Fluorine rọba bụ ụdị rọba sịntetịt nwere atom fluorine. Ọ nwere oke okpomọkụ na-eguzogide, nkwụsị oxidation, mmanụ na-eguzogide ọgwụ na ọgwụ. A na-ejikarị ya na ụgbọ elu, ụlọ ọrụ kemịkalụ, mmanụ ala, ụgbọ ala na ngalaba mmepụta ihe ndị ọzọ dị ka ihe mkpuchi, ihe na-eguzogide ọgwụ na ihe mkpuchi. Rọba sịntetịt nke nwere atom fluorine n'ụdị molekụla ya.
A na-egosipụtakarị ya site na ọnụọgụ nke atọm fluorine nke nkeji nwere fluorine na copolymer. Dịka ọmụmaatụ, fluororubber 23 bụ copolymer nke vinylidene fluoride na chlorotrifluoroethylene. Fluororubber na-eguzogide oke okpomọkụ, mmanụ na kemịkal corrosion.
Uru nke fluororubber:
1. Magburu onwe elu okpomọkụ eguzogide: ọrụ okpomọkụ ranges si - 60 ℃ ka 250 ℃. Nguzogide mmanụ dị mma: iguzogide mmanụ mmanụ ọkụ dị elu, mmanụ sulfur nwere sọlfọ, mmanụ hydraulic, mmanụ diester, silicate ester na mmanụ ndị ọzọ dị mma karịa rubbers ndị ọzọ.
3. Nguzogide dị oke egwu na-emebi emebi siri ike na oxidant siri ike; Nkwụsi ike ya na mgbasa ozi na-emebi emebi siri ike dị ka fuming nitric acid, sulfuric acid, hydrochloric acid, hydrogen peroxide na alkali etinyere dị mma karịa rubbers ndị ọzọ.
4. Ezigbo ihe eji arụ ọrụ, mkpuchi eletrik na nguzogide radieshon.
5. Ezigbo iguzogide oke agụụ.
Ngwa nke fluororubber:
1. Mgbe mmiri na mmiri na-emetụta roba fluorine ma ọ bụ mgbe okpomọkụ na-ebili, mgbanwe ahụ dị ntakịrị. Ọbụna ma ọ bụrụ na silicon dioxide nke na-emepụta site na obere ọkụ ọkụ ka bụ ihe mkpuchi, ọ na-eme ka ihe eletrik na-aga n'ihu na-arụ ọrụ, ya mere ọ dị mma maka ịmepụta wires, eriri na eriri ụzọ.
2. Enwere ike iji fluoroplastic tube maka ibufe na akara dị iche iche siri ike acid na alkali, uzuoku, ikuku ọkụ, mmanụ ọkụ na mmiri ndị ọzọ. Enwere ike iji ya maka ngwa ụlọ, ọkụ na ngwaọrụ ahụike; 3. Enwere ike ichebe nrụgide ọrụ nke fluororubber tube (0.5-3.0 MPa) site na nkwonkwo na mkpuchi mkpuchi igwe anaghị agba nchara.
4. A na-ejikwa eriri fluoroplastic maka jaket waya na gburugburu ebe ọrụ siri ike .;
5. Fluororubber nwere oke okpomọkụ dị elu na nguzogide corrosion, ma nwee aha eze nke roba. Enwere ike ịhazi ya n'ime tube roba, teepu nrapado, ihe nkiri, gasket, (framework) mmanụ akara, "O" mgbanaka, "V" mgbanaka, wdg, nke a na-ejikarị eme ihe na ụgbọ elu, ụgbọ ala, mmanụ ala, ụlọ ọrụ kemịkalụ, telecommunication, ngwá ọrụ na ubi ndị ọzọ.
Dị ka anyị niile maara, valvụ ọ bụla ga-eji dị iche iche akara ihe, dị ka ethylene propylene roba (EPDM), nitrile roba (NBR), polytetrafluoroethylene (PTFE), fluororubber (Viton), silicone roba (SEP), okpomọkụ na-eguzogide EPDM roba roba, cemented carbide, alloy ígwè.
