Lintho tse emisitsoeng (polytetrafluoroethylene e emisitsoeng)
Mokhoa oa eona o ka sehloohong oa ho etsa ke mokhoa oa ho hatella, ke hore, phofo e tšoeu ntle le tlatsetso e nyane, ebe e etsa ka mokhoa o hatellang, e sintering ka holim'a mocheso oa eona oa ho qhibiliha, ebe ka ts'ebetso e nepahetseng ea mochini ka lihlahisoa, lihlahisoa tsa moemeli bakeng sa poleiti, bar, tube. , filimi lihlopha tse 'nè.
Lisebelisoa tsa ho hasana (ptfe)
PTFE phofo e ntle e lokiselitsoeng ke mokhoa oa ho hasana oa polymerization ka kakaretso e bitsoa "phatlalatso".Ka lebaka la thepa ea fibrotic ea phofo ena e ntle, haholo-holo mocheso o ka holimo ho 20 ℃, ho kgothaletswa ho boloka, ho tsamaisa le ho kopanya thepa ka 5 ~ 10 ℃. .Mokhoa oa ho etsa mofuta ona oa thepa ke ho sebelisa moemeli ea thusang (hangata petroleum ether kapa peterole) le phofo ka mor'a ho kopanya tikolohong ea 24 ℃ kapa ho feta bakeng sa hoo e ka bang 24h (ho tlatsa phetoho ea mohato oa kristale) ebe o theha, ka piston extrusion forming, drying, burning.Mokhoa ona oa ho sebetsa o tsejoa ka hore ke peista extrusion, e tsejoang hape e le push.
Ka lebaka la ho hasana ha karoloana ea phofo e ntle, e arotsoe ka lihlopha tse 'maloa tsa litlhaloso, litlhaloso tse fapaneng li na le litšobotsi tse fapaneng tsa compression ratio.Compression ratio ea ka tlaase ho 100, e atisang ho sebelisoa ho hlahisa thepa e tala le tepi ea microporous; e sebelisetsoang ho hlahisa lihlahisoa tse khethehileng tse mahareng le tse kholo; 500 ~ 2000 ke karolelano ea compression e mahareng.2000 ~ 4400 ke lisebelisoa tse phahameng tsa compression ratio, thepa ena e loketse tlhahiso ea lerako le tšesaane la mohala o mosesaane, o ka tsoela pele bolelele bo boholo le tlhahiso e phahameng ea katleho.
Mokhoa oa ho tsebahatsa: phapang e kholo ke boholo ba likaroloana tse peli ha li tšoane.Thepa e emisitsoeng e mahoashe, thepa ea ho hasana e ntle.
