RUSPERT Self-Tapping Screws-A Tekinoroji Yekutarisa yeAnti-Corrosion Self-Tapping Fasteners.
2026-07-13
Self-tapping screws ane RUSPERT pamusoro pekurapa anosanganisa kurerukira kweshinda-kuumba kuisirwa neye premium matatu-layer anti-corrosion coating system. Iri gwaro rinopa muchidimbu kupfupikiswa kwe-self-tapping screw types uye iyo RUPERT yekupotera tekinoroji iyo inopa 1,000+ maawa ekudzivirira munyu wekupfapfaidza pasina njodzi yehydrogen embrittlement.
Chikamu 1 - Self-Tapping Screw Types
Self-tapping screws inoumba yavo yemukati tambo panguva yekuisa, ichibvisa kudiwa kwe pre-tapping mashandiro. Zvikamu zvina zvekutanga zvinoshandisa zvinhu zvakasiyana uye zvinoremerwa zvinodiwa, chimwe nechimwe chinosiyaniswa neshinda-yekugadzira michina uye poindi geometry.
Type Classification
| Type | Standard | Tsanangudzo | Best For |
| Thread-Kugadzira | Nyora A / AB / B | Inobvisa zvinhu kugadzira shinda dzemukati. Inoda gomba rekutyaira. Hapana kubvisa zvinhu. | Plastiki, simbi dzakapfava, huni |
| Thread-Kucheka | Rudzi F / BF / 25 | Zvimiro zvekucheka nyere dzinobvisa zvinhu panguva yekuisa, kugadzira tambo dzakachena. | Simbi dzakaoma, brittle zvinhu |
| Thread-Rolling | Nyora TR / LO-DRIVE | Cold-forms threads pasina kucheka. Haabudisi machipisi. Kunyanya kusunungura kupikisa. | Sheet simbi, maburi akawedzera |
| Kuzviboorera | DIN 7504 / TEK | Integral drill-bit point drills uye matepi mukushanda kumwe. Hapana gomba rekutyaira rinodiwa. | Thin-gauge simbi, HVAC, denga |
Common Standards & Materials
Maitiro: DIN 7976, DIN 7504, ISO 15480, GB/T 43655
Zvekushandisa: Carbon simbi (C1018-C1045), alloy simbi, Stainless simbi
Mhando dzemusoro: Pan musoro, countersunk (musoro wakafuratira), hex musoro, hex washer musoro, musoro wakatenderera
Chikamu 2 - RUPERT Coating Technology
RUPERT (路 锈宝) ndeyepamusoro-giredhi, inoshamwaridzana nemamiriro ekunze maitiro ekurapa maitiro anowanzo shandiswa kune kabhoni uye alloy simbi fasteners. Inoshandisa matatu-layer coating structure inosanganisa chibayiro galvanic dziviriro nedura receramic barriers, kuwana 1,000-1,500 maawa ekusarerekera munyu kupfapfaidza kuramba - zvakanyanya kudarika zvakajairwa zinc plating.
Matatu-Layer Structure
| Layer | Composition | Function | Dziviriro Mechanism |
| Layer 1 - Metallic Zinc | Electrodeposited zinc | Kuzvipira cathodic kudzivirira kwesimbi substrate | Galvanic - zinc corrodes zviri nani |
| Layer 2 - Kemikari Shanduko | Chromate / passivation firimu | Inosimudzira kunamatira pakati pe zinc uye ceramic layers | Chemical bonding + kuzvirapa |
| Layer 3 - Yakabikwa Ceramic Topcoat | Zinc-aluminium flake + resin | Chipingamupinyi chinopesana nehunyoro, munyu, oxygen uye makemikari | Physical chipingamupinyi + non-conductive |
Iwo matatu akaturikidzana akasunganidzwa pamwechete kuburikidza nekuita kwemakemikari, achigadzira firimu rakaoma, rakaomarara rinonamira zvakasimba kune substrate yesimbi. Uku kusanganisa kwakasarudzika kwematanho kunopa zvese zvinoshanda (chibairo) uye passive (chipingamupinyi) dziviriro yekuora.
Hunhu Hunokosha
Superior corrosion resistance: 1,000–1,500 maawa asina kwayakarerekera munyu pfapfaidzo (NSS) paISO 9227, zvichienzaniswa nemaawa makumi mapfumbamwe nematanhatu–240 ekuiswa zinc plating.
Hapana hydrogen embrittlement: Kudzika-tembiricha yekurapa maitiro kunodzivirira kunyura kwehydrogen, zvichiita kuti RUSPERT ive yakachengeteka kune yakakwirira-simba fasteners (Giredhi 8.8-12.9) uko electroplating inounza njodzi yekukanganisa.
Kuoma kwepamusoro pepamusoro: RUSPERT kupfekedza kwakaoma kupfuura Dacromet, inopa kupfeka kwepamusoro uye kukwenya kuramba panguva yekuisa uye sevhisi.
Inodzivirira bimetallic corrosion: Iyo isiri-conductive ceramic topcoat inotsaura zinc layer kubva pakubata nesimbi dzakasiyana (semuenzaniso, aruminiyamu, galvanized simbi), kubvisa galvanic corrosion yezvivakwa zviri pedyo.
Zvinoenderana nemamiriro ekunze: Cr⁶⁺-yemahara, RoHS uye REACH zvinoenderana. Hapana chepfu hexavalent chromium inoshandiswa mukuita.
Coating Kuenzanisa
| Property | RUPERT | Zinc Plating | Dacromet |
| Kupfapfaidza munyu (maawa) | 1,000 - 1,500 | 96 – 240 | 500 - 1,200 |
| Hydrogen Embrittlement | Hapana | Njodzi (Grade 10.9+) | Hapana |
| Pamusoro Kuoma | High | Pakati | Pakati |
| Cr⁶⁺ Yemahara | Hongu | Inosiyana | Hongu |
| Chitarisiko | Rima grey / dema | Bhuruu-chena / yakajeka | Sirivha-grey |
| Bimetallic Corrosion | Kudzivirirwa | Zvinogoneka | Yakaderedzwa |
| Cost Level | Pakati-Pamusoro | Low | Pakati |
Kupfapfaidza munyu pa ISO 9227 NSS. Bimetallic corrosion inoreva galvanic kurwisa kana RUSPERT-yakavharwa fasteners inobata aruminiyamu kana galvanized simbi pamusoro.
Applications
Coastal & Marine: Denga, kuvharisa, uye zvimiro zvinongedzo munzvimbo dzakaremerwa nemunyu.
Kunze zvimiro: Fencing, decking, pergolas, uye ezvivakwa facades akaoneswa nemamiriro ekunze.
ACQ-yakagadziriswa matanda: RUPERT inoshingirira kuparara kwemhangura-based preservatives mumatanda emazuva ano anodzvanywa.
Motokari: Underbody fasteners, chassis yekubatanidza, uye exhaust system zvakabatanidzwa.
Simba reMhepo & kugadzirwa kwesimbi: Hupenyu hurefu hwemagadzirirwo ekubatanidza anoda kuchengetedza-isina corrosion dziviriro.
Summary
RUSPERT-yakavharwa self-tapping screws inopa inomanikidza musanganiswa wekumisikidza kuve nyore uye yenguva refu yekudzivirira ngura. Iyo yekuzvigadzika dhizaini inobvisa pre-tapping, nepo matatu-layer RUSPERT system inoburitsa 1,000+ maawa emunyu wekupfapfaidza kuramba pasina hydrogen embrittlement - zvichiita kuti zvisungo izvi zvive zvakanaka kune kunze, kumahombekombe, uye makemikari nharaunda uko kwakajairika zinc plating yaizotadza nguva isati yakwana.
