Problems solved by technology

The patented technical solution adopts the method of electric heating, and uses water to dilute the useless substances in the recycled materials. Although this method removes other impurities in the recycled materials, it does not affect the particulate impurities and alkaline in the recycled materials. Substances are not effectively removed

Embodiment 1

[0024] A recycling process for paraffin-resin molding materials,

[0025] A), adding hydrochloric acid HCL of 2% of the weight of the recycled material to the recycled material; the pH value of the hydrochloric acid HCL is 1;

[0026] B), add 30% water of recycled material weight to recycled material;

[0027] C), feed steam into the recovered material added with water and hydrochloric acid to make the recovered material boil for 10 minutes;

[0028] D), the recovered material obtained in step C) is allowed to stand still for at least 20 minutes; and the temperature is kept at 80°C to obtain a mixed solution; the obtained mixed solution is filtered through a 150-mesh sieve;

[0029] E) Cool the mixed liquid obtained in step D) naturally, let off the acid water, and obtain the finished wax plate.

Embodiment 2

[0031] A recycling process for paraffin-resin molding materials,

[0032] A), adding hydrochloric acid HCL of 2% of the weight of the recycled material to the recycled material; the pH value of the hydrochloric acid HCL is 1;

[0033] B), add 30% water of recycled material weight to recycled material;

[0034] C), feed steam into the recovered material added with water and hydrochloric acid to make the recovered material boil for 10 minutes;

[0035] D), the recovered material obtained in step C) is allowed to stand still for at least 20 minutes; and the temperature is kept at 80°C to obtain a mixed solution; the obtained mixed solution is filtered through a 150-mesh sieve;

[0036] E) Naturally cool the mixed liquid obtained in step D) to normal temperature, let off the acid water, and obtain the finished wax plate or wax liquid.

Embodiment 3

[0038] A recycling process for paraffin-resin molding materials,

[0039] A), adding hydrochloric acid HCL of 4% of the weight of the recycled material to the recycled material; the pH value of the hydrochloric acid HCL is 1.5;

[0040] B), add 35% water of recycled material weight to recycled material;

[0041] C), feed steam into the recovered material added with water and hydrochloric acid to make the recovered material boil for 15 minutes;

[0042] D), the reclaimed material obtained in step C) is allowed to stand still for at least 20 minutes; and the temperature is kept at 90°C to obtain a mixed solution; the obtained mixed solution is filtered through a 150-mesh sieve;

[0043] E) Naturally cool the mixed liquid obtained in step D) to 50°C, let off the acid water, and obtain the finished wax liquid.

Abstract

The invention discloses a technology for recycling a paraffin-resin mold material and particularly belongs to a technology for recycling a mold material of a precise mould. The technology for recycling the paraffin-resin mold material performs full reaction on hydrochloric acid and an alkali substance waterglass sodium silicate in a recycled paraffin-resin mold material to obtain a finished product in a steam heating way. The technology for recycling the paraffin-resin mold material has the advantages of simple process, convenience in operation, capability of effectively removing the alkali substance and granular impurities from the recycled paraffin-resin mold material, and reusability of the recycled paraffin-resin mold material.

Description

technical field [0001] The invention discloses a recycling process for paraffin-resin mold materials, in particular, it belongs to the mold material recycling technology for precision moulds. Background technique [0002] In the field of investment casting, using wax as a raw material is more and more widely used, but how to recycle and utilize the used wax material is a problem that manufacturers are eager to solve. [0003] Subsequently, a patented technical solution named a recovery of wax patterns in investment casting and its equipment appeared. Its application number is 201010197127.9, its application date is June 8, 2010, and its publication date is December 14, 2011. The technical scheme of this patent includes the following steps: providing recovery liquid; providing a working tank that can accommodate the recovery liquid; placing the casting cavity containing the casting wax pattern in the working tank; Recover the liquid for heating; provide a recovery device to ...
