Isifinyezo Esiphezulu

I I-Ruspert composite washer drilling screw iyisikulufu sokuzibhoboza esiphambili esakhelwe ukuqiniswa kwensimbi-kuya-insimbi kanye nensimbi-kuya-ugodo ezindaweni ezingaphandle ezinolaka. Ngokuhlanganisa i-case-hardened steel screw body, iphoyinti lokubhoboza elenza isinyathelo esisodwa sokumba nokuthepha, kanye iwasha yokuvala uphawu ehlanganisiwe ye-EPDM, lo mndeni wesikulufa wakhelwe ukusebenza okude kokugqwala.

Ivikelwe ngabakwa I-Ruspert ceramic-organic anti-rust coating, izikulufu ziletha ku Amahora angu-1,000+ wokumelana nesifutho sikasawoti ngaphandle kokugqwala okubomvu - ezedlula kude izikulufu ezijwayelekile ezifakwe ngogesi. Lesi sihloko sichaza isakhiwo sesikulufu, ubuchwepheshe bokuvikela ukugqwala ngemuva kokumboza, idatha yokuhlola eqinisekisiwe yokulwa nokugqwala, kanye neziqondiso ezisebenzayo zokukhethwa nokufakwa kokufulela, ukuvala, namaphrojekthi okukhweza ilanga.

1. Yini I-Composite Washer Drilling Screw?

A isikulufu sokumba iwasha esiyinhlanganisela (esiphinde sibizwe ngokuthi isikulufu sokuzibhoboza esinewasha evalekayo ebophayo) iyisibopheli esiluchungechunge esenza imisebenzi emithathu ngesenzo sokushayela esisodwa: ukubhoboza, ukwenza intambo, nokuvala uphawu. Ngokungafani nezikulufa ezijwayelekile zokuzishaya, indawo yokubhoboza edidiyelwe isusa isidingo sokumba ngaphambili.

Iwasha yerabha ye-EPDM eshisiwe - eboshelwe kusivalo sensimbi esiphendulwe yinsimbi - iminyanisa endaweni yephaneli ukuze yenze uphawu oluqinile lwezulu, olungavuzi.

Ngamagama asobala: isikulufu esisodwa sithatha indawo ye-drill bit, isikulufu sokucofa, kanye newasha yerabha ehlukile - futhi sigcina ukugqwala namanzi emvula kuphele iminyaka.

Umndeni womkhiqizo ngokuvamile uhlanganisa:

I-Hex washer head (HWH) izikulufu zokubhola- izinga lemboni yokufulela
I-Countersunk (ikhanda eliyisicaba) izikulufu zokubhoboza- ngezinhlelo zokuphothula iziqu
Ipani / izikulufo zokumba ikhanda lenkinobho- okwensimbi yeshidi kanye namapayipi

2.I-Anatomy of the Screw

Isakhi	Izinto kanye Nomklamo	Umsebenzi
Ikhanda	Ikhanda lewasha le-Hex eline-flange ehlanganisiwe (noma i-countssunk)	Ukudluliswa kwe-torque ephezulu; i-flange ihambisa umthwalo wokubopha
Iwasha eyinhlanganisela	Irabha ye-EPDM ivuthelwe ku-zinc-plated / 304 ikepisi yensimbi engagqwali	Uphawu oluhambisana nesimo sezulu; ibamba ukudlidliza; Ukumelana ne-UV ne-ozone, −40 °C kuya ku-+120 °C isevisi
I-Shank & thread	I-case-hardened carbon steel (C1022A), intambo egoqiwe	Amandla aphezulu okwenza intambo; izintambo ezigoqiwe zandisa ukumelana nokukhathala
Iphoyinti lokubhoboza	Ithiphu yokubhoboza eqinile, i-HRC 55–60	Ibhola ngensimbi kuze kufike ku-6.0 mm ubukhulu ekusebenzeni okukodwa
Ukugqoka	Ruspert i-ceramic-organic composite coating	Impilo ende yokunqanda ukugqwala kanye nokuvimbela ukugqwala

Amazinga omkhiqizo: I-GB/T 15856.4 / I-DIN 7504K (i-hex flange head self-drilling screws); intambo nge-GB/T 5280 / ISO 1478.

I-3.Ruspert Coating: I-Ceramic-Organic Anti-Corrosion Technology

Ukuvikelwa kwesithiyo— ama-flakes ensimbi afana nepuleti adala indlela ehlukumezayo evimba amanzi, umoya-mpilo, nama-ion e-chloride ukuthi afinyelele engxenyeni engaphansi yensimbi.
Ukuvikelwa komhlatshelo- ingxenye ye-zinc igqwala ngokuthandwa kakhulu, ihlinzeka ngokuvikeleka kwe-galvanic (cathodic) noma ngabe ukumboza kuklwebhekile endaweni yokubhoboza noma kuma-thread crests.
Ayikho ingozi ye-hydrogen embrittlement- ngokungafani ne-electro-plating, i-Ruspert iyinqubo ye-non-electrolytic dip-spin, ngakho-ke akukho ukushaja kwe-hydrogen kwesikulufu esiqinile.
Ukuzinza kwe-Dimensional- ukujiya kwakha kuphela u-6–12 µm wogqinsi, ngakho imicu igcina igeji yayo futhi ihlangane kahle ngaphandle kokuphinda uthephe.

Uma kuqhathaniswa nokuqedwa okujwayelekile kwesikulufu, u-Ruspert uhlala esigabeni esiphezulu sokuvikela ukugqwala okungabizi kakhulu:

Qeda	Isifutho Sikasawoti Esijwayelekile siye KuRust Ebomvu (ISO 9227 / ASTM B117)	Izindleko Ezihlobene	Amanothi
I-zinc emhlophe / eluhlaza okwesibhakabhaka	24–72 h	Phansi	Ukusetshenziswa kwangaphakathi endlini noma okomile kuphela
I-zinc plating ephuzi	72–120 h	Phansi–Phakathi	Ukukhanya kwangaphandle okukhanyayo
I-Mechanical galvanizing	240–400 h	Maphakathi	Kuhle kuma-fasteners asogwini
I-Dacromet / i-zinc flake (eyisisekelo)	480–720 h	Okumaphakathi–Phezulu	Izinketho zamahhala ze-Chrome ziyatholakala
I-Ruspert 500	500 h, akukho ukugqwala okubomvu	Okumaphakathi–Phezulu	Ibanga elijwayelekile lokufulela ngaphandle

4. Isiphetho

Okokuqinisa isikulufu sangaphandle lapho ukugqwala kuyisitha, i I-Ruspert composite washer drilling screw inikeza inhlanganisela eyivelakancane: i-drill-point convenience, i-EPDM sealing, kanye nobuchwepheshe be-ceramic-organic anti-corrosion obulinganiselwe kumahora angu-1,000+ wokukhuthazela kwesifutho sikasawoti. Inweba impilo yesevisi yejoyinti eliqinisiwe ukuze lifane - futhi ngokuvamile lidlule - isistimu yokufulela noma yokuvala, ukusika imijikelezo yokulungisa kanye nezindleko eziphelele zobunikazi.

Ngemininingwane yedatha yezobuchwepheshe, imibiko yokuhlolwa kwesifutho sikasawoti, kanye nokucaciswa kwesikulufu ngokwezifiso, xhumana nethimba lethu lokuthekelisa.

Okwedlule. Okulandelayo.
