Executive Summary

The Ruspert composite washer pobowola screw ndi pulani yodziboolera yokhayokha yopangira zitsulo kuchokera kuzitsulo kupita kuzitsulo komanso zomangira zitsulo ndi matabwa m'malo akunja ankhanza. Pophatikiza zitsulo zolimba zolimba zolimba, pobowola zomwe zimabowola sitepe imodzi ndikugogoda, ndi bonded EPDM composite sealing washer, banja la screw ili limapangidwira ntchito yayitali yolimbana ndi dzimbiri.

Kutetezedwa ndi Ruspert ceramic-organic anti- dzimbiri zokutira, zomangira zimaperekedwa mpaka Maola 1,000+ osakanizidwa ndi kupopera mchere opanda dzimbiri lofiyira - zomangira zomangira zomangika bwino kwambiri. Nkhaniyi ikufotokoza mawonekedwe a screw, ukadaulo woteteza dzimbiri kuseri kwa zokutira, deta yotsimikizika yolimbana ndi dzimbiri, ndi kusankha kothandiza ndikuwongolera pakukhazikitsa denga, zotchingira, ndi mapulojekiti oyika dzuwa.

1. Kodi Screw Drilling Screw Composite Washer Ndi Chiyani?

A composite washer pobowola screw (yomwe imatchedwanso zomangira zodzibowola zokhala ndi makina osindikizira) ndi chomangira cha ulusi chomwe chimagwira ntchito zitatu ndikuyendetsa kumodzi: kubowola, kupanga ulusi, ndi kusindikiza. Mosiyana ndi zomangira wamba zodzigudubuza, malo obowola ophatikizika amachotsa kufunikira koboola kale.

Chotsukira mphira cha EPDM chowombedwa - chomangika ku kapu yachitsulo yomangika - imakanikiza pamwamba pake kuti ipange chisindikizo chosagwirizana ndi nyengo, chomwe sichingatayike.

M'mawu omveka bwino: wononga imodzi imalowa m'malo mwa chobowola, chobowola, ndi chotsukira chala chapadera - ndipo chimasunga dzimbiri ndi madzi amvula kwa zaka zambiri.

Banja lazogulitsa limakhala ndi:

Zomangira za hex washer (HWH) pobowola- muyezo wamakampani ofolera
Countersunk (lathyathyathya mutu) kubowola zomangira- kwa ntchito zomaliza
Pan / batani mutu kubowola zomangira- kwa pepala zitsulo ndi ductwork

2.Anatomy of the Screw

Chigawo	Zofunika & Mapangidwe	Ntchito
Mutu	Hex washer mutu wokhala ndi serrated flange (kapena countersunk)	High torque kufala; flange amagawa clamping katundu
Wochapira kompositi	EPDM mphira vulcanized kwa zinki-yokutidwa / 304 zosapanga dzimbiri kapu	Chisindikizo chopanda nyengo; imatenga kugwedezeka; Kulimbana ndi UV ndi ozoni, −40 °C mpaka +120 °C ntchito
Shank & thread	Chitsulo cholimba cha carbon (C1022A), ulusi wokulungidwa	Mphamvu yapamwamba yopanga ulusi; ulusi wopindidwa umawonjezera kutopa
Drill point	Kubowola kolimba, HRC 55-60	Amabowola muzitsulo mpaka 6.0 mm wandiweyani pa ntchito imodzi
Kupaka	Ruspert zokutira za ceramic-organic composite	Anti-dzimbiri moyo wautali komanso anti-corrosion chotchinga

Miyezo yazogulitsa: GB/T 15856.4 / Chithunzi cha DIN7504K (zomangira za hex flange mutu kudzibowolera); ulusi pa GB/T 5280 / ISO 1478.

3.Kupaka kwa Ruspert: Ceramic-Organic Anti-Corrosion Technology

Chitetezo chotchinga- zitsulo zokhala ngati mbale zimapanga njira yopweteka yomwe imatchinga madzi, okosijeni, ndi ma chloride ions kuti afikire gawo lapansi lachitsulo.
Chitetezo cha nsembe- chigawo cha zinki chimawononga kwambiri, kupereka chitetezo cha galvanic (cathodic) ngakhale zokutira zitakandwa pamalo obowola kapena ulusi.
Palibe chiopsezo cha hydrogen embrittlement- mosiyana ndi electroplating, Ruspert ndi njira yopanda electrolytic dip-spin, kotero palibe kukwera kwa haidrojeni kwa thupi lolimba la screw.
Dimensional bata- zokutira zimangopanga makulidwe a 6-12 µm, kotero ulusi umasunga geji yake ndikulumikizana bwino popanda kugogodanso.

Poyerekeza ndi zomangira wamba, Ruspert amakhala pamwamba pachitetezo cha dzimbiri chotsika mtengo:

Malizitsani	Utsi Weniweni Wamchere ku Rust Wofiira (ISO 9227 / ASTM B117)	Mtengo Wachibale	Zolemba
White / blue zinc plating	24-72 h	Zochepa	Gwiritsani ntchito m'nyumba kapena m'kati mouma kokha
Yellow zinc plating	72-120 h	Low-Medium	Kuwala panja
Mechanical galvanizing	240-400 h	Wapakati	Zabwino kwa zomangira zam'mphepete mwa nyanja
Dacromet / zinc flake (zoyambira)	480-720 h	Wapakati-Wapamwamba	Zosankha zopanda Chrome zilipo
Mtengo wa 500	500 h, palibe dzimbiri lofiira	Wapakati-Wapamwamba	Standard panja Zofolerera kalasi

4. Mapeto

Kwa zomangira panja pomwe dzimbiri ndi mdani, ndi Ruspert composite washer pobowola screw imapereka kuphatikiza kosowa: kubowola-posavuta, kusindikiza kwa EPDM, ndi ukadaulo wa ceramic-organic anti-corrosion adavotera maola 1,000+ akupirira kupopera mchere. Imakulitsa moyo wautumiki wa cholumikizira chomangika kuti chifanane - ndipo nthawi zambiri chimakhala chotuluka - denga kapena zotchingira palokha, kudula kuwongolera komanso mtengo wathunthu wa umwini.

Pama data aukadaulo, malipoti oyesa kupopera mchere, ndi ma screw makonda, lumikizanani ndi gulu lathu lotumiza kunja.

Zam'mbuyo. Kenako.
