PTFE high-temperature tepi inoshandiswa mumapurogiramu ekutsvaga kwezvokudya inofanira kugara mukati memiganhu yakatsanangurwa yekushisa: ≤260 ° C kuti irambe ichishandiswa, ≤300 ° C kwepamusoro pepamusoro (maminitsi), uye isingambopfuuri 327 ° C (kuora). FDA neEU mirau haitsanangure nguva yakatarwa - nguva yakachengeteka yekubata inoenderana nekupisa uye inofanirwa kusimbiswa nemiedzo yekufambisa inoteedzera mamiriro chaiwo.

PTFE yakakwirira-tembiricha tepi inoda kuchengetedza kwakaringana kuchengetedza kunamatira kwayo, kuchinjika, uye kuburitsa kuita. Zvinodiwa zvakakosha zvinosanganisira kudzora tembiricha (10-30 ° C), humidity iri pasi pe60%, kudzivirira mwenje, kuparadzaniswa kwemakemikari, kuiswa kwakamira, uye kufefetedza. Tevera FIFO inventory management uye ongorora nguva dzose.

Kusarudza PTFE yakakwirira-tembiricha tepi ye 3D printer inopisa mubhedha inoda kutarisa pane zviratidzo zvina zvakakosha: kupisa kwekushisa (kusvika ku260 ° C +), fiberglass-reinforced substrate (0.18mm yakanaka), silicone adhesive inotsigira nepamusoro-soro, uye upamhi hwakakodzera / kushivirira. Gwaro iri rinokubatsira kuti udzivise kukanganisa, kusarira, uye kutadza kudhinda.

Iyo tembiricha yegirazi yekuchinja (Tg) yesilicone yekumanikidza-inonzwa inonamira yakatenderedza -120 ° C - yakadzikira zvakanyanya kupfuura acrylic adhesives. Iyi ultra-low Tg inochengeta PTFE yakakwirira-tembiricha tepi ichichinjika uye inonamira kunyange pa -70 ° C, ichidzivirira brittle kuputika uye kugonesa kunamatira kwakavimbika mune cryogenic application.

PTFE high-temperature tepi inogona kutsemuka kana kutsemuka pasi pekudzokorora kukotama uye kuvhura mamiriro. Ichi chinyorwa chinotsanangura maitiro ekudzivirira izvi kuburikidza nekwakakodzera substrate kusarudzwa (girazi faibha yakasimbiswa), yakakwana ukobvu (0.18mm seyakajairwa), silicone adhesive sarudzo, uye nzira dzekuisa dzakaringana.

Sarudzo yepepa rekuburitsa kana firimu substrate uye mumiriri wekuburitsa zvinokanganisa kugadzikana kwekuchengetedza uye peeling kuita kwePTFE yakakwirira-tembiricha tepi. Ichi chinyorwa chinofananidza PET vs. kraft paper substrates uye silicone vs. fluorinated release agents, inokurudzira kusanganiswa kwakakwana kwezero-residue peeling uye kuvimbika kwenguva refu.

PTFE high-temperature matepi anoshandiswa zvakanyanya pakuvhara magetsi, asi high-frequency uye high-voltage mamiriro ezvinhu anokonzera njodzi dzakasiyana-siyana: kuparara kwemagetsi, kubuda zvishoma, kuchembera kwekushisa, kurasikirwa kwechiratidzo chepamusoro, uye kunzwa kwezvakatipoteredza. Chinyorwa chino chinotsanangura njodzi yega yega uye nzira yekuinzvenga nayo.

Ichi chinyorwa chinotsanangura nzira yekudzivirira kusvibiswa uye kukanganisa kwekushanda kune iyo isina-adhesive side yePTFE high-temperature tepi panguva yekuputira. Mazano akakosha anosanganisira kudzora sosi (chaiyo yepamusoro kurapwa), kuzviparadzanisa nevamwe (mafirimu ekudzivirira, asiri-tsvimbo rollers, zoned drying), uye yakanatswa maitiro manejimendi.

Ndezvipi Zvitupa Zvandinofanira Kutsvaga muChikafu-Giredhi PTFE Tepi?Zviyedzo zvakanyanya kutariswa mune chikafu-giredhi PTFE adhesive tepi yekushandiswa kwekutengesa ndeye FDA kutevedza, NSF certification, uye ISO 9001:2015 quality management standards. Aya zvitupa anoita shuwa kuti iyo polytetrafluoro

Mamaneja mazhinji ekutenga zvinhu anoda kuita kwakanyanya kana vachitarisa sarudzo dzemaindasitiri anonamira. Ivo vanofanirwa kuziva mutsauko pakati pePTFE fiberglass tepi uye silicone tepi. Polytetrafluoroethylene layer inopa PTFE fiberglass tepi yayo huru isina-tsvimbo zvivakwa uku uchiruka fiberglass giv.
