Dow Corning, ikozvino iri kushanda pasi peDOWSIL™kambani sechikamu cheDow Inc., ikambanipiyona wepasi rose uye mutungamiri mune tekinoroji yesiliconeYakavambwa muna 1943 semubatanidzwa pakati peThe Dow Chemical Company neCorning Incorporated, kambani iyi yakavaka nhaka yemakore anopfuura makumi masere ekugadzira zvinhu zvitsva, ichipa zvigadzirwa nemhinduro zvinodarika 7,000 zvakagadzirwa nesilicone kune vatengi vanopfuura 25,000 mumaindasitiri akasiyana.kugara kwenguva refu kusingaenzaniswi, kuramba mamiriro ekunze, uye kushanduka-shanduka kwezvinhuDOWSIL™ silicone sealants yave ndiyo nzira yakanakisisa yekuvhara, kusunga, uye kudzivirira mukuvaka, mota, zvemagetsi, zvemaindasitiri, uye zvikamu zvesimba rinogona kudzokororwa. Kusiyana neorganic sealants, DOWSIL™ silicones dzinochengetedza kuchinjika, kugadzikana, uye kushanda zvakanaka mumamiriro ekunze ekupisa kwakanyanya (-40°C kusvika 260°C), kuratidzwa kweUV, uye nharaunda dzakaoma dzemakemikari, zvichipa kuvimbika kwenguva refu kunopfuura dzimwe nzira dzechinyakare.

Zvakanakira Zvigadzirwa Zvikuru

DOWSIL™ silicone sealants inoonekwa zvakanyanya nekuda kwehunhu hwezvinhu zvakasiyanazvinogadzirisa matambudziko makuru eindasitiri:

1. Kudzivirira Mamiriro Ekunze Akanaka Uye UV: Yakagadzirwa nemapolymers epamusoro esilicone, inodzivirira kutsvuka, kutsemuka, uye kuora pasi pezuva kwenguva refu, ozone, uye kusvibiswa kwemhepo, ichichengetedza kushanda kwemakore anopfuura makumi maviri mukushandiswa kwekunze.
2. Kugadzikana Kwekupisa Kwakanyanya: Chengetedza kusimba uye kusimba kwekuchengetedza kubva mumamiriro ekunze anotonhora eArctic kusvika kunzvimbo dzemaindasitiri dzinopisa zvakanyanya, uchikunda polyurethane uye acrylic sealants mukupisa kwemhepo.
3. Kunamira Kwakanaka: Inobatana zvakasimba negirazi, simbi, kongiri, matombo, purasitiki, ceramic, uye nzvimbo dzakapendwa—maumbirwo akawanda anopakunamira kusina primer, zvichiita kuti kuisa zvive nyore uye kuderedza mari yevashandi.
4. Kuramba Kusapinda Mvura & Kurapwa Nemakemikari: Gadzira chipingamupinyi chakakora, chisingapindi mvura kubva muhunyoro, mvura, uye hunyoro; dzivirira mafuta, zvinonyungudutsa, sipo, uye maasidhi/alkali akapfava, zvichiita kuti zvive zvakanaka munzvimbo dzakaoma dzemaindasitiri nedzemugungwa.
5. Kuderera Kwakaderera & Kukwanisa Kufamba Kwakakwirira: Gadzirira kufamba kwemajoini kwe±25% kusvika ±50% pasina kukundikana, uchichinja kuti zvienderane nekugadzikana kwechimiro, kuwedzera kwekupisa, uye kudedera.
6. Inoshamwaridzana Nezvakatipoteredza uye Yakachengeteka: Zvigadzirwa zvakawandaine VOC shoma, haina chepfu, uye haina hwema, zvichitevedzera REACH, RoHS, uye mitemo yekuvaka yakasvibirira, yakakodzera dzimba dzemukati, hutano, uye nzvimbo dzeveruzhinji.
7. Kushandisa Kuri Nyore: Inowanikwa senzira imwe chete yeRTV (kuputira jira nekupisa kwekamuri)—hapana kusanganiswa kunodiwa, kunopihwa nepfuti dze caulking dzakajairwa, dzine hunhu husingatsvedzeri hwemajoini akamira nepamusoro.

Maitiro Ekushandisa Kiyi

DOWSIL™ silicone sealants yakagadzirwa kuti ishandenzvimbo dzakasiyana-siyana, dzine njodzi huru, nemhinduro dzakagadzirirwa indasitiri yega yega:

1. Envelopu yekuvaka nekuvaka

Chikamu chikuru chekushandisa, DOWSIL™ sealants chakakosha mukuvaka kwemazuva ano, zvichivimbisa kusimba kwechimiro uye kushanda zvakanaka kwesimba:

• Kupenya KwemagadzirirwoDOWSIL™ 995 na791 imhando dzesilicone dzinotungamira muindasitiri dzekubatanidza magirazi, aruminiyamu, uye mapaneru ekubatanidza kumafuremu ekuvaka, zvichiita kuti magadzirirwo emadziro emaketeni ave nemaonero asina kuvharwa uye kudzivirira kurema kwemhepo.
• Kudzivirira mamiriro ekunze: DOWSIL™ NP (neutral cure) uye GP (acetic cure) sealants zvinovhara mahwindo/masuo, majoini ekuwedzera, kupinda kwedenga, uye maburi epamberi, zvichidzivirira kupinda kwemvura uye kubuda kwemhepo kuti zvivandudze mashandiro esimba.
• Kupedzisa Kwemukati: DOWSIL™ 780 inovhara zvinhu zvekugezera/kicheni, tile grout, uye majoini evanity, ichidzivirira chakuvhuvhu, ganda, uye kukuvara kwemvura munzvimbo dzine hunyoro hwakawanda.
• Zvivakwa: Inoshandiswa mumabhiriji, mumatuneri, uye mumigwagwa mikuru kuvhara majoini ekuwedzera, kudzivirira kongiri kubva mukuora, uye kutsungirira kufamba kwakawanda kwemotokari uye kushushikana kwezvakatipoteredza.

2. Mota & Kutakurwa

Zvakakosha pakushanda zvakanaka kwemotokari, kuchengetedzeka kwayo, uye kugara kwenguva refu:

• Injini & Powertrain: DOWSIL™ 730 RTV sealants inogadzira magasket asingapisi einjini, magetsi, uye masisitimu eutsi, anodzivirira mafuta, mafuta, uye tembiricha inosvika 260°C.
• Muviri neGirazi: Vhara magirazi epamberi, matenga ezuva, uye mahwindo, zvichiita kuti pasave nekudzungunyika uye kudzivirira mvura ukuwo zvichichengetedza chimiro chazvo kana kukuvara kwaitika.
• Mota dzemagetsi (maEV): DOWSIL™ 737 inovhara mabheteri, materminal ane voltage yakawanda, uye mayuniti ekudzora emagetsi (ECUs), zvichidzivirira kubva pakunyorova, guruva, uye kushushikana kwekupisa mumagetsi emagetsi eEV.

3. Zvigadzirwa zvemagetsi nemagetsi

Zvakakosha pakudzivirira zvinhu zvinonzwa zviri nyore mumagetsi emagetsi evatengi, maindasitiri, uye emuchadenga:

• Dziviriro yePCB: Mapendi eConformal (semuenzaniso, DOWSIL™ 1-2577) anovhara mabhodhi ecircuit akadhindwa kuti asanyoroveswe, guruva, uye ngura, zvichiita kuti zvishandiso zvevatengi, maseva, uye maindasitiri zvivimbike.
• Mwenje we LED: Zvivharo zvine refractive index (semuenzaniso, CL-1000) zvinodzivirira ma LED chips, zvichiwedzera kugadzika kwechiedza uye kugadzikana kwekupisa kwemwenje yemotokari, mwenje yemumugwagwa, uye mapaneru ekuratidza.
• Simba & Nhare: Vhara mavharo emagetsi, matransformer, uye nzvimbo dzemagetsi dze5G, zvichipa kudzivirira kupisa kwakanyanya uye kusimba kubva kumhepo inopisa uye kusvibiswa kwezvakatipoteredza.

4. Maindasitiri & Kugadzira

Kune michina inorema uye kuvimbika kwemaitiro:

• Kuisa Chisimbiso cheMidziyo: DOWSIL™ 8888 zvinovhara kupisa kwakanyanya zvinodzivirira maovheni, maovheni, nemichina yemumaindasitiri, zvichitsungirira kupisa uye kusvibiswa nemakemikari.
• Kuungana & Kubatana: Inoshandiswa mukugadzira midziyo yemagetsi (mafiriji, maovheni), masisitimu eHVAC, uye kugadzira simbi, ichipa hukama hwakasimba uye hunochinjika pakati pezvinhu zvakasiyana.
• Zvemugungwa nepamhenderekedzo yegungwa: Vhara zvidimbu zvegungwa, majoini edhiki, uye zvishandiso zvemugungwa, uchidzivirira mvura yemunyu, mwaranzi yeUV, uye mamiriro ekunze akaoma emugungwa kuti zvigare kwenguva refu.

5. Simba Rinodzokororwa

Zvakakosha pakuvaka zvivakwa zvemagetsi zvinogara kwenguva refu:

• Masisitimu ezuva ePV: Vhara mafuremu epaneru emagetsi, mabhokisi ekubatanidza, uye zvivakwa zvekuisa, zvichidzivirira kubva pakunyorova nekushanduka-shanduka kwetembiricha kuti pave nehupenyu hwepaneru.
• Maturbine emhepo: Vhara ma nacelles, majoini emapanga, uye masisitimu ekudzora, zvichidzivirira mhepo ine simba, kudedera, uye kubuda kunze mumapurazi emhepo ari pamhenderekedzo yegungwa nepamhenderekedzo yegungwa.

Mhedziso

DOWSIL™ (yaimbova Dow Corning) silicone sealants inomiririrahukuru hwetekinoroji yesilicone, kusanganisa makumi emakore eR&D, hunyanzvi hwesainzi yezvinhu, uye mainjiniya akanangana neindasitiri. Kubva pamadziro marefu kusvika kumabhatiri eEV, kubva kumichina yemaindasitiri kusvika kumapurazi ezuva, ma sealant aya anounzakushanda kusingaenzaniswi, kugara kwenguva refu, uye kuvimbikamuzvishandiso zvinonyanya kudiwa pasi rose. Semubatsiri anovimbwa nevagadziri vezvivakwa, mainjiniya, makondirakiti, nevagadziri pasi rose, DOWSIL™ inoramba ichishanda nesimba idzva, ichipa mhinduro dzinogara kwenguva refu, dzinoshanda zvakanaka dzinoumba ramangwana rekuvaka, kutakurwa, zvemagetsi, uye simba rinodzokororwa. Ingave yeimba yekugezera yekugara kana chirongwa chikuru chezvivakwa, DOWSIL™ sealants ndiyo sarudzo yekudzivirira kwenguva refu uye rugare rwepfungwa.
