Q:why do you need safety glasses for the enzyme test ?
5 last night but tonight a 6! it is so cold!
Q:What is the nature of the resin? What are they?
Resins are normally considered as normal metabolites or secretions of plant tissues, often in the ducts of ducts or ducts, especially in the heartwood of perennial woody plants, in combination with volatile oils.
Q:I'd like to use talcum powder as fiberglass resin filler. I don't know what specifications
Glass steel products general filling material 400 mesh and 800 collocation is feasible, it is fine, coarse not too thick (easy to precipitate), a filling requirement is not high enough, more personal experience for your reference.
Q:What are electric guitar (Locking) tuner's and how do they work?
It's more by choice or need (because of an injury) but there are no rules at this time saying there has to be any protection but the actual helmet. I wouldn't be surprised if that changes someday, though.
Q:What is the resin PP material?
Copolymer type PP material has lower thermal distortion temperature (100C), low transparency, low gloss and low rigidity, but has stronger impact strength. The strength of PP increases with the increase of ethylene content. PP VEKA softening temperature is 150C. Because of its high crystallinity, the surface stiffness and scratch resistance of this material are very good.
Q:My Dad ripped the metal around my ignition lock/key cylinder. What is that part called?
If you're talking about Rs3 its melee armour. The combat triangle actually takes into action with how the things are in RS at this time. So Rune for f2p is my answer.
Q:is it called a .!!??
One doesn't exsist. For a product to be food safe it needs to cure (or 'be fired') at a hugh temp so that chemicals don't leech in to hot or acidic food.
Q:Survey; What's a list of items you would bring in a natural disaster with you?
According to the Material Safety Data Sheet (MSDS), the resins, hardners and accelerators are not cancer causing agents. The vapors and skin contact can cause severe eye or skin irritation or lung irritation. Proper ventilation should take care of that problem. As always, it is a good idea to wear eye protection of some sort. I have used the premixed (like a large syringe) stuff and the stuff where you buy the two separate cans. The only time I had a problem, is I got it on my hands and wasn't wearing latex gloves.
Q:On the game, Zelda Twillight Princess, how do I get the shield?
I would think you need a flexible mould for polyester resin. I think a steel bowl would be too rigid to allow for removal of the cast, even with release agent, you'll juct end up chipping or cracking your cast. A rubber moulding compound like vinamold or silicone would be best. You'll probably need a two-part or even three-part mould if you want a hollow bowl shape rather than just a solid hemisphere of resin. If that's what you're looking for, a cheap mold could be made by cutting a rubber ball in half and filling it with resin.
Q:Another fire alarm issue?
:) I have never had to decide that as i have never seen an out of order fire hydrant. Call and ask the fire dept. they will enjoy the challenge. :)
