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:if so, are there any special steps i need to do?
- If the mix you were using was guarenteed to not leak anything into the water it would be fine.
- Q:I have a small concrete slab (12' x 3.5') that I would like to cover with bricks. Should I use mortar or cement to affix them? We live in a cold and wet climate where summer max temp is 90F, winter min is -30F, lots of rain in spring and fall. Not sure if that makes a difference.
- hi im a builder in uk ...first ...mortar is building sand and portland cement ...do NOT add lime ..this is not used in this application ...you will need 3-1 mix ...by weight ..not volume ...you will need to use either a blue brick or a concrete brick ...a normal brick in this situation will not last 5 years in those winter temperatures ..the frost will blow the face off
- Q:Can cement be mixed with sea water instead of fresh water?
- The best practice is to use potable (fresh) water for a concrete mix design. If you are somehow left without another option the following information should help you make an informed decision. If the situation is regarding a structural portion of a home, business, bridge or otherwise important structure please seek a qualified engineer to help give you more specific information. If this is for a small project like a mailbox foundation or similar then I hope this information will be helpful in making a good choice. The answer depends on your steel reinforcing. If the concrete you are preparing the cement for will have steel reinforcing you will need to use corrosion resistant steel (such as stainless steel, MMX, epoxy coated, or galvanized) if you want to keep the steel from corroding prematurely due to the salt content of sea water. If you decide to use sea water in the mix and have steel anchor bolts embedded in the concrete, you will want to make sure that they are stainless steel or galvanized. Make sure that you use the same steel type (stainless or galvanized) for your bolts, washers, and nuts. Ultimately the saline properties of sea water will produce a harder concrete, but if that corrodes your steel your end result could be a dangerous failure. Your first choice should be to use fresh water in all but very special cases.
- Q:I need to repair my sidewalk and I've seen cement having these little cracks in it after it's dried; anyone knows of a way to prevent this?
- No matter what, a sidewalk repair will always crack along the same crack line. One cannot prevent this as the forces of expansion and contraction are along that line and the repair will always crack again. Cement does not dry. Cement polymerizes with water and the water becomes a permanent part of the cured cement itself. On your repair project, take and mix about 5 tablespoons of Latex paint to a batch of repair cement. This will prevent rapid curing of the cement and improve the bond onto the old concrete sidewalk. When you have finished the repair. Cover the repair with corrugated cardboard, two to three layers of it and soak it down. Always do a repair in the late evening as possible to keep the sun off of it.
- Q:my bottom part of my front teeth just fellcan dental cement help?oh..and it was root canal already..
- Temporary cement won't unfortunately help that much. You can resin filling placed to bond the pieces together. However, the ultimate restorability of the tooth depends on how far down the crack extends.
- Q:Here in the US they use sheet rock and the houses are so flimsy, but in DR they build them so strong and it's 100% cement. Why is that?
- Houses in tropical and sub-tropical climates are made of cement because of the problem of wood rotting or being destroyed by insects. Cement houses stay much cooler than houses built of wood and sheetrock ,too. BUT, cement houses do nto have heating systems , which are a definite need in houses in the U.S. Cement houses also have a lot of problems with mold.
- Q:i need to paint cement statues What do i paint them with. how do i paint them and where do i buy this paint? thanks:)
- Is this near/around a pool or water source? Cement must be sealed, then painted. Go to B. Moore paints or Bear paints. Lowes Home center carries both I think. The paint for cement is a special blend that must be used. Can use paint sprayer.
- Q:I bought a cement ladder ( not edible ) yesterday. today i put the cement ladder in the cage but he starts nibbleing the cement and tasting it ( i can hear the crunch flavor in his beak an swallowing it ) . HELP WHAT SHOULD I DO!!!!!!!!!???
- Im not sure....my bro bought cement for the birds that HELPS them digest their food....l.so maybe thats what he is doing
- Q:Quick question which is what is water Putty and Portland cement used for and back...way back in the day what was it used for?
- The British give this name to modern day cement. Ordinary Portland cement,sulphate resistant cement, white cement and Grey cement and so on. Most have chemical name but Portland is a patent name.
- Q:im building a fish pond and the onl way i can line it completly floor to wall is with cement rocks wont stick in a liner but ive heard the cement will contamnat the water was wondering if i could eliminate the cement toxin or if there is any compound similar to cement that wont put contaminates in the water
- Deb In addition to what has been said, also check the ph level of the well water to make sure it is not acid or alkaline. Because it has come out of the ground, it can be a lot different to rain or river water. It also won't have much oxygen in it, so you might need an aerator or something to churn the water surface. Finally check the water temperature and make sure in the summer, the temperature doesn't make the water too hot to harm the fish.
