Kumlinganiselo wenkqubo, enye yempendulo esisiseko kumemo wokulinganisa onomhlwa kukusebenzisa imathiriyeli efanelekileyo ekwaziyo ukumelana nokubola kwenxalenye emanzi yesixhobo, idiaphragm ezivayo okanye utyatyeko lwaso, i-electronic case okanye amanye amalungu afunekayo kunye nezifakelo.
I-PTFE:
I-PTFE(i-Polytetrafluoroethylene) lolunye uhlobo lweplastiki yobunjineli ethambileyo, ekhaphukhaphu kunye ne-low-friction enokumelana nokugqwesa kweekhemikhali. Sisisombululo esinexabiso eliphantsi kwimeko enobundlobongela ekusetyenzweni kweekhemikhali kunye ne-oyile kunye namashishini egesi. Nangona kunjalo, kufuneka iqaphele ukuba i-PTFE ayisebenzi kubushushu bokusebenza obugqithileyo ngaphezulu kwe-260℃, ubulukhuni obuphantsi buyenza ingafaneleki ukuba ngumsonto okanye imathiriyeli ye-diaphragm.
Tantalum:
I-Tantalum sisinyithi esikwaziyo ukumelana nomhlwa ngendlela ekhethekileyo, ekwaziyo ukumelana neekhemikhali ezahlukeneyo ezinobundlongondlongo, nto leyo eyenza ukuba ibe yeyona ndlela ibalaseleyo yokuva imathiriyeli ye-diaphragm kumajelo eendaba ezonakalisa kakhulu. Nangona kunjalo, isinyithi sibiza kakhulu kwaye asisetyenziswa ngokuqhelekileyo njengezinye izinto. Kwinkqubo yekhemikhali elawula iiasidi ezinobundlongondlongo ngokugqithisileyo, inzwa yoxinzelelo ene-tantalum sensing diaphragm ifaneleke ngokugqibeleleyo kwisikhundla sokufikelela elona nqanaba liphezulu lokumelana nomhlwa.
I-Ceramic:
I-Ceramic yinto efanelekileyo ye-inorganic non-metallic ebonisa ukuxhathisa okubalaseleyo kubushushu obuphezulu kunye nokuhlwa. I-piezoresistive / capacitance sensors ene-zirconia okanye i-alumina ye-ceramic membrane idla ngokusetyenziswa kumacandelo ekhemikhali, amayeza, kunye nokutya kunye nesiselo. Kwakhona kubalulekile ukuqaphela ukuba njenge-nonmetal, i-ceramic i-brittle ukwenzela ukuba izinzwa ze-ceramic azifanelekanga kwimpembelelo ephezulu, ukutshatyalaliswa kwe-thermal kunye nesicelo soxinzelelo kwaye zifuna ukhathalelo olongezelelweyo ngelixa uphatha.
Ingxubevange yeHastelloy:
I-Hastelloy luluhlu lwee-alloys ezisekelwe kwi-nickel, apho i-C-276 ibonisa ukuxhathisa okufanelekileyo kokutya kwaye idla ngokukhethwa njengesixhobo se-diaphragm yesixhobo kunye nezinye iindawo ezimanzi ngokuchasene neendaba ezibolileyo. I-alloy ye-C-276 isetyenziswa kwiindawo ezininzi zemizi-mveliso apho iimeko zeekhemikhali ezinobundlobongela zibonakaliswe kunye nezinye izinto ezinokusilela.
iStainless Steel 316L:
Olona hlobo luxhaphakileyo lwentsimbi engenastainless lusetyenziswa kwi-diaphragm yokuziva libakala 316L. I-SS316L inokumelana ne-corrosion ephakathi, iipropathi ezifanelekileyo zoomatshini kunye neendleko ezifikelelekayo. Iqokobhe lensimbi engenastainless yezindlu ezingamanziswanga nazo zinokuphucula ukhuseleko kwindawo erhabaxa. Kodwa ukuxhathisa kwayo kwi-corrosion egqithisileyo ilinganiselwe kwaye iyancipha ngeqondo lokushisa eliphakamileyo kunye nokuxinwa okuphakathi kwe-corrosion. Kwimeko enjalo kufuneka kuthathelwe ingqalelo ukutshintsha insimbi engenasici kwindawo emanzi kunye ne-diaphragm kunye nezinye izinto eziphezulu.
IMoneli:
Enye ialloy esekwe nickel ibizwa ngokuba yi-monel. Isinyithi sinamandla ngakumbi kune-nickel ecocekileyo kunye ne-anti-corrosive kwii-asidi ezahlukeneyo kunye namanzi etyuwa. Kwi-offshore naselwandle kusetyenziswa i-monel series alloy idla ngokuba lukhetho oludumileyo lwemathiriyeli ye-diaphragm. Nangona kunjalo, izinto zibiza kakhulu kwaye ngamanye amaxesha zicetyiswa kuphela xa ezinye iindleko eziphantsi zingenakwenzeka kwaye zingafanelekanga kwiimeko ze-oxidizing.
eShanghaiWangYuanngumvelisi onamava wezixhobo zokulinganisa uxinzelelo, inqanaba, ubushushu kunye nokuqukuqela iminyaka engaphezu kwama-20. Iinjineli zethu ezingamagqala ziyakwazi ukuzisa isisombululo esisiso kwimiceli mngeni yazo zonke iintlobo zeemeko zokonakala. Nceda uzive ukhululekile ukuqhakamshelana nathi ukufumana imilinganiselo yeenkcukacha zenkqubo ethile yezicelo.
