In addition to the traditional insulation was outside, Pingliang custom insulation was, insulation was China's large manufacturers have been constantly committed to research and development of new plastic greenhouse insulation was material. Currently the most widely used, there are two types of materials: one with insulation blankets for insulation core, Jinchang custom insulation was, on both sides plus waterproof protective layer; second is to use foamed polyethylene material. They are inexpensive, can make full use of industrial waste, to achieve the recycling of resources, it is an environmentally friendly material. But this material is due to the different sources of raw materials, product performance differences large, especially the sewing needle surface insulation was there when a lot of products, these needle and some may do a water treatment, but most products are not waterproofed, celebrate Yang custom insulation was, or even before the products manufactured to the water treatment, after a period of time, due to the insulation was often performed reel and pull the job, so basically not waterproof eye of a needle to keep intact. The paper is the first to be used in conjunction with grass thatch insulation is material. Paper Source is mainly old cement bags, the development of ordered directly from the paper mill, but the latter costs much higher than the former. Use paper is mainly to prevent the spread of the grass thatch grass thatch pierced below the plastic film, and the formation of a dense layer of insulation between the grass thatch and plastic film, so that greenhouse insulation performance has been further improved. It is measured in the cold winter, with 4-6 layers of old cement bags and five centimeters thick paper is used in conjunction with grass thatch greenhouse indoor temperatures than can be used alone to improve grass thatch 7 ℃ to 8 ℃. But paper is the same as the grass thatch, after being soaked in rain, snow, heat a sharp decline in performance, and are easily damaged. If the paper is when sewn, custom insulation was, surface or add a layer of grass thatch reed, made of grass thatch like shape, the insulation effect is the same, and not easily damaged. Tianshui custom insulation was, Tian Yun vegetable wholesale (certified), custom insulation was planted by the Cangshan County Tianrun professional cooperatives. Cangshan County Tianrun planting cooperatives (www.tianrun8.net) Shandong Linyi, fruits leaders, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Run vegetable wholesale leadership in the field with the staff warmly welcome all inquiries negotiations to create Tianrun vegetable wholesale better future.
