E kwesịghị ileghara ịka nká nke eriri Teflon anya

Teflon tubes bụ fluoroplastic tubes nke emere site na ihe polytetrafluoroethylene site na ịgwakọta, ime embrayo, ịpị oyi, ịgbanye na jụrụ oyi.

Teflon tubes nwere ihe mara mma:

① Ọnụ ọgụgụ esemokwu dị ala;

② Nguzogide corrosion: acid siri ike na nguzogide alkali, na ihe fọrọ nke nta ka ọ bụrụ kemịkalụ niile adịghị emeghachi omume (na elu okpomọkụ na fluorine na alkali metal mmeghachi omume), nwere ike iguzogide "Aqua regia" corrosion;

③ Nhicha onwe: polytetrafluoroethylene siri ike ịrapara na ya;

④ Enweghị ọkụ;

⑤ High okpomọkụ na-eguzogide: PTFE teflon ihe okpomọkụ nwere ike iru -70 ° C ~ 260 ° C;

⑥ Nnukwu Nguzogide: Teflon tube nwere nguzogide dị elu, arụmọrụ mkpuchi dị mma;

⑦ Mgbochi ịka nká: Teflon Tube na-arụ ọrụ mgbochi ịka nká dị mma, ogologo ndụ ọrụ.

A pụghị ileghara ịka nká nke eriri PTFE anya, a ga-ebelata arụmọrụ nke ngwaahịa mgbe ịka nká, ya mere, mmepụta nke mbubreyo, anyị ga-emejuputa usoro usoro iji gbochie.

A na-eji usoro ọgwụgwọ sọlfọ kpuchie teepu nrapado nke ngwaahịa Teflon tube. Enwere ike imeziwanye nguzogide okpomọkụ nke vulcanizate ya site na ibelata ma ọ bụ zere iji sọlfọ elemental, nke nwere ike ibelata ma ọ bụ wepụ polysulfide cross-linking ma na-emepụta otu sọlfọ ma ọ bụ disulfide cross-linking.

Ojiji peroxide dị mkpa iji nweta ezigbo nguzogide okpomọkụ, ebe ọ bụ na iji peroxide na-agwọ ọrịa na-emepụta carbon-carbon crosslinks bụ ndị na-ekpo ọkụ karị. Ekwesịrị itinye nlebara anya pụrụ iche na mgbakwunye ndị ọzọ mgbe ị na-eji peroxide. Dịka ọmụmaatụ, nhọrọ nke antioxidants kwesịrị ịdịkwu ike, n'ihi na ọtụtụ n'ime ha na-egbochi peroxide, vulcanization.

Na mgbakwunye, mgbe ị na-eji peroxide, belata ọnụ ọgụgụ ndị na-eju acid iji gbochie cations peroxide ka ọ ghara ire ere, na-ebute obere vulcanization nke eriri nrụgide dị elu (n'ụdị ike siri ike, modulus dị ala na ntọala mkpakọ dị elu). Ịgbakwunye ogige ndị bụ isi, dị ka zinc oxide ma ọ bụ magnesium oxide, ebe o kwere mee, nwere ike na-emekarị ka arụmọrụ nke peroxide dịkwuo mma. Ka nwere paraffin mmanụ mmetụta ka mma, chọrọ izere iji aromatic hydrocarbon mmanụ na ihe mgbaze.
