Ifu ya silikoni ni imwe mu mavuta yo gufunga n’ibikoresho byo mu bwoko bwa kole mu buryo bugezweho. Ifite ubushobozi bwo koroshya ibintu, imara igihe kirekire, kandi irwanya ikirere n’ubushyuhe bukabije bituma iba amahitamo ya mbere ku banyamwuga ku isi yose.
Ariko, guhitamoubwoko bukwiye bwa silicone sealantNtabwo byoroshye nkuko bigaragara. Guhitamo nabi bishobora gutuma gufatana kw'imigozi kwangirika, kuvaho kw'amazi, kwangirika, cyangwa kongera kuyihindura bihenze. Iyi mfashanyigisho itanga uburyo bwo kuyikoresha neza.urwego rw'ubunyamwuga, hashingiwe ku bipimo mpuzamahanga (ASTM, ISO, GB), kugira ngo bigufashe guhitamo silicone sealant ikwiye umushinga wawe.
1. Huza agafunga n'agace k'ubutaka (Ibikoresho byo hejuru)
Ibifunga bya silikoni ntibihuye neza n'ibintu byose. Uburyo bubi bwo gukora bushobora gutera ingese cyangwa kwangirika kw'imigozi.
-Ikirahure n'Ikirahure
--Gukoreshasilicone ivura indwara idafata uruhu. Ibigize aside bishobora kwangiza ibyuma mu buryo bwo gukaranga.
--Urugero: Imishinga yo kubaka inkuta z'amarido nkaGare ya Beijing y'Amajyepfohakoreshejwe silicone idafite imiterere ifatika kugira ngo irambe imyaka irenga 20.
-Ipaneli za Aluminiyumu n'Ibyuma
-- Ibikoresho bya silikoni bivura imiterere y’ubutaka bigirwa inama yo kwirinda ogisijeni cyangwa ingese.
--ASTM C1184 isobanura ibisabwa mu mikorere y'ibikoresho bifunga ibyuma bikonjesha.
-Sima, Amabuye, n'Ububaji
--Ibyuma bifite imyobo bisaba primer mbere yo gukoresha silicone kugira ngo hirindwe ko bikururwa no kudafata neza.
--Silicone idakora neza ifite ubushobozi bwo kugenda cyane (± 50%) ni yo ikundwa cyane mu ngingo zo kwagura.
-Plasitiki (PVC, Polycarbonate, Acrylic)
--Si silicone zose zifata neza. Gupima niba zihuye ni ngombwa kuko zimwe muri plastiki zisohora amavuta abuza gukira.
--Mu byuma bikingira amashanyarazi, silicone za RTV (Ubushyuhe bw'icyumba) zirakunze kugaragara.
Inama y'inzobere:Buri gihe sabaUrupapuro rw'amakuru ya tekiniki (TDS)uvuye ku mutanga serivisi hanyuma urebe substrates zasabwe. Ku mishinga minini, kora ikizamini cyo guhuza ibintu mbere yo kubikoresha mu bwinshi.
2. Gukoresha imbere cyangwa hanze
Ibidukikije bitandukanye bisaba imiterere itandukanye cyane.
1. Gukoresha mu nzu
--Ibikoresho byo gufunga bya silikoni bifite isuku bifiteinyongeramusaruro zirwanya imiyoboroni byiza cyane mu gikoni, mu bwiherero, no mu miyoboro ya HVAC.
--Birinda ko ibihumyo by'umukara byiyongera ahantu hakonje kandi bigapimwa hakurikijwe ISO 846 kugira ngo harebwe niba birwanya mikorobe.
--Inyabutabire ntoya za VOC (imvange y’ibinyabuzima) zirasabwa kugira ngo zihuze n’ibipimo ngenderwaho by’ubwubatsi bw’icyatsi kibisi (LEED, BREEAM).
2. Porogaramu zo hanze
--Ibifunga bigomba kurwanyaImirasire ya UV, ozone, ihindagurika ry'ubushyuhe, n'imvura.
--Silicone ivura neza ifite ubushobozi bwo kurekura cyane (kugeza kuri 400%) ituma agapfunyika kaguma neza mu gihe cy'ubushyuhe bwinshi.
--Urugero:Icyicaro gikuru cya CCTV i Beijingikoreshwa cyane mu gufunga silicone ku ngingo zo ku ruhande rw'imbere zishobora kuba zifite ubukonje bwa -20°C n'ubushyuhe bwa +40°C.
3. Ibintu bitera stress ku bidukikije no ku mikorere ya mekanike
Mbere yo guhitamo icyuma gifunga, suzumaimimerere y'imihangayikoUmushinga wawe uzahura n'ibi bikurikira:
1). Ubudahangarwa bw'ubushyuhe
--Silicone zikoreshwa muri rusange: -40°C kugeza +150°C
--Silicone zishyuha cyane: kugeza kuri +300°C zihora zigaragara
Urugero: Gasket z'imodoka zikoresha silicone itukura ifite ubushyuhe bwinshi kugira ngo zirinde ubushyuhe bwa moteri.
2). Ubushuhe n'ubushuhe
--Ubwiherero n'ibikoni: koresha silicone y'isuku irimo imiti igabanya ububabare.
--Ibiraro byo hanze n'imiyoboro y'amazi: kurwanya kwibira mu mazi ni ingenzi cyane.
3). Ubushobozi bwo Kwimuka
--Bisobanurwa na ASTM C719 (guhindura uburyo bwo gufunga).
--Ingingo zo kwaguka mu gice cyo hejuru: ± 50% birakenewe ko umuntu agenda.
--Ibifunga bito bito (± 12.5%) bibereye gusa iyo hari icyuho gito.
4. Imiterere y'imiterere ugereranyije n'iy'ibitari imiterere
1). Ibifunga bya Silicone by'imiterere
--Ikoreshwa mu gutwikira amarido ku rukuta no mu gufatanya imizigo.
--Igomba kubahiriza ASTM C1184 cyangwa GB 16776 (Ubushinwa).
--Gusaba gutegura neza ubuso, igishushanyo mbonera cy'ingingo, no kugenzura ubuziranenge mu gihe cyo gushyiraho.
2). Ibikoresho rusange bya silikoni
--Ihendutse, yoroshye gushyiramo, kandi ikwiriye gusana urugo no gufunga ibintu bitari ngombwa.
--Igihe cy'ubuzima gisanzwe ni gito (imyaka 5-10) ugereranije na silicone z'imiterere (imyaka 20-30).
5. Impamyabushobozi n'Amahame y'Ubuziranenge
Abaguzi b'inzobere bagomba kugenzura ibyemezo by'ubuziranenge buri gihe:
--ISO 9001 na ISO 14001- Sisitemu zo gucunga ubuziranenge n'ibidukikije.
--Amahame ya ASTM– C920 (ibifunga ingingo bya elastomeric), C1184 (ibirahuri by'imiterere).
--Amahame ya GB (Ubushinwa)– GB/T 14683 (ibifunga by'inyubako).
--Ibimenyetso bya CE (Uburayi)- Yemeza ko iyubahirizwa ry’amahame y’umutekano n’ubudahangarwa bw’i Burayi.
Izi mpamyabumenyi zigabanya ibyago by’imishinga kandi zigatuma ibisabwa na leta n’inganda byubahirizwa.
6. Uburyo bworoshye bwo gushyira mu bikorwa
Silicone y'igice kimwe (RTV)
--Amakarito cyangwa sosiso byiteguye gukoreshwa.
--Ivura ikoresheje ubushuhe buri mu kirere, akenshi mu masaha 24–48.
--Byiza cyane ku mbuga aho umuvuduko n'uburyo bworoshye ari ngombwa.
Silicone ifite ibice bibiri
--Bisaba kuvanga, ariko bikira vuba cyane kandi mu buryo buhoraho.
--Byakunzwe cyaneibirahuri byo mu rugandanaimirongo y'inganda iteranyirizwamo.
Urugero: Ikoreshwa mu miyoboro y'ingufu zikora ku nkuta kugira ngo ikomeze gushonga neza.
7. Ikiguzi ugereranije n'imikorere y'ubuzima
Birashishikaje guhitamo sealant ihendutse, ariko ikiguzi cy'ubuzima bwose ni cyo cy'ingenzi kurushaho.
--Igifunga gihendutse: gupfukirana kugabanuka, ibara rihinduka, gucikagurika mu myaka 3-5.
--Silicone y'imiterere y'imbere: Imyaka 20–30 yo gukora, ikiguzi gito cyo kubungabunga, hamwe n'inyungu nziza y'igihe kirekire.
--Mu mishinga minini y'ubwubatsi,Ikiguzi cyo gufunga ni <1% by'ingengo y'imari yose yo ku ruhandeariko gucika kw'imashini ifunga ibintu bishobora gutuma abantu benshi basanwa.
