Muri iki gihe, gukuraho gusa ibice by'icyuma gusa ntabwo bihagije. Abakoresha benshi bakeneye gukurura impande z'ibice by'icyuma. Ariko se uzi ingano y'urukiramende? Ni gute wamenya ingano ikwiye y'urukiramende?
Igisubizo gishingiye ku ntego y'agace k'icyuma. Ikigo gitunganya ibikoresho kigomba gutunganya ibice by'icyuma hakurikijwe ibisabwa mu gushushanya. Muri rusange, ibi bisabwa bigomba kuba ari ukuri kandi bidahinduka. Niba bigaragara mu gishushanyo cy'umusaruro ko agace k'icyuma kagomba kuba gazengurutse, ibisobanuro bya chamfer bizagira ingaruka zikomeye ku giciro cy'igikoresho. Kubwibyo, haba ku ruganda ubwarwo cyangwa ku kigo gitunganya, ni ngombwa cyane guhitamo neza ingano ya chamfer ikwiye.
Haza ibyo ukeneye nk'ishingiro, bike bishoboka
Kugira ngo ibikoresho byo gutunganya ibikoresho byo hasi bikoreshwe neza kandi mu buryo bwizewe, ibice by'icyuma bigomba kuba byoroshye kandi bidafite uduce duto. Ibi bikoresho byo hasi bishobora kuba imashini zicana, imashini zicurana cyangwa imashini zipima. Mbere yo kunama cyangwa gupima, niba ibikoresho bidafite uduce duto, nta mpamvu yo kuzunguruka, kuko agakoresho ko kuzunguruka gakunze kwangirika gusa n'uduce twazamuwe. Ibyo ni ko bimeze no ku bindi bikoresho nko gucura no gukata. Kubwibyo, ibice bidafite uduce duto birakwiriye cyane mu gutunganya nyuma.
Kugira ngo abakozi wirinde gushwanyaguzwa, ubunararibonye bwagaragaje ko hakenewe gusa chamfer ya 0.1mm kugira ngo umutekano ube mwiza. Ndetse n'uturindantoki twa latex, imiyoboro y'umwuka cyangwa insinga zikunze gukora ku nkengero z'ibice by'icyuma ntibizangirika n'ibice by'icyuma bifite uburebure buri munsi ya 0.1mm.
Iyo hatekerejwe ku gusiga, ibintu bigira ingaruka biba ingorabahizi kandi bitandukanye. Icya mbere ni ubwoko bw'igitambaro (KTL, ifu, irangi ritose), ubwoko n'ubwiza bw'igitambaro, hanyuma ibipimo by'ibikoresho, nko kubanza gusukura, igihe cyo kumisha cyangwa ubushyuhe bwo kumisha, kugeza igihe ibicuruzwa bishyizwe mu mwanya wa nyuma. Ibi bintu, hamwe n'umurambararo w'inkombe, bigira uruhare runini mu gihe cyo kurinda ingese. Kubwibyo, ingano ikwiye y'igitambaro igomba kugenwa binyuze mu isuzuma kugira ngo yongere igihe cyo kurinda ingese. Birumvikana ko ibindi bintu byose bigira ingaruka bigomba kugumaho mu isuzuma.
Ingano nto ya mm 0.5 itanga irangi ryizewe
Dukurikije DIN EN ISO 9227:2017, “ikizamini cya spray y’umunyu utagira aho ubogamiye NSS” gikunze gukoreshwa nk'uburyo bwo gupima uburinzi bw’uburozi. Uburyo bwo gushonga bufatwa uko igihe kigenda gihita. Byongeye kandi, igice gishobora gukorwa kugira ngo cyerekane impinduka z'ubugari bw'igipfundikizo, kugira ngo hapimwe ingano y'icyitegererezo (ibipimo by'inyongera bishobora gukorwa bibaye ngombwa). Izi ngero zishobora kandi kwerekana neza ko imiterere y'umunyu igira ingaruka ku bugari bw'igipfundikizo. Mu gihe cy'ifillet idahuje, ubugari bw'igipfundikizo bugabanuka ku buryo ntarengwa bwo gushonga. Kubwibyo, byafatwa umwanzuro ko ingaruka nziza yo kuzunguruka ku nkengero ishobora kuboneka hamwe n'umunyu uhuye.
Igipimo dushobora kubona muri ibi (urugero, ku nyubako z'ibyuma cyangwa inyubako zo mu mazi) gisaba ko uburebure bw'inkombe z'ibice bimwe by'icyuma ari 2.0mm cyangwa birenga. Ariko, ikoreshwa ryinshi mu buryo bufatika rigaragaza ko gupfuka neza bishobora kuboneka igihe cyose uburebure bwa 0.5mm bukozwe ku bice by'icyuma. Kubera ko ingano ya chamfer n'igiciro cy'ibikoresho bivamo biziyongera ukurikije ubwiyongere bw'inkombe z'inkombe, ni ngombwa ko abakoresha bashaka ingano ikwiye yo gupfuka kugira ngo barebe ko imashini yizewe kandi ihendutse. Ni ukuvuga: guhaza ibyo bakeneye, bike bishoboka.
