Abstract
The invention discloses a method for uniformly dispersing the doped rubber of a hard alloy mixture, relates to the technical field of manufacturing for hard alloy, and aims at solving the technical problems of bad dispersion uniformity of the doped rubber, easiness to generate rubber particle holes having diameters of equal to or greater than 125 microns on hard alloy products, and the like in the present rubber process. The method for uniformly dispersing the doped rubber of a hard alloy mixture disclosed by the invention comprises the following steps of: a) calculating the bulk volume of the mixture undoped with rubber according to a formula: the bulk volume of the mixture undoped with rubber = the weight of the mixture undoped with rubber/the bulk density of the mixture undoped with rubber; b) adding solvent oil in the mixture undoped with rubber put in a rubber-doping machine according to a ratio that 70-75 ml of the solvent oil is added every 1000 cm<3> bulk volume of the mixture undoped with rubber; c) stirring and mixing the mixture undoped with rubber after being added with the solvent oil; and d) adding rubber solution in the mixture undoped with rubber after finishing stirring and mixing, so as to perform a rubber-doping treatment.
Description
Technical field
The present invention relates to Wimet manufacturing technology field, particularly a kind of rubber process carbide alloy mixture is mixed the finely dispersed method of glue.
Background technology
The Wimet manufacturing process mainly is comprised of compound preparation, moulding and sintering three parts.In order to guarantee the compound powder pressing forming, all to add a certain amount of shaping binding agent in the compound powder.The kind of shaping binding agent mainly contains two kinds of paraffin and bunas.Two kinds of processing method differences that the shaping binding agent adds, paraffin technology is paraffin to be put into ball mill barreling together with the compound powder mix, rubber process is a certain amount of compound powder to be put into screw-blade stir the companion and mix the glue machine, then rubber solutions is incorporated in the compound powder that stirs the companion mixes.The dispersing uniformity missionary society of strike-through affects the quality control of the sub-hole of hard metal article micelle, causes hole to exceed standard.Existingly mix the dispersing uniformity that gluing method is difficult to guarantee fully strike-through, often there is the sub-hole of the micelle that is equal to and greater than 125 microns to occur, the sub-hole of the micelle that is equal to and greater than 125 microns in hard metal article can be arrived better control, the dispersing uniformity of rubber process strike-through must effectively be solved.
Summary of the invention
The present invention is intended to solve that the dispersing uniformity of existing rubber process strike-through is relatively poor, hard metal article easily produces and is equal to and greater than 125 microns technical problems such as the sub-hole of micelle, with provide a kind of have can effectively control hard metal article and be equal to and greater than a kind of carbide alloy mixture that 125 microns sub-holes of micelle occur and mix the finely dispersed method of glue.
The objective of the invention is to be achieved through the following technical solutions.
A kind of carbide alloy mixture is mixed the finely dispersed method of glue, comprises the steps:
A) according to formula: do not mix the bulk volume of glue compound=do not mix glue compound weight/do not mix the loose density of glue compound, calculate the bulk volume of not mixing the glue compound;
B) add the ratio of solvent oil 70-75ml in the every 1000cm3 of the bulk volume of not mixing the glue compound, add solvent oil being placed in the glue compound of not mixing of mixing in the glue machine;
C) add the glue compound of not mixing after solvent oil to mix with above-mentioned;
D) add rubber solutions to advance to mix glue to process completing the glue compound of not mixing that mixes.
A kind of carbide alloy mixture of the present invention is mixed the finely dispersed method of glue, wherein said step b) in solvent oil be No. 120 solvent oils, adding speed is per second 40-50ml.
A kind of carbide alloy mixture of the present invention is mixed the finely dispersed method of glue, wherein said step c) in to mix the time be 20-30 second.
A kind of carbide alloy mixture of the present invention is mixed the beneficial effect of the finely dispersed method of glue:
1. mix the sub-hole of gluing method comparison hard metal article micelle with tradition and can arrive better effectively control, can eliminate the sub-hole of the micelle that is equal to and greater than 125 microns;
2. method is simple and reliable.
Embodiment
Rubber solutions has very strong cohesiveness, in case contact with the compound powder, screw-blade stirs the companion and mixes the glue machine and stir the companion and mix to be difficult to again its uniform dispersion, adding solvent oil that compound is infiltrated before tradition is mixed gluing method processes, make the surface of compound form one deck oil film, because the existence of oil film has increased wettability and oilness between rubber solutions and compound, promoted rubber solutions spreading out voluntarily and disperseing in compound, reduce and reduced the glue aggregation of particles, having improved the dispersing uniformity of mixing glue.If but directly solvent oil is added in rubber solutions, can only dilute rubber solutions, it not only can not improve wettability and oilness and promotion rubber solutions spreading out voluntarily and disperseing in compound between rubber solutions and compound, also can increase the control difficulty of follow-up oven dry, increase the glue aggregation of particles, cause the generation of the sub-hole of micelle.
Below the invention will be further described by specific embodiment.
Embodiment 1:
The YG6 carbide alloy mixture
Every a collection of to mix glue compound weight be 30 kilograms, and the loose density of not mixing the glue compound is 3.2 grams/cm3, and calculating this batch, not mix the bulk volume of glue compound be 9370cm3.
Add the ratio of solvent oil 70.4ml to calculate in the every 1000cm3 of the bulk volume of not mixing the glue compound and need to add solvent oil 660ml No. 120, add solvent oil 12 seconds, stir companion mixing time after 20 seconds more routinely technique add rubber solutions to advance to mix glue.
Calculate according to every batch of weight and loose density of not mixing the glue compound bulk volume of not mixing the glue compound, calculate the solvent oil add-on according to the bulk volume of not mixing the glue compound again and add solvent oil, compound is mixed glue and is uniformly dispersed, and the hard metal article that makes occurs without being equal to and greater than 125 microns sub-holes of micelle.
Embodiment 2:
The YG6X carbide alloy mixture
Every a collection of to mix glue compound weight be 25 kilograms, and the loose density of not mixing the glue compound is 2.7 grams/cm3, and calculating this batch, not mix the bulk volume of glue compound be 9260cm3.
Add the ratio of solvent oil 70.2ml to calculate in the every 1000cm3 of the bulk volume of not mixing the glue compound and need to add solvent oil 650ml, add solvent oil 15 seconds, stir companion mixing time after 20 seconds more routinely technique add rubber solutions to advance to mix glue.
