技术领域technical field
本发明涉及钢化玻璃破拆技术领域，具体涉及一种基于自蔓延技术的钢化玻璃破拆方法。The invention relates to the technical field of tempered glass demolition, in particular to a tempered glass demolition method based on self-propagating technology.
背景技术Background technique
钢化玻璃是将普通退火玻璃先切割成要求尺寸，然后加热到接近软化点的700度左右，再进行快速均匀的冷却而得到的，通常5-6mm的玻璃在700度高温下加热240秒左右，降温150秒左右。8-10mm玻璃在700度高温下加热500秒左右，降温300秒左右。总之，根据玻璃厚度不同，选择加热降温的时间也不同。钢化处理后玻璃表面形成均匀压应力，而内部则形成张应力，使玻璃的抗弯和抗冲击强度得以提高，其强度约是普通退火玻璃的四倍以上。Tempered glass is obtained by cutting ordinary annealed glass into the required size, then heating it to about 700 degrees close to the softening point, and then cooling it quickly and uniformly. Usually, 5-6mm glass is heated at 700 degrees for about 240 seconds and cooled for about 150 seconds. 8-10mm glass is heated at a high temperature of 700 degrees for about 500 seconds and cooled for about 300 seconds. In short, depending on the thickness of the glass, the time for heating and cooling is also different. After tempering, uniform compressive stress is formed on the surface of the glass, while tensile stress is formed inside, which improves the bending and impact strength of the glass, and its strength is about four times that of ordinary annealed glass.
由于钢化玻璃破碎后，碎片会破成均匀的小颗粒并且没有普遍玻璃刀状的尖角，从而被称为安全玻璃而广泛用于汽车、室内装饰之中，以及高楼层对外开启的窗户。然而，钢化玻璃在给我们带来安全和便利的同时，也带来的一些问题。例如，当事故发生的时候，人们通常需要快速破坏钢化玻璃制备的门窗来逃生和救援；当军警执行任务时，需要快速的破拆钢化玻璃制服歹徒。而由于钢化玻璃强度远远大于普通玻璃，破拆难度很大，现有常规破拆方法为：1.使用安全锤等类似工具猛烈锤击。这种方法对操作人员的力量要求高，普通人无法完成，即使成功破拆也需要很长的时间，并不能起到应急的作用；2. 用爆破方式来破坏钢化玻璃的破玻器，一是使用时自身爆炸威力大，容易伤人 ；二是爆破钢化玻璃时玻璃会飞出大量高速飞片，同样容易伤人 ；三是爆破品属于国家高安全管制物品，限制在公共场所使用，不利于推广运用。After the tempered glass is broken, the fragments will be broken into uniform small particles and there is no general glass knife-like sharp corner, so it is called safety glass and is widely used in automobiles, interior decoration, and windows that open to the outside on high floors. However, while tempered glass brings us safety and convenience, it also brings some problems. For example, when an accident occurs, people usually need to quickly destroy the doors and windows prepared by tempered glass for escape and rescue; And because tempered glass strength is far greater than ordinary glass, it is very difficult to break open. The existing conventional break open method is: 1. use similar tools such as safety hammer to hammer violently. This method requires a high level of strength for the operator, and ordinary people cannot complete it. Even if the demolition is successful, it will take a long time and cannot play an emergency role; 2. The glass breaker that uses blasting to destroy tempered glass, first, the self-explosion power is large when used, and it is easy to hurt people;
近年来，为了克服这一难题，学者们进行了大量的研究。专利申请号201120416175.2与专利申请号201510041620.4公布了两种钢化玻璃破拆器，两项发明均利用高压气体驱动高硬度锤头撞击玻璃表面，撞碎玻璃。该破拆原理与安全锤基本相同，但是通过高压气体取代人力，克服了安全锤对操作者体能的限制。但是，高压气体生成原理类似于爆炸，拥有较大危险性。此外，由于钢化玻璃的强度很大，利用机械手段捶碎需要很大的力，在产生如此大气压的前提下还要保证装置本身不爆炸，意味着装置的壁厚、重量及工作时的冲击力很大，操作难度并不小，加之该装置为一次性使用设备，执行一次任务时需要携带多个以保证成功，更增加了实际应用中的限制；专利申请号201410597066.3公布了一种钢化玻璃破碎装置，该发明利用机械传动结构产生的静压力压碎钢化玻璃，但是该装置需要提前与钢化玻璃安装在一起，应用范围较窄；专利申请号201410823156.X公布了一种钢化玻璃切割方法，但是该方法需要在玻璃两侧同时操作，且整个过程需要几十分钟时间，适用于工厂精密切割，不适合抢险救援中的紧急破拆。专利申请号201510053001.7公布了一种钢化玻璃切割刀，通过电能加热刀锋，用高温刀锋切割钢化玻璃。但是由于玻璃的软化温度在700摄氏度左右，如此高的温度需要外部电源提供电能，电池无法满足。而在抢险救灾、反恐清障等紧急活动中，外部能源是难以得到的，如：高速路上、火灾现场、歹徒控制的大楼。应用受到较大限制。In recent years, in order to overcome this problem, scholars have conducted a lot of research. Patent Application No. 201120416175.2 and Patent Application No. 201510041620.4 disclose two types of tempered glass breakers. Both inventions use high-pressure gas to drive a high-hardness hammer to hit the glass surface and break the glass. The demolition principle is basically the same as that of the safety hammer, but by replacing manpower with high-pressure gas, it overcomes the physical limitations of the safety hammer on the operator. However, the principle of high-pressure gas generation is similar to that of an explosion, which is more dangerous. In addition, due to the high strength of tempered glass, it takes a lot of force to crush it by mechanical means. Under the premise of generating such an atmospheric pressure, it is necessary to ensure that the device itself does not explode, which means that the device has a large wall thickness, weight and impact force during operation, and the operation is not small. In addition, the device is a one-time use device. When performing a task, you need to carry more than one to ensure success, which increases the limitations in practical applications; Patent Application No. 201410597066. Tempered glass, but the device needs to be installed with the tempered glass in advance, and the application range is narrow; patent application number 201410823156.X discloses a tempered glass cutting method, but this method needs to be operated on both sides of the glass at the same time, and the whole process takes tens of minutes. It is suitable for precision cutting in factories, but not suitable for emergency demolition in emergency rescue. Patent application number 201510053001.7 discloses a toughened glass cutting knife, which heats the blade through electric energy and cuts toughened glass with a high-temperature blade. But because the softening temperature of glass is about 700 degrees Celsius, such a high temperature requires an external power supply to provide electricity, which cannot be met by batteries. In emergency activities such as emergency rescue and disaster relief, anti-terrorism and obstacle clearance, external energy is difficult to obtain, such as: highways, fire scenes, and buildings controlled by gangsters. Applications are limited.
基于上述技术的缺陷，本发明提供一种设备简单，操作难度低，成本低廉，速度快，环境适应性强且无须外加能源的钢化玻璃紧急破拆方法。Based on the defects of the above-mentioned technologies, the present invention provides an emergency tempered glass demolition method with simple equipment, low operation difficulty, low cost, high speed, strong environmental adaptability and no need for additional energy.
发明内容Contents of the invention
本发明的目的在于解决以上技术问题，提供一种基于自蔓延技术的钢化玻璃破拆方法，该破拆方法操作难度低，成本低廉，速度快，环境适应性强，且无须外加能源即可破拆钢化玻璃。The purpose of the present invention is to solve the above technical problems and provide a tempered glass demolition method based on self-propagating technology. The demolition method has low operational difficulty, low cost, high speed, strong environmental adaptability, and can demolish tempered glass without additional energy.
为解决上述问题，本发明采用以下技术方案：In order to solve the above problems, the present invention adopts the following technical solutions:
一种基于自蔓延技术的钢化玻璃破拆方法，包括以下步骤：A method for demolishing tempered glass based on self-propagating technology, comprising the following steps:
（1）清理钢化玻璃表面附着物，选取钢化玻璃上一点作为固定点；(1) Clean up the attachments on the surface of the tempered glass, and select a point on the tempered glass as a fixed point;
（2）点燃药筒A，灼烧固定点5-10s，所述药筒A的制备原料包括氧化剂、还原剂、稀释剂，通过调整氧化剂、还原剂、稀释剂比例使药筒A绝热反应温度为2100k-2500k以应对不同厚度的玻璃，均匀混合药粉后，装入筒，用引燃药封装筒；(2) Ignite the cartridge A, and burn the fixed point for 5-10s. The raw materials for the preparation of the cartridge A include oxidizing agent, reducing agent, and diluent. By adjusting the ratio of oxidizing agent, reducing agent, and diluent, the adiabatic reaction temperature of cartridge A is 2100k-2500k to cope with glass of different thickness.
（3）点燃药筒B，以固定点为中心，上下左右平移撩烧15-45s；撩烧完成后3-15s，钢化玻璃自动垂直垮塌，所述药筒B的制备原料包括氧化剂、还原剂、稀释剂，通过调整氧化剂、还原剂、稀释剂比例使药筒B绝热反应温度为2500k-2900k以应对不同厚度的玻璃，均匀混合药粉后装入药筒，用引燃药封装筒。(3) Ignite the cartridge B, take the fixed point as the center, move up and down, left and right, and burn for 15-45s; 3-15s after the burning is completed, the tempered glass will automatically collapse vertically. The raw materials for the preparation of the cartridge B include oxidant, reducing agent, and diluent. By adjusting the ratio of oxidant, reducing agent, and diluent, the adiabatic reaction temperature of cartridge B is 2500k-2900k to cope with glass of different thickness.
进一步，所述药筒A的制备原料具体为：Al、MnO2、CaSO4、CaF2；所述药筒B的制备原料具体为：Al、CuO、KNO3、CaF2。Further, the preparation raw materials of the cartridge A are specifically: Al, MnO 2 , CaSO 4 , CaF 2 ; the preparation raw materials of the cartridge B are specifically: Al, CuO, KNO 3 , CaF 2 .
进一步地，所述药筒A的火焰距钢化玻璃表面1-2cm。Further, the flame of the cartridge A is 1-2 cm away from the tempered glass surface.
进一步地，所述药筒B的火焰距钢化玻璃表面1-2cm。Further, the flame of the cartridge B is 1-2 cm away from the tempered glass surface.
进一步地，所述步骤（3）中平移撩烧的速度为10-20cm/s。Further, the speed of translational burning in the step (3) is 10-20 cm/s.
本发明利用化学反应产生的热量破坏钢化玻璃的应力结构，达到破拆效果。钢化玻璃加工完成后，玻璃两侧处于压应力状态，中部处于拉应力状态。药筒A用于破坏小范围内的应力结构，使得单侧剧烈受热，压应力松弛，由于玻璃传热很慢，另一次依旧处于压应力状态，在力的左右下，钢化玻璃出现“弯折”。药筒B用于将局部的应力破坏扩散到一个稍大的范围，造成一个稍大范围内的应力破坏。在经过药筒A的灼烧和药筒B的撩烧后，受热区域的应力状态和其他区域产生巨大差异，玻璃在应力不均的作用下，开裂破碎。The invention utilizes the heat generated by the chemical reaction to destroy the stress structure of the toughened glass to achieve the demolition effect. After the tempered glass is processed, both sides of the glass are in a state of compressive stress, and the middle is in a state of tensile stress. Cartridge A is used to destroy the stress structure in a small area, so that one side is heated violently, and the compressive stress relaxes. Since the heat transfer of the glass is very slow, the other time is still in a state of compressive stress. Under the left and right forces, the tempered glass appears "bending". Cartridge B is used to spread the localized stress failure to a slightly larger range, causing a slightly larger range of stress failure. After the burning of the cartridge A and the burning of the cartridge B, the stress state of the heated area is greatly different from that of other areas, and the glass cracks and shatters under the action of uneven stress.
氧化剂和还原剂的作用在于发生化学反应产生热量，稀释剂的作用在于吸收部分反应热量，使得反应柔和缓慢便于手持。The role of the oxidizing agent and the reducing agent is to generate heat in a chemical reaction, and the role of the diluent is to absorb part of the reaction heat, making the reaction soft and slow and easy to hold.
本发明一种基于自蔓延技术的钢化玻璃破拆方法，与现有技术相比，其突出的特点和优异的效果在于：Compared with the prior art, a tempered glass demolition method based on the self-propagating technology of the present invention has outstanding features and excellent effects in that:
1.方法设备简单：本发明利用化学反应完成破拆，无须任何辅助设备，只需提前储备一定量的药粉A、药粉B，即可临时根据玻璃厚度填装不同长度的药筒A、药筒B。1. The method is simple and the equipment is simple: the invention uses chemical reaction to complete the demolition without any auxiliary equipment, and only needs to reserve a certain amount of powder A and powder B in advance, and then temporarily fill the cartridges A and B of different lengths according to the thickness of the glass.
2.破拆速度快：整个过程在70S之内完成，速度远远快于现有破拆技术。2. Fast demolition speed: the whole process is completed within 70 seconds, which is much faster than the existing demolition technology.
3.安全可控性好：钢化玻璃为应力作用下的自然垮塌，垮塌时垂直下坠，不产生任何水平飞溅，安全性高。3. Good safety and controllability: the tempered glass collapses naturally under the action of stress. When it collapses, it falls vertically without any horizontal splash, and has high safety.
