Recently, disputes have arisen in the terminal market due to issues with ceramic tile quality and after-sales service. The source of the problem this time was the high breakage rate of tile cutting.
More than 10 tiles were cut out of 50 pieces
The manufacturer believes it is a probability issue
On October 19 this year, Ms. Zhong from Xinyu City spent more than 12,000 yuan to order a ceramic tile from a local ceramic tile brand store. After the tiles arrived, the decorator started laying them. However, when he had to cut the corners after laying most of the area, he found after cutting three or four pieces that the tiles were cracked one by one, and he refused to continue pasting them no matter what. After Ms. Zhong contacted the store, the store arranged for professionals to cut the tiles at home. Three pieces were cut and two were scrapped. After the clerk saw this situation, he immediately contacted the hauling department and hauled away 9 tiles, promising to send them back after processing, but nothing was done about it. Ms. Zhong said that at first the store promised to compensate 25,000 yuan, but the next day it regretted not to compensate.
The reporter contacted the store and the manufacturer respectively, and the person in charge said that there were no quality problems with their ceramic tiles. "There are no problems with the products when they leave the factory, but the secondary processing involves many factors. It may be that the masonry skills are not good or the blades are not good." There are many factors." The manufacturer said that there is no cutting indicator in the quality inspection of ceramic tiles. Ceramic tile cutting is a probabilistic problem. It does not break every piece, but the damage rate is a little higher.
After hearing the responses from the store and manufacturer, Ms. Zhong found it unbelievable. In terms of probability, her family bought more than 50 pieces of this brand of tiles, and more than 10 of them were damaged. This probability is not low. . Ms. Zhong could not accept the store's explanation, so she reported the matter to the market supervision department in her jurisdiction and requested an investigation.
Affected by various factors, some damage to ceramic tile cutting is inevitable, but the damage rate has exceeded 20% (and may be higher). It is no wonder that consumers find it unacceptable. The high breakage rate of the ceramic tiles purchased is a problem encountered by many consumers. Not only Ms. Zhong, but also the ceramic tiles purchased by Mr. Hu from Hunan also had similar problems.
9 pieces were cut in a row at the same position
Store: Processing in the factory will prevent cracking
In April this year, some media reported that Mr. Hu asked a Taoist in HunanPorcelain brand purchased a batch of ceramic tiles. However, when the decoration master performed special-shaped cutting operations such as drilling holes on 600×1200 (mm) products, a large crack immediately appeared in the tiles as soon as the cutting machine was moved, making it impossible to use. Mr. Hu said that when he first cut two tiles, he thought it was a problem with the decorator, but later, 9 tiles were cut in succession at the same position. He believes that no matter what kind of tiles, if the quality is up to standard, such a thing is unlikely to happen. He also said, "This tile brand has also been cooperating with our master craftsmen for many years, and there have been no problems with the tiles I bought before."
However, the store's attitude towards this matter made him angry: the store initially admitted that there was a quality problem, but refused to admit it when it came to compensation, thinking that there was something wrong with the cutting master (craft). Regarding the quality of the product, the store said, "The factory said there is no problem. (This batch of products) will not crack if it is processed in the (manufacturer's own) processing plant." He also offered to help Mr. Hu get the product to the manufacturer. The processing factory will process it and send it back.
But Mr. Hu disagrees. On the one hand, he believes that normal quality ceramic tiles cannot be cut normally only with the manufacturer's cutting machine. Moreover, the store did not inform in advance that "the product needs to be processed by the manufacturer's processing plant"; On the other hand, the size and size of ceramic tile processing, cutting, and polishing need to fit the different locations of the house, and it is difficult for products processed in processing plants to meet this requirement. After final negotiation, the store took back the 20 used tiles and compensated Mr. Hu 1,000 yuan.
The reasons for damaged ceramic tiles are complex
How to reduce it?
In fact, in addition to ceramic tiles, the cutting breakage rate of rock slabs, which has emerged in the ceramic industry in recent years, is much higher than that of ceramic tiles due to higher production technology requirements. Some senior experts in the industry believe that many products produced by ceramic factories will crack when they are cut for engineering applications. The cracking ratio is between 5% and 30%. Products such as large slabs and rock slabs are more likely to stand out due to their large area. question. Experts said that the cracking problem of rock slabs is related to "the composition of the green body, the combination of the green body and the glaze, the expansion coefficient, the firing speed, the stress number of the brick after cooling and the final cutting method."
From this point of view, ceramic tile cutting damage is actually an industry-wide problem. How to reduce tile cutting breakage? On the one hand, ceramic manufacturers must have strict quality control requirements on product quality at the production end. At the same time, they must also provide good after-sales service. Even if the package is not damaged, they must have a correct attitude in solving problems, so that brands and stores can develop healthily. On the other hand, it is crucial to improve the cutting and processing technology of ceramic tiles.
If you want to cut ceramic tiles with less damage, correct operation methods are very important. Understanding some common cutting issues and precautions can also help us reduce the occurrence of tile breakage.
Notes on four common cutting methods:
(1) Tile parquet and arc cutting
Ceramic tile parquet is generally processed by a computer-controlled hydraulic cutting machine. For small quantities, you can directly purchase the pre-assembled patterns. For large quantities, you can entrust a professional processing factory to process them.
(2) L-shaped, corner cutting
The tiles need to be cut immediately at the corners of the paving. Generally, a portable tile cutting machine is used to saw from the front of the tiles. If the amount of renovation work is large, you can use a desktop cutting machine with better cutting results.
(3) Square hole with larger area
If you need to open a square hole for an electrical switch on the tile wall, you can use a marble machine with a professional blade (corrugated sheet and brazing sheet) to mark and position the back of the tile, and then cut from the back. Water needs to be added to assist cooling during cutting.
(4) Small round hole
For the small holes used to install screw holes such as towel racks and coat hooks, they should be operated after the paving is completed and dried. Use a hand electric drill with a glass drill bit to drill through the tiles, and then use an impact drill to drill the cement. or wall.
Analysis of common problems in tile cutting:
Generally speaking, there are three types of damage to tiles when processed by ordinary tile cutting machines: (1) The edges of the tiles are not straight; (2) The edges of the tiles collapse; (3) There are many burrs on the edges of the tiles.
When the edge of the tile is not straight when cutting, check whether there is dirt accumulation on the table of the cutting machine;
When encountering ceramic tile chipping, the main reason may be that the operator cuts too fast when processing; it may also be that the cutting blade becomes frustrated after being used for a long time, and the cutting blade needs to be replaced;
If the ceramic tile is chipped or cornered, pay attention to whether the blade is bent or deformed during cutting. If bending or deformation occurs, you need to replace the blade with a new one or change the direction of the blade;
The chipping of edges and corners of ceramic tiles may also be caused by the movement of the tile cutting machine, and the tile cutting machine should be debugged.
If only one or two tiles need to be cut, you can also cut them yourself with a glass knife. First use a metal knife to mark the cutting line, then flip the tile so that its back is facing up, and place the cutting lineOn a hard plane corner, use both hands to break off the tiles at both ends of the dividing line, and the tiles can be disconnected. When breaking the tiles, the force on the tiles must be even, otherwise the edges and corners may be damaged.
