About the development of vegetable greenhouse insulation in recent years

Traditional thermal insulation covering materials, including straw, mats, paper quilts and quilts, thermal insulation felts, etc. It also reduces the thermal insulation performance, and seriously pollutes the film, which can easily reduce its light transmittance. The current development of new thermal insulation has made corresponding progress in overcoming the above-mentioned defects. The ideal thermal insulation quilt should have the advantages of small heat transfer coefficient, good thermal insulation, moderate weight, easy to roll and unwind, good windproof, waterproof, long service life, etc. It is suitable for the use of roller shutter machines. Vegetables and vegetable greenhouses can be heat-insulated and processed. Camping tents and protective covers of various machinery and equipment can be used to cover open-air warehouse stacks in stations, docks, seaports, and airports. The freight tarpaulins of cars, trains and ships can be used as materials for building temporary sheds and temporary warehouses on various construction sites such as construction sites, power construction sites, etc. It can be used to build temporary granaries and cover various crops in the open air. Material: fireproof cloth, canvas, pvc cloth, oxford cloth, felt, glass wool, rock wool Features: good thermal insulation effect, light weight, easy to use and move, durable. The vegetable greenhouse is resistant to acid and alkali, does not mold, has good traffic, and is easy to store. The insulation is made of insulating wool fiber and chemical fiber raw materials. In the process of material selection, attention should be paid to the functions of ultraviolet radiation and chemical reaction resistance, which solves the problem that the straw mountain cannot solve the problem of being afraid of acid and alkali, afraid of humidity and mildew, and the greenhouse is insulated and light, and the storage is convenient. . The vegetable greenhouse insulation quilt should have the characteristics of heat preservation, light transmission, moisture resistance, easy retraction and long service life. With the rapid development of the greenhouse planting industry, insulation blankets are gradually being accepted by farmers. Insulation is used as a greenhouse“cotton coat”, While raising the temperature of the greenhouse, it also contributes to enriching people's dining table in winter! In the process of material selection, the vegetable greenhouse insulation quilt pays attention to the functions of anti-ultraviolet and anti-chemical reaction, anti-rain and snow, anti-aging, anti-corrosion, high tensile strength, strong anti-penetration ability; large extension force, flame retardant Strong stability, high temperature resistance, no cracks, low temperature resistance and no breakage. Install canvas circles on the four sides of the thermal insulation quilt. The normal hole distance is about 200cm and one hole (free), and the quilt and the quilt can be tied together with a belt or rope. This product has the properties of heat preservation and temperature increase, cleanliness, cleanliness, large friction coefficient, light weight, simple construction and low cost. Under the same conditions, the temperature can be increased by about eight degrees compared with the use of straw curtains. Alternative to other fabric quilts. In recent years, the use of greenhouse vegetables as seedbeds has developed rapidly. However, vegetables are not resistant to continuous cropping, and at the same time, they are cultivated all year round. Due to the reduction of heavy brushing and leaching of rain, the salt in the soil in the greenhouse accumulates more and more, which has a greater impact on vegetables. Therefore, if there is no plot for rotation, it can be used to cultivate and cultivate flowers, and it can also be used to cultivate overwintering sweet potato seedlings. 1. Consciousness: Greenhouse and greenhouse growers are not very aware of the use of thermal insulation quilts, which limits the use of thermal insulation quilts in vegetable greenhouses to a corresponding extent. The thermal insulation quilt has many advantages. It can protect the shed film and promote the development of crops. We still recommend users to use the thermal insulation quilt. Second, the price: Compared with thermal insulation materials such as grass felt, the price of thermal insulation quilts is higher, and it needs to install a roller shutter machine, which is costly. 3. Thermal insulation: Its thermal insulation is affected by many factors, and usually requires more maintenance, which affects its promotion. The rapid development of greenhouse and vegetable greenhouse insulation in recent years has brought great help to the greenhouse and greenhouse vegetable planting industry, and has made great contributions to the economic development of farmers. However, the hot development of vegetable greenhouse insulation has also disrupted the market. Our factory direct sales, quality assurance, reasonable price, construction insulation quilt has a variety of specifications, and can also be processed according to customer requirements. Construction thermal insulation quilts, tarpaulins, thermal insulation curtains can be used for construction thermal insulation, engineering thermal insulation, concrete thermal insulation and anti-freezing and other engineering construction; can also be used for landscaping maintenance, urban greening and anti-freezing, greenhouse thermal insulation, farm thermal insulation, automobile anti-freezing, truck thermal insulation , Goods cold and frost protection, household and supermarket insulation and other purposes.

In the present growing world of emerging technology, the has demanding operation in various sectors like clear pvc film, pvc plastic film, clear pvc film and many other industries at pvc plastic film levels of manufacturing and designing.

ZHONGSHAN LINYANG PLASTIC CO.LTD works hard to enhance continuously our reputation for accessibility, professionalism, performance, and the depth and quality of our long-term consultative relationships with clients.

If ZHONGSHAN LINYANG PLASTIC CO.LTD added selling plans, offered more PVC Film, and increased service regions, it would suit the needs of more users.

When selecting the best products for customers, we considered not only the PVC Tarpaulin, but also the clear pvc film.
