Ese ibikoresho byawe by'icyuma biraramba? Dore impamvu gupima umunyu ari ngombwa!

Ese wigeze uhura n'iki kibazo? Ibice by'icyuma by'ibikoresho by'amatara waguze bitangira kugaragaza ibimenyetso bya corruption hejuru nyuma y'igihe ukoresheje. Ibi bigaragaza neza ko ubwiza bw'ibikoresho nk'ibi by'amatara butari ku rwego rwo hejuru. Niba ushaka kumenya impamvu y'ibi, uyu munsi turagaragaza ko byose bifitanye isano rya bugufi no "gupima umunyu"!

Ikizamini cyo gupima umunyu (Salt Spray Test) ni iki?

Ikizamini cya Salt Spray ni ikizamini cy’ibidukikije gikoreshwa mu gusuzuma ubushobozi bw’ibicuruzwa cyangwa ibikoresho by’icyuma bwo guhangana n’ingufu. Gishushanya ibidukikije bya spray y’umunyu kugira ngo gisuzume uburyo ibikoresho biramba muri ubwo buryo no gusuzuma imikorere yabyo n’igihe bimara mu bidukikije byangiritse.

Ishyirwa mu byiciro ry'igerageza:

1. Ipfapfa ry'umunyu utagira aho ubogamiye (NSS)

Isuzuma rya Spray y'umunyu utagira aho ubogamiye ni bwo buryo bwa mbere kandi bukoreshwa cyane mu gupima ingese. Muri rusange, ikoresha umuti wa 5% by'amazi y'umunyu wa sodium chloride ufite pH ihinduka ku rugero rwa neutral (6.5-7.2) mu gukoresha spray. Ubushyuhe bw'isuzuma buguma kuri 35°C, kandi igipimo cyo gushyiramo umunyu gisabwa kuba hagati ya 1-3 ml/80cm²·h, ubusanzwe 1-2 ml/80cm²·h.

2. Ifuro ry'umunyu wa aside asetiki (AASS)

Ikizamini cya aside acetic umunyu cyakozwe hifashishijwe ikizamini cya aside acetic umunyu. Gikubiyemo kongera aside acetic glacial mu gisubizo cya sodium chloride 5%, bikagabanya pH kugera kuri 3, bigatuma igisubizo kiba aside, bityo bigatuma igihu cy'umunyu kiva kuri aside kijya kuri aside. Igipimo cyayo cya corruption cyihuta inshuro eshatu ugereranyije n'ikizamini cya NSS.

3. Ipfapfaizwa ry'umunyu rya Acide Acetic Acid (CASS) rikoresha umuringa (Copper Accelerated Acide Acetic Salt Spray)

Ikizamini cyo gupima aside y’umunyu ya Copper Accelerated Acetic Salt Spray Test ni ikizamini cyo gupima aside y’umunyu cyakozwe vuba aha mu mahanga. Ubushyuhe bw’ikizamini ni 50°C, hamwe n’umunyu muto w’umuringa (chloride y’umuringa) wongewe mu gisubizo cy’umunyu, ibyo bikaba byihutisha cyane ingese. Igipimo cyayo cyo gupima ingese cyihuta inshuro zigera kuri 8 ugereranije n’ikizamini cya NSS.

4. Ifuro ry'umunyu risimburanya (ASS)

Ikizamini cyo gutera umunyu mu buryo bunyuranye ni ikizamini cyuzuye cyo gutera umunyu gihuza gutera umunyu mu buryo butari bwo hamwe n’ubushuhe buhoraho. Gikoreshwa cyane cyane ku bikoresho by’imashini yose, bigatuma umunyu utera ingese atari ku buso bw’ibicuruzwa gusa ahubwo no imbere mu gihe cy’ubushuhe. Ibicuruzwa binyura mu bihe bitandukanye hagati y’ibihu by’umunyu n’ubushuhe, bigasuzuma impinduka mu mikorere y’amashanyarazi n’iy’imashini yose.

Ese ibikoresho by'urumuri bya Liper nabyo byapimwe umunyu?

Igisubizo ni Yego! Ibikoresho by'icyuma bya Liper byo gukora amatara n'amatara bikorwa hakurikijwe amahame mpuzamahanga. Hashingiwe ku gipimo cya IEC60068-2-52, bikorerwa ikizamini cyihuse cyo kwangirika gikubiyemo ikizamini gikomeza cyo gutera imiti mu gihe cy'amasaha 12 (ku bijyanye no gusiga icyuma). Nyuma y'ikizamini, ibikoresho byacu by'icyuma ntibigomba kugaragaza ibimenyetso bya oxidation cyangwa ingese. Icyo gihe ni bwo ibikoresho by'urumuri bya Liper bishobora kugeragezwa no kwemezwa.

Turizera ko iyi nkuru ifasha abakiriya bacu gusobanukirwa akamaro ko gupima umunyu. Mu guhitamo ibikoresho by'urumuri, ni ngombwa guhitamo amahitamo meza. Muri Liper, ibicuruzwa byacu bikorerwa isuzuma rikomeye, harimo ibizamini byo gupima umunyu, ibizamini byo kumara igihe kirekire, ibizamini bitagira amazi, no gupima imiterere y'umubumbe, nibindi.

Uku kugenzura neza ubuziranenge kwemeza ko abakiriya ba Liper babona ibikoresho by'urumuri byiza kandi byizewe, bityo bikazamura ubuzima bw'abakiriya bacu ndetse n'ibyishimo muri rusange.

Nk'uruganda rw'amatara rwabigize umwuga, Liper ikora neza cyane mu guhitamo ibikoresho, bigatuma uhitamo no gukoresha ibicuruzwa byacu ufite icyizere.
