- Q:How many kinds of epoxy resin are there?What are the characteristics of each?
- This kind of alicyclic epoxy resin epoxy resin is cyclic olefin by grease prepared by epoxidation of double bond, their molecular structure and two phenol propane epoxy resin and epoxy resin have very big difference, the former is directly connected to the lipid epoxy ring, epoxy and the latter is connected in the benzene nucleus or aliphatic hydrocarbon with epoxy propyl ether. Alicyclic epoxy resin cured group has the following characteristics: compression and tensile strength were higher; the long run the storm can still maintain good mechanical properties at high temperature; the arc resistance, UV resistance and ageing resistance and weather resistance is good.
- Q:I NEED HELP I CAN'T DO PHYSICS FOR MY LIFE
- Well it all depends on if the tranny or any part of the drivetrain actually made contact with the ground. If it was strictly all suspension, then no it should not cause any tranny problems.
- Q:Please help before I freeze hahah
- WOW i cant stop laughin try to convince you rents to let you wear something else!
- Q:Dispersion involves separating of wavelengths by their amplitude.TrueFalse Which of the following is the best definition of diffraction?movement of a wave through solid materialsa wave being blocked by obstacles in its patha wave bending when it encounters a temperature differencea wave changing directions or moving around something in its pathIf the walls of an auditorium are highly reflective of sound waves, what are you likely to have?lots of reverberationmore high-pitch soundhigher sound qualitysofter noiseWhat is the frequency of a wave that has a period of vibration of 2 seconds?5 Hz2 Hz0.5 Hz10 Hz
- Water! Water purely exists in the steadiness between warm and chilly. Water is a condensate molecule, and isn't any longer even a area, because it can't exist under the molecular point. chilly makes water convey mutually, and warmth makes water advance and seperate. for this reason water can purely exist as a molecule the place the steadiness between warm and chilly is optimum. if too chilly, it freezes, if too warm it evaporates, yet while balanced it flows. the final of all worlds. while contaminated, only warmth, and then relax to reform.
- Q:What's the general price of resin lenses?
- Often hundreds of dollars a pair of resin lenses, why often wear only the year, on the lens fluff? Experts point out that cleaning resin lenses should be washed and should not be wiped.Glasses lenses are generally more than two kinds of glass lenses and optical resin lenses. The former high hardness, good abrasion resistance, general quality and the parameters do not change over time, but the glass lens in impact resistance and weight slightly inferior to resin lenses. The latter is light and has better impact resistance than glass, but it has lower surface hardness and is easier to abrade.
- Q:I just bought a treadmill and when it's running the vibrations bother the landlord in the apartment below me. Would putting a heavy blanket under the treadmill stop or dull the vibrations?
- You can just unbuckle the chin strap and slide the helmet up real quick and get a drink or just squirt the water through the cage. I played roller for about five years before i went to ice and i play juniors now. And yeah i also don't recommend the full face shields, there a pain.
- Q:I've been working for this company for a month and a half I found out this weekend that i'm pregnant.I've made friends at this new job so I wanted to tell them the exciting news.So yesterday (monday) everyone knew and were very excited and I had a great day.Then today (tuesday) I walk in and I get fired. I feel like I got fired because I'm pregnant now.Is this a law suit waiting to happen?
- A great deal of the dust one finds in a home is comprised of dead skin cells. Other dust components would be fibers lost from fabrics such as clothing, carpets, furniture etc. Other sources would include pollen, mold spores and other bits of nature. Astrobuf
- Q:describe the safety aspects of dealing with plastic type bumpers which may contain floureolastimers and which may have been or could be effected by heat
- Get the installation instructions and work backwards. Be extra careful as you can cause a lot of damage if you don't do this the right way. If any wires were cut and need to be re-connected, solder them back together and then cover with heat shrink tubing. The good thing is that you will need to know all of this to install the alarm in your car, so it is not wasted time.
- Q:i dont have the original remote to my tv but i have the sony d900 speaker system remote that controls my tv..how do i remove the little screen/box?
- If you are just starting, a 1:1 epoxy resin will be your best bet. There are several manufacturers, they are all basically the same, clear, and cost about $15 for an 8 oz bottle of resin and an 8 oz bottle of activator. You can find it at craft stores, hobby stores, and hardware stores. Envirotex Lite is one brand name I can think of. Start with that. If you find you are making LOTS of cabochons, you can then start buying the stuff in bulk. A gallon of resin (1/2 gal each of resin and activators) runs about $50-60 online, plus shipping.
- Q:I've seen a lot of motorcycle visors that are a material that I would like but I'm trying to create a helmet that covers my whole face for a costume. I've been told cutting small strips of automotive tint won't work. I've also discovered that space suits use and electroplating process to deposit gold onto the visor, but my material is acrylic. I'd like to know how one would create a mirrored surface with any technique or even places that do that process for you. This is the helmet in question.
- both are pretty cool. i would take the first one
