Method for processing recovered wax

Abstract

This invention describes a process for treating recovered wax, comprising the steps of: adding water whose amount is at least 10% that of the recovered wax into a treating barrel, and heating the water to higher than or erqual to 85 deg.C and lower than100 deg.C; adding the recovered wax into the barrel, keeping the recovered wax in liquid state and stirring in order that the impurities in the wax combine with water and precipitate to the bottom of the treating barrel due to a higher specific weight than the wax; discharging the precipitant, and vacuum-pumping and heating the treating barrel so that the residual water is vaporized and discharged. The process can recover pure wax within a short time, thus shortening the operation time and reducing the cost, and can increase the purify of the recovered wax.

Description

Technical field: [0001] The invention relates to a treatment method for recovering wax. Background technique: [0002] With the advancement of industrial technology, new products are constantly being developed to provide people with more convenient use. As far as the manufacture of various items is concerned, there are various methods depending on the product and material, among them, such as gold ornaments, For the manufacture of golf heads and other articles, it must first be made into a wax mold, and then the outer surface of the wax mold should be covered with water-resistant materials. After drying, it should be dewaxed to obtain the finished product. For dewaxing, it is 5kg / cm 2 High-temperature, high-pressure steam to dissolve the wax pattern, so the recovered wax will naturally contain moisture and impurities that are peeled off by water-resistant materials. When the cost of the wax is high, the wax after dewaxing needs to be recycled. Some systems The recycled wax ...

[0002] With the advancement of industrial technology, new products are constantly being developed to provide people with more convenient use. As far as the manufacture of various items is concerned, there are various methods depending on the product and material, among them, such as gold ornaments, For the manufacture of golf heads and other articles, it must first be made into a wax mold, and then the outer surface of the wax mold should be covered with water-resistant materials. After drying, it should be dewaxed to obtain the finished product. For dewaxing, it is 5kg / cm 2 High-temperature, high-pressure steam to dissolve the wax pattern, so the recovered wax will naturally contain moisture and impurities that are peeled off by water-resistant materials. When the cost of the wax is high, the wax after dewaxing needs to be recycled. Some systems The recycled wax is directly processed. When making wax patterns, since water and wax do not mix, the recycled wax with high water content is placed in front of the wax spraying machine, so it is necessary to carry out empty spraying action first. The quantity of this empty spraying As much as 1 / 5 to 1 / 4, not only forms unnecessary waste, but also, because the remaining recycled wax still contains moisture and impurities, it will not only cause voids in the finished wax model, but also the products made of the wax model It will also form gaps or burrs, which will lead to an increase in subsequent grinding and finishing man-hours

[0003] In order to solve the lack of direct use of the above-mentioned recycled wax, there are people such as figure 1 In general, pour the recovered wax into a recovery bucket, and then heat it up to 90°C to dissolve the wax into a liquid state without boiling the water. Using the property that the water and wax will not dissolve, the water will naturally precipitate At the bottom of the recovery bucket, the waiting time for this natural precipitation is as high as 20 hours, and then the water of the precipitation is drained, and then the remaining recovered wax is poured into the wax sprayer for use. Although this method can drain most of the water However, the processing time is too long, and this natural precipitation method cannot filter out water, that is to say, the recycled wax cannot be completely free of water, and it still contains impurities that are resistant to peeling off of water, so that although the recycled wax is more directly used Good, but the residual water and impurities will still cause the above-mentioned disadvantages when making wax patterns and products with wax patterns, so it is really necessary to improve
