PTFE haina kunamatira kune girazi fiber. Pasina kurapwa kwakakodzera kwepamusoro, iyo PTFE yekupfekedza PTFE jira rinopisa rinobvaruka sesokisi rakasununguka. Chakavanzika chiri mumashure ekupedzisa vamiririri - mishonga yemakemikari inoshandiswa kune fiberglass jira risati raputirwa.
Aya maajenti - kunyanya organosilane coupling agents - anoita semamorekuru mabhiriji, anosunga nekemikari iyo inorganic glass fiber kune organic PTFE. Sarudzo yemumiririri, kusungirira kwayo, uye nzira yekurapa inonyanya kuona simba repeel, kupisa kupisa, hupenyu hwekuchinja, uye dielectric kuita.
Aokai PTFE yakagadziridza pamusoro pekupedzisa chemistry mukati memakumi emakore ekugadzirwa. Gwaro iri rinotsanangura zvikamu zvikuru zvevamiririri, maitiro azvo pazvivakwa zvakakosha, uye nei kurapwa kwakakodzera kusingataurwi kwejira remhando yepamusoro rePTFE.
Zvikamu Zvikuru zveSurface Finishing Agents
Isati yaiswa PTFE, jira refiberglass rinowanzo kubviswa wax uye kuvhurwa kwepasi. Kemikari yekurapa inorongwa nemakemikari senge pazasi:

Kemikari kusungirirwa + kubatwa kwemuviri; Coating inopikisa peeling pasi pekudzokorora kuchinjika uye kuvhunduka kwekushisa |
Yakanyanya kukanganisa: Simba rePeel ndiyo inogadzirisa yehupenyu hwekuneta uye delamination kuramba.
2. Heat Resistance & Thermal Kugadzikana
High-temperature-resistant coupling agents (ine benzene kana heterocyclic structures, eg, mamwe epoxy & acyloxy silanes) inoshingirira 260°C inoenderera mberi nepamusoro pepamusoro>300°C – inoenderana nePTFE sevhisi.
Zvakajairwa organic additives zvinowora patembiricha yakakwira → interfacial voids, yellow discoloration, coating spalling.
Chirevo chekushandisa: Kune yakanyanya-tembiricha maapplication, ita shuwa kuti iyo yekupedzisa mumiririri pachayo yakagadzikana nemafuta, kwete chete PTFE coating.
Uniform silane modification inowedzera PTFE emulsion kupararira uye kunyorova pamusoro pefiber pamusoro → inoenderera compact coating ine mapinhole mashoma uye microcracks → yakakosha pakuputsika kwemagetsi uye kugona kuvhara.
Hygroscopic kana ion-yakasvibiswa kurapwa makemikari anosimudza dielectric kurasikirwa. Yakakwirira-kuchena silane inogamuchirwa kune premium-giredhi PTFE jira kuderedza kusachena kupindira.

Kiyi yekutora: Surface yekupedzisa mumiriri ndiyo yakakosha tekinoroji yePTFE yakakwirira-tembiricha yekugadzira machira. Inotongwa ne organosilane coupling agents, makemikari aya anovaka molecular link pane inorganic-organic interface kugadzirisa PTFE yakashata yekunamira kune fiberglass. Ivo vanonyanya kuona simba repeel, flex lifespan, heat resistance, magetsi ekudzivirira, uye makemikari inertness.
Muchidimbu , iyo yekumusoro yekupedzisa agent yakaiswa kune fiberglass jira pamberi pePTFE coating haisi diki ruzivo - ndiyo hwaro hwePTFE yepamusoro-tembiricha machira kunaka. Organosilane coupling agents (amino, epoxy, fluorinated) inogadzira mabhiriji akakosha mamorekuru pakati pegirazi faibha nePTFE, inosimudzira masvuura simba kubva pa<2 N/cm kusvika 4-8+ N/cm. Kurapa kwakakodzera kunowedzerawo kudzivirira kupisa (260 ° C+), kupfekedza compactness, dielectric performance, uye chemical resistance.
Paunenge uchisarudza PTFE jira rekuda maapplication, bvunza nezve iyo yepamusoro yekupedzisa chemistry - inokanganisa zvakananga hupenyu hwesevhisi uye kuvimbika. Dzivisa kusarapwa kana kusabatwa zvakanaka ma substrates, ayo anozo delaminate pasi pekupisa uye mechanical stress.
Unoda jira repamusoro-soro rePTFE rakakwenenzverwa pamusoro pekupedzisa? Aokai PTFE inoshandisa epamberi coupling agent maumbirwo ekunamatira kwepamusoro uye kusimba. Bata nesu nezvido zvako zvekunyorera.
