Ukuhlelwa nohlalutyo lweempawu of PCB ubhedu olungenamngxuma

Ukwahlula kunye neempawu zobhedu olungenamngxuma

1. Akukho bhedu kwi-PTH hole: Uluhlu lombane lweplate yethusi phezu komhlaba lufana kwaye luqhelekileyo, kwaye umbane wombane weplate emngxunyeni usasazwa ngokulinganayo ukusuka emngxunyeni ukuya kwi-fracture. Emva koqhagamshelo lombane, ukuphuka kugutyungelwa ngumaleko wombane.

2 Akukho bhedu kumngxuma obhityileyo wobhedu ebhodini:

(1) Akukho bhedu kwimingxuma yobhedu yombane ecekethekileyo yebhodi iphela-amaleko ombane obhedu olungaphezulu kunye neepleyiti zobhedu zomngxuma zibhityile kakhulu. Umzobo umaleko wombane ovalelweyo;

(2) Akukho bhedu kumngxuma obhityileyo wobhedu wombane emngxunyeni- umaleko wombane wepleyiti yobhedu yomphezulu ufana kwaye uqhelekile, kwaye umaleko wombane womngxuma osemngxunyeni ubonisa indlela ehlayo yokulola ukusuka umngxuma ekuqhekekeni, kwaye ukwaphuka ngokubanzi kuphakathi komngxuma. Umaleko wobhedu ngasekhohlo

Ilungelo linokufana okulungileyo kunye ne-symmetry, kwaye i-fracture ihlanganiswe ngumbane wombane emva komfanekiso wombane.

3. Lungisa imingxuma eyaphukileyo:

(1) Ukuhlolwa kobhedu kunye nokulungiswa kwemingxuma eyaphukileyo-umaleko wombane wepleyiti yobhedu yomphezulu ufana kwaye uqhelekile, umaleko wombane weplate yobhedu yomngxuma awukho utyekelo lokulola, kwaye ukwaphuka kungaqhelekanga, okunokuthi kubonakale emngxunyeni okanye embindini womngxuma, kwaye kaninzi kubonakala kudonga lomngxuma Amaqhuma arhabaxa kunye nezinye iziphene, ukwaphuka kugqunywe ngumaleko wombane emva koqhagamshelo lombane.

(2) Ukuhlolwa kwe-Corrosion kunye nokulungiswa komngxuma ofihliweyo-umaleko wombane wepleyiti yobhedu engaphezulu ufana kwaye uqhelekile, umaleko wombane wepleyiti yobhedu yomngxuma awukho utyekelo lokulola, kwaye ukwaphuka kungaqhelekanga, okunokuthi kubonakale kwindawo umngxuma okanye embindini womngxuma, kwaye idla ngokubonakala kudonga lomngxuma Amaqhuma arhabaxa kunye nezinye iziphene, umaleko wombane ekuqhekekeni awugqunywanga ngumaleko wombane webhodi.

4. Akukho bhedu kumngxuma weplagi: Emva kokuba umfanekiso ufakwe kwi-electro-etched, kukho izinto ezicacileyo ezincanyathiselwe emngxunyeni, uninzi lodonga lomngxuma luxhonywe, kwaye umfanekiso wombane kwindawo yokwaphuka awuwugubungeli umbane. umaleko webhodi.

5. Akukho bhedu emngxunyeni wombane: umbane wombane kwi-fracture awufaki umbane webhodi-ubunzima bombane kunye nombane webhodi ufana, kwaye ukuphuka kufana; umaleko wombane uthambekele ekuloleni de uphele, kwaye umaleko wombane webhodi Uluhlu ludlula umaleko wombane kwaye luyaqhubeka nokwandisa umgama othile ngaphambi kokuba luqhawulwe.

Umkhombandlela wophuculo:

1. Ukusebenza (ibhodi ephezulu nangaphantsi, ukusetwa kweparameter, ukugcinwa, ukuphatha okungaqhelekanga);

2. Izixhobo (i-crane, i-feeder, ipeni yokufudumeza, i-vibration, ukupompa, umjikelezo wokucoca);

3. Izinto (iipleyiti, iipotions);

4. Iindlela (iiparameter, iinkqubo, iinkqubo kunye nolawulo lomgangatho);

5. Okusingqongileyo (inguqu ebangelwa ukungcola, ukungcola kunye nokuphazamiseka).

6. Umlinganiselo (uvavanyo lweyeza, ukuhlolwa kobhedu kunye nokuhlolwa okubonakalayo).
