Monga mphamvu yofunikira pakulimbikitsa kukula kwachuma, makampani opanga zamagetsi atukuka pamlingo wochititsa chidwi. Komabe, pamene kuzindikira kwa anthu za chitetezo cha chilengedwe kukuchulukirachulukira, kupanga mapepala osindikizira osindikizira (PCBs), ulalo wofunikira pamakampani opanga zamagetsi, akukumananso ndi zovuta. Zofunikira zapamwamba zachilengedwe. Opanga PCB ochezeka ndi chilengedwe, akukhala atsogoleri amakampani pang'onopang'ono akukhala atsogoleri amakampani ndikupanga zofunikira pakukula kokhazikika kwamakampani opanga zamagetsi.

一、Kufunika kwa ma PCB opanda lead

Ma PCB achikhalidwe okhala ndi mtovu amatulutsa zinthu zovulaza monga mtovu panthawi yopanga ndikugwiritsa ntchito, zomwe zingawononge kwambiri chilengedwe komanso thanzi la anthu. Mtovu umatha kulowa m'chilengedwe kudzera mumlengalenga, madzi ndi nthaka, kuwunjikana m'zamoyo, ndikusokoneza chilengedwe. Nthawi yomweyo, kukhudzana kwa nthawi yayitali ndi zinthu zokhala ndi mtovu kungayambitsenso matenda mu dongosolo lamanjenje lamunthu, dongosolo la magazi ndi zina. Chifukwa chake, kulimbikitsa PCB yopanda kutsogolera kwakhala chisankho chosapeŵeka kwa makampani opanga zamagetsi kuti akwaniritse chitukuko chobiriwira.

二、 Ubwino wa opanga ma PCB ochezeka ndi chilengedwe

Zopanga zamakono

Opanga PCB ochezeka ndi chilengedwe, odzipereka ku luso laukadaulo ndipo nthawi zonse amapanga njira zatsopano zopangira ndi zida kuti zitsimikizire mtundu wazinthu ndi magwiridwe antchito. Pogwiritsa ntchito luso lapamwamba lazitsulo lopanda kutsogolo, zipangizo zowononga chilengedwe, ndi machitidwe okhwima owongolera khalidwe, opangawa amatha kupanga ma PCB apamwamba kwambiri omwe amakwaniritsa miyezo yapadziko lonse ya chilengedwe.

Chidziwitso cha chilengedwe

Monga ochirikiza chitetezo cha chilengedwe, opanga ma PCB opanda kutsogolera amaphatikiza malingaliro oteteza chilengedwe panthawi yonse yopangira. Kuchokera pakusankha zida zopangira mpaka kukhathamiritsa kwa njira zopangira mpaka kutaya zinyalala, zofunikira zoteteza chilengedwe zimatsatiridwa mosamalitsa. Amalimbikitsa mwachangu njira zopangira zobiriwira, amachepetsa kugwiritsa ntchito mphamvu ndi mpweya woipa, komanso amathandizira kuteteza chilengedwe.

Chitsimikizo chadongosolo

Opanga PCB osatsogolera zachilengedwe amakhala ndi machitidwe okhwima owonetsetsa kuti zinthu zili bwino komanso zodalirika. Amagwiritsa ntchito zida zoyezera zapamwamba komanso akatswiri owunikira akatswiri kuti ayesetse mosamalitsa pa PCB iliyonse kuti awonetsetse kuti zinthuzo zikukwaniritsa miyezo yapadziko lonse lapansi komanso zofunikira zamakasitomala.

Ubwino wautumiki

Kuti akwaniritse zosowa za makasitomala, opanga PCB okonda zachilengedwe, omwe alibe kutsogolera, nthawi zambiri amapereka mautumiki osiyanasiyana. Sikuti iwo angasinthe makonda a PCBs osiyanasiyana malinga ndi zofuna za makasitomala, amathanso kupereka chithandizo chaukadaulo komanso ntchito yogulitsa pambuyo pogulitsa kuthandiza makasitomala kuthana ndi mavuto omwe amakumana nawo pakugwiritsa ntchito.

三、Kuyembekeza kwachitukuko kwa opanga PCB ochezeka ndi chilengedwe

M'tsogolomu, kutsindika kwapadziko lonse pachitetezo cha chilengedwe kudzapitirira kuwonjezeka, zomwe zidzachititsanso kuti kufunikira kwa msika kwa ma PCB opanda kutsogolera kupitirire kukula. Opanga PCB opanda kutsogolera opanda chilengedwe adzabweretsa malo okulirapo. Panthawi imodzimodziyo, idzalimbikitsanso opanga kuti apitirize kuonjezera luso lamakono, kusintha khalidwe lazogulitsa ndi ntchito, ndipo panthawi imodzimodziyo azikulitsa msika kuti apatse makasitomala ambiri zinthu za PCB zamtundu wapamwamba kwambiri zomwe zimagwirizana ndi chilengedwe.

Monga mpainiya wobiriwira mumakampani opanga zamagetsi, opanga ma PCB osatsogolera zachilengedwe akutsogolera makampani opanga zamagetsi ku tsogolo lobiriwira komanso lokhazikika ndi luso lawo laukadaulo, kuzindikira kwa chilengedwe, kutsimikizira kwabwino komanso ubwino wautumiki. Ndi khama lawo, makampani opanga zamagetsi adzapeza chitukuko chochuluka pamene akuteteza chilengedwe.
