Uyini umehluko phakathi kwamagwebu amabili ensimbi, igwebu lethusi negwebu le-nickel?

1. Izici nezinzuzo ze-foam yethusi

Okokuqala, ake sibheke inqubo yokukhiqiza kanye nezici zethusi elinegwebu; esakhiweni sethusi esinegwebu, ithusi lisetshenziswa ikakhulukazi njenge-substrate, futhi inqwaba yemigodi isakazwa ngokulinganayo ku-substrate yethusi ngesikhathi sokukhiqiza. Uma kuqhathaniswa negwebu le-nickel, igwebu lethusi liphansi ezindlekweni zokukhiqiza; ngesikhathi esifanayo, i-foam yethusi nayo ine-conductivity kagesi engcono kanye ne-ductility.

2. Inkambu yesicelo se-foam yethusi

Igwebu le-Copper ngokwayo line-conductivity kagesi enhle kakhulu ngoba ithusi lisetshenziswa njenge-substrate; ngakho-ke, i-foam yethusi ingasetshenziswa njengento engaphansi kwe-electrode yebhethri. Uma kuqhathaniswa nethusi elinegwebu, igwebu le-nickel linezinzuzo eziningi ekumunceni umsindo. I-foam yethusi ine-ductility enhle kakhulu nokusebenza kokucubungula, futhi ingaqhuba ukushisa futhi iqhube ugesi; futhi ingaphakathi lethusi eliyigwebu liyisakhiwo esinezimbotshana ezinezinhlangothi ezintathu ezinezinhlangothi ezintathu, esinakho kokubili isivikelo sikagesi, ukuncishiswa komsindo nokumuncwa ukushaqeka, futhi imelana kakhulu ne-alkali futhi imelana nokugqwala. Ngakho-ke, ekushiseni kokushisa kanye namadivayisi okushintshanisa ukushisa kwe-CPU, ikhadi lehluzo, namadivayisi kagesi, i-foam yethusi isetshenziswa kakhulu; ngaphezu kwalokho, ngenxa yokuthi i-foam yethusi ine-conductivity enhle kakhulu, ivame ukusetshenziswa njengento ye-electrode ye-lithium electronics noma ama-fuel cell; Ingasetshenziswa njengezinto zokuvikela ugesi, izinto zokwakha, izinto ezimunca umsindo, njll., futhi inohlu olubanzi kakhulu lwezinhlelo zokusebenza nezinkambu.

3. Izinkambu zokufaka isicelo zegwebu le-nickel

Igwebu le-nickel livame ukusetshenziswa njengento ebamba umsindo futhi lisetshenziswa ekudaleni izinto zokuhlukanisa. I-nickel foam ngokwayo nayo inezinzuzo eziningi, ayinayo kuphela isakhiwo esiyingqayizivele se-open-cell, kodwa futhi ine-tensile enhle kakhulu, ukushisa nokumelana nomthelela, ngakho-ke ibuye isetshenziswe kabanzi njenge-catalyst ye-organic chemical reaction nokunye. Njengamanje, uma kuqhathaniswa nensimbi ekwazi ukumelana nokushisa okuphezulu kanye nesithwali se-ejenti yamakhemikhali e-ceramic, i-nickel catalyst enegwebu isebenza kangcono ngomqondo othile; ibuye isetshenziswe kabanzi ekuphenduleni kwe-Fischer-Topsch, i-gas Hydrogenation reaction foam catalyst catalyst carrier yamakhemikhali aguquliwe, e-boutique.
