99.7 alsint Alumina Ceramic machinery machining parts
Reputation depends on quality, quality comes from Hard!
Alumina Ceramics:
Before casting, first put a shaped pipe network in the corresponding part of the master mold (2 cm away from the pouring working surface). The interface of these pipe networks can be connected to the vacuum and compressed air pipelines on the forming line. In order to drain, mold release and mold dewatering during pouring. Materials for making microporous pipe network are: microporous glass fiber hose, pipe diameter φ = 7.5mm; nylon wire for weaving grid φ = 9.5um: for mesh Resin impregnating solution (made of resin, catalyst, initiator, talc, etc.). These mesh materials are braided into a pipe network and cured in another specially-made auxiliary master mold. After being removed from the mold, it is used for The master mold is used. The gypsum used is β-gypsum or α-gypsum. The latter is 1 times higher in flexural strength than the former; the surface microhardness is 60% higher, and the tensile strength is about 2 times higher. But the standard consistency The water absorption rate is about 30% lower. Therefore, α-gypsum is more suitable for making high-strength gypsum models. (3) Microporous resin mold suitable for high-pressure grouting of sanitary porcelain And without pipe network. In order to meet the high-pressure grouting requirements of sanitary porcelain, the total compressive strength is not less than 20 MPa, and the pressure is 10 MPa. Should be no significant deformation under the action of water permeation rate of 0.10 ~ 0.13 m3 / m2s. This mold ...
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
