Semugadziri wenyanzvi we PTFE adhesive tepi uye zvine hukama zvigadzirwa zvekudzivirira, Jiangsu Aokai New Materials Technology Co., Ltd. inogovera ruzivo rwakakosha. Kunyange zvazvo PTFE yakakwirira-temperature tepi ichikosheswa nokuda kwayo yakanakisa dielectric zvivakwa uye kugadzikana kwekupisa, hutsinye hwepamusoro-frequency uye high-voltage yekushanda mamiriro anosuma akawanda angangoita njodzi.
Kunzwisisa njodzi idzi - dzinosanganisira kuchembera kwepamusoro-tembiricha, kuparara kwemagetsi, kurasikirwa kwepamusoro-frequency, uye mamiriro ezvakatipoteredza - kwakakosha kune yakavimbika system dhizaini.
Njodzi dzeKusimba Kwemagetsi
Yakakwira-Voltage Kuputsa: PTFE matepi ane mashoma dielectric breakdown kuramba. Semuenzaniso, tepi ine 0.11mm yakazara ukobvu inogona kunge iine voltage yekuputsika inosvika 6.1kV. Ukobvu husina kukwana kana kusvibiswa kwemukati (pinholes, zvinosvibisa) zvinogona kukonzera kuparara kwepamusoro-voltage uye kutadza kwekudzivirira.
Kubuda Kwakasarudzika (Kubuda kweCorona): Munzvimbo dzakakwirira-voltage, zvinosvibisa pamusoro (guruva, mavara emafuta) uye madiki madiki emhepo emukati anogadzira nzvimbo dzemagetsi dzemagetsi, zvichikonzera kubuda kwecorona. Kubuda kwenguva refu kunoramba kuchiita zvishoma nezvishoma kunokanganisa insulating layer, zvichiita kuti kukundikana kusati kwasvika.
Insulation Deterioration kubva kune Environmental Factors:
Humidity: Kana hunyoro hwehukama hunopfuura 85%, iyo PTFE resistivity inogona kudonha zvakanyanya - kubva 10⊃1;⁷Ω kusvika kutenderera 10⊃1;⊃2;Ω - uye breakdown voltage inogona kuderera ne30% kusvika 50%.
Zvinosvibisa: Hupfu inoitisa kana munyu pfapfaidzo pamatepi pamusoro inoumba mabhiriji anofambisa, achigadzira kuvuza nzira dzazvino.
Mumagetsi emagetsi epamusoro-soro, simba re dielectric rematepi ePTFE haisi kukosha kwakagadziriswa asi kunoenderana zvakanyanya nemamiriro ekushandiswa. Kune corona-resistant mamakisi, vagadziri vanowanzo batanidza inorganic fillers senge mica kana ceramic zvimedu muPTFE matrix. Aya mafirita anogadzira akawanda ma-micro-interface anoparadzira kusungirirwa kwechaji uye anodzvinyirira chikamu chekuburitsa. Pakusarudza tepi yePTFE yemagetsi emagetsi emagetsi emagetsi akakwira (semuenzaniso, 6kV kusvika 10kV kirasi), zvinokurudzirwa kushandisa corona-resistant PTFE tepi ine ukobvu hunosvika 0.18mm uye simbisa iyo partial discharge inception voltage (PDIV) pasi petembiricha chaiyo yekushandisa, sezvo PDIV inowanzodzikira ne530% mukamuri kana ichienzaniswa ne530%.
Thermal Kugadzikana Ngozi
High-Temperature Kuchembera: PTFE matepi anogona kazhinji kushanda zvakatsiga pakuenderera tembiricha ye260°C. Zvisinei, kana tembiricha yadarika 250°C (kunyanya pedyo ne300°C), cheni dzemamorekuru dzinotanga kuora. Kuora uku kunoderedza zvakanyanya simba re dielectric uye kunogadzira njodzi yekutadza kuvhara.
Thermal-Oxygen Synergistic Effect: Iko kusanganiswa kwekushisa kwepamusoro uye oksijeni inokurumidzira kukwegura kwezvinhu. Pasi pemamiriro ekupisa uye munyoro, kukuvadzwa kwekuita kwevoltage kuramba kunogona kuwedzera ne30% kusvika 50% zvichienzaniswa nekupisa kwakaoma chete.
Kana PTFE tepi ichishandiswa mune yakavharirwa switchgear kana transformer windings apo okisijeni inogumira, hunhu hwekuchembera hunopisa hunosiyana zvakanyanya kubva kune yakavhurika-mhepo mamiriro. Zvidzidzo zvinoratidza kuti PTFE's thermal decomposition rate munitrogen inosvika chikamu chimwe kubva mugumi cheiyo mumhepo patembiricha imwe chete. Izvi zvinoreva kuti kune hermetically yakavharwa yakakwirira-voltage zvikamu, PTFE tepi inogona kuwana hupenyu hwesevhisi hurefu kunyangwe patembiricha zvishoma pamusoro pe260°C. Nekudaro, kana kuora kwatanga, ne-zvakagadzirwa zvakaita secarbonyl fluoride uye perfluoroisobutylene zvine muchetura uye zvinoparadza kune zvinobatika nesimbi. Naizvozvo, zvakakosha kuti uve nechokwadi chekuti tembiricha yekushandisa inoramba iri pazasi pechikumbaridzo chekuora - muganho wekuchengetedza we30-50 ° C unokurudzirwa kune yakakosha-yakanyanya-voltage insulation.
High-Frequency Characteristic Risks
Signal Attenuation uye Distortion: Iyo dielectric inogara (Dk) yeyakajairwa PTFE inotangira kubva 2.0 kusvika 2.6. Zvigadzirwa zvine kutsauka kwakanyanya muDk zvinogona kukonzera kudzikisira uye kukanganisa kweakakwira-frequency masaini panguva yekufambisa - nyaya yakakosha yeRF uye microwave application.
Heat Generation Effect: PTFE ine yakanyanya kuderera dielectric kurasikirwa tangent (tan δ), kazhinji pazasi 0.0025. Zvisinei, kana kurasikirwa kwakanyanya kwakanyanya (nekuda kwekusvibiswa kana kushandiswa kusina kunaka), kupisa kwakanyanya kunogadzirwa pasi pemagetsi emagetsi. Izvi zvekuzvipisa zvinomhanyisa kuchembera kwezvinhu uye zvinogona kutungamira mukutiza kwekupisa.
Mechanical & Environmental Adaptability Ngozi
Mechanical Stress Kukuvara: Kugara kunetsana uye kupokana panguva yekuisa kana kushanda kunogona kukonzera micro-kutsemuka uye abrasion mukati mechinhu, ichikuvadza iyo yakazara insulation kuita. Mabhende akapinza kana mipendero inofanira kudzivirirwa.
Kemikari & Radiation Corrosion: Midhiya yakasimba inoparadza senge yakanyungudutswa alkali simbi uye chlorinated hydrocarbons, pamwe nekuwandisa-ane simba remwaranzi (kupfuura 10⁴ Gy), ichaparadza mamolecular chimiro chePTFE uye nekudzikisa zvakanyanya simba rayo re dielectric.
Adhesive Kutadza: Kusarudzika kwekunamira kusarudzwa (semuenzaniso, acrylic-based adhesives) inogona kupfava uye kurasikirwa nekunamira pasi pekushisa kwepamusoro, zvichikonzera kutama kwe tepi, kusunungura, kana kukambaira - kunyanya kunetsa mune vertical kana vibrating application.
Low-Temperature Brittleness: Mazhinji matepi ePTFE anorasikirwa nekuchinjika uye anoita brittle kana tembiricha yadzikira pasi -70°C. Kunyange zvisingawanzo mukushandisa magetsi, izvi zvine basa kune zvekunze kana zvemuchadenga zvakafumurwa kutonhora kwakanyanya.
Mhedziso - Njodzi-Kuziva Sarudzo Inovimbisa Kuvimbika
Kushandisa PTFE adhesive tepi mu-high-voltage uye high-frequency applications inoda kunyatsotariswa kwezvipingamupinyi zvakawanda. Nekunzwisisa miganhu yesimba remagetsi, hunhu hwekuchembera, high-frequency dielectric properties, uye sensitivities yezvakatipoteredza, mainjiniya vanogona kusarudza tepi giredhi rakakodzera - kana kukumbira mhinduro dzakagadziridzwa - kudzivirira kutadza nguva isati yakwana.
Semugadziri akavimbika wePTFE akakwira-tembiricha tepi , Aokai inopa zvigadzirwa zvakagadzirirwa zvinoda kushandiswa kwemagetsi ekuisa mukati mePTFE yakavharidzirwa machira, PTFE conveyor belt, PTFE mesh bhandi, PTFE film tepi, uye PTFE fiberglass tepi..
Izvo zviri pamusoro apa zvinopihwa neJiangsu Aokai New Materials Technology Co., Ltd.
Kuti uwane yakadzama tekinoroji paramita, mhinduro dzemashandisirwo, uye masevhisi akagadziridzwa ezvigadzirwa zvedu zvakazara zvinosanganisira PTFE yakakwirira tembiricha tepi, PTFE yakakwira tembiricha mesh bhandi, isina musono fusing muchina bhandi, single-sided PTFE jira, tembiricha inotakura bhandi uye jira rinodzivirira kupisa fiberglass , ndapota taura nesu wakasununguka:
Isu tinonamatira kune bhizinesi uzivi hwehunyanzvi uye kutendeseka, uye takazvipira kupa yakavimbika-yekumira mhinduro uye ane kufunga masevhisi kune vese vatengi.
