Kufotokozera za khalidwe

Physicochemical katundu:
1.Zamadzimadzi zopanda mtundu komanso dour wokwiyitsa.
2.Kusungunuka kwamadzi, ethanol, benzene ndi ethyl ether immiscible, osasungunuka mu carbon disulphide.
Posungira:
1.Isungeni pamalo ozizira, opanda mpweya wabwino
2.Kutalikirana ndi kutentha pamwamba, zipsera, malawi otseguka ndi zina zoyatsira, osasuta. M'nyengo yozizira, sungani pamwamba pa 0 ℃ kuti mupewe kuzizira.
3.Sungani chidebe chotsekedwa mwamphamvu.chiyenera kukhala chosiyana ndi oxidant ndi alkali.
4.Gwiritsani ntchito zida zosaphulika [magetsi / mpweya / zowunikira].
5.Gwiritsani ntchito zida zosayambitsa moto.
6.Ground ndi chomangira chidebe ndi kulandira equipmen
Kugwiritsa ntchito
1. M'malo mwa glacial acetic acid, amagwiritsidwa ntchito popaka utoto ndi kumaliza ma pro-cesses a acrylic. dacron, nayiloni ndi Chemical fiber, ubweya. silika ndi nyama zina ulusi, thonje. nsalu. ulusi ndi mbewu zina CHIKWANGWANI, Waxprinting, ndi kusakaniza nsalu.
2. Kusintha kwa PH mtengo wa mitundu yonse ya pickling asidi, dyeingbath (kuphatikizapo kusamba kwamtundu), kukonza mtundu, kutsirizitsa utomoni etc.
3. Kupanga mitundu ina ya utoto, monga Benzidine Yellow G.
Ubwino
Ntchito ndi zotsatira zake ndizabwino kuposa ma asidi ena opaka utoto ndi glacial acetic acid.lt ilibe kuwonongeka kwa ulusi, mu dyeing bath pHvalue ndi stable.ilibe pinda la asidi, zinyalala ndi zotsatira za madzi olimba, kupititsa patsogolo kutengera utoto komanso kuyika katundu. Zazinthu zina, ndipo sizimakhudza kuwala kwachikuda kapena kufulumira kwamtundu wazinthu zopangidwa. Kuphatikiza apo, palibe fungo lamphamvu, losazizira m'nyengo yozizira, lotetezeka komanso losavuta kugwiritsa ntchito. Mfundo ya acetic acid endoscopy (AAC) :

1. Asidi acetic akhoza kuwononga disulfide chomangira glycoprotein mu chapamimba ntchofu wosanjikiza ndi depolymerize kapangidwe tetramer wa glycoprotein, chifukwa ntchentche woonda, amene mosavuta kutsukidwa ndipo amathandizira kuyeretsa chapamimba mucosal pamwamba.

2. Acetic acid imatha kulowa mu cytoplasm kudzera mu cell membrane, ndikupanga pH mtengo mu cytoplasm kuchoka ku 7.0-7.4 mpaka 6.5, cell keratin polymerizes kukhala mitolo, maselo amakhala okulirapo, kufalikira kwa kuwala kumachepa, kapangidwe ka mapuloteni a epithelial. maselo amasinthidwa, ndipo katundu wa maselo a epithelial amasinthidwa mwachisawawa. Zimapangitsa mapangidwe apakati a chromatin ndi intracellular keratin mu kusintha kwaposachedwa kwa cytoplasm, kuwonetsa mawonekedwe a morphological a mucosal pamwamba, kenako ndikuwunikira ma cell a epithelial okhala ndi kuwala koyera, kutulutsa chodabwitsa. Mwachitsanzo, permeability wa maselo epithelial kumawonjezeka. Acetic acid imalowa pang'onopang'ono mu nyukiliyasi imathanso kutulutsa DNA ya superhelix ndikulimbitsa kuyera. Acetic acid itasinthidwa pang'onopang'ono ndi cytoplasm, zomwe zili pamwambazi zidazimiririka.

3. Acetic acid imatha kufika ku interstitium kudzera mucosa, zomwe zimapangitsa kuti capillary iwonongeke. Choncho, acetic acid kupopera mbewu mankhwalawa, mucosa pang`onopang`ono kusanduka wofiira pambuyo mphindi 2-3 woyera. Kupopera kwa acetic acid kumawonjezera pamwamba pa maselo a epithelial a zinthu zosawonetsera, zimatha kuphimba mitsempha ya mitsempha pansi pa epithelium.

4. Kutsegula kwa glands kapena crypts ndi imodzi mwa njira zolowera acetic acid, zomwe zimawonjezera malo a maselo omwe amawonekera ku acetic acid, ndipo amachititsa kuti mucosa ikhale yokhuthala ndi yoyera yonse. Mawonekedwe a concave akuwonetsedwa bwino, ndipo mawonekedwe otsegulira a ngalande ya microglandular amatha kuwoneka bwino.

5. Kutalika kwa mucosal whitening zimasiyanasiyana malinga ndi mlingo wa zotupa mucosal ndi chotupa kusiyana. Mucosa wamba imakhala ndi nthawi yoyera yotalikirapo (mphindi 1-2), pomwe kusiyanitsa kapena submucosal carcinoma imakhala ndi nthawi yoyera yayifupi (masekondi 3-10), ndipo mzere wapakati umapangidwa pakati pa minofu ya khansa ndi minofu yozungulira ya mucosal, yomwe ikuwonetsa kukula kwa minofu ya khansa. Komanso, zingathandize kusiyanitsa ndi kuzindikira zotupa ndi microvascular atypia ndi microstructure osadziwika pamwamba pansi wamba magnification endoscopy, komanso kungathandize kwambiri kudziwa mlingo wa chapamimba mucosa ndi matumbo metaplasia.
