The company has three individual manufacturing champions under its umbrella (two national and one provincial), 10 high-technology enterprises and five “specialized new” enterprises, namely, the national technology innovation demonstration enterprise, the agricultural industrialization national priority enterprise, the national intellectual property demonstration enterprise, the first national-level “green plants”, and china's manufacturing private sector enterprises. The company is the manufacturer of raw materials for the global condensation of the green energy-saving integrated use of the pilot and the shenzhou ship to return to the cabin to help china's space industry continuously from the launch of the shenzhou 8. The dominant products of furan resin and phenol resin are at the top of the global market, with chips using photogel resin, 5g communications pcb using electronic resins, and sanctuaries with light steel breaking foreign monopolies。
Innovation is the soul of the development of the spring. The company has a national centre for enterprise technology, with more than a dozen professional institutes with more than 400 scientific staff and an investment of more than 350 million yuan per year in research and development; it has a national post-doctoral research station, a sub-centre for the processing of biomass, a national accreditation laboratory, a priority laboratory for enterprises in shandong province and an engineering research centre in shandong province, among other scientific research platforms; it values research and development in the fields of production, including the chinese academy of science and technology, qinghua university, wuhan university, xianthang university, tianjin university, huadong teacher university, harbin university of industry, xiamen university, dalian university of technology, sichuan university and shandong university; it has established a long-term partnership with over 50 institutions of higher learning, including, among others, the national centre for the study of engineering and research in shandong province; it has awarded over 1,200 cumulative declarations of international and national patents, and has received the chinese patent award for excellence; it has undertaken hundreds of projects to draft standards and has produced a number of innovations。
The sanctuary will be driven by innovation and strive to move to a high end, along the lines of high-end, functional, refined and high-performance, continuing to increase investment in technological innovation in e-chemicals, biomedicine, nanomaterials, carbon materials, composite materials, new energy sources, striving to build low-carbon, ecological, circular, high-quality development systems, working to become the leading global provider of new biomass and chemical material solutions, and realizing the corporate vision of the “hundred-year sacred spring for the benefit of humanity”。
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。

Phenoloxane self-hard resin
Sanctuary phenol alkyl is developed for the rapid mass production demand of the self-hard sand line and applies to the production of casting steel, cast iron and coloured gold. The adhesive system consists of three components, i of phenol resin solution, ii of polyocyanate solution and iii of catalyst。
Product characteristics:
High intensity, low resin addition
The resin is highly active, solid and efficient
The resin system does not contain harmful elements such as s, p and so on
Zoom, low-tempered, low-intensity
• low level of free formaldehyde, low release of hazardous substances, environmentally friendly high
Specification model:
Methods of use:
Rate of accession of resins and catalysts
Breams added: component i: 0. 35% ~ 1. 0% (sand weight) and component ii: 0. 35% ~ 1. 0% (sand weight). The ratio between the two groups (60 ~ 45): (40 ~ 55)
The composition is high i, the initial strength of the type (core) is high and the amount of gas is low; the composition is high ii, the type sand can be used for long periods of time, the final strength is high, but the flue gas is injected and the amount of gas is high, increasing the risk of bright carbon and gas hole defects in the casting。
Catalyst quantity: usually 0. 5-5% of component i, determining the catalyst type and the addition based on the size and complexity of the core in order to ensure sufficient use time for the sand
Catalysts are added: metering pumps are added individually or with group i。
Mixing process
In the case of mesh sand mixers, different types of mixer equipment have different times, adjusted according to the time of mix recommended by the equipment manufacturer to ensure that the resin mix is even
(a) intermittent mixer resins: first grouping i resins (pre-introduced iii), then mixing with sands for a few seconds, and then adding ii resins, evenly and as soon as possible
Catalysts can be added individually if a continuous mixer is used; they can also be added along with group i, and when mixed, add a group i resin, followed by a group ii resin, and form or core immediately after sand。
Use recommendations:
1) timely maintenance of the mixing equipment to ensure the homogenization of the two resin mixtures
2) when the catalyst joins with the group i, the catalyst must be fully mixed with the group i and evenly mixed
3) mixed even catalysts and components i, preferably spent within 24 hours and too long, can cause problems such as increased solidification and reduced intensity。
Specific packing:
220 g/ barrel, 500 kg/ can, 1,000 kg/ can。
Security precautions:
1. This product irritates the eyes and skin and should be properly worn in protective clothing, gloves and mirrors/face masks and used in well-ventilated places
Upon eye contact, lift the eyelids, and immediately use a large flow of fresh or physio-saline water for continuous wash in 15 minutes
3 upon the use of the resin drums, the hood shall be covered and protected against water
4. Be careful during handling and handling
5. The product shall be stored in a dry ventilated area below 25°c in order to avoid suntanning, distance from thermal sources and severe restrictions on access to water
