Abstract
The invention discloses a retouching composition for a ceramic part of a white glaze insulator. The retouching composition consists of the following raw materials: ceramic part body glaze of which the water content is 30% to 33% and a polyvinyl formal adhesive of which the viscosity is 8500 centipoises, wherein the volume ratio of the ceramic part body glaze to the polyvinyl formal adhesive is 2:(0.9-1.1). According to the retouching composition disclosed by the invention, the polyvinyl formal adhesive has an effect of increasing the binding force of the ceramic part body glaze and a ceramic part so that the ceramic part body glaze has a certain binding force with the ceramic part body during a sintering process, and the defects of glaze shrinkage and uneven glaze surface are unlikely to cause. After being retouched, the glaze surface has good binding ability with the original glaze surface and is unlikely to fall off. The retouched glaze surface is the same as the original glaze surface in color and luster; after being used for a certain time, the retouched glaze surface is observed to be in accordant with the original glaze surface in color and luster changes, peeling is hard to cause and the stability is good. A flaw position of the ceramic part is coated with the composition and then the ceramic part is returned to a kiln; the composition has no movement on the insulator, is free of glaze shrinkage and can be used for repairing flaw parts.
Description
Technical field
The invention belongs to the technical field of insulator surface process.
Background technology
Insulator is used to the isolator supporting wire, and insulator can ensure that wire and cross-arm, shaft tower have enough insulation.Insulator plays two basic roles in overhead transmission line, i.e. support wire and prevent electric current from returning ground.It is in operation and should be able to bears the loading of wire vertical direction and the pulling force of horizontal direction.It also undergos Exposure to Sunlight, drench with rain, the corrosion of climate change and chemical substance.Therefore, insulator should have good electric property, has enough physical strengths again.The safe operation of quality to circuit of insulator is very important.
The surface of insulator needs to be coated with glaze, and because the effect of insulator is insulated exactly, what be afraid of most is exactly make moist, and only in insulator surface coated in enamel, insulator could be sealed, and guarantees not make moist.In addition, on the basis ensureing interior insulator insulation strength, also to prevent insulator surface booty from piling up, making moist electric discharge, cause " " accident, by insulator surface coated in enamel for flashover, one is smooth, and dirt not easily retains, and two can be clean by wash dirt when being rainy.
Glaze on insulator is modal is white glaze, when in the process to insulator glazing, there will be the flaw that some are little, as depression, sand holes, breach, crackle etc.As adopted epoxy-like materials to carry out reclaim, after employing for some time, easily can there is situation that is different with former glaze paint color and luster and the face of repairing peeling, less stable.As adopted directly at flaw place coating porcelain piece body glaze, then put into kiln and return burning, there will be contracting glaze, the glaze namely filled is not positioned at flaw place, but has moved to elsewhere, can not repair flaw place.Therefore as there is flaw on existing insulator, the way of employing is directly scrapped, and can not become salable product come into operation through repairing, and like this, insulator is easy to scrap, and easily causes increasing of insulator production cost.
Summary of the invention
The invention provides a kind of white glaze insulator porcelain piece reclaim composition and reclaim method, occur contracting glaze to solve in the glaze paint of insulator pin flaw place reclaim, the problem of and peeling different with former glaze paint color and luster.
In order to solve the problems of the technologies described above, the invention provides following technical scheme: a kind of white glaze insulator porcelain piece reclaim composition, be made up of following raw material: the porcelain piece body glaze of water ratio 30-33%, the formaldehyde polyvinyl acetal that viscosity 8500 Chan moors sticks agent, and the volume ratio that described porcelain piece body glaze and formaldehyde polyvinyl acetal stick agent is 2:0.9-1.1.
Porcelain piece body glaze chemical composition is as follows in mass ratio: silicon-dioxide is 66.2-67.2 part, aluminium sesquioxide is 15-16 part, ferric oxide is 0.1-0.4 part, calcium oxide is 3.5-3.9 part, magnesium oxide is 3.8-4.2 part, potassium oxide is 4.2-4.6 part.
Adopt the reclaim method of above-mentioned reclaim composition, comprise the following steps:
A, porcelain piece fault location is polished insulator body color;
B, with alcohol washes polishing after wound;
C, spread upon wound after polishing with little writing brush by smooth for reclaim glaze, and to dry by heat lamp;
D, mend to be polished flat;
E, enter kiln and return burning.
Principle of the present invention is that formaldehyde polyvinyl acetal sticks the bonding force that agent adds porcelain piece body glaze and porcelain piece, makes porcelain piece body glaze have certain sticking power with porcelain piece body in sintering process, not easily causes the unequal defect of contracting glaze, glaze paint.
Compared with prior art, the invention has the advantages that: the glaze paint 1, after reclaim and former glaze paint excellent bonding performance, difficult drop-off.2, the glaze paint after glaze is consistent with former glaze paint color and luster, observes after using the regular hour to it, and the glaze paint after glaze changes consistent with former glaze paint color and luster, and not easily peeling, stability is better.3, return kiln after this composition being coated to flaw place, this composition can not be moved on the insulator, there will not be contracting glaze, can repair for flaw place.
Further, the volume ratio that described porcelain piece body glaze and formaldehyde polyvinyl acetal stick agent is 2:1, adopts the insulator of this volume ratio, and physicals is best.
Further, in step c, the time of baking by heat lamp is that 30 minutes glaze paint after heat lamp is baked can not flow.
Further, in step c, cutter and sand paper is adopted to polish.Position because of flaw is unfixing and region is less, therefore adopts the artificial simple tool that uses to polish.
Further, in step e, burning till top temperature is 1245 degrees Celsius, and firing time 26 hours is identical with the condition of insulator gloss firing first, does not need to regulate firing temperature separately, conveniently can put into kiln together with other insulators and fire.
Embodiment
The formula that employing white glaze insulator porcelain piece reclaim composition carries out reclaim is as shown in the table:
Table one
Need that porcelain piece body glaze and formaldehyde polyvinyl acetal are sticked agent before adopting above-mentioned formula to carry out reclaim to mix, then carry out reclaim to insulator, the experimental data of the Insulators Used after reclaim is in table two:
Table two
Can find out from table two kind, the insulator after reclaim meets the regulation of country to insulator standard.
Adopt above-mentioned formula to carry out reclaim to insulator, the chemical composition at reclaim place is in table three:
Table three
Embodiment 4
The present embodiment is the method to there being the white glaze insulator porcelain piece of flaw to carry out reclaim, there to be the insulator of crackle:
Specifically comprise the following steps:
A, by porcelain piece cracks (macroscopic crackle) polish, make it expose the color of insulator body;
B, with alcohol washes polishing after wound;
C, spread upon wound after polishing with little writing brush by smooth for reclaim glaze, and by heat lamp roasting 30 minutes;
Mend polishes flat by d, employing cutter and sand paper;
E, enter kiln and return burning, burning till top temperature is 1245 degrees Celsius, firing time 26 hours.
Finally, taken out by insulator in kiln, the overall appearance glaze paint of insulator is smooth, glossy, and glaze colours is evenly in white, and reclaim place outward appearance glaze paint is smooth, and glaze colours is even, consistent with overall porcelain piece glaze colours.
For a person skilled in the art, under the prerequisite not departing from structure of the present invention, can also make some distortion and improvement, these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.
