Kuwunika kwa njira yochizira pamwamba pazitsulo zopangira malata pamaso pa kujambula

Kutentha-kuviika galvanizing (kutentha-kuviika galvanizing kwaifupi) pamwamba pa zitsulo kabati ndi yofala kwambiri komanso yothandiza pamwamba chitetezo luso kulamulira dzimbiri chilengedwe cha mbali zitsulo. Nthawi zambiri mumlengalenga, kutentha-kuviika galvanizing ❖ kuyanika akapeza luso imeneyi akhoza kuteteza mbali zitsulo kuti dzimbiri kwa zaka zingapo kapena zaka zoposa 10. Pazigawo zopanda zofunikira zotsutsana ndi dzimbiri, palibe chifukwa cha chithandizo chachiwiri cha anti-corrosion (kupopera kapena kujambula). Komabe, kuti apulumutse ndalama zoyendetsera zipangizo ndi zipangizo, kuchepetsa kukonza, ndi kuonjezera moyo wautumiki wa zitsulo zopangira zitsulo m'madera ovuta, nthawi zambiri zimakhala zofunikira kuchita chitetezo chachiwiri pazitsulo zotentha zachitsulo, ndiko kuti, kugwiritsa ntchito zokutira zamtundu wa chilimwe pamtunda wotentha wothira malata kuti apange dongosolo la anti-corrosion lachiwiri-wosanjikiza.
Nthawi zambiri, ma gratings achitsulo nthawi zambiri amadutsa pa intaneti atangotha ​​​​kuwotcha. Pa passivation ndondomeko, ndi makutidwe ndi okosijeni anachita padziko otentha-kuviika galvanizing ❖ kuyanika ndi mawonekedwe a njira passivation, kupanga wandiweyani ndi mwamphamvu amamatira passivation filimu padziko otentha-kuviika galvanizing wosanjikiza, amene amathandiza kuti utithandize kukana dzimbiri wa nthaka wosanjikiza. Komabe, pazitsulo zazitsulo zomwe zimafunika kuti zikhale ndi chiyambi cha chilimwe kuti zitetezeke, filimu yowonongeka, yosalala, komanso yopanda phokoso yachitsulo imakhala yovuta kuti ikhale yogwirizana kwambiri ndi chiyambi cha chilimwe, zomwe zimabweretsa kuphulika msanga ndi kukhetsa kwa zokutira organic panthawi ya utumiki, zomwe zimakhudza chitetezo chake.
Pofuna kupititsa patsogolo kulimba kwazitsulo zazitsulo zomwe zimagwiritsidwa ntchito ndi galvanizing yotentha, nthawi zambiri zimakhala zotheka kuvala chovala choyenera cha organic pamwamba pake kuti chikhale chotetezera chitetezo. Popeza kuti pamwamba pa kutentha-kuviika kanasonkhezereka wosanjikiza zitsulo kabati ndi lathyathyathya, yosalala, ndi belu woboola pakati, ndi kugwirizana mphamvu pakati pa izo ndi wotsatira dongosolo ❖ kuyanika ndi osakwanira, amene mosavuta kubweretsa kuwira, kukhetsa, ndi kulephera msanga kwa ❖ kuyanika. Posankha choyambira choyenera kapena njira yoyenera yopangira mankhwala, mphamvu yomangirira pakati pa zokutira za zinki / zokutira zoyambira zimatha kuwongolera, ndipo chitetezo chanthawi yayitali chachitetezo chophatikizika chikhoza kuperekedwa.
Ukadaulo wofunikira womwe umakhudza chitetezo cha chitsulo chosungunula chotenthetsera chachitsulo chotchinga pamwamba pachitetezo choteteza ndichonso chithandizo chapamwamba chisanachitike. Sandblasting ndi imodzi mwa anthu ambiri ntchito ndi odalirika pamwamba mankhwala njira ❖ kuyanika zitsulo grating, koma chifukwa otentha-kuviika kanasonkhezereka pamwamba ndi wofewa, mopitirira muyeso sandblasting kuthamanga ndi mchenga tinthu kukula zingachititse imfa ya kanasonkhezereka wosanjikiza wa zitsulo kabati. Ndi kulamulira kupsyinjika kutsitsi ndi kukula kwa mchenga tinthu, zolimbitsa sandblasting padziko otentha-kuviika kanasonkhezereka zitsulo kabati ndi ogwira pamwamba mankhwala njira, amene ali ndi zotsatira zokhutiritsa pa kuwonetsera koyambirira, ndi mphamvu yomangira pakati pa izo ndi otentha-kuviika kanasonkhezereka wosanjikiza ndi wamkulu kuposa 5MPa.
Pogwiritsa ntchito cyclic hydrogen primer yokhala ndi zinc phosphate, kumamatira pakati pa zokutira zinki / organic primer ndikokulirapo kuposa 5MPa popanda kuphulika mchenga. Pamwamba pazitsulo zotentha zachitsulo, pamene sikoyenera kugwiritsa ntchito mankhwala a sandblasting pamwamba, pamene kupaka kwina kwa organic kumaganiziridwa pambuyo pake, choyambira chokhala ndi phosphate chingasankhidwe, chifukwa phosphate mu primer imathandizira kuti filimu ya utoto ikhale yomatira ndikuwonjezera mphamvu ya anti-corrosion.
Pamaso poyambira ntchito pomanga ❖ kuyanika, otentha-kuviika kanasonkhezereka wosanjikiza wa zitsulo grating ndi passivated kapena si passivated. Kukonzekerako sikumakhudza kwambiri kumamatira, ndipo kupukuta mowa kulibe zotsatira zoonekeratu pa mphamvu yomangira pakati pa zokutira zinki / primer.
