Kune mavara madema pagirazi yekugezera muimba yekugezera, iyo inongoratidzira chiso kana ichitarisa mugirazi, iyo inobata zvikuru kushandiswa kwezuva nezuva.Magirazi haawane mavara, saka nei achiwana mavara?
Kutaura zvazviri, mamiriro ezvinhu akadaro haawanzoitiki.Iyo yakajeka uye yakanaka girazi yekugezera iri pasi pemhepo yekugezera kwenguva yakareba, uye mupendero wegirazi uchaita zvishoma nezvishoma dema uye kunyange zvishoma nezvishoma uchipararira pakati pegirazi.Chikonzero ndechekuti pamusoro pegirazi rinowanzo gadzirwa ne electroless sirivheri plating, uchishandisa sirivheri nitrate sechinhu chikuru mbishi.
Pane mamiriro maviri ekuitika kwemavara matema.Imwe ndeyokuti munzvimbo ine hunyoro, pendi yekudzivirira uye sirivheri yeplating layer iri kuseri kwegirazi inobvisa, uye girazi harina rinoratidzira.Chechipiri ndechekuti munzvimbo ine hunyoro, sirivheri-yakapfatwa pamusoro pepamusoro inoiswa oxidized mu silver oxide nemhepo, uye sirivheri oxide pachayo chinhu chitema, chinoita kuti girazi riite dema.
Magirazi ekugezera akachekwa ese, uye mipendero yegirazi inocheneswa nyore nyore nehunyoro.Kuora uku kunowanzopararira kubva kumucheto kusvika pakati, saka kumucheto kwegirazi kunofanira kuchengetedzwa.Shandisa girazi glue kana edge banding kuti uname kumucheto kwegirazi.Mukuwedzera, zvakanakisisa kuti usatsamira pamadziro paunenge uchiisa girazi, uchisiya mamwe mapeji ekufambisa kubuda kwemhute uye mhute yemvura.
Kana girazi rashanduka dema kana kuva nemakwapa, hapana nzira yekurideredza kunze kwekuritsiva negirazi idzva.Naizvozvo, kushandisa zvine musoro uye kugadzirisa pamazuva evhiki kunova kwakakosha kwazvo;
Cherechedzai!
1. Usashandise asidhi yakasimba uye alkali uye zvimwe zvinosvibisa zvigadziriso zvekuchenesa girazi repamusoro, izvo zvingaita nyore kukanganisa kugirazi;
2. Chiratidzo chegirazi chinofanira kupukutwa nemucheka wakapfava wakaoma kana donje kuti udzivise girazi repamusoro kubva pakukweshwa;
3. Usapukuta zvakananga pamusoro pegirazi nemucheka wakanyorova, sezvo kuita kudaro kunogona kuita kuti unyoro hupinde mugirazi, huchikanganisa kushanda uye hupenyu hwegirazi;
4. Shandisa sipo pamusoro pegirazi uye uipuse nemucheka munyoro, kuitira kuti mhute yemvura isanamatira pamusoro pegirazi.
