Powder carbon is Huahui Company's third series of
products. Acid washed carbon is Huahui Company's fourth series of products. Through acid washing, alkali washing and special technologies, Huahui can produce < 3% ultra low ash activated carbon.The common produced varieties
are 30x200mesh, 60x200mesh, 100x200mesh, <200mesh, <325mesh etc.
Acid powder
activated carbon,made from coal, which is grinded into suitable powder size with qualified
activated carbon,is the third main products of HuaHui Company.
Because of its
powder state, better diffusivity, it can full touch to the reaction
material. Meantime, it is applying to
disposable recovery treatment of filling
water and industrial waste water with its high efficient adsorption, moreover,
also used for refining and
decolorization of liquid. The types we manufacture through the year
include HF-30x200, HF-60X200,HF-100X200,HF-325 etc.

The main role of the herbicides is to kill annual weeds. Excessive application can kill perennial shrubs and seriously damage vegetation and the ecological environment. After applying the medicine every year, the field is yellow. Especially on the river embankments and on both sides of the road, it is even more worrying.
Green vegetation greening environment is a natural barrier for soil and water conservation. After the application of the herbicide, the weed roots are destroyed, the regeneration ability is slow or not regenerated, and the residual residual toxicity is not conducive to the growth of crops. The author suggests that the relevant departments and township governments delineate and restrict the use of areas in the location, and use destructive herbicides carefully to protect the ecological environment. 
Killer herbicides use after leaving
In recent years, when farmers’ friends weeded in orchards and eliminated weeds in the fields, herbicides were widely used. Especially in some chestnut producing areas, because the chestnut garden is generally large in size, the task of eliminating weeds is heavy, and people use herbicides to weed. Although this saves labor and saves time, it does more harm than good, and it has endless troubles.
