Jiangsu Aokai New Materials, inyanzvi yekugadzira PTFE yakakwirira-yekushisa machira, inopa zvakadzama wongororo. Matt sanding kurapwa kunounza shanduko dzakakosha kune chimiro chepamusoro chePTFE high-temperature jira. Iyo inoshandura iyo yekutanga-inert, yekupedzisira-yakatsetseka pamusoro kuita inosungika, inonyoroveka nyore inoshanda pamusoro kubva pamativi matatu: yemuviri morphology, coating kuperera uye pamusoro pemakemikari mamiriro.
1. Microscopic Morphology: Kubva paMirror yakatsetseka kusvika kuRough Gully Texture
Iyo isina kugadziriswa pamusoro pePTFE yepamusoro-tembiricha jira inenge yakatsetseka pasi pemaikorosikopu, inoumbwa neinoenderera firimu ye melt-sintered polytetrafluoroethylene. Kurapa kwejecha kunoshandura zvakanyanya micro-morphology yayo:
· Kuwedzera kwakasimba kwehushasha hwepamusoro: Kugera jecha (mabhandi anokwenya, mabhurashi ewaya) kana kuputika kwejecha (corundum, chena fused alumina) inocheka nekukanganisa pamusoro, kuveza zvisingaverengeki zvisina kurongeka mikoro-grooves, makomba nenhongonya. Core roughness zviratidzo Ra (arithmetical zvinoreva kutsauka kwechimiro chakaongororwa) uye Rz (gumi-mapoinzi kureba kwekukanganisa) inowedzera zvakanyanya.
· Kuumbwa kwemakanika anchoring chimiro: Aya madiki-grooves haasi nyore makwara, asi 3D anopindirana zvimiro. Uyu ndiwo musimboti weiyo anchoring mhedzisiro: zvinonamira zvinopinda mukati meaya mapundu uye zvinorapa kugadzira kupindirana kwemuviri kune kunotevera kusungirirwa kana kupfekwa.
· Yakashandurwa kufanana kwepamusoro: Kuisa jecha kwakaringana kunopa kupera kwe matte. Kudzora kwakashata kwemaitiro kunokonzeresa nzvimbo dzine jecha (yakatetepa zvakanyanya) uye zvigamba zvisina sandara zvakatsvedzerera, zvichikonzera kusarongeka heterogeneous morphology.
2. Kupfekedza Kutendeseka: Kubva Kuenderera Kunoenderera Firimu kusvika Pakukuvadzwa, Yakafumurwa Substrate
Iyi ndiyo njodzi yakanyanya kuoma inoda kuomesesa kudzora maitiro, yakanangana neiyo musimboti sevhisi kuita kwechigadzirwa:
· Kutetepa kwePTFE layer: Sanding inzira yekubvisa zvinhu zvemuviri. Iyo PTFE yekupfekedza yejira-yepamusoro-tembiricha kazhinji inotangira pamakumi kusvika kumazana emamicrons gobvu. Kuwedzeredza jecha kunoderedza zvakanyanya ukobvu hwekuputira, kudzikisa simba re dielectric uye kemikari corrosion resistance service hupenyu.
· Njodzi yefiberglass yakafumurwa substrate (yakanyanya kukanganisa chimiro): Kana kukuya kudzika kwakapfuura ukobvu hwePTFE coating, jira repasi refiberglass rinobviswa, zvichikonzera kukanganisa kwakatevedzana:
1. Kurasikirwa kwechinhu chisina tsvimbo: Fibers dzegirazi dzakafumurwa dzinonamira nyore kune zvinhu;
2. Unyoro uye kupinza kwemakemikari: Mvura yemvura nemakemikari zvinopinda mumucheka kuburikidza necapillary chiito chegirazi fibers, zvichiita kuti delamination uye kukurumidza kuparara kwekuita;
3. Kuderera kwesimba remagetsi: Kupwanya kwegirazi fibers kunokonzera kudonha kwakapinza mukusimba kwejira rese.
· Chizvarwa che microcracks uye marara akaunganidzwa: Abrasive kucheka paPTFE inosanganisa brittle fracture uye ductile kubvarura, kugadzira microcracks uye burrs pamwe ne groove edges uye bottoms. Zvichakadaro, akabviswa PTFE machipisi anogona kudzoreredza dhipoziti zvakasununguka pamusoro, achigadzira zvitsuwa-zvakaita zvimiro zvakasununguka zvinokanganisa kuvimbika kwekupotera kana kusungirirwa.
3. Surface Chemical State: Kubva kuUltra-Inert kusvika kune Activated
Kunyangwe jecha richinyanya kurapwa kwemuviri, rinokonzerawo shanduko kune pamusoro pemakemikari zvimiro:
· Yakakwira pamusoro pesimba: Yakachena PTFE ine Ultra-yakaderera pamusoro pesimba (18–20 mN/m), ine mvura yekubata angle pamusoro pe108°. Mushure mekuita jecha, nzvimbo dzichangobva kuumbwa dzakakasharara uye macheni akatyoka mamorekuru anofumura kwechinguva nzvimbo dzine simba repamusoro, dzichisimudza simba repamusoro pamusoro pe40 mN/m. Madonhwe emvura anopararira nekunyorova pamusoro, achiratidza kwenguva pfupi hydrophilicity, inopera zvishoma nezvishoma nekufamba kwenguva.
· Kusuma kwenguva pfupi kwemapoka anoshanda epolar: High-energy grinding inokonzera maitiro pakati pekuputsika PTFE molecular cheni uye okisijeni / unyoro mumhepo, pakarepo kubudisa polar functional mapoka akadai carbonyl (C = O) uye hydroxyl (-OH). Aya mapoka anogonesa kusungirirwa kwemakemikari kune imwezve makemikari shanduko kana adhesive lamination.
Pfupiso yeZvakanganisika
Muchidimbu, mushonga wejecha wakakodzera unogadzira yunifomu, yakaomarara, yakagadziriswa micro-nano chimiro pajira rePTFE pasina kukuvadza pasi pefiberglass substrate.
· Shanduko yakanaka: Inogadzira mechaniki inopindirana mameseji kugadzirisa PTFE's inherent urombo adhesion dambudziko.
· Negative zvipingamupinyi: Inopira yepakutanga isiri-tsvimbo kuita, kutsvedzerera kwepamusoro uye kujeka, nenjodzi dzisingaperi dzekukuvara kwe substrate uye kupfupika kwehupenyu hwesevhisi.
Naizvozvo, musimboti weichi chiitiko chiri mukudzora kwakanyatso kudzika kwekubvisa zvinhu - iyo chete yepamusoro PTFE yekumusoro layer inobviswa, pasina kubata fiberglass reinforcement skeleton. Iro jira rakarapwa rinowanzo kutumirwa ku coating kana kubatanidza maitiro nekukasira kutora mukana wakakwana weiyo yakakwana activated surface state.
Izvo zviri pamusoro pehunyanzvi zvemukati zvinopihwa ne Jiangsu Aokai New Materials Technology Co., Ltd.
Kana iwe uchida kuwana tsanangudzo dzakadzama, mamiriro ekushandisa uye zvigadziriso zvakagadziridzwa zvechigadzirwa chedu chizere chepodfolio chinosanganisira PTFE yakakwirira-tembiricha jira, PTFE yakakwirira-temperature adhesive tepi, PTFE yakakwirira-temperature mesh bhandi, seamless kupisa kupisa bhandi, single-sided PTFE jira, yakakwirira-tembiricha inodzivirira pazasi inodzivirira girazi, tapota taura nesu pazasi-inodzivirira girazi.
