Patch wear-resistant ceramic pipes are mostly used in heavy wear industries such as power plants, steel plants, cement plants, etc., for conveying powders, liquids, gases, etc. There are strict steps and requirements for pasting ceramic sheets on the lining of patch ceramic pipes. Let's talk about the specific methods and precautions of ceramic patches.
Pretreatment work: Before pasting the ceramic sheets, the pipes need to be moved to a suitable location for construction, and the parts to be pasted should be carefully polished. Through polishing, rust, oxide layers and other impurities must be removed until a clean iron surface is exposed, laying a good foundation for subsequent pasting work.
Clean the polished area: After polishing, use a diluent (such as alcohol, acetone, etc.) to thoroughly clean the polished area to ensure that there are no dust, oil, or other impurities on the surface to ensure that the adhesive can fully adhere to the metal and ceramic surfaces.
Prepare the adhesive: Prepare the adhesive at room temperature according to the specified ratio (usually 2:1 between the main adhesive and the curing agent). During the preparation process, ensure the adhesive is mixed evenly and free of granular substances. The prepared adhesive should be used within the specified time to avoid premature curing of the adhesive and waste.
Evenly apply the adhesive: During the application of the adhesive, ensure that the application is comprehensive and even. Not only should the polished metal parts be covered, but also the front and four sides of the ceramic sheet should be coated with adhesive. When applying, be careful to avoid the phenomenon of lack of glue or excessive glue.
Paste the ceramic sheet: After the application of the adhesive, the ceramic sheet should be pasted immediately. During the pasting process, use a blade to cut the adhesive paper along the gap of the ceramic sheet to ensure that the adhesive can fully penetrate. Then, use a wooden hammer or other tools to compact the ceramic sheet so that the excess adhesive flows out of the gap. At the same time, ensure that the gaps between the ceramic sheets are also filled with adhesive and evenly applied.
Curing and operation: After the pasting is completed, the pipeline is cured. The curing time is usually 24 to 48 hours, depending on the characteristics of the adhesive and the ambient temperature. After the curing is completed, the pipeline can be put into normal operation.
Throughout the process, it is necessary to strictly follow the steps and requirements to ensure the quality and performance of the wear-resistant ceramic patch pipe. At the same time, it is also necessary to pay attention to the safety and sanitation of the construction environment to avoid adverse effects on construction personnel and the surrounding environment.
