Kakaretso ea Phethahatso

The Ruspert composite washer drilling screw ke sekurufu sa pele sa ho ithuisa se entsoeng bakeng sa ho tiisa tšepe ho isa ho tšepe le tšepe ho ea ho mapolanka libakeng tse mabifi tsa kantle. Ka ho kopanya 'mele oa sekoti se thata-thata, sebaka sa ho phunya se etsang mohato o le mong oa ho cheka le ho tlanya, le bonded EPDM composite sealing washer, lelapa lena la screw le hahiloe bakeng sa ts'ebetso ea nako e telele e khahlanong le mafome.

Sireletsoa ke Ruspert ceramic-organic anti-rust coating, li-screws li fana ka ho Lihora tse 1,000+ tsa ho hanyetsa ho fafatsa letsoai ntle le mafome a mafubelu - tse fetang hōle li-screw tse tloaelehileng tsa electro-plated. Sengoliloeng sena se hlalosa sebopeho sa screw, thekenoloji ea ts'ireletso ea kutu ka mor'a ho roala, lintlha tse netefalitsoeng tsa tlhahlobo ea anti-rust, le tataiso e sebetsang ea khetho le ho kenya bakeng sa merero ea ho rulela, ea ho roala le ho holisa letsatsi.

1. Screw ea ho Drilling ea Composite Washer ke Eng?

A Sekurufu sa ho cheka washer e kopaneng (eo hape e bitsoang "self-drilling screw with bonded sealing washer" ke sekontiri se khoele se etsang liopereishene tse tharo ketso e le 'ngoe ea ho khanna: ho cheka, ho etsa likhoele, le ho tiisa. Ho fapana le li-screws tse tloaelehileng tsa ho itlama, sebaka se kopantsoeng sa ho phunya se tlosa tlhokahalo ea ho cheka pele.

Sehlapa sa rabara sa EPDM se senyehileng - se tlamelletsoeng ho sekoahelo sa tšepe se entsoeng ka masenke - se hatella holim'a bokaholimo ho etsa tiiso e tiisang boemo ba leholimo, e sa lutleng.

Ka mantsoe a hlakileng: screw e le 'ngoe e nkela sebaka sa ho phunya, screw ea ho tlanya, le washer e arohaneng ea rabara - 'me e boloka mafome le metsi a pula lilemo tse ngata.

Lelapa la sehlahisoa hangata le akaretsa:

Hex washer Head (HWH) ho cheka likurufu- maemo a indasteri ea marulelo
Countersunk (flat head) li-screws tsa ho phunya- bakeng sa lits'ebetso tsa flush-finish
Li-screws tsa ho cheka li-pan / konopo hloohong- bakeng sa lakane tšepe le ductwork

2.Anatomy of the Screw

Karolo	Thepa & Moralo	Mosebetsi
Hlooho	Hlooho ea hex washer e nang le serrated flange (kapa countersunk)	Phetiso ea torque e phahameng; flange e aba moroalo oa clamping
Washer e kopantsoeng	Rabara ea EPDM e hlasetsoe ka har'a sekoahelo sa zinki / 304 tšepe e sa hloekang	Tiiso e thibelang boemo ba leholimo; e monya ho thothomela; Litšebeletso tsa UV le ozone, −40 °C ho ea +120 °C
Shank & khoele	Case-hardified carbon steel (C1022A), khoele e rokotsoeng	Matla a phahameng a ho etsa khoele; likhoele tse phuthoang li eketsa ho hanyetsa mokhathala
Sebaka sa ho phunya	Keletso e thata ea ho cheka, HRC 55–60	E cheka ka tšepe ho fihlela ho 6.0 mm botenya ts'ebetsong e le 'ngoe
Ho roala	Ruspert ho roala ka ceramic-organic composite	Thibelo ea nako e telele e thibelang mafome le thibelo ea ho senya

Litekanyetso tsa sehlahisoa: GB/T 15856.4 / DIN 7504K (hex flange head self-dolling screws); khoele ka GB/T 5280 / ISO 1478.

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

Tšireletso ea mokoallo- li-flakes tsa tšepe tse kang poleiti li etsa tsela e sothehileng e thibelang metsi, oksijene le li-ion tsa chloride ho fihla karolong e ka tlaase ea tšepe.
Tšireletso ea sehlabelo- karolo ea zinki e senya ka ho khetheha, e fana ka tšireletso ea galvanic (cathodic) esita le haeba seaparo se phunyeletsoa sebakeng sa ho phunya kapa likhoele tsa khoele.
Ha ho kotsi ea hydrogen embrittlement- ho fapana le electro-plating, Ruspert ke mokhoa o se nang electrolytic dip-spin, kahoo ha ho na ho tjhaja hydrogen ea 'mele oa screw o thata.
Botsitso ba dimensional- ho roala ho haha limilimithara tse 6-12 feela tsa botenya, kahoo likhoele li boloka sekala sa tsona 'me li kopane hantle ntle le ho tlanya hape.

Ha a bapisoa le li-screw tse tloaelehileng, Ruspert o lula sebakeng se kaholimo sa tšireletso ea kutu e baballang chelete e ngata:

Qetella	Sefafatsi se Tloaelehileng sa Letsoai ho Rust e Khubelu (ISO 9227 / ASTM B117)	Litšenyehelo tse Batlang	Lintlha
Ho roala zinki tse tšoeu / tse putsoa	24–72 h	Tlase	Tšebeliso ea ka hare kapa ka hare e omme feela
Ho roala zinki e mosehla	72–120 h	Tlase–Mahareng	Khanya ea kantle
Mechanical galvanizing	240–400 h	Mahareng	E loketse li-fasteners tsa lebopong
Dacromet / zinc flake (ea motheo)	480–720 h	Mahareng–Hodimo	Likhetho tsa mahala tsa Chrome lia fumaneha
Ruspert 500	500 h, ha ho na mafome a khubelu	Mahareng–Hodimo	Sekolo se tloaelehileng sa marulelo a ka ntle

4. Qetello

Bakeng sa ka ntle screw fastening moo mafome ke sera, the Ruspert composite washer drilling screw e fana ka motsoako o sa tloaelehang: bonolo ba ho cheka, ho tiisa EPDM, le theknoloji ea ceramic-organic anti-corrosion e lekantsoeng lihora tse 1,000+ tsa mamello ea ho fafatsa letsoai. E eketsa bophelo ba ts'ebeletso ea lenonyeletso le tlamahantsoeng hore le ts'oane - 'me hangata le fetele pele - sistimi ea ho rulela kapa ea ho koala ka boeona, potoloho ea tlhokomelo le litšenyehelo tse felletseng tsa beng.

Bakeng sa lipampitšana tsa tekheniki, litlaleho tsa tlhahlobo ea sefafatsi sa letsoai, le lintlha tse ikhethileng tsa screw, ikopanye le sehlopha sa rona sa thomelontle.

E fetileng E latelang.
