Iyo nzira yekugadzira yePTFE pombi ndeye: PTFE, extrusion aid → kusanganisa → kudzvanya → kuomesa → sintering → kutonhora → chigadzirwa
Kuumbwa kwePTFE mapaipi kunosanganisira kusunda nzira, extrusion method, hydraulic method, welding method, winding method, etc., pakati peiyo push method ndiyo nzira huru.Kazhinji, yakapararira PTFE resin ine particle size ye500μm uye inooneka density ye 0.45gml ~ 0.55gml inoshandiswa.Pamapaipi madiki dhayamita, shandisa resin ine kudzvanya kwakakura, uye pamapaipi mahombe dhayamita, shandisa resin ine kakudzvanya kadiki.Iyo yekusvina rubatsiro kazhinji inosarudza 200 uye 260 mineral spirits.Iyo yechipiri kugadzirisa yePTFE tubinginogona kugadzira PTFE kupisa-shrinkable tubing, PTFE spiral tubing, PTFE hydraulic tubing, nezvimwe.
Polytetrafluoroethylene chubhu inogadzirwa ne polytetrafluoroethylene yakaparadzirwa resin pakamuri tembiricha uchishandisa organic solvent se extrusion aid, yobva yaomeswa nekunyungudutswa.Zvinoenderana nedhayamita yepombi, inogona kukamurwa kuita marudzi maviri: yakajairika pombi uye micro pombi.Iyo dhayamita yemukati yechubhu yakajairwa ndeye 4mm, uye dhayamita yemukati meiyo micro chubhu idiki kana yakaenzana ne4mm.
Maitiro ekugadzira ePTFE pombi ndeiyi: PTFE, extrusion aid → kusanganisa → kudzvanya → kuomesa → sintering → kutonhora → chigadzirwa.
Mapombi ePolytetrafluoroethylene ane simba rakanaka remagetsi.Iwo gaskets gaskets flat, V-shaped gaskets, piston mhete, bhora valve gaskets, nezvimwewo, izvo zvinogadzirwaPTFE tsvimbo, machubhu, uye mahwendefa nemuchina kutendeuka kana kucheka, ayo ari corrosion resistant, Resistance uye isiri-conductivity.
1. Teflon pombi kazhinji anotora compression kuumba nzira, uye plunger extrusion molding inogona kushandiswa zvakare.Iyo resin inowanikwa nenzira yekuparadzira polymerization inogona kuumbwa nekuisa extrusion uye calendering.
2. PTFE ine pH kukosha kwe0-14 (kunze kwesimbi yakanyungudutswa yealkali uye fluorine pasi pekushisa kwepamusoro uye high pressure), iyo inogona kuva nesimba rakanaka remagetsi pakati pe100 ° C ne100 ° C.
3. Mamiriro ezvinhu chaiwo ekuti preforming pressure inosiyana nechimiro uye saizi yechigadzirwa.Asi kazhinji inoshandiswa.Teflon yakarukwa kurongedza ndeye 8-34.3MPa, uye resin ine filler ndeye 29.4-93MPa.Kune makushe makuru ane ukobvu hunosvika 600mm munzira yekutsikirira, kuchine kumanikidzwa kubata nguva ye20-30min.Cherechedza kuti kana tembiricha iri pasi pe185°C.Teflon tubing ichava brittle.Pure PTFE gasket chigadzirwa chakachena chekuisa chisimbiso chisingasvibise chero chinhu chainosangana nacho uye chinogona kushandiswa zvakanyanya mukudya, mushonga uye mamwe maindasitiri.
