The casting material industry, which is the backbone of the group, dominates the production of furan resin, with 150,000 tons of annual capacity, which is at the top of the global list; filter products that break foreign monopolies and are identified by the ministry of science and technology as high-tech products in the national torch programme, with the highest sales in asia; and cold-core box resins, membrane sulfon resins, alkaline phenol platinum resins, coatings, solidants, inorganic glues, heat-preventing vents, smelting materials, among others. Products are widely used in the production of castings of products such as automobiles, ships, aircraft, wind and electricity, general machinery, precision instruments, and high-quality export castings, with products of international quality leading over 50 countries and territories。
Companies have always adhered to the concept of green low-carbon development and “one-stop procurement, all-round services”, relying on core technologies, offering a range of services such as product development, product application, process optimization, environmental governance, etc., and providing technical safeguards for stable and efficient production by clients. The industry pioneered the introduction of products and technologies such as low voc furan resin, ultra-low-input cold core box resins, double-layer composite filters, alkaline sand regeneration, workshop flue gas management to promote high-quality industry development through chain collaboration and innovation。
Jf-series alkaline phenol formaldehyde tree
The phenol resin process, also known as the alpha-set method, is used for the production of alloy steel, carbon steel, heavy manganese steel, ink cast iron, and aluminium alloy castings。
Product characteristics:
High intensity, which reduces the amount of resin added
• good environmental performance and improved working conditions at production sites
• better regenerative performance and improved utilization of old sand
Jf type of alkaline resin commonly used:
Common specification model for the hqg series solidifier:
Note: in order to adjust solidification speed, solidifiers hqg1, hqg10 and hqg20 can be mixed
The solidants hqg20, hqg60, hqg240 can be mixed
Saves a preservation period of 1 year under constant temperature avoidance light。
The zq series solidifier type is commonly used:
N. B.: saved under constant evasive light for one year。
Product packaging:
Leather packaging: 250 kg of iron drums and 1,000 kg of plastic cans
Solidant packaging: 25 kg plastic drum, 200 kg iron drum, 1000 kg plastic can。
Use method:
1. Ratio: resin 0. 8-2. 0% (sand weight), solidifier 20-25% (heavy weight)
2. Sand-making: first, the sand is mixed with a solidant and then added to the resin, usually for a period of 5-60 seconds
3. Validation velocity adjustment (a +b+c alkaline phenol resin solidifier self-control device may be used): replaces the solidifier of different species or mixs the solidifier of different solidifiers at different solidifier speeds, as shown in the figure below (20°c)。
The ratio of solidifiers recommended for various demodeling times under different temperature conditions:
Security precautions:
Jf series alkaliphenol resin
This product is alkaline and corrosive. Operators wear protective gear at the time of use; when exposed, wash and treat with liquid or biological salt water. (b) ingestion, consumption of sufficient warm water, vomiting, medical attention
2. Storage in cool, ventilated storage. Stay away from the fire, the heat. Keep the container sealed. It should be stored separately from the oxidizer, and the mixing should be avoided. Be equipped with appropriate variety and quantity of firefighting equipment. The storage area should be equipped with leak response equipment and suitable shelter materials
3. Direct mixing with solidant is prohibited and empty containers are prohibited from cutting and heating without thorough cleaning。
Hqg, zq series solidifiers
1. The product may have a stimulating effect. When used, the operator wears protective materials and is ventilated at the work site; once exposed, wash and treat with liquid or biological salt water
2. Storage in cold, ventilated storage. Stay away from the fire, the heat. Keep the container sealed. High heat, open fire or exposure to oxidizers pose a risk of combustion. It should be stored separately from the oxidizer, and the mixing should be avoided. Be equipped with appropriate variety and quantity of firefighting equipment. The storage area should be equipped with leak emergency equipment and suitable shelter materials
Empty containers are prohibited from cutting and heating without thorough cleaning。
