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:Why do people call a concrete mixer a cement mixer?
It developed as a layman's term, where as most people call concrete, or mortar cement not realizing that cement is only one ingredient in concrete and mortar. So because there are more laymen, than skilled tradesmen in the masonry business, the term stuck
Q:is a backhand spring on the grass any differant than a backhand spring on cement?
uhmmm a BHS in grass does not hurt.... bcuz of its mud....... thus u cant feel any pain rather than a BHS in the cement......think clearly cement is harder than a mud........... i hope it helpzzzz!
Q:How to make cement grout to match brown decomposed granite?
The cement color works but a number of small trials are required to get it just correct. The trials need to be made with an adequate size so the components can be measured accurately and reproduced when the sample color is developed. Even after you think you have the correct color, try your proportions once more with a slightly larger sample to verify the correct ratio has been selected. As you are aware the wet color is different than the dried color. I would start with the cheaper cements and only go up in costs if you are not coming up with the color you want. You may want to try using mixtures of different sand colors if the granite is not getting you to the color you want. This definitely is a trial and error project. You may want to go slightly to the darker side of a match in that as the new grout weathers it will lighten slightly. After the grout weathers a very thin mix of cement and pigment can be mixed up and the joints can be painted with the blend. If bad goes to worse you may want to paint all the joints to make them consistent. I have used Liquid Cement Color by Quikrete which I got at Lowes, it was a bear but finally came up with an acceptable match.
Q:Why does cement hardens when exposed with air and water?
Cement does not need to be exposed to air to harden. It can cure under water! This is why it's called hydraulic cement. Curing is one of the most important steps in concrete construction, because proper curing greatly increases concrete strength and durability. Concrete hardens as a result of hydration: the chemical reaction between cement and water. However, hydration occurs only if water is available and if the concrete's temperature stays within a suitable range. During the curing period-from five to seven days after placement for conventional concrete-the concrete surface needs to be kept moist to permit the hydration process. new concrete can be wet with soaking hoses, sprinklers or covered with wet burlap, or can be coated with commercially available curing compounds, which seal in moisture.
Q:Removing rubber cement stains from fabric?
Rubber cement is a remarkable product used in household repair and crafting projects. It's true gift is the ability to adhere two non-porous materials together. Problems arise when this product ends up on clothes, upholstery or carpet fibers. The use of soap and water alone for removal will leave remnants of the rubber cement behind. Even large spills are removable using the correct method and cleaning materials. Getting rid of rubber cement on fabric surfaces takes 30 minutes to an hour.
Q:building a pond, instead of pond liner using cement, will this work?
The concrete will invariably crack at some point. It might be two years down the road; it might be ten. But it will crack and it will leak.
Q:Best way to mix 25 pounds of cement?
challenging stuff. lookup in the search engines. it can help!
Q:advisable storage method of cement?
I know your friend and she (if I'm correct) is very much missinformed as to storage technique. As much as we both love her, (she's a fine lass) toss the advice. Your little friends need open air! There should be a small hook just under the hairline, on the neck, in the back...Find a comfy spot in the sun and hang 'em...they'll love you more for it.
Q:looking for way to inlay small stones or pea gravel into new cement walk way?
If okorder.com Keep in mind if smooth rocks are used this surface is very slippery when wet...but it looks beautiful
Q:what are the properties of cement and water?
cement consist of Oxides and water forms hydrates of these oxides
