Khoom Siv Khoom Siv Tshuaj:
Nws cov vapor thiab huab cua tuaj yeem tsim cov khoom tawg, uas tuaj yeem ua rau tawg thiab tawg thaum qhib hluav taws thiab kub kub. Cov nplaim taws kub hnyiab hauv huab cua yog qhov kaj thiab muaj cov pa luam yeeb dub muaj zog, kev sib xyaw ua tiav tsis tsim cov pa luam yeeb. Cov tshuaj tiv thaiv muaj zog nrog oxidizing tus neeg sawv cev. Kev kub ceev impa uact, ntws, agitation tuaj yeem tshwm sim los ntawm kev tsim hluav taws xob zoo li qub uas tshwm sim los ntawm combustion thiab tawg. Lub vapor hnyav dua li huab cua, thiab tuaj yeem kis mus rau qhov chaw deb ntawm qhov chaw qis, thiab yuav ntes hluav taws thaum nws ntsib qhov hluav taws kub.
Khoom siv:
1.Mainly siv raws li hnyav thiab ua roj extraction.
2.Siv raws li cov organic solvents thiab chromatographic tsom xam cov kuab tshuaj; siv los ua cov kuab tshuaj muaj txiaj ntsig zoo, tshuaj extractants, tshuaj lom neeg cov khoom siv ntxiv, thiab lwm yam.; tuaj yeem siv rau hauv cov khoom siv organic thiab cov khoom siv tshuaj lom neeg.
3.Used nyob rau hauv cov organic synthesis thiab tshuaj raw cov ntaub ntawv, xws li zus tau tej cov roj hmab hluavtaws, yas, polyamide monomer, hluavtaws detergents, tshuaj tua kab, thiab lwm yam., kuj yog ib tug zoo heev organic hnyav. Feem ntau siv los ua cov kuab tshuaj, kuj tseem siv los ua tus neeg sawv cev foaming rau foaming plastics, tshuaj, tsw extractant.
