Muzvikamu zvakaita semagetsi evatengi, kugadzira mota, midziyo yekunze, uye michina yekurapa, zviyero zvekudzivirira zvigadzirwa zvave zvakakosha bhenji. Pakati peizvi, IP67-chiyero chedziviriro chakagamuchirwa nevakawanda-chinoda kuti zvigadzirwa zvikwanise kusamira guruva uye kudzivirira kunyudzwa mumvura kwenguva pfupi. Kusangana nechiyero ichi kunoenderana nepamusoro-kuita chisimbiso zvinhu. Silicone foam, ine yakasarudzika physicochemical zvimiro, inomira pachena sesarudzo yakanaka yekuwana IP67 kuchengetedzwa.
一, Ongororo yeIP67 Dziviriro Level
Iyo IP (Ingress Dziviriro) chiyero, yakagadzwa neInternational Electrotechnical Commission (IEC 60529), inotsanangura kugona kwekudzivirira kwemidziyo yemagetsi yakavharirwa kubva kune yakasimba yekunze zvinhu uye mvura ingress.
Nhamba yekutanga "6": inomiririra yepamusoro-soro yekudzivirira guruva, kudzivirira zvachose guruva kupinda.
Nhamba yechipiri "7": inoratidza kuti inogona kunyudzwa mumvura kwenguva pfupi kusvika 1 mita yakadzika (kazhinji maminitsi makumi matatu) pasina kukanganiswa.
Kuti uwane IP67 chiyero, matambudziko maviri akakosha anofanirwa kugadziriswa: kuwana chisimbiso chakakwana chemicroscopic pores uye kudzoreredza chimiro chayo chepakutanga pasi pekumanikidzwa kwemvura.
2, Scientific Properties yeSilicone Foam Zvinhu
1. Microstructural zvakanakira
Silicone furo zvinhu inoumbwa kuburikidza nemakemikari kana emuviri foam process, ine silicone rabha sematrix uye ine yakafanana yakavharwa pores.
Mwero wepore yakavharwa inogona kusvika kupfuura 95%: iyo yakazvimirira yakavharwa pore chimiro inovhara nzira yemvura uye gasi kupinda.
Controllable aperture: Kugadziriswa kwemaitiro kunogonesa aperture renji ye50-500μm kuti isangane nemhando dzakasiyana dzekuisa chisimbiso.
Zvitatu-dimensional network structure:Siloxane musana uye organic side mapoka anoumba elastic network kupa kugadzikana kwemaitiro.
2. Makiyi emidziyo yemuviri paramita
| Performance Index | Typical Range | Mupiro kune IP67 Performance |
| Compression deformation rate | 5-20% (70 dhigirii ×22h) | -nguva refu yekubata pressure Compression deformation rate |
| Rebound rate | Yakakura kupfuura kana kuenzana ne90% | nokuda kwokuparurazve nokuungana |
| Density | 0.3-0.8g/cm*3 | Kuenzana pakati pekureruka nekuisa chisimbiso |
| Chiyero chekuvhara pore | Yakakura kupfuura kana kuenzana ne95% | vhara chiteshi chemvura chinopinda |
| Kudzvinyirira simba deformation | 0.02-0.2MPa (25% compression) | inopa chisimbiso chinopfuurira |
3. Kuchinja kwezvakatipoteredza
Kushivirira kwetembiricha: inochengetedza elasticity kubva-60 dhigirii kusvika 200 dhigirii (zvakajairwa furo zvinhu zvinowanzoita brittle pakudziya kwakaderera)
Chemical inertness: inoshingirira kuozone, ultraviolet, weak acids uye alkalis isina simba, uye kudzivirira kusashanda zvakanaka kunokonzerwa ne-kukwegura kwenguva refu.
Dikinuro diki isingaperi: inogona kudzoreredza kuchimiro chepakutanga pasi pe-kudzvanywa kwenguva refu, kudzivirira kutadza kuvharika nekuda kwekuzorodza pfungwa.
3, Injiniya Mechanism Yekuziva IP67 Kuisa Chisimbiso
1. Interface yekuisa chisimbiso meshini Kana iyo silicone foam zvinhu yakatsikirirwa uye kuiswa pakati peimba nendiro yekuvharira:
Kuisa chisimbiso: 1. Kudzvanya kwekutanga (kazhinji 25-40%) → Kuchinja kwechimiro chebubble 2. Kuwedzera kudhumhana pakati pemadziro ebhubhu → Kugadzirwa kwechisimbiso chinoramba chiripo.
Iyo yekudzvinyirirwa kwemvura modhi pasi pe1 m kudzika kwemvura (inenge 9.8kPa hydrostatic pressure): simba rekudzoreredza remuviri elastic rakakura kupfuura simba remvura rinopinda. Pamusoro pesimba rekuita: simba repamusoro resilica gel (inenge 24 mN/m) rakaderera pane tension yepasi pemvura (72 mN/m), ichigadzira hydrophobic barriers. Iyo pore pressure balance: iyo gasi pressure mupore yakavharwa inogona kudzikamisa zvishoma kumanikidza kwemvura yekunze.

4. Mapoinzi Akakosha Mukugadzirwa Kwekushandisa
1. Chimiro chekugadzira kuenzanisa
Kuverengera kwereshiyo yekudzvanya: iyo optimal compression reshiyo inofanirwa kutariswa zvinoenderana nekudzvanyirira kushushikana-kumisikidza curve yechinhu.
Groove dhizaini: Iyo yakakurudzirwa hupamhi ndeye 10-15% yakakura kupfuura iyo dhayamita yemidziyo, uye kudzika kuri 20-30% idiki (kuumba zvine mwero compression).
Corner treatment: Shandisai kuramba muchiwedzera kana kufa-kucheka kudzivirira kupatsanura maburi.
2. Chimiro chekusarudza zvinhu
Mamiriro ekushandisa Density kusarudzwa Kuomarara siyana Zvinodiwa zvakakosha
Consumer electronics 0.4-0.6g/cm*{1}} Shore C Low volatile matter (anti-fog)
Zvemagetsi zvemotokari 0.5-0.7g/cm*3 20-40 Shore C Mafuta uye inoshingirira kupisa
Mwenje wekunze 0.6-0.8g/cm*3 30-50 Shore C Yakanatsiridza UV kuramba
3. Matanho ekudzivirira pakukundikana
Kudzvanya Permanent Deformation Test: Kusimbisa Kwenguva Yakareba-Kuita Chisimbiso Chinoenderana neASTM D395
Thermal kuchembera simulation: 1000 maawa kuita shanduko pasi pe85℃/ 85% RH
Kutonhora uye kupisa kuvhunduka bvunzo: interface adhesion bvunzo pa-40 dhigirii kusvika 85 dhigirii
5, Kuedza uye Verification Nzira
Kuve nechokwadi chekuti silicone foam zvinhu zvinosangana neIP67 zvinodiwa mumashandisirwo anoshanda, inotevera nzira yekuongorora inokurudzirwa:
Material-level tests: Porosity analysis (SEM yekutarisa yakavharwa-cell rate) / compressive stress relaxation test (ASTM D395 Method B) / water vapor transmission test (ASTM E96)
Component-level tests: Compression force decay test (kufananidza makore mashanu ekushandiswa)/interface wetting angle test (verifying hydrophobicity)/compression rebound test mushure mekutenderera tembiricha.
Sisitimu-yekuyedza nhanho: Kuora kwechidhindo bvunzo (sensitivity kusvika 0.01Pa), IP67 yakajairwa kunyudzwa mumvura (1-mita kunyudzwa kwemaminetsi makumi matatu), uye guruva mukamuri bvunzo (8-awa ichienderera mberi guruva kuratidzwa).
