Q: What are the advantages and disadvantages of vitrified polished tiles?
A: Compared with stone, vitrified polished tiles have several advantages:
1. High hardness, the index reaches 8 degrees Mohs;
2, the gloss can reach more than 80 degrees on the mirror;
3, no maintenance; vitrified polished tiles are easier to maintain than stone, no stone maintenance trouble.
4, the natural stone color difference is more serious, the vitrified polished brick will not have the color difference of natural stone, and can achieve the same color.
5, stone is easy to produce radiation, the radiation of well-known brand vitrified brick is very small.
Q: Is the living room floor paving tile good for glazed tiles or vitrified tiles?
A: The working environment in the living room is less affected by temperature and pollution. It is relatively good environment. Therefore, the material requirements of the tile itself are not very high. The only thing to note is that according to the light and personal preference of the living room. Select the specific color; if you want to choose the tile for the living room, because there are more people entering and leaving, it is best to choose some well-known brands of products, the surface hardness is higher, and will be more secure, not easy to scratch. From the current social trends, the choice of bricks in the living room, or more floor tiles. Glazed tiles are used more in bathrooms and kitchens.
Q: Does the vitrified brick need to be soaked in water before laying, and if so, how long does it take to soak?
A: Dry shop wet shop will do, wet shop soaked into the tile does not take bubbles as the standard!!
Q: I want to know what model is used for tiled cement now?
A: The indoor part of the general home improvement is best to use cement below 425. If the cement number is too high, the effect is not ideal. Especially the quality of some small factories is not too high. The sulfur content is too high and the strength is slightly poor. A little turning of the glazed surface will cause some defects on the surface of the brick, so it is better to use a low-grade cement. When attaching the exterior wall tiles, it is best to select some cement with a higher mark, and add some glue to increase the anti-shedding ingredients. :
Q: Should the bathroom floor tiles be dry or wet?
A: It should be wet.
Q: Which kind of tile is better in temperature resistance? Which kind of tile wear resistance is better? Please introduce it to the experts.
A: If the tile itself is made into a classification, the glazed bright tile has better stain resistance. From the perspective of wear resistance, the wear resistance of the vitrified tile is better.
Q: After the tile is laid, what is the acceptance criteria?
A: Main points of acceptance method:
1. Measure with horizontal paper, and see if the brick joints are aligned or not.
2. Step on it to see if there is any local noise. The reason for this may be that when cement is used for bonding, the cement is not evenly applied, causing a place to step on and feel empty.
3, is to see the hook and even uneven. Pay attention when laying the paving, and dry the cement in time when jointing.
In addition, the acceptance of the paving is related to the quality of the ceramic tile. The cement internal coagulation process was not completely completed when it was just laid. It is best to wait until after 20 days for the strength of the cement to come up completely, and then see if the tile will crack.

Detail introduction for above main accessories
1.Motor and controller:
The garage door operator is designed for residential overhead sectional and tilt doors.
The operator memorizes the limit positions and unique braking system that slows the unit down at the end of its travel.
Rolling code remote control with max. 20 pcs hand transmitters.
The operator is equipped with a manual release lever which allows manual operation of the door in case of power failure.
The controller has a security LOCK function which prevents operation of the door from transmitter.
2.spring break device:
Sectional doors are hinged and they bend in the tracks as the door opens and closes. Many of these doors are counterbalanced with extension springs, also designated "stretch springs," and they have seven characteristics. The length is the measurement of all the coils pressed together. This, along with the inside diameter of the coils and wire size - the thickness of the wire from which the springs are made - determine the stretch, the distance the spring is extended - normally half the door height, and pull, the force the spring pulls when stretched its normal length. The type of ends determine how the ends of the spring are mounted. The initial tension is the percentage of pull needed to separate the coils. This is determined by the pitch with which the springs are wound. On sectional garage door springs this is normally 15 percent. For example a 100 pound pull spring requires 15 pounds of weight to separate the coils; when a door is open the two springs will support 15 pounds of door weight without any stretch.
Most extension springs are made of oil tempered wire. These are normally coated or painted. Some springs are made of galvanized wire.
