Ruspert (路锈宝) Coated Self-Drilling Screws-Ib qho Kev Taw Qhia rau Kev Ua Tau Zoo Tshaj Plaws-Tail Fasteners 

1. Taw qhia

Self-drilling screws, paub nyob rau hauv Suav li "钻尾丝" (drill-tail screws) los yog Tek screws, yog tshwj xeeb fasteners uas xyaum lawv tus kheej pilot qhov thiab tsim mating threads nyob rau hauv ib qho kev lag luam. Thaum kho nrog Ruspert (路锈宝) txheej - ntau txheej, siab-corrosion-resistance saum npoo kev kho mob - lawv dhau los ua ib qho kev txhim khu kev qha thiab raug nqi zoo rau kev siv hlau, vov tsev, thiab kev lag luam.

Ruspert-coated self-drilling screws muab cov neeg kho tshuab lub zog thiab drilling efficiency ntawm cov cua kub kho carbon steel nrog zoo heev los tiv thaiv corrosion kev ua tau zoo uas feem ntau tshaj cov txheej txheem zinc plating thiab txawm tias qee cov qib stainless hauv kev ntsuas nrawm. Lawv yog cov nyiam rau xim hlau pobzeb (彩钢瓦) kev teeb tsa, lub teeb-gauge steel framing, hlau vov tsev, phab ntsa cladding, thiab sab nraum zoov kev sib txuas.

2. Ruspert Txheej yog dab tsi?

Ruspert (RUSPERT / 路锈宝) yog cov txheej txheem ntau txheej txheej txheej txheej txheem tsim kom muaj kev tiv thaiv corrosion siab. Tsis zoo li ib txheej zinc plating, nws muaj ob peb txheej txheej tshwj xeeb:

• Ib txheej hlau zinc lossis zinc-alloy puag txheej muab kev tiv thaiv cathodic sacrificial;
• Intermediate conversion/passivation txheej uas txhim khu adhesion thiab kuj;
• Ib lossis ntau cov organic topcoat cov khaubncaws sab nraud povtseg uas khi rau saum npoo thiab txhim kho tshuaj tiv thaiv (muaj nyob rau hauv ntau yam xim).

Corrosion Performance

Kev soj ntsuam ywj pheej (feem ntau los ntawm SGS) qhia tau hais tias qhov zoo ntawm Ruspert-coated carbon steel screws tuaj yeem ua tiav qhov nruab nrab ntsev tsuag tshuaj tiv thaiv ntawm 1,000 teev lossis ntau dua (qib qib siab txog li 1,500 teev) yam tsis muaj xeb tseem ceeb, ntxiv rau kev ua tau zoo hauv kev sim cyclic acid-los nag (15-25 cycles). Hauv kev sib piv, cov pa roj carbon steel + Ruspert feem ntau ua tau zoo tshaj 410 stainless hlau hauv kev ntsuas ntsev-txhaj tshuaj thaum tseem pheej yig dua li qib austenitic xws li 304 lossis 316.

3. Cov yam ntxwv tseem ceeb

Self-Drilling Peev Xwm & Lub Zog

Qhov tshwj xeeb engineered xyaum taw tes (feem ntau Dual-Edge los yog multi-flute) tso cai rau lub fastener nkag mus rau steel ntawv yam tsis muaj pre-drilling. Cov khoom lag luam zoo tuaj yeem ntseeg tau los ntawm 4-6 hli ntawm cov hlau hauv ib qho kev ua haujlwm, txiav lub sijhawm ua haujlwm tau zoo. Feem ntau cov ntsia hlau yog tsim los ntawm cov cua kub-kho cov pa roj carbon steel (feem ntau C1022), xa cov tensile siab, shear, thiab rub tawm lub zog.

Xov & Lub taub hau xaiv

Cov kev teeb tsa muaj xws li cov xov xov tag nrho rau kev siv dav dav thiab ob txoj hlua (dual-xov) tsim uas muaj kev tiv thaiv kev rub tawm ntau dua - tshwj xeeb tshaj yog muaj txiaj ntsig zoo rau kev ruaj ntseg cov ntawv vov tsev ntawm crest. Lub taub hau feem ntau yog lub taub hau hex washer (tsav nrog 8 hli / 5/16 "socket), feem ntau muab nrog cov khoom sib txuas EPDM rau huab cua nruj sealing. Countersunk thiab lwm yam qauv kuj muaj.

Hom Specifications

Kev lag luam loj loj muaj xws li:

Lus Cim: Qhov tseeb drilling peev xwm nyob ntawm steel hardness, taw tes tsim, thiab torque. Nco ntsoov xa mus rau cov chaw tsim khoom cov ntaub ntawv rau cov ntawv thov tseem ceeb.

4. Cov ntawv thov tseem ceeb

Ruspert-coated self-drilling screws yog dav siv nyob rau txhua qhov chaw ceev, txhim khu kev qha fastening ntawm cov ntawv hlau lossis cov tswv cuab lub teeb, tshwj xeeb tshaj yog qhov tseem ceeb ntawm kev tiv thaiv corrosion.

Hlau Roofing & Xim Steel Pobzeb Systems

Feem ntau siv. Screws kho corrugated lossis trapezoidal xim-coated steel nplooj ntawv (彩钢瓦) rau steel purlins. Hex-washer-head versions nrog sib koom ua ke EPDM ntxhua khaub ncaws muab ob qho tib si fastening thiab huab cua sealing. Muab ob npaug rau xov tsim txhim kho cua-uplift tsis kam ntawm daim ntawv crest.

Phab ntsa Cladding, Sandwich Panels & Steel Framing

Siv rau ntsug / kab rov tav hlau phab ntsa cladding, insulated sandwich panels, thiab lub teeb-gauge steel framing (studs, lem, lwm tus neeg). Cov txheej txheej durability yog tshwj xeeb tshaj yog muaj nuj nqis nyob rau hauv ntug dej hiav txwv, kev lag luam, los yog high-humidity ib puag ncig. Kuj tseem siv rau hauv photovoltaic mounting systems, HVAC kev txhawb nqa, cov tsev ua liaj ua teb, thiab kev tsim hlau dav dav.

5. Qhov zoo tshaj lwm txoj kev fasteners

Piv nrog cov zinc-plated zoo tib yam screws, ntshiab stainless-steel self-drilling screws, los yog cov tsoos bolted kev twb kev txuas, Ruspert-coated cov khoom muaj ib tug sib npaug ntawm cov txiaj ntsig:

6. Cov txheej txheem xaiv thiab siv

Xaiv Qhov Loj & Point Hom

Xaiv txoj kab uas hla raws li cov khoom thickness thiab load yuav tsum. Cov ntsia hlau ntev dua yog xav tau thaum fastening los ntawm rwb thaiv tsev los yog ntau txheej. Txheem # 2 / # 3 cov ntsiab lus haum cov ntawv nyias nyias; thicker structural steel (ze los yog siab dua 6 mm) yuav tsum tau tshwj xeeb cov ntsiab lus ntev. Nco ntsoov xyuas cov chaw tsim khoom lub peev xwm drilling.

Installation Cov kev coj ua zoo tshaj plaws

1.Siv lub qhov (socket) zoo sib nqus hex thiab tus tsav tsheb sib txawv-ceev nrog adjustable torque clutch.

2.Thov khov kho, siab nruab nrab; zam dhau kev quab yuam uas ua rau taw tes wandering lossis lub taub hau stripping.

3.Nrog cov tshuab ntxhua khaub ncaws, tsis txhob tsav tsheb thaum lub tshuab ntxhua khaub ncaws raug compressed (hlau ntxhua khaub ncaws pib flatten me ntsis).

4.Hauv cov txheej txheem tseem ceeb lossis kev siv cua tshuab, ua raws li qhov project engineer lub sijhawm teem sijhawm thiab qhov sib nrug.

Environmental Considerations

Thaum Ruspert coatings muaj kev tiv thaiv zoo heev, ib puag ncig hnyav heev (nruam seawater immersion, high acidic industrial atmospheres, los yog muaj zog galvanic khub niam txiv) tseem yuav xav tau stainless lossis bi-metallic fasteners. Rau feem ntau ntawm cov huab cua sab nraum zoov - suav nrog cov chaw ntug dej hiav txwv thiab chaw lag luam - zoo Ruspert-coated screws muab lub neej ntev kev pab cuam thaum raug teeb tsa.

7. Cov lus xaus

Ruspert (路锈宝) coated self-drilling screws ntse txuas qhov sib txawv ntawm cov pa roj carbon-steel fasteners thiab kim kim stainless-steel lwm txoj. Kev sib xyaw ua ke ntawm cov cua kub-kho carbon-steel core, ib qho kev ua haujlwm zoo ntawm tus kheej, thiab ntau txheej txheej ua haujlwm siab tiv thaiv corrosion, lawv xa cov installation ceev, txhim khu kev qha mechanical kev ua tau zoo, thiab ua haujlwm zoo rau kev siv hlau thiab kev siv vov tsev.

Txawm hais tias kho cov xim hlau vuas, sib sau ua ke lub teeb-gauge steel qauv, lossis kev ruaj ntseg cladding panels, cov ntsia hlau no tseem yog qhov kev xaiv zoo tshaj plaws rau cov neeg cog lus thiab cov kws tsim khoom nrhiav kev tsim khoom thiab kev ntseeg tau ntev. Thaum xaiv cov khoom lag luam, qhov chaw los ntawm cov tuam txhab muaj npe nrov uas muab cov ntaub ntawv pov thawj ntsev-txhaj tshuaj thiab cov ntaub ntawv ntsuas kev ntsuas kom ntseeg tau tias cov qib kev ua tau zoo tau ua tiav tas li.
