Q:The difference between gum and resin
Many trees secrete their body fluids to protect and heal wounds when their bark is injured. This body fluid can be divided into two broad categories, one is hydrophilic colloid, such as Arabia gum, gum and many other gum. The other one is hydrophobic colloid gum, such as dammar resin and rosin. The former is usually acidic macromolecules, polysaccharides, soluble in or swelling in water; while the latter is a high polymer, generally soluble only in organic solvents.
Q:car bumper?
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:How do you fix a bad day (or at least make it better)?
Have fun! (Trust Rio Grande's products, they're the best jewelry supply site!)
Q:What kind of resin is AC resin (AC as raw material for the production of glasses lenses)?
AC is the abbreviation of acrylic ester Acrylate. The AC resin used here is made of polymethyl methacrylate.
Q:how fast over a speed bump will ruin your vehicle struts on the front end?
The process of amber formation from tree resin takes millions of years for the resin to harden into amber, different publications say some ten millions. Molecular polymerization caused by pressure and heat transforms the resin first into copal and then over time through the evaporation of turpenes it is transformed into amber. This process is called succinosis. The sources - inter alia - show details of chemical and physical processes.
Q:Ask for some introduction of thermosetting materials, it is best to have advantages and disadvantages are issued
Chemical resistance: the ether group, benzene ring and fatty hydroxyl group in the curing system are not susceptible to acid and alkali corrosion. In the sea water, oil, kerosene, 10%H2SO4, 10%HCl, 10%HAc, 10%NH3, 10%H3PO4 and 30%Na2CO3 can be used in two years; and in the 50%H2SO4 and 10%HNO3 soaking at room temperature for half a year; 10%NaOH (100 DEG C) for a month, performance remains unchanged.
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:Why pretreatment of resins?
A resin is loaded into a container, the container for backwashing resin with small flow operation, to remove residual impurities mixed material and manufacturing process of the reaction did not participate in the resin production process in the backwashing drainage to clear.B, soak the resin with 5% HCI solution for 4 hours, then rinse the water to neutral. The purpose of acid treatment is to remove inorganic impurities in the resin.C, take temporary take over method, the Yang bed pretreatment into the alkali pipe connection, with 2% NaOH solution soak resin for 4 hours, release the lye, wash the resin to the drainage, close to neutral. The alkali treatment is mainly to get rid of the organic matter in the resin.D, after the above treatment, the original regeneration system will be recovered, and the normal regeneration of the bed should be carried out by the large backwashing and regeneration dose, and then it can be put into operation.Precautions for pretreatment:A and new resin should be prevented from dehydration before pretreatment, or they can not be treated directly. The new resin without normal dehydration can be washed directly with water until the water is colorless and hardness free.B, the volume of soaking liquid generally take 2 times the volume of resin, in order to fully soak the resin.C, for a small amount of resin replacement, can be carried out in the external anti-corrosion containers, should avoid the pretreatment of new resin directly filled in the exchanger.D, for the new resin pretreatment of the exchanger, before regeneration must be large backwash, and large backwash before should be small backwash.
Q:What was the incident that took place in arkansas?
The problem with Gonzales firings is this. They are not allowed to fire them for 'political' reasons. Gonzales testified before Congress, under oath, that they were fired for poor performance. It was later discovered that Gonzales lied to Congress, which is a felony, and it appears it goes even deeper. From the evidence so far it looks like they were fired for refusing to dropping criminal investigations against corrupt Republicans. If that is true then Obstruction of Justice charges could also be filed (also a felony). Neither of these charges are minor and if found to be true should be prosecuted.
Q:What is the use of self - hardening furan resin? Where should I use it?
Furan resin refers to the furan ring with furfuryl alcohol and furfural resin as general raw material production, which under the action of the acid curing into insoluble and infusible solids, a variety of furan resin, resin furfural, furfural acetone resin, furfural acetone formaldehyde resin etc..
