Ukuguquguquka kohlangothi olulodwa ibhodi yesifunda ephrintiwe (I-PCB) inezinzuzo eziningi lapho isetshenziswa ekupakisheni noma njengengxenye yohlelo. Lawa ma-PCBS abelokhu ekhona kusukela ngawo-1950 futhi asathandwa namanje. Lo mbhalo uhlola izizathu zokuqhubeka nokubuyekezwa kwabo okuhle.

Isakhiwo esiyisisekelo sesekhethi eyodwa – emaceleni eguquguqukayo

Ama-PCBS ayizinhlangothi ezi-XNUMX aqukethe ungqimba olulodwa lwezinto ezihambayo futhi alungele ukwakheka kwabantu abaphansi. Isakhiwo esiyisisekelo se-PCB esinezinhlangothi esisodwa sifaka:

Isendlalelo se-polyimide

Isendlalelo seglue

Isendlalelo se-conductor – ithusi

Isendlalelo se-polyamide

Izimo zokusebenzisa i-PCB eyodwa

Isendlalelo se-conductor – ithusi

ungqimba lweglue

Isevisi eguqukayo / ukufakwa

Izicelo ze-PCB ezihlangothini olulodwa

Ama-PCBS ohlangothini olulodwa alula kakhulu, kepha angasetshenziswa kumasekethe ahlukahlukene anzima. Nazi ezinye izinhlelo zokusebenza ezidumile ze-PCBS ezinamacala owodwa.

Izinzuzo zesekhethi yohlangothi olulodwa oluguquguqukayo

Izinzuzo ezilandelayo ze-PCBS yohlangothi olulodwa zibonisa ukuduma kwazo:

Amathuba amancane ezinkinga zokukhiqiza: Ngamasu wokukhiqiza okuzenzakalelayo nokuklama okunembile, amasekethe ohlangothi olulodwa aguquguqukayo anciphisa amathuba wephutha lomuntu. Lokhu kuphakamisa amathuba amancane okudala inkinga.

Okungabizi kakhulu: Lesi ngesinye sezishayeli eziyinhloko zokuthandwa kwe-PCBS ngabaqhubi bezethusi ababodwa. Lezi zifunda zidinga umsebenzi omncane ukuze zihlangane. Imvamisa, amasistimu wokuxhumeka okuphelele ayashintshwa noma afakwe ebhodini ngalinye le-PC eliqinile. Lokhu kusiza ukunciphisa amaphutha nokulawula izindleko zokukhiqiza. Ngakho-ke, kungakhathaliseki ukuthi isetshenziselwa i-prototyping, idizayini yevolumu encane noma enkulu, izindleko ziphansi futhi isikhathi sokuguqula sifushane.

Ukuthembeka: I-PCB eguquguqukayo yohlangothi olulodwa ingagotshwa futhi ihanjiswe ngaphandle kwanoma yiliphi ithuba lokwehluleka. Ukuzinza okushisayo kwama-polyamides kwenza i-PCBS ikwazi ukumelana namazinga okushisa aphezulu namazinga okushisa.

Isisindo esincishisiwe nosayizi wephakheji: Ama-PCBS ohlangothini olulodwa anezinsimbi anezicucwana ezincane. Lokhu kuzaca kukhuluma ngomklamo owenziwe lula, ukuvumelana nezimo nokuqina. Lokhu kusiza ukonga isisindo nokunciphisa usayizi wephakeji. Ama-PCBS ayizinhlangothi zombili ngokuqinisekile azoqhubeka nokuthandwa njengoba isidingo samasekethe anesisindo esiphansi siqhubeka nokukhula.
