Iteyiphu yobushushu obuphezulu ibhekisa kwiiteyiphu zokuncamathelisa ezisetyenziswa kwindawo yokusebenza yobushushu obuphezulu.Ngeyona nto iphambili yokukhupha ngaphandle kokushiyeka, iiteyiphu zobushushu obuphezulu zisetyenziswa ikakhulu njengemaski kunye nomsebenzi wokukhusela ngexesha lokugquma iPowder, iPlating, ukuprintwa kwebhodi yesekethe, i-wave soldering masking kunye nokufakwa kwe-SMT.Ingasetyenziswa kuluhlu olubanzi lwesicelo soshishino, njengeshishini le-Electronic, ishishini lezeMoto, ishishini le-Aerospace, njl.
Apha singathanda ukuhlela iiteyiphu zeteyiphu ephezulu njengangezantsi:
Okokuqala, ubushushu obuphezulu bunokwahlulwa ngokweefilimu ezahlukeneyo zokuthwala.
iTape yePolyimide,ekwabizwa ngokuba yiKapton okanye iGolden Finger, eyona nto ixabisa kakhulu ukuxhathisa ubushushu emarikeni ngokufutshane usebenzisa ukumelana nobushushu obuphezulu ukuba ibe yi-350 ℃.Ubukhulu ngokubanzi beefilimu zeKapton ziyi-12.5um, 25um, 35um, 50um, 75um, 100um kunye ne-125um, kwaye umzi-mveliso wethu unako ukwenza obunye ubukhulu obukhethekileyo obufana ne-150um, 200um okanye 225um ngokwezicelo zomthengi.Umbala o-Amber kunye noMnyama ngowona mbala uqhelekileyo, kwaye umbala omnyama unokwenziwa njengombala ocwebezelayo okanye onamatte.Eminye imibala efana noLuhlaza, eBomvu okanye eNgacacanga nayo inokwenziwa ngokwezifiso nge-MOQ ethile kunye neendleko eziphezulu.
I-Polyester ikwashunqulelwe njenge-PET (Igama lekhemikhali yi-polyethylene terephthalate, ekwabizwa ngokubaIteyiphu yeMYLAR).Ubushushu bayo bokunyibilika bungama-240℃, kwaye obona bushushu buphezulu bokusebenza bungama-230℃, ngelixa obona bushushu bokusebenza buphakathi kwe-180℃.Iimpawu zefilimu yePET ezinokuhanjiswa okuphezulu kunye nexabiso eliphantsi, elingasetyenziswanga kuphela njengetape ukumelana nobushushu obuphezulukodwa njengokoIteyiphu ye-Mylar insulationokanyeIfilimu yokukhusela ye-PET.Uninzi lweefilimu ze-PET zinombala ocacileyo, ngaphandle komnye umbala onjengombala we-Amber, oBomvu, oBlue kunye nombala oLuhlaza.
- 3. Isiphathi selaphu leglasi
Ilaphu leglasi lenziwe ngefayibha yeglasi kwaye lilukwe njengelaphu, kwaye ubukhulu becala yi-130um ngombala omhlophe.Ilaphu leglasi linamandla okuqina okuqinileyo kunye nokuxhathisa ukukrazula okunokusetyenziswa njengokusonga okanye ukulungisa i-transformer, iMoto, ibhetri ye-lithium okanye ukugcinwa kwezixhobo zemigodi.
Ilaphu lefiber yeglasi lenziwe ngeTeflon ephathwayo kwaye igqunywe nge-adhesive ye-silicone emva konyango lwe-nanochemical.Ine-anti-stick, ubushushu obuphezulu kunye neempawu zokumelana neekhemikhali, ezibonelela ngesisombululo esomeleleyo ekupakishweni kunye noomatshini bokutywinwa kobushushu.Ubukhulu obuqhelekileyo belaphu leglasi yeTeflon yi-80um kunye ne-130um, obunye ubukhulu obukhethekileyo obufana ne-50um, i-150um okanye i-250um bunokulungiswa ngokwesicelo sabathengi.
PTFE Film iqulathe ukunqunyanyiswa PTFE resin ngokubumba, sintering, ukupholisa kwi blank.Ineempawu zedielectric ezigqwesileyo, ukumelana nokuguga kunye neempawu zokumelana nomhlwa ezidla ngokusetyenziswa ekutywineni intambo, idoping yePipe, imibhobho yamanzi kunye nokusonga.Kukho imibala emithathu yokhetho, emhlophe, emdaka kunye emnyama.
Okwesibini, iiteyiphu zobushushu obuphezulu zinokwahlulwa zibe ziindidi ezahlukeneyo njengoko ngezantsi ngokwezinto zokuncamathelisa ezahlukeneyo.
- 1. Isincamathelisi seSilicone
Iglu yeSilicone yeyona nto incamathelayo yokumelana nobushushu.Iyakwazi ukumelana nobushushu obude ukuya kwi-260℃ kunye nobushushu obufutshane ukuya kuma-300℃.Kukho iinkqubo ezimbini eziphambili zeglue ye-silicone eyi-BPO catalytic system kunye neplatinam catalytic system.Inkqubo ye-BPO inexabiso eliphantsi kwaye inokumelana nobushushu obungcono, kodwa iya kwenza iimolekyuli ezincinci zesilicon dioxide, eziya kuchaphazela ukucoceka kwemveliso.Inkqubo ye-platinum catalyst inokumelana nokushisa okuphantsi, kodwa ukucoceka okungcono, okuqhelekileyo kusetyenziselwa ukwenza iimveliso zefilimu ezikhuselayo ze-silicone.
- 2. I-Acrylic adhesive
Iglu ye-Acrylic inoluhlu olubanzi lwe-viscosity yokucoceka okulungileyo kodwa ukuxhathisa ubushushu.I-viscosity inokuvela kwi-1 gram yefilimu ekhuselayo ukuya kwi-3000gram ye-VHB series tape.Ngokuqhelekileyo, ukuphakama kwe-viscosity, kubi kakhulu ukumelana nobushushu.Ukushisa kweglasi yokutshintsha kwe-adhesive ye-acrylic malunga ne-200 degrees, imilo ye-adhesive ye-acrylic ngaphezu kwe-200 degrees itshintshile, kwaye i-viscosity iphantsi kakhulu.Emva kokugqiba ukugquma, kufuneka iphiliswe kwaye ivuthwe kwi-40 ° C kwiiyure ezingama-48.Ixesha lokuphiliswa kunye nelokukhula lihlukile ehlotyeni nasebusika, iintsuku ezi-3-4 ehlotyeni kwaye malunga neveki enye ebusika.
Ukumelana nobushushu obuphantsi sisiphene sohlobo lwe-adhesive ye-acrylic.Nangona kunjalo, umzi-mveliso weglue wenze uphando oluninzi ukulungisa iglu.Okwangoku, iphuhlise ukumelana nobushushu obungama-250 degrees kunye ne-viscosity ye-7-8N ye-adhesive ye-acrylic ephezulu.itheyiphu yobushushu.
Okwesithathu, ngokwesakhiwo esahlukileyo somaleko, ubushushu obuphezulu bunokwahlulwa njengasezantsi
- 1. Itheyiphu yecala elinye lobushushu obuphezulu
Iteyiphu yecala elinye iqulathe isithwali esifana nefilimu yePolyimide, ifilimu yePolyester, ilaphu leglasi, ilaphu leglasi yeTeflon okanye ifilimu ye-PTEFE kwaye igqunywe ngomaleko omnye wokuncamathelisa njenge-silicone yokuncamathelisa okanye i-acrylic encamathelayo.
- 2. Iteyiphu yecala elinye kunye nefilimu yokukhulula
Iteyiphu yecala elinye kunye nefilimu yokukhululwa sebenzisa ifilimu njengesithwala esiqatywe nge-silicone okanye i-acrylic adhesive kwaye idibanise nefilimu yokukhululwa ukukhusela icala elincamathelayo.
- 3. Iteyiphu yecala eliphindwe kabini kunye nefilimu enye yokukhulula
Iteyiphu esecaleni ephindwe kabini enomaleko omnye wokukhutshwa kwefilimu sebenzisa ifilimu njengesithwala icala eliphindwe kabini eliqatywe ngesilicone okanye i-acrylic adhesive kwaye kudityaniswe nefilimu yokukhupha.
- 4. Itheyiphu yesantshi emacala amabini enefilim yokukhulula
Iteyiphu esecaleni ephindwe kabini enefilimu encamathelayo encamathelayo isebenzisa ifilimu njengesithwala esincamathelayo esincamathele kabini kwaye idityaniswe nefilimu encamathelayo yomaleko emibini, umaleko omnye ukuya kwicala lokuncamathelisa elisecaleni, omnye umaleko ukuya ngasemva wokuncamathelisa, usetyenziswa ikakhulu ekusikeni ukufa.
Ngaphezulu luluhlu lweeteyiphu zobushushu obuphezulu ngokweendlela ezahlukeneyo.Ngeenkcukacha ezithe vetshe kunye nengcaciso, ncedaCofa apha.Ubuya kufumana ngakumbiiiteyiphu ezikwaziyo ukumelana nobushushukwayekufa ukusika isisombululongokwesicelo sakho apha kwi-GBS.
