Iteyiphu yokugqumaIsetyenziswa kakhulu kushishino lokubeka izinto ze-elektroniki. Isetyenziswa kunye neteyiphu yokuthwala ukugcina izinto ze-elektroniki ezifana nee-resistor, ii-capacitors, ii-transistors, ii-diodes, njl.njl. ezipokothweni zeteyiphu yokuthwala.
Iteyiphu yokugquma idla ngokusekwe kwifilimu yepolyester okanye yepolypropylene, kwaye idityaniswe okanye igqunywe ngeeleya ezahlukeneyo ezisebenzayo (umaleko ochasene nokuma, umaleko wokuncamathelisa, njl.njl.). Kwaye ivalwe phezulu kwipokotho kwiteyiphu yokuthwala ukuze yenze indawo evaliweyo, esetyenziselwa ukukhusela izinto ze-elektroniki ekungcoleni nasekonakaleni ngexesha lokuthuthwa.
Ngexesha lokubekwa kwezinto ze-elektroniki, iteyiphu yokugquma iyaxotyulwa, kwaye izixhobo zokubeka ngokuzenzekelayo zibeka ngokuchanekileyo izinto epokothweni ngomngxuma we-sprocket yeteyiphu yokuthwala, kwaye emva koko zizithathe zize zibeke kwibhodi yesekethe edibeneyo (ibhodi ye-PCB) ngokulandelelana.
Uhlu lweeteyiphu zokugquma
A) Ngobubanzi beteyiphu yokugquma
Ukuze kuhambelane nobubanzi obahlukeneyo beteyiphu yokuthwala, iiteyiphu zokugquma zenziwe ngobubanzi obahlukeneyo. Ububanzi obuqhelekileyo yi-5.3 mm (5.4 mm), 9.3 mm, 13.3 mm, 21.3 mm, 25.5 mm, 37.5 mm, njl.
B) Ngeempawu zokutywina
Ngokweempawu zokubopha kunye nokukhuhla kwiteyiphu yokuthwala, iiteyiphu zokugquma zingahlulwa zibe ziintlobo ezintathu:iteyiphu yokugquma esebenza ngobushushu (HAA), iteyiphu yokugquma ebuthathaka kuxinzelelo (PSA), kunye neteyiphu yokugquma entsha yendalo yonke (UCT).
1. Iteyiphu yokugquma evuselelwayo ngobushushu (HAA)
Ukutywinwa kweteyiphu yokugquma esebenza ngobushushu kufezekiswa bubushushu kunye noxinzelelo oluvela kwibhloko yokutywina yomatshini wokutywina. Ngelixa iglu yokunyibilika eshushu inyibilika kumphezulu wokutywina weteyiphu yokunxiba, iteyiphu yokugquma iyacinezelwa kwaye itywinwe kwiteyiphu yokunxiba. Iteyiphu yokugquma esebenza ngobushushu ayinayo i-viscosity kubushushu begumbi, kodwa iba ncangathi emva kokufudumeza.
2. Iglu ebuthathaka kuxinzelelo (i-PSA)
Ukutywinwa kwetheyiphu yokugquma ebuthathaka kuxinzelelo kwenziwa ngomatshini wokutywina osebenzisa uxinzelelo oluqhubekayo ngerola yoxinzelelo, unyanzela iglue ebuthathaka kuxinzelelo kwitheyiphu yokugquma ukuba inamathele kwitheyiphu yokuthwala. Umphetho weglue yokugquma ebuthathaka kumacala omabini unamathela kubushushu begumbi kwaye ungasetyenziswa ngaphandle kokufudumeza.
3. Iteyiphu entsha ye-Universal Cover (UCT)
Amandla okuxobuka kweetayiphu zokugquma ezithengiswayo axhomekeke kakhulu kumandla okuncamathela kweglue. Nangona kunjalo, xa iglue efanayo isetyenziswa kwizinto ezahlukeneyo zomphezulu kwiteyiphu yokuthwala, amandla okuncamathela ayahluka. Amandla okuncamathela kweglue ayahluka phantsi kweemeko ezahlukeneyo zobushushu kunye neemeko zokwaluphala. Ukongeza, kunokubakho ungcoliseko lweglue eseleyo ngexesha lokuxobuka.
Ukusombulula ezi ngxaki zithile, uhlobo olutsha lweteyipu yokugquma ebanzi luye lwaziswa kwimarike. Amandla okuxobula awaxhomekekanga kumandla okuncamathelisa eglu. Endaweni yoko, kukho imingxunya emibini enzulu esikwe kwifilimu esisiseko yeteyipu yokugquma ngokusebenzisa ukucubungula ngokuchanekileyo koomatshini.
Xa ixobuka, iteyiphu yokugquma iyakrazula kwimiqolo, kwaye amandla okuxobuka axhomekekanga kumandla okuncamathela eglu, echaphazeleka kuphela bubunzulu bemiqolo kunye namandla oomatshini efilimu, ukuqinisekisa uzinzo lwamandla okuxobuka. Ukongeza, kuba yinxalenye ephakathi yeteyiphu yokugquma kuphela exobukayo ngexesha lokuxobuka, ngelixa amacala omabini eteyiphu yokugquma ehlala enamathele kumgca wokutywina weteyiphu yokuthwala, ikwanciphisa ungcoliseko lweglu eseleyo kunye nenkunkuma kwizixhobo nakwiinxalenye.
