Detergent AR-812 is a nonionic surfactant mainly composed of fatty alcohol polyoxyethylene ether, with an HLB value of 13 and a cloud point of 65~70°C (1% aqueous solution). It exhibits stable performance under normal use conditions. If abnormalities occur during use, they are usually related to operating conditions, water quality, or compatibility. Please check the following directions:
1. Unsatisfactory cleaning effect
Possible causes: Insufficient working solution concentration (recommended dosage is usually 0.5~3g\/L, depending on the degree of soiling), processing temperature exceeding the cloud point causing precipitation, working solution pH out of range, or processing time too short. It is recommended to check process parameters and adjust accordingly.
2. Stratification or turbidity
Possible causes: Improper compatibility with high-concentration electrolytes or strong acids\/alkalis, storage temperature below 5°C leading to increased viscosity or gelation (the product has a pour point <-10°C, but fluidity significantly decreases at low temperatures). If compounding is required, it is recommended to conduct a small-scale compatibility test first.
3. Excessive foam affecting production
Detergent AR-812 is a medium-foaming product. Under jet cleaning or high-speed stirring conditions, it may produce more foam. This can be resolved by appropriately reducing the dosage or adding a small amount of defoamer. You can also contact Guoli Chemical for low-foaming alternative products.
4. Product discoloration or odor
The normal product should be a colorless to light yellow transparent viscous liquid. If the color deepens significantly or an odor appears, it may be due to improper storage (e.g., prolonged exposure to high temperature or direct sunlight). It is recommended to check whether the storage conditions meet the requirements of 5~40°C, cool and dry.
In case of accidental contact or spillage, immediately take measures according to the following table and seek medical attention as necessary:
| Contact type | Emergency measures |
|---|---|
| Skin contact | Immediately remove contaminated clothing, rinse with soap and plenty of running water for at least 15 minutes; if irritation persists, seek medical attention |
| Eye contact | Eyelids lifted, rinse thoroughly with plenty of water or saline for at least 15 minutes; if persistent irritation or pain occurs, seek medical attention immediately |
| Inhalation | Move quickly to fresh air, keep airway clear; if breathing difficulty, give oxygen; if breathing stops, perform artificial respiration immediately and seek emergency medical attention |
| Ingestion | Rinse mouth with water, do not induce vomiting; immediately call a poison control center or seek medical attention, and present the product container or label |
| Small spill | Absorb with inert absorbent materials such as sand, vermiculite, collect in a sealed container, and dispose of as hazardous waste |
| Large spill | Build dikes or dig pits to contain, prevent entry into sewers or water bodies; transfer to dedicated containers using explosion-proof pumps for recovery and disposal |
