Polycarbonate Hollow Sheet Processing Methods

Polycarbonate Hollow Sheet Processing methods

(1) hydraulic presses: stamping this PC board processing is limited to the thickness of the PC sheet stamping range of 1.5mm or less, if any special requirements, 2mm or even thicker plate can also be stamping. But the rapid increase in the cost of stamping, due to the increase in sheet thickness, tooling cycle will be reduced, the cost of changing the die will increase.

(2) stamping on the PC board material restrictions: PC board stamping process is not only the thickness of the material itself is limited, the same is the plate. In fact, not all of the plate will be used stamping process, attention, stamping on the plate requirements, the plate itself must have a certain toughness Caixing.

(3) the advantages of stamping: PC board stamping mainly because it can be large-scale, mass production, but also to ensure that a large number of production processes, all products can be consistent, so that each product to maintain the same. If the customer chooses a poor plate, there will be many holes on the surface, similar to this situation, it is recommended to use stamping process for processing, can form high-quality PC sheet. In short, in order to make PC board has a good practical effect, stamping processing is a good way.

PC stamina greenhouse greenhouse to maintain a constant temperature environment, so usually in a relatively sealed state, the air humidity is often greater than the outdoor. But too humid environment is not conducive to the growth of certain crops, so the greenhouse air humidity management is mainly dehumidification. Now Shanghai Jie resistance to the board manufacturers to share with you a few tips in this regard:

(A) regular ventilation: before we said, PC stamina greenhouses in the greenhouse so more wet or mainly because of its seal, so proper ventilation is a good way to reduce moisture. But not at any time can be ventilated, must be carried out in the outdoor temperature is relatively high, otherwise it will cause the indoor temperature drop.

(B) to increase the amount of light: increase the amount of light can be increased room temperature, room temperature, often ventilation, to achieve the purpose of reducing humidity.

(C) temperature and humidity: This method can meet the needs of vegetables on the temperature, but also reduce the relative humidity of the air. When the plant grows to have the resistance, the water closes the shed to heat up to about 30 ℃ for one hour, then ventilates and deweses, and can be repeated once more than 4 hours after the shed moisture below 25 ℃.

(D) reasonable watering: moisture is the main factor leading to increased indoor humidity, so how to water has become an important measure to control humidity. Winter and spring production can choose sunny ditch pouring or sub-watering, plastic film can be used under the film dark irrigation. Watering should strictly control the watering, to prevent the indoor humidity is too high. After each watering appropriate release of the wind, in time to draw hoe soil, can reduce soil moisture, can also reduce the air humidity.

(5) plastic film cover: the use of plastic film cover can reduce the evaporation of soil moisture, indoor air humidity is an important measure to reduce. For example, in the solar greenhouse with the size of the distance between the monolithic, plastic film cover double ridge approach, watering water along the mantle under the small ridge into. Plastic film to prevent the evaporation of water, also to prevent the water after the water in the shed a substantial increase in humidity.
