luv luv piav qhia:

Cov tshuaj lom neeg feem ntau yog siv los tsim ntau tshaj 90 hom kua qaub, ncaj thiab reactive dyes, xws li acid fuchsin 6B, kua qaub caws pliav G, kua qaub dub 10B, ncaj dub, reactive ci liab K-2BP, reactive violet KMY 3R, reactive soluble xiav KMY R, thiab lwm yam. Cov dyes no yog siv rau dyeing wool thiab paj rwb fabrics.Nws kuj tuaj yeem siv rau hauv kev tsim tshuaj.
Nws yog xim av xim liab hauv kev sib cuam tshuam nrog ferric chloride tov.Cov kua qaub ntsev muaj xim liab fluorescence, uas hloov liab-liab ntshav thaum alkali ntxiv.H acid cov khoom feem ntau yog muab tshuaj txhuam los yog hmoov.

Kev piav qhia

Lub disodium ntsev thiab caustic soda concentrated tov ntawm Koch acid (1-naphthylamine-3 mine6 thiab 8-trisulfonic acid) tau rhuab thiab melted nyob rau hauv lub siab kub ntawm txog 180-190 ℃, ces cov melts yog yaj nyob rau hauv dej thiab ces acidified thiab nag xob nag cua.Me ntsis soluble hauv dej txias, soluble hauv alkaline daws xws li dej qab zib tshauv thiab caustic soda.

Nrog ferric chloride tov yog xim av liab.Cov kua qaub ntsev muaj xim liab fluorescence, thiab dhau los ua ntshav liab tom qab ntxiv alkali.H acid cov khoom feem ntau yog muab tshuaj txhuam los yog hmoov.
