Bambanci tsakanin thermal silica gel da thermal man shafawa

1. Menene halaye na thermal silica gel (thermal potting manne)?

Silicone mai ɗorewa na thermally kuma ana kiransa mannen tukunyar tukunyar zafi ko mannen RTV mai zafi.Yana da ƙarancin danko mai ɗaukar wuta mai juzu'i biyu ƙari nau'in siliki mai ɗaukar zafi mai ɗaukar manne tukwane.Ana iya warkewa a yanayin zafi ko zafi.Mafi girman zafin jiki, saurin magani.ƙwarewa.Babban bambanci daga man shafawa na siliki na thermal shine cewa ana iya warkewar siliki na thermal kuma yana da wasu kaddarorin mannewa.

Gel silica na thermally conductive (thermally conductive potting manne) wani nau'in roba ne na silicone, wanda ke cikin robar ruwa na ɓarnawar yanayin zafin ɗaki mai kashi ɗaya.Da zarar an fallasa shi zuwa iska, silane monomers da ke cikinsa suna tattarawa don samar da tsarin hanyar sadarwa, tsarin yana haɗe-haɗe, ba za a iya narkewa da narkewa ba, yana da roba, ya zama roba, kuma yana manne da abubuwa a lokaci guda.Its thermal conductivity ya dan kadan sama da na talakawa roba, amma yana da yawa kasa da na thermal conductive man siliki, kuma da zarar warke, da wuya a raba bonded abubuwa.

2. Menene halayen thermal maiko
Thermally conductive silicone man shafawa yawanci kuma ake kira "thermally conductive manna", "silicon manna", thermally conductive silicone man shafawa wani nau'i ne na high thermal conductivity insulating silicone abu, ba ya warkewa, kuma zai iya kula da yanayin man shafawa na dogon lokaci. a zazzabi na -50°C-+230°C thermal conductive abu.Ba wai kawai yana da ingantaccen rufin lantarki ba, har ma yana da kyakkyawan yanayin zafi, kuma a lokaci guda yana da ƙarancin rabuwar mai (yana nufin sifili), tsayi da ƙarancin zafin jiki, juriya na ruwa, juriya na ozone, da juriya na tsufa.

Yana za a iya yadu shafi daban-daban lantarki kayayyakin, da lamba surface tsakanin dumama abubuwa (ikon shambura, silicon sarrafa rectifiers, lantarki dumama stacks, da dai sauransu) The rawar da zafi canja wurin matsakaici da danshi-hujja, ƙura-hujja, lalata-hujja. , girgiza-hujja da sauran kaddarorin.

Ya dace da rufin ƙasa ko gabaɗaya tukunyar na'urorin microwave daban-daban kamar sadarwa ta microwave, kayan watsawa microwave, samar da wutar lantarki na musamman, da ƙarfin wutar lantarki da aka daidaita.Irin wannan nau'in siliki yana ba da kyakkyawan yanayin zafi don abubuwan lantarki waɗanda ke haifar da zafi.Kamar su: transistor, taron CPU, thermistors, na'urori masu auna zafin jiki, na'urorin lantarki na mota, firiji na mota, na'urorin wutar lantarki, shugabannin firinta, da sauransu.

3. Kamanceceniya da bambance-bambance tsakanin thermal silica gel da thermal man shafawa
Abin da suke da shi: dukkansu suna da tasirin zafi da kuma rufi, kuma duk kayan aikin thermal ne.

bambanci:

Silicone mai ɗorewa na thermal (thermally conductive potting manne): m (da zarar makale, da wuya a cire,

Don haka, ana amfani da shi galibi a lokatai da ake buƙatar haɗin kai na lokaci ɗaya kawai.Yana da haske, yana narke a babban zafin jiki (ruwa mai ɗorewa), ƙarfafawa (wanda aka fallasa) a ƙananan zafin jiki, ba zai iya narke da narke ba, kuma yana da roba.

Thermally conductive silicone man shafawa (thermally conductive manna): Adsorptive, non-stick, manna Semi-ruwa, mara maras tabbas, mara curing (ba ya kauri a low zazzabi, kuma ba ya zama bakin ciki a high zafin jiki).

4. Iyakar aikace-aikace

Idan aka kwatanta da gel silica, aikace-aikacen man shafawa na silicone ya fi yawa.Yawancin samfuran masana'antu da na lantarki suna amfani da man shafawa na siliki na zafi inda ake buƙatar zubar da zafi.

Bugu da ƙari, akwai nau'ikan man shafawa na silicone da yawa, kuma mutane suna ƙara wasu "ƙazanta" zuwa man shafawa na siliki mai ɗaukar zafi mai tsafta don haɓaka haɓakar yanayin zafi.

Wadannan najasa sune graphite foda, aluminum foda, jan karfe da sauransu.

Man shafawa na siliki mai tsafta tsantsa fari ne mai ruwan madara, man silicone ɗin da aka haɗe da graphite duhu ne, man silicone ɗin da aka haɗe da foda aluminium yana da launin toka kuma mai sheki, man silicone ɗin da aka haɗe da foda na jan karfe yana ɗan rawaya.
