Kutaura nezvemapombi emakemikari process, anowedzera uye anoshandiswa zvakanyanya mukugadzirwa kwemaindasitiri, kunyanya mumunda wemakemikari, corrosion-resistant chemical process pumps ari kuwedzera kuita basa rakakosha. Mumamiriro ezvinhu akajairwa, nekuda kweiyo nharaunda umo makemikari process pombi anoshandiswa, anowanzo gadzirwa nesimbi kana fluoroF46. Kune simbi dzakajairwa, chimiro chadzo chinokonzeresa kuita ngura, uye nharaunda yekunze senge tembiricha, hunyoro uye mweya Inotungamira kune simbi corrosion, saka zvinhu zvedu zvakajairika zvemapombi anodzivirira makemikari process isimbi isina tsvina uye fluoroplastic F46.

Iyo yepakati inokodzera makemikari process pombi inonyanya kuodza, uye pachikamu chekuora, pane kazhinji nzira mbiri dzekuisa.

Iyo meshini yakakamurwa, uye imwe yacho inorongwa maererano nechikonzero uye kutaridzika kwekuora. Zvinoenderana nemaitiro ekuora, inogona kukamurwa kuita electrochemical corrosion uye kemikari corrosion. Electrochemical corrosion inonyanya kureva chiitiko chekuora kunokonzerwa neelectrode reaction pamusoro pechinhu chesimbi mushure mekunge chasangana nemhinduro ye electrolyte. Kuita uku kunowanzoita redox reaction, uye zvinhu zvikuru hunyoro uye tembiricha yezvakatipoteredza; Kemikari corrosion (Chemical corrosion) zvinoreva kemikari ine simba iri pakati pesimbi nepakati nepakati, izvo zvinoita kuti simbi ikuvare kusvika kumwero wakati. Zvikonzero zvikuru zvekuora uku kupisa kwakanyanya uye nzvimbo yakaoma. Zvinoenderana nechitarisiko uye zvinokonzeresa ngura, inogona kupatsanurwa kuita peeling corrosion, maindasitiri emuchadenga corrosion, yakanyanya tembiricha oxidation corrosion uye marine atmospheric corrosion.

Munharaunda ine kusvibiswa kwakakomba kwemaindasitiri, nekuti kune zvimwe zvinhu zvinoputika senge sulfide, kabhoni dhaidhikisi uye hydroxide mumhepo, uye zvakare ine imwe guruva remaindasitiri, aya ma media ari nyore kukonzera ngura. Kana midhiya iyi iri munzvimbo ine mwando, gasi reasidhi rinosangana nemvura kuumba inorganic acids. Aya maasidhi ane corrosive properties ane simba, saka anozoita kuti aite ngura. Munharaunda yemhepo yeindasitiri, zvishandiso zvinokonzerwa neyakasanganiswa mhedzisiro ye electrochemical corrosion uye yakananga kemikari corrosion. The musimboti ngura zvose chaizvoizvo oxidation muitiro umo simbi zvinhu anorasikirwa maerekitironi kuumba ayoni. Musiyano mukuru pakati pe electrochemical corrosion uye industrial atmospheric corrosion ndiyo nzvimbo dzakasiyana dzavanoitika.

Kuora kwemidziyo kunoenderana zvakanyanya nezvinhu zvemidziyo. Muchisarudzo chekugadzirwa kwezvinhu zvemakemikari, tinofanira kutarisa pakuitika kwekuora, kuchenjerera kusarudzwa kwakanaka kwezvinhu, uye kunyatsofunga nezvezvinhu zvepakati, tembiricha yezvakatipoteredza uye kushandiswa kwekushanda, nezvimwewo Maererano ne indasitiri yemakemikari Zvinodiwa zvezvinhu zvakasvibiswa uye chimiro uye mhando yezvigadzirwa zvekugadzira. Dhizaini yechimiro inofanirwa kutarisisa pane zvinodiwa zvekugadzira uye kushushikana hunhu mukugadzira uye kushanda kwemakemikari emidziyo, uye zvinotevera zvinhu zvinofanirwa kutariswa mukugadzira: chekutanga, izvo zvinodikanwa zvechigadzirwa zvinofanirwa kuenderana nekuora. kupikisa zvinodiwa zvekugadzirwa kwezvinhu zvemakemikari; chechipiri Zvakakosha kutarisisa kugadzikana kwekushanda uye kutsvedzerera kwemakemikari emidziyo, kudzivirira kumiswa kwezvinosvibisa midhiya, kugoverwa kusina kuenzana kwekupisa kwekupisa, kunyungudutswa kweutsi uye kuunganidzwa kwezvigadzirwa zvecorrosion; pakupedzisira, zvinokosha kuteerera kudzivirira kunze masimba kudzivirira Kuneta ngura kunokonzerwa alternating kushushikana.
