Daim ntawv thov
1. Es tsis txhob glacial acetic acid, nws yog siv nyob rau hauv dyeing thiab finishing pro-cesses ntawm acrylic. dacron, nylon thiab lwm yam tshuaj fiber ntau, ntaub plaub. silk thiab lwm yam tsiaj fiber, paj rwb. linen. xov paj thiab lwm yam nroj tsuag fiber ntau, Waxprinting, thiab muab ntaub.
2. Kev hloov kho ntawm PH tus nqi ntawm txhua yam acid pickling, dyeingbath (xws li da dej xim), xim kho, resin xov thiab lwm yam.
3. Ua tau qee yam dyestuff, xws li Benzidine Yellow G.
Qhov zoo
Kev ua haujlwm thiab cov nyhuv zoo dua li lwm cov dyeing acid andglacial acetic acid.lt tsis muaj kev puas tsuaj rau cov fiber ntau, hauv dyeing da dej pHvalue yog ruaj khov.it tsis muaj kua qaub quav, sediment thiab cov teebmeem ntawm cov dej tawv, txhim kho cov xim zoo nkauj thiab qib-dyeing khoom. ntawm somedyestuff, thiab tsis muaj teebmeem rau cov xim xim lossis xim ceev ntawm cov khoom lag luam.Ntxiv rau, tsis muaj ntxhiab tsw ntxhiab, tsis khov rau lub caij ntuj no, muaj kev nyab xeeb thiab siv tau yooj yim.Principle of acetic acid endoscopy (AAC):

1. Acetic acid tuaj yeem rhuav tshem cov disulfide daim ntawv cog lus ntawm glycoprotein hauv cov kab mob hauv plab thiab depolymerize cov qauv tetramer ntawm glycoprotein, uas ua rau cov hnoos qeev nyias nyias, uas yooj yim ntxuav tawm thiab ua lub luag haujlwm hauv kev ntxuav lub plab mucosal.

2. Acetic acid tuaj yeem nkag mus rau cytoplasm los ntawm cov cell membrane, ua rau pH tus nqi hauv cytoplasm poob los ntawm 7.0-7.4 mus rau 6.5, cell keratin polymerizes rau hauv cov pob, cov hlwb ua tuab, lub teeb transmittivity txo qis, cov protein architecture ntawm epithelial. cov hlwb raug hloov, thiab cov khoom ntawm cov hlwb epithelial raug xaiv hloov. Nws ua rau cov qauv spatial ntawm intracellular chromatin thiab intracellular keratin nyob rau hauv cytoplasm hloov pauv hloov pauv, qhia txog cov qauv morphological ntawm mucosal nto, thiab tom qab ntawd qhia txog cov cell columnar epithelial nyob rau hauv lub teeb dawb irradiation, ua whiteness tshwm sim. Piv txwv li, lub permeability ntawm epithelial hlwb nce. Cov acetic acid ib nrab nkag mus rau hauv lub nucleus tuaj yeem tshem tawm cov superhelix DNA thiab ntxiv dag zog rau cov nyhuv whiteness. Thaum acetic acid maj mam neutralized los ntawm cytoplasm, cov nyhuv saum toj no ploj mus.

3. Acetic acid tuaj yeem ncav cuag lub interstitium los ntawm mucosa, ua rau capillary congestion. Yog li ntawd, tom qab acetic acid txau, cov mucosa yuav maj mam tig liab tom qab 2-3 feeb dawb. Cov tshuaj acetic acid tau nce saum npoo ntawm cov hlwb ntawm cov khoom siv tsis pom kev, tuaj yeem npog lub vascular network hauv qab epithelium.

4. Qhov qhib ntawm cov qog los yog crypts yog ib txoj hauv kev rau acetic acid infiltration, uas ua rau thaj tsam ntawm cov hlwb raug acetic acid, thiab ua rau cov mucosa thickened thiab whitened zuag qhia tag nrho. Cov duab concave tau pom meej meej, thiab cov duab qhib ntawm microglandular kwj dej tuaj yeem pom tau meej.

5. Lub sij hawm ntawm mucosal whitening nws txawv raws li qib ntawm mucosal lesions thiab qog sib txawv. Cov mucosa ib txwm muaj lub sijhawm dawb ntev (1-2 feeb), qhov sib txawv lossis submucosal carcinoma muaj lub sijhawm dawb luv (3-10 vib nas this), thiab cov kab demarcation yog tsim los ntawm cov ntaub so ntswg cancer thiab cov ntaub so ntswg ib puag ncig, delineating cov thaj tsam ntawm cov qog nqaij hlav cancer. Tsis tas li ntawd, nws tuaj yeem pab kom paub qhov txawv thiab kuaj pom qhov txhab nrog microvascular atypia thiab qhov tsis meej ntawm qhov chaw microstructure nyob rau hauv qhov kev nthuav dav zoo tib yam endoscopy, thiab tseem tuaj yeem txhim kho qhov kev kuaj pom ntawm gastric mucosa thiab plab hnyuv metaplasia.
