Abstract
The invention discloses a stearic acid wax material recovering processing technology. The technology comprises the following steps: checking whether a processing tank has water leakage and wax leakage phenomena or not, burdening water and a wax material, adding the obtained mixture to the processing tank, heating, adding hydrochloric acid or sulfuric acid when the wax material is boiling, discarding acid water, and detecting the pH value of the obtained wax liquid to obtain a qualified wax liquid. The processing technology can be used to well recover the wax liquid and process the qualified wax liquid to a brown or yellow transparent wax liquid.
Description
Technical field
The invention belongs to casting waterglass technical field, particularly a kind of stearic acid wax material recovery processing technique.
Background technology
In casting waterglass process, can relate to a lot of waste material, cause great waste, improve production cost, waste resource, existing recovery method can not thoroughly be recycled, and utilization rate is not high.
Summary of the invention
The invention provides a kind of stearic acid wax material recovery processing technique.
Technical scheme of the present invention is: a kind of stearic acid wax material recovery processing technique, is characterized in that, comprise the following steps:
(1) whether check processing groove leaks, leaks wax;
(2) water to be processed and wax material are prepared respectively and add in treatment trough, be heated to boiling, keep fluidized state 45-60 minute, temperature controls at 95-105 DEG C, and wherein, the ratio of wax material and water is 3:1;
(3) under wax material fluidized state, slowly add hydrochloric acid or sulfuric acid, continue 45-90 minute;
(4) open after treatment trough valve bleeds off sour water, add appropriate water and be heated to the 10-15 minute that seethes with excitement again, 2-3 time repeatedly, the pH value of measurement sour water, makes pH value be 6-7;
(5) wax liquid qualified after, through being furnished with being pumped in stationary tub of screen pack.
Preferably, hydrochloric acid is added in wax material in described step (three).
Preferably, described step (four) if in when the pH value of sour water is less than 6-7 after 2-3 time repeatedly, in treatment trough, add industrial Na (OH), then survey pH value.
Preferably, in described step (five), qualified wax liquid just can enter next process in static more than 2 hours in stationary tub.
Beneficial effect of the present invention: processing method energy of the present invention well recycling wax liquid, processing qualified wax liquid is brown or yellow transparent shape.
Detailed description of the invention
Embodiment provided by the invention is described in further detail:
A kind of stearic acid wax material recovery processing technique, comprises the following steps:
(1) whether check processing groove leaks, leaks wax, has problem to process in time;
(2) water to be processed and wax material are prepared respectively and add in treatment trough, be heated to boiling, keep fluidized state 45-60 minute, temperature controls at 95-105 DEG C, and wherein, the ratio of wax material and water is 3:1;
(3) under wax material fluidized state, slowly add hydrochloric acid or sulfuric acid, continue 45-90 minute;
(4) open after treatment trough valve bleeds off sour water, add appropriate water and be heated to the 10-15 minute that seethes with excitement again, 2-3 time repeatedly, measure the pH value of sour water, pH value is made to be 6-7, if when the pH value of 2-3 rear sour water is less than 6-7 repeatedly, adds industrial Na (OH) in treatment trough, then survey pH value;
(5) wax liquid qualified after, through being furnished with being pumped in stationary tub of screen pack.
Preferably, hydrochloric acid is added in wax material in described step (three).
Preferably, in described step (five), qualified wax liquid just can enter next process in static more than 2 hours in stationary tub.
In this description, the present invention is described with reference to its specific embodiment.But, still can make various amendment and conversion obviously and not deviate from the spirit and scope of the present invention.Therefore, description is regarded in an illustrative, rather than a restrictive.
