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: stop dog from pooping in backyard cement walkway where kids come and go we try to show him where theres a corner of dirt by our trash cans , he went there once only
- I'm sorry, after all the 'my dog poops all over the house' questions, this just strikes me as hilarious! Maybe some of those people that can't seem to get their dog to poop in the backyard at all can help you out! LMAO! Seriously though, you were doing the right thing with taking her on a leash and using praise and treats, it's just going to take longer to really get the dog to understand that this is where it needs to go. Just give it more time. When the dog starts to lead you to that spot, you'll know she has it down and doesn't need the leash anymore.
- Q: How do you pronounce cement?
- cement.....when I lived in Texas they would call it CEEE ment.
- Q: is is located in looc, malabuyoc, cebu, philippines .. it is under the yuchengco group of companies .
- I don't understand your question, what is it you are trying to ask?
- Q: What is the most common cement used in concrete?
- its called portland cement
- Q: Okay, I have some 4quot;PVC to 2quot;PVC reducer, a 4quot; PVC tank/endcap, and a ball valve. It is going to be under a lot of pressure (70-100PSI), this is my first time bonding PVC so what should i do in steps? I heard PVC Primer then Cement it together. Anything else?
- Make sure your reducer (as well as other parts) are NOT Drain/Waste/Vent, as they are not rated for that much pressure. The main difference is how deep the socket(female) is. If it is about 1/2 inch on the 2 inch side, it won't hold that much pressure. 1/4 turn is all that's needed, and hold for about 15 seconds. Wipe off any excess. It doesn't hurt anything, the glue bonds by melting the PVC, and it will reharden.
- Q: I have decided to cement the outside of my house in a stucco design. What materials will I need?
- First, I think you need to put a special wrap on your existing siding. I am not sure what this would be; ask at your home repair store. Then you have to install a railing on the bottom of the design as a guide and also to keep the cement in a straight edge and also from sliding. I watched a guy cement his house and he constantly put little strips of mesh on the area he was working and slopped more cement over it. I would study up on this first before I begin on a project like this. I think the major obstacle is getting the cement to stick on the surface, it would be discouraging if you cemented a section and the next day it was on the ground in one whole piece.
- Q: I have two uses:1. rock climbing shoes - (a) some early signs of de-lamination of toe sole from the rand; (b) side rand starting to have wear/scraped off2. trekking shoes (Teva with 'Spider Rubber')- front part of sole separated halfway. would like to maintain its waterproof properties, so having it sewn is not an optionwhich would provide better adhesiveness? Both rubbers are relatively soft sticky since these are special grip shoes. No shoe repair shop in my country has materials skills to fix rock climbing shoes. And normal contact cement won't hold the fix for the shoes' use. *I think 5.10 had a repair kit before using Barge Cement (yellow tube, instead of the blue one), but the reviews say that it didn't quite work.any other glue brands / tips? thanks!
- Barge Shoe Glue
- Q: Is the cement industry in the stock a separate plate? Or part of the other plate?
- The cement industry is still a separate plate, building materials (bi1133) cement more, of course, all the plates are cross each other, you can choose the custom plate, the cement alone together to analyze.

- Q: It was fine for the first 4 winters and then we had a real hard freeze that lasted for a few weeks, the fish survived but the pond leaks now. I tried draining it and patching but it didn't hold. Is there a simple solution?
- Dap makes Liquid Cement Crack Filler. It is an epoxy that actually glues cement back together. It comes in an easy to use quart squirt bottle. I used it when our fountain froze and chunks of cement broke off. Two winters have gone by, and we still have a water tight repair. You can find it at a Home Center like Lowes or Home Depot.
