The composite ceramic lining plate is a liner made of alumina (AL2O3) as the main material, supplemented by rubber, and processed by the vulcanization process. This kind of lining plate is mainly used on mechanical equipment with high wear.
The performance of wear-resistant ceramics conforms to the Q/OKVL001-2003 technical standard.
The main parameters are as follows:
-- Compressive strength ≥850 Mpa
-- Fracture toughness KIC ≥4.8MPa m1/2
-- Bending strength ≥290MPa
-- Thermal conductivity 20W/m.K
-- Thermal expansion coefficient: 7.2×10-6m/m.K
The rubber used is divided into three categories: adhesive and impact-resistant rubber; heat-resistant adhesive rubber; cold-resistant adhesive rubber.
The main parameters of adhesive and impact-resistant rubber are as follows:
-- Tear strength (Mpa) ≥12
-- Tear-off extension (%) ≥250
-- Shore hardness (degree) 55-65
-- Tear-off permanent deformation (%) ≤24
-- Adhesion between rubber and ceramics (Mpa) (shear stress) ≥3.0
-- Temperature resistance ≤100℃
The main parameters of heat-resistant adhesive rubber are as follows:
-- Tear strength (Mpa) ≥7.5
-- Breaking extension (%) ≥300
-- Shore hardness (degree) 48-58
-- Tear-off permanent deformation (%) ≤16
-- Adhesion between rubber and ceramics (Mpa) (shear stress) ≥3.0
-- Temperature resistance ≤250℃
The main parameters of cold-resistant adhesive rubber are as follows:
-- Tear strength (Mpa) ≥12
-- Breaking extension (%) ≥350
-- Shore hardness (degree) 48-58
-- Tear-off permanent deformation (%) ≤24
-- Adhesion between rubber and ceramics (Mpa) (shear stress) ≥3.0
-- Temperature resistance ≥-50℃
The main features of the composite ceramic liner are as follows:
1. Wear resistance: alumina corundum ceramics, hardness above HRA85;
2. Impact resistance: The toughened ceramic formula ensures that the ceramic is not easily broken. The unique spherical design and high-quality buffer layer can resist the impact of large materials;
3. High temperature resistance: can run at 0℃-250℃ for a long time;
4. Acid and alkali resistance: The rubber adopts a new formula of acid and alkali resistance rubber, which can resist weak acid and weak alkali;
5. Anti-dropping: The ceramic rubber steel plate is vulcanized in one piece, and the combination is very firm; each piece of ceramic has a penetrating bolt that passes through the bottom steel plate and is firmly welded, with double insurance;
6. Easy installation and replacement: It is provided by a whole lining board, which is convenient for replacement and installation and reduces after-sales service;
