鍍鋅鋼板和鍍鋅鐵皮只是一種材質(zhì)！俗稱白鐵皮通風管道。有單面鍍鋅和雙面鍍鋅的，需要根據(jù)實際情況選擇鋅層厚度，表面：有花，無花，有油，無油，鍍鋅通風管道主要看他的鍍鋅板厚度和抗氧化能力(鋅層厚度）。下面濟南鐵皮風管加工人員來講講鐵皮通風管道加工的細節(jié)：

Galvanized steel plate and galvanized iron sheet are just one material! Commonly known as tin ventilation ducts. For single-sided and double-sided galvanized pipes, the thickness of the zinc layer needs to be selected based on the actual situation. The surface: with or without flowers, with or without oil. The galvanized ventilation pipeline mainly depends on the thickness of the galvanized sheet and its oxidation resistance (zinc layer thickness). Next, Jinan iron sheet air duct processing personnel will talk about the details of iron sheet ventilation duct processing:

1、板材接縫處從一端另一端按對中位置粘上壓敏鋁箔膠帶,壓敏膠帶粘在一邊的寬度不小于20mm。

1. Stick pressure-sensitive aluminum foil tape from one end to the other end at the seam of the board according to the alignment position, and the width of the pressure-sensitive tape adhered to one side shall not be less than 20mm.

2、清潔板材切割面的粉末,按空調(diào)風管加工任務單檢查風管面板是否符合設(shè)計要求。

2. Clean the powder on the cutting surface of the board, and check whether the air duct panel meets the design requirements according to the air conditioning duct processing task sheet.

3、清潔板材切割面的粉末、油漬、水漬、灰塵,用毛刷在切割面上涂刷膠粘劑。

3. Clean the powder, oil stains, water stains, and dust on the cutting surface of the board, and use a brush to apply adhesive on the cutting surface.

4、將風管面板按設(shè)計要求粘合,待涂膠不粘手時.并用刮板壓平.對難以刮平的局部,可用木錘輕輕錘平。

4. Glue the air duct panel according to the design requirements, and when the adhesive does not stick to the hands, use a scraper to flatten it. For areas that are difficult to flatten, use a wooden hammer to gently flatten them.

5、檢查板材接縫粘接是否達到質(zhì)量規(guī)定。

5. Check whether the joint bonding of the board meets the quality requirements.

制作工藝要求

Production process requirements

1、白鐵皮風管加工宜選用壓槽連接或焊接，不能焊接。

1. The processing of white iron sheet air ducts should choose groove connection or welding, and welding is not allowed.

2、風管實木板材拼接的咬口縫應分離，不能有十字型拼接縫。

2. The bite seam of the solid wood panel splicing of the air duct should be separated and there should be no cross shaped seam.

3、咬口縫緊密、總寬一致，壓邊垂直，弧型均勻且兩側(cè)面垂直面。

3. The bite seam is tight, the overall width is consistent, the edge pressing is vertical, the arc shape is uniform, and both sides are perpendicular.

4、通風風管無明顯扭曲與翼角，表面應整理平整，凹凸不能超過8mm。

4. The ventilation duct should have no obvious distortion or wing angles, and the surface should be neat and flat, with no more than 8mm bumps.

5、通風風管孔徑或外邊長容許誤差為負偏差，當通風風管大直徑小于等于630mm時，為-1mm；當超出630mm時，為-2mm。

5. The allowable error for the aperture or outer length of the ventilation duct is a negative deviation. When the large diameter of the ventilation duct is less than or equal to 630mm, it is -1mm; When it exceeds 630mm, it is -2mm.

6、立管平面度的容許誤差為1mm，矩形通風風管二根平行線長度差值不能超出2mm。

6. The allowable error in the flatness of the riser is 1mm, and the difference in length between the two parallel lines of the rectangular ventilation duct cannot exceed 2mm.

7、不銹鋼風管直徑超出630mm、隔熱保溫保溫風管直徑超出800mm，管一段距離超出1250mm或低壓通風風管一側(cè)平占地面積超出1.2㎡、中、高壓通風風管超出1.0㎡，都應選用固定不動防范措施。還有什么事項就來我們網(wǎng)站http://rdhw.com.cn咨詢吧！

7. Stainless steel air ducts with a diameter exceeding 630mm, thermal insulation and insulation air ducts with a diameter exceeding 800mm, a distance exceeding 1250mm, or a flat area on one side of the low-pressure ventilation duct exceeding 1.2 square meters, or medium and high-pressure ventilation ducts exceeding 1.0 square meters, all should adopt fixed and immovable prevention measures.
