The high price and dry weather make it difficult for the rosewood to be popular in the market. Therefore, a new type of wood that perfectly replaces the rosewood has gradually entered the market and has caused great repercussions in the market. It is African rosewood. Since it is solid wood furniture, it will inevitably crack, then the African rosewood will be cracked after buying back a few years? Below, GO Jiaju is explained for you.
What is African rosewood?
African rosewood is also known as African black rosewood, Burke Sumu. Its heartwood is obvious, reddish purple or reddish brown, with deep purple stripes; sapwood white or light yellowish brown, slightly woody; wood dry density: 0.9~1.12 g / cm3, density is much larger than ordinary mahogany, weight Very heavy, sinking into the water. It takes a hundred years for the bulk material to become a material, with the resources available being reduced.
African rosewood advantage
1, beautiful appearance
The wood quality of African rosewood is definitely second to none in the market. Baidu Encyclopedia has a detailed introduction to it. Its appearance is beautiful, the heartboard surface and texture are quite beautiful, and the color is comparable to the red rosewood. It has a high dry density and a high quality, and can reach 0.9-1.12 g/cm3, even in the rosewood. Most of the wood is heavier, and it is not only resistant to corrosion and cockroaches, but also easy to process, and it has good light, sanding, paint and adhesive properties. It is perfect for any classical furniture.
2, good quality and low price
The most important thing about African rosewood is that its price is very affordable. The same table, the rosewood may be 70,000 or even more than 100,000, but the African rosewood currently only needs one or two thousand yuan, which is more than the price of rosewood. Five times lower, a set of three or four hundred thousand rosewood sofa sets, African rosewood can be easily taken for only a few tens of thousands of dollars, this price can be said to be the most important reason for its popularity.
3, material stability: traditional craft, once and for all.
African rosewoods are not easy to dry, but they are excellent in dryness. Once they are well dried during the manufacturing process, the cracking of the molded furniture is extremely low.
African rosewood cracks in two years
It can be seen from the above that the wood is stable and the degree of cracking of the furniture after molding is extremely low. Even in the northeast, it can almost guarantee that the whole side of the board will only crack two or three millimeters in two or three years, and the whole wood will not crack, and it will not affect at all. Use and aesthetics, a little repair can be a new look. Therefore, African rosewood furniture should pay attention to maintenance.
African rosewood maintenance method
African rosewood furniture is used for a long time. It is necessary to protect the surface coating of furniture regularly. It is best to wipe it once every three months with a little wax on the top and bottom of the furniture. The maintenance of such African rosewood furniture not only increases the aesthetics of the furniture, but also protects the wood. Prevent alcohol, oil stains and other solvents from contacting mahogany furniture.
The relevant content of the above-mentioned African rosewood cracking for a few years is briefly introduced here, I hope to help you, more furniture information, all in GO Jiaju Furniture Network

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.
