Fiberglass fabric thermal shrinkage ndiyo inonyanya kukonzera PTFE tepi dimensional kusagadzikana. Pa PTFE sintering tembiricha (360-400 ° C), zvakasara zvekuruka kushushikana kunoburitswa. Kana isingadzoreki, jira rinopera; kana ikadziviswa, kushushikana kwakadzikama kunovharirwa mukati, zvichiita kuti gare gare kupera panguva yekunamatira kurapa (150-200 ° C) uye kupera-kushandiswa kupisa. Mhinduro: shandisa pre-heat-set fiberglass ne <0.5% shrinkage pa 400 ° C, kubvisa kushushikana kwakasara kusati kwavhara.

Thickeners muPTFE emulsion inoshanda mabasa mana akakosha: kumisa kudzikamisa (kunodzivirira kugadzika kwe dense PTFE particles), shear-kuonda maitiro (yakakwirira viscosity pakuzorora, yakaderera pasi pekushungurudzika kwekuvhara nyore), kupinza kudzika kwekudzora (inodzora resin kurodha pamucheka wefiberglass), uye kufanana kwefirimu (inodzivirira kuputika panguva yekuomesa). Chinodiwa chakakosha: makobvu anofanira kuora zvachose pa ~ 380 ° C sintering tembiricha, achisiya zero madota asara kuti achengetedze kuchena kwekupfeka uye kuvharwa kwemagetsi.

Aokai PTFE yakatanga mutsara wayo uzere wechigadzirwa paAPFE Shanghai 2026 (Booth 6T602, Hall 6). Zvigadzirwa zvinoratidzwa zvinosanganisira matepi efiberglass-akasimbiswa ePTFE, mafirimu ePTFE akachena, anti-static mamakisi, uye mabhandi ekutakurisa-anovhara chikafu, PV lamination, lithium mabhatiri, zvemagetsi, uye kurongedza. Chiratidziro chinoenderera kusvika munaJune 26. Zvigadzirwa zvose zvinotsigira zvakatemwa zvetsika.

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 zvichienderana nekutonga kwezvakatipoteredza uye kwenguva yakareba vs.

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.

Kuisa PTFE tepi yepamusoro yekushisa zvakasimba panzvimbo yakakomberedzwa uye isina kujairika isina mafuru uye kumucheto kuchinjika, chirongwa chakamisikidzwa chekushanda chakakosha, kusanganisira kunyatsogadzirisa substrate pretreatment, hunyanzvi hwekushandisa uye matanho akakodzera ebetsero. Pakati pavo, substrate pretreatment ndiyo inonyanya kukosha nhanho, iyo inosarudza nezve 70% yekupedzisira yekunamatira maitiro.

Tichipesana nemashure ekuwedzera kuomesera mirau yezvakatipoteredza, PFOS/PFOA-yemahara PTFE emulsion chigadzirwa chakakwidziridzwa chakagadzirwa kutsiva yechinyakare PFOA-ine polymerization maitiro. Iyo inochengetedza iyo yakakosha zvivakwa zvePTFE uku ichiwedzera zvakanyanya kushamwaridzana kwezvakatipoteredza uye kuchengetedzwa kwehutano.

Iyo yekupisa yekuwedzera coefficient yePTFE yakakwirira tembiricha machira haisi iyo yakatarwa kukosha. Inoramba yakadzikama pakupisa kwekamuri kusvika ku100 ° C (inenge 0.5×10⁻⁵/°C), asi inokwira zvakanyanya pasi pemamiriro ekushisa.

Senyanzvi yekugadzira PTFE jira rekushisa kwepamusoro, Jiangsu Aokai New Materials anogovera maitiro epakati ekutsemura. Kuti udzivise maburrs, delamination uye dimensional kutsauka panguva yekutsemura, zvakakosha kuti udzore zvakarongeka zvinhu zvina zvakakosha: maturusi ekucheka, zvishandiso, mbishi zvinhu.

Semugadziri wepakutanga wePTFE matepi ekupisa kwepamusoro, Jiangsu Aokai New Materials pano inotsanangura mabatiro enzira dzekutonhodza uye mwero wekutonhodza pakuita kweakaporeswa PTFE epamusoro-tembiricha matepi.I. Essence yePTFE Crystallization Hunhu uye Kutonhora Mwero RegulationThe PTFE su.
