Lub tshav kub-kev nplaum: zog thiab daim ntawv thov, ntau lawm

Qhov tseeb hais tias xws li ib tug kua nplaum, lawv paub txhua yam. Qhov no nplaum tshuaj uas yuav tsum tau rau ib tug ceev kev twb kev txuas ntawm ob los yog ntau tshaj cov ntsiab ntawm lawv tus kheej. Txawm li cas los, nyob ntawm seb lub hom tsevneeg khoom siv xav tau ib co kua nplaum daim ntawv: PVA yog haum rau cov duab los qhia, tawv tsiaj, iav, thiab daim ntaub; "Caij" yuav bond hlau, yas, roj hmab, ntoo, thiab hais txog. D. Tab sis dab tsi cov khoom siv rau lub installation ntawm tshav kub-tshem hais, xws li dab, piv txwv li?

Mus ua hauj lwm nrog lawv yuav tsum tau tshwj xeeb uas tsim tshuaj uas muaj peev xwm mas siab kub thiab muaj lwm yam tseem ceeb cov yam ntxwv. Nws yog xws li ib tug thermally conductive nplaum.

Vim li cas koj xav tau?

Nyob rau hauv thiaj li yuav tau ib tug muaj zog daim ntawv cog lus, thiab siab zoo, muaj tsis muaj distortion los yog overheating ntawm qhov chaw thaum lub sij hawm los ua ke, nws yog tsim nyog los muab kub tshem tawm los ntawm lub ntsiab, uas sov li thaum lub sij hawm lub lag luam. Nrog rau qhov no ua hauj lwm txig tiv thermally conductive nplaum. Rau dab, LEDs thiab lwm yam electronics tau installation, cov tshuaj no yog tsuas irreplaceable. Nws ua hauj lwm ntau tshaj ib tug ntau ntau yam kub. Nyob rau hauv cov ntaub ntawv no, qhov tseem ceeb feature yog uas tsis yog-tshuaj lom lo lus teb, li ntawd, koj yuav tsis txhob ntshai siv nws nyob rau hauv ib tug lub tsev.

Thermally conductive lo "Radial"

Qhov no nplaum yog lub nrov tshaj plaws nrog ib tug thermally conductive nplaum muaj nuj nqi. Qhov no yog vim ib tug xov tooj ntawm zoo ntawm cov tshuaj. Firstly, lub nplaum yog resistant rau tus ntawm yam tseem ceeb xws li qhov kev txiav txim ntawm tshav ntuj, hloov nyob rau hauv lwm ib puag ncig tej yam kev mob, cov pwm (dej thiab dej resistant). Secondly, lub ua ke tov muaj ib tug high viscosity thiab muab ib tug high degree ntawm adhesion ntawm cov ntaub ntawv xws li lub khob, yas, tej hub los yog txawm hlau. Peb, cov kua nplaum "Radial" no muaj zog heev (lub tev ntawm 2.3 MPa los yog ntau tshaj). Nyob rau hauv tas li ntawd, siv no nplaum, koj muaj peev xwm tsis txhawj txog qhov tau tshwm sim los ntawm tus kab xeb rau txhuas, hlau thiab nyiaj kom paub meej.

Cov nplaum muaj siab thermal conductivity thiab yog resistant mus tiag tiag lossis loj kub variations. Nws ua hauj lwm hauv cheeb tsam yog nyob rau hauv ntau ntawm -60 mus rau 300 degrees Celsius!

Yuav ua li cas siv tau?

Thawj kauj ruam yog los ntxuav thiab degrease qhov chaw uas yuav tsum muaj ntaub ntawv mus rau ib tug thermally conductive nplaum. Qhov no yuav ua tau nrog acetone, roj av los yog dej cawv. Tom ntej no, lub npaj nto ntawm lub nplaum tov thov ib 1 square centimeter nyob 1 ml. Paub meej yog tsau thiab clamped los ntawm kwv yees li 20-25 feeb. Ces koj xav tau ib co sij hawm, namely 24 teev los muab ib tug tuav khov ntsiab. Tom qab ib hnub, kho nrog nplaum yam khoom yuav siv tau.

Nws yog tsuas indispensable nyob rau hauv tus neeg mob qhov twg nws yog tsis tau mus siv thaum tshav kub kub-resistant muab tshuaj txhuam thiab lub substrate. Koj muaj peev xwm yuav nws nyob rau hauv tej khw pravkticheski dab, tab sis thaum tsis muaj xws li, nws yog ua tau rau izgtovit thermally conductive nplaum los ntawm txhais tes. Qhov no, ntawm chav kawm, yog tsis yooj yim li, tab sis heev tiag tiag.

Yuav ua li cas yuav ua rau cov kua nplaum?

Ua li no, npaj glycerol xis mas. Nws yog ib heev muaj zog thiab resistant rau ntau hom ntawm kev nyuaj siab, lub khiav hauj lwm kub nce mus txog 250 degrees. Peb yuav tsum tau lub cev qhuav dej glycerol: dej kom tshem tawm glycerol yuav tsum tau rhuab rau 200 degrees. Cov tib xav tau kev pab yuav tsum tau ua nrog rau cov hmoov txhuas oxide (Grey mus rau 300 degrees). Ob leeg loj txias thiab kho - koj yuav muaj ib tug muab tshuaj txhuam, lub taub hau tsa ib tug tsis heev txhav khob noom cookie.

Tam sim no lub ntsiab tshaj plaws - mus ua sai sai. Rau daim ntawv thov ntawm qhob lo koj yuav tsum txog 15-20 feeb, tom qab uas lub nplaum loj tau hardened. Qhov ratio ntawm glycerol thiab txhuas oxide raws li nram no: 25 ml thiab 100 grams feem.

xaus

Raws li koj tau pom, ib tug thermally conductive nplaum yog ib qho tseem ceeb lub cuab tam thaum ua hauj lwm nrog dab, thaum kho ib tug transistor processor, rau mounting LEDs thiab lwm yam electronics. Raws li nws cov khoom, nws yog superior rau lub thermally conductive muab tshuaj txhuam, uas tsis yog-tshuaj lom thiab mas resistant. Nyob rau hauv cov ntaub ntawv no, muaj xws li ib tug kua nplaum yog heev pheej yig - ib tug raj yuav raug nqi koj nyob rau hauv lub cheeb tsam ntawm $ 100. Muaj thereto ua hauj lwm pab koob txhaj (2 mL). Yog hais tias koj muaj lus tshaj nplaum tom qab kawm tiav ntawm lub chaw ua hauj lwm, ces cia li kaw lub koob txhaj thiab cia nws rau yav tom ntej xav tau kev pab. Qhov no nplaum tov rau ib ntev lub sij hawm tsis qhuav li, uas yog ib tug ntawm nws undoubted kom zoo dua.
