Daim Ntawv Thov Khoom

NHDyog ib hom tshuaj tshiab uas muaj zog heev rau de-sulfurizing thiab de-carbonating solvent nrog purity siab, zoo heev chemistry & heat stability rau cov media uas muaj acidity siab, alkality thiab kub. Nws yog qhov tsim nyog rau kev ntxuav cov roj anthraco-synthetic. Nws tuaj yeem ua kom cov hydrogen vulcanized tawm ntawm cov roj acid sib xyaw ntawm cov roj av, cov roj av hauv cov roj av, cov roj thee hauv cov Hoobkas lossis cov nroog thiab cov roj av liquefied. Hauv particular, nws tuaj yeem ua kom cov organic sulfur de-sulfur zoo.
