Iqhaza elibalulekile lekhebula ledatha ukudlulisa amasignali edatha. Kodwa uma siyisebenzisa ngempela, kungase kube nazo zonke izinhlobo zolwazi lokuphazamiseka okungcolile. Ake sicabange uma lezi zimpawu eziphazamisayo zifaka umqhubi wangaphakathi wekhebula ledatha futhi zibekwe phezulu kusiginali edluliselwe ekuqaleni, kungenzeka yini ukuphazamisa noma ukuguqula isignali edluliselwe ekuqaleni, ngaleyo ndlela kubangele ukulahlekelwa amasignali awusizo noma izinkinga?
Ikhebula
Isendlalelo esilukiweyo nesendlalelo se-aluminium foil sivikela futhi sivikele ulwazi oludlulisiwe. Vele akuzona zonke izintambo zedatha ezinezingqimba ezimbili ezivikelayo, ezinye zinesendlalelo sokuvikela eziningi, ezinye zinenye kuphela, noma azikho nhlobo. Isendlalelo esivikelayo siwukuhlukaniswa kwensimbi phakathi kwezifunda ezimbili zendawo ukuze kulawuleke ukungeniswa kanye nemisebe yamagagasi kagesi, kazibuthe kanye nozibuthe kagesi ukusuka kwesinye isifunda ukuya kwesinye.
Ikakhulukazi, kuwukuzungeza amakhora ekhondatha ngezihlangu ukuze uwavimbele ukuthi angaphazanyiswa amasimu/amasiginali wokuphazamiseka kagesi wangaphandle, futhi ngesikhathi esifanayo ukuvimbela ukuphazamiseka kwezinkambu/amasignali we-electromagnetic ezintanjeni ukuthi zingasakazeki ngaphandle.
Ngokuvamile, amakhebuli esikhuluma ngawo ikakhulukazi ahlanganisa izinhlobo ezine zezintambo eziwumgogodla, amapheya asontekile, izintambo ezivikelwe kanye nezintambo ezingamakhoaxial. Lezi zinhlobo ezine zezintambo zisebenzisa izinto ezihlukene futhi zinezindlela ezihlukene zokumelana nokuphazanyiswa nguzibuthe kagesi.
Isakhiwo esisontekile siwuhlobo oluvame ukusetshenziswa kakhulu lwesakhiwo sekhebula. Isakhiwo sayo silula, kodwa sinamandla okunciphisa ngokulinganayo ukuphazamiseka kwe-electromagnetic. Ngokuvamile, ukuphakama kwezinga lokusonteka kwezintambo zayo ezisontekile, kuba ngcono umphumela wokuvikela ozuzwayo. Impahla yangaphakathi yekhebula evikelekile inomsebenzi wokuqhuba noma wokuqhuba kazibuthe, ukuze kwakhiwe inetha elivikelayo futhi kuzuzwe umphumela ongcono kakhulu wokugxambukela kuzibuthe. Kukhona ungqimba oluvikela insimbi kukhebula le-coaxial, okuyinhloko ngenxa yefomu layo langaphakathi eligcwele impahla, elingenayo nje kuphela Inenzuzo ekudlulisweni kwezimpawu futhi ithuthukise kakhulu umphumela wokuvikela. Namuhla sizokhuluma ngezinhlobo kanye nokusetshenziswa kwezinto zokuvikela ikhebula.
I-Aluminium foil I-Mylar tape: I-aluminium foil I-Mylar tape yenziwe nge-aluminium foil njengento eyisisekelo, ifilimu ye-polyester njengento yokuqinisa, ehlanganiswe ne-polyurethane glue, yelashwa ekushiseni okuphezulu, bese iyasikwa. I-Aluminium foil I-Mylar tape isetshenziswa kakhulu esikrinini sokuvikela izintambo zokuxhumana. I-aluminium foil ye-Mylar tape ihlanganisa ucwecwe lwe-aluminium ohlangothini olulodwa, ucwecwe lwe-aluminium enamacala amabili, ucwecwe olucijile lwe-aluminium, ucwecwe lwe-aluminium oluncibilika oshisayo, itheyiphu ye-aluminium foil, kanye ne-aluminium-plastic composite tape; ungqimba lwe-aluminium luhlinzeka ngokusebenza kahle kagesi, ukuvikela kanye nokulwa nokugqwala, kungakwazi ukuzivumelanisa nezidingo ezihlukahlukene.
I-aluminium foil ye-Mylar tape
I-Aluminium foil I-Mylar tape isetshenziswa kakhulu ukuvikela amagagasi kagesi kagesi aphezulu ukuze kuvinjelwe amagagasi kagesi aphezulu ukuthi axhumane namakhondaktha ekhebula ukuze kukhiqizwe amandla amanje kanye nokwandisa i-crosstalk. Uma igagasi lozibuthe we-high-frequency electromagnetic wave lithinta ucwecwe lwe-aluminium, ngokomthetho ka-Faraday wokungeniswa kuka-electromagnetic, igagasi kazibuthe kagesi lizonamathela phezu kwecwecwe le-aluminium futhi likhiqize i-current induced. Ngalesi sikhathi, i-conductor iyadingeka ukuze iqondise amandla amanje emhlabathini ukuze agweme amandla akhona ukuthi angaphazamisi isignali yokudlulisela.
Isendlalelo esilukiwe (ukuvikela insimbi) njengezintambo zethusi/i-aluminium-magnesium alloy. Isendlalelo sokuvikela insimbi senziwa izintambo zensimbi ezinesakhiwo esithile sokuluka ngokusebenzisa imishini yokuluka. Izinto zokuvikela insimbi ngokuvamile izintambo zethusi (izintambo zethusi ezithini), izintambo ze-aluminium alloy, izintambo ze-aluminiyamu ezigqoke ithusi, itheyiphu yethusi(ithayiphu yensimbi ehlanganiswe ngopulasitiki), itheyiphu ye-aluminium (ithayiphu ye-aluminium ehlanganiswe ngopulasitiki), itheyiphu yensimbi nezinye izinto.
I-Copper Strip
Ngokuhambisana nokuluka kwensimbi, amapharamitha esakhiwo ahlukene anokusebenza okuhlukile kokuvikela, ukusebenza kahle kokuvikela kwesendlalelo esilukiwe akuhlobene kuphela nokuhamba kukagesi, ukufinyeleleka kukazibuthe kanye neminye imingcele yesakhiwo sensimbi uqobo. Futhi uma izendlalelo eziningi, ukumbozwa okukhulu, i-engeli yokuluka iba yincane, futhi kuba ngcono nokusebenza kokuvikela kwesendlalelo esilukiwe. I-angle yokuluka kufanele ilawulwe phakathi kuka-30-45 °.
Ngokulukwa kwesendlalelo esisodwa, izinga lokumboza lingcono kakhulu libe ngaphezu kwama-80%, ukuze liguqulwe libe ezinye izinhlobo zamandla njengamandla okushisa, amandla angaba khona nezinye izinhlobo zamandla ngokulahleka kwe-hysteresis, ukulahleka kwe-dielectric, ukulahlekelwa ukumelana, njll. , futhi isebenzise amandla angadingekile ukuze kuzuzwe umphumela wokuvikela nokumunca amagagasi kagesi.
