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: I have an 8x10 slab against the house, I would like it to be extended to an 12x12. How much would it cost to have someone pour it?
- That should be more than easy enough to do yourself. A little research on the internet or a friend that might know something would be ideal. Cement is a little pricey right now, but, that is a small enough area it shouldn't be much of a factor. We're talking about maybe between $100-$200 for cement.
- Q: i.e. if a concrete slab is 10m3 how many bags of cement are needed?
- You have to consider first or decide on the strenght or class of concrete.
- Q: if i have a footing 22ft long by 18inches deep by 10inches wide how many yards do i need
- Your cement company (provider) can help a great deal here. There are different consistencies of concrete, talk to the them and follow their recommendations.
- Q: General taxpayer commerce company sales of cement, building materials products should be handed a few points
- General taxpayer commerce company sales of cement, building materials products, applicable 17% VAT rate
- Q: ok im thinking of remodeling and there is a hideous cement floor, i want a carpet...How do i do it? thank you
- underlay grippers and carpet
- Q: what are some pro and cons
- Cement counter tops are more expensive than Granite, per square foot. Very labor intensive to build. You then need a good sealer and need to be careful about stains.
- Q: i was told not to use anything that would seal the cement, and that the object needs to breath.
- As a rule, sealing cement as with other porous materials is generally a good idea. The reason being is that should moisture absorb into the cement with a nice coat of paint, the first thing to happen is that the paint can pop off. In chunks if it's oil or thin flakes in latex. Either way I would suggest painting with any finish you like and use coat of xterior primer as well. Otherwise, your turtle will continue to drink all the paint you could put on it.
- Q: The wind knocked over part of our wood fence. Two of the wood posts that were cemented into the dirt were uprooted. I figure the best way to fix the fence would be to use new posts (or bust off the old cement) and bury them in the ground with fresh cement. I'm feeling lazy and wonder if I do as good of a job just burying the old posts with the old cement back into the ground. Will it hold? Maybe this is a no-brainer for some folks - useful comments appreciated.
- I would probably pour new cement for the reason that when the cement is wet it conforms to the hole dug and seeps in a bit therefore it seems it would be more stable than digging a hole and putting the existing post with dried cement then filling it in with loose dirt. Also, the ground around the new wet cement would be undisturbed and is still hard, you know, not like the loose dirt that would surround it if you just reburied it.
- 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!!!
- Q: What is the wood template and the iron template? Where can I buy? There are triangular iron. The More
- Wood template and steel formwork is also a building material, steel template you can go to the steel market to purchase, wood template you purchase woodworking board on the line are generally made on-site production, triangular steel can be made with steel.
