PTFE impregnation haina kugumira kune fiberglass jira. Ichi chinyorwa chinosuma 7 mamwe ma substrates - aramid, carbon fiber, PBI, porous simbi, graphite, asbestos (pased out), uye ceramic fillers - ine maitiro avo maitiro, zvakanakira, zvisingakwanisi, uye zvakakosha mashandisirwo.

Mucheka unofema zvikuru wePTFE wepamusoro-tembiricha unobatanidza zvinhu zvisina tsvimbo, kugadzikana kwekupisa, uye kupenya kwemhepo. Ichi chinyorwa chinoongorora mashandisirwo ayo akakosha mukuomesa machira, kugadzira chikafu, kugadzira komputa, zvemagetsi, pneumatic conveying, kuchengetedza kwezvakatipoteredza, uye zvekuvakisa.

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.

Ichi chinyorwa chinotsanangura kuti sei alkali-isina fiberglass jira riri iro rinofarirwa substrate yePTFE yakakwirira-tembiricha jira. Iyo inovhara kemikari kusungirirwa kuburikidza ne silane coupling agents uye akakosha emuviri zvimiro senge kugadzikana kwemafuta, kugadzikana kwedimensional, uye kuramba kwecorrosion - kuve nechokwadi chekuita kwenguva refu munzvimbo dzakaoma.

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.

Senyanzvi yekugadzira PTFE machira epamusoro-tembiricha, Jiangsu Aokai New Materials inokutora iwe kuti udzidze zvakawanda. Kazhinji, glue yakarapwa uye resin inogona kupepetwa kubva pamucheka wepamusoro wePTFE wepamusoro-tembiricha uye pasina chasara chasara. Zvisinei, chigumisiro ichi hachisi mhedziso. Iwo chaiwo
