FAQ
San: Ndai DHP hpe hpa gaw grau ngang grin shangun ai kun?
A: Dai hta, grau nna acidic (sh) katsi ai shara ni hta, tinang hkrai byin pru wa ai hpe pat shingdang ya ai trace stabilizers (ga shadawn, BHT) ni lawm ai.
San: Stabilizer gaw THP ether byin pru wa ai hpe pat shingdang na kun?
A: N rai, dai stabilizer hpe sha kau ai (sh) tsa chyaru hpe makawp maga na matu lang ai standard acidic masa hta n shang lawm ai.
San: Ndai hpe tsi mawan galaw ai hta jai lang mai na kun?
A: Rai sai. Stabilizer gaw na a laksan application hte htuk manu ai hpe jep yu na matu hpaji jaw da ai, grau nna tara shang makau grup yin ni hta.
