Chii chinangwa chikuru chendarira chena?Chingasiyaniswa sei nesirivha?

Isu tinoshandisa simbi zhinji muhupenyu hwedu, uye kune simbi mune dzakasiyana zvigadzirwa.Mhangura chenaicopper-based alloy ine nickel sechinhu chikuru chakawedzerwa.Ichena-chena uye ine simbi inopenya, saka inonzi cupronickel.Mhangura uye nickel inogona kunyungudika kusingaperi mune imwe neimwe, nokudaro ichigadzira inoenderera yakasimba mhinduro, ndiko kuti, zvisinei nereshiyo yeumwe neumwe, inogara iri α-single-phase alloy.Kana nickel yakanyungudutswa mumhangura tsvuku uye zvirimo zvichipfuura 16%, ruvara rwechigadzirwa chinobuda chinova chena sesirivha.Iyo yakakwira nickel yemukati, iyo ichena ruvara.Iyo nickel yemukati mu cupronickel inowanzo 25%.

1. Kunyanya kushandiswa kwe cupronickel
Pakati pemhangura alloys, cupronickel inoshandiswa zvakanyanya mukuvaka ngarava, petroleum, indasitiri yemakemikari, kuvaka, magetsi emagetsi, chaiyo chiridzwa, midziyo yekurapa, kugadzirwa kwezviridzwa zvemimhanzi uye mamwe masekisheni sezvimiro zvinodzivirira corrosion nekuda kwekushomeka kwayo kwakanakisa uye kuumba nyore, kugadzirisa uye kuputika..Imwe cupronickel inewo yakakosha magetsi emagetsi, ayo anogona kushandiswa kugadzira resistive zvinhu, thermocouple zvinhu uye waya dzekuripa.Isiri-industrial cupronickel inonyanya kushandiswa kugadzira zvigadzirwa zvemaoko.
Chechipiri, siyanisa pakati pendarira chena nesirivha
Nokuti zvishongo zvemhangura zvichena zvakafanana nezvishongo zvesirivha sterling maererano nemuvara uye basa.Vamwe vatengesi vasina hunhu vanotora mukana wekusanzwisisa kwevatengi zvishongo zvesirivheri uye vanotengesa zvishongo zvekapunickel sezvishongo zvesirivha zvinoyevedza, kuitira kuti vawane mhindu huru kubva mazviri.Saka, sei kusiyanisa sterling sirivheri zvishongo kana chena mhangura zvishongo?
Zvinonzwisiswa kuti general sterling zvishongo zvesirivha zvicharatidzwa nemashoko S925, S990, XX pure sirivheri, nezvimwewo, nepo cupronickel jewelry isina mucherechedzo wakadaro kana mucherechedzo haunyatso kujeka;pamusoro pesirivha inogona kunyorwa netsono;uye kuumbwa kwemhangura kwakaoma uye hakuite Zviri nyore kukwenya mavanga;ruvara rwesirivheri rwakaita yero zvishoma sirivha-chena, imhaka yekuti sirivheri iri nyore kuita oxidize, uye inoratidzika yakasviba yero mushure meiyo oxidation, nepo ruvara rwechena mhangura ichena yakachena, uye makwapa egirinhi anozoonekwa mushure menguva.
Uye zvakare, kana donhwe reyakaomeswa hydrochloric acid rakadonhedzwa mukati mezvishongo zvesirivheri, chena moss-senge precipitate yesirivheri chloride inogadzirwa nekukurumidza, izvo zvisiri izvo ne cupronickel.
Ichi chinyorwa chinozivisa zvakadzama mashandisirwo makuru e cupronickel uye yekuzivikanwa nzira ye cupronickel nesirivheri.Cupronickel inoshandiswa mukuvaka ngarava, peturu, indasitiri yemakemikari, kuvaka, simba remagetsi, zviridzwa zvakaringana, midziyo yekurapa, kugadzirwa kwezviridzwa zvemimhanzi uye mamwe madhipatimendi sezvimiro zvinodzivirira corrosion.Mhangura chena haisi nyore kukweshwa, uye ruvara rwakachena rwakachena, rwakasiyana chaizvo nesirivha.
