濟(jì)南風(fēng)管加工共板法蘭主要由角碼、法蘭夾具和法蘭連接，與風(fēng)管連接成一體。雖然這種風(fēng)管成本低(角鋼消耗減少，制作角鋼法蘭的人工消耗減少)，但實(shí)際應(yīng)用中不如角鋼法蘭，漏風(fēng)率也大，一定用機(jī)床加工。
Jinan air duct processing plate flange is mainly composed of corner code, flange clamp and flange connection, which is integrated with the air duct. Although the cost of this kind of air duct is low (the consumption of angle steel is reduced, and the labor consumption of making angle steel flange is reduced), it is not as good as angle steel flange in practical application, and the air leakage rate is also large, so it must be processed by machine tool.
手工制造很難實(shí)現(xiàn)其生產(chǎn)，通常只用于新風(fēng)系統(tǒng)、空調(diào)系統(tǒng)等。排風(fēng)系統(tǒng)通常采用角鋼法蘭連接，但人防工程不允許采用普通法蘭板連接，那么濟(jì)南通風(fēng)管道制作基礎(chǔ)是什么?下面，讓我們一起來(lái)詳細(xì)了解一下。希望能幫到您。
Manual manufacturing is difficult to achieve its production, usually only used for fresh air system, air conditioning system and so on. The exhaust system usually adopts angle steel flange connection, but the civil air defense project does not allow the use of ordinary flange connection, so what is the foundation of Jinan ventilation pipe? Next, let's have a detailed understanding. I hope I can help you.
Jinan ventilation pipe processing
濟(jì)南通風(fēng)管道廠家發(fā)現(xiàn)，在加工制造風(fēng)管的過(guò)程中，對(duì)材料的要求相當(dāng)苛刻。當(dāng)風(fēng)道表層為鋁箔時(shí)，為了保證表層不容易損壞，規(guī)定了鋁箔的材質(zhì)和厚度，規(guī)定了鋁箔與增強(qiáng)材料復(fù)合的風(fēng)道表層鋁箔的厚度。
Jinan ventilation duct manufacturers found that in the process of processing and manufacturing air duct, the requirements for materials are quite harsh. When the surface layer of air duct is aluminum foil, in order to ensure that the surface layer is not easy to be damaged, the material and thickness of aluminum foil are specified, and the thickness of aluminum foil on the surface layer of air duct compounded with reinforced material is specified.
非金屬風(fēng)管材料發(fā)展迅速，種類繁多，因其特點(diǎn)和優(yōu)勢(shì)而得到廣泛應(yīng)用。為確保使用，根據(jù)工程需要，建議由這些材料制成的風(fēng)管應(yīng)具有不燃性或阻燃B1燃燒性能，面層一定為不燃性材料。
Nonmetallic duct materials have been widely used because of their characteristics and advantages. In order to ensure the safety of use, according to the needs of the project, it is suggested that the air duct made of these materials should have non combustible or flame retardant B1 combustion performance, and the surface must be non combustible materials.
根據(jù)我國(guó)多年的工程應(yīng)用實(shí)踐和產(chǎn)品現(xiàn)狀，規(guī)定了熱敏膠帶和壓敏膠帶的剝離強(qiáng)度試驗(yàn)低值和鋁箔厚度，要求膠帶寬度不小于50毫米，以防止所用膠帶不能滿足管壁密封強(qiáng)度和風(fēng)管的使用壽命。熱敏膠帶的優(yōu)點(diǎn)是它依靠熱熔粘合，只要不加熱，粘合表面在常溫下固化，并且具有牢固的粘合強(qiáng)度。
According to the engineering application practice and product status in China for many years, the low value of peel strength test and aluminum foil thickness of thermal tape and pressure-sensitive tape are specified, and the width of tape is required to be no less than 50 mm, so as to prevent the tape from failing to meet the sealing strength of pipe wall and the service life of air duct. The advantage of thermal adhesive tape is that it depends on hot-melt bonding. As long as it is not heated, the bonding surface is solidified at room temperature, and it has strong bonding strength.
濟(jì)南通風(fēng)管道是一種用于循環(huán)空氣和降低有害氣體濃度的市政基礎(chǔ)設(shè)施。通風(fēng)管道和風(fēng)管生產(chǎn)安裝中使用的板材、型材等主要成品應(yīng)符合現(xiàn)行設(shè)計(jì)標(biāo)準(zhǔn)及相關(guān)產(chǎn)品的規(guī)定，并應(yīng)具有出廠檢驗(yàn)證書。材料進(jìn)場(chǎng)時(shí)，應(yīng)按現(xiàn)行標(biāo)準(zhǔn)驗(yàn)收。
Jinan ventilation pipeline is a kind of municipal infrastructure for circulating air and reducing the concentration of harmful gases. The main finished products such as plates and profiles used in the production and installation of ventilation pipes and ducts shall comply with the current national design standards and the provisions of relevant products, and shall have the factory inspection certificate. When entering the site, the materials shall be accepted according to the current national standards.
