Nigute ushobora kunoza ubushyuhe bwa reberi?

Kurwanya gusaza gushyushye cyangwa gusaza ubushyuhe biragenda biba ngombwa, cyane cyane mubikoresha amamodoka aho ibice bya reberi bikoreshwa ahantu hatwikiriwe nubushyuhe bukabije bwibidukikije. Abakora ibinyabiziga bumvise bongerewe ingufu kugirango biyemeze kuramba kubice byabo bya reberi. Anaerobic ubushyuhe bwo gusaza hamwe nubushyuhe nubusaza bwikirere biratandukanye. Rubber ifite ubushyuhe bwiza, ariko ntishobora kwihanganira igitero cya ogisijeni.

Icyitonderwa: Izi protocole rusange ntishobora gukoreshwa kuri buri rubanza. Ikintu icyo aricyo cyose mubihinduka bishobora kunoza gusaza kwikirere cyangwa kurwanya ubushyuhe-gusaza bizagira ingaruka kubindi bintu, byaba byiza cyangwa bibi.

1. Perfluoroelastomer

Niba ibikoresho bya reberi bisabwa kugira ubushyuhe budasanzwe, ugomba guhitamo reberi nziza. Biravugwa ko gukoresha ubushyuhe bwa parfluoroelastomer bigera kuri 316 ℃.

2 re Rubber

Fluorine reberi FKM ifite imbaraga zo kurwanya ubushyuhe, kandi irashobora gukoreshwa mubushyuhe bugera kuri 260 ℃. Kugirango urusheho gushimangira ubushyuhe bwo hejuru bwa reberi ya fluor, ugomba guhitamo aside iboneye (aside aside), nka oxyde ya magnesium oxyde, oxyde ya magnesium oxyde, calcium oxyde, calcium hydroxide, zinc oxyde, n'ibindi. Muguhitamo bisphenol AF nka sisitemu yo kurunga, ubushyuhe bwo gusaza bwa reberi bizaba byiza. Ikoreshwa mumavuta ya moteri ikarishye, ubushyuhe bwo gusaza bwa ternary fluoroelastomer ikozwe muri fluoride ya vinylidene, tetrafluoroethylene na propylene iruta fluoroelastomer rusange. Ibi biterwa no gusimbuza hexafluoropropylene na propylene mugikorwa cya polymerisation.

3 、 HNBR

Urwego rwo hejuru rwa hydrogène, niko arushaho guhangana nubushyuhe bwa HNBR, kubera ko ntaho bihurira kabiri byuzuye kumurongo munini udahungabana. HNBR zimwe ziracyashobora guterwa na sulfure kuko ziracyafite imigozi ibiri idahagije. Ariko, nibiramuka hamwe na peroxide, kurwanya ubushyuhe bwikigo bizanozwa. Kuri reberi ya HNBR, TOTM irashobora gutanga ubushyuhe bwiza kuruta DOP kubera ihindagurika rito hamwe nuburemere buke bwa molekile ya plastike ya trioctyl.

4. Neoprene

Ubwoko bwa W-neoprene bufite ubukana bwiza bwo gusaza kurusha G-neoprene. Diphenylamine octanoate ni antioxydants nziza kuri neoprene, ishobora kunoza neza ubushyuhe.

5 、 EPDM

EPDM izakomeza kugira ubushyuhe bwiza kuri 125 ℃ nyuma ikwiye. Gukoresha peroxide volcanized EPDM, irashobora gutuma reberi irwanya ubushyuhe bwiza.

6 method Uburyo bwa viscosity vapor phase method EPDM

Ibirungo byinshi bya Ethylene hamwe na ultra-low viscosity vapor phase EPDM, birashobora kuzuzwa numubare munini wuzuza, kubera ibinyabuzima byinshi bya Ethylene, gutunganya ntibikenewe ko byinjira mugutunganya ikirere cyangiza ubushyuhe bwumusaza bitameze neza na resin, birashobora gutuma reberi ifite ibikoresho byiza byo gutunganya, bityo ubushyuhe nyabwo bwa reberi bukaba bwiza.

7 Irinde gukoresha resin nyinshi

Irinde kongeramo resin nyinshi ya reberi ikoreshwa mubushyuhe bwinshi.

8 powder Ifu ya Talcum

Muri EPDM hose ya rubber, usimbuze 40% yumukara wa karubone nifu ya talcum, ishobora kunoza ubushyuhe bwo gusaza bwa reberi. Ibyiciro bimwe byifu ya talcum bifite ibyiza byingenzi kuruta ibumba ryatunganijwe cyangwa ritavuwe muriki kibazo.

9 plastic Amashanyarazi menshi

Muri plasitike, plasitike nyinshi cyane irashobora gutanga ubushyuhe bwiza bwo gusaza kuruta plastike nkeya. Kuberako plastike ya viscosity nyinshi mubusanzwe ifite uburemere buke bwa molekile, ntabwo byoroshye guhindagurika, bityo guhagarara neza no kurwanya ubushyuhe bwiza.

10 Gufata kungufu amavuta yimbuto kuri neoprene

Kugirango neoprene igire imbaraga nziza, hakenewe amavuta ya canola kuko afite ubukonje buke, bigatuma reberi igira hystereze nkeya hamwe n’umuvuduko muke, bishobora gutuma reberi irwanya gusaza neza.

11 EV Sisitemu nziza ya EV / igice-cyiza cya SEV ya volcanisation

Muri sisitemu ikora neza cyangwa igice cyogukora neza, igipimo cya moteri yihuta na sulferi ni kinini, ni ukuvuga, 'kuzamura cyane na sisitemu yo hasi ya sulferi ', hamwe na 'sulfure ku mubiri ' aho kuba sulferi imwe, muri iyi sisitemu y’ibirunga, igipimo cy’umugozi umwe wa sulfuru hamwe n’ububiko bubiri bwa sulferi muri reberi y’ibirunga ni byinshi, kubera ko bihagaze neza muri ubwo buryo bwo guhumeka bwa sulfuru, ubwinshi bwa sulfure, hamwe n’uburinganire bwa sulfuru, umubyigano wa sulfure ni mwinshi, kubwibyo, ubushyuhe bwo guhangana nubushyuhe bwa reberi buratera imbere kandi ubukana bwo gusaza bukaba bwiza.

12 ox oxyde

Vulcanisation / sub-sulfuramide sisitemu ya volcanisation ya reberi, yuzuyemo okiside ya zinc nyinshi, irashobora guha reberi ibyiza byo gusaza ubushyuhe no kurwanya neza nyuma ya sulfuru.

13 、 Peroxide yanduye EPDM rubber

Muri peroxide vulcanized EPDM, ZMTI yatoranijwe nka antioxydeant, ishobora guha ibice byinshi modulus hamwe nubushyuhe bwo gusaza.
