Abstract
The invention discloses a separating method of carborundum particles on a surface of a diamond wire. The separating method comprises the following steps: a step I of adding 100ml of concentrated nitric acid and 15ml of concentrated hydrochloric acid into a beaker contained with the diamond wire, sufficiently stirring; a step II of heating up the beaker while stirring until the diamond wire is completely dissolved in liquor; and a step III of washing the materials in the beaker by using clear water, and drying after washing to obtain separated carborundum particles. The separating method disclosed by the invention has higher operability, repeatability and reproducibility. According to the separating method disclosed by the invention, a diamond wire base material and a coating on the carborundum surface can be rapidly dissolved by adopting a chemical reagent; meanwhile, the chemical reagent does not react with the carborundum, so that the obtained carborundum particles are full, complete and free of residual steel wires and coating. Besides, the separating method is simple to operate, low in cost and convenient for popularization.
Description
Technical field
The present invention relates to the separation method of a kind of diamond wire surface particles of silicon carbide.
Background technology
Diamond wire is the steel wire that a kind of surface is coated with emery, it is generally used for the article of the materials such as cutting sapphire, the emery quantity on diamond wire surface directly affects the effect of cutting, required according to technology, need to measure the quantity of diamond wire surface particles of silicon carbide.
At present, the separation method associative operation of diamond wire surface particles of silicon carbide does not have unified operation standard, thereby cannot guarantee that isolated emery meets the requirement detecting.Therefore a kind of method of operating is simple, the exploitation of the separation method of diamond wire thoroughly diamond wire separated with emery surface particles of silicon carbide is necessary.
Summary of the invention
Technical matters to be solved by this invention is to provide the separation method of a kind of diamond wire surface particles of silicon carbide, and this separation method makes the particles of silicon carbide after separation surperficial without remaining coating, noresidue steel wire.
For addressing the above problem, the technology used in the present invention problem is:
A separation method for diamond wire surface particles of silicon carbide, comprises the steps:
Step 1, adds 100ml red fuming nitric acid (RFNA) and 15ml concentrated hydrochloric acid successively to filling in the beaker of diamond wire, fully stirs;
Step 2, heats beaker while stirring, until diamond wire is dissolved in solution completely;
Step 3, washs with clear water the material in beaker, after washing, dries and can obtain isolated particles of silicon carbide again.
As preferably, in step 1, the length of diamond wire is 3～5cm.
As preferably, in step 2, the temperature of heating is 280～320 ℃.
As preferably, in step 3, described drying unit is baking oven, and described bake out temperature is 100～120 ℃.
As preferably, the particle diameter of described particles of silicon carbide is 100um.
Beneficial effect: than prior art, separation method of the present invention has very high operability, repeatability and reproducibility, this method adopts chemical reagent fast the coating on diamond wire matrix and emery surface to be dissolved, this chemical reagent does not but react with emery simultaneously, thereby make the particles of silicon carbide that obtains complete, complete, without remaining steel wire and coating, separation method of the present invention has conveniently obtained surface clean, without the residual particles of silicon carbide of steel wire, by the particles of silicon carbide obtaining by its quantity of microscopic examination and shape, thereby can show that emery is used the degree of wear of front and back, the inventive method is simple to operate, cost is low, be convenient to promote.
Embodiment
A separation method for diamond wire surface particles of silicon carbide, comprises the steps:
Step 1, by 10 long be that the diamond wire of 3～5cm is placed in 400ml beaker, in beaker, add successively 100ml red fuming nitric acid (RFNA) and 15ml concentrated hydrochloric acid, with glass bar, the material in beaker is fully stirred;
Step 2, heats beaker while stirring, and the temperature of heating is 280～320 ℃, until diamond wire is dissolved in liquid completely;
Step 3, washs with clear water the material in beaker, washs after 3～5 times, and the material after washing is placed in baking oven, and oven temperature is 100～120 ℃, and baking time is that 4～6h can obtain isolated particles of silicon carbide.Resulting particles of silicon carbide particle diameter is 100um.
Obviously, above-described embodiment is only for example of the present invention is clearly described, and is not the restriction to embodiments of the present invention.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all embodiments.And these belong to apparent variation that spirit of the present invention extended out or change still among protection scope of the present invention.The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
