b. Now which countries do you export your goods?
---Now we export to South East Asia,Africa, North America,South America ect.
- Q:What is the common color of aluminum coil membrane?
- The blue transparent membrane is the most common.
- Q:Can kerosene lubricate and cool aluminum coil when continuous punch?
- Yes, because water and oil are not solute, but they will emulsificate.
- Q:Why there is always impression and indentation on the backup roller of aluminum coil rolling mill with 4 rollers.
- Perhaps there is something wrong in the position controlling the working roller tilt and bend positive and negative convexity, making the working roller out of order and rubbing against the backup roller.
- Q:Why does the coated aluminum coil have thickness requirement for membrane?
- The purpose of coating is to protect the surface of aluminum coil and make it more aesthetic. The thickness of membrane is closely related to the keep years of products made by aluminum coil.
- Q:How to identify the quality of color coated aluminum coil and sheet?
- Color coated aluminum coil is a kind of aluminum coil. As for qualified color coated aluminum coil, the surface has no impression, holiday and damage through the coating, and also no ripple, scratch and swell. All these are easy to see. However, the most important is the color difference of the color coated aluminum coil which is not obvious but will influence the decoration effect. Now the surface of curtain wall aluminum sheet will also be treated with electrostatic spraying. The power coating materials can have dozens of colors and realize good decorative effect, with polyurethane, polyethylene expansion resin and epoxy resin as raw materials, high color retention pigment as auxiliaries.
- Q:What kind of sensor is appropriate for aluminum coil thickness measurement?
- Thickness measurement can be divided into single-point and two-point thickness measurement, the principle of which is to measure thickness of aluminum coil through distance measure sensor. Single-point thickness measurement is to calculate the thickness by measuring the distance between the aluminum coils and then subtracting the distance with fiducial point. Double-point thickness measurement is to calculate the thickness by setting a proper distance between two sensors, putting the aluminum coil between them and measuring the distance and then subtracting the distance with initial distance, which is more accurate than single-point measurement. (Professional thickness measurement sensor is also based on single-point or two-point thickness measurement.) The distance measurement sensor can be divided into laser sensor, eddy current sensor and so on. The measuring range of laser sensor is larger than that of eddy current sensor, but less accurate. The While the accuracy of eddy current sensor is around 0.01%, and the measuring range is around several millimeters to more than ten millimeters.
- Q:Why 5052 turn black after annealing during the production of aluminum alloy?
- It has been sooted.
- Q:How heavy and long is the aluminum rolling on average?
- The blank aluminum coil of aluminum manufacturer is about 5-6 tons, while the aluminum coil of dealer or supplier depends on the feeding frame, about 1.5-2 tons or 3 tons.
- Q:Why does the end face of aluminum coil have grease spots?
- Process one without coolant to see whether there are spots. There is a layer of alumina membrane on the blank face of aluminum coil, which will react with basic coolant when heating through processing.
- Q:How to remove the fingerprint and glue residue on the color aluminum coil?
- Try to use essential balm. We often use the essential balm to remove glue residue on the stainless steel bowl and basin.
