解决玻镁复合板风管开裂的三大方式

1、风管板质量应达到《机制玻镁复合板风管》行业标准规定的技术指标:抗折荷载大于1200N,软化系数大于85%,游离氯离子含量小于等于3,无返卤现象。
1, the wind pipe plate quality should meet the industry standard technical indicators of "mechanism of glass magnesium composite board wind pipe: flexural load is greater than 1200n, softening coefficient greater than 85%, the content of free chloride ions is less than or equal to 3, no return to halogen phenomenon.
2、必须采用专用胶制作与安装风管。氧化镁加卤水不能作为胶粘剂,肯定要开裂。专用胶以氧化镁为主要原料,配以尼龙短纤维、耐水剂、保水剂,混合在一起配成粉剂(A组);在现场,将氯化镁配成波美度为24Be~26Be的卤液(B组)。A组、B组在现场混合调配成流体状即成专用胶。A组、B组调配的专用胶称之为双组份胶粘剂,浙江天仁风管有限公司已经研制成功单组份胶粘剂,在施工现场加水调和即可使用。这样解决了双组份胶粘剂配比随意大,不科学的缺点。

2, the use of special adhesive production and installation of the wind pipe. Magnesium Oxide plus brine can not be used as adhesive, it is sure to crack. Special glue to magnesium oxide as the main raw material with nylon short fiber, waterproof agent, water retaining agent, mixed together with powder (group A); at the scene, the magnesium chloride with wave Mido 24Be~26Be brine (group B). A group, B group in the field of blending into a fluid like a special adhesive. Deployment of group A and group B special glue bicomponent adhesive, Zhejiang Tianren wind tube Co., Ltd has been developed one component adhesive, at the construction site water harmonic can be used. This solution to the two groups of adhesive ratio arbitrarily large, unscientific shortcomings.
3、必须按《机制玻镁复合板制作与安装》标准图集施工。有许多风管生产单位不知道《机制玻镁复合板风管制作与安装》相关技术,或是不懂装懂欺骗用户,风管制作脏、乱、差,开裂严重。有的安装公司知道,却偷工减料,如单面上胶或胶不到位,将已失去流动性的胶继续使用等,造成风管严重开裂。等。
3, must be in accordance with the "" standard atlas construction and installation of production mechanism of glass magnesium composite plate. Have many of the wind pipe production units do not know the mechanism of glass magnesium composite board air duct fabrication and installation of related technology, or pretend to deceive the user, control wind as dirty, chaotic, and poor, serious cracks. Some installation company know, but Jerry, such as single side glue or adhesive is not in place, will have already lost mobility of glue to use, cause the severe cracking of the wind pipe. Etc..
