Dow Corning (DOWSIL™) Ibifunga bya silikoni: Intangiriro n'ishyirwa mu bikorwa ry'ibipimo

Dow Corning, ubu ikorera munsi yaDOWSIL™ikirango nk'igice cya Dow Inc., niumushumba mukuru ku isi akaba n'umuyobozi mu ikoranabuhanga rya silicone. Yashinzwe mu 1943 nk'ubufatanye hagati ya The Dow Chemical Company na Corning Incorporated, iki kigo cyubatse umurage w'imyaka irenga 80 wo guhanga udushya, gitanga ibicuruzwa birenga 7,000 bishingiye kuri silicone n'ibisubizo ku bakiriya barenga 25,000 mu nganda zitandukanye. Izwi cyane kuberakuramba kudasanzwe, kwihanganira ikirere, no gukoresha uburyo butandukanye, Ibifunga bya silikoni bya DOWSIL™ byabaye urugero rwiza rwo gufunga, gufatanya, no kurinda mu bwubatsi, imodoka, ibikoresho by'ikoranabuhanga, inganda, n'ingufu zishobora kongera gukoreshwa. Bitandukanye n'ibifunga by'umwimerere, silikoni za DOWSIL™ zigumana ubworoherane, ituze, n'imikorere idasanzwe mu bushyuhe bukabije (-40°C kugeza 260°C), imirasire ya UV, n'ibidukikije bikomeye bya shimi, bitanga icyizere cy'igihe kirekire kiruta ibindi bisanzwe.

Ibyiza by'ingenzi ku bicuruzwa

Ibifunga bya silikoni bya DOWSIL™ biratandukanye bitewe n'uburyo bikoreshaimiterere yihariye y'ibikoreshobikemura ibibazo bikomeye by’inganda:

1. Ubudahangarwa bw'ikirere n'imiraba y'urumuri rwa UV ku rwego rwo hejuru: Bikozwe muri polimeri za silikoni zigezweho, birwanya gushwanyagurika, kwangirika no kwangirika igihe kirekire bitewe n'izuba ryinshi, ozone, n'imyanda ihumanya ikirere, bikomeza gukora neza mu gihe cy'imyaka irenga 20 mu bikorwa byo hanze.
2. Ubushyuhe bukabije buhamye: Gumana uburimbane no gufunga neza kuva ku bukonje bwa arctike kugeza ku nganda zishyushye cyane, biruta polyurethane na acrylic sealants mu gihe cy'ubushyuhe.
3. Gufata neza cyane: Bifatanya cyane n'ibirahure, icyuma, sima, amabuye, pulasitiki, ceramic, n'ubuso bwasizwe irangi—imiti myinshi itangagufatana nta primer, koroshya ishyirwaho no kugabanya ikiguzi cy'abakozi.
4. Ubudahangarwa bw'amazi n'ubutabire: Ikora uruzitiro rurerure kandi rudashobora kuvogerwa n'ubushuhe, imvura n'ubushuhe; irwanya amavuta, imiti isukura, isabune, na aside/alkali zoroshye, bigatuma biba byiza cyane mu nganda no mu mazi.
5. Ubushobozi bwo kugabanuka no kugenda buhoro buhoro: Kwakira ihindagurika ry'ingingo kuva kuri ± 25% kugeza kuri ± 50% nta gutsindwa, uhuze n'imiterere y'umubiri, kwaguka k'ubushyuhe, no guhindagura.
6. Birinda ibidukikije kandi bifite umutekano: Ibicuruzwa byinshi niifite VOC nkeya, ntabwo ihumanya, kandi nta mpumuro, byubahiriza amahame ya REACH, RoHS, n'inyubako zibungabunga ibidukikije, bibereye amazu yo mu nzu, ubuvuzi, n'ahantu hahurira abantu benshi.
7. Porogaramu yoroshye: Iboneka nk'uburyo bumwe bwo gukurura ibintu mu buryo bwa RTV (vulcanizing mu bushyuhe bw'icyumba)—nta mpamvu yo kuvanga, itangwa hakoreshejwe imbunda zisanzwe zo gufunga, ifite ubushobozi bwo kudapfukama ku ngingo zihagaze n'iziri hejuru.

Ingero z'Ishyirwa mu Bikorwa ry'Ingenzi

Ibifunga bya silikoni bya DOWSIL™ byakozwe mu rwego rwoahantu hatandukanye kandi hafite akamaro kanini, hamwe n'ibisubizo byihariye kuri buri nganda:

1. Ibahasha y'Ubwubatsi n'Inyubako

Igice kinini cy’ibikoresho bifunga DOWSIL™, gikoreshwa cyane, ni ingenzi mu bwubatsi bugezweho, bigamije ubuziranenge bw’inyubako n’ingufu zikoreshwa neza:

• Ikirahure cy'inyubako: DOWSIL™ 995 na 791 ni silicone zikomeye mu nganda zikoreshwa mu guhuza ibirahure, aluminiyumu, n'ibice bivanze n'inyubako, bigatuma imiterere y'inkuta z'amarido igaragara neza kandi igakomeza kwihanganira umuyaga.
• Gukingira ikirere: Ibifunga bya DOWSIL™ NP (neutral cure) na GP (acetic cure) bifunga amadirishya/inzugi, ingingo zo kwagura, aho igisenge cyinjira, n'icyuho cyo ku ruhande, birinda amazi kwinjira no gusohoka k'umwuka kugira ngo binoze ingufu zikoreshwa neza.
• Gusoza imbere: DOWSIL™ 780 ifunga ibikoresho byo mu bwiherero/mu gikoni, icyuma gifunga amatafari, n'aho amazi ahurira, irinda kwangirika kw'ibihumyo, ubwivumbure, n'amazi ahantu hari ubushuhe bwinshi.
• Ibikorwaremezo: Ikoreshwa mu biraro, mu mihanda yo munsi y'ubutaka, no mu mihanda minini kugira ngo ifunge aho inyubako zihurira, irinde sima kwangirika, kandi ihangane n'urujya n'uruza rw'abantu benshi n'ibibazo by'ibidukikije.

2. Imodoka n'Ubwikorezi

Ni iby'ingenzi ku mikorere y'imodoka, umutekano wayo, no kuramba kwayo:

• Moteri na Powertrain: Ibifunga bya DOWSIL™ 730 RTV bitanga gaskets zirinda ubushyuhe kuri moteri, transmissions, na sisitemu zo gusohora imyuka, zihangana n'amavuta, amavuta, n'ubushyuhe bugera kuri 260°C.
• Umubiri n'Ikirahure: Funga ibirahuri by'imbere, ibisenge by'izuba, n'amadirishya, bitanga ubushobozi bwo kudacika intege no kwirinda amazi mu gihe cy'impanuka.
• Imodoka zikoresha amashanyarazi (EV): DOWSIL™ 737 ifunga bateri, ibyuma bifite ingufu nyinshi, n'ibikoresho by'ikoranabuhanga (ECU), bikingira ubushuhe, umukungugu, n'ubushyuhe mu byuma bitanga ingufu za EV.

3. Ibikoresho by'ikoranabuhanga n'amashanyarazi

Ni ngombwa mu kurinda ibice by’ingenzi mu bikoresho by’ikoranabuhanga bikoreshwa n’abaguzi, inganda n’iby’indege:

• Uburinzi bwa PCB: Gupfuka ibikoresho bya Conformal (urugero, DOWSIL™ 1-2577) bifunga amabati yacapwe akingira ubushuhe, umukungugu, na ingese, bikerekana ko ibikoresho by'abakoresha, seriveri, n'ibikoresho byo kugenzura inganda bihamye.
• Amatara ya LED: Ibikoresho bipima refractive-index (urugero: CL-1000) birinda uduce twa LED, byongera urumuri n'ubushyuhe ku matara y'imodoka, amatara yo ku muhanda, n'amatara yo kwerekana.
• Ingufu n'itumanaho: Gufunga ibyuma bikingira amashanyarazi, transfoma, na sitasiyo z'ibanze za 5G, bitanga ubushyuhe n'ubukonje bukabije n'ibyanduza ibidukikije.

4. Inganda n'Inganda

Ku bikoresho bikomeye no kwizerwa mu mikorere:

• Gufunga Ibikoresho: DOWSIL™ 8888 ibifunga bishyushye cyane birinda amatanura, amatanura, n'imashini zo mu nganda, bihangana n'ubushyuhe n'ingufu.
• Guteranya no Guhuza: Ikoreshwa mu gukora ibikoresho (firigo, ifuru), sisitemu za HVAC, no gukora ibyuma, itanga uburyo bworoshye kandi burambye hagati y'ibikoresho bitandukanye.
• Inyanja n'Inyanja: Funga ibice by'ubwato, aho ubwato buhurira n'ibikoresho byo mu mazi, urinde amazi y'umunyu, imirasire ya UV, n'ikirere kibi cyo mu mazi kugira ngo birambe igihe kirekire.

5. Ingufu zisubira

Icy'ingenzi mu bikorwa remezo by'ingufu birambye:

• Sisitemu za PV zikoresha imirasire y'izuba: Funga amadirishya y'imashini zikoresha amashanyarazi, udusanduku duhuza ibyuma, n'inyubako zo gushyiraho, birinda ubushuhe n'ihindagurika ry'ubushyuhe kugira ngo byongere igihe cyo kubaho kw'imashini.
• Turbine z'umuyaga: Gufunga nacelles, ingingo z'ibyuma, na sisitemu zo kugenzura, bihangana n'umuyaga mwinshi, gutigita, no guhura n'umuyaga wo hanze mu mirima y'umuyaga yo ku nkombe no ku nkengero z'inyanja.

Umwanzuro

Ibifunga bya silikoni bya DOWSIL™ (byahoze ari Dow Corning) bigaragazaikoranabuhanga rya silicone ry'icyitegererezo, bihuza imyaka myinshi y’ubushakashatsi n’iterambere, ubumenyi mu bya siyansi, n’ubuhanga mu by’inganda. Kuva ku nkuta ndende kugeza kuri bateri za EV, kuva ku mashini z’inganda kugeza ku mirima y’izuba, ibi bifunga bitangaimikorere idasa na gato, kuramba, no kwizerwamu bikorwa bigoye cyane ku isi. Nk'umufatanyabikorwa wizewe w'abubatsi, injeniyeri, ba rwiyemezamirimo, n'inganda ku isi yose, DOWSIL™ ikomeje guhanga udushya, itanga ibisubizo birambye kandi bikora neza byo gufunga bigena ahazaza h'ubwubatsi, ubwikorezi, ikoranabuhanga, n'ingufu zishobora kongera gukoreshwa. Byaba ari ubwiherero bwo guturamo cyangwa umushinga munini w'ibikorwa remezo, DOWSIL™ sealants ni amahitamo yo kurinda no gutuza mu mutima igihe kirekire.
