Abstract
A kind of Graphite pad production technology, the invention discloses Graphite pad production technology, comprises the following steps：1) preheated mold, mould is heated 100 180 DEG C；2) powdered graphite, accelerator and binder are pressed 2:1:1 weight proportion uniformly mixes stand-by；3) mixture is put into mould, is then put into heating furnace together with mould, charging temperature is controlled below 250 DEG C, is warming up to 350 degrees Celsius, and kept for 13 hours；4) cylindric blank is immersed in vulcanization pond and saponification pond successively, the zinc calcium that concentration is 8 9% is filled in phosphating pond and vulcanizes liquid, the temperature of zinc calcium vulcanization liquid is 45 50 DEG C, and dip time is 25 30 minutes；5) rinsed using running water, then dried up using air inducing equipment；6) take out, be cooled to room temperature；7) deburring, burr is taken out, processing cutting, finished product is made.The present invention is simple to operate, and technique is ingenious, not easy to wear through gasket seal produced by the invention, durable in use.
Description
Technical field
The present invention relates to sealing material field, specifically, is related specifically to a kind of Graphite pad production technology.
Background technology
Encapsulant, which draws, just refers to that can bear seam displacement is embedded in the material in building joint to reach airtight, watertight purpose
Material is referred to as encapsulant.Sealing member material has metal material (aluminium, lead, indium, stainless steel etc.), also there is nonmetallic materials (rubber, modeling
Material, ceramics, graphite etc.), composite (such as rubber-asbestos board, aerogel blanket-polyurethane), but most commonly used is rubber-like
Elastomeric material.Existing gasket seal is not wear-resistant, and service life is shorter.
The content of the invention
The technical solution adopted for the present invention to solve the technical problems is：A kind of Graphite pad production technology, it is characterized in that,
Comprise the following steps：
1) preheated mold, mould is heated 100-180 DEG C；
2) powdered graphite, accelerator and binder are pressed 2:1:1 weight proportion uniformly mixes stand-by；
3) mixture is put into mould, is then put into heating furnace together with mould, charging temperature is controlled below 250 DEG C, is risen
Temperature is kept for 1-3 hours to 350 degrees Celsius；
4) cylindric blank is immersed in vulcanization pond and saponification pond successively, the zinc calcium that concentration is 8-9% is filled in phosphating pond
Vulcanize liquid, the temperature of zinc calcium vulcanization liquid is 45-50 DEG C, and dip time is 25-30 minutes；
5) rinsed using running water, then dried up using air inducing equipment；
6) take out, be cooled to room temperature；
7) deburring, burr is taken out, processing cutting, finished product is made.
The beneficial effects of the invention are as follows：The present invention is simple to operate, and technique is ingenious, is not easy through gasket seal produced by the invention
Abrasion, it is durable in use.
Embodiment
Specific embodiment：A kind of Graphite pad production technology, it is characterized in that, comprise the following steps：
1) preheated mold, mould is heated 100-180 DEG C；
2) powdered graphite, accelerator and binder are pressed 2:1:1 weight proportion uniformly mixes stand-by；
3) mixture is put into mould, is then put into heating furnace together with mould, charging temperature is controlled below 250 DEG C, is risen
Temperature is kept for 1-3 hours to 350 degrees Celsius；
4) cylindric blank is immersed in vulcanization pond and saponification pond successively, the zinc calcium that concentration is 8-9% is filled in phosphating pond
Vulcanize liquid, the temperature of zinc calcium vulcanization liquid is 45-50 DEG C, and dip time is 25-30 minutes；
5) rinsed using running water, then dried up using air inducing equipment；
6) take out, be cooled to room temperature；
7) deburring, burr is taken out, processing cutting, finished product is made.
The beneficial effects of the invention are as follows：The present invention is simple to operate, and technique is ingenious, is not easy through gasket seal produced by the invention
Abrasion, it is durable in use.
Obviously, above-described embodiment is only intended to clearly illustrate example, and is not the restriction to embodiment.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of change or
Change.There is no necessity and possibility to exhaust all the enbodiments.And the obvious change thus extended out or
Among changing still in the protection domain of the invention.
