SMS: Spunbond non-woven fabric + meltblown non-woven fabric + spunbonded non-woven fabric = three-layer fiber web hot-rolled, which is a composite non-woven fabric. The non-woven equipment uses a double-bearing enclosed bushing with high precision , The fiber can be fully carded, and the cotton web will be evenly added. Non-woven equipment is mainly a kind of mechanical equipment that uses non-woven fabrics, melt-blown fabrics, etc. as raw materials, and uses the pressure-cutting function of ultrasonic waves to produce filter cotton of various shapes and sizes. It produces spunbonded and melt-blown composite products. , Has the advantages of high strength, good filtering performance, no adhesive, non-toxic and so on. It is non-toxic, tasteless, and highly effective in separating bacteria. Through the special treatment of the equipment, it can achieve antistatic, anti-alcohol, anti-plasma, water repellent and water production properties. Mainly used in medical and health labor protection products such as surgical gowns, surgical caps, protective clothing, hand washing clothes, handbags, etc. The thin SMS non-woven fabric (10-25gsm), due to its waterproof and breathable properties, is especially suitable for the sanitary market, such as sanitary napkins, sanitary pads, baby diapers, adult incontinence diapers, side leakage prevention and backing, etc. Medium-thickness SMS non-woven fabric (25-50gsm), suitable for use in medical treatment, making surgical gowns, surgical wraps, surgical drapes, sterilization bandages, wound placards, plasters, etc. It is also suitable for industrial use. Make work clothes, protective clothing, etc. SMS products are more suitable for high-quality medical protective materials due to their good isolation performance, especially those SMS products that have undergone three anti-static and anti-static treatments, and have been widely used worldwide. Thick SMS products (>55gsm) are widely used as high-efficiency filter materials for various gases and liquids. At the same time, they are also excellent high-efficiency oil-absorbing materials. They are used in industrial waste water degreasing, marine oil cleaning and industrial wipes.

The China Industrial Energy Conservation and Cleaner Production Association recently held the "Energy-saving Copper-clad Aluminum Pipe Busbar" scientific and technological achievements appraisal meeting in Beijing.
Experts attending the meeting listened to the technical report on the development of energy-saving copper-clad aluminum tube busbars, on-site inspection report, new report, user application report, etc., reviewed the appraisal data, investigated the results of samples and production sites, and Samples were rated for temperature rise and insulation withstand voltage tests.
After questioning and discussion, experts unanimously stated that the performance test of the product of Zhaoxi Dianhua's products through the electric power industry's electrical equipment quality inspection and test center for temperature rise of the rated current of the product, insulation and pressure resistance, the results were qualified, and the technical performance indicators were in line with: Q/BLRZ2-2013 "Energy Saving Copper-clad aluminum pipe busbar" enterprise standards and related national standards. The products were tested by the test team of the appraisal committee and the results were qualified. The product was evaluated by SGS (Standard and Technical Service of Standard & Technical Service Co., Ltd.). Under the condition of 4000A, the energy-saving effect of the copper-clad aluminum pipe busbar compared to the copper bar was significant.
Experts indicated that the design of energy-saving copper-clad aluminum tube busbars is novel, which has improved the effective utilization of copper, increased the effective cross-section of the conductor current, improved the non-uniform coefficient of current density, and reduced the rated current temperature rise to ≤30K. It has achieved the advantages of reducing line losses, improving the safe running performance of busbars in a hot environment, prolonging the life of insulating materials, saving copper materials, reducing conductor weight, and enhancing mechanical strength. This achievement fills the gaps in the domestic market and the technological level is advanced internationally.
The experts agreed to pass the results of technical appraisal. Experts in the assessment believe that the production site, process equipment and testing equipment of Rizhao Zhaodian can meet the production requirements. It is recommended to further strengthen the application of theoretical research and process optimization design and establish and improve relevant standards.
