Dacromet-Yashizweho Hex Bolts 

1. Intangiriro

Hex bolts (hexagon head bolts) iri mubintu bikoreshwa cyane mubwubatsi, imashini, guteranya amamodoka, nibikorwa remezo. Mubidukikije byangirika - inyubako zo ku nkombe, ibihingwa ngandurarugo, umuhanda munini, ibiraro, niminara yo hanze - ubuzima bwumurimo wurugingo ruhindagurika akenshi butagaragazwa nimbaraga zicyuma, ahubwo nigihe kirekire cyo gutwikira.

Ipitingi ya Dacromet (izwi kandi nka DACROMET, Dacromet zinc-flake, cyangwa zinc-aluminium flake coating) ni amazi ashingiye kumazi-ya-barrière ikoreshwa na dip-spin cyangwa spray kandi ikiza mubushyuhe buke. Kuva ryatangizwa muri Amerika mu myaka ya za 70 ndetse n’inganda zaje gukurikiraho mu Buyapani no mu Burayi, Dacromet yabaye igisubizo nyamukuru cyo gukingira ruswa ikingira ingufu zikomeye cyane cyane mu cyiciro cya 8.8 no hejuru yacyo, aho gakondo ya hot-dip galvanizing itwara ibyago byo kwinjiza hydrogène hamwe n’ibibazo byo mu rwego.

2. Hex Bolt ya Dacromet isize iki?

Dacromet isize hex bolt ni igihanga gisanzwe cya hexagon (kuri ISO 4014 / ISO 4017 / DIN 931 / DIN 933 cyangwa ASME B18.2.1) ubuso bwabwo bwarinzwe nigitambaro gishingiye kuri zinc-flake gikoreshwa mumazi ashingiye kumazi arimo:

• Zinc flake na aluminium- inzitizi ikora ya ruswa-kurinda (igipimo gisanzwe hafi 75% Zn / 25% Al kubintu bikomeye);
• Chromium ivanze cyangwa chromium idafite passivator- gutanga passivation yo kwikiza ahantu hakeye;
• Inganda zidasanzwe hamwe na selile ya selile- guhuza flake muri firime yuzuye, yubahiriza;
• Amazi yimana- gutwara ibintu bitwara, gukora inzira VOC idafite kandi yangiza ibidukikije.

Igipfundikizo gikoreshwa mukwibiza (cyangwa gutera) bigakurikirwa no kuzunguruka hagati kugirango ukureho umwanda mwinshi, hanyuma ukira hafi 280–330 ° C muminota 20-40. Inzinguzingo nyinshi zo kuzunguruka (mubisanzwe ebyiri) zubaka uburebure bwa 6-10 mm; ibyiciro biremereye bigera kuri 12-15 mm.
