INTANGIRIRO KU BURYO BWO GUKORA UMUYOBORO WA PTFE

Uburyo bwo gukoraUmuyoboro wa PTFEni: PTFE, ubufasha bwo gusohora → kuvanga → gukanda → kumisha → gukonjesha → gukonjesha → ibicuruzwa

Uburyo bwo gushushanya imiyoboro ya PTFE burimo uburyo bwo gusunika, uburyo bwo gusohora, uburyo bwo gusudira, uburyo bwo guhinda, uburyo bwo kuzunguza, nibindi, muri byo uburyo bwo gusunika ni bwo buryo bw'ingenzi. Muri rusange, hakoreshwa resin ya PTFE itambitse ifite ingano ya 500μm n'ubucucike bugaragara bwa 0.45gml ~ 0.55gml. Ku miyoboro mito y'umurambararo, koresha resin ifite igitutu kinini, naho ku miyoboro minini y'umurambararo, koresha resin ifite igitutu gito. Ubusanzwe, icyuma gikoresha ubutare bwa 200 na 260. Uburyo bwa kabiri bwo gutunganya imiyoboro ya PTFE bushobora gukora imiyoboro ya PTFE ishyuha, imiyoboro ya PTFE izunguruka, imiyoboro ya PTFE izunguruka, nibindi.

Umuyoboro wa Polytetrafluoroethylene ukozwe muri resin ya polytetrafluoroethylene itatanye ku bushyuhe bw'icyumba hakoreshejwe umuti wa organic solvent nk'inkunga yo gusohora, hanyuma ukamishwa ugatogoteshwa. Dukurikije umurambararo w'umuyoboro, ushobora kugabanywamo ubwoko bubiri: umuyoboro usanzwe n'umuyoboro muto. Umurambararo w'imbere w'umuyoboro usanzwe ni 4mm, naho umurambararo w'imbere w'umuyoboro muto ni munsi cyangwa ungana na 4mm.

Uburyo bwo gukora umuyoboro wa PTFE ni: PTFE, ubufasha bwo gusohora → kuvanga → gukanda → kumisha → gukonjesha → gukonjesha → ibicuruzwa.

Imiyoboro ya polytetrafluoroethylene ifite imbaraga nziza za mekanike. Imiyoboro ni imiyoboro igororotse, imiyoboro ifite ishusho ya V, impeta za piston, imiyoboro ya valve y'umupira, nibindi, bikozwe mu nkoni za PTFE, imiyoboro, n'ibice bya PTFE binyuze mu gukata cyangwa gukata, birwanya ingese, birwanya kandi ntibikongere amashanyarazi.

1. Imiyoboro ya Teflon muri rusange ikoresha uburyo bwo gukanda, kandi no gukanda plunger extrusion nabyo bishobora gukoreshwa. Resin iboneka hakoreshejwe uburyo bwa dispersion polymerization ishobora gukorwa hakoreshejwe paste extrusion na calendering.

2. PTFE ifite pH iri hagati ya 0-14 (usibye ibyuma bya alkali na fluorine byashongeshejwe mu gihe cy'ubushyuhe bwinshi n'umuvuduko mwinshi), ishobora kugira imbaraga nziza za mekanike hagati ya 100°C na 100°C.

3. Imiterere yihariye y'imikorere ni uko igitutu cyo gutegurwa gitandukana bitewe n'imiterere n'ingano y'igicuruzwa. Ariko akenshi gikoreshwa. Gupfunyika kwa Teflon ni 8-34.3MPa, naho resin ifite filler ni 29.4-93MPa. Ku bwoya bunini bufite ubunini bwa mm 600 mu cyerekezo cyo gukanda, haracyari igihe cyo gufata igitutu cy'iminota 20-30. Menya ko iyo ubushyuhe buri munsi ya 185°C. Imiyoboro ya Teflon izacika intege. Gasket ya PTFE nziza ni igipfukamunwa cyiza kitazahumanya ikintu icyo ari cyo cyose cyahuye nacyo kandi gishobora gukoreshwa cyane mu biribwa, mu buvuzi no mu zindi nganda.
