Charcoal Briquettes, also known as manufactured charcoal, firewood sticks, artificial charcoal, recycled charcoal, and smokeless clean charcoal, are made by high-temperature pressing of wood chips. They have a high density and hardness, and are not easily broken. Their main advantages include ease of transportation, smoke and toxicity-free, long burning time, and no cracking. The main disadvantages are difficulty in ignition and a large amount of ash after burning.

Charcoal is made from raw wood by being baked in a charcoal kiln. Its main advantages include easy ignition, high flame and temperature during combustion, and less ash after burning. Its main disadvantages are that there may be some unburnt pieces, resulting in a little smoke. It is not made from hard shrub charcoal, as the carbon is loose and contains a lot of air, which can cause cracking during combustion and is easily crushed during transportation.

　　Barbecue charcoal produced in recent years is made from pure charcoal powder, mixed with coke powder, coal powder, and binder. By utilizing waste materials such as sawdust, wood chips, shavings, and split wood, the manufacturing cost is low and wood usage is conserved. It offers easy ignition, rapid flame-up, high flames, substantial heat output, no need for a poker, minimal ash, and long burn time.

However, currently, barbecue charcoal manufactured domestically using binders is prone to breakage during transportation and handling due to its low cold and heat strength. Its poor waterproofing results in a lack of strength after being soaked or splashed with water, making storage and transportation difficult. Additionally, the use of resins like polyethylene glycol in the binder increases the cost of the charcoal, affecting the economic benefits of the enterprise and making it challenging to promote in both civilian and industrial applications.

High-strength, low-cost, odorless, new barbecue charcoal binder for waterproofing, a solid high-performance barbecue charcoal binder. The barbecue charcoal made from it is not only cost-effective and excellent in waterproof performance, but also has high strength and does not pollute the environment during use. The stunning results from authoritative testing:

1. Excellent waterproof performance. Maintains original shape without dispersion after being submerged in water for several days, with wet-state strength reaching 440-600N per piece (compressive strength measured after being submerged in water for two hours).

2. High compressive strength. Compressive strength ranges from 720N to 1000N per piece, with a fall strength of 90-96%. Dense texture, emits a crisp sound when gently tapped; does not disperse or collapse when burned.

3. High product performance. Low ash content, good combustion resistance. The charcoal made from high-quality raw materials generally has a heat output greater than 7,000 BTUs, ash content <4%, and fixed carbon content above 80%.

4. Long-lasting burn. Easy to ignite, with stable combustion, no bursting flames or sparks. The burn time ranges from 2 to 4 hours depending on the quality of the raw materials, and emits a fragrant scent during combustion.

5. Product is eco-friendly. It does not emit any harmful gases during production and has no odor or smoke upon combustion. It is hygienic and convenient, making it an ideal choice for outdoor barbecues for individuals, families, and organizations.

6. High economic benefits. The charcoal produced by this technology typically costs 150-220 yuan per ton, whereas the current adhesive-based charcoal production costs up to 350-500 yuan per ton. This means an additional profit of 200-300 yuan per ton of charcoal.

The product of this technology is achieved by using high-quality biomass charcoal powder as the raw material, adding binder and sulfur fixing agent, and then mixing, kneading, cold pressing, and naturally drying or drying to obtain the product.
