PTFE pamusoro pekurapa kwekubatanidza adhesion inoshandisa nzira mbiri huru: kunyungudika kwepamusoro-kunyunguduka (yepamusoro-soro yemamiriro ekunze, 9.5 MPa simba rine coupling agent, asi inobudisa magasi ane chepfu) uye sodium-naphthalene etching (5 MPa pakarepo kunamatira, nhete 24-48 awa hwindo, tsvina ine ngozi). Sarudza zvichibva pakutonga kwezvakatipoteredza uye kwenguva yakareba vs.

Kuchenesa uye kugadzirisa kwakakodzera kunowedzera hupenyu hwePTFE high-temperature jira. Kuchenesa mushure mekushandisa uye mushure mekutonhora. Shandisa mabhurashi akapfava, simbi dzisina divi, kana doro kuitira tsvina. Usamboshandisa yakasimba asidhi/alkalis, bleach, kana metal scrapers. Yenguva dzose silicone mafuta lubrication inoderedza kupfeka. Tevedzera nhungamiro idzi kudzivirira kukuvadzwa kwejasi.

PTFE high-temperature tepi ine kushomeka kwekudzivirira kune ionizing mwaranzi. Pakungoratidzwa kwe1 kGy gamma, simba rekusimba rinodonha kusvika ~ 25% yepakutanga. Inokodzera chete kune yakaderera-dose nharaunda (chikafu / chekurapa sterilization <10 kGy). Kune indasitiri yenyukireya kana spacecraft, shandisa polyimide kana PEEK pachinzvimbo.

Kuedza PTFE emulsion quality kunosanganisira zvitanhatu zvakakosha zviratidzo: yakasimba content (60±2% per T/FSI 067-2021), pH (9.0-11.0), particle size distribution (laser diffraction/DLS), viscosity (12-30 mPa·s pa 25°C), kugadzikana (centrifugal, freeze-rthaw). Iri gwara rinofukidza akajairwa bvunzo nzira kune yega yega parameter.

Kune PTFE yepamusoro-tembiricha matepi pasi pekunyudzwa kwenguva refu, iyo PTFE substrate inoramba iine chemikemikari inert, asi iyo yekunamatira layer ndiyo isina simba. Mvura inopedza silicone PSA; mvura yemunyu inokurumidza kuita ngura. Kune makemikari ane hukasha, fluorosilicone kana perfluoropolyether adhesives - kana adhesive-isina PTFE tepi - inodiwa. Peel simba kurasikirwa kusvika ku40% mushure memaawa makumi mana nemasere mumvura.

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 high-temperature jira uye silicone jira zvese zvinoshandisa fiberglass jira sechigadziko asi chinosiyana mukupfeka zvinhu (PTFE resin vs silicone rubber). PTFE inokunda mukusabatisa, kusapfeka, uye makemikari kuramba kusvika 260°C. Silicone jira rinopa kuchinjika kwepamusoro, kuvharwa kwemagetsi, uye kudzivirira moto (kusvika 230 ° C). Sarudza zvichibva pane zvaunokoshesa.

PTFE yakakwira-tembiricha jira (PTFE membrane zvinhu) isarudzo yekutanga yekusimba kwekuvaka. Mabhenefiti akakosha: makore makumi matatu+ ehupenyu hwekunze, kuzvichenesa pamusoro (mvura inonaya inosuka tsvina), kutapurirana mwenje munyoro (6-13%), Chiyero chemoto cheKirasi A, uye simba rakaita sesimbi riri pasi pe1.5 kg/m². Inoshandiswa munhandare, nhandare dzendege, uye zvivakwa zvemifananidzo pasi rese.

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 kurwa, kusarira, uye kutadza kudhinda.
