Daim ntawv thov

1. Kev tsim cov polymers
Nws yog dav siv los ua polymerization spinning hnyav rau polyacrylonitrile.
Tsis tas li ntawd, nws kuj yog siv los ua cov kuab tshuaj rau cov khoom siv urethane, hnyav rau photosensitive polymer synthesis, thiab ntxuav cov khoom siv polymerization.
2. Extraction hnyav
Nws pom zoo solubility zoo rau cov tshuaj tsw qab, unsaturated hydrocarbons thiab sulfur compounds.Txawm li cas los xij, kev solubility ntawm cov khoom zoo li paraffin yog qhov tsawg heev, thiab cov txheej txheem BTX extraction (IFP) tau tsim los siv cov yam ntxwv no.
3. Cov kuab tshuaj thiab cov khoom siv raw rau tshuaj tua kab
Cov tshuaj tua kab uas nyuaj rau yaj hauv lwm cov kuab tshuaj yog yooj yim yaj hauv DMSO, thiab los ntawm lub zog nkag ntawm DMSO, cov tshuaj tua kab yuav nkag mus rau hauv tag nrho cov ntoo, ua rau cov tshuaj tua kab ntau ntxiv.
DMSO nws tus kheej yog cov khoom siv raw rau cov tshuaj tiv thaiv thiab siv los tsim cov tshuaj tua kab.
4. Solvents rau dyes thiab pigments
Siv DMSO ua cov kuab tshuaj rau dyes thiab pigments tuaj yeem txhim kho kev ruaj ntseg.Tus nqi dyeing ntawm cov organic pigments yuav raug txhim kho los ntawm kev sib ntxiv ntawm DMSO.
Tsis tas li ntawd, nrog rau qhov muag mus rau qhov tsis muaj tshuaj lom, ntau thiab ntau cov khoom tau raug hloov mus rau DMSO ua cov kuab tshuaj.
5. stripper
DMSO tuaj yeem siv los ua tus stripper, thiab cov nyhuv tuaj yeem txhim kho yog tias DMSO ntxiv rau cov xim stripper.DMSO muaj txiaj ntsig tshwj xeeb hauv kev tshem tawm cov txheej txheem epoxy.
6. Cov tshuaj tiv thaiv xeb
Siv los ua ib qho hnyav rau qee yam xeb inhibitor.
Tsis tas li ntawd, DMSO nws tus kheej tuaj yeem cuam tshuam kev loj hlob ntawm cov kab mob.
7. Cov tshuaj tiv thaiv hnyav rau cov tshuaj synthesis
Ntxiv nrog rau ntau yam tshuaj tua kab mob xws li cephems, nws yog dav siv los ua cov tshuaj tiv thaiv nruab nrab thiab purification hnyav rau ntau yam tshuaj.
8. Kev ntxuav cov tshuab precision thiab cov khoom siv hluav taws xob
Qhov tsawg toxicity ntawm DMSO yog ib qho kev txhawj xeeb tshwj xeeb.Tsis tas li ntawd, muab cov khoom no tso rau hauv DMSO, xws li khov thiab tom qab ntawd tawg, yuav txhim kho cov nyhuv tu.
9. Impregnation hauv polymer
Thaum ntxiv ib yam khoom uas tsis ruaj tsis khov thermal zog rau lub polymer, lub hom phiaj cov khoom yog yaj nyob rau hauv DMSO, thiab cov polymer muab tso rau hauv cov kua yaj thiab ces qhuav.Txoj kev no tab tom kawm.
10. Muab faib rau cov nroj tsuag
DMSO kuj tseem siv tau rau cov nroj tsuag.
Kev loj hlob ntawm cov nroj tsuag tuaj yeem txhawb nqa los ntawm kev faib cov dej noo uas muaj DMSO hauv cov nroj tsuag.
11. Kev txhim kho ntawm cov khoom siv polymer
DMSO tuaj yeem muab ntxiv rau qee cov polymers los txhim kho cov khoom.
12. Kev ua yeeb yaj kiab
Nws yog siv nyob rau hauv kev tsim ntawm ntau yam sib cais daim nyias nyias xws li hollow fibers rau lub raum dag, sab nraud pom daim nyias nyias, rov qab osmosis daim nyias nyias, thiab ion pauv membranes.
