Product Description
Introduction
The pore size of 3A molecular sieve is 3 Å . It does not adsorb any molecular larger than 3 Å. It is an alkali metal alumina-silicate, the potassium form of the typ A crystal structure. 3 Angstrom, is obtained when part of the sodium ions of the 4 Angstrom sieve are replaced by potassium ions. Will adsorb, in sequence of adsorption rate, helium, neon, nitrogen and water.
According to the industrial application specialties, we endue our products with the characters of higher adsorption speed, stronger crushing and anti-contaminative resistance, more cyclic times and longer work-span. All these advantage have made it come to be the most essential and necessary desiccant in the fields of the deep drying, refinery, polymerization for cracked gases, ethylene, propylene and any other non-acidic gases or liquids in petroleum and chemical industrials.
Application
Molecular Sieve 3A is mainly used to remove moisture and can be applied to liquefied and gaseous materials on the whole. The main uses are as follows.
1) Drying of refrigerants (e.g. R22, R134a etc)
2) Removing moisture in paint and PU Plastic
3) Drying of natural gas.
4) Cracked Gas Drying.
5) Static dehydration of insulating glass units, whether air filled or gas-filled.
6) Drying of highly polar compounds, such as methanol and ethanol.
7) Drying of unsaturated hydrocarbons (e.g. ethylene, propylene, butadien).
8) Drying of olefins drying, ethanol, etc.
9)Dehydration of many kinds of liquids (say ethanol) air, refrigerant , natural gas or methane , cracked gas, ethylene, ethyne, propylene or butadiene .

Regeneration
1. Removing the moisture
You May use the dry gas like nitrogen, the air, the hydrogen, the saturated hydrocarbon and heat the gas up to 150-320ºC. Firstly you need let the hot gas purge through the molecular sieve bed with the pressure of 0.3-0.5kg/m2 for 3 to 4 hours. Then change to dry cold gas for 2-3 hour, at last you need isolate the molecular sieve from air and cool it to room temperature.
2. Removing the organics
You can use the water vapor to take the place of organics, then use the method 1.
You can also use the hot water vapor or inner gas pass through the molecular sieve under
the temperature of 200-350ºC (couldn't use the gas which will explore when to mix with the adsorbed organics).
3. Removing the gas
You can reduce the pressure to regenerate the molecular sieve.
Package

4. Professional manufacturer
PingXiang Mi'Ao Packing Co., Ltd is located in the chemical filling manufacturing base, PingXiang City, JiangXi province, China. In China, almost all chemical filling including plastic filling, ceramic filling, metallic filling are manufactured in our City. We are the most famous one not only because of our professionality but also the best quality.
Our popular products include infrared honeycomb ceramic plate, plastic hollow ball, zeolite molecular sieve, plastic chemical packing rings, ceramic packing rings, metallic chemical packing rings. All of our products are not only sold to the whole country but also exported to many foreign countries such as USA, Rotterdam, UK, Russia, India, Thailand, Singapore, Malaysia and so on.
Our most famous products are infrared honeycomb ceramic plate and plastic hollow ball. The infrared honeycomb ceramic plate is used for BBQ grill, indoors heater, household stove which can store heat, save energy, reduce CO emissions. We have more than 40 sets of molds for all standard sizes in this field and can make new mold according to customer's special requirement. We also get CE certificate and meet requirement of USA and Europe market. In industry field, plastic hollow ball could be used in the chemical tower or in the pool to cover the liquid surface which can avoid the bad smell and the liquid volatilization.
The colorful small plastic hollow ball could be used as liquid level floating mark ball. We also provide depolished and polished plastic hollow ball based on different usage. The normal material is PP, PE, RPP, PVC, CPVC, PVDF and so on. The ball sizes are from Dia 6mm to Dia 100mm. It could also customized.
The zeolite molecular sieve include 3A, 4A, 5A, 13X, we are the leading company in this field.
In the following few yeas, our focus will be the international market. We will try all of our best to bring our products to the world and let more and more people know our products and service.
