Introduction of variable pressure oil adsorbent activated alumina:

Activated alumina white spherical porous particles, uniform particle size, smooth surface, high mechanical strength, strong hygroscopicity, no swelling or non-swelling after water absorption, non-toxic, odorless, insoluble in water, ethanol.
Activated Alumina Under certain operating conditions and regeneration conditions, the drying depth of the product is as high as -90 degrees below the dew point temperature. This product can be used as a fluorine removal agent for high fluoride drinking water (except for fluorine capacity), and production of alkylbenzene. Defluorination agent for circulating alkane, deacidification regenerant for transformer oil, desiccant and purifying agent for industries such as oxygen production, textile industry, gas drying in the electronics industry, and drying instrumentation of chemical instrument wind, petrochemical drying, etc. (Dew point up to -40 degrees), etc., pressure swing adsorption in the air separation industry (dew point up to -55 degrees). It is a high-efficiency desiccant for deep drying of trace water. Ideal for use in non-thermal regeneration units.

The selection and dosage of activated alumina pressure swing oil adsorbent should have the characteristics of porous, strong activity and strong acid absorption, so as to adsorb water, peroxy compound, organic acid, carbonyl, etc. in the oil. Oil harmful substances. The commonly used and inexpensive ones are acid-free silica gel (coarse, fine-pored silica gel) and activated alumina. They are spherical and rod-shaped irregular porous solid materials, and have the following requirements for their properties:
1 water absorption rate > 20%;
2 acid absorption> 5mg (KOH) / g (silica gel);
3 water content <0.5%;
4 appearance is milky white.
Therefore, the adsorbent should be dried and sieved before being added to the oil purifier.
The amount of adsorbent is determined by the total mass of the oil. When using acid-removing silica gel, it is about 0.75% to 1.25% of the total mass of the oil, the smaller capacity transformer uses a large number; the large-capacity transformer uses a small number. When using activated alumina, it is about 0.5% of the total mass of the oil. Activated alumina http://

Pom Rod and sheet commonly known as Saigang, is a high-melting, high-crystallinity thermoplastic engineering plastic.


Anheda uses imported POM resign,import production equipment and self developed technology for the production of POM sheets and rods.It is produced by only virgin grade resin without any recycle material added.There are two colors of white and black.The density of POM  Rod and Sheet is 1.42g/cm³.

POM rod and sheet made by AHD has high mechanical strength,high rigidity,sliding and abrasion resistance,good creep resistance,physiological inertia,it is very suitable for food contact.

POM Rod and sheet are widely used in the manufacture of various sliding rotating machines, precision parts, gears, bearings and the like. The use of the industry is in the fields of automobiles, electronics, clothing, medical, machinery, sports equipment and so on.
