China's explosion-proof electric heater products started relatively late, around the early 1950s, beginning with the imitation of former Soviet Union's coal mine explosion-proof electric heaters, gradually developing and forming a certain industry production capacity. So far, there are about 300 manufacturers with an annual output value of over 2 million yuan, producing more than 200 types of products, basically meeting the needs of the electromechanical product market and playing a significant role in China's national economic development.
Explosion-proof electric heater, as the name implies, is an electrical appliance that can prevent explosion accidents in places containing explosive dangerous gas mixtures. Currently, China's explosion-proof electric heaters are basically divided into two categories: one is called mining explosion-proof electric heater, mainly used in coal mines and mines with prominent explosive gases such as methane; the other is called factory explosion-proof electric heater, mainly used in all places except mines and coal mines, such as petroleum, chemical, textile, pharmaceutical, military and other enterprises, including gas explosion-proof and dust explosion-proof electric heater dust.
Since explosion-proof electric heater is a special electrical product, the state has formulated mandatory implementation standards for it. This is an important guiding document for standardizing the technology and quality of China's explosion-proof electrical products, and also an important basis for the production, use, and inspection of China's explosion-proof electrical products. Any explosion-proof electric heater must meet its standard requirements and obtain the product certificate "Explosion-Proof Inspection Certificate" issued by the explosion-proof inspection unit before entering the market. In recent years, the economic development of petroleum and chemical enterprises has been rapid, and the demand for factory explosion-proof electric heaters has also increased relatively. The production process of explosion-proof electric heater products is relatively complex and difficult to manufacture, but the profit is also considerable, so more and more manufacturers are producing explosion-proof electric heaters. The nature of these explosion-proof electric heater manufacturing enterprises has changed from the past dominance of public-owned enterprises to currently 60% to 70% being non-public-owned enterprises. In the process of China's economy transforming from a planned economy to a market economy, the weakening of industry management and insufficient law enforcement supervision of product quality have led many manufacturers to switch to producing factory explosion-proof electric heaters. Driven by huge economic interests, many enterprises have arbitrarily started production, and many have not yet understood the basic theory and knowledge of explosion-proof electrical equipment, hastily starting production, which inevitably brings huge hidden dangers to the explosion-proof electric heater product market. In addition, some enterprises, driven by profit, arbitrarily deviate from the explosion-proof standard requirements to obtain greater economic benefits. It can be said that the current explosion-proof electric heater market competition is very fierce, almost to the point of white heat. In such a disorderly and non-standard competitive production environment, we cannot but see that there are many problems in the entire technology development, production, management, and sales process of factory explosion-proof electric heaters. There are many fake, shoddy, low-quality, and high-priced products. Therefore, we must have a sufficient and clear understanding of the entire industry status of factory explosion-proof electric heaters.
China's factory explosion-proof electric heater products are currently in a new development period. We should take advantage of this very favorable opportunity to greatly improve the technology, quality, structure, performance, and appearance of China's explosion-proof electric heater products. Especially in conjunction with the upcoming issuance of production licenses for explosion-proof electric heater products, we should eliminate a batch of enterprises and products with backward technology and low quality, strengthen industry management, and strengthen technical quality supervision. China's explosion-proof electric heater products will surely develop rapidly.
