Sezvo isu tese tinoziva, welded simbi pombi inoita ngura nekufamba kwenguva iri kushandiswa. Nezve kuchengetedzwa kwekuora kwepombi mumapurojekiti, kune akawanda marudzi ekuputira uye kuputira anoshandiswa mumashandisirwo nhasi. Sezvo mutemo, machira ane maviri ekutanga mabasa: kushongedza nekudzivirira izvo zvine kukosha kwehupfumi. Mabatiro anoshanda anogona kushandiswa kushandura nzvimbo yepasi peiyo substrate, senge adhesion, wetability, corrosion resistance, kana kupfeka kuramba.
Parizvino, galvanization inonyanya kufarirwa inoshandiswa muindasitiri yesimbi pombi, iyo inoumba yakasimba kudzivirira yakatenderedza muviri wesimbi mukugadzira maitiro. Semuyenzaniso, inopisa yakanyudzwa galvanized simbi pombi sepombi yesimbi yakajairika muindasitiri yepombi yesimbi sezvainonyikwa mudhishi resimbi yakanyungudutswa kana kushandisa nzira dze electroplating muchigayo kuitira kuwedzera hupenyu hwebasa resimbi nekudzivirira. ngura kune mamwe maapplication. Kunze kwezvo, vasati vatumira mapaipi, vagadziri vepombi dzesimbi vanowanzopfekedza simbi yacho neoiri kuti vadzore kupindirana kwezingi nemhepo. Kana mafuta aya apera, kuita kwezingi neokisijeni kunogadzira firimu rakacheneruka rinoshandura ruvara rwesimbi kubva kune grey kuenda kune isinganakidze kuchena-grey. Kana pombi yesimbi yakabatiswa ichida kutengwa kunze kwenyika, rudzi urwu rwepombi kazhinji rine firimu rinodzivirira simbi kubva mukuora munzvimbo yemvura yemunyu sezvo simbi inofamba ichiyambuka makungwa kana nyanza pazvikepe zvinotakura zvinhu. Kana yaiswa kunze, iyi passivator ichaenda kunze mumwedzi mitanhatu; nokuda kwekushandiswa kwemukati, inogona kubviswa nekugadzirisa pamusoro ne phosphoric acid solution.
Pamusoro pezvo, kupeta kwependi kana kupfekedza hupfu ndeimwe nzira mbiri dzakakurumbira dzekudzivirira pombi yesimbi yakashongedzwa kubva mukuora, pamwe nekuchengetedza chitarisiko chakanaka chepombi iri kushandiswa nhasi. Kunyanya pendi masisitimu anoshandiswa zvakanyanya kune zvivakwa zvesimbi akagadzirwa mumakore apfuura kuti aenderane nemutemo wezvemamiriro ekunze uye mukupindura kune zvinodiwa kubva kubhiriji uye varidzi vezvivakwa zvekuvandudza kusimba kwekuita. Muzvirongwa zvakawanda zvekuvaka, pombi dzesimbi dzakapendwa dzakapendwa neruvara rwekuti dzirambe dzichitaridzika zvakanaka dzichishandiswa. Iyo inodzivirira pendi masisitimu anowanzo sanganisira primer, undercoat (s) uye majasi ekupedzisa. Imwe neimwe yekuputira 'layer' mune chero inodzivirira system ine basa chairo, uye mhando dzakasiyana dzinoiswa mune imwe kutevedzana kweprimer inoteverwa nepakati / kuvaka majasi muchitoro, uye pakupedzisira kupedzisa kana bhachi repamusoro mungave muchitoro kana panzvimbo. .
DongPengBoDa Steel Pipe Group, semumwe wevagadziri vepombi dzesimbi vane mukurumbira muChina, inopa mhando dzakasiyana dzesimbi pombi kurapwa masevhisi, anosanganisira gasi, oiri, mvura uye mamwe madhiri ane anoshingirira mukuora kubva kunyoro, makemikari nezvimwe zvinokuvadza. Zvigadzirwa zvedu zvine akawanda akasiyana maficha seanotevera:
1. Yakanakisa corrosion resistance: yakanakisa kuramba kune acids uye alkalis, uye inovimbisa hupenyu hwesevhisi hurefu pasi pemamiriro evhu anoora zvakanyanya;
2. Kubata kwakasimba: primer uye adhesive layer inopa kusungirirwa kwakasimba pasi pehupamhi hwekushisa kwebasa;
3. Kugadzirisa nyore: kukanganisa kwepamusoro kunogona kuitika panguva yekufambisa, kuchengetwa kwepombi kunogona kugadziriswa nyore nyore;
4. Internal coating: yakanakisa corrosion resistance uye inoderedza kupesana kwekupokana kwe welded simbi pombi mumashandisirwo.
