Cruntils akakosha zvikamu zvemidziyo yemakemikari uye anoshanda semidziyo yekunyungudika uye kunatsa simbi zvinwiwa, pamwe nekudziya uye kuita midziyo yakasimba-yemvura. Ivo vanoumba hwaro hwekuti uve nechokwadi chemakemikari emakemikari.
Crachbles inogona kukamurwa kuita zvikamu zvitatu zvikuru:Graphite Crcudues, clay crunobles, uye simbi inokweretwa.
Graphite cripments inonyanya kugadzirwa kubva kune yakasikwa crystalline graphrahrafiti, inochengetedza akasiyana-siyana emuviri uye makemikari zvivakwa zvegirazi rechisikigo. Ivo vane yakanaka yekudhura kubatana uye yakanyanya kupisa kupisa. Munguva yekunyanyisa kushanduka-tembiricha, ivo vanoratidzira yakaderera yekuwedzera yekuwedzera yekuwedzera, vachiita kuti varambe nekukurumidza kupisa uye kutonhora. Graphite craucties ine yakasimba corrosion kuramba kune acidic uye alkaline mhinduro uye ratidza kusimba kwakanaka kwemakemikari.
Nekuda kwehunhu hwepamusoro hune hunhu, graphite cripments zvinoshandiswa zvakanyanya mumaindasitiri akadai sekugadzika, kukanda, nemichina, uye makemani enjimu. Ivo vanowana kunyoreswa kwakakura mukunyungudika kweiyo Alloy Tool mesera uye kunyungudika kwemasumbu asiri-ferrous, kupa zvakanaka nehunyanzvi uye hupfumi hwakanaka uye hupfumi.
Silicon Carbide Croctibles:
Silicon Carbide Crubless itsvina-yakaumbwa ceramic midziyo. Kana solids inoda kuiswa kupisa pakupisa kwakakwirira, mishonga inodikanwa nekuti inogona kutsungirira tembiricha yakakwirira ichienzaniswa negirazi. Crachblbiles kazhinji isingazikamwi pakushandisa pakushandiswa nekudzivirira zvinhu zvakashata kubva mukupaza, kubvumira mweya kusunungura uye kufambisa oxidation maitiro. Nekuda kweshoma yavo diki, cruncuducs inowanzoiswa pane clay triangle yekudziya zvakananga. Ivo vanogona kuve vakamira vakarurama kana pakona pane iron tripod, zvichienderana nezvinodiwa zvekuedza. Mushure mekupenga, crazics haifanirwe kuiswa pakarepo pane inotonhora yesimbi pamusoro kuti udzivise kukurumidza kutonhora uye kugona kuputsa. Saizvozvo, ivo havafanirwe kuiswa zvakananga pane yemapuranga pamusoro pekudzivirira kupisa kana njodzi dzemoto. Maitiro echokwadi ndewekubvumidza iyo crcuducs kuti itonhore pachisikigo pane iron tripod kana vaise pane asbestos net yekudzora zvishoma nezvishoma. Hungu dzinochinjika dzinofanira kushandiswa kubata.
Platinamu Cratobles:
Platinamu cratinbles, yakagadzirwa nesimbi platinum, shanda seyekuti zvimiti zvekusiyanisa zviongorori zvekushandisa uye zvinoshandiswa kupisa zvinhu zvisina mesimbi, senge girazi fiber kugadzirwa uye girazi rekugadzira.
Havafanirwe kusangana ne:
Solid Compound yakadai se K2O, NA2O, Kno3, nano3, kcn, nacn, na2o2, ba (o) 2, lioh, etc.
Aqua Regia, mhinduro dzeHloagen, kana mhinduro dzinogona kuburitsa halgens.
Makomputa ekudzora mashoma mashoma nesimbi uye simbi ivo pachavo.
Kabhoni-ine sizi, phosphorus, arsenic, sarufa, uye makomendi avo.
Nickel Croclibles:
Iyo yekunyungudutsa nzvimbo yeNickel ndeye 1455 degrees Celsius, uye tembiricha yemuenzaniso mune nickel inowanzoitika haifanirwe kupfuura mazana manomwe emadhigirii ekudzivirira oxidation pakudziya kwakanyanya.
Nickel crculibles inodzivirira zvakanyanya kuAlkaline zvinhu uye kuora, kuita kuti vakwanise kunyungudutsa allet simbi alloys, slag, clay, nzvimbo dzekunongedza, uye zvimwe. Nickel crcuducs inoenderana neAlkaline fluxes yakadai sa naOoh, na2o2, naiyo vane kno4, nahso4, k2s2o7 uye sulfide fluxes nesarufa nesarufa nesarufa. Kunyungudutsa munyu waAluminium, zinc, kutungamira, tin, uye mercury inogona kupa nickel cropclibles brittle. Nickel crcudubles haifanirwe kushandiswa kune inopisa madziri, uye borax haifanire kunyungudika mavari.
Nickel crculibles inowanzove neye trace huwandu hwechromium, saka kungwara kunofanirwa kuve kwakadzvanywa kana, chikamu chakamiswa.
