Ol paip bilong stiel i gat sik anti-}korosen stiel em i wanpela samting ol i no inap lusim long wok bilong wokim ol samting bilong nau na wokim ol infrastraksa. Kwaliti blong proses blong fom blong olgeta i diterminem stret seves laef mo sefti pefomens blong olgeta. Taim ol korosen resistens rikwaemen bilong ol paiplain insait long oil, ges, kemikel, na munisipal enjiniaring sekta i wok long go antap yet, ol teknoloji bilong wokim ol samting bilong ol anti-korosen stiel paip tu i wok long go insait long ol nupela samting tu. Dispela atikol bai go insait long as foming proses bilong ol anti-}korosen stiel paip, na givim wanpela komprehensif analisis bilong prodaksen proses stat long ol besik proses i go long ol ki teknikel ditel.
I. Ol As Bilong Ol As Bilong Ol Anti-}korosen Sil Paip
Anti-}korosen steel paip i gat as bilong en i gat wanpela standet stiel paip sabstret i pas wantaim wanpela o moa leit bilong anti-korosen samting long rot bilong wanpela spesifik proses, na kamapim wanpela komposeit straksa bilong "bes samting + anti{3}}korosen leit." As tingting bilong dispela proses bilong kamapim em long lukim olsem ol mekanik samting bilong stiel paip (olsem kompresen na impak resistens) taim em i kontrolim stret adhesen, tiknes yunifomiti, na kemikel stebiliti bilong anti-korosen leit bilong winim longpela{{6}………… lukaut proteksen bilong paip long ol kompleks envairomen (olsem bikpela humiditi, strongpela asit, alkali, na sol sprei).
Tradisenel stiel paip foming i save dipen long wanpela "rol + welding" proses-a steel billet i hot-}}}}rol i go insait long wanpela tubular blank, we bihain ol i weldim o putim i go insait long wanpela hap i stap insait long wanpela paip bodi i go het. Anti{6}}}korosen teknoloji i bildim antap long dispela faundesen, na givim moa korosen resistens long stiel paip long rot bilong tritmen bilong pes, koting, o klading.
II. Ditel Eksplenesen bilong ol wok bilong stretim ol wok bilong kamapim ol samting.
1. Bes Paip Pretritmen: Klinim na Sepim
Strong bilong bon namel long anti-korosen leit na stiel paip i dipen stret long klinpela na rafnes bilong bes paip pes. Sapos i gat residual oil, ros, o skel i stap yet long pes, ol anti-}korosen samting bai no inap pas gut, na dispela i kamapim ol hevi bihain olsem bulging na peeling. Olsem na, pretritmen em i namba wan bikpela step long proses bilong kamapim.
Ol spesifik operesen em:
Mekanikal ros rausim: Sut blasting o sandblasting ikwipmen i yusim hai-spit stiel sut o kwots sand long impaktim steel paip pes, rausim skel na kamapim wanpela yunifom raf pes (planti taim em i nidim wanpela anka mak dip bilong 40-100μm).
Kemikel klinim: Ol ogen solvent (olsem aseton) o asid-bes solusen (olsem fosforik asit) ol i yusim long rausim ol gris i stap yet na liklik ros, na mekim sure olsem pes i no gat ol kontaminen i stap ples klia.
Draim: Hot win o infraret drai i save yusim long kontrolim pes bilong stiel paip i go antap long mak i go daun tru (hamiditi<5%) to prevent bubbles during subsequent coating.
2. Anti-}}}korosen leja foming: skelim bilong ol bikpela proses
Bes long kain bilong anti-korosen materiel na aplikesen senario, foming proses bilong anti-korosen steel paip i ken bruk i go long tripela bikpela daireksen:
(1) Tripela-}laier polietilen (3PE) anti-korosen - dispela proses ol i save yusim moa
3PE anti-}korosen em i wanpela komposit straksa bilong "fusen bond epoksi paura (FBE) daunbilo leit + adhesive namel leya + polietilen ausait leit". Em i bungim bikpela pas bilong epoksi paura wantaim envairomen stres kreking resistens bilong polietilen, na em i gutpela long ol hatpela envairomen olsem ol i planim oil na ges paiplain. Proses blong molding i olsem:
Bes koting: Spreim electrostatically sprei long fused epoksi paura (sais bilong liklik hap i no gat o wankain olsem 150 μm) i go wankain long pre-}tritim steel paip pes, na bihain meltim na strongim em long bikpela tempereja bilong 200-230 digri long kamapim wanpela μm μm;
Intermediet leja koting: Ol i save hatim glu (olsem modified polietilen kopolima) i go long wanpela stet i tanim (olsem 250 digri ) long rot bilong wanpela ekstruda, na bihain ol i putim wankain kot long ausait bilong epoksi leia long rot bilong wanpela mol, wantaim tiknes bilong 170-250 μm;
Ausait leit ekstrusen: Hai-densiti polietilen (HDPE) tu i melt na kotim long rot bilong wanpela ekstruda long kamapim wanpela ausait protektiv leit wantaim tiknes bilong 1.8-3.7 mm (i stap long ol ultraviolet rei na mekanik bagarap).
(2) Epoxy ston kol kol tar anti-}korosen - gutpela bilong liklik na namel (3}}sais diamita paiplain
Dispela proses i yusim epoksi resin na ston kol kol tar olsem ol bikpela raw materiel, na i kamapim wanpela anti{0}}}korosen leit long pes bilong stiel paip long rot bilong brusim o dipim. Ol mak bilong en i no gat bikpela pe, tasol em i save pilim gut temperaja bilong konstraksen envairomen (nidim i mas bikpela moa long 5 digri ) na humiditi, na planti taim ol i save yusim long wara saplai na drenej paip o ol temporari projek.
(3) Simen mota laen - wan saplaemen solusen blong ol spesel senario
For low-pressure pipelines that transport non-corrosive media (such as drinking water), a centrifugal spraying method can be used to evenly adhere cement mortar (water-cement ratio 0.4-0.5) to the inner wall of the steel pipe to form a lining layer with a thickness of 10-30mm. Dispela proses i no gat bikpela pe na i no inap bagarap, tasol em i no gat strong long sakim kemikal korosen.
3. Post-Prosesing mo Testing: Mekem sua se i gat paoa blong Fomem Kwaliti
Bihain long ol i kamapim, ol anti-}korosen koting i go insait long strongpela kwaliti kontrol:
Tiknes Testing: Measem tiknes blong wanwan leja yusum wan magnetik o ultrasonik tiknes gej (eksampol, blong 3PE anti-korosen koting, epoksi leja i mas hae moa o i ikwol long 80μm, mo polietilen leja i mas Bigfala bitim o i ikwol long 2mm).
Testing bilong Adhesen: Verifaem strong bilong bon namel long anti-korosen koting na stiel paip yusim kros-hetch o pulim-of rot (planti taim i nidim Greater winim o wankain olsem 5MPa).
Elektrik Spark Diteksen: Skenim pes bilong anti-korosen koting wantaim wanpela hai-}}voltej prob bilong painim ol pinhol o bagarap (lik poin voltej Gutpela moa o wankain olsem 25kV).
Lukluk long lukluk: Verifaem se i no gat ol defekt olsem ol babol, ol krek, mo ol sag, blong mekem sua se i gat wan smut mo iven fes.
III. Proses Inovesen na Fiuja Trends
Wetem eskalesen blong indastri dimand, proses blong fomem blong korosen-}nesten steel paep i stap jenis i go long hae efisiensi, intelijen teknoloji, mo envaeromen frenli:
Promosen bilong prefabrikesen: Kontiniu prodaksen lain i bungim "stiel paip roling, pretritmen, na anti-korosen koting," na mekim ol prodaksen saikel i sot na kamapim gutpela pasin;
Divelopmen bilong ol nupela anti{0}}}korosen samting: Ol aplikesen olsem nano-}i senis epoksi paura na graphene-enhans polietilen i skruim moa laip bilong korosen (inap long 50 yia o moa);
Eksploresen bilong ol grin proses: Daunim yusim bilong ol ogen solvent (olsem, senisim ol tradisenel solvent- beis koting wantaim wara- beis epoksi koting) i daunim ol VOC emisen.
Konklusen
Proses bilong kamapim bilong korosen-}resistant stiel paip em i wanpela mak bilong intaseksen bilong ol materiel saiens, mekanik manufakturing, na kemikel enjiniaring. Stat long bes paip pretritmen i go long stretpela aplikesen bilong anti-}korosen koting, olgeta step i nidim strongpela kontrol bilong ol paramita na ol ditel. Wetem ol kontinu teknoloji advansmen, ol fiuja korosen-}}}nesten steel paep bae oli no mitim ol besik rikwaemen blong korosen resistens nomo be tu oli kasem ol brekthru long intelijen monitoring (olsem we oli bildim-in korosen sensa) mo laetweit disaen, we i givim moa reliable sapot blong globol infrastrakja konstraksen.
