Perlite filter aid
Selected small-sized spherical rhyolite glass perlite ore with reasonable particle size distribution after crushing and screening, using clean natural gas after desulfurization essence as fuel, After selective baking, sintering and puffing at a high temperature of 1200°C, and then pulverized by a high-speed mill and air flow selection, it is obtained with a reasonable particle size gradation. White or light gray solid powder with mesh-like structure.
In the process of filtration to form a filter cake, under a certain pressure, the perlite filter aids are squeezed and connected to each other to form a rough filter gap. There are many inline channels, which are small enough to block micron-sized particles, but at the same time have 80%-90% void ratio, retains high continuous penetration ability.
The unique ultra-fine channel structure of Yingkang perlite filter aid makes it have better filtering effect and more obvious economy than diatomite filter aid. Therefore, in the past two decades, it has been widely used in the filtration of various food, industrial and other liquids.
Income Perlite Filter Aid Application:
Edible: beer, beverage, fruit juice, monosodium glutamate, sugar, pharmaceutical, vegetable oil, seaweed gum, citric acid, etc.
Non-edible categories: petroleum, chemical, fine chemical, biochemical, metallurgy, preparation, water treatment, filler, etc.
Characteristics of Yingkang Perlite Filter Aid:
1. Ultra-lightweight type
The density of Yingkang pearl filter cake is only 120-250kg/m3. Compared with other types of filter aids, the filter cake density can be reduced by 20%-50%.
2. Chemical stability
The main components of Yingkang perlite filter aid are silicon dioxide and aluminum oxide, which is a white solid powder composed of inert amorphous glass particles. Insoluble in strong acid and alkali, good chemical stability. It does not contain organic matter, and can achieve 100% sterility after being roasted at 1200 ℃ in the production process.
Yingkang perlite filter aid has ultra-light weight, so that the product purchased by weight can effectively reduce the amount of use when the thickness of the coating is the same, and the comprehensive economy can be greatly improved. This is particularly evident in rotary drum filters.
4. High permeability
Compared with other types of filter aids, the unique filter gap structure of Yingkang perlite filter aids has higher permeability and significantly improves the filtration efficiency.
5. Easy to pre-coat, no cracking, easy to clean
6. Safe use
Yingkang perlite filter aid has no harm to human body, has no influence on the essential characteristics of filtrate, and does not have any potential pollutants.
