Problems solved by technology

Although this method enhances the tensile performance of the plastic film to a certain extent by compounding a plurality of parallel cables on the plastic film, yet, because it only uses two layers of plastic film layers to tightly bond the cables Wrapped, the cable can slide, and the plastic film cannot be driven at the same time when the cable is pulled. If the greenhouse film is partially wrinkled or uneven during use, it is still necessary to pull the plastic film itself to remove the wrinkle or unevenness. Therefore, there is still the problem of poor tear resistance; at the same time, due to the relatively large overall area of ​​the film, it is not easy to transport or pull during processing, and the use of multi-layer films makes the processing process more complicated. The requirements are also increased accordingly, which is not conducive to practical operation and other issues.

Abstract

The invention relates to a manufacturing method of a greenhouse thin film, belongs to the technical field of agricultural materials, aims to solve the problem that an existing greenhouse thin film is poor in pulling resistance, and provides the manufacturing method of the greenhouse thin film. The method comprises the following steps: enabling a plurality of plastic film pressing belts and plastic thin films to synchronously move towards different procedures under the effect of a traction force, wherein the plastic film pressing belts are parallel to one another, and the plastic film pressing belts are flat; enabling each plastic film pressing belt and the corresponding plastic thin film to be subjected to thermal combination treatment by a thermal combination procedure; enabling the heating temperature of a side of each plastic film pressing belt to be 220-240 DEG C; enabling the heating temperature of a side of each plastic thin film to be 160-190 DEG C; and cooling every plastic film pressing belt and the corresponding plastic thin film after every plastic film pressing belt and the corresponding plastic thin film are subjected to thermal combination integrally so as to obtain the corresponding greenhouse thin film. The binding fastness of every plastic film pressing belt and the corresponding plastic thin film is improved integrally, and therefore, the pulling resistance is improved.

Description

technical field [0001] The invention relates to a production method of a greenhouse film, belonging to the technical field of agricultural materials. Background technique [0002] Agricultural greenhouse technology has been widely used in agricultural production in most areas of our country, and plastic film is a commonly used material in agricultural greenhouses. However, due to the soft material of plastic film and relatively poor tensile resistance, when used in greenhouses Due to the large area of ​​the greenhouse film, it is easy to cause damage, resulting in poor actual use effect. Therefore, most of the existing greenhouse films are supported by rigid frameworks. On the other hand, because the greenhouse film is often repeatedly pulled or tightened during use and construction, and the plastic film alone has relatively poor tensile strength and softness, it is difficult to be tensioned, and excessive force On the contrary, it will damage the film of the greenhouse. ...
