Ibipimo ngenderwaho bya HDG byo gusiga zinc pole street pole n'ibisabwa ku bugari

Gukoresha galvanizing ishyushye ni inzira y'ingenzi yo gukumira ingese no kwangirikainkingi z'amatara z'icyuma. Ubunini n'ubugari bw'igitambaro cya zinc bigena neza ubuzima bw'inkingi y'urumuri. Amasosiyete menshi y'ubwubatsi agura n'ay'ubwubatsi akenshi ntabwo asobanutse neza ku bipimo ngenderwaho by'igihugu, ibyiciro by'ubunini, n'ibisabwa mu guhangana n'ahantu habera. Muri iki gihe, uruganda rw'inkingi z'amatara yo hanze rwa Tianxiang ruzasobanura mu buryo burambuye ibipimo ngenderwaho byo gushyira mu bikorwa inkingi z'urumuri za HDG, ibipimo by'ubunini bw'igitambaro cya zinc ku bunini butandukanye bw'inkuta, n'ibipimo byo guhitamo ahantu habera inkombe no mu gihugu, bigufasha kwirinda ingorane z'igitambaro gito n'ibikoresho bitari ibisanzwe.

I. Amahame Rusange yo Gushyira mu Bikoresho by'Amatara yo mu Mihanda ya HDG

Nk'igikoresho cy'ingenzi mu byuma bitanga amatara mu mihanda no mu by'ubwubatsi, irangi rya zinc ry'inkingi z'amatara yo ku muhanda ya HDG ni ingenzi cyane mu kugena ingese n'uburinzi bw'ingese no kurinda ingese no kumara igihe cyazo. Imishinga yo mu gihugu muri rusange ikurikiza amahame ngenderwaho ya GB/T 13912-2022 “Irangi ry'icyuma – Ibisabwa mu bya tekiniki n'uburyo bwo gupima irangi ry'icyuma rishyushye rikoreshwa mu byuma”. Hagati aho, imishinga yo kohereza mu mahanga n'ubucuruzi bw'ubucuruzi bw'amahanga izibanda ku mahame mpuzamahanga ya ISO agenga irangi.

Ibipimo birumvikana ko inkingi yose y'urumuri rw'icyuma ikoresha uburyo bwo gushyushya umubiri wose, ikabuza gusa gusukura hejuru cyangwa gukoresha igice cya galvanizing. Nyuma yo gusya, gukuraho ingese, no gukurura, icyuma gishyirwa mu bwogero bwa zinc bushyushye cyane kugira ngo habeho urwego rwa zinc rufatanye n'icyuma. Uru rwego rufite ubushobozi bukomeye bwo gufatana kandi ntirworoshye gukuraho, bigatuma rubera ahantu hagoye ho hanze nko mu mirima ifunguye, mu nkengero z'inyanja, no mu bice bitose kandi bifite umunyu. Ni yo shingiro ry'uburinzi bw'ingese ku nkingi z'urumuri rwo ku muhanda.

II. Ibisabwa mu gushyira mu byiciro ubunini bw'urukuta rushyushye

1. Ibipimo by'ubunini bushingiye ku bunini bw'inkuta z'inkingi

- Ubunini bw'urukuta < 4mm: Ubunini bw'urwego rwa zinc budashyira munsi ya 55μm, hamwe n'ubunini bw'aho hantu budashyira munsi ya 45μm. Ikoreshwa cyane cyane ku nkingi nto zo mu gikari n'inkingi z'amatara zo mu muhanda za metero 3-5.

- Ubunini bw'urukuta 4mm～6mm: Ubunini bw'urwego rwa zinc ruhuriweho na 70μm, hamwe n'ubunini bw'aho buherereye nibura 55μm. Ku giti cy'urukuta gisanzwe gifite metero 6-10.

- Ubunini bw'urukuta > mm 6: Igipimo mpuzandengo cya Zinc kiri munsi ya 85μm hamwe n'aho nibura 70μm. Gikoreshwa ku rumuri rurerure rw'umurambararo ruri hejuru ya metero 12, umuhanda munini w'umujyi, n'inkingi z'amatara yo mu muhanda.

2. Kwiyongera k'ubusabe mu buryo butandukanye bwo gukoresha

Imihanda isanzwe yo mu mijyi no mu cyaro: Ubugari bw'imihanda busanzwe mu gihugu burahagije, kandi igihe cyo kuyikoresha ni imyaka 15-20.

Ahantu ho gusukura umunyu ku nkombe, pariki z’inganda zikoresha imiti, ahantu hatose kandi hatose: aho gutwikira hashyushye hagomba gukongerwa kugeza ku bunini bwa μm zirenga 100 kugira ngo hongere ubushobozi bwo kurwanya isukari y’umunyu n’ubushyuhe bwa aside/alkali kandi bigabanye umuvuduko w’ubushyuhe n’ingufu bya zinc.

III. Kwemera Ubuziranenge bwa Zinc Coating—Ibisabwa bike

1. Ubwiza bw'isura

Ubuso bumwe kandi bworoshye, nta gufunga ibyuma ku buryo butuzuye, uduheri, gukurura, utudomo n'ibibara by'umukara. Udupfundikizo, imiyoboro n'udupfundikizo bigomba kuba bidafite impande zapfuye kandi nta gufunga ibyuma ku buryo butuzuye.

2. Igipimo ngenderwaho cyo gufata neza

Igipfundikizo cya zinc ntikigomba kwangirika cyangwa gushwanyagurika mu gihe cyo gukubita no gupima ibice, kandi kigomba gufatanywa neza n'icyuma gikozwe mu cyuma.

3. Uburyo bwo gupima

Igenzura ry’ingero nyinshi hakoreshejwe icyuma gipima ubunini bwa zinc. Igice cyo hejuru, cyo hagati, n’icyo hasi cy’inkingi n’ishingiro rya flange bigomba kuba byujuje ubuziranenge. Iyo hari ingero zananiwe, igice cyose kigomba kongera gusuzumwa no kuvugururwa.

Ubunini bw'icyuma gishyushye gipima neza igihe inkingi z'amatara zikoreshwa hanze. Gutanga ibikoresho by'ubuhanga ndetse no guhindura imiterere y'inganda bigomba guhuza neza n'ubunini bw'icyuma gishyushye gihuye n'ubunini bw'inkuta z'igihugu.Uruganda rw'amatara yo hanze rukora inkingi z'amatara zikozwe mu mataraTianxiang yanze gukoresha ibyuma bitagira ingano bikoreshwa mu gucana kugira ngo imishinga y'amatara ikomeze gukoreshwa mu buryo burambye.
