Polyvinyl chloride film,soft,agriculture - Introduction
Soft polyvinyl chloride film is a widely used agricultural material with the following properties:
1. Weather resistance: Soft polyvinyl chloride film has good weather resistance, can resist the erosion of ultraviolet rays, oxygen and moisture, can be used outdoors and maintain good performance.
2. Flexibility: The film has good elasticity and high flexibility, which can be adapted to various shapes and needs in agricultural use.
3. Barrier: The film has good gas and water vapor barrier properties, which can effectively reduce water evaporation and nutrient loss in the soil.
4. Light transmittance: The film has a certain light transmittance, which can adjust the amount of sunlight received by crops and provide a suitable growth environment.
The main uses of soft polyvinyl chloride film in agriculture include:
1. Greenhouse cover: Soft polyvinyl chloride film can be used to cover the top of the greenhouse, adjust the light and temperature, and provide a suitable environment to promote the growth of crops.
2. Land cover: The film can be used to cover the surface of the land, reduce water evaporation and weed growth, increase soil temperature, and maintain soil nutrients.
3. Soil protection: Film can be used to repair and protect damaged land, prevent soil loss and restore soil quality.
The method of manufacturing flexible polyvinyl chloride film usually includes heating and plasticizing polyvinyl chloride resin, and then extruding or calendering it into a flat sheet.
Regarding safety information, the following should be noted when using soft polyvinyl chloride film:
1. Avoid contact with sharp objects: the film is easy to be cut by sharp objects. When using, attention should be paid to prevent contact with sharp objects to avoid damage and safety hazards.
2. Avoid high temperature: Soft PVC film is easy to deform or even melt at high temperature, so avoid exposure to high temperature environment.
3. Proper cleaning and maintenance: regular cleaning and maintenance should be carried out during use to avoid accumulation of dirt and harmful substances on the surface of the film.
