Imbonerahamwe yimikorere yibikoresho bya silicone ifuro, agaciro gasa nkudafatika k "" imbaraga zo kurwanya "akenshi birengagizwa nababigize umwuga -. Nyamara, kuri buri injeniyeri ya elegitoroniki, uwashushanyije ibicuruzwa, hamwe nabakozi bashinzwe kugenzura ubuziranenge, ntabwo ari umubare woroheje gusa, ahubwo ni ikintu cyibanze cyubugingo kigena ibicuruzwa by’umutekano w’amashanyarazi kandi birebire - igihe cyo kwizerwa.
Nkuko ibikorwa biganisha kuri Sanpu Silicone, twakira ibibazo bya buri munsi kubakiriya bijyanye no guhitamo ibikoresho. Uyu munsi, ndashaka kuganira nabagenzi binganda impamvu 'kurwanya ingano' ari ngombwa 'metric ikomeye' tugomba kubanza gusobanura mubitumanaho byabakiriya.
一. Kurwanya amajwi ni iki? Igisobanuro cyingenzi cyingenzi
Gutangira, reka dusobanure igitekerezo cyibanze. Kurwanya amajwi (Vρ), mubisanzwe bipimwa muri Ω · cm, bisobanura ibintu byihariye birwanya imbaraga z'amashanyarazi zinyura mu mubare w'imbere. Uyu mutungo wimbere ukomeza kuba utitaye kumiterere yibikoresho cyangwa ubunini.
Ikigereranyo cyoroshye:
Tekereza ifuro ya silicone nka sponge.
Ijwi ryinshi rirwanya (urugero . 10 ^ 15 Ω · cm): nka "sponge" isukuye, ikigezweho kiragoye cyane kwinjira.
Umuvuduko muke (urugero . 10 ^ 3 Ω · cm): nka "sponge ikora" yashizwe mumazi yumunyu, umuyoboro urashobora kunyuramo byoroshye.
Gufunga - selile silicone ifuro ibikoresho, bikoreshwa cyane murwego rwa elegitoroniki, turashaka uburyo bwo guhangana cyane cyane, kuburyo bihinduka "sponge" nziza.
2. Kuki ari ngombwa cyane? Isesengura ryimikorere itatu yibanze
1
Uru nirwo ruhare rutaziguye kandi rwibanze rwo kurwanya amajwi. Iyo ibicuruzwa byawe birimo guhererekanya ingufu cyangwa guhanahana ibimenyetso, abayobora bafite ubushobozi butandukanye barashobora kuba milimetero - intera iri hagati yabo.
Hejuru - voltage ikoreshwa: Mubipaki ya bateri hamwe nu bikoresho bigenzura ibikoresho bya elegitoronike yimodoka nshya, voltage ikora irashobora kugera kuri volt amagana. Ibisohoka byose biva mu gaseke cyangwa impeta zifunga bishobora gutera sisitemu kunanirwa, gushyuha cyane, cyangwa guhungabanya umutekano. Ibikoresho byinshi - birwanya ubukana bwa silicone ifuro itanga inzitizi ya mbere ikomeye yo gukumira muri ibi bidukikije.
Umuvuduko muke wibintu byoroshye: Ndetse no mumashanyarazi make ya terefone igendanwa nibikoresho byambarwa, kunanirwa kwizana ryibikoresho nabyo bizatera imiyoboro ngufi hamwe no gutwika ibice, bikaviramo kwangirika bidasubirwaho.
Umwanzuro: Umubare munini wo kurwanya agaciro niwo musingi wibicuruzwa kugirango utsinde ibyemezo byumutekano (nka UL na CE) kandi urebe umutekano wabakoresha.
2. "Stabilisateur" yuburinganire bwibimenyetso: kwemeza amakuru neza
Mubihe bigezweho - inshuro nyinshi kandi ibikoresho byitumanaho byihuta - (nka sitasiyo fatizo ya 5G na seriveri), ibikoresho bya silicone ifuro akenshi bikoreshwa nkigikoresho cyo kwikuramo munsi yikingira rya electronique.
Intandaro yo gutakaza dielectric: Niba ingano irwanya ibintu ari muke, bivuze ko izabyara amashanyarazi ava mumashanyarazi yumuriro w'amashanyarazi, bikavamo gukoresha ingufu muburyo bwubushyuhe, ibyo bita "gutakaza dielectric".
Kwiyerekana kw'ibimenyetso no kwambukiranya: Igihombo gikabije cya dielectric gitesha agaciro - ubwiza bwibimenyetso byerekana inshuro nyinshi, bigatera kwiyerekana, gutinda, ndetse no kunyura hagati yumurongo wibimenyetso byegeranye. Gusa ibikoresho bifite imbaraga nyinshi birwanya imbaraga birashobora kugumana imiterere ihamye ya dielectric, ikora nka insuliranteri 'iboneye' kugirango ibungabunge ibimenyetso byubuziranenge nubunyangamugayo.
3. "Indorerwamo yukuri" kubwiza bwibintu: Kugaragaza ubuziranenge nuburyo buhoraho
Kurwanya amajwi birumva cyane inenge ya micro imbere hamwe numwanda mubikoresho. Ikora nkumucamanza utajenjetse, igerageza ubuziranenge bwibikoresho.
Ikimenyetso cyanduye: niba ionic umwanda, ibice byibyuma cyangwa ibyuzuye byanduye bivanze mubikorwa byumusaruro, bizahita bigaragara muburwanya bwijwi, bivamo kugabanuka gukabije kwagaciro.
Inzira ihamye yo kwemeza: Turemeza neza imikorere ihamye mubice byose dukora ibizamini byo kurwanya ingano. Ihagarikwa rihamye kandi ryinshi ryerekana urunigi rwizewe hamwe nubushobozi budasanzwe bwo gukora.
3. Nigute ushobora guhitamo ibicuruzwa byiza kubucuruzi bwawe? Inama zo guhitamo abakoresha
Mu guhitamo nyirizina, turasaba ko abakiriya bakurikiza inzira ikurikira:
Kugaragaza urwego rwimikorere kubisabwa:
Strict level (high pressure, high frequency): high performance closed cell foam with volume resistivity>10 ^ 14 Ω · cm bigomba gutoranywa.
Standard level (consumer electronics, conventional sealing): volume resistivity>10 ^ 12 Ω · cm niwo shingiro.
Witondere ibidukikije: niba ibidukikije bikoreshwa ari ubuhehere, birakenewe guhitamo imiterere ya pore ifunze hamwe nigipimo gito cyo kwinjiza amazi, kuko iyinjizwa ryamazi rizatesha agaciro cyane ubukana bwijwi.
Sobanukirwa urupapuro rwamakuru hanyuma usabe raporo yikizamini:
Saba ibisobanuro birambuye kubicuruzwa byawe kandi wemeze ibipimo byabo byo kugerageza (urugero, ASTM D257).
Witondere imiterere yikizamini (ubushyuhe nubushuhe) kuko bishobora kugira ingaruka zikomeye kubisubizo.
Kora igenzura ry'umubiri:
Ku mishinga yingenzi, ibizamini byigenga byigenga bigomba gukorwa kuburugero rwibintu mbere yo gutanga amasoko kugirango bigenzurwe mubikorwa byakazi.
