With the development of environmental protection and energy conservation, people pay more and more attention to the installation of smoke exhaust pipes, but many people are laymen. It will provide an opportunity for some dark workshop poor smoke exhaust pipes to find some small workshop smoke exhaust pipes on the street.

　　如果構建公民想知道他買排煙通風管道質(zhì)量是否通過一個標準的,簡單的方法就是打煙管道壁,合格的煙窮竭通風管道,它的煙管道壁厚達到1.5厘米,當煙管道壁相應的不同的地方,聲音是一致的,泥濘的固體,清脆。如排煙通風管道較差，由于管壁厚度不均勻，不同位置的敲擊聲不一致。

　　If the construction citizen wants to know whether the quality of the smoke exhaust ventilation pipe he bought has passed a standard, the simple method is to hit the smoke pipe wall. The qualified smoke exhaust ventilation pipe has a wall thickness of 1.5cm. When the smoke pipe wall is corresponding to different places, the sound is consistent, muddy solid and crisp. For example, the smoke exhaust and ventilation pipes are poor, because of the uneven thickness of the pipe wall, the knocking sound at different positions is inconsistent.

　　煙道機的性能好壞直接決定了排風風道的質(zhì)量，一臺好的煙道機可以生產(chǎn)出一臺好的排風風道，一臺好的排風風道可以有一個好的，這是一個很好的邏輯去理解。排煙通風管道是以抗堿高強度玻璃纖維布為增強材料的水泥砂漿的薄壁構件。水泥采用強度等級不低于32.5的快硬硫鋁酸鹽水泥或低堿度的硫酸鹽水泥。中砂應使用。在煙道運輸安裝有可靠措施保證煙道無裂紋的前提下，不采用加勁隔板。

　　The performance of the flue fan directly determines the quality of the exhaust air duct. A good flue fan can produce a good exhaust air duct, and a good exhaust air duct can have a good price, which is a good logic to understand. Smoke exhaust and ventilation pipe is a thin-walled component of cement mortar with alkali resistant high-strength fiberglass cloth as reinforcement material. The cement shall be fast hardening sulphoaluminate cement with strength grade no less than 32.5 or sulfate cement with low alkalinity. Medium sand shall be used. On the premise that reliable measures are taken to ensure that the flue is free of cracks during transportation and installation, stiffening baffles are not used.
