Product Performance

DEMARKAL DT can slowly in'€☆crease the pH value of★"≈ the chrome tanning solution, and give u<'₽♥niform alkali extraction without prod≠≠☆ucing a sharp change in the pH value of the♠€ ✔ chrome tanning solution✘ βε.
DEMARKAL DT can make the distribution of chromiλ★um in the leather more uniform, blue cσ olor light uniform, grain surface compact and fin•≠$e.

Application Reference

DEMARKAL DT after the chrome taσ±¥₩nning agent is completely penetrated, it is a&γdded in 2 times with an in♦•terval of 30 minutes. The dosage is determined e÷§xperimentally at 0.4-0.6 (b↔γased on gray bare tare ®∞weight) depending on the pH of the picklin§α∞g and the thickness of the b≤£✘€are skin.
Rotate for at least 8 hours after a↓✘ddition of DEMARKAL DT, with an end temperaturγσe of not less than 38≈™<•°C. Higher temperature is conducive t↕™↕ o the rapid increase of PH ®↓✔<value, so it is recommended to reasonabl•↓y control the temperature at the initial stageγ‍ of alkali extraction and heating acco≥λΩ&rding to the situation.
