Q: Why should the new resin be disposed of? How do we deal with it?: Specific treatment methods include:(1) treated with salt water;Salt water solution 10%, approximately equal to the volume of resin treated 2 times to soak for 20 hours or more, and then put salt water, with water rinse, drain water with yellow. If the impurities and fine resin powder should be rinsed clean.(2) treated with dilute hydrochloric acidWith 2%, a 5% concentration of HCl solution, about equal to 2 times the volume of resin treated, soaked for more than 4 hours, and then put the acid solution, washed with water until neutral.(3) treated with dilute sodium hydroxide solution, with 4% NaOH solution, approximately equal to 2 times the volume of resin treated, soaked for 4 hours, and then put lye, washed with water until neutral.

Q: I am replacing several pieces of galvanized water pipes leading to my house. Several people have told me to use teflon tape and pipe dope on the threads while others have said only pipe dope. The pipe dope I am using has a teflon lubricant. I noticed on one fitting where I tried using both, then had to take it back apart, that with the dope on it, the tape wouldn't hold its position like it does by itself. Instead, the pipe just seems to push the tape up as it is screwed on. That makes me lean more towards the dope by itself. Also, the directions on the bottle say to apply the dope to the bare threads. What should I do?: FIrstly i think you mean question 81, and secondly you rub the mouse up and down the rod really fast

Q: It's about 48 x 19-20 inches and 3/4inch thick. I found a 9oz mix thats only $11 but im pretty sure that's not enough for the whole board. And i've read that i should thin out the resin, is that correct? If so, can regular sink water be used to thin it out? So should i just get the 9oz or buy a quart?: NO POSION as it is cruel and against the law as other protected species may eat the poisoned birds. Such as birds of prey and cats etc Easiest solution is to hang plain tin pie tins from a string around the area for awhile and they will avoid it. They hate it. If for some reason that does not work which it should get a fake owl and sit it there the motion detector ones that move their heads are the best.

Q: Explain the stoichiometry involved in blowing air on the base of a dwindling campfire to keep the coals burning. thank you(:: I think you can encase a small fish in casting resin. Complete frogs have been found in amber resin which is nothing more than tree sap. Here are pictures of several species in amber resin which are over 40 million years old. /EdResources/

Q: Please help before I freeze hahah: Uhm, I never wore one on my moped, but if they are being stupid about it, explain you have lights, so cars will see you, or just take it off when you get down the road, then put it on when you're near your house again.

Q: Hi I was wondering if it's possible to inflict serious damage on my Mini's undercarriage of I scratched it on a speed bump. I tried to park in this spot that was next to a speed bump exiting it When I first parked i turned left to enter it and i didn't feel or hear anything but when I had to leave the car went over the speed bump so the speed bump was under the middle of the car and I heard a loud scraping noise Did I do serious damage or did I scratch it? Serious answers please! thanks: Why would you buy 22 miles of copper and hook it onto a helium balloon i would say you would definately get into some trouble if that were to affect a plane. You would probably receive a felony charge. My advice, don't try anything you will regret.

Q: Make leather shoes, polyurethane resin glue: If you need to make a polyester resin, then you can definitely tell you: This is a trade secret, it is impossible to tell you.

Q: I guess that might be a safety feature. Anyway, I put the battery back in but now the alarm emits small beeps like every two minutes or so. Why?: IF the polymer has been baked rigid to make a reusable mold, if the release works you may still have trouble getting the casting out unless it is shaped exactly right. A soft latex or silicone rubber mold (latex backed by plaster) may work better for a limited run - each of these from a modeling clay original - how will you make the polymer clay (not really modelling) mold - from a model or by hand shaping it.

Q: I want to build a brick kiln outside for firing clay sculptures..will that work?: frequently the decreased weight which improves the miles according to gallon gas performance. that is because of the fact lots of the fuselage textile is created from carbon fibers, that's lighter than the former alumin-titanium shape, and each fuselage would be produced as a single piece. This removes the will for hundreds ribbits and fastners, consequently extra reducing weight.
