Kune PTFE yakakwirira-tembiricha tepi inoshandiswa muabrasive sliding friction applications, standard non-stick uye heat resistance hazvina kukwana. Nzira dzakakosha dzekusarudza: Taber abrasion loss (<15 mg/1000 cycles), yakazadzwa yakagadziridzwa PTFE coating (carbon/graphite/MoS₂), PV limit data, substrate simba (≥200 N/cm), uye mating surface roughness (Ra 0.2-0.4 μm). Kudzivirirwa kwakaringana kwemupendero uye kubatana kwakazara kwakakosha kune hupenyu hurefu.

Musoro wekupedzisa maajenti akaiswa kune jira refiberglass pamberi pePTFE coating yakakosha kune yekupedzisira PTFE yakakwirira-tembiricha machira kuita. Organosilane coupling agents inogadzira mabhiriji mamorekuru pakati peinorganic glass fiber uye organic PTFE, inowedzera masvuura simba kubva pa<2 N/cm kusvika 4-8+ N/cm. Kurapa kwakakodzera kunowedzerawo kupisa kupisa (260 ° C +), dielectric performance, uye makemikari kuramba. Mucheka usina kurapwa unotungamira kune delamination, kutubukira, uye hupenyu hupfupi hwesevhisi.

Warp uye weft density yefiberglass jira rinotarisa PTFE yakakwirira-tembiricha machira kuita. Yakakwira density inowedzera simba rekusimba uye kutsvedzerera kwepasi asi inoderedza simba rekubvarura (inverted U-curve), kuchinjika, uye kupinda mukati. Optimal density zviyero kupinza, kuramba kubvarura, kuchinjika, uye kupera kwepamusoro. Low density inokodzera kubhenda kunochinja; high density ye-non-stick uye insulation.

PTFE substrate inogara munyu pfapfaidzo inoshingirira (kunwa mvura <0.01%). Zvisinei, kushanda kwematepi kunoenderana nemhando yekunamatira: silicone PSA inomira munzvimbo dzegungwa (500-1000h salt spray test,> 80% peel retention); acrylic PSA inokundikana. Kurapwa kwakaringana kwepamusoro, kushandiswa kwebubble-isina, uye kuvharwa kwemupendero nesilicone sealant kwakakosha pakuvimbika kwenguva refu pamapuratifomu emahombekombe uye ngarava.

Calendering - kudzvanya PTFE-yakavharwa jira pakati peanopisa girazi rollers pa360-380 ° C - zvinonyanya kushandura morphology yepasi, kuburitsa zvimiro, kusamira, uye mashandiro emuchina. Iyo inoderedza roughness kubva kuRa 0.5-1.0 μm kusvika ku <0.05 μm, inovhara pinholes, inovandudza kupfeka kusagadzikana, asi inoderedza simba rekubvarura uye kushanduka. Zvakakosha pakusunungura liners uye magetsi ekudzivirira.

Fiberglass weave pattern - plain, twill, kana satin - inonyanya kukanganisa PTFE high-temperature machira zvivakwa. 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.

PTFE fiberglass tepi inoda zvitupa zvitatu zvakakosha zvekuchengetedza: UL (kuchengetedzwa kwemagetsi nemurazvo), FDA (kuenderana kwechikafu), uye ISO 9001: 2015 (mhando yekutonga). Matepi akasimbiswa anopa kuita kwakafanana, hupenyu hwesevhisi hurefu, uye mutengo wakaderera wevaridzi kunyangwe mutengo wepamberi wepamusoro. Gara uchisimbisa zvitupa zvakananga nemasangano anoburitsa.

PTFE conveyor belts (Teflon belts) inovandudza mitsara yekugadzira zvokudya kuburikidza nemabhenefiti mana anokosha: hukuru husina-tsvimbo (inoderedza marara uye kunamatira), kushivirira kwekushisa kwehupamhi (-100 ° C kusvika 260 ° C inogonesa kubheka kutonhora), kuchenesa nyore uye kupikisa kwebhakitiriya (isina-porous surface, FDA inowirirana, uye kushandiswa kwehupenyu kwenguva refu). Inokodzera zvakabikwa, chikafu chakaomeswa nechando, chokoreti, uye zvinonamira zvigadzirwa.

PTFE high-temperature tepi inoshandiswa pamativi matatu ekurapwa kwemishonga: kudzivirira midziyo yekudzivirira (autoclave trays, heat-seal packaging), chiridzwa chepamusoro kurapwa (low-friction coating, electrical insulation), uye midziyo inoisirwa (vascular grafts, sutures). Biocompatibility inosimbiswa kuburikidza neISO 10993, uye FDA 21 CFR 177.1550 inogadza hwaro hwekuchengetedza zvinhu.

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.
