Ukugquma ngentsimbi yinkqubo esetyenziswa kakhulu kumashishini ahlukeneyo, kwaye ibandakanya ukusetyenziswa komaleko omncinci wesinyithi kwi-substrate ukuphucula inkangeleko yayo, ukuphucula ukumelana nokugqwala kwayo, okanye ukubonelela ngezinye iingenelo zokusebenza. Inkqubo yokugquma ngentsimbi ifuna ukusetyenziswa kwe-rectifier, eyisixhobo esibalulekileyo esilawula ukuhamba kombane ngexesha lenkqubo yokugquma. Kweli nqaku, siza kuhlola iintlobo ezahlukeneyo zokugquma ngentsimbi kunye nendima ye-rectifier kwinkqubo yokugquma.
Iintlobo zeSitya sokuGcina isinyithi
Ukufakelwa ngombane
I-Electroplating lolona hlobo luqhelekileyo lwe-metal plating kwaye ibandakanya ukusetyenziswa kombane ukuze kufakwe umaleko omncinci wesinyithi kumphezulu oqhubayo. I-substrate eza kufakelwa ifakwa kwisisombululo se-electrolyte esinee-ion zesinyithi, kwaye i-rectifier isetyenziselwa ukulawula ukuhamba kombane ukuya ebhafini ye-plating. Iintsimbi eziqhelekileyo ezisetyenziswa kwi-electroplating ziquka i-nickel, i-copper, i-chromium, kunye negolide.
Isingxobo esingena-electro
Ngokungafaniyo ne-electroplating, i-electroless plating ayifuni ukusetyenziswa kombane. Endaweni yoko, inkqubo ye-plating ixhomekeke kwi-chemical reaction ukuze ifake umaleko wesinyithi kwi-substrate. Le ndlela idla ngokusetyenziselwa ukupeyinta izinto ezingahambisi umbane ezifana neeplastiki kunye neeseramikhi. I-electroless plating inika ubukhulu obufanayo be-coating kwaye ingasetyenziselwa ukupeyinta uluhlu olubanzi lweesinyithi, kubandakanya i-nickel, i-copper, kunye ne-cobalt.
Isingxobo sokuntywiliselwa
I-immersion plating, eyaziwa ngokuba yi-autocatalytic plating, luhlobo lwe-metal plating olungadingi mthombo wamandla wangaphandle. Kule nkqubo, i-substrate ifakwa kwisisombululo esinee-ion zesinyithi, kunye nee-reducing agents ezenza kube lula ukufakwa komaleko wesinyithi. I-immersion plating isetyenziswa rhoqo ekufakeni iindawo ezincinci, ezinobume obunzima kwaye ifanelekile ngokukodwa ekufezekiseni ukugqunywa okufanayo kwiindawo ezintsonkothileyo.
Ibhrashi Plating
Ukugquma ngebrashi yindlela yokugquma ephathekayo neguquguqukayo equka ukusetyenziswa kwesixhobo esiphathwayo ukugquma iindawo ezithile zenxalenye. Le ndlela idla ngokusetyenziswa ekulungiseni iindawo ezithile, ukulungisa izinto, okanye ukugquma iindawo ezinkulu ekunzima ukuzihambisa kwi-plate tank. Ukugquma ngebrashi kungenziwa kusetyenziswa iintlobo ngeentlobo zesinyithi, kubandakanya i-nickel, i-copper, kunye negolide.
Indima yoMlungisi kwiSitya seNsimbi
I-rectifier yinxalenye ebalulekileyo kwinkqubo ye-metal plating, njengoko ilawula ukuhamba kombane ukuya kwi-plating bath. I-rectifier iguqula i-alternating current (AC) ukusuka kumthombo wamandla ukuya kwi-direct current (DC), efunekayo kwinkqubo ye-electroplating. I-rectifier ikwalawula i-voltage kunye ne-amperage ukuqinisekisa ukuba inkqubo ye-plating iqhubeka ngesantya esifunekayo kwaye ivelisa i-coating efanayo.
Kwi-electroplating, i-rectifier ilawula ukufakwa kwee-ion zesinyithi kwi-substrate ngokulungelelanisa uxinano lwangoku kunye nobude benkqubo ye-plating. Iintsimbi ezahlukeneyo zifuna iiparameter ezithile ze-plating, kwaye i-rectifier ivumela ulawulo oluchanekileyo kwezi zinto ziguquguqukayo ukuze kufezekiswe ubukhulu kunye nomgangatho we-plating oyifunayo.
Kwiplating engenambane kunye neplating yokuntywila, i-rectifier isenokungafuneki, njengoko ezi nkqubo zingaxhomekekanga kumbane wangaphandle. Nangona kunjalo, kwezinye iimeko, i-rectifier isenokusetyenziswa ukulawula iinkqubo ezincedisayo ezifana nokushukunyiswa okanye ukufudunyezwa kwesisombululo seplating.
Ukukhetha i-Rectifier efanelekileyo ye-Metal Plating
Xa ukhetha isixhobo sokulungisa izinto zesinyithi, kufuneka kuqwalaselwe izinto ezininzi ukuqinisekisa ukusebenza kakuhle kwesixhobo sokulungisa izinto. Ezi zinto ziquka:
Iimfuneko zamandla ombane kunye neVoltage: I-rectifier kufuneka ikwazi ukuhambisa amanqanaba afunekayo amandla ombane kunye ne-voltage kwi-plating bath, ithathela ingqalelo ubungakanani beendawo ezifakelwayo kunye neeparamitha ezithile zeplating.
Iimpawu zoLawulo kunye nokuBeka eSweni: Isixhobo sokulungisa izinto esilungileyo kufuneka sinike ulawulo oluchanekileyo lwamandla ombane kunye nombane, kunye nokukwazi ukujonga inkqubela phambili yenkqubo yokubeka iplati kunye nokuqinisekisa umgangatho ohambelanayo.
Ukusebenza kakuhle nokuthembeka: Isilungisi kufuneka sisebenzise amandla kakuhle kwaye sithembeke, sibe neempawu zokhuseleko ezakhelwe ngaphakathi ukukhusela ukugqithisa, ii-short circuits, kunye nezinye iingozi ezinokubakho.
Ukuhambelana nezisombululo zePlating: I-rectifier kufuneka ihambelane nezisombululo ezithile zeplating kunye neenkqubo ezisetyenziswayo kwisicelo, kwaye kufuneka yakhiwe ngezinto ezimelana nokugqwala kunye nokuvezwa ziikhemikhali.
Ukuqukumbela, i-metal plating yinkqubo eguquguqukayo nebalulekileyo kumashishini ahlukeneyo, kwaye ukukhethwa kohlobo olufanelekileyo lwendlela ye-plating kunye ne-rectifier efanelekileyo kubalulekile ekufezekiseni iingubo ezisemgangathweni ophezulu nezifanayo. Nokuba yi-electroplating, i-electroless plating, i-immersion plating, okanye i-brush plating, indlela nganye inika iingenelo ezikhethekileyo kwaye ifanelekile kwizicelo ezahlukeneyo. Ngokuqonda ngokufanelekileyo iintlobo ezahlukeneyo ze-metal plating kunye nendima ye-rectifier, abavelisi kunye nabafakeli be-plate banokwenza izigqibo ezinolwazi ukuhlangabezana neemfuno zabo ezithile ze-plating kunye nokufezekisa ukugqitywa komphezulu okufunekayo kunye neempawu zokusebenza.
