Molecular Sieve 4A
Molecular sieve 4A is an alkali alumino silicate;it is the sodium form of the Type A crystal strcture.4A molecular sieve has an effective pore opening of about 4 angstroms(0.4nm).Our 4A molecular sieve will adsorb most molecules with a kinetic diameter of less than 4 angstroms and exclude those larger.Such adsorbable molecules include simple gas molecules such as oxygen,nitrogen,carbon dioxyde and straight chain hydrocarbons.Branched chain hydrocarbons and aromatics are excluded.
Molecular Formula
Na2O Al2O3 2.0 SiO2 4.5 H2O

- Q: So when i was younger my mum had footprints in the cement of my siblings and i at a certain time and i was wondering whether you have to buy a kit or just stick your foot in the cement. Thought it seemed a bit ricky putting one's foot in cement in case it stuck there or cement was stuck to it.
- just stick ur foot in the wet cement then pull it out n rinse it off case closed
- Q: What is the ratio of cement to sand to make concrete?
- Sand, cement and water makes morter. For concrete there's an extra ingredient and that is gravel. The most common is 3:1:1 that is 3 of gravel , one of sand and one of cement. All this is often printed clearly on the bags of cement.
- Q: I would like to close up my a/c for winter. I have the insulation and plastic but do not know how to attach it to my cement walls. Cellophane tape, duct tape, electric tape and masking tape have all proved to fail (and pretty quickly too). Any suggestions from you wonderful Yahoo people? I would be grateful.
- Why do you have to attach it to the cement wall. These products are made to just enclose the unit which is all you need.
- Q: I want to do a flooring of my new house by Cement:Sand (1:3)ratio and would like to know the quantity of cement needed per square meter for plastering. The floor thickness will be 2~3mm.
- First of all flooring work by cement mortar is not at all permitted by Indian Standard Code. 3mm thick plastering with cement mortar ( 1:3) is also non specified item. However for 3 mm thick plaster with 1:3 proportion requires 3 kg. per Sqm . But as the plastered surface is not enough as flooring so the top surface to be finished with a coat of neat cement. Cement requires for neat finishing is 1.75 Kg/Sqm.
- Q: can anyone give me powerpoint presentation on the topic cement.it includes manufacture+properties+...............
- You cannot compete against $5.15 USD PER DAY (The minimum wage in Mexico) Cementos Mexicanos is one of the largest companies in the World. There are very few cement companies in the United States of America left. One day each one of them will be foreign or gone. (Foreigners own 81% of cement companies in the United States of America)
- Q: Ones cement concrete is set and solid, it is as hard as rock? How it happens?Are pebles or cource sand in it helps? Or is it cement powder that becomes hard?
- the cement powder is what gets hard. it is a chemical reaction where the point is to make the stone into a pourable item, then as it dries it turns back in to stone. the pebbles and sand are present to reduce cost and to help with expansion and cracking problems.
- Q: Looking for ideas on pouring a cement bartop?
- Make bowls in the cement for pretzels. How about having people write things in it when its wet? Maybe set in different types of wood, like cherry. How about small holes at the ends that lead to garbage cans.
- Q: ive just got my braces fitted today, and at the back of my mouth i have some cement to stop me biting hard and breaking my braces. The problem is i find this cement really uncomfortable. will the cement wear down a bit ? or i will i get used to it? please help x
- Both. I had braces years ago and it gets to a point where you don't even notice them anymore. If the problem continues just go back to the orthodontist and they should fix it.
- Q: We have very ugly cement floor for our outside space and want to change it up! We do not want to pour a whole new set of concrete however and we were wondering if we could use something to stick on top of our old concrete! :) We've heard mortar works...but we need direction plz help!!!!
- You would have to repour all of it and remove it, unless you don't mind placing the rocks on top and making the floor higher
- Q: is there any difference between vermiculite -cement and sand-cement pool bottom ? is it OK to use sand- cement mix instead of vermiculite?
- hard thing. look using a search engine. this can help!
