u003cpu003eThe installation of smoke exhaust duct
s is getting more and more attention nowadays. Because many people are laymen, they just find some small workshops on the street to make ventilation ducts, which will provide some black workshops with a way to make inferior exhaust ducts. Take the opportunity. 'When the citizens buy a house in the future, they should not only pay attention to the quality problems on the surface of the house, but also the invisible quality problems.' Ventilation duct manufacturers remind everyone that in accordance with the current national standards, the wall thickness and fire resistance of the smoke exhaust duct There is a complete set of testing methods for performance, but only authoritative testing departments have the ability to do these methods. u003c/pu003eu003cpu003eIf citizens want to know whether the quality of the smoke exhaust pipes of the houses they buy pass the test, teach you a trick, the way is to tap the flue wall, 'Qualified smoke exhaust ventilation pipes, the flue wall thickness of 1.5 Centimeters, so when striking different parts of the flue wall, the sound is consistent, and it is relatively solid and crisp.u003c/pu003eu003cpu003eu003c/pu003eu003cpu003eIf it is a low-quality smoke exhaust duct, the wall thickness is not Even, the sound produced by tapping it at different positions is inconsistent.” Ventilation duct manufacturers tell everyone that if the installation of smoke exhaust ducts is paid attention to by the owner, then there will be no market for inferior flue ducts. u003c/pu003eu003cpu003eThe performance of the flue machine is good or bad directly determines the quality of the exhaust duct. A good flue machine can produce a good ventilation duct, and a good exhaust duct can have a good price. This is very Well understood logic. u003c/pu003eu003cpu003eThe smoke exhaust duct is a thin-walled cement mortar component reinforced with alkali-resistant high-strength glass fiber mesh cloth. The cement should be made of fast hardening sulphoaluminate cement or Low-alkalinity sulfate cement uses medium sand, and the ratio of cement to sand is 1 flue gas duct wall thickness should be uniform. u003c/pu003eu003cpu003eUnder the premise of reliable measures to ensure that the flue gas duct does not appear to be cracked during the flue gas duct transportation and installation, the reinforced rigid partition may not be used. u003c/pu003eu003cpu003eWith more than 10 years of rich experience, we specialize in the production of exhaust and ventilation ducts, black and white iron design, processing, production and installation through-train service.
