Thaum cov hlau octoate driers tau muab tso rau hauv alkyd coatings raws li me me additives (feem ntau 0.01-0.1% hlau ntawm txheej), cov concentration ntawm ib tug neeg Repr. 1B tivthaiv nyob rau hauv qhov kawg sib tov yog feem ntau zoo nyob rau hauv lub 0.3% qhov pib uas ua rau labeling - tab sis cov formulators yuav tsum xam qhov tseeb concentration nyob rau hauv lawv cov ntsiab lus. Sinolook muab kev sib xyaw ua ke ntawm kev suav cov lus qhia ntawm kev thov.
Cov kua qaub ntawm 2-EHA yog dab tsi thiab kuv yuav siv nws li cas hauv cov hlau octoate synthesis?
Theoretical AV rau 100% ntshiab 2-EHA (MW 144.21 g / mol) yog 56,100 / 144.21 =389 mg KOH/g. Sinolook's specification targets 385–392 mg KOH/g, bracketing theoretical value with allowance for trace C8 isomers and 2-ethylhexanol. Hauv cov hlau octoate synthesis, tus nqi 2-EHA yog xam raws li: moles ntawm 2-EHA ib kg=AV / 56.1. Ib txwm siv lubCOA acid tus nqi rau cov khoom tshwj xeeb- tsis yog nominal 389 - vim hais tias ib tug 5 mg KOH/g AV variation sib raug mus rau ~ 1.3% variation nyob rau hauv lub xam 2-EHA nqi, ncaj qha cuam tshuam cov ntsiab lus hlau thiab dawb acid nyob rau hauv cov khoom. Dawb acid ntau dhau ua rau kev tsim kho xim thiab cov khoom tsis ruaj khov; hlau oxide ntau dhau ua rau haze thiab nag lossis daus.
2-EHA puas tuaj yeem siv rau hauv daim ntawv thov kev sib cuag zaub mov - xws li cov roj nplua nyeem rau cov khoom siv ua zaub mov?
2- EHA'sRepr. 1B (H360D) kev faib tawm txhais tau tias txhob txwm koom ua ke rau hauv daim ntawv thov kev sib cuag zaub mov yuav tsum tau ua tib zoo saib xyuasnyob rau hauv txhua txoj cai.
