Imiyoboro irwanya - ruswa ni ibikoresho byingirakamaro mu nganda zigezweho no kubaka ibikorwa remezo. Ubwiza bwibikorwa byabo byerekana ubuzima bwabo bwa serivisi nibikorwa byumutekano. Mu gihe ibisabwa byo kurwanya ruswa bikenerwa mu miyoboro ya peteroli, gaze, imiti, n’ubwubatsi bwa komini bikomeje kwiyongera, ikoranabuhanga mu gukora imiyoboro irwanya - ruswa naryo ririmo guhanga udushya. Iyi ngingo izacengera muburyo bwibanze bwo gukora imiyoboro irwanya - ruswa, itanga isesengura ryuzuye ryibikorwa byakozwe kuva mubikorwa byibanze kugeza kubintu byingenzi bya tekiniki.
I. Amahame shingiro yo Kurwanya - Imiyoboro y'ibyuma
Imiyoboro irwanya - ruswa igizwe ahanini nubutaka busanzwe bwicyuma gishyizwe hamwe nigice kimwe cyangwa byinshi byibikoresho bya anti - byangirika binyuze muburyo bwihariye, bigizwe nuburyo bugizwe n "ibikoresho fatizo + anti - ruswa." Intego nyamukuru yiyi gahunda yo gukora ni ukumenya imiterere yubukorikori bwicyuma (nko gukomeretsa no kurwanya ingaruka) mugihe hagenzurwa neza neza gufatira hamwe, guhuza ubunini, hamwe n’imiti ihamye yo kurwanya ruswa - kugira ngo igere ku gihe kirekire - kurinda igihe kirekire mu miyoboro igoye (nk'ubushuhe bwinshi, aside ikomeye, alkalis, na spray).
Umuyoboro gakondo wibyuma usanzwe ushingiye kubikorwa "kuzunguruka + gusudira" - fagitire yicyuma irashyushye - yazungurutswe cyangwa imbeho - yazungurutswe mu cyuma cyambaye ubusa, hanyuma igasudwa cyangwa ikarohama - arc irasudira kugirango ikore umubiri uhoraho. Ikoreshwa rya anti - ruswa ryubakiye kuri uru rufatiro, ritanga irindi ruswa ryangirika kumuyoboro wibyuma ukoresheje uburyo bwo kuvura hejuru, gutwikira, cyangwa kwambara.
II. Ibisobanuro birambuye byintambwe yo gushiraho Intambwe
1. Gutegura Umuyoboro Wibanze: Gusukura no Gushiraho
Imbaraga zubusabane hagati ya anti - ruswa hamwe numuyoboro wibyuma biterwa neza nisuku nubukonje bwubuso bwibanze. Niba amavuta asigaye, ingese, cyangwa umunzani bigumye hejuru, ibikoresho birwanya - ntibishobora gukomera neza, biganisha ku bibazo byakurikiyeho nko kubyimba no gukuramo. Kubwibyo, kwitegura nintambwe yambere ikomeye muburyo bwo gushiraho.
Ibikorwa byihariye birimo:
Gukuraho ingese ya mashini: Kurasa ibisasu cyangwa ibikoresho byo kumusenyi bikoresha - umuvuduko mwinshi wicyuma cyangwa umucanga wa quartz kugirango bigire ingaruka kumuyoboro wicyuma, ukuraho igipimo kandi ugakora ubuso bumwe (mubisanzwe bisaba uburebure bwa metero 40-100μm).
Isuku yimiti: Umuti wumuti (nka acetone) cyangwa aside - ibisubizo byibanze (nka acide fosifori) bikoreshwa mugukuraho amavuta asigaye hamwe ningese ntoya, kugirango ubuso butarangwamo umwanda ugaragara.
Kuma: Umwuka ushushe cyangwa kwumisha infragre ikoreshwa mugucunga ubushuhe bwubuso bwumuyoboro wibyuma kurwego rwo hasi cyane (ubuhehere<5%) to prevent bubbles during subsequent coating.
2. Kurwanya - ruswa igaragara: kugereranya inzira nyamukuru
Ukurikije ubwoko bwa anti - ibikoresho byangirika hamwe nuburyo bukoreshwa, uburyo bwo gukora imiyoboro ya anti - ruswa ishobora kugabanywamo ibice bitatu byingenzi:
.
3PE anti - ruswa ni imiterere igizwe na "fusion bonded epoxy powder (FBE) igorofa yo hasi + yometse hagati yo hagati + polyethylene yo hanze". Ihuza cyane ifu ya epoxy hamwe nibidukikije byangiza ibidukikije birwanya polyethylene, kandi birakwiriye ahantu habi nko mumashanyarazi ya peteroli na gaze. Uburyo bwo kubumba nuburyo bukurikira:
Ipfundikizo fatizo: Gutera amashanyarazi ya porojeri ya epoxy (ubunini buke butarenze cyangwa bungana na 150 mkm) buringaniye hejuru yicyuma cya - cyavuwe hejuru yicyuma, hanyuma kigashonga hanyuma ukagikomera ku bushyuhe bwo hejuru bwa dogere 200-230 kugirango ube urwego rwinshi rwa epoxy rufite uburebure bwa metero 50-100;
Hagati yo gutwikiriye hagati: Ibifatika (nka polyethylene copolymer yahinduwe) bishyushya leta yashongeshejwe (hafi dogere 250) na extruder, hanyuma igashyirwa ku buryo buringaniye hanze ya epoxy ikoresheje ifumbire, ifite uburebure bwa metero 170-250;
Gukuramo ibice byo hanze: Hejuru - ubucucike bwa polyethylene (HDPE) nabwo bwashongeshejwe kandi bugashyirwa mu kayunguruzo kugira ngo bukore urwego rukingira hanze rufite umubyimba wa mm 1.8-3.7 (irwanya imirasire ya ultraviolet no kwangirika kwa mashini).
.
Ubu buryo bukoresha epoxy resin hamwe nigitereko cyamakara nkibikoresho nyamukuru, kandi bigakora anti - ruswa yangirika hejuru yumuyoboro wibyuma ukaraba cyangwa ugajugunya. Ibiranga ni bidahenze, ariko byumva ubushyuhe bwibidukikije byubaka (bigomba kuba birenze dogere 5) nubushuhe, kandi akenshi bikoreshwa mugutanga amazi no kuvoma imiyoboro cyangwa imishinga yigihe gito.
(3) Isima ya sima ikurikiranye - igisubizo cyinyongera kubintu bidasanzwe
Ku miyoboro yo hasi - itwara itangazamakuru ridafite - ryangiza (nk'amazi yo kunywa), uburyo bwo gutera imiti ya centrifugal burashobora gukoreshwa muguhuza neza sima ya sima (amazi - sima igereranya 0.4 - 0.5) kurukuta rwimbere rwumuyoboro wibyuma kugirango ube umurongo wa 10 - 30mm. Iyi nzira ihendutse kandi irwanya kwambara, ariko ifite imbaraga zo kurwanya ruswa.
3. Kohereza - Gutunganya no Kwipimisha: Kwemeza ubuziranenge
Nyuma yo gukora, anti - gutwika ruswa ikorerwa igenzura rikomeye:
Kwipimisha umubyimba: Gupima ubunini bwa buri cyiciro ukoresheje igipimo cya magnetiki cyangwa ultrasonic gipima (urugero, kuri 3PE anti - igifuniko cya ruswa, igipande cya epoxy kigomba kuba kinini kuruta cyangwa kingana na 80μm, kandi igipimo cya polyethylene kigomba kuba kinini kuruta cyangwa kingana na 2mm).
Kwipimisha Adhesion: Kugenzura imbaraga zubusabane hagati ya anti - kwangirika kwangirika hamwe numuyoboro wibyuma ukoresheje umusaraba - gukuramo cyangwa gukurura - uburyo (mubisanzwe bisaba Kurenza cyangwa bingana na 5MPa).
Kumenya amashanyarazi: Suzuma hejuru ya anti - ruswa yangirika hamwe na - inshuro nyinshi, hejuru ya - probe ya voltage kugirango umenye pinholes cyangwa ibyangiritse (voltage yamenetse Kurenza cyangwa bingana na 25kV).
Kugenzura Kugaragara: Kugenzura niba nta nenge zifite nk'ibibyimba, ibisebe, hamwe na sashe, byemeza neza ndetse n'ubuso.
III. Gutunganya udushya hamwe n'ibizaza
Hamwe no kwiyongera kwinganda zikenewe mu nganda, uburyo bwo gukora ruswa - imiyoboro y’ibyuma irwanya ruswa igenda itera imbere mu buryo bunoze, ikoranabuhanga ry’ubwenge, ndetse no kubungabunga ibidukikije:
Gutezimbere ibicuruzwa: Imirongo ikomeza itanga ihuza "kuzunguruka imiyoboro y'ibyuma, kwitegura, hamwe no kurwanya ruswa -," kugabanya umusaruro no kunoza umurongo;
Gutezimbere ibikoresho bishya birwanya - ruswa: Porogaramu nka nano - ifu ya epoxy yahinduwe na graphene - yongerewe polyethylene irusheho kwagura ubuzima bwa ruswa (kugeza ku myaka 50 cyangwa irenga);
Ubushakashatsi bwibikorwa byicyatsi: Kugabanya ikoreshwa ryumuti ukungahaye (urugero, gusimbuza ibishashara gakondo - bishingiye kumazi - bishingiye kuri epoxy coatings) bigabanya imyuka ihumanya ikirere.
Umwanzuro
Uburyo bwo gukora ruswa - imiyoboro idashobora kwihanganira ni indunduro yo guhuza ibikoresho siyanse, inganda zikora imashini, n’ubuhanga bw’imiti. Kuva kumiyoboro yibanze kugirango ushyire mubikorwa uburyo bwo kurwanya ruswa - ruswa, buri ntambwe isaba kugenzura byimazeyo ibipimo nibisobanuro. Hamwe niterambere ryiterambere rya tekinoloji, imiyoboro izaza - idashobora kuzuza gusa ibyangombwa byibanze byo kurwanya ruswa ahubwo izagera no ku ntera ishimishije mu kugenzura ubwenge (nko kubaka - mu byuma byangiza ruswa) no gushushanya byoroheje, bitanga inkunga yizewe mu iyubakwa ry’ibikorwa remezo ku isi.
