Itandukaniro riri hagati yubushyuhe bwa silika gel hamwe namavuta yubushyuhe

1. Ni ibihe bintu biranga gelika ya silika yumuriro (glue potting)?

Silicone yubushuhe bwa silicone mubisanzwe nanone yitwa kole yubushyuhe bwo kubumba cyangwa kole ya RTV.Nibintu bike-viscosity flame-retardant ibice bibiri byongeweho ubwoko bwa silicone ubushyuhe butwara inkono.Irashobora gukira ubushyuhe bwicyumba cyangwa gushyuha.Ubushyuhe buri hejuru, niko gukira byihuse.umwihariko.Itandukaniro rinini ryamavuta ya silicone yumuriro nuko silicone yumuriro ishobora gukira kandi ifite ibintu bifatika.

Ubushyuhe bwa silika gelike yubushyuhe (koleji yubushyuhe bwo kubumba) ni ubwoko bwa reberi ya silicone, ikaba ari reberi yamazi yubushyuhe bwicyumba kimwe.Bimaze guhura nikirere, monomers ya silane muri yo ihurira hamwe kugirango ibe imiterere y'urusobe, sisitemu irahuzwa, ntishobora gushonga no gushonga, iroroshye, ihinduka reberi, kandi ifatira kubintu icyarimwe.Ubushuhe bwabwo bwumuriro buri hejuru gato ugereranije nubwa reberi isanzwe, ariko ni munsi cyane ugereranije namavuta ya silicone ya silicone yumuriro, kandi iyo imaze gukira, biragoye gutandukanya ibintu bihujwe.

2. Ni ibihe bintu biranga amavuta yubushyuhe?
Amavuta ya silicone yimyanya yubushyuhe ubusanzwe nanone yitwa "paste yimyanya yubushyuhe", "silicon paste", amavuta ya silicone yimyanya yubushyuhe nubwoko bwinshi bwumuriro mwinshi utanga ibikoresho bya silicone, ntabwo bikiza, kandi birashobora gukomeza imiterere yamavuta mugihe kirekire. ku bushyuhe bwa -50 ° C- + 230 ° C ibikoresho bitwara ubushyuhe.Ntabwo ifite amashanyarazi meza cyane, ahubwo ifite nubushuhe buhebuje bwumuriro, kandi mugihe kimwe itandukanya amavuta make (ikunda kuri zeru), kurwanya ubushyuhe buke nubushyuhe buke, kurwanya amazi, kurwanya ozone, hamwe no kurwanya gusaza kwikirere.

Irashobora gukoreshwa cyane mubicuruzwa bitandukanye bya elegitoroniki, hamwe nubuso bwo guhuza hagati yubushyuhe (umuyoboro wamashanyarazi, ibyuma bikoreshwa na silikoni igenzurwa, ibyuma bishyushya amashanyarazi, nibindi) , guhungabana-nibindi bintu.

Irakwiriye gutwikirwa hejuru cyangwa kubumba muri rusange ibikoresho bitandukanye bya microwave nkitumanaho rya microwave, ibikoresho byohereza microwave, amashanyarazi yihariye ya microwave, hamwe na voltage ihagaze neza.Ubu bwoko bwibikoresho bya silicon butanga ubushyuhe bwiza bwibikoresho bya elegitoronike bitanga ubushyuhe.Nka: tristoriste, inteko ya CPU, thermistors, ibyuma byubushyuhe, ibikoresho bya elegitoroniki yimodoka, firigo yimodoka, module yingufu, imitwe ya printer, nibindi.

3. Ibisa nibitandukaniro hagati yubushyuhe bwa silika gel hamwe namavuta yubushyuhe
Icyo bahurizaho: bose bafite ubushyuhe bwumuriro no kubika, kandi byose nibikoresho byubushyuhe.

itandukaniro:

Silicone itwara ubushyuhe (kole yubushyuhe bwo kubumba): ifatanye (imaze gukomera, kuyikuramo,

Kubwibyo, ikoreshwa cyane mubihe aho bisabwa guhuza inshuro imwe gusa.Irasobanutse, ishonga ku bushyuhe bwo hejuru (amazi ya viscous), irakomera (igaragara) ku bushyuhe buke, ntishobora gushonga no gushonga, kandi iroroshye.

Amavuta ya silicone yamavuta yubushyuhe (paste yubushyuhe)

4. Ingano yo gusaba

Ugereranije na silika gel, gukoresha amavuta ya silicone ni byinshi.Ibicuruzwa byinshi byinganda na elegitoronike bifashisha amavuta ya silicone yumuriro aho bikenewe gukwirakwizwa.

Byongeye kandi, hari ubwoko bwinshi bwamavuta ya silicone, kandi abantu bongeraho "umwanda" mumavuta meza ya silicone yumuriro wa silicone kugirango bongere ubushyuhe bwayo.

Iyi myanda ni ifu ya grafite, ifu ya aluminium, ifu yumuringa nibindi.

Amavuta meza ya silicone yera yera yuzuye amata, amavuta ya silicone avanze na grafite yijimye mwijimye, amavuta ya silicone avanze nifu ya aluminiyumu ni imvi kandi irabagirana, naho amavuta ya silicone avanze nifu yumuringa hari umuhondo.
