Abstract
The invention relates to a glass magnesium board scrap recovery processing method and is characterized in that the recovery processing method comprises the following steps: a, crushing glass magnesium board scrap produced during the production process; b, adding the crushed scrap into a hydrochloric acid dissolving tank, uniformly stirring and dissolving; and c, filtering a solution after a reaction with hydrochloric acid and clarifying in a clarification tank to obtain a solution suitable for production. The method is simple to operate. By the method, consumption of raw materials can be reduced, and adverse effect of solid waste treatment on the environment also can be decreased. Energy is saved, the environment is protected, and production cost can be reduced effectively.
Description
Technical field
The present invention relates to the technical field of waste recovery, specifically a kind of glass magnesium sheet material waste recovery treatment process, the character particularly utilizing this waste material can be dissolved in technical hydrochloric acid carries out the method for recycling.
Background technology
At present, the enterprise of domestic production magnesite product is difficult to win number, also simultaneously with waste materials such as a large amount of scrap stock in production process.If directly abandoned by these waste materials, not only cause the pollution of environment, increase processing cost, be also the huge waste to resource simultaneously.And current most enterprises adopt and are pulverized by available waste material, then direct crushed material is added in raw material for the production of.The drawback done like this is that tool is not active due to crushed material, and for ensureing that sheet material quality addition is not easily too much, waste material is fully recycled by difficulty or ease; This addition means directly causes density of material to increase simultaneously, and quality declines.
Summary of the invention
The object of the present invention is to provide a kind of glass magnesium sheet material waste recovery treatment process of improvement, it can overcome waste material in prior art and can not fully recycle, and slug detect causes density of material to increase, the some shortcomings that quality declines.
To achieve these goals, technical scheme of the present invention is: a kind of glass magnesium sheet material waste recovery treatment process, is characterized in that: described recovery and treatment method comprises the steps: a, pulverized by the glass magnesium sheet material waste material produced in production process; B, the waste material after pulverizing is added in dissolving with hydrochloric acid pond and dissolves after uniform stirring; C by with hydrochloric acid reaction after solution filter after put into settling pond and clarify, the solution being applicable to producing can be obtained after clarification.
During use, the present invention utilizes technical hydrochloric acid the discarded glass magnesium PLASTIC LAMINATED (scrap stock, substandard products) produced in production process to be dissolved, and obtains the solution that can be reused for production.First waste material is pulverized, then crushed material is dropped in the bath holding technical hydrochloric acid and dissolve, thus obtain the solution that can be applicable to production.The method is simple to operate, can cut down the consumption of raw materials, and can reduce again the detrimentally affect that solid waste process causes to environment, energy-conserving and environment-protective, can effectively reduce production cost simultaneously.
Embodiment:
Below in conjunction with embodiment, the invention will be further described.
A kind of glass magnesium sheet material waste recovery treatment process of the present invention, its difference with the prior art is: described recovery and treatment method comprises the steps: a, pulverized by the glass magnesium sheet material waste material produced in production process; B, the waste material after pulverizing is added in dissolving with hydrochloric acid pond and dissolves after uniform stirring; C by with hydrochloric acid reaction after solution filter after put into settling pond and clarify, the solution being applicable to producing can be obtained after clarification.
In a step, glass magnesium sheet material waste material employing pulverizer processing powder is broken to particle or powder that particle diameter is less than 5mm.
In b step, adopt concentration of hydrochloric acid to be the amount of 31% input crushed material and the weight percent of hydrochloric acid in dissolving with hydrochloric acid pond to be: 1:1.3-1.6, the time is 7 ~ 8 hours.Hydrochloric acid pond adopts cement pit to make, and the surface of cement pit is provided with machine acid-proof material clad can.
In step c, filter employing 80 eye mesh screen and filter, solution remains in settling pond and clarifies more than 4 hours.
In force; first waste material processing powder is broken to particle or powder that particle diameter is less than 5mm; then according to the amount of technical hydrochloric acid in dissolving tank; the weight ratio of crushed material and hydrochloric acid takes the crushed material of suitable weight by 1:1.5; and crushed material is slowly joined in dissolving tank, stir and make it fully react.Place for some time, after it reacts completely, to be filled in settling pond by solution with 80 screen clothes and to clarify, settling time, at least more than 4 hours, uses when waiting until production.
Test method:
Traditionally glass magnesium PLASTIC LAMINATED production technology, use the saltwater brine of degree Beaume 25 respectively, test sample is made by weight ratio 1:1-1.1 of magnesium oxide and saltwater brine, wherein sample 1 saltwater brine adopts starting material preparation, sample 2 saltwater brine adopts method of the present invention to be prepared by waste recovery mode, and sample 3 adopts that directly to add weight ratio in sample 1 scheme be 30% feed back powder.
Its partial properties correlation data is in table 1.
Table 1 embodiment performance comparison
By relatively finding out, the method for this waste recovery, uses with the solution property made of raw material about the same in actual production, can raw material be replaced and not affect plate property, and whole operating process is simple, cost is low, is a kind of well waste material recovery method.
