Ese ingese y'ibishingiriro by'icyuma gishongeshejwe yanduza aho icumba kidafunguye? Igikoresho cya granite cya ZHHIMG cyaremewe.

Mu nganda nka semiconductors na electronics zigezweho, zifite ibisabwa bikomeye cyane ku bijyanye n'umusaruro, isuku y'aho hantu hatari ivumbi igira ingaruka ku musaruro w'ibicuruzwa. Ikibazo cy'umwanda uterwa no kwangirika kw'ibyuma bisanzwe birimo kuba ikibazo kitoroshye ku bigo. Ariko, igisubizo cya granite cya ZHHIMG cyatsinze icyemezo cyemewe n'imikorere yacyo myiza, kizana iterambere rishya mu nganda.

Nubwo ishingiro ry'icyuma gishongeshejwe rikoreshwa cyane mu nganda, ubushobozi bwacyo bwo kurwanya ingese buragaragara neza mu bidukikije by'aho bitarimo ivumbi. Inkingi ishongeshejwe ahanini igizwe n'icyuma na karuboni, kandi ikunze kwibasirwa cyane n'imikorere ya ogisijeni hamwe na ogisijeni n'ubushuhe mu kirere, bigatuma habaho ingese. Mu icumbi ridafite ivumbi, ndetse n'ingese nkeya zivuyemo zishobora gutuma ibyuma bifutuka. Iyo utwo duce twinjiye mu bikoresho by'ubuziranenge cyangwa tugafata ku buso bw'ibicuruzwa, dushobora guteza ingaruka zikomeye nko gufunga ibyuma bigufi mu byuma bya semiconductor no kwanduza ibice by'ubuziranenge bw'amatara, bikongera cyane igipimo cy'ubuziranenge bw'ibicuruzwa. Dukurikije imibare y'inganda, ibibazo by'ubuziranenge bw'ibicuruzwa biterwa n'ubuhumane bw'ishingiro ry'icyuma gishongeshejwe bigira uruhare runini kuri 15% kugeza kuri 20% by'ubukene bw'umusaruro mu icumbi ridafite ivumbi.

Umuti wa ZHHIMG granite wasubije cyane ku ngaruka z'umwanda ku byuma bicukurwa. Granite igizwe ahanini n'amabuye y'agaciro nka quartz na feldspar. Ifite imiterere ihamye cyane ya shimi, ifite ubushobozi bwo kwihanganira pH kuva kuri 1 kugeza kuri 14. Ntishobora gukorana na aside cyangwa alkaline chemical reagents kandi ntijya ihinduka ogisijeni hamwe na ogisijeni cyangwa ubushuhe mu kirere. Kubwibyo, nta kibazo cyo kugwa ingese. Hagati aho, imiterere yayo ikomeye (porosity < 0.1%) ituma ubuso bwayo burushaho kuba bwiza kandi bugororotse, kandi ntibyoroshye gukurura umukungugu n'ibintu bihumanya. Nubwo ikoreshwa igihe kirekire ahantu hatari umukungugu hakenewe isuku nyinshi, iracyashobora kugumana isuku, yirinda ingaruka mbi ku bicuruzwa biterwa n'umwanda w'ibanze.

Igikwiye kwitabwaho kurushaho ni uko umuti wa ZHHIMG granite watsinze icyemezo cya ISO 14644-1 cyo mu cyiciro cya 5 cy’icyumba cyo kunyweramo isuku. Iki cyemezo gifite ibisabwa byihariye ku bijyanye n’ubwinshi bw’uduce duto two mu kirere. Mu mezi atatu yikurikiranya y’ibizamini bikomeye, ishingiro rya ZHHIMG granite ryakomeje kugumana igipimo cyo gusohora uduce duto cyane, rituma ritangiza umwanda mu bidukikije bitagira ivumbi. Byongeye kandi, urubuga rwa granite rufite kandi ubushobozi buke cyane bwo kwaguka k’ubushyuhe n’ubudahangarwa bwiza bwo guhindagurika. Nubwo rwemeza ko isuku y’aho bikorerwa isuku itagira ivumbi, rushobora gutanga inkunga ihamye ku bikoresho by’ubuziranenge, rukongera imikorere myiza n’ubwizerwe bw’ibikoresho.

Nyuma y’uko ikigo kizwi cyane gikora ibikoresho bya semiconductor gikoresheje umuti wa ZHHIMG granite kugira ngo usimbuze ishingiro ry’icyuma gishongeshejwe, igipimo cy’inenge cy’ibicuruzwa byacyo giterwa n’umwanda cyagabanutse cyane kiva kuri 8% kigera kuri 1.5%, umusaruro wiyongereyeho 25%, kandi ikiguzi cyagabanutse ku mwaka bitewe no gukurwaho kw’ibicuruzwa cyarenze miliyoni 10 z’amayuani. Iki gikorwa gitangaje kigaragaza neza agaciro k’umuti wa ZHHIMG granite mu gukemura ibibazo by’umwanda mu mazu akorerwamo imirimo yo kuvura ivumbi.

Bitewe no kunoza imikorere y’ubuziranenge bw’ibicuruzwa n’ibisabwa mu nganda zitandukanye, akamaro k’amaduka adafite ivumbi kararushaho kugaragara. Ibikoresho bya ZHHIMG granite, bifite imiterere yabyo idakira ingese, isukuye kandi ihamye, ndetse n’ubufasha bwemewe bwo kwemeza, bitanga amahitamo yizewe ku bigo, bigafasha inganda kugera ku nganda zikora neza kandi zifite ubuziranenge.
