Maitiro ekugadziraChubhu yePTFEndeiyi: PTFE, rubatsiro rwekuburitsa → kusanganisa → kudzvanya → kuomesa → kusviba → kutonhora → chigadzirwa
Maitiro ekuumba machubhu ePTFE anosanganisira nzira yekusunda, nzira yekubvisa, nzira yehydraulic, nzira yekubatanidza, nzira yekumonera, nezvimwewo, pakati pazvo nzira yekusunda ndiyo nzira huru. Kazhinji, resin yePTFE yakapararira ine saizi yezvikamu zve500μm uye density inoonekwa ye0.45gml ~0.55gml inoshandiswa. Kune machubhu madiki edhayamita, shandisa resin ine compression yakakura, uye kune machubhu makuru edhayamita, shandisa resin ine compression diki. Mushonga wekusvina unowanzo sarudza 200 ne260 mineral spirits. Kugadziriswa kwechipiri kwePTFE tube kunogona kugadzira machubhu ePTFE anodziya, machubhu ePTFE spiral, machubhu ePTFE hydraulic, nezvimwewo.
Chubhu yePoltetrafluoroethylene inogadzirwa neresin yakapararira yepolytetrafluoroethylene patembiricha yemumba uchishandisa organic solvent sekubatsira pakubvisa tsvina, wobva waoma wozopiswa. Zvichienderana nedhayamita yechubhu, inogona kukamurwa kuita mhando mbiri: chubhu yakajairika uye chubhu diki. Dhayamita yemukati yechubhu yakajairika i4mm, uye dhayamita yemukati yechubhu diki isingasviki kana kuti yakaenzana ne4mm.
Maitiro ekugadzira chubhu yePTFE ndeaya: PTFE, rubatsiro rwekuburitsa → kusanganisa → kudzvanya → kuomesa → kusviba → kutonhora → chigadzirwa.
Machubhu ePolytetrafluoroethylene ane simba rakanaka remuchina. Machubhu aya magasket akatsetseka, magasket ane chimiro cheV, mhete dzepiston, magasket evharuvhu yebhora, nezvimwewo, zvakagadzirwa nematanda ePTFE, machubhu, nemaplates nekucheka kana kutenderedza, izvo zvinodzivirira ngura, zvinoramba uye hazvifambise mvura.
1. Machubhu eTeflon anowanzo tevedzera nzira yekumanikidza, uye plunger extrusion molding inogonawo kushandiswa. Resin inowanikwa nenzira yekupararira kwepolymerization inogona kugadzirwa nepaste extrusion uye calendering.
2. PTFE ine pH ye0-14 (kunze kwesimbi dzakanyungudutswa dzealkali nefluorine pasi pekupisa kwakanyanya uye kumanikidzwa kwakanyanya), izvo zvinogona kuva nesimba rakanaka remakanika pakati pe100°C ne100°C.
3. Mamiriro chaiwo ekuita ndeekuti kumanikidzwa kwekutanga kunosiyana zvichienderana nechimiro nehukuru hwechigadzirwa. Asi chinowanzo shandiswa. Kurongedza kwakarukwa kweTeflon i8-34.3MPa, uye resin ine filler i29.4-93MPa. Kune mvere hombe dzine ukobvu hweinenge 600mm munzira yekudzvanya, kuchine nguva yekubata kumanikidzwa ye20-30min. Cherechedza kuti kana tembiricha iri pasi pe185°C. Tubing yeTeflon inozopera simba. Pure PTFE gasket chigadzirwa chakachena chekuvhara chisingasvibise chero chinhu chachinosangana nacho uye chinogona kushandiswa zvakanyanya muzvikafu, mishonga nedzimwe nzvimbo.
