Isishwankathelo soLawulo

I I-Ruspert composite washer yokomba isikrufu sisikrufu sepremiyamu sokuzibhomba esenzelwe intsimbi ukuya kwintsimbi kunye nentsimbi ukuya kumaplanga kwindawo endlongondlongo yangaphandle. Ngokudibanisa i-case-hardened steel screw body, indawo yokubhola eyenza inyathelo elinye lokomba kunye nokucofa, kunye iwasha yokutywina ehlanganisiweyo ye-EPDM, le ntsapho screw yakhelwe ixesha elide anti-rust ukusebenza.

Ikhuselwe yi Ruspert ceramic-organic anti-rust ukutyabeka, izikrufu zihambisa ukuya Iiyure ezingama-1,000+ zokuxhathisa isitshizi setyuwa ngaphandle komhlwa obomvu - ukodlula kakhulu izikrufu eziqhelekileyo ze-electro-plated. Eli nqaku lichaza ubume besikrufu, itekhnoloji yokukhusela umhlwa emva kwengubo, idatha eqinisekisiweyo yovavanyo lokulwa nomhlwa, kunye nokhetho olusebenzayo kunye nesikhokelo sofakelo lophahla, ukugquma, kunye neeprojekthi zokunyuswa kwelanga.

1. Yintoni iWasher eDirilling Screw ehlanganisiweyo?

A Iwasha edibeneyo yokomba isikrufu (esikwabizwa ngokuba sisikrufu sokuzibhora esinewasha etywiniweyo etywiniweyo) sisiqhoboshi esinemisonto esenza imisebenzi emithathu kwisenzo sokuqhuba esinye: ukugrumba, ukwenza imisonto, kunye nokutywina. Ngokungafaniyo nezikrufu eziqhelekileyo zokuzicofa, indawo yokudibanisa edityanisiweyo isusa imfuno yokugrumba kwangaphambili.

Iwashi yerabha ye-EPDM enevulcanized - edityaniswe kwintsimbi ebambekayo yentsimbi - ixinzelele kumphezulu wephaneli ukwenza imozulu-eqinile, itywina lobungqina bokuvuza.

Ngokucacileyo: esinye isikrufu sithatha indawo ye-drill bit, isikrufu sokucofa, kunye newasha yerabha eyahlukileyo - kwaye igcina irusi kunye namanzi emvula ngaphandle kweminyaka.

Usapho lwemveliso lubandakanya:

Intloko yewasha yeHex (HWH) izikrufu zokomba- umgangatho woshishino lokuphahla
I-Countersunk (intloko ethe tyaba) izikrufu zokomba— kwiinkqubo zokugungxula
Ipani / izikrufu zentloko yokomba iqhosha- kwi-sheet metal kunye ne-ductwork

2.I-Anatomy ye-Screw

Icandelo	Izinto eziphathekayo kunye noYilo	Umsebenzi
Intloko	Intloko yewasha yeHex eneflange exwebileyo (okanye i countersunk)	Ukuhanjiswa kwetorque ephezulu; i-flange isasaza umthwalo wokubamba
Iwasha ehlanganisiweyo	Irabha ye-EPDM ivulwe kwi-zinc-plated / 304 intsimbi engenasici	Isitywina esinemozulu; ifunxa ukungcangcazela; Ukumelana ne-UV kunye ne-ozone, −40 °C ukuya +120 °C kwinkonzo
I-Shank & thread	I-case-hardened carbon steel (C1022A), intambo edibeneyo	Amandla aphezulu okwenza intambo; iintambo eziqengqelekayo zonyusa ukudinwa
Indawo yokudweba	Ingcebiso yoqheliso oluqinileyo, HRC 55–60	Ubhobhoza ngentsimbi ukuya kuthi ga kwi-6.0 mm ubukhulu kumsebenzi omnye
Ukwaleka	Ruspert i-ceramic-organic composite coating	Ubomi obude bokuchasana nomhlwa kunye nomqobo wokunqanda ukubola

Imigangatho yemveliso: GB/T 15856.4 / DIN 7504K (i-hex flange intloko ye-self-drilling screws); intambo nge GB/T 5280 / ISO 1478.

3.I-Ruspert Coating: iTekhnoloji yeCeramic-Organic Anti-Corrosion Technology

Ukukhuselwa komqobo- ii-flakes zetsimbi ezifana nepleyiti zidala indlela eyingozi ethintela amanzi, ioksijini, kunye ne-chloride ion ukufikelela kwi-substrate yentsimbi.
Ukukhuselwa kwedini- i-zinc component i-corrodes ngokukhethekileyo, inikezela ukhuseleko lwe-galvanic (cathodic) nokuba i-coating ihlanjululwe kwindawo ye-drill okanye i-thread crests.
Akukho mngcipheko we-hydrogen embrittlement- ngokungafaniyo ne-electro-plating, i-Ruspert yinkqubo ye-non-electrolytic dip-spin, ngoko akukho ntlawulo ye-hydrogen ye-screw body eqinile.
Uzinzo lweDimensional- i-coating yakha kuphela i-6-12 µm yobukhulu, ngoko ke iintambo zigcina igeyiji yazo kwaye zihlangane kakuhle ngaphandle kokuphinda ucofe.

Xa kuthelekiswa nokugqitywa kwe-screw eqhelekileyo, u-Ruspert uhlala kwindawo ephezulu yokhuseleko lomhlwa olungabizi kakhulu:

Gqiba	Isitshizi esiqhelekileyo seTyuwa ukuya kwiRust eBomvu (ISO 9227 / ASTM B117)	Iindleko ezizalanayo	Amanqaku
I-zinc emhlophe / eluhlaza okwesibhakabhaka	24–72 h	Phantsi	Ukusetyenziswa kwangaphakathi okanye okomileyo ngaphakathi kuphela
Ukufakwa kwe-zinc etyheli	72–120 h	Phantsi–Phakathi	Ukubonakaliswa okukhanyayo kwangaphandle
Ukugalela oomatshini	240–400 h	Phakathi	Ilungele izibophelelo zonxweme
I-Dacromet / i-zinc flake (esisiseko)	480–720 h	Phakathi–Phakamileyo	Iinketho zasimahla zeChrome ziyafumaneka
Ruspert 500	I-500 h, akukho mhlwa obomvu	Phakathi–Phakamileyo	Ibakala eliqhelekileyo lokufulela ngaphandle

4. Ukuqukumbela

Kuba ngaphandle screw fastening apho umhlwa lutshaba, i I-Ruspert composite washer yokomba isikrufu inika indibaniselwano enqabileyo: i-drill-point convenience, i-EPDM yokutywinwa, kunye ne-ceramic-organic anti-corrosion technology ilinganiswe kwiiyure ze-1,000 + zokunyamezela isitshizi setyuwa. Yandisa ubomi benkonzo yejoyinti edibeneyo ukuze ihambelane - kwaye ihlala iphuma ngaphandle - inkqubo yokuphahla okanye i-cladding ngokwayo, ukusika imijikelezo yokugcina kunye neendleko ezipheleleyo zobunini.

Ngolwazi lweenkcukacha zobugcisa, iingxelo zovavanyo lwesitshizi setyuwa, kunye neenkcukacha zesijivu esiziqhelileyo, qhagamshelana neqela lethu lokuthumela ngaphandle.

Ngaphambili. Okulandelayo.
