Larocaine needed for leisure use is normally used for instance like , insufflated, it really is also easy to take it intravenous. It's not necessarily recommended to take the unusually high dosage amounts of larocaine to obtain a like rush, that the amount can be excessive it can be considered a main problem for your cardiovascular system. Insufflated a normal the amount of larocaine ranges from 100 close to 2 hundred mg, but newbees should start off with lesser levels, suggested are Fifty milligrams. In case that used intravenous, than the medication dosage could be far lower, however buyers even so use up to A hundred milligrams to reach greater effects. Application: larocaine is a local anesthetic with stimulant properties that some studies have shown to be half the potency of cocaine. Dimethocaine also presents strain on the cardiovascular systems, like cocaine (60%), with the potential to induce tachycardia which could be problematic for those who continuously redose. Additional reports of respiratory arrest have been noted.

Yihang activated carbon pellets for waste gas treatment is a very good adsorbent, it is the use of charcoal, various fruit shells and high quality coal as raw materials, through physical and chemical methods of raw materials for crushing, sieving, catalyst activation, rinsing, drying and screening a series of processes and manufacturing. Activated carbon pellets has the dual characteristics of physical adsorption and chemical adsorption, can selectively adsorb a variety of substances in the gas phase and liquid phase, in order to achieve decolorization and purification, disinfection and deodorization and decontamination. Activated carbon adsorption method is to use activated carbon as a physical adsorbent to concentrate the harmful substances produced in the process of electrostatic spraying on the solid surface, so that the waste gas can be purified and treated. The adsorption process is a physical process that occurs at the interface between solid and gas phases. Yihang activated carbon pellets is characterized by large specific surface area, developed pore structure, reasonable pore distribution, strong adsorption capacity, uniform particle distribution and high wear resistance. Used for purifying chemical raw gas, chemical synthesis gas, pharmaceutical industry gas, beverage carbon dioxide gas, hydrogen, nitrogen, hydrogen chloride, ethane, cracking gas, inert gas, etc.

Product Description The granular activated carbon used for solvent recovery is made from high quality anthracite coal as raw material and refined by physical activation method. It is black granular, non-toxic and tasteless, with developed pores, reasonable distribution of three types of pores and strong adsorption capacity. In a wide concentration range, GAC has stronger adsorption capacity for most of the organic solvent vapor. It is widely used in organic solvent recovery, such as benzene, ether, xylene, ethanol, acetone, gasoline, chloroform, carbon tetrachloride and so on. Granular activated carbon has the characteristics of high strength, fast adsorption speed, high adsorption capacity, large specific surface area, developed pore structure, moderate pore size, etc. The solvent recovery process using granular activated carbon is to pass the mixed gas containing organic solvent vapor into the reactor filled with activated carbon. The solvent vapor is adsorbed on the granular activated carbon by the strong selective adsorption capacity of granular activated carbon, and the purified air removing the solvent vapor flows out from the other end of the reactor. After the granular activated carbon is saturated, it stops adsorption and then regenerates. When it is regenerated, water vapor is generally used to remove the solvent adsorbed on the activated carbon, and then the desorption vapor is condensed and the organic solvent is recovered. The regenerated granular activated carbon is dried and cooled for recycling.

Product Description Coconut shell activated carbon for drinking water purification has the characteristics of good abrasion resistance, high adsorption performance and long use time. It has good efficiency in purifying pure water and high pure water. It is an ideal material for electronic industry beer and water purification equipment. In daily life, coconut shell activated carbon can basically be used in three aspects: 1. Drinking water treatment. 2. Ultrapure water treatment. 3. Swimming pools and aquariums. Technical Principle Coconut activated carbon for drinking water purification is refined by a special silver-loading process, and is widely used in water purifiers, mineral pots, drinking fountains and other purification equipment. Its water purification effect is higher than that of ordinary water purification charcoal. Activated carbon loaded with silver can also play a role in sterilization and inhibition of bacteria in accordance with the fretting effect of silver ions, removing peculiar smell, odor and trace toxic and harmful substances in the water. The purified water can be directly consumed. The silver-loaded coconut shell activated carbon for drinking water treatment can be used for pure water purification, sterilization, removal of organic matter, harmful substances and heavy metals, and can be used as a water filter and filter element filling. The coconut shell activated carbon used for drinking water treatment is also the carrier of fluidized bed and floating bed biological treatment systems. It is used to remove a variety of organic and inorganic pollutants in water, such as phenol, cyanide, mercury, and hexavalent chromium ions, and absorb peculiar smell, chlorine and chroma in water.
