Kuvandudzwa kweTekinoroji yeSimbi yeMapaipi eSimbi Kunodzivirira Kukuvara uye Hurefu hweKutakurwa kweMaindasitiri
Muzvikamu zve petrochemical, mvura yemumaguta, uye zvekufambisa gasi rechisikigo, mapaipi esimbi, senzira huru dzekufambisa, anogara achisangana nematambudziko akawanda, anosanganisira ngura yevhu, kukanganiswa kwemidziyo, uye kuoxidation yemhepo. Data rinoratidza kuti avhareji yenguva yebasa remapaipi esimbi asina kugadziriswa isingasviki makore mashanu, nepo iyo yekurapa kwakajairwa kwekudzivirira ngura inogona kuwedzerwa kusvika kumakore anopfuura makumi maviri. Nekuvandudzwa kwemaindasitiri uye zvinodiwa zvakanyanya zvekuchengetedza nharaunda, tekinoroji yekudzivirira ngura yemapaipi esimbi yakashanduka kubva pakudzivirira kwekuvhara kamwe chete kuenda padanho idzva rekudzivirira hupenyu hwese kunosanganisira "kuvandudzwa kwezvinhu, kugadzirisa maitiro, uye kutarisa kwakangwara."
Parizvino, matekinoroji ekudzivirira ngura emapaipi esimbi anopa masisitimu akasiyana-siyana akagadzirirwa mamiriro chaiwo ekushandiswa. Muchikamu chemapaipi akavigwa, machira ekudzivirira ngura e3PE (polyethylene coating matatu) ndiwo mhinduro inofarirwa yemapaipi emafuta negesi ari kure nekuda kwekudzivirira kwawo kwakanyanya kusimba kwevhu uye kupatsanuka kwecathodic. Maumbirwo awo akabatanidzwa, ane hupfu hwe epoxy base, adhesive yepakati, uye layer yekunze ye polyethylene, anopa zvese dziviriro yengura uye impact. Kune mapaipi ane acid nealkaline muindasitiri yemakemikari, machira e fluorocarbon nelayer yepurasitiki zvinopa zvakanakira. Yekutanga inoshandisa makemikari asina simba e fluororesins kudzivirira ngura zvakanyanya, nepo yekupedzisira ichiparadzanisa panyama media inotakurwa kubva papombi yesimbi pachayo nekuisa madziro emukati nezvinhu zvakaita se polyethylene ne polytetrafluoroethylene. Uyezve, hot-dip galvanizing inoshandiswa zvakanyanya munzvimbo dzine ngura zvishoma senge mvura yemuguta uye masisitimu emvura uye tsigiro yechimiro chesimbi nekuda kwemutengo wayo wakaderera uye kuiswa kuri nyore. Kushanda kwe anodic kwe layer ye zinc kunopa dziviriro yenguva refu ye electrochemical yepombi yesimbi.
Kuvandudzwa kwetekinoroji uye kuvandudzwa kwemaitiro kuri kusimudzira kunaka kwepombi yesimbi inodzivirira ngura. Maitiro ekupenda nemaoko echinyakare, nekuda kwematambudziko akadai sekukora kusina kuenzana uye kunamira kusina kunaka, ari kutsiviwa zvishoma nezvishoma nemitsetse yekugadzira otomatiki. Matekinoroji emagetsi anoshandiswa pari zvino uye kupfapfaidza pasina mhepo anogona kuzadzisa kushivirira kwekukora kwepurasitiki mukati me ± 5%. Mumunda wezvinhu zvinodzivirira ngura, machira epoxy anochengetedza mvura uye machira ekudzivirira ngura anogadziriswa ne graphene ari kutsiva zvishoma nezvishoma machira ekudzivirira ngura, achideredza kuburitswa kweVOC uku achivandudza kuramba kwemamiriro ekunze uye kuramba kupfeka kwepurasitiki. Panguva imwe chete, nzira dzekutarisa dzakangwara dziri kutanga kubatanidzwa muhurongwa hwekudzivirira ngura. Mapaipi esimbi mune mamwe mapurojekiti akakosha ikozvino ane masensa ekuparadza. Masensa aya anounganidza masaini ekukuvadza kwepurasitiki uye masaini ekukuvadza kwepurasitiki kubva pamadziro ekunze epaipi, zvichiita kuti yambiro yekutanga yenjodzi dzekukundikana kwepurasitiki uye kugadzirisa kwakanyatsojeka.
Pamapurojekiti ekudzivirira ngura pamapombi esimbi, indasitiri inobvumirana kuti "30% yezvinhu, 70% yekuvaka." Pamberi pekuvaka, pamusoro pepombi yesimbi panofanira kuputirwa jecha kuti pabviswe ngura uye kuve nechokwadi chekuti pamusoro payo pave nekuomarara kweSa2.5 kana kupfuura. Kurapa uku kunobvisawo tsvina dzakadai semafuta, chikero, nezvimwe tsvina, zvichigadzira nzira yekunamatira pakupenda. Munguva yekuvaka, ukobvu hwekupenda, tembiricha yekupisa, nenguva zvinofanirwa kudzorwa zvakasimba kudzivirira zvikanganiso zvakaita semaburi ekupinza uye kubuda kwekupenda. Mushure mekupedzwa, kushanda kwekudzivirira ngura kunofanirwa kusimbiswa kuburikidza nenzira dzakadai sekuyedza spark uye kuyedza kunamira. Nekutanga nzira yakazara, yakavharwa inosanganisira "kusarudza zvinhu - kurapwa kwepamusoro - manejimendi yekuvaka uye kutonga - mushure mekugadzirisa" ndipo panogona kuwanikwa kukosha kwenguva refu kwekudzivirira ngura pamapombi esimbi.
Nekufambira mberi kwezvinangwa zve "dual carbon" uye kuwedzera kwezvinodiwa zvekuchengetedza maindasitiri, tekinoroji yekudzivirira ngura yemapaipi esimbi icharamba ichichinja ichienda kune nzira dzakasvibira, dzinoshanda zviri nani, uye dzakangwara. Mune ramangwana, zvinhu zvitsva zvinodzivirira ngura zvinosanganisa hunhu husina kabhoni yakawanda nedziviriro yenguva refu, pamwe chete nemaitiro ekudzivirira ngura anobatanidza tekinoroji yedhijitari mbiri, zvichave zvinhu zvakakosha pakutsvaga nekusimudzira indasitiri. Izvi zvichapa dziviriro yakasimba yekudzivirira mapaipi akasiyana-siyana emaindasitiri uye zvinobatsira mukushanda kwemhando yepamusoro kwezvivakwa.
