So, how can we correctly use the glue to firmly stick to the vacuum cleaner HDPE shell and the PVC tube?

 First of all, it is very important to choose the right glue. Because HDPE and PVC materials have different adhesion to glue, it is necessary to choose the glue that binds these two materials well. Usually, the special modified high strength structural glue ENIENT EG1012 is a suitable choice, because it has strong adhesion and corrosion resistance for HDPE and PVC, and can stick the HDPE and PVC materials well.

 Secondly, make sure that the adhesive surface is clean. Before using glue, make sure the HDPE housing and PVC tube surfaces are clean and free of grease or dust. The adhesive surface can be cleaned with detergent or alcohol cotton balls to ensure that the glue can make full contact with the surface and improve the effect and durability of the bonding.

 The adhesive surface then needs to be polished before applying the glue. Due to the characteristics of HDPE and PVC materials, the surface is relatively smooth and needs to be polished to improve the adhesion of the glue. Sand paper or grinding machine can be used to slightly polish the bonding surface to increase the roughness of the surface and contribute to the bonding effect of the glue.

 Next, apply the glue, and bond with it. For bonding, operate according to the instructions for the glue, usually apply a uniform layer of glue on the bonding surface, then contact the HDPE shell and the PVC tube and apply the appropriate pressure to ensure that the glue is fully filled between the bonding surfaces and can be firmly bonded.

 Finally, wait a certain period of time for the glue to dry completely. After the bonding is complete, be sure to wait for the glue to dry completely before using the vacuum cleaner, usually for more than 24 hours. This can ensure that the bonding effect of the glue can be durable and stable, will not appear loose or fall off.

 In short, the correct use of glue to firmly bond the vacuum cleaner HDPE shell and PVC tube needs to choose the right glue, keep the adhesive surface clean, properly polish, correctly smear the glue and bond, and wait for the glue to completely dry. Only in this way can we ensure that the vacuum cleaner shell and pipe can be firmly bonded, safer and more reliable.
