Abstract

The present invention discloses a technique for removing protection film for greenhouse. Said invention includes protection film and film-removing agent. Said protection film includes one alkaline medium, at least two adhesives based on acrylic derivative resin and at least one filler or color matter, and the film-removing agent includes second alkaline medium, the described second alkaline medium is sodium hydroxide, sodium carbonate, sodium ethylene diamine tetrucetate salt and sodium nitrilo triacetate or their mixture. Said invention is applicable to greenhouse surface made of glass, hard plastics or elastic plastics. Besides, said invention also provides the application method of its film-removing agent.

Description

technical field [0001] The present invention relates to removable protective films for greenhouses and their removers. The protective film opacifies transparent or translucent greenhouse surfaces, and this protective film can be removed by a remover. Background technique [0002] In the horticulture industry, many plants are grown in greenhouses to obtain the best environment, such as temperature, light, humidity, etc. The problem, however, is that in warm, sunny weather conditions, plants are exposed to a lot of light radiation. This can disturb its growing conditions and affect its growth and even burn the plant. In order to avoid this situation, in spring and summer, the horticultural industry generally adopts the method of covering the top layer of transparent greenhouse with a protective layer to protect plants from the negative effects of radiation. The main condition to be fulfilled by the covering is that it provides adequate protection of the plants from light an...
