Mawu Oyamba
Pigment Black 28 ndi inorganic Pigment yomwe imagwiritsidwa ntchito kwambiri yokhala ndi formula yamankhwala (CuCr2O4). Zotsatirazi ndikuwulula za chilengedwe, kagwiritsidwe ntchito, kapangidwe ndi zambiri zachitetezo cha Pigment Black 28:
Chilengedwe:
- Pigment Black 28 ndi wobiriwira wobiriwira mpaka Wakuda waufa wolimba.
-Ali ndi kuphimba bwino komanso kukhazikika kwamtundu.
-Kulimba kwa asidi ndi alkali kukana, kukana dzimbiri bwino.
-Ili ndi kukana kwabwino kwa kuwala komanso kukana kutentha.
Gwiritsani ntchito:
- Pigment Black 28 imagwiritsidwa ntchito kwambiri mu utoto, zokutira, mapulasitiki, mphira, zoumba, magalasi ndi magawo ena kuti apatse zinthu zobiriwira Zakuda kapena zobiriwira.
- Amagwiritsidwa ntchito ngati pigment wakuda pamapepala ndi mafakitale osindikizira.
- Itha kugwiritsidwanso ntchito kupaka utoto ndi kukongoletsa zadothi ndi magalasi.
Njira:
- Pigment Black 28 ikhoza kupezedwa ndi kaphatikizidwe kazinthu. Njira yodziwika bwino ndiyo kutengera mchere wamkuwa (monga copper sulfate) ndi mchere wa chromium (monga chromium sulfate) pansi pamikhalidwe yoyenera kupanga Pigment Black 28.
Zambiri Zachitetezo:
- Pigment Black 28 nthawi zambiri imawonedwa ngati yopanda vuto, koma ikakokedwa kapena kuchulukitsidwa kwambiri, imatha kuvulaza thanzi la munthu, chifukwa chake izi ziyenera kutsatiridwa mukamagwiritsa ntchito:
- Pewani kutulutsa ufa wa Pigment Black 28 ndikuvala chigoba choyenera pogwira ntchito.
- kupewa yaitali khungu kukhudzana, ngati pali kukhudzana ayenera yomweyo kutsukidwa ndi madzi.
- Pewani kukhudzana ndi asidi, alkali ndi zinthu zina panthawi yosungiramo kuti mupewe zotsatira zosatetezeka.
-Werengani mosamala malangizo okhudzana ndi chitetezo ndi malangizo ogwiritsira ntchito musanagwiritse ntchito, ndikuchitapo kanthu zodzitetezera.
