China's waterproof materials have developed into many names today. Flexible waterproof materials are classified into two categories according to their adherence to the waterproof base layer, namely: waterproofing of coils and waterproofing of coatings.
When the ancient poet Du Fu described the leaking roof, he once lamented the "long night's wet and wet", which shows that the leaking roof caused people to suffer from difficulties. Then he had "there are thousands of buildings in the world. "The beautiful imagination, now the beautiful scenery of the poet has become a reality, but the wind and rain still puzzled the builders of the vast buildings."
The development of waterproof materials can be described as a wide variety of today. Flexible waterproof materials are classified into two categories according to the form of their attached waterproof base layer, namely: waterproofing of coils and waterproofing of coatings.
However, the waterproof material is transformed into a waterproof layer, and a key link in the middle is construction - that is, secondary processing of the waterproof material.
What are the characteristics of SBS waterproofing membranes and coatings waterproofing? The following questions about how to choose waterproof materials and waterproof construction are as follows:
The earliest traditional waterproofing membrane should be regarded as paper linoleum. When using linoleum as waterproof layer, it must be bonded with construction asphalt. The upper sandstone: the general practice is three oil two felt or four oil three felt, because of the above labor intensity The construction technology is difficult to hold. When the asphalt is prepared, a large amount of exhaust gas is seriously polluted to the environment. It is impossible to construct in places where fire cannot be used. Fire and burn accidents are easy to occur, and secondary maintenance of the roof is difficult. For the above various reasons, the asphalt is represented by the waterproof layer of linoleum. Currently basically eliminated.
The new generation of waterproof materials is light in weight, convenient in construction, non-polluting to the environment, durable, and beautiful in color direction. Therefore, there are paper-proof linoleum-rubber coil-coated laminating modified asphalt coils. ——All kinds of synthetic polymer waterproofing membranes; coating waterproofing materials are developed from modified emulsified asphalt-plastic ointment-polyurethane waterproof coating to environmentally friendly synthetic polymer color waterproof coating.
The development of waterproof materials can be described as a wide variety of products. In short, the advent and application of various waterproof materials have their own advantages, or the materials are easy to obtain, or the bottom price is earned, or the price is not durable but durable, or the use is not waterproof. Different; the selection of waterproof materials, in addition to cost, climate, geography, building functions, environmental protection, the construction of the building is an important factor; if it is suitable for waterproofing coils, it is not suitable for waterproofing with paint, suitable for coatings. It is not suitable for coils; it is not suitable for the waterproofing of coils: wet base, poor drainage or water-filled parts, uneven base and many embedded bases, water-repellent backwater, water-repellent waterproof, Areas with large typhoons and long-term typhoons; the following base layers are not suitable for waterproofing of paints: waterproofing of wooden sloping roofs.
Insecticide Imidacloprid 95% has special efficacy against pests with
piercing-sucking mouth such as aphids, rice planthopprs,
whiteflies, leafhoppers and thrips.
2.In addition, insecticide Imidachloprid can efficaciously prevent
and kill coleopterous, dipterous and lepidopterous pests such as rice borers,
rice leaf bettles, rice weevils, citrus leaf miners and potato bettles etc.
3.Because of the excellent systemic activity and the relatively low rate of
application of this new insecticide, the active ingredient can be used as
seed dressing as well as for foliar and soil treatment.
