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.

- Q: Current rates for cement,steels,tiles,workers fee?
- sophisticated thing lookup at yahoo and bing that can help
- Q: Building materials sales company operating license business scope how to write
- (Except for dangerous goods), building waterproofing materials, cement products, industrial products, industrial products and other materials, according to their own specific business business, the following is a detailed business scope: construction company business scope: building materials, supplies, stainless steel products, aluminum products, chemical raw materials and products Insulation and anti-corrosion coatings, thermal insulation materials, waterproof leak-proof materials, pipes, valves and so on.
- Q: Is the cement used for dental crowns antibacterial?
- Hi, dental cements like GIC(glass ionomer cements), Resin cements help repel bacteria because of the fluoride release. They dont have antibacterial properties but only protects the tooth from adhering(sticking) bacteria. Zinc Phosphates with eugenol has bacteriostaric properties but it dissolves in saliva easily.
- Q: My sister is pouring a sidewalk alongside her house, and wants to have bare foot imprints of her and her two daughters. Its not my thing, but is this safe? I don't think wet cement can hurt you, but is it healthy to go barefootin' in, haha?
- Not a problem -- I did this a couple of times when I was a kid and there were zero complications at all.
- Q: I know it's mostly different names for the same thing, but there must be some differences. It might have something to do with adding sand and/or rocks to make a mixture, but I'm not sure.
- Your all wrong! Cement and sand and or gravel when mixed in a proprtion of 1-2-3, in that order, and water is added, becomes concrete when it hardens. Mortar, normally used to lay up large stones, brick, concrete block and the like, is cement with lime added, and sand, in a mix of 1-2, and water. The lime in the cement makes the mortar sticky so it adheres to what it is mortaring.
- Q: What is the density of cement?
- I will answer your question directly, then answer the question I think you are asking. Cement is a gray powder that is mixed with water and aggregate to make concrete. Cement and concrete are 2 different things. Cement is to concrete as flour is to cake. With that said, cement (the powder) has a specific gravity of 3.15, which means it's density is 3.15 times that of water. Water has a density of 62.4 pounds per cubic foot, so cement has a density of 196.6 pounds per cubic foot. If you actually mean concrete, which is the hard grey stuff, then it has a density of about 150 pounds per cubic foot. Hope that's what you were referring to.
- Q: I've had braces and had a permanent lower retainer put in. Well the dentist removed it today and never scrapped the cement off of the back of my teeth. Anyone know of a way that I can get it off at home without having to go back to the dentist?
- You can't really get it off yourself. You need to go back to your orthodontist and have him do it. He must have forgotten to take it off. Usually they do a good job of removing the stuff.
- Q: It is cheaper to build a cement house than wood?
- No a concrete or concrete block building structure is significantly more costly to erect than a frame structure. Depending on where it is located, the concrete building may be more cost-efficient in the longer term due to its greater resistance to termites, wind and fire. It may also be less costly to maintain external finish. Still, there are lots of fine 100 year old frame homes around the country.
- Q: The different meaning of Cement Clinker and Clinker?
- Clinker is ground (usually with the addition of a little calcium sulfate) to become Portland cement. It may also to be interground with other active ingredients to produce: blastfurnace slag cement pozzolanic cement silica fume cement Clinker, if stored in dry conditions, can be kept for several months without appreciable loss of quality. Because of this, and because it can easily be handled by ordinary mineral handling equipment, clinker is traded internationally in large quantities. The freight cost is much lower than that for the equivalent amount of finished cement. Cement manufacturers purchasing clinker grind it as an addition to their own clinker at their cement plants. Manufacturers also ship clinker to grinding plants in areas where cement-making raw materials are not available. Happy Holidays !
- Q: I have a art studio that I am creating from the gound up. I don't have much money I need to do most every thing myself. A friend who was redecorating her kitchen gave me her cabnets that she took out the problem is the counter tops are in real bad shape. I would love to do a cement counter top as they will take a lot of abuse from all my projects.
- Not sure how it would be avoided, but cement is likely to splay, that is, chip off. It is a natural characteristic of this material.
