PTFE Tape Munyu Spray Resistance & Marine Application Zvinodiwa

PTFE high-temperature tepi inoshandiswa zvakanyanya munzvimbo dzemugungwa - pamapuratifomu ekumahombekombe, ngarava, maturbine emhepo emahombekombe, uye nzvimbo dzemaindasitiri dzine munyu. Iyo PTFE yekupfekedza pachayo inoshingirira kupfapfaidza munyu. Nekudaro, kuita kwetepi kwese kunoenderana nemapoinzi maviri asina simba: iyo inonamira layer uye mipendero yefiberglass substrate..

Kupfapfaidza munyu kunogona kupinda kuburikidza neanonamira nzvimbo kana tambo mukati mefiberglass mipendero, zvichikonzera kurasikirwa kwekunamira kana substrate corrosion. Naizvozvo, kuongorora munyu kupfapfaidza kuramba kunoreva kuyedza kana iyo inonamira ichichengeta simba rekubatanidza, inopikisa kunyudzwa kwemvura, uye inodzivirira simbi iri pasi.

Aokai PTFE inogadzira tepi yePTFE yakatenderwa basa remugungwa. Gwaro iri rinotsanangura nzira dzekuyedza dzakajairwa, maitiro ekugamuchirwa, uye zvinodiwa zvekushandisa kune yakakwirira-munyu-mhute nharaunda.

Salt Spray Test Methods yePTFE Tape

Kuyedzwa kwakamisikidzwa kunovimbisa kuti tepi inosangana nekusimba kwemarine-giredhi. Nzira yakajairika ndeyekusarerekera munyu spray (NSS) pa ISO 9227 kana ASTM B117.

1. Kugadzirira kwemuenzaniso

1. Laminate tepi yePTFE pane yakajairwa simbi yekuyedza pani (semuenzaniso, SUS304 Stainless simbi kana iyo yakanangwa substrate) uchishandisa roller.

2. Nama mipendero yematepi nechisimbiso chisingapindi mvura kudzivirira kupinda kwemhute yemunyu isina kujairika kubva kumacheto akachekwa. Izvi zvinotevedzera kuisirwa kwakakodzera uko mipendero inodzivirirwa.

3. Gadzirira mienzaniso yakakwana yepre-test, post-test, uye control mapoka.

2. Kufumura mhute yemunyu

• Isa zvienzaniso muimba yekupfapfaidza munyu pa35°C, 5% NaCl solution.

• Nguva yekuyedza: 96h, 240h, 500h, 1000h , kana sekubvumirana.

• Tilt test panels pa15°–30° kubva pakatwasuka kuti nyangwe mhute yemunyu inoiswa.

3. Ongororo mushure mekuratidzwa (suka uye woomesa)

Zvinodiwa Zvekushandisa ZveMarine & Yakakwira-Munyu-Fog Nzvimbo

Kushandiswa kwepasirese kumapuratifomu ekumahombekombe, ngarava, nzvimbo dzemagetsi emhepo dzemahombekombe, uye nzvimbo dzeindasitiri dzine mhute yemunyu wakanyanya, PTFE tepi inofanirwa kusangana nemaitiro akaomarara.

1. Adhesive - silicone PSA inosungirwa

• Silicone pressure-sensitive adhesive: Ultra-low mwando kunyura, yakasarudzika munyu fog kuramba, mamiriro ekunze. Inochengetedza simba rekubatanidza kwenguva refu uye haiparadze simbi isina tsvina.

• Acrylic PSA - HAISI yakakodzera: Inyore hydrolyzes, plasticizes, uye inorasikirwa nekunamira pasi pekushisa kwakanyanya uye inorema munyu mhute. Acrylic haifanirwe kushandiswa munzvimbo dzemugungwa.

2. Substrate uye kumucheto kudzivirira

• Iro jira refiberglass rinofanirwa kunge rakaiswa zvizere nePTFE , isina mapinho. Izvi zvinodzivirira munyu kupinda kuburikidza necapillary chiito pamwe chete nefibers, izvo zvingakonzera delamination.

• Panguva yekuisa, chisimbiso tepi inoputira uye mipendero ine yakatsaurirwa mamiriro ekunze-resistant sealant (semuenzaniso, silicone-based). Izvi zvinovharira nzira dzekupinda nemhute munyu - danho rakakosha kwazvo rekuvimbika kwenguva refu.

3. Yakakurudzirwa munyu pfapfaidzo kuramba indices

• Minimum 1000h neutral salt spray (NSS) pasina kusimudza zvega kana kuputika.

• 180 ° svuura simba rekuchengetedza ≥80% mushure me1000h.

• Hapana ngura pane iri pasi pesimbi (kana ngura inotsvaga mukati memiganhu yakabvumiranwa).

• Pamamiriro ezvinhu akaoma zvikuru (semuenzaniso, nzvimbo dzemugungwa dzemuchadenga dzine kunyorova-kuoma), 2000h NSS kana cyclic corrosion test (CCT) inokurudzirwa.

4. Kuchinjika kune zvakasanganiswa nharaunda

• Tembiricha yakakwira + mhute yemunyu: Kuputira pombi yekupedza kana kupisa-kuteya tambo yekuvharisa, ita bvunzo dzakasanganiswa dzekuchembera (kupisa kukuru + munyu pfapfaidzo).

• Kuratidzwa kweUV: Kushandiswa kwekunze kwemugungwa kunoda kupikisa kweUV - chinonamira hachifanire kuvharika kana kubatanidza pasi pemwaranzi yeultraviolet.

5. Kuiswa uye kugadzirisa

• Kugadzirira kwepamusoro: Degrease zvizere uye derust bonding nzvimbo. Kufananidza primer inokurudzirwa kuti iwedzere kubatana kwemukati uye kuvhara munyu fog intrusion.

• Kugara uchiongorora: Tarisa matepi micheto panguva yebasa rekuputika kana kusvuura. Tsiva tape yakakundikana nekukasira kudzivirira crevice corrosion yeyakasungwa chimiro.

Pfupiso - Zvinhu Zvinokosha zveMarine-Giredhi PTFE Tepi

Aokai PTFE inopa PTFE yakakwirira-tembiricha tepi yakatenderwa kugungwa uye yakakwirira-munyu-mhute nharaunda. Yedu silicone PSA kuumbwa kwapfuura 1000h NSS kuyedzwa ne> 85% peel simba rekuchengetedza. Isu tinopawo primer uye edge sealant kurudziro. Bata isu kune mishumo yebvunzo uye nhungamiro yekushandisa.

Zviri pamusoro apa zvinopihwa ne Jiangsu Aokai New Materials Technology Co., Ltd.

Kana iwe uchida kudzidza zvakawanda pamusoro pezvakatsanangurwa zvakatsanangurwa, mamiriro ekushandisa uye zvigadziriso zvakagadziridzwa zvechigadzirwa chedu chizere, kusanganisira PTFE machira ekupisa, PTFE yakakwirira-tembiricha matepi, PTFE mesh mabhandi, seamless bonding muchina mabhandi, single-sided PTFE jira, yakakwirira-tembiricha inodzivirira inodzivirira machira egirazi, uye machira anodzivirira girazi
