Ukuqina Kwethusi ku-PCB: Ukuqonda Ukuqina Kwe-Ounce E-1

Uma usembonini yokukhiqiza yebhodi lesekethe ephrintiwe (PCB), ungase uhlangane nombuzo kaningi: "Ingabe ugqinsi luka-1 ounce lwethusi ku-PCB?" Lona umbuzo ovumelekile ngoba ubukhulu bekhopha ku-PCB bunemithelela ebalulekile ekusebenzeni kwayo kanye nokusebenza Sekukonke kudlala indima ebalulekile.Kulokhu okuthunyelwe kwebhulogi, sizocubungula isihloko futhi sikunikeze yonke imininingwane edingekayo mayelana nogqinsi lwethusi oluyi-1 oz ku-PCB.

Ngaphambi kokuthi singene kokucacisiwe, ake sibuyele emuva futhi siqonde umqondo wesisindo sethusi ku-PCB.Uma sikhuluma ngesisindo sethusi, sibhekise kugqinsi longqimba lwethusi olusetshenziswa ukwenza i-PCB. Iyunithi yokulinganisa yesisindo sethusi ngama-ounces (oz). Kumele kuqashelwe ukuthi ubukhulu bethusi bulingana nesisindo salo, okungukuthi, njengoba isisindo sanda, ukushuba kuzokwanda.

Manje ake sigxile ku-ounce eyodwa yethusi. Igama elithi “iounce yethusi elingu-1” libhekisela kumitha-skwele ngayinye yethusi elisetshenziswa ekwenziweni kwe-PCB.Kalula nje, ubukhulu be-ounce yethusi elingu-1 ku-PCB bulinganiselwa ku-1.37 mils noma amayintshi angu-0.00137, okulingana nama-microns angu-34.8. Lesi silinganiso siyindinganiso yemboni futhi sisetshenziswa ezinhlotsheni eziningi zokusebenza.

Ugqinsi lwe-ounce yethusi elingu-1 ku-PCB lubhekwa njengelifanele izinhlelo zokusebenza eziningi ezidinga amandla amaphakathi kanye nokusebenza kwesignali.Ifinyelela ukulingana okuphelele phakathi kokusebenza nokusebenza kahle kwezindleko. Kodwa-ke, kufanele kukhunjulwe ukuthi izinhlelo zokusebenza ezahlukene zingadinga izisindo zethusi ezahlukene. Nakuba i-copper engu-1 oz inemisebenzi eminingi, ezinye izinketho ezifana no-2 oz noma 0.5 oz zethusi zingase zifaneleke kangcono izimo ezithile.

Manje njengoba sesixoxile ngogqinsi lwe-ounce yethusi elingu-1, ake sihlole ezinye zezinto ezibalulekile ezinquma ukukhethwa kwesisindo sethusi ku-PCB.Okokuqala, kuya ngezidingo zamandla wesifunda. Uma isifunda sidinga ukuthwala imisinga ephezulu, kungase kudingeke ungqimba olukhulu lwethusi ukuze kuqinisekiswe ukuhanjiswa okwanele nokuvimbela ukukhiqizwa kokushisa okukhulu. Ngakolunye uhlangothi, izinhlelo zokusebenza zamandla aphansi zingasebenzisa izendlalelo zethusi ezincanyana.

Okwesibili, imvamisa yezimpawu ezithwalwa yi-PCB nayo ithinta ukukhethwa kwesisindo sethusi.Amafrikhwensi aphezulu adinga izendlalelo zethusi ezijiyile ukuze kuncishiswe ukulahleka kwesignali nokugcina ubuqotho besignali. Lokhu kubaluleke kakhulu kumasekhethi edijithali anesivinini esikhulu kanye nezinhlelo zokusebenza zamafrikhwensi omsakazo.

Ukwengeza, amandla emishini nokuqina kwe-PCB kuthintwa isisindo sethusi.Izendlalelo zethusi eziwugqinsi zinikeza ukwesekwa okungcono futhi zinciphisa ingozi yokulimala ngesikhathi sokuphatha, ukuhlanganisa nokusebenza.

Sekukonke, ubukhulu be-ounce yethusi elingu-1 ku-PCB bucishe bube ngu-1.37 mils noma amayintshi angu-0.00137.Kuyisilinganiso esijwayelekile esisetshenziswa kabanzi embonini ngezinhlelo zokusebenza ezahlukahlukene. Kodwa-ke, kubalulekile ukucabangela izidingo ezithile ze-PCB kanye nemvelo yesifunda ukuze kunqunywe isisindo sethusi esifanele kakhulu. Izinto ezifana nezidingo zamandla, imvamisa yesignali, namandla okusebenza konke kuyavela uma kuthathwa lesi sinqumo.

Ngokufigqiwe, ukwazi ubukhulu be-ounce yethusi elingu-1 ku-PCB kubalulekile kunoma ubani obambe iqhaza embonini yokukhiqiza ye-PCB.Isiza ukwenza izinqumo ezinolwazi mayelana nenqubo yokuklama neyokukhiqiza, iqinisekisa ukusebenza kahle kwesekethe. Ngakho-ke, ngesikhathi esilandelayo lapho othile ekubuza ukuthi "Ingakanani iounce yethusi eli-1 ku-PCB?" unalo lonke ulwazi oludingayo ukuze ubanike impendulo enembile.
