Polymer joint impermeability meterProduct Introduction

meet the standard

Polymer joint impermeability meterCompliance with the mandatory national standard GBT26518-2023 General Specification for Building and Municipal Engineering Fan Water and the national standard "General Technical Specification for Building Fan Water Rolls" has added a requirement for the "impermeability of lap joints" of fan water rolls. This requirement will cover all lap processes such as hot melt, welding self-adhesive, adhesive, and tape. After the standard is officially implemented, "impermeability of lap joints" will become a mandatory item for the quality acceptance of fan water rolls. The importance of fan water: The construction of building fan water engineering is an important component of construction technology, and it is also a sub project construction to ensure that buildings and structures are not corroded and that internal spaces are not endangered. By the reasonable application of anti Shi materials, the occurrence of water immersion and leakage can be prevented, thereby ensuring the functional use of buildings and extending their service life.

Notes:

1. The equipment should not be operated in a magnetic or electric field, and shielding measures must be taken to prevent it from being used

Instrument and equipment damage or reduced measurement accuracy.

2. Mechanical instruments and equipment must undergo no-load operation before use to ensure they can be loaded and used. Lubricate before use and wipe clean after use.

3. Instruments and equipment are not allowed to be dismantled or disassembled for use at will. If there is a need to develop new functions or upgrade, they must be managed according to hierarchical authority, and approval procedures must be completed before implementation. 4. Regularly maintain and upkeep the equipment, and store it in a dry and ventilated place. If the equipment is not used for a long time, it should be powered on regularly to prevent moisture and mold from damaging its components.

5. Establish a regular verification and calibration system for technical indicators of large precision and valuable equipment, and maintain the necessary technical indicators. Follow the steps to operate the original recorder properly

(1) Before use, adjust the pressure gauge according to the test conditions of the specimen. The adjustment method is to set it to 0.5Mpa.

(2) When in use, loosen and remove the screws on the upper cover, and place the specimen to be tested on the circular bottom plate at the bottom; Then place the upper cover on the specimen and tighten it with screws; Unscrew the valve at the water inlet, then close the drain valve tightly. Slowly inject clean water from the water inlet until water emerges from the inlet hole in the middle of the permeable plate, and then start.

Main technical parameters
