Wear resistant ceramic adhesive aging performance discrimination method

Wear resistant ceramic adhesive aging performance discrimination method

Wear-resistant ceramic adhesive paste plays a key role in project., directly affect the quality of the project, the general engineering contract warranty period is basically in about 5 years,  ceramic adhesive bonding performance sold in the current market is basically to meet the requirements,but products in anti-aging vary widely, good wear resistant ceramic adhesive aging period is up to eight years, poor wear-resistant ceramic glue water aging period is generally less than three years.  Wear resistant ceramic adhesive agining performance can not directly determine the quality of the adhesive from the appearance of color, status before use.also cann't determine from ceramics glue water adhesive strength after use,only can know when wear resistant ceramics start to fall off.

Here briefly introduce the discriminating method of alumina ceramic adhesive agining properties:The matching ratio of adhesive.The matching ratio is determined by the selected curing agent,The 1:1 and 2:1 adhesive basically choose cheap low molecular polyamide curing agent,This kind of curing agent with adhesive aging resistance is generally bad,Some manufacturer will make certain modification on low molecular polyamide,Such as adding a small amount of aromatic amine to improve the low molecular polyamide curing temperature resistance and aging resistance,But the increase is limited,the agining performance by this way is much less than choosing all Aromatic amines, fatty amine, alicyclic amine or amine reduction ,The ratio of adhesive by use all Aromatic amines, fatty amine, alicyclic amine or amine reduction will be 3:1, 4:1 or 5:1

Wear resistant ceramic pipe liner knowledge

Wear resistant ceramic pipe includes alumina ceramic elbow bend, alumina straight pipe, ceramic tee, section radius, adjustable pipe, mainly used for pneumatic, pumping slurry transportation and other materials.  Wear resistant ceramic    installed can effectively resist the shock effect, corrosive effect,thermal shock effect when the materials pass through the pipe wall , which can extend the life of the pipeline, thereby greatly reducing the frequent conservation costs incurred. Chemshun Ceramics is famous industry ceramic liner manufacuturer with pipe size 10mm ~ 500mm , we can effectively help customer to solve conveying wear damage problem with Al2O3 92% ,Al2O3 95% pipe liner , here we introduces wear resistant ceramic pipe performance advantages as follows : 1. Excellent wear resistant property, which can be used continuously for more than 10 years It was determined that the wear resistance of  alumina ceramic lining  is equivalent to 200 times of the manganese steel

Characteristics and applications of inert alumina ceramic balls

图片
   Inert alumina porcelain balls have the characteristics of high strength, high chemical stability and thermal stability. They can withstand high temperature, high pressure and corrosion from acids, alkalis, salts and various organic solvents. They are widely used in petroleum, chemical industry, fertilizers, natural gas and environmental protection industries. As a support and covering material for the catalyst in the reactor, it can buffer the impact of liquid and gas entering the reactor on the catalyst, protect the catalyst, and improve the distribution of liquid and gas in the reactor.       Inert alumina ceramic balls are used in industries such as environmental protection and environmental protection as covering support materials and tower packing for catalysts in reactors. Inert alumina ceramic balls have the characteristics of high temperature and high pressure resistance, low water absorption and stable chemical properties. It can withstand the corrosion of acids, alkalis a
