Beautiful wallpaper, environmental protection, non-toxic, many families are willing to choose wallpaper as the main material of the decoration, but many problems such as the moldy edges of the wallpaper make many people discourage. In fact, these problems can be avoided, the quality of wallpaper and accessories is the key, the other is the wall before the construction of the wall to deal with the problem, the following Xiaobian to everyone to share the next wallpaper wall treatment methods and requirements. Hope to help you!
Common wall problems and corresponding solutions
Powder wall: that is, there is a loose powder on the wall (can be easily removed by hand), should be sanded to remove, leveling and then brush the wallpaper base film, wait until dry after you can paste wallpaper.
Light wall: The wall surface is very smooth, it is not easy to absorb glue, it is not easy to dry, and then the force will drop. Sanding is needed to paste the wallpaper.
Filling putty: Add more white glue in the putty to make it firm and not crack.
Flat putty: Put a small amount of white glue in putty for sanding. Important tips Gypsum powder plus white glue instead of batch putty can speed up drying and shorten construction time.
The main process of plasterboard surface wallpaper:
Cleaning, filling gaps, grinding sandpaper ---- seams at the seams --- find putty, sandpaper polishing ---- brush bottom glue again --- wall marking line ---- wallpaper brush adhesive - --- Base brush adhesive ---- wallpaper paste ---- patchwork, lap joint, pair of flowers - press adhesive and air bubbles - wipe the glue out of the ---- clean up trimming
Damp wall treatment:
The wall of the room is damp and even moldy. At this time, anti-seepage liquid can be applied on the wall surface to form a colorless and transparent waterproof film layer on the wall surface, which can prevent the infiltration of foreign moisture, keep the wall dry, and then can decorate the wall surface. If the wall is damp, let the damp wall dry for a period of one to two months. Brush a layer of water-proof slurry mixed with cement on the wall to prevent moisture. Secondly, the wall pits are filled with gypsum putty. After drying, the wall surface is smoothed with sandpaper. Then, the primer can be coated with rollers on a dry clean wall twice, or sprayed.
The wall surface treatment is to make the wall surface smooth, clean, dry and free of cracks, voids, solid and dust-free.
Cement, Brick Wall: The wall surface is flat, flattened with putty, brushed with a thin varnish and allowed to dry.
Gypsum board, plywood, and board; joints exist, so the joints must be first patched and then ashed. The function of the varnish and the sealer is to cure and protect the surface of the putty. It can also enhance the waterproof, anti-mold and anti-alkali functions of the wallpaper. The paint should be applied after the putty is completely dry. The wall treatment of the wallpaper-pasted wall is basically the same as the wall treatment of the brush coating. Therefore, the brush coating wall is suitable for changing the wallpaper to prevent light transmission and must be polished.
Summary: The above method and requirements for wallpaper wall treatment , Xiao Bian to roughly introduce here! Did your family meet the requirements? More home improvement knowledge, please pay attention to this site information!

High Speed Door Motor And Control Box
Our company have German SEW Motor, Japan Mitsubishi Controller. Our own brand Hofic servo motor and controller. Chinese famous brand SEJ motor and Holip controller.
About our German SEW Motor and Japan Mitsubishi Controller: It is easy to find the ideal energy-efficient motor for your application at SEW. The series has a suitable design in its range for the globally applicable efficiency classes. Select the power and frequency within this motor design and you have already taken care of the most important selection criteria.All other motor options are of course available independently of the efficiency class. A comprehensive braking concept and cost-optimised built-in encoders ultimately complement the motor range. Comprehensive braking concept and combinations i.e. up to three different brake sizes per motor size featured in the range: Cost-optimised built-in encoders integrated into the motor. Motors for efficiency classes IE1 to IE4.Compact design saves space and costs. Future-proof, also as regards environmental protection (standards). Reduction in operating costs when using energy-efficient motors; our energy-efficient motors conform to the efficiency classes.
About servo High Speed Door Servo Control System: Our rolling gate servo control system is suitable for high speed and high usage soft and hard rolling gate. The whole system is in a small and light package, it has high torque and high operating speed, lower noise, high reliability, smooth and soft operating curves, it`s suitable for high speed and usage environment. The rolling curtain can be controlled by pull switch, push button, Bluetooth, ground radar, ground magnetic sensors. Operating Speed: 1M/s; Operating Width: ＜16 ㎡; Daily operating time: ＞2000 time; Rated voltage: 220v; Rated Output: 0.75 KW/1.5KW.
The system can operated via: 1) control box; 2) inching electronic control; 3) continuous automatic operation; 4) emergency stop; 5) single side operation box; 6) time delay; 7) ground radar and/or magnetic sensors. Please refer to Wiring Terminal for eternal connections.
System has fuse/safety wire shutdown switch for three-phase power protection, fuse/safety wire for operating circuit protection, and temperature sensing relay for motor protection.
Stroke Controller utilizes absolute value encoder. Connect the absolute value encoder and reducer via encoder`s axle, and fix the wings on to the reducer, than insert the aviation plug into plug receptacle.
The mounting screw for the control box must inspect regularly to prevent screw been getting loose and falling off. Check the internal and external wirings. Check and change the oil for the redactor on regular basis.
Precision: The system use Full closed-loop servo control and Double Encoder design. This is to ensure long operating life and to prevent overshooting during operating.
Stability: The system utilizes integrated design concept, in order to simplify internal wiring and prevent any function caused by wiring and terminal connections.
High Speed: Motor max speed is 2500 rpm; door max operating speed is 2 m/s.
Smooth: The torque servo system can adjust torque to the load automatically, and its speed curve mode step less speed regulating to ensure a smooth operation.
About SEJ motor and Holip controller: Three-phase asynchronous motor with magnetic brake has broad uses, It is suitable for various mechanical main drive and auxiliary drive, and it is also used for various required rapid stopping and correct positioning. The braking time within 0.2 second. Electric motor is added the DZM series direct current electromagnetic arrester by the basic series(Y series) electric motor.The protection class of electric motor part is IP44,the arrester part is IP23.if be applicable to bad environment can also make the arrester part into IP44,but customer have to put forward a special request while ordering,the manufactory can design a manufacturing exclusively. Its structure diagram is picture 1 and 2,picture 1 is the structure with hand release.Picture 2 is the structure without the hand release.Its operating principle BE, after being to make the retardation coil(6)to connect direct current power supply,because of the function of electromagnetic force,electromagnet(7)attract gag bit(5),and compress spring(24),make arrester disc(2)away from the friction surface of the gag bit(5)and shield(26)(the electrical motor can immediately operate normally).When the power supply cuts off after,the electromagnet(7)loses electromagnet force,the spring(24)releases the gag bit(5)and compress tightly to arrester disc(2),the arrester function,stop(the motor shaft)quickly,make electric motor shop turning to move,for the second time connect power supply will repeat above-mentioned action.
