Because waterproof insulation is required Uncovery day, frequent unwinding and pull the insulation work was causing the needle is too large, then the needle is too large have risks? Today, we briefly introduce. Waterproof insulation at the eye of a needle will be seepage, if it rains or snows weather, rain and snow will be very easy to enter into the waterproof insulation is insulation building insulation core is allowed to damp insulation core, and reduce its thermal insulation properties, and some of the materials are waterproof insulation material is waterproof, so water entering the insulation core can not be discharged through the eye of a needle. So easy to make long-term use waterproof insulation was lost due to damp insulation properties, affecting the normal growth of the crop. Needle felt after the insulation was "needle felt" is broken with the old line (cloth) and other materials must be treated by re-pressed, and low cost wholesale insulation was good insulation properties. Needle felt insulation was used as the main needle felt cold insulation materials, (you can also use aluminum film on one side and white polyester fabric sewn fabric cooperation), the use of suture material. This insulation was to be heavier than their own weight composite insulation, wind performance and better insulation properties. Its biggest drawback is that the water is poor. But if the show to spend Oxford waterproof cloth, made of water-resistant insulation can be, the other special insulation was before the insulation is retractable to save, you need a large space to dry, you can save only after dry. Electric insulation was widely St. agricultural machinery (certified), insulation is provided by the Canton of St. Shouguang Agricultural Machinery Co., Ltd .. Shouguang City, Canton St. Agricultural Machinery Co., Ltd.
