Hydrophilic precipitated silica
Precipitated silica yog muab faib ua ke ua ib txwm muaj nag los silica thiab tshwj xeeb precipated silica. Lub qub dhau los yog hais txog silica tsim nrog sulfuric acid, thaum lub tom qab cov txheej txheem tshwj xeeb, cov txheej txheem crystallity, theem nrab crystallization txoj kev lossis tus txheej txheem rov qab. -
