Rarraba Rini Mai Aiki

Rarraba Rini Mai Aiki

Dangane da ƙungiyoyin masu amsawa daban-daban, za a iya raba rini masu amsawa zuwa nau'i biyu: nau'in triazene na simmetric da nau'in vinylsulfone.

Nau'in triazene na simmetric: A cikin irin wannan nau'in rini mai amsawa, abubuwan sinadarai na atom ɗin chlorine masu aiki sun fi aiki.A lokacin aikin rini, ana maye gurbin ƙwayoyin chlorine da filaye na cellulose a cikin matsakaici na alkaline kuma su zama ƙungiyoyi masu barin.Halin da ke tsakanin rini da fiber cellulose shine yanayin maye gurbin bimolecular nucleophilic.

Vinyl sulfone nau'in: vinyl sulfone (D-SO2CH = CH2) ko β-hydroxyethyl sulfate sulfate.A lokacin aikin rini, β-hydroxyethyl sulfate sulfate yana hazo a cikin matsakaicin alkaline don samar da ƙungiyar vinyl sulfone.Rukunin sulfone na vinyl yana haɗuwa tare da fiber cellulose don jurewa ƙarar nucleophilic don samar da haɗin gwiwa.

Rini biyu masu amsawa da aka ambata a sama sune manyan nau'ikan rini masu amsawa waɗanda suka fi girma a duniya.Domin inganta matakan gyaran rini na amsawa, an shigar da ƙungiyoyi biyu masu amsawa a cikin kwayoyin rini a cikin 'yan shekarun nan, wato rini mai amsawa biyu.

Ana iya raba rini masu amsawa zuwa jeri da yawa bisa ga ƙungiyoyin masu amsawa daban-daban:

1. Rini mai amsawa nau'in X yana ƙunshe da ƙungiyar masu amsawar dichloro-s-triazine, wanda shine rini mai ƙarancin zafin jiki, wanda ya dace da rina fiber cellulose a 40-50 ℃.

2. K-type reactive rini ya ƙunshi monochlorotriazine reactive rukuni, wanda shi ne babban zafin jiki reactive rini, dace da bugu da pad rini na auduga yadudduka.

3. Nau'in KN rini mai amsawa sun ƙunshi ƙungiyoyi masu amsawa na hydroxyethyl sulfone sulfate, waɗanda sune rini mai ɗaukar zafi na tsakiya.Zazzabi na rini shine 40-60 ℃, dace da rini na auduga, rini mai girma mai sanyi, da bugun rini a matsayin launi na bango;kuma dace da rini na hemp textiles.

4. Nau'in M-nau'in rini mai amsawa ya ƙunshi ƙungiyoyi masu amsawa guda biyu kuma yana cikin rini mai amsawa na tsakiya.Yanayin zafin jiki shine 60 ° C.Ya dace da matsakaicin zazzabi bugu da rini na auduga da lilin.

5. Nau'in KE reactive dyes ya ƙunshi ƙungiyoyi masu amsawa biyu kuma suna cikin rini mai ɗaukar zafi mai zafi, waɗanda suka dace da rini auduga da yadudduka na lilin.

Halaye

1. Rini na iya amsawa tare da fiber don samar da haɗin gwiwa.A cikin yanayi na al'ada, wannan haɗin ba zai rabu ba, don haka da zarar an yi rina fenti a kan fiber, zai sami saurin launi mai kyau, musamman rigar magani.Bugu da ƙari, fiber ɗin ba zai yi karyewa ba kamar wasu rini na vatawa bayan rini.

2. Yana da kyakkyawan aikin daidaitawa, launuka masu haske, haske mai kyau, sauƙin amfani, cikakken chromatogram, da ƙananan farashi.

3. An riga an samar da shi da yawa a kasar Sin, wanda zai iya cika bukatun masana'antar bugu da rini;yana da fa'idar amfani da yawa, ba kawai don rini na zaruruwan cellulose ba, har ma da rini na zaruruwan furotin da wasu masana'anta masu gauraya.
