Cov Nta Tseem Ceeb
So
Cov nruab nrab yuav tsum yog solible nyob rau hauv cov kuab tshuaj, kom lawv tuaj yeem tau yooj yim thiab muaj kev cuam tshuam nrog lwm cov tshuaj ua kom tuag.
Ruaj khov
Thaum cov cub cub cub yog ruaj khov nyob rau hauv cov kev tshwm sim hauv cov zas tshuaj synthesis, kom muaj kev ntxhov siab lossis hloov pauv mus rau hauv dyes.
Kev coj dawb huv
Cov khoom nruab nrab ntawm cov ntshiab yuav tsum ua kom dawb huv, raws li impurities tuaj yeem cuam tshuam qhov zoo thiab cov khoom ntawm cov dyes ua. Cov Purity Fli Flary intermediates kom cov dyes tsim tawm yog qhov ua tau zoo thiab muaj cov khoom ntiag tug.
Hom zas xim muaj
Cov tshuaj uas muaj ntxhiab tsw amines
Cov khoom noj uas muaj ntxhiab tsw yog cov organic sib xyaw uas muaj pawg amine (-nh2) txuas nrog lub nplhaib uas muaj ntxhiab. Lawv tau siv los ua cov nruab nrab rau cov synthesis ntawm Azo Dyes, uas yog feem ntau siv dyes hauv kev lag luam textile.
Nitro tebchaw
Nitro cov tebchaw yog cov organic sib txuas uas muaj ib pab pawg nitro (-no2) txuas nrog lub nplhaib uas muaj ntxhiab. Lawv kuj tau siv nyob rau hauv kev tsim cov khoom ntawm lwm hom dyes, xws li cov kua qaub kua qaub thiab cov dyes disperse.
Heterocyclic Tebchaw
Heterocyclics yog cov organic sib txuas uas muaj ib lossis ntau dua heteroatoms, xws li nitrogen, oxygen, lossis leej faj, hauv lub nplhaib qauv. Lawv tau siv los ua cov nruab nrab rau cov hluavtaws ntawm ntau hom dyes, xws li vat dyes, leej faj dyes, thiab reasive dyes.
Cov Ntawv Thov
Zas
2, {4-} Dichhlorobenzaldehyde lub ntsiab lus liab xiav zas xim thiab tua cov diluted hexaconazole.
Agnchemicals
2, {{4- dichhlorobenzaldehyde yog cov khoom siv hauv kev tsim cov tshuaj tua kab mob thiab cog cov neeg tswj hwm kev loj hlob. Nws tau siv hauv qee cov qauv rau cov kev tswj kev tswj hwm hauv kev ua liaj ua teb.
Cov tshuaj tsw qab thiab cov ntxhiab
Vim nws cov khoom muaj ntxhiab tsw qab, nws qee zaum hauv cov hluavtaws ntawm cov naj hoom thiab cov tshuaj tsw qab.
Ntim
Rau cov me me kuaj kom muaj nuj nqis<1 kilograms, inside we use double resealable zip bags and outside with aluminium Foil Bags.
Rau nruab nrab quanity 1-25 kilograms, sab hauv peb siv ob chav uas tau muab ob npaug rau cov hnab ntawv ci, tom qab ntawd ntim cov nruas lossis cov nruas me me rau kev xa khoom.
For larger quanity >25 Kilo, sab hauv peb siv ob chav uas ci thiab sab nraud nrog aluminium ntawv foob ob lub hnab tsiaj rau 25kgs nyob rau hauv cov nruas rau kev xa khoom.
Chaw ntim khoom
Khaws cia rau hauv qhov txias thiab nruj nreem kaw cia tank. Khaws tseg ntawm qhov hluav taws kub, qhov cua sov, kom tsis txhob muaj lub teeb muaj zog. Khaws lub thawv ntim kom ruaj nroos ntim.Koj cais tawm ntawm oxidant, acids thiab cov hauv paus. Kov nrog kev saib xyuas kom tiv thaiv kev puas tsuaj rau pob thiab ntim.
