1. Hydroquinone feem ntau yog siv los ua tus tsim duab thaij duab. Hydroquinone thiab nws cov alkylates tau dav siv los ua polymer inhibitors hauv cov txheej txheem ntawm monomer cia thiab kev thauj mus los. Qhov feem ntau concentration yog txog 200ppm.
2. Nws tuaj yeem siv los ua roj hmab thiab roj av antioxidant, thiab lwm yam.
3. Hauv kev kho mob, hydroquinone yog ntxiv rau cov dej kub thiab txias
dej ntawm lub kaw hluav taws xob cua sov thiab cua txias, uas tuaj yeem cuam tshuam qhov corrosion ntawm cov hlau ntawm dej sab. Hydroquinone nrog rau lub qhov cub dej deaerating tus neeg saib xyuas, hauv boiler dej preheating deaeration yuav muab ntxiv rau hydroquinone, thiaj li yuav tshem tawm cov residual yaj oxygen.
4. Nws tuaj yeem siv los tsim cov tshuaj anthraquinone, azo dyes, tshuaj raw khoom.
5. Nws tuaj yeem siv los ua cov tshuaj detergent corrosion inhibitor, stabilizer thiab antioxidant, tab sis kuj siv rau hauv cov tshuaj pleev ib ce plaub hau.
6.Photometric kev txiav txim siab ntawm phosphorus, magnesium, niobium, tooj liab, silicon thiab arsenic. Polarographic thiab volumetric txiav txim siab ntawm iridium. Reducers rau heteropoly acids, reducers rau tooj liab thiab kub.
