outstanding characteristics and excellent effects that:
1. the method and the equipment are simple: the invention utilizes chemical reaction to complete the breaking and disassembling, does not need any auxiliary equipment, only needs to store a certain amount of medicine powder A and medicine powder B in advance, and can fill the medicine cartridges A and B with different lengths according to the thickness of glass temporarily.
2. The breaking and disassembling speed is high: the whole process is completed within 70S, and the speed is far faster than that of the existing breaking and disassembling technology.
3. The safety controllability is good: the toughened glass naturally collapses under the action of stress, and the toughened glass vertically falls down when collapsing, does not generate any horizontal splashing, and has high safety.
4. The environment adaptability is strong: the method does not need any external energy source, can perform the breaking and disassembling operation in a severe environment, and is not limited by the environment.
5. The repeatability is strong: the breaking and tearing method can break and tear the toughened glass with the thickness of 6mm, 8mm, 10mm and 12mm, and has high repeatability and success rate.
