1. When designing and installing the connecting channel, a pair of shut-off valves can be added between the magnetic flap level gauge and the mounting interface. This seems to add a little cost to the valve, but the effect is very large, which is convenient for future maintenance, cleaning and overhaul. It can also be safely and conveniently replaced when the level gauge fails.
2. The level gauge must be vertical during use. If it is inclined, it will cause the magnetic float element to rub against the inner wall of the measuring tube, and the wear of the component will affect the use effect and may cause measurement errors.
3. After each internal cleaning of the liquid level gauge, pay attention to slowly let the liquid in the measured container flow into the measuring tube. The excessively fast flow rate will impact the floating ball. If it is serious, the floating ball may be damaged, resulting in the inability to measure. The consequences of the liquid level.
4. Various situations may occur during the industrial production process. Because of the special working principle of the magnetic flap level gauge, special attention should be paid during production. Do not stack magnetically charged electrical appliances or raw materials near the liquid level gauge. It will directly lead to inaccurate measurement data, and will seriously damage the magnetic properties of the original internal components, making it impossible to use normally.
5. The operator should pay close attention to the occurrence of liquid leakage during daily use. The components of the liquid leakage part should be replaced in time to prevent the leakage of the medium to cause corrosion damage to the liquid level gauge.
6. When the measured medium has a precipitation phenomenon, it is necessary to periodically discharge and clean the magnetic flap liquid meter. Excessive deposits can cause errors in the measurement data and result in a shortened life of the level gauge.
7. When encountering a fault, do not handle it yourself without preparation. Be sure to repair it after understanding the cause. If you do not understand the situation, you can consult the manufacturer. Otherwise, damage to the level gauge component will not be worth the loss. .
8. When the remote transmission type magnetic flap level gauge is bundled, it must be noted that it is forbidden to use the iron material for bundling reinforcement. The result of this will make the liquid level gauge not work properly.
In the silicone industry, to meet the user experience of the majority of consumers, multi-color products have always been the best-selling products, the process is used in silicon materials bonding and plastic bonding.
1. Soft and hard plastic two-color design
The two materials must have a certain temperature difference in the melting point. Generally, it is recommended to reach 60°. It is recommended to be at least 30°. The melting temperature of the first shot material is high. Generally, the first shot is PC or PC/ABS, and the second shot is TPU or TPE, PC thickness is 0.6-0.7mm, soft rubber part thickness is required to be 0.4mm or more.
Try to widen the contact area, make grooves to increase the adhesion, or use the core for the first shot, and the second part of the material is injected into the first shot. The surface of the first shot is as rough as possible.
2. Material compatibility
Multi-color injection molded mating materials must meet two basic compatibility conditions. They are compatible with the adhesive compatibility and processing.
3. Transparent and non-transparent two-shot design
(1) Double shot design of small lenses
The first shot is non-transparent, and the second shot is made of a lens. The first shot uses a PC with a high melting point and the second shot uses a PMMA.
(2) Transparent and non-transparent bijective design for decoration
The first shot is a non-transparent material, the second shot is a transparent material, and the non-transparent material is generally a high temperature of the PC material of SABIC, and the second shot transparent material is PMMA or PC. The PC needs to be sprayed with UV to protect it. PMMA can choose uv or fortification. If there are characters on the surface, you must choose UV
In the silicon bonding area, several silicon materials will be used to achieve different color silicon, different rubber components, so the multi_k color process is commonly used and is quite popular.
