    Aluminum foil polyurethane air duct is a kind of air duct made of polyurethane in the middle and composite aluminum foil on both sides. One of the main characteristics of aluminum foil polyurethane air duct is lightweight, but its biggest deficiency is that the fire performance can not meet the national requirements. The national “code for fire protection of high rise buildings” and “code for fire protection of civil buildings” both stipulate that the ventilation duct materials must be made of class non-combustible materials. Aluminum foil polyurethane air duct can only reach B 1 level at the highest, and its accessories and glue are organic materials, and can only reach B 1 level at the highest, which is not in line with national standards. The poor strength and pressure bearing capacity of the aluminum foil polyurethane air duct are also its major shortcomings. What Is The Ventilation Duct<\/p>\n\n\n\n

    The color steel plate air duct is divided into single-sided color steel and double-sided color steel. The single-sided color steel is to move the original superfine glass wool from the outside to the inside, that is, a layer of color steel from the outside and a layer of superfine glass wool from the inside. The double-sided color steel is to make a layer of iron sheet protection outside the insulation cotton of the iron sheet air duct. There is no great innovation compared with the iron sheet air duct in technology, but it is actually the iron sheet air duct. The improvement point is that PVC insert is used to replace the bite and flange, and the thermal insulation cotton and color steel plate are formed at one time without secondary thermal insulation.

    1. The use of PVC inserts instead of bite and flange makes the iron sheet air duct nondescript. It not only reduces the fire resistance and fire resistance of the air duct (PVC inserts can only reach B1 level) but also makes the advantages of good toughness of the iron sheet completely lost. In order to improve the tightness, it is more reasonable to think about the construction quality or plugging of the iron sheet air duct. What Is The Ventilation Duct<\/p>\n\n\n\n

    2. Glass wool is easy to disperse inside, which affects human health. Both single side and double side color steel plates need to be slotted to make an air duct. The sealing after slotting is a big problem, and it is difficult to seal in place. What Is The Ventilation Duct<\/p>\n\n\n\n

    3. The air duct is not easy to clean. The interior of one side is glass wool, which is not easy to clean. The interior of two sides is color steel plate.

In particular, the outer composite aluminum foil has a high heat reflection ability, and its strength and toughness are much better than aluminum foil, so it is not easy to break. Because the air duct wall is the insulation layer, the pipe adopts a tenon joint, T-shaped inner frame butt joint, and iron sheet plug joint (or outer flange connection), so that all parts of the air duct are evenly insulated without cold bridge phenomenon, and has good thermal insulation performance.

Some data show that the noise elimination capacity of super air duct can reach 18 dB \/ M ~ 21 dB \/ m when the medium frequency is 1 000 Hz ~ 2 000 Hz and the pipe diameter is 500 mm ~ 320 mm. It is a very good pipe type noise eliminator, which can eliminate the primary noise from air-conditioning equipment and the noise from valve body, valve body and air-conditioner With the extension of the pipe, the effect of the secondary noise produced by the pipe fittings is more obvious, so the special muffler can be omitted. However, the galvanized iron sheet air duct and the inorganic glass fiber reinforced plastic air duct have no noise elimination performance, so the muffler should be added.

                        4. Odporno\u015b\u0107 na wilgo\u0107<\/p>\n\n\n\n

                        There are no perishable materials and components in the materials used for the super air duct. The outer surface of the air duct is made of moisture-proof aluminum foil cloth. Its moisture permeability is 0, and it has a strong anti-corrosion ability. The water absorption rate of fiberglass board is not more than 2%. When the pipe is in a humid environment for a long time, its noise elimination and heat preservation properties will not change. Because it is a porous material, it is necessary to prevent the pipe interior, pipe end, an incision from being soaked by water for a long time. The galvanized iron sheet air duct is easy to be affected by moisture, corrosion, and rust, which is more serious when conveying air for air conditioning with large moisture content. Especially when the air duct is made, the galvanized layer at the iron sheet bite is damaged, and it is not easy to make up an anti-corrosion treatment. There will be condensation at the place where the cold bridge is produced, which will cause corrosion to the pipeline, thus affecting its overall life. Due to the restriction of raw material ratio, the stability of moisture-proof ability of inorganic FRP air duct is poor. What Is The Ventilation Duct<\/p>\n\n\n\n

Szybko\u015b\u0107 przecieku powietrza w kanale powietrznym powinna wynosi\u0107 10% (dla og\u00f3lnego uk\u0142adu nawiewno-wywiewnego). Kana\u0142 super powietrza jest po\u0142\u0105czony przez szczelinowanie, czopowanie i klejenie, a z\u0142\u0105cze jest uszczelnione ta\u015bm\u0105 z folii aluminiowej. Wyciek powietrza niewzmocnionego kana\u0142u powietrznego wynosi zasadniczo 0, wska\u017anik przecieku powietrza wzmocnionego kana\u0142u powietrznego nie przekracza 1%, a wska\u017anik przecieku powietrza systemu nie przekracza 2%. Gdy ci\u015bnienie statyczne w rurze wynosi 500 PA, przeciek powietrza na jednostk\u0119 powierzchni kana\u0142u powietrznego jest mniejszy ni\u017c 118 m3\/h \u00b7 m2.<\/p>\n\n\n\n

                          1. Kana\u0142 powietrzny z blachy stalowej ocynkowanej. Jako rodzaj tradycyjnej rury wentylacyjnej, og\u00f3lnie nadaje si\u0119 do projekt\u00f3w HVAC o niskich wymaganiach dotycz\u0105cych warunk\u00f3w \u015brodowiskowych. Nadaje si\u0119 do transportu suchego i niekorozyjnego gazu. W u\u017cytkowaniu, ze wzgl\u0119du na du\u017cy ha\u0142as i efekt izolacji nie mo\u017ce trwa\u0107 d\u0142ugo, na d\u0142u\u017csz\u0105 met\u0119 mo\u017ce by\u0107 stopniowo zast\u0119powany rurami wentylacyjnymi z nowych materia\u0142\u00f3w.<\/li>\n\n\n\n
                          2. Kana\u0142 powietrzny FRP. Jest to rodzaj rury wentylacyjnej, kt\u00f3ra jest p\u00f3\u017aniejsza ni\u017c kana\u0142 powietrzny z blachy ocynkowanej. Posiada w\u0142a\u015bciwo\u015bci przeciwpo\u017carowe i antykorozyjne. Nadaje si\u0119 do stosowania na zewn\u0105trz napowietrznej in\u017cynierii HVAC i \u015brodowiska korozyjnego. Jego wygl\u0105d zosta\u0142 doceniony przez wielu konsument\u00f3w. Jednak ze wzgl\u0119du na rzeczywisty efekt odporno\u015bci na wilgo\u0107 kana\u0142u powietrznego z FRP i og\u00f3ln\u0105 wydajno\u015b\u0107 jako\u015bciow\u0105 nie osi\u0105gni\u0119to oczekiwanego efektu, a poniewa\u017c jego cena jest obliczana wagowo, ta nieuzasadniona metoda wyceny powoduje, \u017ce cena kana\u0142u powietrznego z FRP jest dro\u017csza nie wprost proporcjonalne do jego rzeczywistej warto\u015bci, wi\u0119c liczba u\u017cytkownik\u00f3w spad\u0142a w ostatnich latach.
