Ukushisa-kokuqhuba ingcina: izakhiwo kanye isicelo, ukukhiqizwa

Iqiniso lokuthi glue ezinjalo, bayazi konke. Le into engazwakali kwakudingeka ukuxhumana Friend izakhi ezimbili noma ngaphezulu bodwa. Nokho, kuye ngohlobo kunenze nisondelane ezisetshenziswa kudingeka ifomu ezinye glue: PVA kufanelekile amakhadibhodi, isikhumba, ingilazi, nendwangu; "Moment" ngeke abe nesibopho metal, epulasitiki, iraba, ukhuni, nokunye. D. Kodwa lokho okufundile ukufakwa izakhi ukushisa-ekususeni, ezifana radiators, isibonelo?

Ukuze usebenze nabo kudinga isixazululo eziklanyelwe ezingasetshenziswa ukumelana okushisa aphezulu possesses nezinye izici ezibalulekile. It waba ingcina thermally conductive.

Kungani udinga?

Ukuze uthole buhlobo buhlale buqinile, high, kwakungekho ukuhlanekezela noma okweqile izingxenye ngesikhathi inhlangano, kubalulekile ukuhlinzeka ukushisa ukususwa kusukela izakhi, okuyinto ashisise ngesikhatsi kokuhlinzwa. Nge lo msebenzi ukubhekana kahle ingcina thermally conductive. Ukuze radiators, LED nezinye electronics ezidinga ukufakwa, lesi sisombululo kumane Irreplaceable. Isebenza phezu ububanzi lokushisa ububanzi. Kulokhu, isici esibalulekile akunakudluliswa anobuthi isixazululo glue, ukuze ukwazi ungesabi ukuyisebenzisa yokuhlala.

Thermally glue conductive "osabalalayo"

Lokhu ingcina ithandwa kakhulu nge thermally conductive ingcina umsebenzi. Lokhu kungenxa eziningi eziwusizo yesixazululo. Okokuqala, kokokunamathisela olumelana ithonya izinto ezifana isenzo kokukhanya kwelanga, eshintsha ezimweni zangaphandle kwemvelo, umswakama high (umswakama namanzi). Okwesibili, ikhambi kunenze nisondelane has a viscosity okusezingeni eliphezulu futhi inikeza ngezinga eliphezulu adhesion izinto ezifana ngengilazi, epulasitiki, Ceramic noma metal. Okwesithathu, inhlaka "osabalalayo" unamandla kakhulu (ikhasi ka 2.3 MPA noma ngaphezulu). Ngaphezu kwalokho, ngokusebenzisa le ingcina, awukwazi ukhathazeke okuvela okungenzeka nokugqwala on aluminium, steel nesiliva imininingwane.

I ingcina has high conductivity ezishisayo futhi amelana omkhulu ngempela lokushisa ukuhluka. Umsebenzi wakhe ndawo ku uhla kusuka degree angu -60 300 Celsius!

Indlela yokusebenzisa?

Isinyathelo sokuqala ukuhlanza futhi degrease ebusweni okuzokwenza ozofakwa ingcina thermally conductive. Lokhu kungenziwa nge acetone, uphethiloli noma utshwala. Ngokulandelayo, ebusweni ukulungele yesixazululo ingcina isicelo ngasinye 1 isentimitha square okungenani 1 ml. Yekuchumana benzelwe futhi aboshezelwa cishe 20-25 imizuzu. Khona-ke udinga isikhathi esithile, okungukuthi 24 amahora ukunikeza izakhi ngokuqinile. Ekupheleni kosuku, ziphathwe lento ingcina ingasetshenziswa.

He is nje esisemqoka ezimweni lapho akunakwenzeka ukusebenzisa nokunamathisela ukushisa ukumelana futhi substrate. Ungathenga kuyo radiators yisiphi isitolo pravkticheski, kodwa uma kungekho anjalo, kungenzeka ukuba izgtovit thermally conductive ingcina ngesandla. Yiqiniso, ilula kangaka, kodwa ngempela ngempela yini.

Indlela yokwenza i-glue?

Ukuze wenze lokhu, lungiselela glycerol usimende. Kuyinto eqinile ngempela futhi livikela ngezinhlobo ezahlukene ukucindezeleka, izinga lokushisa lokusebenza ifinyelela degrees 250. Sidinga glycerol emzimbeni: amanzi ukususa glycerol kumele ukufuthelana degrees 200. Izidingo ezifanayo kwenziwe luyibhuqu lwezinyawo oxide phambili (Empunga degrees 300). Bobabili mass selehlile futhi iphathwa - uzoba unamathisele, ukuvumelana sifana inhlama hhayi elukhuni kakhulu.

Manje into esemqoka - ukuba athathe isinyathelo ngokushesha. Ukuze isicelo glue okuzenzela uzobe imizuzu mayelana 15-20, okwathi ngemva kwalokho mass ingcina uye lukhuni. Isilinganiso glycerol futhi oxide phambili kanje: 25 ml 100 amagremu futhi ngokulandelana.

isiphetho

Njengoba ubona, a ingcina thermally conductive iyithuluzi elibalulekile lapho esebenza radiators, lapho ukulungisa processor Transistor, ngoba LED obandayo nezinye electronics. Ngokusho impahla yayo, ungcono kakhulu unama thermally conductive, okungezona ezinobuthi futhi linamandla kakhulu. Kulokhu, kukhona i-glue esinjalo kubaluleke ngempela ashibhe - ishubhu elilodwa kuyokulahlekisela esifundeni $ 100. nalokho Kufaka ukhonza isipetu (2 ml). Uma uneminye ingcina ngokweqile emva kokuphothulwa umsebenzi, khona-ke nje ukuvala isipetu nilishiye libe izidingo zesikhathi esizayo. Le isixazululo ingcina isikhathi eside akusho wome, okungelinye of inzuzo yakhe undoubted.
