Product Application:
1.Kuwedzera kune organic synthesis, chigadzirwa ichi chinoshandiswawo zvakanyanya se cellulose acetate film, cellulose triacetate pumping, petroleum dewaxing, solvents mukugadzirwa kweaerosols nemishonga inorwisa mabhakitiriya, mavitamini, steroidal compounds, pamwe chete nesimbi pamusoro pe lacquer kuchenesa uye kuderedza uye kuderedza mafuta. film remover.
2.Inoshandiswa muhupfu hwezviyo uye firiji yefriji yakaderera uye zvikwata zvemhepo.Inoshandiswa seyebetsero yekufuridza mugadziri wepolyether urethane furo uye seanofuridza ejenti ye extruded polysulfone foam.
3.Inoshandiswa se solvent, extractant uye mutagen.Inoshandiswa muplant genetic research.
4.Iine yakanaka solvency, inzvimbo yakaderera yekubikira inonyungudika ine huturu hushoma uye isingabatike pakati pezvinowanzo shandiswa maindasitiri zvinonyungudutsa, uye ine yakanaka solvency kune akawanda resins, parafini nemafuta.Inonyanya kushandiswa sependi stripper, petroleum dewaxing solvent, extractant of thermally unstable substances, extractant of lanolin kubva mumvere dzemakwai nemafuta anodyiwa kubva kukokonati, solvent ye cellulose triacetate film.Zvakare inoshandiswa zvakanyanya muacetate fiber, vinyl chloride fiber kugadzira, kugadzirisa uye zvinodzima moto, mafiriji, urotropine uye kumwe kugadzira.
5.Inoshandiswa muindasitiri yemagetsi.Inowanzoshandiswa sechinhu chekuchenesa kubvisa mafuta.
6.Inoshandiswa zvakanyanya semurazvo wemoto unogadzirisa solvent ine yakaderera kwazvo yekubikira.Pamusoro pekugezesa zvinonyungudutsa zveinjini dzendege, muchina chaiwo, nezvimwewo, inogona zvakare kushandiswa semushonga wekubvisa pendi, uye inogona zvakare kusanganiswa nezvimwe zvinonyungudutsa kuti zvishandiswe mukusiyana kwekugezwa kwemaindasitiri.
7.Inoshandiswawo se ethyl ester fiber solvent, mazino emunharaunda anesthetic, refrigerant uye moto wekudzimisa agent, nezvimwewo, inowanzoitika yekuparadzanisa chromatographic uye kubviswa kwekupatsanurwa kwezvinowanzogadziriswa.
8.Inoshandiswa se solvent mu resin uye indasitiri yepurasitiki.
Chigadzirwa Chekuchengetedza Notes:
1.Chengetedza munzvimbo inotonhorera, ine mhepo yekuchengetera mhepo.
2.Gara kure nemoto uye kupisa sosi.
3.Chengetedza pane tembiricha isingadariki 32°C uye hunyoro husingadariki 80%.
4.Chengetedza mudziyo wakavharwa.
5.Inofanira kuchengetwa zvakasiyana kubva kune alkali simbi uye makemikari anodyiwa, uye haafaniri kumbosanganiswa.
6.Kushongedzerwa nemhando dzakakodzera uye huwandu hwemidziyo yekudzima moto.
7.Nzvimbo yekuchengetera inofanira kunge yakashongedzerwa nekudonha kwechimbichimbi michina yekurapa uye yakakodzera pekugara zvinhu.
