A zafi-GUDANAR m: dũkiyarsu da kuma aikace-aikace, samarwa

Gaskiyar cewa irin wannan manne, sun san kome da kome. Wannan m abu da ake bukata domin wani m dangane biyu ko fiye da abubuwa a tsakãninsu. Duk da haka, dangane da irin bonding kayan amfani bukatar wasu manne form: PVA ne dace da kwali, fata, da gilashi, da kuma zane. "Lokacin" Za haduwa karfe, roba, roba, da itace, da kuma sauransu. D. Amma abin da abu don amfani ga shigarwa na zafi-cire abubuwa, kamar radiators, misali?

Don aiki tare da su na bukatar musamman tsara bayani wanda zai iya tsayayya high yanayin zafi da kuma mallaka sauran muhimmanci halaye. Yana ne irin wannan thermally conductive m.

Don me kuke bukatar?

Domin samun wani karfi bond, kuma high quality, babu murdiya ko zafi fiye da kima daga sassa a lokacin taron, wajibi ne a samar da zafi kau daga abubuwa, wanda zafi sama a lokacin aiki. Tare da wannan aiki daidai jimre thermally conductive m. Domin radiators, LEDs da sauran lantarki bukata kafuwa, wannan bayani ne kawai irreplaceable. Yana aiki a kan wani m zazzabi range. A wannan yanayin, da muhimmanci alama ne da ba mai guba manne bayani, don haka ba za ka iya ji tsoro don amfani da shi a cikin wani mazauni.

Thermally conductive manne "radial"

Wannan m ne mafi m tare da wani thermally conductive m aiki. Wannan shi ne saboda da dama abũbuwan amfãni daga cikin bayani. Da fari dai, m ne resistant zuwa rinjayar dalilai kamar mataki na hasken rana, ya canjãwa a waje muhalli yanayi, high zafi (danshi da kuma ruwa resistant). Abu na biyu, da bonding bayani yana da babban danko da kuma samar da wani babban mataki na mannewa na kayan kamar gilashi, roba, yumbu ko karfe. Uku, da manne "radial" ne sosai karfi (da kwasfa na 2.3 MPa ko fiye). Bugu da kari, yin amfani da wannan m, ba za ka iya damu game da zai yiwu ya faru na tsatsa a kan aluminum, karfe da azurfa bayani.

A m yana da high thermal watsin da kuma shi ne resistant zuwa gaske babbar zazzabi bambancin. Aikinsa yanki ne a cikin kewayon daga -60 zuwa 300 digiri Celsius!

Yadda za a yi amfani da?

A mataki na farko shi ne domin tsabtace kuma degrease surface wadda za a iya amfani da wani thermally conductive m. Wannan za a iya yi tare da acetone, fetur, ko barasa. Next, cikin shirye surface na m bayani amfani da 1 square santimita a mafi 1 ml. Details ana gyarawa da kuma clamped da kimanin 20-25 minti. Sa'an nan kuma ka bukatar wani lokaci, wato 24 hours don samar da wani m riko abubuwa. Bayan wata rana, bi da tare da m abu za a iya amfani da su.

Shĩ ne kawai ba makawa a lokuta inda shi ne ba zai yiwu a yi amfani da zafi-resistant manna da substrate. Za ka iya saya da shi a cikin wani kantin sayar da pravkticheski radiators, amma idan babu irin wannan, yana yiwuwa ya izgtovit thermally conductive m da hannu. Wannan, ba shakka, ba haka ba ne mai sauki, amma quite real.

Yadda za a yi manne?

Don yin wannan, shirya glycerol sumunti. Yana da quite karfi da kuma resistant zuwa iri-iri na danniya, da zafin aiki ya kai 250 digiri. Muna bukatar dehydrated glycerol: ruwa cire glycerol dole ne a mai tsanani zuwa 200 digiri. A wannan bukatun da za a yi tare da foda na gubar oxide (Gray zuwa 300 digiri). Dukansu taro sanyaya kuma bi - za ku ji da manna, da daidaito yayi kama da ba sosai m kullu.

Yanzu babban abu - don aiki da sauri. Domin aikace-aikace na gida manne za ku zama game 15-20 minti, bayan da m taro ya taurare. A rabo daga glycerol da gubar oxide kamar haka: 25 ml da kuma 100 grams bi da bi.

Kamar yadda ka gani, a thermally conductive m ne ba makawa kayan aiki a lõkacin da aiki tare da radiators, a lokacin da kayyade a transistor processor, don hawa LEDs da sauran lantarki. A cewar ta Properties, shi ne mafifici ga thermally conductive manna, wadanda ba mai guba da kuma sosai resistant. A wannan yanayin, akwai irin wannan manne ne quite m - daya tube zai kudin ka, a yankin na $ 100. Hade cikinta hidima sirinji (2 ml). Idan kana da wani wuce haddi da m bayan kammala aikin, to, kawai rufe sirinji da kuma bar shi, domin nan gaba bukatun. Wannan m bayani na dogon lokaci ba ya bushe up, wanda shi ne wani ya undoubted amfani.
