Anticorrosion ntchito ya ng'anjo yozungulira
Mng'anjo ya Rotary ndiye chida chofunikira kwambiri pakupanga simenti, ndipo magwiridwe ake okhazikika amagwirizana mwachindunji ndi kutulutsa ndi mtundu wa clinker ya simenti.Komabe, m’zaka zaposachedwapa, pakhala vuto la kaŵirikaŵiri ndi chigoba cha ng’anjo yozungulira, monga kupindika, ming’alu, ngakhale kung’ambika kumene, zomwe zikuchititsa kuti chiwombankhangacho chiwonongeke kwambiri kapena china chilichonse, ngakhalenso vuto la chitetezo.Pali zifukwa zambiri za mavutowa, mongautumikinthawi, nyengo, ntchito ya opareshoni, etc. Chimodzi mwa zinthu zofunika kwambiri ndi dzimbiri la silinda rotary ng'anjo, zomwe zidzapangitsa silinda kukhala woonda ndi kuchepetsa kunyamula mphamvu, kumabweretsa mavuto tatchulawa.
In kuwonjezera pa kutentha kwakukulu, mpweya wina wowononga udzapangidwansoin ndondomeko ya calcinationclinker mu ng'anjo yozungulira, makamaka popanga zinyalala zophatikizika, mipweya yambiri yoyipa monga ma sulfur oxides, nitrogen oxides, hydroxides, chlorine, ndi zina zotero..Mipweya imeneyi imachita zinthu mogwirizana ndi madzi kuti ipange zinthu zowononga kwambiri za acid-base, zomwe zingawononge kwambiri khoma lamkati la ng'anjo yozungulira.Malinga ndi mainjiniya wa fakitale ya simenti, khoma lamkati la ng'anjo yozungulira ya kampaniyo lidapsa ndi 1 mm m'theka la chaka.Ngati palibe njira zoletsa dzimbiri zomwe zatengedwa, ngakhale ng'anjo yatsopano yozungulira imatha kukhala ndi zovuta pakadutsa zaka khumi ikugwiritsidwa ntchito.
Anti-corrosion ya khoma lamkati la ng'anjo yozungulira imatha kugwiritsa ntchito zokutira za SY-zotentha kwambiri zolimbana ndi dzimbiri.Makhalidwe a mankhwalawa ndi awa:
1. Chophimbacho ndi chowuma, cholimba kwambiri, sichimva kuvala komanso chosagwira, komanso chosagwirizana ndi kukokoloka kwa utsi ndi fumbi;
2. Chophimbacho ndi rkugonjetsedwa ndi kutentha kwapakati kutentha kwapakati monga sulfide, nitrogen oxide, HCl gasi ndi mchere wopopera, kugonjetsedwa ndi "mame" amadzimadzi a condensate, komanso kugonjetsedwa ndi kusinthasintha kwa asidi ndi dzimbiri za alkali panthawi ya desulfurization ndi denitrification;
3. Chophimbacho chimakhala ndi moyo wautali wautumiki komanso kukhazikika bwino, ndipo chophimba chowonongeka ndi chosavuta kukonza;
4. High coefficient of linear expansion, good adhesion, and strong kugwirizana mphamvu ndi gawo lapansi;
5. Kutentha kwakukulu kwa kutentha kwa kutentha, kutentha kwa mpweya wa flue kumasinthasintha kwambiri komanso kutsika, ❖ kuyanika sikugwa, ndipo palibe mng'alu;
6. Pamwamba pa filimu yophimba ndi yosalala, yokhala ndi zodzitchinjiriza zodzitchinjiriza ndi anti-tar adhesion.
Zitha kuwoneka kuchokera kuzinthu zomwe zimagwiritsidwa ntchito kuti SY-kutentha kwapamwamba kuvala ndi anti-corrosion kupaka sikungolimbana ndi asidi, alkali ndi kutentha kwakukulu, komanso kumamatira kwabwino, komwe kuli kofanana ndi kuika zovala zotetezera. khoma lamkati la ng'anjo yozungulira, yomwe imatha kukana kwambiri mankhwala ndipkuwonongeka kwa hysical, kutikuteteza ng'anjo yozungulira ku kuwonongeka kwa dzimbiri kwa asidi ndi kutentha kwa alkali.
