| The Ruspert composite wanki hakowa dunƙule babban dunƙule mai haƙowa kai ne wanda aka ƙera don ƙarfe-zuwa-karfe da ɗaure ƙarfe-zuwa katako a cikin yanayin waje mai tsananin zafi. Ta hanyar haɗa jikin dunƙule karfe mai kauri, wurin rawar soja wanda ke yin hakowa mataki ɗaya da bugun, da bonded EPDM composite sealing washer, Wannan dunƙule iyali an gina shi don dogon rai anti-tsatsa yi. Mai kare shi Ruspert yumbu-kwayoyin anti-tsatsa shafi, da sukurori isar har zuwa Sa'o'i 1,000+ na juriya na feshin gishiri ba tare da jan tsatsa ba - nisa ƙetare na al'ada electro-plated sukurori. Wannan labarin ya bayyana tsarin dunƙule, fasahar kariyar lalata da ke bayan rufin, ingantattun bayanan gwajin tsatsa, da zaɓi mai amfani da jagorar shigarwa don yin rufi, sutura, da ayyukan hawan hasken rana. |
1. Menene Haɗin Hakowa Mai Haɗin Washer?
A hadaddiyar wanki hakowa dunƙule (kuma ana kiransa screw-drilling screw with bonded sealing washer) wani zaren zare ne wanda ke yin ayyuka uku a cikin aikin tuƙi ɗaya: hakowa, zare-forming, da kuma rufewa. Ba kamar skru na yau da kullun ba, haɗaɗɗen wurin rawar soja yana kawar da buƙatar tuƙi.
Mai wankin roba na EPDM mai ɓarna - an haɗa shi da hular goyan bayan ƙarfe mai galvanized - yana matsawa saman panel ɗin don samar da hatimin da ba zai yuwu ba.
| A bayyane yake: dunƙule ɗaya yana maye gurbin ɗigon rawar jiki, screw ɗin tapping, da na'urar wanke roba daban - kuma yana kiyaye tsatsa da ruwan sama na shekaru. |
Iyalin samfurin yawanci sun haɗa da:
- Hex washer head (HWH) hako sukurori- daidaitattun masana'antar rufi
- Countersunk (lebur kai) hako sukurori- don aikace-aikacen gamawa
- Pan / button shugaban hako sukurori- domin takardar karfe da ductwork
2. Anatomy of Screw
| Bangaren | Material & Zane | Aiki |
| Shugaban | Hex mai wanki shugaban tare da serrated flange (ko countersunk) | Babban karfin watsawa; flange yana rarraba nauyin matsawa |
| Kunshin wanki | EPDM roba vulcanized zuwa zinc-plated / 304 bakin karfe hula | Hatimin yanayi; yana shayar da girgiza; UV da ozone resistant, -40 °C zuwa +120 °C sabis |
| Shank & zaren | Case-hardened carbon karfe (C1022A), birgima zaren | Babban ƙarfin samar da zaren; birgima zaren ƙara gajiya juriya |
| Wurin hakowa | Tushen rawar soja, HRC 55-60 | Haɗa ta ƙarfe har zuwa kauri 6.0 mm a cikin aiki ɗaya |
| Tufafi | Ruspert yumbu-kwayoyin halitta hade shafi | Tsatsa na tsawon rai da shingen lalata |
Matsayin samfur: GB/T 15856.4 / DIN 7504K (hex flange kai sukulan hakowa); Zare da GB/T 5280 / ISO 1478.
3.Ruspert Coating: Ceramic-Organic Anti-Corrosion Technology
- Kariyar shinge- Filashin ƙarfe kamar farantin karfe yana haifar da turɓayar hanya wacce ke toshe ruwa, iskar oxygen, da ions chloride isa ga ma'aunin ƙarfe.
- Kariyar hadaya- Bangaren zinc yana lalata da kyau, yana ba da kariya ga galvanic (cathodic) ko da an zazzage murfin a wurin rawar soja ko zaren zaren.
- Babu haɗarin haɓakar hydrogen- sabanin electro-plating, Ruspert tsari ne wanda ba na lantarki ba ne, don haka babu cajin hydrogen na jikin dunƙule mai tauri.
- Kwanciyar kwanciyar hankali- rufin yana gina kauri kawai 6-12 µm, don haka zaren suna kiyaye ma'aunin su kuma suna taruwa lafiya ba tare da sake bugawa ba.
Idan aka kwatanta da gamawar dunƙule gama gari, Ruspert yana zaune a saman matakin kariyar lalata mai inganci:
| Gama | Gishiri na yau da kullun zuwa Jan Tsatsa (ISO 9227 / ASTM B117) | Farashin Dangi | Bayanan kula |
| White / blue zinc plating | 24-72 h | Ƙananan | Amfani na ciki ko bushewa kawai |
| Yellow zinc plating | 72-120 h | Ƙananan-Matsakaici | Haske a waje |
| Injiniya galvanizing | 240-400 h | Matsakaici | Yana da kyau ga masu haɗin bakin teku |
| Dacromet / zinc flake (na asali) | 480-720 h | Matsakaici-Maɗaukaki | Akwai zaɓuɓɓuka marasa Chrome |
| Ruspert 500 | 500h, babu jan tsatsa | Matsakaici-Maɗaukaki | Daidaitaccen darajar rufin waje |
4. Kammalawa
Domin waje dunƙule fastening inda tsatsa ne abokan gaba, da Ruspert composite wanki hakowa dunƙule yana ba da haɗin haɗin da ba kasafai ba: saukakawa-maki, EPDM sealing, da yumbu-kwayoyin rigakafin lalata da aka ƙididdige su zuwa sa'o'i 1,000+ na juriyar feshin gishiri. Yana tsawaita rayuwar sabis ɗin haɗin gwiwa don daidaitawa - kuma sau da yawa ya wuce - rufin rufin ko tsarin sutura da kanta, yankan zagayowar kulawa da jimillar farashin mallaka.
Don takaddun bayanan fasaha, rahoton gwajin feshin gishiri, da ƙayyadaddun ƙira, tuntuɓi ƙungiyar mu na fitarwa.
