Molecular Sieve 4A
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: it can't be reused because of the heat exposureor also a building that has been torn down
- The concrete can be used for fill to raise the level of the ground at the edge of a slope to provide more level ground.
- 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
- Why don't you just build a swimming pool and put fish in it? Same difference.
- Q: why is cement and water the ingredients of mortar allowed?
- Both Cement and Water are the best ingredients for mortar allowed simply because Cement and water have the absolute best chemical reaction to make mortar !
- Q: bouncing the ball on the cement first then change to bouncing the ball on the carpet to see which floor the ball bounces the highest is my independent Variable the carpet? Is the dependent Variable the lower bounce on the carpet. Is the controlled variable the quality of the carpet
- Your independent variable is the thing that changes, which is the surface the ball is bounced on (like cement or carpet, but not just one of those) Your dependent variable is the variable that is effected by the independent variable, so the height that the ball bounces. Your controlled variable is the thing that does not change, the constant, so that would be your ball. Tips: for a good experiment, you should have more than 2 things in the the independent variable, so you should try other surfaces as well such as wood. Also, to avoid any error, buy multiple of the same ball and use each one on a different surface. That way the cement won't scratch the ball and cause friction between the ball and the carpet, but the balls will have the same bounce so it won't change the height.
- Q: If your whole body, except for your head, were to be buried in cement is it possible to survive?
- No. The cement would harder, and your lungs couldn't move in and out. Your diaphragm couldn't move. You couldn't excrete waste either.
- Q: I spent ?800 on this and am really worried that this is wasted (the use by date on the paper wrapping is october 2008. I have opened one of the bags and there is still powder in it however there are hard bits. Is there anything i can now do with this cement? The builders start mid may. thanks
- Cement is basically grounded limestone,if you got the time and patience and are very frugal (cheap)you can smash it into powder again and use it. I had several bags of Portland cement (gray) that had small and large granules,I sifted all the bag and squashed the granules and use it to make concrete for my projects with no adverse results.
- Q: I'm wanting to get the quot;DIY Belgian-Style Stone Moldquot; by Pathmate to create a back yard area for my husband and I to enjoy the out doors some. One of the things I'm was wanting to do is to have all the concrete stones be a nice dark blue color so it would look good with the house and any outside furniture. I really don't want to just apply a coat of paint the surface of the stones. And i did read somewhere online that I could mix latex paint with water and concrete but i cant find any photos with the results. any suggestions? I do want this project to be as inexpensive as possible please help
- Maybe you could ask a concrete company close to you if you could buy a small amount of color pigment. They have charts there so you can see the colors and I am sure since you don't need that much for your project (it is not a whole driveway) they might sell you some. Ths way you know how it would look and that it works with concrete.
- Q: i need to cement some blocks in my my garden any help
- if you are laying a few blocks , you want mortar , not cement...buy a bag of type s mortar and mix it 3 to one...it usually takes about 8 shovels of sand to a half bag , which is about all you will want to mix at one time in a wheel barrow...mix with a hoe and add your water slowly so you dont flood it...
- Q: Why do the bulk cement trailers or the silo trailers use a peculiar shape?
- The secret to the shape is inside the drum. There are spiral fins welded to the inside of the drum. When you turn the drum one direction, the dry cement ingredients the water are pulled down into the drum by the direction of the fins, mixing everything together. When you arrive at the job site, the ingredients are all mixed into cement, and ready to use. The driver then reverses the rotation of the drum, and the mixed cement now is pushed out of the drum by those same fins, he pours the load, and goes back to the yard. The ingredients are loaded into the drum dry, then water is added. The drum then mixes it all as the truck is driving to the job site.
