Sharp wind analysis of the use of pitch penetration instrument method and precautions
The use of pitch penetration meter:
The instrument is mainly used to measure the penetration of residues of viscous petroleum asphalt, viscous shale asphalt, and liquid petroleum asphalt, asphalt materials after distillation or emulsification.
The penetration of bitumen is below the specified time and temperature, and the depth of penetration of a standard needle with a certain weight is perpendicularly inserted into the sample.
The use of the asphalt penetration meter precautions are as follows:
1. When using the equipment, be sure to carefully read the technical specifications, familiar with the technical indicators, work performance, use methods, precautions, and strictly follow the instructions of the instrument manual to operate.
2. The personnel who use the equipment for the first time must perform operations under the guidance of skilled personnel. After skilled mastery, they can perform independent operations.
3. The equipment and equipment used during the experiment should be reasonably laid out, neatly arranged, easy to operate, observed, and recorded.
4, bent to the pipe should be installed at the bend.
5. When it is necessary to install it horizontally, it should be supported by a bracket made of fire-resistant clay or heat-resistant metal, and the outlet hole of the junction box should be downward to prevent water vapor from entering due to poor sealing.
6, heat resistance under pressure, its sealing surface must be sealed.
7. The equipment should not be operated in magnetic or electric fields. It must be shielded to prevent equipment damage or reduce measurement accuracy.
8, mechanical equipment, must be carried out before use, no-load operation to ensure no fault before loading. Lubricate before use and wipe clean after use.
Daily maintenance and maintenance of asphalt needle penetration meter:
1. Instruments and equipment can not be arbitrarily dismantled or dismantled. It is really necessary to implement new functions or to renovate and update them. It is necessary to implement the classification management authority and perform the examination and approval procedures later.
2. Always carry out maintenance and maintenance of the equipment, and store it in a dry and ventilated place. The equipment that has been in use for a long time is too long to be turned on and turned on to prevent the mold from damaging the components of the equipment.
3. Establish regular calibration of technical indicators for large-scale precision and valuable equipment, as well as a calibration system to maintain a proper technical indicator. Be sure to use your original records.
