How to use
- Cleaning is typically performed using ultrasonic or spray methods, though immersion and manual brushing may also be employed.
- Cleaning duration ranges from 5 to 30 minutes, with specific timing adjusted according to product requirements.
- Optimal temperature for cleaning and rinsing solutions is maintained between 45–55°C, with duration adjusted per product specifications.
- After a period of cleaning, residue buildup in the cleaning solution reduces cleaning efficacy and compromises part cleanliness. Based on actual usage, regularly replenish or replace the cleaning solution in the tank (determined by the number of steel screens being cleaned).
- After a period of rinsing, the concentration of cleaning agent in the rinse solution increases, leading to reduced cleanliness of the rinsed parts. Based on practical experience, it is recommended to replace the rinse solution every 2 to 4 hours (depending on the number of steel screens being cleaned).
Precautions
- This product is a specialized cleaning agent that must be prepared with deionized water to form the working solution. The cleaning solution must not be mixed with other cleaning agents.
- After opening the product and using a portion, the cap must be tightly secured to prevent the cleaning agent from evaporating.
- Do not store used and unused cleaning agents in the same container. If any cleaning agent remains in the container after opening, do not leave it exposed to air; tighten the cap immediately.
- Keep containers holding the cleaning agent clean to prevent contamination from dirt or other substances, which may affect the cleaning agent's quality.
- Separation or cloudiness after prolonged storage is normal. Shake well before use for optimal results.
- Ensure no cleaning agent residue remains on glass surfaces after rinsing.
- After extended cleaning periods, adding the recommended defoamer will enhance foam suppression.
