Xin xiang Ceramic Mug Manufacturer, Ceramic coffee mug in the production process, the blank in the production process has a production process - repair blank.
For the bonded blank, because its surface is not very smooth, the edge of the mouth has a burr, some still have mold seams, and some products need further processing, such as digging the bottom, punching and so on, so it is necessary to further processing to fix the flat, known as the repair of the blank. Repair is a three-dimensional semi-finished product grinding process, so that it can adapt to the glaze operation and into the kiln firing of the fine billet. Repair is a necessary work in the injection molding and plastic molding industry. It has a great influence on the surface quality of the blank, and should be given enough attention. There are wet repair and dry repair. Wet repair is a lot of water in the body, still in the case of wet soft, suitable for more complex shape or need to be wet by the billet, this time the operation is easier and the knife is not easy to repair the billet is not easy to wear, the disadvantage is easy to move and operate in the process of the billet injury caused by deformation to improve the quality of the unfavorable. General bowls, pots, ceramic coffee mugs and other products that need to be processed, more wet repair, the moisture depends on the degree of processing to determine. Need plastic processing (such as perforation, etc.) and bonding of the blank, the wet repair moisture can be slightly higher, 16% - 19%, such as porcelain and fine ceramic blanks are generally 16% - 18%, while the coarse ceramic blanks are generally 8% - 16%. Wet repair methods, available scraper, foam molding scraping and polishing. Dry repair is in the body of the moisture content down to 6% - 10% or even lower moisture after drying (2%). At this time the billet strength increase, can reduce the deformation caused by moving injuries, to improve the quality of favorable, the disadvantage is that the dust is larger, but also on the repair of blank knife resistance is larger, easy to jump knife, repair the blank knife wear and tear is also larger, the operation of the technology is more difficult to master. Dry repair due to the low water content of the blank, available foam, rags, brooms, etc. dipped in water to repair the blank, can also be used to knife, sieve, etc. directly dry repair. Repair of blanks using many types of scrapers, different products, the shape of its use is also different. For example, sanitary porcelain repair scraper, according to its shape, can be divided into flat scraper, round scraper, crescent scraper three kinds. Flat scraper for the full semi-circular, generally adapted to repair the plane; round scraper is double arc, suitable for scraping the concave surface; crescent scraper for scraping the raised surface of the model counterpart seam traces, etc.. Scraper is generally double-sided blade, blade width in 5-10mm. scraping blanks according to the degree of convexity and concavity of the scraping blanks, change the scraper surface with the angle of the surface of the blanks for the operation.
When repairing blanks, we should not only emphasize the appearance quality, but also pay attention to the prevention of other quality defects. Therefore, special care should be taken during the operation. For example, when dry repairing the body of the blank, pay attention to the following points.
1. Dirty plaster, dirty flannel, dirty sponge and mud flakes on the surface of the blank must be removed to prevent defects in the appearance of the finished product.
2. Use mixed water to wipe the blank to paste the brown eyes on the surface of the blank, so as not to affect the quality of the finished product appearance.
3. The blank itself has air bubbles, generally around 5mm, can be plugged with dry billet crumbles, and then rolled with a hard object. If the bubble is more than 5mm to see if it can be plugged, if not plugged, can be used to scrape the scraper to scrape flat, so that there are no obvious traces, in order not to affect the appearance of good. If the bubble is large and has a certain depth, it is regarded as scrap.
4. The surface of the blank has obvious bump must be scraped flat.
5. If there is a small crack of 10mm long and 2mm deep in a certain part of the body, you can use a scraper to scrape it until there is no crack, and then scrape the surrounding parts flat.
6. body grouting eye with traces of the parts, be sure to use a scraper to scrape off, in order to prevent the emergence of the finished product of the mud strand defects. Blanks by dry repair, but also for polishing, inspection. Check when a look at the body of the blank wash surface, hidden holes; look at the eye holes, etc.; three look at the mold seam; four look at the sticky mouth part; five look at the sanding of dry blanks when the defective parts of the technical processing effect; six look at the accumulation of water. After the inspection, but also dry blanks to find the crack work.
