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: in what ratio should i mix cement and water?
- There is no good set ratio. But use a bucket instead of a hose and when you get the right mix you can fill the bucket to that level every time.
- Q: WHATS THE DIFEREANCE BETWEEN CEMENT, AND CONCRETE?
- Cement is the powder made from limestone, clay and gypsum that is the binder for making concrete. Concrete is the product of mixing cement with sand and/or gravel and water. Sidewalks, bridges and buildings are concrete, not cement.
- Q: Can a grenade blow through brick/cement wall?
- Most definitely.
- 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.
- Q: does quarry dust have cements properties?
- Ideally what you want to have is a wide range of aggragate sizes for the best concrete, with a good variation in sizes from small to large. It seems to me that if you took the quarry dust and mixed it towther with a latex fortifier and portland cement you could make a good thinset mortar, which would be better suited for thinner applications and small cracks and joints.
- Q: what weighs more? cement or sand?
- we all know for sure that a pound is a pound :p whether it's cement or even feauthers.. but I guess that she means what is heavier and most suitable to be in a small bag ( then for sur cement is ) cause a pound of cement is smaller in the quantity so you in a smal bag you can carrry more cement than sand ) ;)
- Q: i'm replacing the old wall in my tub with hardibacker. can i screw it on the tub lip? coz the instructions said that it should be screwed or nailed 3/8quot; from the eges.
- Don't place it over the lip. Your cement board, or greenboard for that matter, should rest on top of the lip. Then you fill in the gap with thinset and mesh tape. That way the wall doesn't bulge out at the bottom on all three sides making the tiling harder to do.
- Q: What do I do? Is it harmful?
- Call the emergency vet.
- Q: How do I jack out a 5 ft. high garage cement wall that is bowing in. It keeps getting worse?
- a poured concrete wall is bowing in? or a cement block wall is bowing in? either way , find out why. correct that problem and if it is concrete i dont think you can just jack it out. if its block you may be able to tear some of it out and have it re-laid...
- Q: I've tried to make the cement (on Whuddle World) and it always says that i'm unable to make it.WHY!?!
- to mix a cement, u need this : 1 bag full of cement a bottle of water ( u need oil to pump water. for oil, just go to gadget n gizmos, enter the 1st lab, click oil can near pink tube) sand ( get it free at playground (NE ww) bucket ( talk to farmer noggin, then search it by clicking around a pile of hay in farmer barn.. keep clicking till you find it) a trowel ( go to hickory hardware n woodworks, click a garden spade which is hanging on the wall. just keep clicking around it till u'll receive msg that wud kraft let u borrowed his trowel) now only u can mix it by clicking ur bucket in ur omnimbus. click use bucket and u now can start mixing it by dragging the items in correct order. 1. bucket, 2. cement. 3. water. 4. sand now u just mix the cement and make sure u carry the it. go to charlie fountain and click the statue. n dont forget to talk to chelsea to receive your awards.. hope this help all whuddles.. cheer up!!!
