Ni ubuhe bushyuhe bwo kugurisha ukurikirana?

Mubihe byinshi, ikintu kinini kigira ingaruka kumibereho yakugurisha icyumainama ni ubushyuhe bwo kugurisha.

Mbere yo gushyira mu bikorwa ku mugaragaro amabwiriza ya RoHS (kubuza ibintu bishobora guteza akaga) ku ya 1 Nyakanga 2006, biremewe kuyobora insinga zagurishijwe.Nyuma yibyo, birabujijwe gukoresha isasu (nibintu bifitanye isano) birabujijwe usibye ibikoresho nibikorwa bikurikira: ibikoresho byubuvuzi, ibikoresho byo gukurikirana no gutahura, ibikoresho byo gupima nibikoresho cyane cyane mubice bya gisirikare no mu kirere harimo ibyuma bikoresha amamodoka (sisitemu yo kugenzura ibinyabiziga nibicuruzwa bikoresha indege) ), inganda zitwara gari ya moshi, n'ibindi.

Ikunze kugaragara cyane cyitwa alloy tin wire irangwa no gushonga nka dogere 180.Gushonga ingingo isanzwe idafite isukari ya tin wire ni dogere 220.Itandukaniro ryubushyuhe bwa dogere 40 bivuze ko kugirango urangize nezaugurishagufatanya mugihe kimwe, dukeneye kongera ubushyuhe bwa sitasiyo yo kugurisha (niba igihe cyo kugurisha cyiyongereye, biroroshye kwangiza ibice nubuyobozi bwa PCB).Ubwiyongere bwubushyuhe buzagabanya ubuzima bwa serivisi yo kugurisha ibyuma no kongera okiside.

Igishushanyo gikurikira cyerekana ingaruka zubushyuhe bwiyongera kubuzima bwa serivisi yo kugurisha icyuma.Gufata dogere 350 nkigiciro cyerekanwe, mugihe ubushyuhe bwiyongereye kuva kuri dogere 50 kugera kuri dogere 400, ubuzima bwumurimo wicyuma cyo kugurisha kizagabanukaho kimwe cya kabiri.Kongera ubushyuhe bwa serivisi ya fer yo kugurisha bivuze ko ubuzima bwa serivisi yo kugurisha icyuma bugabanuka.

Mubisanzwe, ubushyuhe bwa soldeirng yubusa butagurishijwe bugurishwa bisabwa kuba 350 ℃.Ariko, kurugero, kubera ko ubunini bwa 01005 igikoresho cyo kwishyiriraho ari gito cyane, turasaba inzira yo kugurisha dogere 300.

Akamaro ko kumenya ukuri

Ugomba kugenzura ubushyuhe bwakazi bwa sitasiyo igurisha buri gihe, ntibishobora kongera ubuzima bwumurimo wicyuma cyo kugurisha, ariko kandi wirinde ubushyuhe bukabije cyangwa kugurisha ubushyuhe buke mugihe cyo kugurisha ibicuruzwa.

Byombi birashobora gutera ibibazo mugihe cyo kugurisha:

· Ubushyuhe bukabije: abashoramari benshi bahuguwe bazatekereza ko ari ngombwa kongera ubushyuhe bwo kugurisha kugirango bakemure ikibazo mugihe basanze uwagurishije adashobora gushonga vuba.Ariko, kongera ubushyuhe bizatuma ubushyuhe bwahantu hashyuha cyane, bizatuma habaho ipadiri, ubushyuhe bukabije bwabagurisha, byangiza substrate hamwe nugurisha hamwe nubwiza bubi.Muri icyo gihe, bizongera okiside yumutwe wicyuma kandi byonone kwangirika kwicyuma.

· Ubushyuhe buke bwo kugurisha burashobora gutuma umuntu abaho igihe kinini mugikorwa cyo kugurisha no guhererekanya ubushyuhe bukabije.Ibi bizagira ingaruka kubushobozi bwo gukora hamwe nubwiza bwibicuruzwa bikonje.

Kubwibyo, gupima ubushyuhe nyabwo ni ngombwa kugirango ubone ubushyuhe bwo kugurisha.
