RUPERT Self-Tapping Screws-Tlhahlobo ea Tekheniki ea Li-Fasteners tse Anti-Corrosion
2026-07-13
Li-screws tse itšebetsang tse nang le kalafo ea bokaholimo ba RUPERT li kopanya boiketlo ba ho kenya likhoele ka mokhoa oa ho roala oa mekato e meraro o thibelang kutu. Tokomane ena e fana ka kakaretso e khuts'oane ea mefuta ea "screw" ea "self-tapping" le theknoloji ea ho roala ea RUPERT e fanang ka ts'ireletso ea lihora tse 1,000+ tsa ts'ireletso ea letsoai ntle le kotsi ea hydrogen embrittlement.
Karolo ea 1 - Mefuta ea Self-Tapping Screw
Li-screws tse itšebetsang li iketsetsa likhoele tsa tsona tsa ka hare nakong ea ho kenya, ho felisa tlhokahalo ea ts'ebetso ea pele ho ho tlanya. Likarolo tse 'ne tsa mantlha li sebeletsa lisebelisoa tse fapaneng le litlhoko tsa mojaro, e' ngoe le e 'ngoe e khetholloa ka mochini oa eona oa ho etsa likhoele le geometry ea lintlha.
Mofuta oa Sehlopha
| Mofuta | Standard | Tlhaloso | Molemo ka ho fetisisa Bakeng sa |
| Ho Etsa Likhoele | Mofuta oa A / AB / B | E tlosa lintho ho etsa likhoele tse ka hare. E hloka lesoba la sefofane. Ha ho tlosoe lintho tse bonahalang. | Plastiki, litšepe tse bonolo, lehong |

Karolo ea 2 - RUPERT Coating Technology
RUPERT (路 锈宝) ke mokhoa oa boemo bo holimo, o nang le botsoalle ba tikoloho, o atisang ho sebelisoa ho li-fasteners tsa carbon le alloy steel. E sebelisa sebopeho sa ho roala ka mekhahlelo e meraro se kopanyang tšireletso ea galvanic ea sehlabelo le mokoallo o tšoarellang oa ceramic, ho finyella lihora tse 1,000-1,500 tsa ho hanyetsa ha letsoai ho sa nke lehlakore - ho feta ho rarahana ha zinki ho tloaelehileng.
Sebopeho sa Mehato e meraro
| Lera | Sebopeho | Mosebetsi | Mokhoa oa Tšireletso |
| Lera 1 - Metallic Zinc | Electrodeposited zinki | Tšireletso ea cathodic ea sehlabelo bakeng sa substrate ea tšepe | Galvanic - zinki corrodes preferentially |
| Lera 2 - Phetoho ea Lik'hemik'hale | Filimi ea Chromate / passivation | E khothalletsa ho khomarela pakeng tsa zinki le lira tsa ceramic | Ho kopanya lik'hemik'hale + ho ipholisa |
| Lera 3 - Topcoat ea Ceramic e Bakiloeng | Zinc-aluminium flake + resin | Tšitiso khahlanong le mongobo, letsoai, oksijene le lik'hemik'hale | Tšitiso ea 'mele + e sa tsamaisaneng |
Likarolo tse tharo li kopantsoe hammoho ka ho kopana ha lik'hemik'hale, ho etsa filimi e teteaneng, e thata e khomarelang ka thata ho substrate ea tšepe. Motsoako ona o ikhethang oa mekhahlelo o fana ka ts'ireletso ea ts'ireletso e sebetsang (ea sehlabelo) le e sa sebetseng (thibelo).
Melemo ea Bohlokoa
Khanyetso e phahameng ea corrosion: Lihora tse 1,000–1,500 tsa setlolo sa letsoai se sa nke lehlakore (NSS) ho latela ISO 9227, ha ho bapisoa le lihora tse 96–240 bakeng sa ho roala zinki ho tloaelehileng.
Ha ho na hydrogen embrittlement: Mokhoa oa ho folisa mocheso o tlase o qoba ho kenngoa ha haedrojene, ho etsa hore RUPERT e bolokehe bakeng sa li-fasteners tse matla haholo (Kereiti ea 8.8-12.9) moo electroplating e bakang kotsi ea embrittlement.
Ho thatafala holimo holimo: Ho roala ha RUPERT ho thata ho feta Dacromet, ho fana ka moaparo o phahameng le khanyetso nakong ea ho kenya le tšebeletso.
E thibela ho bola ha bimetallic: The non-conductive ceramic topcoat e arola lesela la zinki ho tloha ho kopana le lirafshoa tse sa tšoaneng (mohlala, aluminium, tšepe ea galvanized), ho felisa galvanic corrosion ea mehaho e haufi.
E lumellana le tikoloho: Ha e na Cr⁶⁺, RoHS le REACH lia lumellana. Ha ho na chefo e chefo ea chromium e sebelisitsoeng ts'ebetsong.
