I. Overview: From the Beijing Huaxia Keyuan Technology Development Center (select more good projects, please visit http://) Adhesive Expert Group developed a new type of special fire door rubber, mainly from sodium silicate, clay powder, fire retardant, polymer polymerization agent and other inorganic An inorganic polymer binder formed by mixing raw materials. When the product is fully dehydrated, the adhesive layer achieves the highest strength and is a good environmentally friendly fireproof door adhesive. Has a strong price competitive advantage. Second, characteristics and technical indicators: 1. Inorganic silica gel is non-toxic, non-flammable, odorless, does not contain harmful substances such as benzene, formaldehyde, etc., and the adhesive is cheap and has a strong competitive advantage; 2, with a strong bonding performance; 3, has a high degree of refractoriness (resistant to 1200 °C high temperature); combustion performance to A1 level. The smoke toxicity of the material is up to the safety level (AQ1); Third, product use: Can be used to bond aluminum silicate wool, rock wool, perlite fire board, vermiculite fire board, metal , ceramics and other materials and steel doors and wood fire doors and other materials; spray heating does not affect the strength of the adhesive layer. Fourth, bonding process: Fireproof Door Adhesive Bonding Process The surface of the steel plate must be clean and free of dust, rust, and oil before scraping. Place aluminum silicate cotton, rock wool, perlite fireproof board, vermiculite fireproof board and other filling materials. Joint door V. Production Conditions and Profit Analysis:? 1. Equipment investment stirrer one (can be self-made) 3000-5000 yuan, various measuring instruments, workshop 50-100 square meters, workers 2-3 people, 2. Existing chemical plants, adhesives factories and paint factories can produce without additional equipment. ? 3, the product cost 800 yuan / ton, price 1800-2500 yuan / ton. Six, technical services and costs:? 1. Providing manufacturers, who are responsible for formulation, process, personnel training and materials, for the concessionaire. 2. The technology transfer training fee is 20,000 yuan. 3. Charge d'affaires to do the test report of the green sign certification and the National Chemical Building Materials Testing Center and the National Environmental Testing Center (at their own expense). 4. At the same time learning security doors (steel doors) styrofoam technology, transfer fees. Training costs a total of 38,000 yuan. Technical consulting electricity 52693831 13301269298 15311210332 |
Deep Groove Ball Bearings
Deep groove ball bearings The out looks of them are nearly the same,the only different is the size,you may need other models please check the following table for reference.are the most widely used bearing type and are particularly versatile.
They have low friction and are optimized for low noise and low vibration which enables high rotational speeds.
They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than other bearing types.
Deep groove ball bearings are divided into the following series: 6000series, 6100series, 6200series, 6300series, 6400 series, 6700 series, 6800 series,6900 series,16000 series etc.
