Nrog rau qhov nruab nrab koj tuaj yeem cais cov pigments hauv cov cim ruaj khov. … Nws yog qhov lom zem uas pom cov xim dab tsi uas cov chaw tsim khoom siv los ua ntau xim sib txawv. Cov tub ntxhais kawm yuav txaus siab rau qhov kev sim tshuaj lom neeg lom zem no.
Cov cim dab tsi zoo rau chromatography?
Qhov kev sim ua haujlwm zoo dua nrog cov ntawv lim lossis cov ntawv chromatography, tab sis cov no kim dua. Dub cwjmem raug pom zoo vim tias lawv feem ntau muaj ntau yam xim sib txawv hauv lawv tus cwj mem. Cov menyuam kawm ntawv yuav tsum raug txhawb kom sim cov cim ntawm cov xim sib txawv lossis xim zaub mov (xim zaub mov xim ua haujlwm zoo).
Vim li cas tus Sharpie tsis txav los ntawm daim ntawv chromatography?
Ib leeg yog tus number case tsis yog qhov sib xyaw . Yog tias tsuas muaj ib qho xwb, nws tsis tuaj yeem sib cais. Lwm qhov yog tias tus number case yog sib tov, thiab tag nrho cov khoom tseem ceeb sib npaug sib npaug rau cov kuab tshuaj thiab cov substrate, nyob rau hauv rooj plaub no lawv txhua tus tau mus rau tib tus nqi.
Cov kuab tshuaj dab tsi yog siv rau hauv cov cim ruaj khov?
Cov cim ruaj khov siv toluene thiab xylene hauv lawv cov kuab tshuaj uas muab cov cim lawv lub peev xwm tawm mus ntev. Cov cim ntxuav tau siv cov cawv xws li 1-propanol, 1-butanol, diacetone cawv thiab cresols hauv lawv cov kuab tshuaj.
Yuav ua li cas cov kuab tshuaj yuav tshem tawm cov cim cim cim kev tshawb fawb?
Yog koj pom koj tus kheej ntsib nrogzoo sib xws defacement-los yog koj tsuas yog tso tseg ib qho chaw ruaj khov rau ntawm ib qho nyuaj-koj tuaj yeem rub nws nrog cov tshuaj ntxuav tes, tab sis qhov ntawd tsis yog tib txoj kev daws teeb meem. Lwm cov kuab tshuaj muaj txiaj ntsig muaj xws li acetone-raws li tus ntsia thawv polish tshem tawm, rub dej cawv, thiab WD-40.

Nyob hauv chromatography yog dab tsi yog qhov chaw nyob ruaj khov?
Nyob rau hauv nyias txheej chromatography (TLC), cov theem nyob ruaj khov yog txheej nyias ntawm cov khoom, feem ntau yog silica-based, thiab theem mobile yog cov kua hauv cov sib tov ntawm kev txaus siab yog yaj. Nyias-txheej chromatography los nrog qhov zoo ntawm kev yees duab zoo, ua rau nws cov zis yooj yim rau digitize.
Puas muaj qhov chaw ruaj khov puas txhais tau tias tsis muaj zog nyob ruaj khov?
Thawj zaug nco ntsoov tias lub sijhawm kawg thib ob tsis suav tias yog lub ntsiab lus ntawm qhov muaj zog nyob ruaj khov, yog li, muaj zog ruaj khov tsis tas txhais tau tias tsis muaj zog nyob ruaj khov. Puas muaj zog nyob ruaj khov txhais tau tias tsis muaj zog nyob ruaj khov?
Puas yog kev ua haujlwm ruaj khov siv cov neeg laus?
SolidWorks siv NURBS-tab sis qhov ntawd tsis yog txheej txheem uas nws paub zoo tshaj plaws. SolidWorks yog tus qauv tsim software tshwj xeeb hauv parametric, keeb kwm-raws li qauv qauv, uas txawv ntawm qhov ncaj, dawb-daim qauv qauv uas tau ua NURBS ib lub npe tsev neeg hauv 3D manufacturing.
Dab tsi yog qhov txawv ntawm cov cim thiab cov cim cim?
