Answer 1: First, observe the color The entire curtain, including the leaves and all fittings (wire racks, adjustment bars, pull lines) and the small accessories on the adjustment bar must be kept in the same color, which indicates that the production process has passed, and the quality of the curtains is also good.
Second, check the degree of smoothness by hand to feel the smoothness of the blade and wire frame, the quality of a good product should be smooth, smooth edges, no sense of stingy hands.
Third, open the curtains, test the opening and closing of the blade function Turn the adjustment blade to open the blade, the leaves should maintain a good level of degree, that is, the spacing between the leaves is symmetrical, the leaves remain flat, no sense of bending up and down. When the leaves are kept closed, the leaves should fit together without any light leakage.
Fourth, check the degree of deformation resistance After the blade is opened, you can use the hand to force the blade downwards to force the blade to bend down, and then quickly release it. If the blades quickly return to the horizontal state, no bending occurs, indicating that the quality is acceptable.
Fifth, test automatic locking function When the leaves are all closed, pull the cable, you can roll up the blade. Pull the cable to the right at this time, the blade should be automatically locked to maintain the corresponding rolled up state, neither continue to roll, nor loose. Otherwise, there is a problem with the locking function.
Answer 2: Tip 1: Look at the quality of the blinds is an important part of adjusting the shutters. When choosing blinds, it is best to first check if the shutter blades are smooth and even, and see if each blade will have a burr. In general, high-quality blinds are better handled in the details of the blade, especially the blinds made of plastic, wood, bamboo, if the texture is good, then its service life will be longer. The adjustment lever is also a key part of the blinds to be examined. The adjustment bar of the blind has two functions. One is to adjust the shutter of the shutter and the other is to adjust the angle of the blade. When checking the adjusting lever, first pull the blinds flat and try to see whether the lifting switch is smooth and then turn the adjusting lever to see if the turning of the blades is also flexible. Tip 2: The size shutters are equipped with concealed and wall mounted installations. When purchasing, the size of the shutters needs to be measured according to different assembly methods. The shutters concealed in the window panes should have the same length as the windows, but the width should be reduced by 1 to 2 centimeters from the left and right of the window. If the blind is hung outside the window, its length should be about 10 cm longer than the height of the window, and it should be 5 cm wider than the width of both sides of the window to ensure that it has a good shading effect. In general, dark rooms such as kitchens and toilets are equipped with concealed blinds, while large rooms such as living rooms, bedrooms, and study rooms are more suitable for use with exposed blinds.
