Ukukhetha inzwa yeleveli ye-TN efanele yohlelo lwakho lokusebenza kungaphezu kokunemba nje — kumayelana nokufanisa okokusebenza kwenzwa nokuklama nezinto ezibonakalayo nezamakhemikhali zoketshezi olulinganiswayo. Noma ngabe usebenzisana namanzi ahlanzekile ethangini noma amakhemikhali abola kakhulu kulayini wokucubungula, izinto ezithinta uketshezi zidlala indima ebalulekile ekusebenzeni, ukuphila isikhathi eside, nokuphepha. Kwa-Bluefin Sensor Technologies Limited, sichithe iminyaka eminingi izisombululo zeleveli yobunjiniyela ezihlangabezana ngokuthembekile nezidingo zezimboni ezihlukahlukene, futhi siyaqonda ukuthi ukukhetha kwezinto ezibonakalayo kungenza noma kuphule kanjani isicelo sezinzwa.
Ukuqonda Izinzwa Zeleveli Ye-TN Nokuhambelana Kwezinto
A Inzwa yeleveli ye-TN (inzwa yenethiwekhi/izinga lethangi eshintshwayo) ithola amazinga oketshezi isebenzisa izimiso ezifana namandla, ukuqhutshwa kwe-conductivity, noma ukudlidliza kwemfologo, kuye ngedizayini. Kungakhathaliseki ubuchwepheshe, izingxenye ezimanzi - lezo ezihlangana noketshezi - kufanele zihambisane nekhemistri yoketshezi.
Ukuhambisana kwezinto kuthinta:
· Ukumelana nokugqwala
· Ukuphila kwenzwa
· Ukunemba kokulinganisa
· Imvamisa yesondlo
· Ukuhambisana nokuphepha
Ukukhetha izinto ezisebenza kabi noketshezi kungaholela ekulimaleni okusheshayo, ukufundwa okungamanga, isikhathi sokuphumula, ngisho nokwehluleka okuyingozi. Ngokuphambene, izinto ezimataniswe kahle zisiza ukuqinisekisa ukusebenza okungaguquki, okuzinzile phakathi neminyaka yokusebenza.
Kungani Ukukhetha Okubalulekile Kubalulekile Ekonakalisweni Kuqhathaniswa Noketshezi Olungenakonakala
Uketshezi olungagqwali njengamanzi noma izixazululo ze-alkaline ezithambile ngokuvamile azihlaseli izinsimbi ezivamile, amapulasitiki, noma okokunamathela. Kodwa-ke, uketshezi olubolayo - ama-asidi, izisekelo, izincibilikisi, izixazululo zikasawoti - zingasabela ngobudlova ngezinsimbi nama-polymer, okuholela ekuwohlokeni noma ekungcolisweni.
Ngokwesibonelo:
Insimbi engagqwali 304 isebenza kahle ngamanzi aphuzwayo kodwa ingangena endaweni ye-chloride.
· I-PTFE (Teflon) imelana namakhemikhali amaningi anolaka kodwa ingase ingamelani namazinga okushisa aphezulu.
· Ama-Hastelloy alloy ayachuma ezindaweni ezigqwala kakhulu kodwa eza ngezindleko eziphezulu.
Ukuqonda imvelo yamakhemikhali nezimo zokusebenza (izinga lokushisa, ingcindezi, isivinini soketshezi, ukungcola) kuyisihluthulelo sokukhetha izinzwa ezifanele.
