Product Use Description
1. Food industry
Citric acid is the largest organic acid produced by biochemical methods in the world. Citric acid and salts are one of the pillar products of the fermentation industry and are mainly used in the food industry, such as acidulants, solubilizers, buffers, antioxidants, Deodorant, flavor enhancer, gelling agent, toner, etc.
2. Metal cleaning
(1) Cleaning mechanism of citric acid
Citric acid has little corrosion to metals and is a safe cleaning agent. Since citric acid does not contain Cl-, it will not cause stress corrosion of equipment. It can complex Fe3+ and weaken the promotion effect of Fe3+ on corrosion.
(2)Use Citric acid to clean the pipeline
This is the latest cleaning technology for high-impurity hard water. It uses food-grade citric acid to soften stubborn scale, and then uses a microcomputer to control the water flow and pneumatics to generate water flow shocks, so that the old scale in the water pipe is peeled off and the water pipe is smooth and clean.
3) Compound surfactant to clean gas water heater
The chemical cleaning agent formulated with citric acid, AES and benzotriazole is used to clean the gas water heater that has been used for many years. The cleaning agent is injected into the inverted water heater, soaked for 1 hour, poured out the cleaning liquid, rinsed with clean water, and reused the water heater. Under the same flow rate, the outlet water temperature is increased by 5°C to 8°C.
(4) Cleaning the water dispenser
Dilute with edible citric acid (powder) with water, pour it into the heating liner of the water dispenser, and soak for about 20 minutes. Finally, rinse the liner repeatedly with clean water until it is clean, non-toxic and effective.
3. Fine chemical industry
Citric acid is a kind of fruit acid. Its main function is to speed up keratin renewal. It is often used in lotions, creams, shampoos, whitening products, anti-aging products, and acne products. In chemical technology, citric acid can be used as a reagent for chemical analysis, as an experimental reagent, chromatographic analysis reagent and biochemical reagent; as a complexing agent, masking agent; used to prepare buffer solutions.
4. Sterilization and coagulation process
The combined action of citric acid and 80°C temperature has a good effect of killing bacterial spores, and can effectively kill the bacterial spores polluted in the pipeline of the hemodialysis machine.
Citric acid anhydrous is packed in 25kg kraft paper bag, with inner plastic bag, 25MT per 20FCL
Jumbo bag in 1000kg can also be provided as to requirements.
