Chii goridhe rinoshandiswa pcb kugadzira?

Mabhizinesi nevatengi vanovimba nemidziyo yemagetsi kweanenge ese maficha ehupenyu hwavo hwezuva nezuva.Mota dzakazara yakadhindwa redunhu bhodhi (PCB) yezvinhu zvese kubva kumwenje uye varaidzo kusvika kuma sensors ayo anodzora maitiro eakakomba mashandiro emagetsi. Makomputa, mapiritsi, mafoni emafoni uye kunyange matoyi mazhinji anonakidzwa nevana anoshandisa zvigadzirwa zvemagetsi uye PCB pamabasa avo akaomarara.

Vanogadzira PCB vemazuva ano vanosangana nedambudziko rekugadzira mabhodhi akavimbika anoita mabasa anowedzera kuomarara achidzora mutengo uye achideredza saizi. Izvi zvinonyanya kukosha muma smartphones, drones uye mamwe mashandisiro, uko huremu hwakakosha kutariswa muPCB hunhu.

Ndarama chinhu chakakosha mukugadzirwa kwePBB, uye chengeta “zvigunwe” pane akawanda maPCB kuratidza, kusanganisira esimbi macontact akagadzirwa negoridhe. Iyi minwe inowanzo kuve yakawanda multilayer simbi uye inogona kusanganisira chinhu chakaputirwa neyekupedzisira hutete hwegoridhe, senge tini, lead, cobalt kana nickel. Aya macustomer egoridhe akakosha kune mashandiro ePCB inokonzeresa, kumisikidza kubatana nechigadzirwa chine bhodhi.

Nei goridhe?

Hunhu hunoti goridhe rinoita kuti ive sarudzo yakanakisa yekugadzira PCB. Ndarama-yakafukidzwa pamupendero macomputer inopa akaenzana ekumusoro ekupedzisa ezvishandiso zvinove zvakakwirira kupfeka, senge ndiro yekuisa yekumucheto mapoinzi. Iyo yakaoma yegoridhe pamusoro ine yakatsiga yepamusoro inodzivisa kupfeka inokonzerwa neichi chiitiko chakadzokororwa.

Nehunhu hwayo chaiyo, goridhe rakaringana kune zvemagetsi zvinoshandiswa.

Zviri nyore kuumba uye kushanda pazvibatanidza, mawaya uye kuendesa kutaurirana

Ndarama inoitisa magetsi zvakanyatsonaka (chinodikanwa pachena chePCB kunyorera)

Inogona kutakura hushoma hwazvino, izvo zvakakosha kune zvemagetsi zvemazuva ano.

Zvimwe simbi dzinogona kuvezwa negoridhe, senge nickel kana cobalt

Iyo haina discoloror kana corrode, ichiita kuti ive yakavimbika yekubatanidza svikiro

Kunyungudutsa uye kudzokororazve goridhe chiitiko chiri nyore

Chete sirivheri nemhangura zvinopa yakakwira magetsi kuitisa, asi yega yega inokasira kuita ngura, ichigadzira zvazvino kuramba

Kunyange dzakaonda goridhe kunyorera zvinopa yakavimbika uye yakagadzikana mitezo ine yakaderera kuramba

Goridhe kubatanidza inogona kumira yakasimba tembiricha

Ukobvu kusiyanisa NIS inogona kushandiswa kuzadzikisa zvinodikanwa zvezvimwe zvikumbiro

Anenge zvese zvigadzirwa zvemagetsi zvine imwe nhanho yegoridhe, inosanganisira maTV, mafoni, makomputa, zvishandiso zveGPS, uye nehunyanzvi hwekupfeka. Makomputa mashandisirwo echisikirwo ePCBS ane goridhe uye zvimwe zvinhu zvegoridhe, nekuda kwekuda kwekuvimbika, kumhanya-mhanya kutapurirana kwemasaini edhijitari ayo akakodzera zvirinani kune goridhe kupfuura chero imwe simbi.

Ndarama haina kuenzanisirwa kunyorera kusanganisira yakaderera magetsi uye yakaderera kuramba zvinodiwa, ichiita sarudzo yakanaka yePCB yekutaurirana uye zvimwe zvigadzirwa zvemagetsi. Iko kushandiswa kwegoridhe mumidziyo yemagetsi iko zvino kwakapfuura kudyiwa kwesimbi yakakosha muzvishongo.

Imwe mupiro goridhe yaita kune tekinoroji indasitiri yemuchadenga. Nekuda kweiyo yakareba tarisiro yehupenyu uye kuvimbika kweyekubatana kwegoridhe uye PCBS yakabatanidzwa muchadenga uye satellites, goridhe yaive sarudzo yechisikigo yezvinhu zvakakosha.

Dzimwe nyaya dzinoda kutariswa muPCB

Ehe, pane zvinokanganisa kushandisa goridhe muPCBS:

Mutengo – Ndarama isimbi yakakosha ine zviwanikwa zvishoma, ichiita chinhu chinodhura chinoshandiswa mumamirioni emidziyo yemagetsi.

Resource kurasikirwa – mumwe muenzaniso iko kushandiswa kwegoridhe mune zvemazuva ano zvishandiso senge mafoni. Mazhinji mafoni emafoni haana kudzokororwazve, uye nekuregeredzwa kuraswa kunogona kurasikirwa zvachose nekaundi goridhe. Kunyangwe hazvo huwandu hwacho huri hushoma, huwandu hwemidziyo yemarara hwakakura uye hunogona kuburitsa yakawandisa goridhe risina kucherwa.

Kuzvipfekedza pachako kunogona kupfeka uye kuzvizora pasi pekudzokorora kana kumanikidza kumisikidza / kutsvedza mamiriro. Izvi zvinoita kuti zvinyatso kushanda kushandisa zvakaoma zvinhu zvekushandisa pane inoenderana substrates. Kumwe kufunga kwekushandisa kwePBB ndiko kusanganisa goridhe neimwe simbi, senge nickel kana cobalt, kugadzira alloy inonzi “yakaoma goridhe”.

Iyo US Environmental Protection Agency (EPA) inoshuma kuti e-marara iri kukura nekukurumidza kupfuura chero zvimwe zvigadzirwa zvemarara. Izvi zvinosanganisira kwete chete kurasikirwa kwegoridhe, asiwo zvimwe zvakakosha simbi uye pamwe zvine chepfu zvinhu.

Vagadziri vePBB vanofanirwa kuyera kushandiswa kwegoridhe muPBB yekugadzira: kushandisa yakanyanya kuonda simbi inogona kudzikisira kana kukanganisa bhodhi. Kushandisa kuwedzera kwehuremu kunopambadza uye kunodhura kugadzira.

Parizvino, vagadziri vePCB vane sarudzo shoma kana dzimwe nzira dzekurarama zvinoenderana nehunyanzvi uye hunhu hwegoridhe kana alloys yegoridhe. Kunyangwe iine kukosha kwayo kwepamusoro, iyi simbi yakakosha pasina mubvunzo zvinhu zvekusarudza kwekuvakwa kwePCB.
