Water and heat are only part of the equation. To achieve deep cleaning, you need the right PET washing chemicals. In a professional hot wash cycle, two main components are used to transform dirty plastic into high-value raw material.

  1. Soda ya Caustic (Sodium Hydroxide – NaOH): Kwa kawaida huongezwa kwa mkusanyiko wa 1% hadi 2%. Kazi yake kuu ni kuondoa mafuta na kutengeneza tena madoa yanayotumika kwa lebo. Inafanya kazi kwa ufanisi “kuondoa” uchafu kutoka kwenye uso wa PET.
  2. Detergenti/Msafishaji Maalum: Wakati soda ya caustic inafanya kazi kubwa, surfactant husaidia kusimamisha uchafu na mafuta yaliyonyoshwa kwenye maji, kuzuia kurudi tena kwenye vipande.

Proper dosing of these cleaning additives is critical. Too little, and the flakes remain oily; too much, and you increase your wastewater treatment costs.
