Abstract
The invention discloses a production technology for a graphite gasket. The production technology comprises the following steps: (1) graphite powder, an accelerant and a plasticizer are uniformly mixed for use at the weight ratio of 3:1:1; (2) a die is preheated and the die is heated at the temperature of 180 DEG C-220 DEG C; (3) the mixture is put in the die, the mixture and the die are together put in a heating furnace with the temperature controlled below 300 DEG C at the beginning, and the temperature is increased to 500 DEG C and kept for 2-3 h; (4) the die is taken out and cooled to the indoor temperature; (5) a cylindrical blank is immersed into a vulcanized tank and a saponified tank in sequence, the vulcanized tank is filled with a zinc-calcium vulcanized liquid with the concentration of 6-9%, the temperature of the zinc-calcium vulcanized liquid is 45-65 DEG C, and the immersing time lasts for 25-30 min; (6) tap water is used for rinsing, and air inducing equipment is used for drying; (7) trimming, burr taking out, processing and cutting are conducted to obtain finished products. According to the invention, the production technology is simple in operation and skillful in technology, and sealing gaskets produced by the production technology have low probability of wearing and are durable.
Description
Technical field
The present invention relates to sealing material field, specifically, specially refer to a kind of Graphite pad production technology.
Background technique
Sealing material just draws and refers to that can bear seam displacement is called sealing material with the material that reaches airtight, watertight object and embed in building joint.Sealing member material has metallic material (aluminium, lead, indium, stainless steel etc.), also having nonmetallic material (rubber, plastics, pottery, graphite etc.), composite material (as rubber-asbestos slate, aerogel blanket-polyurethane), is rubber-like elastomeric material but use maximum.Existing gasket seal is not wear-resistant, and working life is shorter.
Summary of the invention
The object of the invention is to for deficiency of the prior art, provide a kind of Graphite pad production technology, to address the above problem.
Technical problem solved by the invention can realize by the following technical solutions:
Graphite pad production technology, comprises the steps:
1) weight proportion of powdered graphite, promoter and binder being pressed to 3:1:1 evenly mixes stand-by;
2) preheated mold, by mold heated 180-220 DEG C;
3) mixture is put into mould, then put into oven together with mould, charging temperature is controlled at below 300 DEG C, is warming up to 500 degrees Celsius, and keeps 2-3 hour;
4) take out, be cooled to room temperature;
4) cylindric blank is immersed successively in sulfuration pond and saponification pond, in phosphating pond, filling concentration is the zinc calcium sulfuration liquid of 6-9%, and the temperature of zinc calcium sulfuration liquid is 45-65 DEG C, and dip time is 25-30 minute;
5) use tap water to carry out rinsing, then use air inducing equipment to dry up;
6) deburring, takes out burr, and processing cutting, makes finished product.
Preferably, described step 2) in the optimum temperature of preheating be 200 DEG C.
