Ni ukubera iki isahani ya zinc idasabwa imbaraga zikomeye? Kandi ni ubuhe buryo bundi bushobora gukoreshwa aho? Kurinda bolts na screw kurinda ruswa bitabangamiye imbaraga cyangwa umutekano.

Iyo ba injeniyeri bagaragaje imbaraga-zikomeye (Icyiciro cya 10.9, 12.9, cyangwa bihwanye na ASTM A325 / A490) kugirango bahuze imiterere, bategereje ibikorwa byinshi bitwara imitwaro. Ariko iyo kurinda ruswa nabyo bisabwa, instinzi isanzwe ni ukugaragaza gusa zinc galvanizing. Ihitamo rirashobora guteza akaga.

Ikibazo nikintu cyitwa hydrogène - uburyo bwo kunanirwa bucece bushobora gutera bolts kuvunika nta nteguza, iminsi cyangwa ibyumweru nyuma yo kwishyiriraho. Dore ibyo ukeneye kumenya, nibiki kurwanya ruswa ni umutekano kuri-tensile Kwizirika.

Akaga kihishe: Kwinjiza hydrogène

Mu gihe cya amashanyarazi, hydrogen atomike ikorwa nkibicuruzwa. Iyo bolts ifite imbaraga zingana hejuru ya 1.000 MPa (gukomera> 320 HV) ikurura iyi hydrogène mumashanyarazi yabo, ibisubizo ni ugutakaza. Bolt irashobora gutsinda igenzura ryiza, torque neza kurubuga, hanyuma kunanirwa gitunguranye munsi yumutwaro usanzwe.

Uku kunanirwa gutinda - hamwe na zeru ya plastike ya zeru kandi nta nteguza igaragara - ituma hydrogène yinjira muri imwe mu ngaruka ziteye amayeri mu bwubatsi. Kuri sock head cap screw, hex bolts, hamwe nizindi nzego zo hejuru Kwizirika ikoreshwa mubikorwa bikomeye-byumutekano (ibiraro, turbine yumuyaga, guhagarika imodoka), ingaruka zirashobora kuba mbi.

Ikintu cy'ingenzi: Ndetse no guteka nyuma yo gutekesha (hydrogène embrittlement relief) ntibishobora kwemeza gukuraho hydrogène mu cyiciro cya 10.9 na 12.9. Ibyago ntibigera bigabanuka kuri zeru.

Galvanizing Risk by Bolt Grade

Bolt Grade	Imbaraga	HE Risk	Icyifuzo
8.8	800 MPa	Hasi	Gutanga ibitekerezo biremewe
10.9	1.000 MPa	Hejuru	Koresha zinc flake
12.9	1.200 MPa	Birakomeye	Zinc flake cyangwa ibyuma bidafite ingese

Gallvanizing ishyushye itwara hydrogène nkeya kuruta amashanyarazi, ariko gufata aside mbere yo kuvura iracyinjiza hydrogene. Kubisabwa umutekano-mwinshi, ntabwo aribwo buryo bwiza bwo guhitamo.

Uburyo bwiza bwo kurwanya ruswa

Nigute ushobora kurinda imbaraga-zikomeye na imigozi kuva ingese iyo galvanizing iri kumeza? Dore ubundi buryo bwagaragaye:

Zinc Flake Coating (Dacromet / Geomet)

Gukoreshwa muburyo bwa tekinike - nta bwogero bwa aside, nta electrolysis, zero hydrogène. Itanga 600-1,000 + amasaha yo kurwanya umunyu. Icyiciro cya Grade 10.9 na 12.9 bolts, screw, na sitidiyo.

Guhitamo Byiza

Amashanyarazi ya Zinc

Ubukonje-busudira ibice bya zinc hejuru yihuta idafite amashanyarazi. Nta hydrogène ishobora guhura, ikwiranye na hex bolts nini cyane.

Nta ngaruka za hydrogène

Icyuma Cyuma

A316 cyangwa A4 (316) ibyuma bitagira umuyonga hamwe na screw bitanga kwihanganira ruswa. Ibyiza kubidukikije byo mu nyanja, imiti, hamwe no hanze.

Igisubizo cyiza

PTFE / Igikoresho cya Fluoropolymer

Itanga imiti irwanya imiti hamwe no guterana amagambo. Akenshi uhujwe na zinc munsi kugirango irinde ruswa kwangirika kwinganda.

Gukoresha Umwihariko

“Igikoresho cyiza cyo kurwanya ruswa kirinda ishoramari ryawe. Umuntu mubi arashobora kubisenya.”

- Itsinda ryubwubatsi bwa FUJINRUI

Guhitamo Igisubizo Cyiza

Iyo uhitamo an kuvura ruswa kubwawe Kwizirika, tekereza kuri ibi bintu:

Bolt Grade- Icyiciro cya 8.8 na munsi yacyo birashobora gukoresha galvanizing. Kuri 10.9 no hejuru, burigihe hitamo zinc flake cyangwa ibyuma bidafite ingese.
Ibidukikije- Ikirere cyo mu nyanja n’inganda gisaba amasaha menshi yo gutera umunyu. Ububiko bwa geometrikena ibyuma bitagira umuyonga indashyikirwa hano.
Gusaba- Imodoka, ingufu z'umuyaga, hamwe nibyuma byubaka bisaba ibyago bya hydrogène. Sisitemu ya plaque na zinc flake sisitemu nibisanzwe.
Igiciro va Imikorere- Zinc flake coatings (Dacromet, Geomet) itanga uburinganire bwiza bwo kurwanya ruswa, umutekano wa hydrogène, nigiciro kuri benshi umutwaro uremereyePorogaramu.

Icyo Ibi Bisobanura Amasoko

Kubitsinda ryamakipe naba injeniyeri b'imishinga, inzira irasobanutse: ntuzigere usubiramo galvanizing kubakomeye-bakomeye. Buri gihe ugaragaze urwego rwa bolt nibidukikije, kandi ukore hamwe nuwawe uruganda rwihuta guhitamo sisitemu yo gukuraho ikuraho hydrogène.

Kuri FUJINRUI, dukora anti-ruswa, imigozi, na Kwizirika hamwe na Dacromet, Geomet, imashini zinc, hamwe na PTFE - bikwiranye nibisabwa hamwe nibidukikije. Buri cyiciro kigeragezwa kubwimbaraga za mashini no kurwanya ruswa mbere yo koherezwa.
