Ntchito zonse zazolimba machubu opanda msokoayenera kugwira ntchito yolimbana ndi dzimbiri ndi dzimbiri. Ntchito ya anti-corrosion imagawidwa m'njira zitatu:

1. Anti- dzimbiri mankhwala a mapaipi.

Musanayambe kujambula, pamwamba pa payipi iyenera kutsukidwa ndi mafuta, slag, dzimbiri, ndi fumbi la zinki. Muyezo wamtundu wa mankhwala ndi Sa2.5.

2. Pambuyo mankhwala odana ndi dzimbiri pamwamba pa payipi, ntchito topcoat, ndi imeneyi pakati pawo sayenera kupitirira 8 hours. Pogwiritsa ntchito chovala chapamwamba, pamwamba pake payenera kukhala youma ndipo chovalacho chiyenera kukhala chofanana, chozungulira komanso chopanda zotupa ndi mpweya. Mbali zonse ziwiri za chitoliro sayenera kupukuta mkati mwa 150 ~ 250mm.

3. Chovala chapamwamba chikawuma ndi kulimba, ikani utoto ndikumanga mtolo wa nsalu ya fiberglass, ndipo nthawi pakati pa topcoat ndi utoto sayenera kupitirira maola 24.

Kuphwanyika kwa chubu chachitsulo chosasunthika chokhala ndi mipanda:

Pogwiritsira ntchito chubu chachitsulo chosakanizidwa ndi mipanda yokhuthala, nthawi zina pamwamba pamakhala ming'alu yopingasa. Pali zifukwa zambiri za izi. Ndikupatsani kusanthula mwatsatanetsatane pansipa.

Ngati chubu chosasunthika chokhala ndi mipanda yokhuthala sichimapunduka pang'ono panthawi yonse yothira, malo amkati ndi akunja angayambitse kupsinjika kowonjezereka pakukoka kwamkati. Panthawiyi, chifukwa cha kuwonongeka kosauka kwa mapindikidwe, chizolowezi chokulitsa chakunja ndi chachikulu kuposa chamkati, kotero kuti kunja kumapangitsa kuti pakhale kupanikizika kowonjezereka, ndipo mkati mwamkati mumayambitsa kupanikizika kowonjezereka. Ngati kupsinjika kowonjezera kwamkati kumakhala ndi chikoka chachikulu, makamaka kupsinjika kwamphamvu ndi kupsinjika kowonjezereka kumatha kuwonjezeredwa palimodzi, zomwe zitha kupitilira mphamvu yopondereza ya chubu lachitsulo chosakanizidwa ndi mipanda yolimba, zomwe zimapangitsa kuti mkati mwake muphwanyike. pamwamba.

Pansi pamiyezo yofananira yamakina, kuchepetsa zinthu zosiyanasiyana za kupunduka kwa pulasitiki panthawi yopanga ndi kukonza mapaipi achitsulo osakanizidwa ndi mipanda kumawonjezera mwayi wa ming'alu yamkati. Choncho, kupanga wandiweyani-mipanda Seamless zitsulo machubu, quenching khalidwe. Ndikofunikira kwambiri kuchotsa brittleness ya alkaline.

Kuphatikiza pa kupsinjika kowonjezera kwa radial, palinso kupsinjika kwa ma radial panthawi yonse yochotsa. Kung'amba kwautali kumachitika chifukwa cha kupsinjika kowonjezera kwa ma radial komwe kumapangidwa pakukhuthula.
