Embodiment 1

[0045] A method for preparing crack repairing mud for semi-finished products of sanitary ceramics, comprising the steps of:

[0046] (1) Prepare basic mud, that is, weigh each component according to the following weight percentage:

[0047]

[0048] Fully mix the above components with water and ball mill to obtain the basic mud. The concentration of the basic mud is 350-360g / 200mL, and the particle size is <10um: 56-60%;

[0049] (2) Weigh 85-95 parts by weight of the above basic mud and 5-15 parts by weight of high-temperature refractory cotton, fully stir and mix evenly, and then dehydrate to obtain the semi-finished sanitary ceramic crack repair mud; the above-mentioned high-temperature refractory cotton is standard silicon Acid aluminum fiber cotton (1260°C), the fiber length of which is pre-treated to be 2-4mm;

[0050] Above-mentioned back compact powder comprises the component of following percentage by weight:

[0051]

[0052] The above-mentioned regenerated p...

Embodiment 2

[0060] (1) Use a blade to scrape the part that needs to be repaired on the semi-finished sanitary ceramics until there is no crack, and wet the part with water;

[0061] (2) Use the crack repairing mud to make mud strips to repair the above-mentioned treated parts that need to be repaired, and compact them to avoid internal air bubbles;

[0062] (3) After the repair is completed, dry the repaired part and polish it until there is no obvious concave-convex feeling compared with other parts;

[0063] (4) Glaze the part to be repaired after drying to avoid poor glazing in the later glazing process;

[0064] (5) After brushing the glaze, it can be glazed according to the normal product and fired at 1190℃~1210℃.

[0065] In addition, according to different crack lengths, brushing repair and mud strip repair can be selected for repair. The specific implementation is as follows:

[0066]

[0067] Note: When scraping the cracked part, it must be scraped to the place where there i...

Abstract

The invention discloses sanitary ceramic semi-finished product crack-repairing slurry and a preparation method thereof. The crack-repairing slurry comprises the following components in parts by weight: 85-95 parts of base slurry and 5-15 parts of high-temperature fireproof cotton, wherein the base slurry comprises the following components in percents by weight: 40-59% of return blank powder, 20-30% of quartz powder, 20-30% of potash feldspar powder, 0.1-0.8% of gray pigment and 0.05-0.15% of a polymer binder. The sanitary ceramic semi-finished product crack-repairing slurry is capable of repairing long cracks and large bump defects, and the repairing qualified rate is 80% or more. The crack-repairing slurry is capable of further improving company production power and product qualified rate, and reducing unnecessary waste.

Description

technical field [0001] The invention belongs to the field of inorganic non-metallic materials, and in particular relates to a semi-finished sanitary ceramic crack repairing mud and a preparation method thereof. Background technique [0002] The production of sanitary ceramics is high-temperature and slow-fired, which requires high quality of semi-finished products. Even if there are small cracks, large defects will appear during the firing process. The traditional semi-finished product repair process only repairs defects such as tiny cracks or small bumps, and cannot effectively repair defects such as longer cracks and larger bumps. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art and provide a crack repairing mud for semi-finished sanitary ceramics. [0004] Another object of the present invention is to provide a method for preparing crack-repairing mud for semi-finished sanitary ceramics. [0005] Anoth...
