Midabka Fluorescent ee Khadka Daabacaadda
Sharaxaada Alaabta:
SHT Fluorescent Dissolving Nuxurka Midabka waa mid aad u hufan, midabkiisu sarreeyo kaas oo si buuxda ugu milmay dareeraha. Waxay ku habboon tahay in loo isticmaalo warqad-pressure-ku-saleysan iyo khadadka gravure daabacaadda waraaqaha duuban ee kala duwan, filimada hufan iyo biraha birta, iyo sidoo kale khadadka UV-la daweyn karo. Khadadka fluorescent-ka ee lagu sameeyay isku-ururinta midabka LNT-ku-saleysan waxay leeyihiin saameyn cad oo fluorescent waxaana loo isticmaali karaa baakadaha hadiyadda, warqadaha nudaha, sumadaha, alaabada balaastiigga ah, alaabada dhalooyinka iyo alaabta alwaax.
Midabka SHT-da ayaa si aan kala go 'lahayn loogu xiri karaa khadadka xarfaha, oo ay ku jiraan: nitrocellulose, cellulose, acetate cellulose, butyrate, acrylic fibers, resins ketone iyo resins polyamide. Si loo kordhiyo caabbinta waxyeellada, nabarrada, biyaha iyo silbashada, xaddi yar oo wax lagu daro ayaa lagu dari karaa.
Codsiga ugu muhiimsan:
(1) ku haboon in loo isticmaalo warqad-pressure-ku-saleysan iyo khad-qurux
(2)Daabacaadda waraaqo wax lagu duubo oo kala duwan, filimaan hufan iyo biro
(3) Khadadka UV-la daweyn karo
(4) loo isticmaalo baakadaha hadiyadda, waraaqaha nudaha, calaamadaha, alaabada balaastiigga ah, alaabta dhalooyinka iyo alaabta alwaax
Soo jeedin qaabeynta:
Midabka SHT ayaa horay loogu milmay iyadoo la isku daray aalkolo iyo esters. Waxaa lagu talinayaa in la isticmaalo isku dar ah qiyaastii 30% ethanol anhydrous ama n-propanol leh 70% ethyl acetate ama isopropyl acetate ka dibna ku dar xirayaasha iwm si aad u sameysid khad daabacan.
(Fiiro gaar ah: Macmiilku waxa uu isticmaali karaa dareerayaal kale oo leh polarity ka xoog badan si uu u milmo, marka uu sii xoogeysto waxqabadka dareeraha ayaa si degdeg ah u kordhiya xawaaraha kala dirida.)
