Kupanga Chitoliro Champhamvu “Chitetezo”

Zokwezedwa mu Tekinoloje ya Steel Pipe Anticorrosion Tetezani Chitetezo ndi Umoyo Wamagalimoto Amakampani
M'magawo a petrochemical, madzi am'matauni, ndi kayendedwe ka gasi, mapaipi achitsulo, monga magalimoto oyambira, amakumana ndi zovuta zingapo, kuphatikiza kuwonongeka kwa nthaka, kukokoloka kwa media, ndi okosijeni wam'mlengalenga. Deta ikuwonetsa kuti moyo wanthawi zonse wamapaipi achitsulo osagwiritsidwa ntchito ndi osakwana zaka zisanu, pomwe wanthawi zonse wamankhwala oletsa kutukula amatha kupitilira zaka 20. Ndi kukweza kwa mafakitale komanso kufunikira kwa chitetezo cha chilengedwe, ukadaulo wa chitoliro chachitsulo wasintha kuchoka pachitetezo chotchinga chimodzi kupita pagawo latsopano lachitetezo chamoyo wonse chomwe chimaphatikizapo "kukweza kwazinthu, kukhathamiritsa kwazinthu, ndi kuyang'anira mwanzeru."

Pakadali pano, matekinoloje apamwamba achitsulo oletsa kuwononga chitoliro amapereka mitundu yosiyanasiyana yamakina ogwirizana ndi zochitika zinazake. M'gawo la mapaipi okwiriridwa, 3PE (zokutira za polyethylene zosanjikiza zitatu) zokutira zotsutsana ndi dzimbiri ndiye njira yabwino yothetsera mapaipi amafuta ndi gasi mtunda wautali chifukwa chokana kupsinjika kwa nthaka komanso kutha kwa cathodic. Mapangidwe awo, opangidwa ndi epoxy ufa woyambira, zomatira zapakati, ndi wosanjikiza wakunja wa polyethylene, zimapereka dzimbiri komanso chitetezo champhamvu. Kwa mapaipi a asidi ndi amchere m'makampani opanga mankhwala, zokutira za fluorocarbon ndi pulasitiki zimapatsa ubwino. Zoyambazo zimathandizira kuti ma fluororesis azitha kukana zowononga kwambiri, pomwe omaliza amapatula zowulutsa kuchokera ku chitoliro chachitsulo pomanga khoma lamkati ndi zinthu monga polyethylene ndi polytetrafluoroethylene. Kuphatikiza apo, galvanizing yotentha yotentha imagwiritsidwa ntchito kwambiri m'malo owononga pang'ono monga madzi am'matauni ndi ngalande zamadzi ndi zida zothandizira zitsulo chifukwa chotsika mtengo komanso kuyika kwake kosavuta. The nsembe anodic zochita za wosanjikiza nthaka amapereka yaitali electrochemical chitetezo kwa chitoliro zitsulo.

Kupititsa patsogolo kwaukadaulo ndi njira zatsopano zogwirira ntchito zikuyendetsa bwino paipi yachitsulo yolimbana ndi dzimbiri. Njira zachikale zopenta pamanja, chifukwa cha zovuta monga makulidwe omata komanso kusamata bwino, pang'onopang'ono zimasinthidwa ndi mizere yopangira makina. Masiku ano kupopera mbewu mankhwalawa mopanda mpweya komanso matekinoloje opopera opanda mpweya amatha kukwaniritsa kulekerera makulidwe mkati mwa ± 5%. Pankhani ya zinthu zotsutsana ndi dzimbiri, zokutira za epoxy zokhala ndi chilengedwe zokhala ndi madzi komanso zokutira zothina ndi graphene-zosinthidwa pang'onopang'ono zimasintha zokutira zosungunulira, kuchepetsa kutulutsa kwa VOC ndikuwongolera kukana kwanyengo kwa zokutira komanso kukana kuvala. Panthawi imodzimodziyo, njira zowunikira mwanzeru zikuyamba kuphatikizidwa mu machitidwe odana ndi kutu. Mapaipi achitsulo m'mapulojekiti ena ofunikira tsopano ali ndi masensa owononga dzimbiri. Masensawa amatenga nthawi yeniyeni ya dzimbiri komanso ma siginecha owonongeka kuchokera pakhoma lakunja kwa mapaipi, zomwe zimapatsa chenjezo lachiwopsezo cha kuwonongeka kwa dzimbiri ndi kukonza bwino.

Kwa ntchito zachitsulo zotsutsana ndi chitoliro, mgwirizano wamakampani ndi wakuti "30% zipangizo, 70% yomanga." Pamaso kumanga, zitsulo chitoliro pamwamba ayenera sandblasted kuchotsa dzimbiri ndi kuonetsetsa padziko roughness wa Sa2.5 kapena apamwamba. Mankhwalawa amachotsanso zonyansa monga mafuta, sikelo, ndi zonyansa zina, ndikutsegulira njira yomatira. Pakumanga, makulidwe a zokutira, kutentha kwa machiritso, ndi nthawi ziyenera kuyendetsedwa mosamalitsa kuti pasakhale zolakwika monga ma pinholes ndi kutayikira. Mukamaliza, mphamvu ya anti-corrosion iyenera kutsimikiziridwa kudzera m'njira monga kuyesa spark ndi kuyesa kumamatira. Pokhapokha pokhazikitsa ndondomeko yokwanira, yotsekedwa yophatikizapo "kusankha zinthu - chithandizo chapamwamba - kasamalidwe ka zomangamanga ndi kulamulira - kukonzanso pambuyo" kungatheke kuti phindu la nthawi yayitali la chitoliro chotsutsana ndi dzimbiri lidziwike.

Ndi kupita patsogolo kwa zolinga za "dual carbon" ndikuwonjezera zofunikira za chitetezo cha mafakitale, teknoloji yotsutsa chitoliro chachitsulo idzapitirizabe kusinthika kupita ku njira zobiriwira, zogwira mtima komanso zanzeru. M'tsogolomu, zipangizo zatsopano zotsutsana ndi zowonongeka zomwe zimagwirizanitsa katundu wa carbon wochepa ndi chitetezo cha nthawi yaitali, komanso machitidwe owonetsetsa oletsa kuwononga omwe amaphatikiza teknoloji yamapasa a digito, adzakhala ofunika kwambiri pa kafukufuku wamakampani ndi chitukuko. Izi zidzapereka chishango cholimba cha chitetezo cha mapaipi osiyanasiyana a mafakitale ndikuthandizira pa ntchito yapamwamba ya zomangamanga.
