Isidingo seglue yokuncamathelisa kwimbiza yombane

Ukubumba kubandakanya ukuzaliswa okwenziwa kusetyenziswa i-adhesive okanye i-potting compound. Xa oku kusenziwa, amacandelo adla ngokuba kwindawo yokuphumla okanye kwizindlu ekufuneka zizaliswe ngokuncamathelisa.

Kutheni ifuneka

Iibhodi zeesekethe zineenxalenye ezincinci ezincinci ezinobuthathaka kakhulu. Ezi ziquka ii-diode, ii-transistors, kunye ne-microchips. Kukho imfuneko yokubakhusela kumswakama obangela iisekethe ezimfutshane kwinkqubo. Kukho imfuneko yokukhuselwa kweekhemikhali ngokunjalo, njengoko inokuhlasela okanye idle amacandelo. Impembelelo, ukungcangcazela, kunye nomothuko wobushushu nazo kufuneka zikhuselwe. Oku kungenxa yokuba banokukhupha izixhobo ezinikezela isixhobo okanye inkqubo engenamsebenzi.

Kukho iimeko ezininzi apho i-potting electronics yenza kube nzima ukukopa okanye ukuhlola i-circuitry. Oku kwenza ukuba abafundi bamakhadi kunye neetshiphusi ezikrelekrele kube nzima ukuba abaphuli-mthetho bafikelele kwaye bazibhuqe. Oku ngakumbi xa i-potting iba yinxalenye yezixhobo kwaye ayikwazi ukususwa ngaphandle kokonakalisa iteknoloji.

Izincamathelisi ezisetyenzisiweyo

Xa ubeka imbiza kwizicelo ezahlukeneyo, kusoloko kungcono ukusebenzisa i-adhesives ye-viscosity ephantsi. Lukhetho olukhethiweyo. Oku kungenxa yokuba bagcwalisa amacandelo ngcono ngelixa benciphisa ukuvalelwa kwamaqamza omoya.

Ii-epoxies ezilungisiweyo kunye nee-epoxies ezinamacala amabini zezinye zezona zikhetho ezilungileyo. I-Silicones kunye ne-polyurethane nazo zikhetho ezilungileyo. Nazi Izinto zokuncamathelisa UV ezinokuthi zisetyenziswe ukwenza unyango olukhawulezayo lusebenze, kwaye azidingi naluphi na ukuxuba. Imimandla yomthunzi, kunye nobunzulu obulinganiselweyo, ngokuqhelekileyo ibonisa ukuba ayinakufaneleka. Nangona kunjalo, ezinye izinto zokuncamathelisa ze-UV zineendlela zokunyanga zesibini ezivumela ukunyanga ngokupheleleyo, nakwimimandla yomthunzi.

iingqalelo

Xa ukhetha i-adhesives oza kuyisebenzisa kwi-potting, kukho iingcamango ezahlukeneyo zokwenza. Ezi ziquka:

• Umthamo we-receptacle: ukuba ufuna ukuzalisa umthamo omkhulu, kufuneka uqwalasele i-exotherm ye-adhesive njengoko iphilisa. Kungcono ukhethe izinto ezincamathelayo ezicothayo kuba zinethuba elincinane lobushushu njengoko zinyanga.
• Iimpawu zokuhamba kunye ne-viscosity: kuya kufuneka unqume ukuba imbiza inokuhamba njengoko kufuneka igqume eyona nxalenye incinci kunye neyona intsonkothileyo. Kufuneka kwakhona uqikelele ukuba unokukuthintela ukuvalelwa komoya kunye namaqamza omoya.
• Kufuneka uqikelele ukuba kufuneka unyango ngokukhawuleza kangakanani. Oku kunceda ukugqiba uhlobo lwekhompawundi oza kuyisebenzisa
• I-substrate imathiriyeli esetyenziselwa ukwenza i-receptacle kufuneka imiselwe ngokunjalo. Kubalulekile ukuqinisekisa ukunamathela okulungileyo kumaphethelo.
• Inkqubo yesicelo kufuneka imiselwe nayo. Kufuneka ucinge ukuba kuya kwenziwa ngesandla okanye ngokuzenzekelayo. Kwakhona, jonga ukulunga kokusebenzisa iimveliso ezinamacala amabini.
• Kwakhona, misela umbala okanye opaqueness ye-adhesive njengoko kufuneka. Kukho iimeko apho ufuna iziphumo ezicacileyo, ngelixa kwezinye, i-opaque compound yeyona ilungileyo.
• Ubulukhuni bokuncamathelisa bubalulekile njengoko bunciphisa imingcipheko yokuphazamisa. Oku kuthetha ukuba uxinzelelo oluncinci kumacandelo ekuncipheni kwe-thermal kunye nokwandiswa.
• Iindleko nazo kufuneka zimiselwe. Akusoloko kububulumko ukukhetha eyona ndlela inexabiso eliphantsi. Fumana into ekumgangatho ophezulu kwaye ekwaziyo ukuphatha umsebenzi okhoyo.

Kwi-DeepMaterial, sinezona zinto zincamathelayo kwimbiza ukuze uzifunde. Ngombono ochanekileyo, kuya kufuneka ukwazi ukufumana iziphumo ezilungileyo ekupheleni kosuku. Ukusebenza ngezona zilungileyo kukunika ithuba elingcono lokufumana izisombululo ezomeleleyo.
