Copper inhibitor kana copper deactivator ndeye inoshanda yekuwedzera inoshandiswa mu polymer zvinhu zvakaita semapurasitiki nerabha. Basa rayo guru ndere kuvharidzira kuchembera kunokonzera mhedzisiro yemhangura kana mhangura ion pane zvinhu, kudzivirira kuparara kwezvinhu, kubuda kwemavara, kana kuparara kwemidziyo kunokonzerwa nekusangana nemhangura. Izvo zvinonyanya kukosha muminda senge waya conduit, tambo sheath, zvemagetsi kurongedza zvinhu, nezvimwe.
Mhangura nemaaloyi ayo (akadai sewaya) anoshandiswa zvakanyanya mukufambiswa kwemagetsi, asi kana mhangura yasangana zvakananga nezvimwe zvinhu zvepolymer (sePVC, polyethylene), inogona kukonzera matambudziko anotevera:
Catalytic oxidation:
Cu2+ yakasimba oxidation catalyst inomhanyisa iyo oxidative kutsemuka kwepolymer molecular cheni, kunyanya mukupisa kwakanyanya uye hunyoro nharaunda.
Acid corrosion:
Mune halogenated zvinhu zvakadai sePVC, mhangura inogona kuita neHCl yakaora kuti ibudise copper chloride (CuCl2), ichiwedzera kukurumidza kuparara kwezvinhu (self catalytic effect).
Kuora kwechitarisiko:
Kutama kwecopper ions kunogona kuita kuti mavara egirinhi kana madema (copper rust) aonekwe pamusoro pezvinhu, zvichikanganisa kutaridzika kwayo.
Iyo nzira yekuita ye deactivator
Deactivators inodzvinyirira kukanganisa kwemhangura kuburikidza nenzira dzinotevera:
Chelated copper ions:
Yakasanganiswa neCu2 + yemahara, macomplexes akatsiga anoumbwa kuti avhare basa ravo recatalytic (senge benzotriazole compounds).
Passivation of copper surface:
Gadzira firimu rinodzivirira pamusoro pemhangura kudzivirira kusunungurwa kweoni yemhangura (yakadai seorganic phosphorus compounds).
Neutralizing acidic zvinhu:
MuPVC, mamwe madhiraivha anogona kumisa HCl inogadzirwa nekuora, kuderedza kukora kwemhangura (senge lead salt stabilizers inewo mhangura inodzivirira basa).
Copper Deactivators imhando ye "Invisible Guardian" mune zvepolymer zvinhu zvinowedzera zvakanyanya hupenyu hwesevhisi yezvigadzirwa zvakaita sewaya sheathes nekudzikisira chiitiko chinokonzeresa chemhangura. Iyo yakakosha yetekinoroji yayo iri mune chaiyo makemikari chelation uye yepasi passivation, uku ichienzanisa hushamwari kwezvakatipoteredza uye mutengo-kushanda. Mukugadzirwa kwewaya casing, iyo coordinative formula yedeactivators, moto retardantuye zvimwe zvinowedzera ndiyo kiyi yekuvimbisa kuvimbika kwenguva refu kwezvinhu.
