Different Sintering method:

Pressureless sintering

Pressureless sintering is considered as the most promising method for SiC sintering. According to different sintering mechanisms, pressureless sintering can be divided into solid-phase sintering and liquid-phase sintering. Through ultra-fine β- A proper amount of B and C (oxygen content less than 2%) were added to SiC powder at the same time, and s. proehazka was sintered to SiC sintered body with density higher than 98% at 2020 ºC. A. Mulla et al. Al2O3 and Y2O3 were used as additives and sintered at 1850-1950 ºC for 0.5 μ m β- SiC (particle surface contains a small amount of SiO2). The relative density of the obtained SiC ceramics is greater than 95% of the theoretical density, and the grain size is small and the average size. It is 1.5 microns.

Hot press sintering

Pure SiC can only be sintered compactly at very high temperature without any sintering additives, so many people implement hot pressing sintering process for SiC. There have been many reports on the hot pressing sintering of SiC by adding sintering aids. Alliegro et al. Studied the effect of boron, aluminum, nickel, iron, chromium and other metal additives on SiC densification. The results show that aluminum and iron are the most effective additives to promote SiC hot pressing sintering. The effect of adding different amount of Al2O3 on the properties of hot pressed SiC has been studied. It is considered that the densification of hot pressed SiC is related to the mechanism of dissolution and precipitation. However, the hot press sintering process can only produce SiC parts with simple shape. The quantity of products produced by the one-time hot press sintering process is very small, which is not conducive to industrial production.

Hot isostatic pressing sintering

In order to overcome the shortcomings of the traditional sintering process, the type B and type C were used as additives in the scuba, and the hot isostatic pressing sintering technology was used. At 1900 ° C, fine crystalline ceramics with a density greater than 98 were obtained, and the bending strength at room temperature could reach 600 MPa. Although hip sintering can produce dense products with complex shapes and good mechanical properties, hip sintering must be sealed, which is difficult to achieve industrial production.

Reaction sintering

Reaction sintered silicon carbide, also known as self bonded silicon carbide, refers to the process in which porous billet reacts with gas or liquid phase to improve billet quality, reduce porosity, and sinter finished products with certain strength and dimensional accuracy. take α- SiC powder and graphite are mixed in a certain proportion and heated to about 1650 ºC to form a square billet. At the same time, it penetrates or penetrates into the billet through gaseous Si and reacts with graphite to form β- SiC, combined with existing α- SiC particles. When Si is completely infiltrated, the reaction sintered body with complete density and non shrinkage size can be obtained. Compared with other sintering processes, the size change of reaction sintering in the densification process is small, and the products with accurate size can be prepared. However, the existence of a large amount of SiC in the sintered body makes the high-temperature properties of reaction sintered SiC ceramics worse.

Characteristics

6.A variety of condensation trapping methods to reduce unit pollution
7.Nitrogen purging system has better insulation and degreasing.
8.Patented insulation technology to ensure the long-term use of heating body
9.Exhaust gas combustion and filtration system meets emission standard

Quality control
Quality is the spirit of the products, is the key point decide a factory's future.Paijin take quality as the most priority issues in our daily work.To ensure the good quality of our products, we paid much attention on 3 aspects.
  1. Most important: Human. Human is the most important point in every work. We have complete training courses for every new worker, and we have rating system to rate every worker to a level (junior, middle, high), different level workers are apponted to different jobs with different salary. In this rating system, it's not only the skills, but also rate in responsibility and error rate, executive power etc. By this way, workers in our factory are willing to do the best in his work.And strictly follows the quality management rules.
  2. Best materials and components: We only purchase the best materials on market, we know that saves 1 dollar in material would cost 1000 dollars in final. The key parts like electric components and pumps are all brand products like Siemens, Omron,Eurotherm, Schneider etc. For the other parts made in China, we choose the best factory in industry and signed product quality guranntee contract with them,to ensure every component every parts we use in the furnace is the best quality products.
  3. Strict Quality management: We have 8 quality check points in the processes of furnace producing, Examination in each check point is carried by 2 workers and 1 factory manager is responsible for it. In these check points, materials and components, and every aspects of the furnace are double checked to ensure its quality. At last, before the furnace leaves factory, it should be final checked with heat treatment experiments.
