What kind of chemical do you use to wash PET bottles and PET flakes?
We use three kinds of detergent to wash the flakes. NaOH, Na3PO4 and T-31. The T-31 detergent is designed by BORETECH from the year 2000 with a chemical works factory. The BORETECH’s engineer went to the chemical works factory and brings many dirty bottles for explaining what contamination should be removed. Then the chemical works factory designed formula of the T-31 detergent according to BORETECH’s requirement. Even BORETECH doesn’t know the formula of the detergent. The BORETECH’s operation engineer will help the buyer to optimize the chemical mixing formula.
