Gulu la Reactive Dyyeing
Malinga ndi magulu osiyanasiyana otakataka, utoto wokhazikika ukhoza kugawidwa m'mitundu iwiri: mtundu wa symmetrical triazene ndi mtundu wa vinylsulfone.
Symmetric triazene mtundu: Mu mtundu uwu wa utoto wotakataka, mankhwala a maatomu a klorini akugwira ntchito kwambiri.Panthawi yopaka utoto, maatomu a chlorine amasinthidwa ndi ulusi wa cellulose mu sing'anga yamchere ndikukhala magulu osiya.Zomwe zimachitika pakati pa utoto ndi ulusi wa cellulose ndi bimolecular nucleophilic substitution reaction.
Mtundu wa vinyl sulfone: vinyl sulfone (D-SO2CH = CH2) kapena β-hydroxyethyl sulfone sulfone.Panthawi yopaka utoto, β-hydroxyethyl sulfone sulfate imalowa mumchere wa alkaline kupanga gulu la vinyl sulfone.Gulu la vinyl sulfone limaphatikizana ndi ulusi wa cellulose kuti zigwirizane ndi nucleophilic add reaction kuti apange covalent chomangira.
Mitundu iwiri yotulutsa mphamvu yomwe tatchulayi ndiyo mitundu ikuluikulu ya utoto wokhazikika womwe umatuluka kwambiri padziko lonse lapansi.Pofuna kuwongolera kuchuluka kwa utoto wokhazikika, magulu awiri osinthika alowetsedwa mu molekyulu ya utoto m'zaka zaposachedwa, omwe ndi utoto wapawiri.
Utoto wokhazikika ukhoza kugawidwa m'magulu angapo malinga ndi magulu awo osinthika:
1. Mtundu wa X-reactive utoto uli ndi gulu lokhazikika la dichloro-s-triazine, lomwe ndi utoto wocheperako wotenthetsera, woyenera kupaka utoto wa cellulose pa 40-50 ℃.
2. Mtundu wa K-reactive utoto uli ndi gulu lokhazikika la monochlorotriazine, lomwe ndi utoto wotentha kwambiri, woyenerera kusindikiza ndi utoto wa pad wa nsalu za thonje.
3. Utoto wamtundu wa KN uli ndi magulu a hydroxyethyl sulfone sulfate, omwe ndi utoto wapakati wotenthetsera kutentha.Kutentha kwa utoto ndi 40-60 ℃, koyenera utoto wa thonje, utoto wambiri wozizira, komanso kusindikiza kwa utoto ngati mtundu wakumbuyo;ndizoyeneranso kuyika utoto wa nsalu za hemp.
4. Mtundu wa M-reactive utoto uli ndi magulu awiri ochitapo kanthu ndipo ndi wa utoto wotentha wapakati.Kutentha kwa utoto ndi 60 ° C.Ndizoyenera kusindikiza kutentha kwapakatikati ndi utoto wa thonje ndi nsalu.
5. Mitundu ya KE yamtundu wa reactive dyes imakhala ndi magulu awiri ogwira ntchito ndipo imakhala yamitundu yotentha kwambiri, yomwe ili yoyenera kuyika thonje ndi nsalu za bafuta.
Makhalidwe
1. Utoto ukhoza kuchitapo kanthu ndi ulusi kuti upange mgwirizano wolumikizana.Munthawi yanthawi zonse, kuphatikiza kumeneku sikungasiyanitse, kotero utoto wokhazikika ukakhala utoto pa ulusi, umakhala ndi mtundu wachangu, makamaka wonyowa.Kuphatikiza apo, ulusiwo sudzakhala wonyezimira ngati utoto wina wa vat ukadaya.
2. Ili ndi magwiridwe antchito abwino, mitundu yowala, yowala bwino, yosavuta kugwiritsa ntchito, chromatogram yathunthu, komanso mtengo wotsika.
3. Ikhoza kupangidwa kale ku China, yomwe ingathe kukwaniritsa zofunikira zamakampani osindikizira ndi opaka utoto;ali ndi ntchito zosiyanasiyana, osati popaka utoto wa ulusi wa cellulose, komanso utoto wa ulusi wa mapuloteni ndi nsalu zina zosakanikirana.
Ndife Reactive Dyes Suppliers.Ngati muli ndi chidwi ndi katundu wathu, chonde omasuka kulankhula nafe.
