New functions and characteristics of diatomite as filler in papermaking process
Can be applied to filter paper (board) filler. Diatomite has been widely used in special purification requirements of wine, beverage food, medicine, oral liquid, purified water, industrial oil filter elements and fine chemical filter paper or cardboard filling agent. Filling the filter paper wit...Read more -
What is Diatomite ?
The main component of diatomite as the carrier is SiO2. For example, the active component of industrial vanadium catalyst is V2O5, the cocatalyst is alkali metal sulfate, and the carrier is refined diatomite. The results show that SiO2 has a stabilizing effect on the active componen...Read more -
Application of diatomite filter aid in titanium filtration (II)
Adding diatomite filter aid during filtration is similar to precoating. The diatomite is first mixed into suspension of a certain concentration (generally 1∶8 ~ 1∶10) in the mixing tank, and then the suspension is pumped into the liquid main pipe according to a certain stroke by the metering add...Read more -
Application of Diatomite filter Aid in titanium filtration (I)
The first step in the application of diatomite filter aid in titanium filtration is pre-coating, which means that before the titanium filtration operation, the diatomite filter aid is applied to the filter medium, namely, the filter cloth. The diatomite is prepared into suspension in a certain p...Read more -
Diatomite is a pest – repellent （II)
Canadian research shows that diatomite has two major categories: seawater and freshwater. Seawater diatomite is much more effective than freshwater diatomite in controlling stored grain pests. For example, a dose of 565ppm was given to wheat treated with seawater diatomite 209, in which rice ele...Read more -
Diatomite is a pest – repellent （I)
Stored grain after harvest, whether stored in the national grain depot or farmers home, if improperly stored, will be affected by stored grain pests. Some farmers have suffered serious losses due to the infestation of stored grain pests, with nearly 300 pests per kilogram of wheat and a weight l...Read more -
Distribution of diatomite in the world
Diatomite is a kind of siliceous rock, mainly found in China, the United States, Denmark, France, the Soviet Union, Romania and other countries. Our diatomite reserves of 320 million tons, prospective reserves of more than one hundred million tons, mainly concentrated in east China and northeast...Read more -
introduction of diatomite filter (II)
Technical performance requirements 1) Swimming pool with diatomite filter should use 900# or 700# diatomite filter aid. 2) The shell and accessories of diatomite filter shall be made of materials with high strength, corrosion resistance, pressure resistance, no deformation and no pollution of w...Read more -
Introduction of diatomite filter (I)
Definition of diatomite filter: with diatomite as the main medium, using the fine and porous diatomite particles to remove suspended particles, colloid and other impurities in swimming pool water filtration device.The filter precision of diatomite is high, and most bacteria and some viruses can ...Read more -
Prospect of diatomite insecticides
Diatomite is a kind of siliceous rock, mainly found in China, the United States, Japan, Denmark, France, Romania and other countries. It is a biogenic siliceous sedimentary rock composed mainly of the remains of ancient diatoms. Its chemical composition is mainly SiO2, which can be expres...Read more -
Technical principle of wastewater treatment by refined diatomite
Diatomaceous earth is called refined diatomite after separating and removing impurities symbiotic with diatom in the process of cleaning. Since the diatom concentrate is composed of non-conductive amorphous silicon dioxide diatom shells and superconducting diatom nanopores make the diatom surfac...Read more -
How to filter sugar with diatomite
In recent years, with the improvement of people’s living standard, the demand for refined sugar is also increasing. One of the processes for producing refined sugar is to produce refined sugar by remelting, filtering, sterilization and recrystallization. Filtration is the key process in th...Read more
