Microscope Instrument Micro Observation Technology hauv Cotton Textile Industry
Kev txheeb xyuas cov qauv fiber ntau:
(1) X-ray thiab Electron Diffraction - Qhov sib txawv ntawm cov duab diffraction tau los ntawm irradiating fibers sib txawv nrog X-rays tuaj yeem siv los txheeb xyuas ntau hom fibers
(2) Infrared spectroscopy (Infre liab) - siv cov yam ntxwv thiab tshuaj pawg ntawm ntau fibers los txheeb xyuas cov fibers hauv infrared spectroscopy
(3) Ultraviolet, Fluorescence - Fluorescent X-rays tawm los ntawm cov khoom sib txawv muaj qhov sib txawv wavelengths, thiab tom qab ntawd tshuaj xyuas siv spectroscopy
(4) Nuclear magnetic resonance (NMR) - yog hais txog kev hloov pauv ntawm resonance tshwm sim ntawm lub zog sib nqus ntawm atomic nuclei uas tsis yog xoom spin lossis angular momentum nyob rau hauv ib qho chaw tsis tu ncua sab nraud magnetic teb, qhov twg lub sij hawm nuclear sib nqus tau quantized nyob rau hauv ntau yam lus qhia. Nyob rau hauv qhov kev txiav txim ntawm electromagnetic nthwv dej ntawm lwm zaus, lub resonance hloov phenomenon tshwm sim nyob nruab nrab ntawm lub magnetic zog theem ntawm atomic nuclei, uas yuav soj ntsuam qhov kev txiav txim ntawm atomic pawg los yog atomic kev npaj nyob rau hauv molecules thiab cov khoom ntawm tshuaj bonds.
(5) Lwm txoj hauv kev suav nrog Raman spectroscopy, kev tshuaj xyuas saum npoo, thiab ntau yam kev siv hluav taws xob microscopy.
Cov qauv fiber ntau tuaj yeem raug suav los ntawm nws lub cev thiab tshuaj lom neeg, siv cov qauv hauv qab no:
(a) Thermal analysis method, dynamic and fracture mechanics method: Nws yog ib lub tshuab uas ntsuas lub cev ntawm cov khoom thiab nws qhov kub thiab txias kev sib raug zoo nyob rau hauv tus txheej txheem tswj kub. Hauv kev lag luam ntawm cov tshuaj fiber ntau, muaj ntau txoj hauv kev siv ntau yam, xws li thermogravimetry (TG) thiab dim pa tsom xam (EGA) rau kev ntsuas kev hloov pauv, kev ntsuas qhov sib txawv thermal (DTA) rau kev ntsuas kub hloov, thiab qhov sib txawv scanning calorimetry (DSC) rau kev ntsuam xyuas cov ntsiab lus kub hloov, Muaj cov txheej txheem thermal expansion rau kev ntsuas qhov hloov pauv, thermal mechanical analysis (TMA) thiab dynamic mechanical analysis (DTMA) rau kev ntsuas cov khoom siv hluav taws xob, thiab cov txheej txheem thermal optical rau kev kuaj cov khoom kho qhov muag.
(b) Mass spectrometry: Ib txoj hauv kev tsom xam uas tus qauv yog ionized los ua ib pawg spectrometry.
Nws tuaj yeem ntsuas qhov hnyav molecular thiab hom qauv ntawm cov organic teeb meem, nrog rau txheeb xyuas cov organic teeb meem thiab nws cov qauv. Spectral kab nrog sib txawv siv tau los ntawm ion rhiab daim hlau, hu ua huab hwm coj spectra. Raws li qhov loj spectrum, qhov hnyav molecular thiab hom qauv ntawm cov khoom tuaj yeem txiav txim siab.
