Dacromet Yashizwemo Flange Bolts 

2. Gusobanukirwa Ikoranabuhanga rya Dacromet

Dacromet ni amazi ashingiye kumazi, sisitemu ya elegitoroniki ya zinc-aluminium ya flake itunganijwe neza yakozwe kubifata, harimo imbaraga zikomeye za flange. Bitandukanye nuburyo gakondo bwo gukwirakwiza amashanyarazi bubika ion ibyuma binyuze mumashanyarazi, inzira ya Dacromet ikoresha uburyo bwitondewe burimo flake ya zinc, flake ya aluminium, hamwe nudusimba twa organic organique hejuru ya bolt. Nyuma yo kuyikoresha ukoresheje uburyo bwa dip-spin cyangwa spray, ibishishwa bitwikiriye bikiza ubushyuhe bwo hejuru (mubisanzwe hafi 300 ° C), bigacumura flake muri firime ihujwe cyane, igizwe na firime nyinshi.

Ipfunyika ya Dacromet iroroshye cyane - mubisanzwe hagati ya micrometero 6 na 12 - nyamara itanga imbaraga zo kurwanya ruswa. Zinc na aluminiyumu zirenze urugero zikora inzitizi ya labyrintine itinda cyane kwinjira mubushuhe, ogisijeni, hamwe na ion zibora. Icyarimwe, zinc itanga ibitambo (cathodic) kurinda ibyuma byubatswe munsi ya bolt, mugihe ibice bya aluminium na chromate byongera passivation hamwe nigihe kirekire cyo kurwanya ingese. Sisitemu yo gukingira uburyo bwinshi nimwe mumpamvu zingenzi Dacromet irusha isahani ya zinc isanzwe ndetse ikanashyuha-igashyirwa mubizamini byinshi byihuta.

Icyangombwa, kubera ko inzira ya Dacromet itarimo gufata aside ndetse no kudashyiramo electrolytike, ntabwo yinjiza hydrogène mumashanyarazi yicyuma. Ubu buryo bwibanze buranga Dacromet itwikiriye hydrogène yuzuye yubusa - inyungu ikomeye mugihe utwikiriye flang-tensile yo mu cyiciro cya 10.9, 12.9, cyangwa ASTM A490.

3. Ibyiza byingenzi bya Dacromet Flange Bolts

3.1 Kurwanya ruswa idasanzwe no kurwanya anti-rust

Dacromet isize flange bolts ihora igera kumasaha arenga 1.000 yo kurwanya umunyu utagira aho ubogamiye (ASTM B117 / ISO 9227) utagaragara nkumuyonga utukura. Mu byiciro byinshi byubucuruzi, ingese yera nayo itinda kurenza amasaha 240. Uru rwego rwimikorere yo kurwanya ingese rurenze kure urwego rusanzwe rwa electroplated zinc, rusanzwe rwerekana ingese zitukura mumasaha 72 kugeza 200 mugihe cyibizamini bimwe. Kurwanya ruswa irwanya Dacromet ituruka ku miterere yihariye ya flake hamwe nigikorwa cyo guhuza inzitizi, kurinda zinc ibitambo, hamwe na passivasi yimiti.

Mubidukikije-byukuri-ikirere cyo ku nkombe, inganda zikora inganda, inganda zikoresha amamodoka, hamwe na platifomu yo hanze - Dacromet flange bolts ikomeza ubunyangamugayo bwayo igihe kirekire kuruta icyuma gisanzwe. Ipitingi irinda neza kwangirika kwose hamwe no gutobora ahantu, byemeza ko bolt ikomeza gutanga imbaraga zokwizirika mubuzima bwa serivisi. Ubu bushobozi budasanzwe bwo kurwanya ingese busobanura mu buryo butaziguye amafaranga yo kubungabunga, guhagarika bike bitateganijwe, no kongera umutekano mu miterere.

3.2 Amashanyarazi ya Hydrogen Yuzuye

Kimwe mu byiza byingenzi bya Dacromet itwikiriye flange bolts ni uko isanzwe ari hydrogène yinjira kubuntu. Ibyuma bikomeye cyane birashobora kwibasirwa cyane na hydrogène yinjira, ibintu aho hydrogène ya atome ikwirakwira muri microstructure yicyuma, bikagabanya guhindagurika, kandi bishobora gutera kuvunika gutunguranye, gutinda kubera guhangayika. Inzira gakondo ya electroplating itanga hydrogène kuri cathode mugihe cyo guta ibyuma, ndetse no guteka neza nyuma yo kuyisiga ntibishobora kwemeza ko hydrogène ikuweho.

Kuberako Dacromet ari igikoresho kitari electrolytike gikoreshwa hatabanje kwitwa aside, nta hydrogène yinjizwa muri bolt mugihe cyo kurangiza. Ubushyuhe bwo hejuru bukiza burakomeza kwemeza ko ubushuhe bwose busigaye bwirukanwa. Igeragezwa ryinshi ryujuje ibyangombwa-harimo n’ubushakashatsi bushyigikira iyemezwa rya Dacromet kuri ASTM A490 yubatswe - yemeje ko Dacromet yometseho imbaraga zikomeye zigumana imbaraga zavunitse ndetse na nyuma yo kumara igihe kinini yibidukikije byangirika. Iyi hydrogène yinjizamo ubuntu iranga Dacromet igifuniko cyo guhitamo guhuza flange ihuza imiyoboro yumuyaga, ibiraro, ibikoresho byumuvuduko, hamwe na chassis yimodoka.

3.3 Gitoya, Igipfundikizo kimwe hamwe nigipfukisho cyiza

Bitandukanye na hot-dip galvanizing, ishyiramo umubyimba wa zinc ugereranije kandi rimwe na rimwe itaringaniye, Dacromet itanga igipfundikizo cyoroshye, gisa cyane gikurikiza geometrike yuzuye yimigozi ya bolt, munsi yumutwe wa radiyo, no mumaso ya flange. Ubu busabane burinda umurongo wateguwe kandi butuma umubano wukuri uterana mugihe cyo guterana. Uburyo bwa dip-spin uburyo bwo kwemeza ko na geometrike igoye, ahantu hasubiwemo, hamwe nubuso bwimbere bwa flange bolts yakira byimazeyo birinda ingese, bikuraho ibibanza bidakunze kugaragara bifitanye isano na elegitoronike.

3.4 Ubushyuhe bwo hejuru kandi burambye

Ipitingi ya Dacromet ikomeza guhagarara neza ku bushyuhe bwa serivisi ikomeza kugera kuri 300 ° C, ikarenga kure imipaka ifatika ya zinc isanzwe (itangira kwangirika nka 100-120 ° C). Uku kurwanya ubushyuhe ni ingirakamaro cyane cyane kumashanyarazi akoreshwa mubice bya moteri, sisitemu yo kuzimya, itanura ryinganda, nibikoresho bitanga ingufu. Byongeye kandi, firime ya Dacromet yakize yerekana uburyo bwiza bwo kurwanya ibyangiritse mugihe cyo kuyitunganya no kuyishyiraho, bikarinda kandi igihe kirekire kwangirika no kurwanya ingese ya bolt.
