Etching ibhodi i-hydrogen peroxide kanye citric acid: sicubungula izimali ubuqili

Etching ibhodi i-hydrogen peroxide kanye citric acid - Indlela athandwa kakhulu nge radio amateur. Kuyinto ngendlela ephephile yokuthola ulungele izakhi nokunamathisela ngomthofu we ngendwangu ithuluzi esizayo hhayi nje kuphela ukuthi anejubane kodwa futhi.

Indlela ezihlalayo ibhodi esikhathini esidlule?

Ngaphambili, ukwenza ephrintiwe wesifunda ibhodi, ke wawudinga umzamo. Umhlangano wesifunda wokuqala ezifuywa ephepheni, bese iyashaya nalutho bese idluliselwe amathrekhi phezu PCB noma ucwecwe getinaks, ukusebenzisa umkhiqizo upende. Ngemuva omiswe wadabula enamathela yayo, futhi ibhodi lalikhungethwe esitsheni for Etching edlelweni.

Into enzima kunazo zonke kwakufanele Imali ushevu. Njengoba le njongo ngesisekelo enkangala usebenzisa chloride ferric. Lesi sikole umsakazo zindlela kwakuyingcosana cha, kodwa lapha ekhaya kwakudingeka bafune enye, njengoba ngokuvamile kwenziwa kakhulu bluestone.

ibhodi ukucutshungulwa eyenziwa nalo elinye imfihlo: esikhundleni sakhe ngoba ibhodi kwagxila Ukuboshelwa. Amanye amathrekhi buqeda, futhi kwezinye izindawo nedotravlivalas ebusweni. Zonke ngenxa yokungazi wezingcweti noma esebenza isixazululo Luzhny.

izindlela zesimanje ukucutshungulwa amabhodi

Etching ibhodi i-hydrogen peroxide kanye citric acid akuyona eseyintsha. Abaningi abake bezwa le ndlela ngaphambili. Ngokukhetha lokhu ukuqeqeshwa ibhodi kukho, uyothola akukho inzuzo kuqhathaniswa ne Etching e chloride ferric. Ngokwesibonelo, ukucutshungulwa izinga, ukuphepha kanye peroxide kwemvelo lihambisana i oxidant.

Recipe ukucutshungulwa ikhadi indlu

Okudingekayo ukuze enze etching lebhodi-hydrogen peroxide kanye citric acid, kungatholakala imithi yakhe iKhabhinethi ekhishini, noma ungathenga ngaphandle kwezinkinga. Enye inzuzo ukucutshungulwa abahlukene amabhodi ngendlela - izindleko izithako ukudala isixazululo. Yilokho enye inzuzo hydrogen ingxube - kuzoba ishibhile chloride ferric.

ingxenye ukwakheka

• Hydrogen peroxide 3% th - 100 ml.
• Citric acid - 30 amagremu.
• Sodium chloride - 5 amagremu (njengoba ikhomponethi asizayo of ukusabela).
• Amanzi (uma kunesidingo).

Okubalulekile! Isixazululo uzilungiselele ngezabelo banele ukuba etch ucwecwe ngethusi ukujiya 35 microns futhi indawo sq 100. cm.

Ilungiselela ibhodi

1. Dweba futhi uprinte izindleko.
2. Sika obudingekayo ucezu PCB.
3. Dlulisa toner phezu PCB futhi ake cwilisa, bese ususa.

Indlela ukulungiselela isixazululo?

1. Preheat hydrogen peroxide: ukubeka ibhodlela okugeza amanzi bese ulinda kuze izinga lokushisa kwe-izinto ezimbili ziyahambisana.
2. Thatha inkomishi. Noma yimuphi ofanele, kodwa hhayi metal.
3. Thela peroxide osuke usushisa kakade ukuba ihlanzekile futhi yomile imbiza vsypte citric acid.
4. Hlanganisa kahle.
5. Nakuba sibhebhezela, engeza usawoti, okuyinto uba isixazululo kulethe.

Indlela etch ebhodini?

Ukuze etch le peroxide ibhodi hydrogen ne citric acid yadlula ngokushesha, ungasebenzisa iziqukathi ezimbili. Vele ubeke ezincane umthamo edlelweni emgqonyeni ezinkulu futhi uthele amanzi ashisayo kuwo. Lokhu kuzokwenza esheshisa futhi ukuthuthukisa inqubo.

Etching ibhodi p-D-hydrogen peroxide wenziwa kanje: icala ibekwe endaweni ohlangothini edlelweni lapho amathrekhi basondela phansi imikhiqizo kwamazinyo zehliswa kalula phansi isitsha. Ukuze basabela iyunifomu isisombululo kufanele kube ngezikhathi ezithile ukuze bagqugquzele kancane. Yonke inqubo kuthatha imizuzu engaphansi kwengu-10.

Lapho beqeda insangu icala kumele neutralized futhi siyakazwe ngaphansi kwamanzi agelezayo.

Le ndlela yokukhokha ngokuphelele ukwelashwa okuphephile. Yenza inkokhelo manje kungenzeka emsebenzini, ekhaya futhi ehhovisi futhi sisebenze reagents ezingaphephile ngesikhathi esifanayo akudingekile.

Okubalulekile! Uma ikhambi Foam okuningi, usawoti wena thrashed kakhulu. Meanly peroxide ngaphezulu, ngaphandle kwalokho ukusabela kuyokwenzeka phezu kungenzeka izindlela asebenzayo lilimele.

Uma ukusabela wena ukhiphe ibhodi ulubheke, ngeke uphawule umehluko, uma kuqhathaniswa indlela ephrintiwe wesifunda ibhodi Etching e chloride ferric, bamane ungapheli. Umehluko omkhulu - ngokushesha odlulayo ukuphendula futhi inqubo kancane esiyingozi abantu.

Wazi kanjani ukuthi yezinhlinzeko isiyenezelwe kakade kwagxila?

I-hydrogen-esidi naphakathi ukusabela okuphuma ngokuvumelana ifomula: Cu + H3Cit + H2O2 → H [CuCit] + 2H2O. Etching we PCB ku peroxide hydrogen angabhekwa ephelele lapho wayeka iyiphi ukusabela isixazululo: akuseyona fizzing noma olubilayo.

Ibhodi siphelile zihlanjululwa futhi ngamanzi. Toner noma inki ukugeza nge acetone. Khona-ke Sula ngokucophelela ebhodi kanye degreased.

Okubalulekile! Hlola ubuqotho amathrekhi ebhodini emva kokwelashwa. wesifunda esonakele ngeke zisebenze.

Njengoba ubona, Etching ibhodi i-hydrogen peroxide ekhaya akukhona kuphela kungenzeka, kodwa futhi iphephile. Akukho nzima ukuthola izithako ezidingekayo ukulungisa indlela yokwakheka etching, futhi inqubo kuthatha imizuzu engaphansi kwengu-15. Namuhla, njalo amateur radio, sibonga iseluleko esilula futhi enembile ungazama ekhaya ngaphandle ngowabo nabanye.
