Raws li ib pab ntawm hluavtaws fiber ntau tig los txhim kho fiber ntau lub zog thiab ua kev ua haujlwm.

Xim & Txheej

Ntxiv rau dej - Ua cov txheej txheem ua yeeb yaj kiab los txhim kho cov txheej nplaum, yooj thiab dej tsis kam;

Siv hauv UV {-} Cov txheej txheem curable los kho cov viscosity thiab txhim khu kev txhawb nqa kev ua tau zoo.

Nplaum nplaum & las

Feem tivthaiv ntawm kev kub siab - Cov nplaum uas rhiab heev, muab cov khoom zoo sib xws;

Siv nyob rau hauv kub - yaj cov nplaum rau kev ntim khoom lag luam kom txhim kho melt kua thiab tsev ceev.

Roj av & Tsuas

Raws li cov roj oilfield?

Siv rau hauv cov ntxhia ua raws li dispersant los txhim kho ore flotation efficiency.

Kev Lag Luam Hluav Taws Xob

Siv nyob rau hauv kev tsim cov khoom nplaum hauv hluav taws xob thiab encapsulants rau semiconductor Cheebtsam;

Raws li kev ntxuav tus neeg sawv cev rau precision hauv hluav taws xob qhov chaw vim nws muaj peev xwm ua tau zoo muaj peev xwm.

Lwm Cov Ntawv Thov

Hauv cov tshuaj pleev ib ce kev lag luam zoo li cov tshuaj txau ntau yam los ntawm cov plaub hau txau thiab cov tsiaj qus rau zaj duab xis {{0} Txoj cai ua cov cuab yeej;

Raws li kev ua kom muaj kev ua kom rov qab kho cov txheej txheem hluav taws xob hluav taws xob;

Nruab nrab hauv cov synthic rau cov tshuaj thiab agnemicals.
