散裝物料的輸送。在一些通風(fēng)管道加工工廠的生產(chǎn)過(guò)程中，需要輸送松散的顆粒，特別是比例較小的螺旋風(fēng)管，如發(fā)泡塑料顆粒，成本低，效果好。螺旋風(fēng)管是一種薄壁管，由金屬帶材卷制而成，圓形，無(wú)焊接，無(wú)漏氣，無(wú)漏水，多用于送風(fēng)和散裝物料輸送，而不是傳統(tǒng)的白鐵管(即手工咬鐵管)。它是一種風(fēng)管，全機(jī)制，直管不需要手動(dòng)敲擊。

Transportation of bulk materials. In the production process of some ventilation pipe processing plants, loose particles need to be transported, especially spiral air ducts with small proportion, such as foamed plastic particles, which have low cost and good effect. The spiral air duct is a kind of thin-walled pipe, which is rolled from metal strip, round, non-welded, non-leaking, non-leaking, and mainly used for air supply and bulk material transportation, rather than the traditional white iron pipe (i.e. manual bite iron pipe). It is a kind of air duct with full mechanism. The straight pipe does not need to be knocked manually.

鍍鋅螺旋風(fēng)管指酒店、、紡織、化纖、石油化工、機(jī)械制造、儀表、電子、醫(yī)藥、煙草、食品、倉(cāng)儲(chǔ)、寫(xiě)字樓及地鐵、人防、地下室等工程的送風(fēng)、排風(fēng)、排煙管道。它的厚度和規(guī)格可根據(jù)需要而變化，通常在連接時(shí)，鍍鋅螺旋風(fēng)管的兩端都要外接。

Galvanized spiral air duct refers to the air supply, exhaust and smoke exhaust pipes of hotels, shopping malls, textiles, chemical fiber, petrochemical, machinery manufacturing, instruments, electronics, medicine, tobacco, food, storage, office buildings, subways, civil air defense, basement and other projects. Its thickness and specification can vary according to needs. Generally, both ends of galvanized spiral air duct shall be externally connected when connecting.

由于鐵皮加工在不同環(huán)境下容易發(fā)生反應(yīng)，導(dǎo)致腐蝕和生銹。鋅在干燥的空氣中基本沒(méi)有變化。在潮濕的空氣中，鋅表面會(huì)產(chǎn)生致密的堿性碳酸鋅膜，因此在風(fēng)管鐵皮上鍍一層鋅可以保護(hù)鐵皮。鍍鋅處理鈍化、染色或涂上護(hù)光劑后，可加強(qiáng)其保護(hù)性和裝飾性。

The iron sheet processing is prone to react in different environments, resulting in corrosion and rust. Zinc basically does not change in dry air. In humid air, a dense alkaline zinc carbonate film will be formed on the zinc surface, so a layer of zinc on the iron sheet of the air duct can protect the iron sheet. After passivation, dyeing or application of light protection agent, zinc plating can enhance its protection and decoration.

通風(fēng)管道加工的過(guò)程中應(yīng)該盡量避免出現(xiàn)縱向接縫，但是一定不能出現(xiàn)橫向接縫。而且通風(fēng)管道的咬口縫和四角的縫隙處，需要按照設(shè)計(jì)潔凈等級(jí)要求，然后還要采用密封膠將其堵嚴(yán)。另外通風(fēng)管道板材的連接縫的密封面應(yīng)該設(shè)在通風(fēng)管道壁的正壓側(cè)。

The longitudinal joints shall be avoided as far as possible during the processing of ventilation pipes, but the transverse joints must not occur. In addition, the seam of the ventilation pipe and the gap at the four corners need to be sealed with sealant according to the design cleanliness level. In addition, the sealing surface of the connection joint of the ventilation pipe plate should be set at the positive pressure side of the ventilation pipe wall.

加工的時(shí)候，不能在通風(fēng)管道內(nèi)部設(shè)置加固框或者加固筋，因?yàn)檫@樣對(duì)于通風(fēng)管道的質(zhì)量會(huì)造成一定的影響。

During processing, the reinforcing frame or reinforcing bar cannot be set inside the ventilation duct, because this will have a certain impact on the quality of the ventilation duct.

通風(fēng)管道加工不能采用S型插條和C型直角插條的連接方式，另外對(duì)于一些特殊的通風(fēng)管道來(lái)說(shuō)，還不能采用按扣式的咬口。

The connection mode of S-type and C-type right-angle inserts cannot be used for the processing of ventilation pipes. In addition, for some special ventilation pipes, the snap bite cannot be used.

通風(fēng)管道制作完畢之后，還要用清洗液進(jìn)行清洗，只有達(dá)到清洗標(biāo)準(zhǔn)之后，才可以及時(shí)封口。

After the fabrication of the ventilation pipe, it should be cleaned with cleaning fluid. Only after the cleaning standard is met can it be sealed in time.

玻璃纖維復(fù)合板風(fēng)管端口為切割面時(shí)，在裝配法蘭連接件前應(yīng)將管端切口面用膠帶或膠液進(jìn)行封堵，才能防止玻璃纖維外露和飛散

When the air duct end of the glass fiber composite plate is the cutting surface, the cutting surface of the pipe end shall be sealed with adhesive tape or glue before assembling the flange connector, so as to prevent the exposure and dispersion of the glass fiber
