一, Tsarin gwajin feshin gishiri
Matsayi daban-daban suna ba da tsarin gwaji daban-daban, wannan labarin zuwa GJB 150.11A-2009 "Hanyoyin gwajin muhalli na kayan aikin soja Sashe na 11: Gwajin feshin gishiri" a matsayin misali, bayyana tsarin gwajin gwajin gishiri, gami da takamaiman:
1.Ma'aunin gwajin gwajin gishiri: GJB 150.11A-2009
2.Gwaji yanki pretreatment: cire gurbatawa, kamar mai, man shafawa, kura, pretreatment ya zama kadan kamar yadda zai yiwu.
3.Gwajin farko: duban gani, idan ya cancanta, gwajin aikin lantarki da na inji, rikodin bayanan tushe.
4.Matakan Gwaji:
a.Daidaita yawan zafin jiki na dakin gwaji zuwa 35 ° C kuma ajiye samfurin don akalla 2 hours;
b.Fesa na tsawon sa'o'i 24 ko kamar yadda aka ƙayyade;
c.Bushe samfuran a zafin jiki na 15 ° C zuwa 35 ° C da ɗanɗano zafi wanda bai wuce 50% ba na awanni 24 ko na ƙayyadadden lokaci;
d.Maimaita aikin fesa gishiri da bushewa sau ɗaya don kammala zagayowar biyu.
5.Farfadowa: A hankali kurkura samfuran tare da ruwan gudu.
6.Gwajin ƙarshe: Binciken gani, gwajin aikin jiki da na lantarki idan ya cancanta, da rikodin sakamakon gwaji.
7.Binciken sakamako: Yi nazarin sakamakon gwajin daga bangarori uku: jiki, lantarki da lalata.
二, Abubuwan da ke shafar gwajin feshin gishiri
Babban abubuwan da suka shafi sakamakon gwajin feshin gishiri sun haɗa da: zafin gwajin da zafi, ƙaddamar da maganin gishiri, kusurwar jeri samfurin, ƙimar pH na maganin gishiri, adadin adadin gishiri da kuma hanyar fesa.
1) Gwajin zafi da zafi
Lalatawar gishiri ta samo asali ne daga martanin sinadarai na lantarki, inda zafin jiki da zafi ke taka muhimmiyar rawa wajen daidaita saurin wannan yanayin.Hawan zafin jiki yawanci yana haifar da saurin ci gaban lalatawar gishiri.Hukumar kula da fasahar lantarki ta kasa da kasa (IEC) ta haskaka wannan lamari ta hanyar yin nazari kan hanzarin gwajin gurbacewar yanayi, inda ta yi nuni da cewa karuwar 10°C na iya kara karfin lalata da kashi biyu zuwa uku, yayin da kuma kara karfin wutar lantarki da maki 10 zuwa 20. %.
Duk da haka, ba kawai haɓakar layi ba ne;Ainihin adadin lalata ba koyaushe yana yin daidai da hauhawar zafin jiki a madaidaiciyar hanya ba.Idan zafin gwajin gwajin ya yi tsayi da yawa, rashin daidaituwa tsakanin injin feshin gishiri da yanayin duniya na iya tasowa, yana yin tambaya game da amincin sakamakon.
Labarin ya bambanta da zafi.Karfe lalata yana da mahimmancin yanayin zafi na dangi, kusan 70%, bayan abin da gishiri ya fara narkewa, yana haifar da electrolyte.Akasin haka, yayin da matakan zafi ke raguwa, ƙwayar maganin gishiri yana ƙaruwa har sai hazowar gishirin crystalline ya auku, wanda ke haifar da raguwar raguwar lalata.Rawa ce mai laushi tsakanin zafin jiki da zafi, kowanne yana yin tasiri ga ɗayan ta hanyoyi masu rikitarwa, don tantance saurin da lalata ke tafiya gaba.
2)A pH na gishiri bayani
PH na maganin gishiri yana ɗaya daga cikin mahimman abubuwan da ke ƙayyade sakamakon gwajin feshin gishiri.Lokacin da pH ya kasance ƙasa da 7.0, ƙaddamar da ions hydrogen a cikin maganin yana ƙaruwa yayin da pH ya ragu kuma acidity yana ƙaruwa, don haka yana ƙaruwa da lalata.
3) Samfurin sanya kusurwa
Lokacin da gishirin gishiri ya faɗi kusan a tsaye, yanki da aka tsara na samfurin yana ƙaruwa idan samfurin yana cikin matsayi a kwance, wanda ya haifar da mafi tsananin yazawar saman samfurin ta hanyar fesa gishiri, kuma ta haka yana ƙara darajar lalata.
4)Matsakaicin maganin gishiri
Yadda maida hankali na maganin gishiri ke shafar adadin lalata ya dogara da nau'in kayan da abin rufewar sa.Lokacin da maida hankali bai wuce kashi 5 cikin dari ba, mun lura cewa yawan lalata na karfe, nickel da tagulla yana ƙaruwa yayin da ƙaddamar da maganin ya tashi;Sabanin haka, lokacin da maida hankali ya wuce kashi 5 cikin ɗari, ƙimar lalatawar waɗannan karafa yana nuna yanayin lalata daidai gwargwado ga karuwar taro.Koyaya, don karafa irin su zinc, cadmium da jan ƙarfe, ƙimar lalata koyaushe tana da alaƙa da daidaituwa tare da maida hankali na maganin gishiri, watau, mafi girman maida hankali, saurin lalata.
Ban da wannan kuma, abubuwan da suka shafi sakamakon gwajin feshin gishiri sun hada da: katsewar gwajin, maganin samfurin gwajin, hanyar feshi, lokacin feshi, da dai sauransu.
