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.

Application

 

Drying and removing of CO2 from natural gas, LPG, air,inert and athmospheric gases, etc.

 

Removal of hydrocarbons, ammonia and methanol from gas streams (ammonia syn gas treating).

 

Special types are used in the air break units of buses, trucks and locomotives.

 

Packed in small bags, it may be used simply as a packaging desiccant.

Attention

 

To avoid damp and pre-adsorption of organic before running, or must to be reactivated.

Q:What is the best method for homemade Cement?(Not Concrete)?
concrete is made from cement,concrete is hard,cement is soup,u cant make cement at home,go to the big box home center and buy a bag of cement,follow instructions on bag
Q:Cement - renewable materials?
I would have to say C but B is also attractive. I could make the case that the rock that is used for cement is the result of hundreds of thousands of years in geologic processes. The energy spent to produce the cement is used. However, I could say that cement is very reusable. Old cement can be ground up and reused quite readily. sorry but the question is quite open ended. That is unless your teacher specified an answer in class and you just didn't catch it!
Q:what is the cement types made in the industry?which is the more used all over world?
types of cement varry from a place to the other , they are basically 12 . The most common is the Ordinary Portland Cement
Q:Which type of cement would i use for a mud floor, & what cement to sand ratio should i use?
portland cement, 3 parts gravel 2 parts sand 1 part cement just enough water to make a paste
Q:What is/Was Water Putty and Portland cement used for/are?
Water putty is a putty that will harden even if it is underwater. You would usually use it repairs under water. Pools, pipes, ETC Portland cement is used to make concrete. Concrete usually has the cement and some type of hard particles ( sand, small rocks, or both)
Q:Adhesive for laminate onto masonite? Besides Contact Cement.?
Laminate Contact Cement
Q:what is the ratio for the cement to install cement block; sand, cement . and mortor creme?
There is a difference in the sand for motar that the sand you use for pouring cement such as a slab. The motar sand is very, very fine and for the cement you can just use builders sand. I recommend a 3 to 1 mixture. Not sure what you mean by motar creme unless you are referring to a latex additive. I would absolutely recommend using the additive, it makes the motar more of an adhesive and also makes it repel moisture so it will last years longer especially in colder climates.
Q:Why is my Portland Cement gray?
Don't let those others lead you astray. Unless you can mix the patching concrete to the exact same formula as the original mix, you will get color variation. Methinks we may have been a little overzealous with the cement in the patching batch, yes? If you have put more cement into it than the original lot, then, alas, your patches WILL be darker than the rest. Ain't Mother Nature amazing!
Q:Installing cement board...?
Are you saying there's 2 layers of boards on top of the floor joists? If yes then removing the top layer would be the way to go if the bottom sub-floor layer is strong enough to not be springy under concentrated loads or if you can beef it up by installing bridging underneath between the joists. If the sub-floor is the only layer then you'd not want to remove that since the structural integrity of the house would be affected and the cement board wouldn't be properly supported.
Q:Using rubber cement for frisket?
I don't know for sure. It's pretty harsh stuff. And most papers don't stand up well to having adhesives removed from them. As another possibility, 3M have a range of masking tapes for interior decoration (painting) that might suit you better. Imagine the sticky stuff from post it notes, but a little stickier, and in tape form. Just as easy to remove, though. And they claim their tapes don't leave marks or residue. I've seen them at hardware stores, but art suppliers might stock them too. Good luck finding something.
