Simbi grating ine mabhenefiti ekuchengetedza simbi, kusadzivirirwa nekuora, kuvaka nekukurumidza, kushambidzika uye kwakanaka, kusatsvedza, kufefetedza, hapana mazino, hapana kuunganidzwa kwemvura, hapana kuunganidza guruva, kusagadzirisa, uye hupenyu hwesevhisi anopfuura makore makumi matatu. Iri kuwedzera kushandiswa zvakanyanya nezvikamu zvekuvaka. Iyo yepamusoro yesimbi grating inobatwa, uye chete mushure meimwe kurapwa kwakakosha kunogona kuwedzera hupenyu hwayo hwebasa. Mamiriro ekushandiswa kwesimbi grating mumaindasitiri emaindasitiri anowanzo kuvhurika-mhepo kana munzvimbo dzine mhepo uye yepakati corrosion. Nokudaro, kurapwa kwepamusoro kwesimbi yesimbi yakakosha zvikuru kuhupenyu hwebasa resimbi grating. Izvi zvinotevera zvinounza nzira dzakawanda dzakajairika dzekurapa pamusoro pesimbi grating.
(1) Kupisa-dip galvanizing: Kupisa-dip galvanizing ndiko kunyudza simbi inobviswa ngura mumhepo yakanyungudutswa yezinc fluid inenge 600℃, kuitira kuti zinc layer inonamirwa pamusoro perata resimbi. Ukobvu hwezinc layer haifanire kunge iri pasi pe65um kune mahwendefa matete ari pasi pe5mm, uye kwete pasi pe86um pamahwendefa akakora. Nekudaro kuzadzisa chinangwa chekudzivirira ngura. Zvakanakira nzira iyi ndeyekugara kwenguva refu, yakakwirira dhigirii yeindasitiri yekugadzira, uye yakagadzikana mhando. Nokudaro, inoshandiswa zvakanyanya mumapurojekiti ekunze esimbi ekugadzira iyo yakasvibiswa zvakanyanya nemhepo uye yakaoma kuchengetedza. Nhanho yekutanga yekupisa-dip galvanizing ndeye pickling uye kubvisa ngura, inoteverwa nekuchenesa. Kusakwana kwematanho maviri aya kuchasiya njodzi dzakavanzika dzekudzivirira ngura. Nokudaro, dzinofanira kubatwa zvakakwana.
(2) Kupisa-yakapfapfaidza aluminium (zinc) yakasanganiswa coating: Iyi inzira yenguva refu yekudzivirira ngura ine imwechete inodzivirira corrosion maitiro sekupisa-dip galvanizing. Iyo chaiyo nzira ndeyekutanga jecha pamusoro peiyo simbi gireti kubvisa ngura, kuitira kuti pamusoro panoratidza simbi inopenya uye roughens. Zvadaro shandisa murazvo weacetylene-oxygen kunyungudutsa waya yealuminium (zingi) inoramba ichiunzwa, woifuridzira pamusoro perata nemhepo yakamanikidzwa kuita muzinga wealuminium (zinc) wekupfapfaidza (ukobvu hunosvika 80um~100um). Pakupedzisira, zadza macapillaries nemajasi akadai se cyclopentane resin kana urethane rubber pendi kuti uite chipfeko chinosanganiswa. Kubatsira kweiyi nzira ndeyokuti ine simba rinogadziriswa nehukuru hwesimbi yesimbi, uye chimiro uye hukuru hwesimbi yesimbi inenge isingabvumirwi. Imwe bhenefiti ndeyokuti kupisa kwekuita kweichi chiitiko ndekwenzvimbo uye kunomanikidzirwa, saka hazvizokonzerese kupisa deformation. Kuenzaniswa nekupisa-dip galvanizing yesimbi grating, nzira iyi ine dhigirii yakaderera yeindasitiri, uye kusimba kwekushanda kwejecha uye aluminium (zinc) kuputika kwakakwira. Hunhu hunobatwawo nyore nekuchinja kwemaitiro emushandisi.
(3) Nzira yekuputira: Kudzivirirwa kwemaitiro ekuputira kazhinji hakuna kunaka seyekureba-kuora kuramba nzira. Iine mutengo wakaderera wenguva imwe chete, asi mutengo wekugadzirisa wakakwira kana uchishandiswa kunze. Nhanho yekutanga yenzira yekuputira ndeyekubvisa ngura. Zvipfeko zvemhando yepamusoro zvinotsamira pakubvisa ngura zvakakwana. Naizvozvo, machira anodiwa zvakanyanya anowanzo shandisa jecha uye kuputika kwepfuti kubvisa ngura, kuratidza kupenya kwesimbi, uye kubvisa ngura nemafuta ese. Kusarudzwa kwekuputira kunofanira kufunga nezvenharaunda yakapoteredza. Zvipfeko zvakasiyana zvine kushivirira kwakasiyana kune mamiriro akasiyana ekuora. Coatings anowanzo kupatsanurwa kuva primers (layers) uye topcoat (layers). Maprimers ane hupfu hwakawanda uye mashoma base zvinhu. Iyo firimu ine rough, ine kunamatira kwakasimba kusimbi, uye ine chisungo chakanaka netopcoats. Majasi epamusoro ane zvimwe zvigadziko, ane mafirimu anopenya, anogona kudzivirira maprimers kubva mukuora kwemuchadenga, uye anogona kuramba mamiriro ekunze. Pane dambudziko rekuenderana pakati pezvipfeko zvakasiyana. Paunosarudza zvipfeko zvakasiyana zvisati zvaitika uye shure, teerera kuenderana kwavo. Kuvakwa kwekuputira kunofanirwa kuve nekushisa kwakakodzera (pakati pe5 ~ 38 ℃) uye humidity (hunyoro husingapfuuri 85%). Nzvimbo yekuvaka yekuputira inofanira kunge isina guruva shoma uye hapafaniri kuva nekugadzirisa pamusoro pechikamu. Haifanirwe kunaya mukati memaawa mana mushure mekupfeka. Iyo yekupfeka inowanzoiswa 4 ~ 5 nguva. Huwandu hwese hwefirimu rependi yakaoma 150um yemapurojekiti ekunze uye 125um yemapurojekiti emukati, nekutsauka kunobvumidzwa kwe25um.
