Fiberglass weave pattern - plain, twill, kana satin - inonyanya kukanganisa PTFE high-temperature machira emhando. Satin weave inopa simba repamusoro rekubvarura (2-3x bani) uye kuchinjika, yakanakira kukotama. Plain weave inopa yakanakisa dimensional kugadzikana uye peel adhesion, inokodzera static application. Twill inoenzanisa zvivakwa zvese zvekushandisa zvakajairika.

Coating uniformity yePTFE high-temperature jira inotarirwa nezvinhu zvina: coating formulation (particle size 0.15-0.35 μm, viscosity, solid content), coating & sintering process (blade coating inosarudzwa kuti ifanane), substrate quality (weave pattern, pre-treatment), uye nzvimbo yekugadzira (20-25% R <60). Dip + blade yakasanganiswa maitiro anoyera kupinda uye kutsetseka kwepamusoro.

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 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 high-temperature jira inopa yakasarudzika kemikari kuramba, inoshingirira maasidhi akasimba, alkalis, organic solvents, uye magasi anoparadza. Ichi chinyorwa chinodonongodza zvinhu zvayo zvinoramba, zvisingakwanisi (simbi yakanyungudutswa yealkali, yakasimba fluorinating agents), uye zvinhu zvakakosha senge tembiricha, kutarisisa, uye kushushikana kwemagetsi.

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.

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.

Senyanzvi yekugadzira PTFE machira ekushisa kwepamusoro, Jiangsu Aokai New Materials anogovera ruzivo rwakakodzera indasitiri newe. Edge warping uye kudonha kubva kuPTFE yakakwirira tepi matepi haawanzo kukonzerwa nechinhu chimwe chete, asi mhedzisiro kubva kune yakasanganiswa mhedzisiro yekutadza kusarudzwa tepi,

Jiangsu Aokai New Material, mugadziri anotungamira wePTFE machira ekudziya kwepamusoro, anogovera ruzivo rwehunyanzvi: Mitsetse yakachinjika uye musiyano weruvara wegore mumucheka wePTFE wepamusoro-tembiricha chiratidzo chekusaenzana kwekuputira ukobvu uye kusaenzana kwekushushikana kwekushushikana. Kugadzira
