Unoziva here kuti ndedzipi nzira dzekurapa dzesimbi ine ngura ndiro?

Simbi ndiroiri zvakare nyore zvakanyanya kuita ngura mushure menguva yakareba, kwete kungokanganisa kunaka, asiwo inokanganisa mutengo wesimbi ndiro. Kunyanya kuita laser paplate pamusoro pezvinodiwa zvakaomesesa, chero bedzi paine ngura mavara asingakwanise kugadzirwa, iyo nyaya yemapanga akatyoka, iyo ndiro yepasi haina kutsetseka nyore kurova laser yekucheka musoro. Saka chii chatinofanira kuita nendiro yesimbi ine ngura?

1. Primitive manual descaling
Iyo inonzi primitive descaling ndeyekukwereta manpower kuti udzikise nemaoko. Iyi inzira yakareba uye yakaoma. Kunyangwe iyo nzira inogona kushandiswa mufoshoro, nyundo yemaoko uye mamwe maturusi, asi mhedzisiro yekubvisa ngura haina kunaka. Kunze kwekunge nzvimbo diki yekubvisa ngura uye pasina dzimwe sarudzo dzekushandisa nzira iyi, dzimwe nyaya hadzikurudzirwe.

2. Simba rekushandisa ngura kubvisa
Power tool descaling zvinoreva kushandiswa kwemhepo yakadzvanyirirwa kana kushandisa nzira dzemagetsi dzinofambiswa nemagetsi, kuitira kuti chinodzikisira chibudise denderedzwa kana kudzoreredza kufamba. Paunenge uchisangana nepamusoro peplate yesimbi, shandisa kukwenya kwayo uye kukanganisa kubvisa ngura, ganda rine oxidized nezvimwe zvakadaro. Iko kudzika kwekuita uye kunaka kwechishandiso chemagetsi ndiyo inowanzoshandiswa nzira yekudzikisa mumapurojekiti ekupenda parizvino.

Kana ukasangana nekunaya, kuine chando, mhute kana kunyorova mamiriro ekunze, nzvimbo yesimbi inofanirwa kuvharwa neprimer kudzivirira ngura kudzoka. Kana ngura yakadzoka isati yatanga kushandiswa, ngura inofanira kubviswa zvakare uye primer inofanira kushandiswa munguva.
3. Kubvisa ngura nekuputika
Jet descaling inoreva kushandiswa kweiyo impeller yepakati yemuchina wejeti kufemesa iyo abrasive uye muromo weblade kuburitsa abrasive kuti iwane yakakwirira-kumhanya kukanganisa uye kuwedzera kukweshera kuita kudzika kwesimbi ndiro.

4. Pfapfaidza descaling
Kupfapfaidza descaling nzira ndiko kushandiswa kwemhepo yakadzvanywa ichave inoputika pakumhanya kukuru kutenderera yakapfapfaidza kumusoro kwesimbi ndiro, uye kuburikidza neabrasive kukanganisa uye friction kubvisa oxide ganda, ngura uye tsvina, kuitira kuti pamusoro pesimbi ndiro. kuti uwane imwe dhigirii yehukasha, inobatsira pakusimudzira kunamatira kwefirimu repende.

5. Chemical descaling
Chemical descaling inogona zvakare kunzi pickling descaling. Kuburikidza nekushandisa pickling mhinduro muasidhi uye simbi oxides reaction, nyungudutsa simbi oxides, kuitira kubvisa simbi pamusoro oxides uye ngura.

Kune nzira mbiri dzakajairwa dzekunhonga: dzakajairika pickling uye yakazara pickling. Mushure mekunhonga, zviri nyore kuve oxidized nemhepo, uye inofanirwa kupfuudzwa kuti ivandudze kushora kwayo.

Passivation treatment inoreva ndiro yesimbi mushure mekutora, kuitira kuti iwedzere nguva yayo kudzokera kune ngura, nzira inoshandiswa kuitira kuumba firimu rinodzivirira pamusoro pesimbi, kuitira kuti ivandudze kushanda kwayo.

Maererano nemamiriro chaiwo ekuvaka, nzira dzakasiyana dzekurapa dzinogona kushandiswa. Kazhinji ndiro yesimbi inofanira kugezwa nemvura inopisa kuti isarerekera pakarepo mushure mekunhonga, yobva yapfuudzwa. Uye zvakare, simbi inogona zvakare kucheneswa nemvura nekukurumidza mushure mekunhonga, uye wobva wawedzera 5% sodium carbonate mhinduro yekumisa iyo alkaline mhinduro nemvura, uye pakupedzisira passivation kurapwa.

6. Kupisa kwemoto
Kudzika moto kwendiro yesimbi kunoreva kushandiswa kwesimbi simbi bhurashi kubvisa ngura inonamirwa pamusoro pendiro yesimbi mushure mekupisa mushure mekupisa kwemoto. Usati wabvisa ngura kubva pamusoro pendiro yesimbi, ngura yakakora yakasungirirwa pamusoro pendiro yesimbi inofanira kubviswa isati yabvisa ngura nekupisa kwemoto.
