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 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.

PTFE high-temperature jira inopa yakasarudzika makemikari kuramba, inoshingirira maasidhi akasimba, alkalis, organic solvents, uye magasi anoparadza. Ichi chinyorwa chinodonongodza zvinhu zvaro zvinopokana, zvinogumira (akanyungudutswa alkali simbi, yakasimba fluorinating agents), uye zvakakosha zvinhu zvakaita setembiricha, kutarisisa, uye kushushikana kwemagetsi.

Senyanzvi yekugadzira machira ePTFE epamusoro-tembiricha, Jiangsu Aokai New Materials inokupa ruzivo rwehunyanzvi. Chinangwa chikuru chefiberglass pamusoro kurapwa ndechekuvaka bhiriji remamorekuru pakati peinorganic fiberglass uye organic PTFE, kuitira kuti vagadzirise ivo inherent inc.
