Ikiganiro kigufi kijyanye no gupima umunyu ③

一 test Uburyo bwo gupima umunyu

Ibipimo bitandukanye bitanga inzira yikizamini gitandukanye gato, iyi ngingo kuri GJB 150.11A-2009 "ibikoresho bya gisirikare laboratoire uburyo bwo gupima ibidukikije Igice cya 11: ikizamini cyo gutera umunyu" nkurugero, sobanura uburyo bwo gupima ikizamini cyumunyu, harimo na:

1.Ikizamini cyo gupima umunyu: GJB 150.11A-2009

2.Kwipimisha ibice byo kwipimisha: kuvanaho umwanda, nkamavuta, amavuta, umukungugu, kwitegura bigomba kuba bike bishoboka.

3.Ikizamini cyambere: kugenzura amashusho, nibiba ngombwa, ibizamini byamashanyarazi nubukanishi, kwandika amakuru yibanze.

4.Intambwe yikizamini:

    a.Hindura ubushyuhe bwicyumba cyibizamini kugeza kuri 35 ° C hanyuma ugumane urugero byibuze amasaha 2;

    b.Koresha amasaha 24 cyangwa nkuko byavuzwe;

    c.Kama ingero ku bushyuhe bwa 15 ° C kugeza kuri 35 ° C hamwe nubushyuhe bugereranije butarenze 50% mumasaha 24 cyangwa mugihe cyagenwe;

   d.Ongera usubiremo umunyu hamwe nuburyo bwo kumisha inshuro imwe kugirango urangize inzinguzingo zombi.

5.Gukira: Koza witonze ukoresheje amazi.

6.Ikizamini gisoza: Igenzura ryerekanwa, ibizamini byumubiri nu mashanyarazi nibiba ngombwa, no kwandika ibisubizo byikizamini.

7.Isesengura ryibisubizo: Gisesengura ibisubizo byikizamini uhereye kubintu bitatu: umubiri, amashanyarazi na ruswa.

二 ors Ibintu bigira ingaruka ku kizamini cyo gutera umunyu

Ibintu by'ingenzi bigira ingaruka ku bisubizo by'ikizamini cyo gutera umunyu harimo: ubushyuhe bw'ikizamini n'ubushuhe, ubunini bw'umuti w'umunyu, inguni yo gushyira icyitegererezo, agaciro ka pH k'umuti w'umunyu, ingano yo gutera umunyu hamwe na uburyo bwo gutera.

1 temperature Gupima ubushyuhe n'ubushuhe

Kwangirika kwumunyu biterwa ahanini nubushakashatsi bwibikoresho byamashanyarazi, aho ubushyuhe nubushuhe bigira uruhare runini muguhindura umuvuduko wiyi reaction.Kuzamuka k'ubushyuhe mubisanzwe bituma iterambere ryihuta ryangirika ryumunyu.Komisiyo mpuzamahanga y’amashanyarazi (IEC) yamuritse iki kibazo binyuze mu bushakashatsi bwakozwe ku kwihutisha kwangirika kw’ikirere, avuga ko kwiyongera kwa 10 ° C bishobora kongera umuvuduko wa ruswa ku kigero cya kabiri kugeza kuri bitatu, ari nako bizamura amashanyarazi ya 10 kugeza kuri 20 %.

Nyamara, ntabwo ari ukuzamuka kumurongo gusa;igipimo nyacyo cyo kwangirika ntabwo buri gihe gihura nubushyuhe bwiyongera muburyo butaziguye.Niba ubushyuhe bwikigereranyo buzamutse cyane, hashobora kubaho itandukaniro riri hagati yuburyo bwo kwangiza umunyu wumunyu hamwe nukuri kwisi, bishobora gushidikanya kwizerwa ryibisubizo.

Inkuru iratandukanye nubushuhe.Kwangirika kwicyuma bifite aho bihurira nubushuhe bugereranije, hafi 70%, hejuru yumunyu utangira gushonga, bigakora electrolyte ikora.Ku rundi ruhande, uko ubuhehere bugenda bugabanuka, igisubizo cyumunyu cyiyongera kugeza igihe haguye imvura yumunyu wa kristaline, bigatuma umuvuduko wa ruswa ugabanuka.Ni imbyino yoroshye hagati yubushyuhe nubushuhe, buri kimwe kigira ingaruka mubindi muburyo bugoye, kugirango umenye umuvuduko ruswa igenda imbere.

2）PH yumuti wumunyu

PH yumuti wumunyu nimwe mubintu byingenzi muguhitamo ibisubizo byikizamini cyumunyu.Iyo pH iri munsi ya 7.0, kwibumbira hamwe kwa hydrogène ion mugisubizo byiyongera uko pH igabanuka na acide ikiyongera, bityo bikongera ruswa.

3 ingero z'icyitegererezo

Iyo spray yumunyu iguye hafi ya vertike, agace kateganijwe kicyitegererezo kiyongera niba icyitegererezo kiri mumwanya utambitse, bikaviramo isuri rikabije ryubuso bwicyitegererezo ukoresheje spray yumunyu, bityo bikongerera urugero ruswa.

4）Kwibanda kumuti wumunyu

Ukuntu kwibumbira hamwe kwumuti wumunyu bigira ingaruka kumuvuduko wa ruswa biterwa nubwoko bwibintu no gutwikira hejuru.Iyo kwibumbira hamwe bitarenze 5 ku ijana, turareba ko igipimo cyo kwangirika kwibyuma, nikel n'umuringa byiyongera uko kwibanda k'umuti kuzamuka;muburyo bunyuranye, iyo kwibumbira hamwe birenze 5 ku ijana, igipimo cyo kwangirika kwibi byuma cyerekana impengamiro yo kwangirika ku buryo butandukanye no kwiyongera kwinshi.Nyamara, ku byuma nka zinc, kadmium n'umuringa, igipimo cya ruswa gihora gifitanye isano neza no kwibumbira hamwe k'umuti w'umunyu, ni ukuvuga, uko kwibanda cyane, niko umuvuduko wa ruswa wihuta.

Usibye ibi, ibintu bigira ingaruka kubisubizo byikizamini cyo gutera umunyu harimo: guhagarika ikizamini, kuvura urugero rwikizamini, uburyo bwo gutera, igihe cyo gutera, nibindi.
