Improved epoxy construction method for floors of wafer tubes of wafer board in clean room

Abstract

The invention provides an improved epoxy construction method for the floors of the wafer tubes of a wafer board in a clean room. The method does not require high proficiency of workers. Fewer workersare arranged to attach cardboards and make marks at lantern ring positioning pins before installation and fixation of lantern rings. The protection of wafer tubes is completed during the installationand fixation of the lantern rings, namely, middle construction can be carried out. Thus, pipeline operation is achieved, and manpower is saved. The two steps of lantern ring installation and fixationand tube hole protection in the traditional construction method are combined into one step of installation and fixation of the lantern rings containing cardboards. The new construction method improvesthe work efficiency, shortens the construction period, saves manpower, reduces cost, avoids the potential safety hazards in repeated construction, and achieves pipeline operation. Moreover, the cardboards are convenient to remove, the wafer tubes are convenient to clean, and no secondary pollution will be caused. The method has great advantages in the epoxy construction of the floors of the wafertubes of a wafer board in a large clean room. Moreover, the cardboards can be processed in advance, are light and easy to store, can be reused, are cost-saving, are easy to recycle, and protect the environment.

Description

technical field [0001] The invention relates to an epoxy construction method, in particular to an improved epoxy construction method for a waffle board waffle tube floor in a clean room. Background technique [0002] Epoxy construction of the floor of the traditional waffle board waffle tube. After the collar is installed and fixed, the protection construction process of the waffle tube is carried out. Tape and film are used to protect the opening of the waffle tube. At the same time, it must be attached completely to avoid intermediate coating. Epoxy mid-coat flows into the barrel when done. [0003] The original process is specifically: [0004] (1), plain sanding and vacuuming: [0005] 1) When polishing and cleaning the plain ground, it is necessary to use a small disc grinder to polish the ground and vacuum it. This should be done when the protective cover of the original civil construction waffle cylinder is not removed, so as to ensure that the inside of the waffle ...

[0024] 2) The thickness of the epoxy should be uniform, not thick in some places and thin in some places, which will affect the appearance and flatness

[0026] This construction method requires a large number of skilled workers to squat and bend twice for installation and attachment (the first time the collar is installed and fixed, and the second time the protective film of the waffle hole is attached), the work efficiency is low, and the diameter of the waffle hole is There are certain safety hazards in the 410mm construction, and the film is easily damaged during the construction process, and it is easy to fall off after a long time, making it difficult to protect the finished product

Finally, the film needs to be removed after the epoxy top coating is completed, and the film cannot be recycled again, resulting in waste of materials
