There is currently no accurate definition of "system doors and windows" at home and abroad. In the past, everyone thought that the system doors and windows were synonymous with energy-saving doors and windows, or that the system doors and windows were high-performance doors and windows. These are all one-sided. The system door and window is made by the system company to adopt the integral door and window system solution, and make a clear commitment to the performance and quality of the product. It needs to consider water tightness, air tightness, wind pressure resistance, mechanical strength, heat insulation, sound insulation, anti-theft, sunshade. A series of important functions such as weather resistance and handling feel, as well as the comprehensive results of the performance of equipment, profiles, fittings, glass, adhesives and seals. According to the requirements of the overall solution, we design, manufacture, install, and realize the promised performance and quality indicators in actual use. Simply put, to make the system doors and windows, there should be an early target setting. System doors and windows can not be easily compared with energy-saving, high-performance painting. At the same time, the system doors and windows emphasize the responsibility for the results. Therefore, system doors and windows are a perfect organic combination of performance systems. So what is the difference between the system door and window and the ordinary door and window?
Stability and performance aspects
The brand machine has its own independent technical department, which will carry out rigorous testing and inspection on all parts of the brand machine, so the compatibility is very good, and it is not easy to malfunction, which is the stability that we often say. The assembly machine is to assemble different computer parts according to their own needs for assembly, but there are some problems in the process of use, and the stability is relatively poor. After two to three years of research and development of the system door and window, the products and the performance and quality of the entire door and window are fully tested, and the mature products launched after the expected goals are achieved. Ordinary doors and windows are door and window products that are temporarily integrated for a single project and are often not fully tested.
Flexibility
The components of the brand machine have been fixed, and the selection is small, so the flexibility is small. In this regard, the assembly machine has great advantages, and it can flexibly configure its own computer according to its own needs. System doors and windows are serialized and standardized products. The slot structure and material supply have strong exclusiveness and incompatibility. The series can only be selected according to the needs of the project. Generally, the individual projects will not be developed. Ordinary door and window materials can be selected by domestic and foreign manufacturers, and can also be temporarily opened for flexibility.
Software aspect
Generally, the assembly machine only sends a mouse pad, a dust cover, a socket, and the like. In addition to these, the brand machine will usually be accompanied by genuine anti-virus software, genuine operating system. System doors and windows provide design software, design manuals, procurement manuals, processing manuals, professional special equipment and technical service support. They are a complete industrial chain. The quality of ordinary doors and windows depends on the level of the designer and the ability of the door and window enterprise to process and install.
After-sales service
The warranty period of the brand machine is longer than that of the assembly machine. In addition, the brand store can perform simple maintenance. If the assembly machine breaks the parts, it needs to send the parts to their respective manufacturers for repair. One word in the line is that the brand machine sells the service, and the assembly machine sells the benefits. In addition to the engineering warranty of the door and window unit, the quality assurance of the system door and window, as well as the system company's product warranty.

High Purity Graphite refers to Graphite Carbon content > 99.99%, widely used in high-grade refractory material and coating of metallurgy industry, military industry, fire engineering pencil lead on material stabilizer, light industry, electrical industry of carbon brush, electrode of battery industry, fertilizer industry catalyst, additive, etc.
Performance: the scales of crystallization is complete, thin and toughness, good physical and chemical performance, good thermal conductivity, temperature tolerance, self-lubrication, conductivity, thermal shock resistance, corrosion resistance and other properties.
Description: high purity Graphite (aka: scaly high thermal conductivity carbon powder) has high strength, good thermal shock resistance, high temperature resistance, oxidation resistance, resistance coefficient, corrosion resistance, and the advantages of easy to precision machining, is the ideal inorganic non-metallic materials. Used for processing and production of electrical heating components and smelting casting mould structure, high purity metal with boat, single crystal furnace crucible with heater, edm graphite anode, metal plating, sintering mold, tube, semiconductor technology with graphite crucible, launch tube, thyratron and mercury rectifier with graphite anode, grid, etc.
Characteristics and applications: high purity graphite with high strength, high density, high purity, high chemical stability, uniform and compact structure, high temperature resistant, high conductivity, good wear resistance, self-lubrication, easy processing characteristics, widely used in metallurgical, chemical, aerospace, electronics, machinery, nuclear power and other industrial fields. Especially high quality high purity graphite, as an alternative material, has wide application space in high technology and new technology field and has wide application prospect.
The purification methods are divided into two categories: first, wet purification, including flotation, acid and alkali, and hydrofluoric acid. The second is fire purification, including chlorination roasting and high temperature method.
High purity graphite
Is widely used in high-grade refractory material and coating of metallurgy industry, military industry, fire engineering pencil lead on material stabilizer, light industry, electrical industry of carbon brush, electrode of battery industry, fertilizer industry catalyst, additive, etc. High purity graphite through deep processing, but also produce graphite, graphite sealing material and composite material, graphite products, graphite antifriction additives such as high-tech products, become the important nonmetallic mineral raw materials of various industrial sectors.
