Chiedza-kurapa prepreg haingove nekushanda kwakanaka kwekuvaka, asi zvakare ine yakanaka corrosion kuramba kune general acids, alkalis, munyu uye organic zvinonyungudutsa, pamwe nesimba rakanaka remuchina mushure mekurapa, senge FRP yechinyakare. Aya akanakisa zvivakwa anoita prepregs anorapika akakodzera kumakemikari, matangi ekuchengetera peturu, pamusoro-pasi uye pasi pevhu mapaipi, nezvimwewo, kugadzira anti-corrosion midziyo ine mashandiro akanaka.
1. Kushandiswa kwe-anti-corrosion lining yetangi yekuchengetedza mafuta
Kuenzaniswa nekugadzirisa maitiro ekubatanidza kuumba lining, nokuti chiedza-chinoporesa prepreg inogona kugadzirirwa kuva mapepa kana mipumburu, uye kune mafirimu epurasitiki pamusoro pepamusoro nepamusoro pepamusoro, iyo inonyungudutsa inopisa panguva yekuvaka iduku, iyo inovandudza zvikuru nzvimbo yekuvaka nekuchengeteka. sex. Iyo isina kupora mwenje-inorapa prepreg yakapfava uye inogona kutemwa kana kucheka zvinoenderana nezvinodiwa zvepurojekiti yobva yaiswa zvakananga. Inorapwa neUV mwenje. Nguva yekubika ndeye 10 kusvika kumaminitsi makumi maviri chete. Haina kukanganiswa nemhoteredzo uye inogona kushandiswa gore rose. Kuvaka, kunogona kushandiswa pakarepo mushure mekurapa, kudzikisa zvakanyanya nguva yekuvaka uye mutengo wevashandi.
PaPetroChina Chongming No. 3 gas station, light-cured prepreg yakagadzirwa neMERICAN 9505 yakashandiswa kugadzirisa tambo yetangi rekuchengetedza mafuta. Mamiriro ekuvaka akakodzera anoratidzwa mumufananidzo uri pasi apa. Iyo yakaoma inogona kusvika makumi matanhatu, uye ine yakanaka corrosion resistance.
2. Anti-corrosion application in directional drilling pombi
Directional drilling inzira yekuvaka pombi muinjiniya tekinoroji indasitiri. Inoshandiswa zvakanyanya mukuvaka oiri, gasi rechisikigo uye mamwe mapaipi emanisipala. Nzira yekudzivirira sei anti-corrosion yekunze sheath panguva yekuchera pombi inotungamira yakagara iri dambudziko rakaoma mumunda wekuvaka pombi. . Mazhinji emapombi anochinjika anoshandiswa mukutungamira kudhiraivha kuyambuka, uye kuoma kweiyo anti-corrosion layer pamusoro pemuviri wepombi haina kukwana. Munguva yekukweva, iyo anti-corrosion layer inowanzo tsemuka kana mupendero wechinhu chinobatirira chakamonywa kana kutyoka, izvo zvinokanganisa anti-corrosion maitiro uye zvakanyanya kuisa mungozi kuchengetedzeka kwepombi. Tichifunga nezvematambudziko ari pamusoro apa, prepreg yakarapwa chiedza inogona kushandiswa sechidziviriro chechikamu chekunze chepombi. Hunhu hwayo hunonyanya kuomarara, kukwenya kuramba uye friction resistance, iyo inogona kunyatso chengetedza anti-corrosion layer.
Kuenzanisa kwechiedza chekudzivirira sleeve pamberi uye mushure mekushandiswa kwepaipi yekuchera inotungamira inoratidzwa mumufananidzo unotevera:
Zvinogona kuoneka zvakajeka kubva pakuenzanisa kuti chiedza-chakaporeswa prepreg layer ine yakanaka kudzivirira papombi uye inovandudza anti-corrosion kuita kwepombi.
3. Anti-corrosion kushandiswa kwemafuta uye gasi rekuchengetedza tangi padenga
Mazhinji emafuta uye gasi ekuchengetedza matangi matangi esimbi esimbi. Nemhaka yokuti oiri negasi zvinowanzova nezvinhu zvinoparadza, kukora kwematangi esimbi kwakakomba zvikuru. Semuenzaniso, pasi pekuita kwekushisa kwepamusoro mutangi, magasi anokuvadza akadai seokisijeni yakanyungudutswa, hydrogen sulfide uye kabhoni dhaibhoni inoputika uye inokonzera kusimba kwakasimba pamusoro petangi, zvichikonzera kukuvadza kwakakomba kumusoro kwetangi, izvo zvisingangokonzeresa kurasikirwa kukuru kwemafuta uye gasi, asiwo kunowedzera kuchengetedzwa. ngozi yakavanzwa. Nekushandisa kwakachengeteka kwemafuta uye gasi ekuchengetedza matangi, kugadzirisa kwenzvimbo kana kutsiviwa kwepamusoro petangi kunodiwa kazhinji. Nzira yechinyakare yekugadzirisa denga retangi ndeyekutsiva simbi tangi padenga resimbi ndiro, inoda kuti tangi imiswe, kucheneswa, nzvimbo yekuvaka kuti igadzire matanho ekuchengetedza, uye dhipatimendi rekuchengetedza kubvumidza zvidimbu ne layer. Nguva yekuvaka yakareba uye mutengo wekugadzirisa wakakwirira. Zvisinei, uchishandisa chiedza-kuporesa prepreg, tangi iripo inoshandiswa se template, uye yakagadzirwa uye yakachekwa panzvimbo, uye inosungirirwa neyokutanga tangi yesimbi kuti iite yakazara. Pamusoro pekuchengetedza simba rekutanga tangi yepamusoro, Simba remusanganiswa wepamusoro rinowedzerwa uye rinogona kushandiswa sechigadziro chitsva chekugadzirisa denga remafuta uye gasi rekuchengetedza matangi.
Mukuwedzera kune minda yakataurwa pamusoro-ye-anti-corrosion, mapreg-curing prepregs anogona kushandiswawo muminda yekudzivirira-corrosion senge pool linings munzvimbo dzepasi pevhu, pombi dzepasi pevhu, matangi ekuchengetera mumarara emarara, zvikepe zvezvikepe, uye kugadzirisa kwesimba remagetsi. Parizvino, mazhinji emwenje-anorapa prepreg mapepa pamusika zvigadzirwa zvinounzwa kunze kwenyika, uye mutengo wakakwirisa, izvo zvinoganhurira kushandiswa kwavo. Nekudaro, nerutsigiro rwenyika, kutariswa kwemusika, uye kuwedzera kwekudyara kwekutsvaga nekusimudzira zviwanikwa, kuchave nekuwanda uye kwakasiyana marudzi epamba-akaporeswa prepreg mapepa anoshandiswa munzvimbo dzakasiyana.
