Mitsipa ane kukokwa kwakakosha: zviso zvavo zvepanyama zvinoratidzirwa nejeriyamu yakasimba, iyo inowanzowanzova yezvinhu zvakave nokugadzirwa kwekwenyanzvi.
Kuti uite chinhu chakanakisisa iwe pachako iwe unofanirwa kuziva kukura kristini, uye kuratidza kushivirira zvishomanana. Zvakanaka kana ukawedzera vana pakukura kwemakristasi, izvo izvo zvinoratidzika sezviri chaizvo magic. Urefu hwekristini hwakanyatsoenderana nenguva inotora kukura. Kana chirongwa che crystallization chinonoka, kristini imwechete yakakura yakaenzana yakaumbwa, kana nokukurumidza - makristasi maduku anowanikwa.

Nzira dzekukura makristasi
Kune nzira dzakawanda dzekukura makristst.
Kuchengetedza kwakazara nzira
Iyi nzira inobva pamutemo wemuviri, unotaura kuti kusagadzikana kwezvinhu kunoderera kana kutonhora kunoderedzwa. Kubva pane sediment yakaumbwa panguva yekuparara kwechinhu chacho, kutanga kuoneka makriststal maduku, zvishoma nezvishoma kuchinja kuva makriststals anogara achigadzirwa.
Yakapera evaporation yemvura kubva muganhu
Iyo yakagadziriswa ine sarudzo yakazara yakasara yakazaruka kwenguva refu. Inofanira kufukidzwa nemapepa, kuitira kuti kubuda kwemvura kuoneke zvishoma nezvishoma, uye mhinduro yacho inodzivirirwa kubva muguruva. Zviri nani kutengesa kristini pamutsara. Kana yakarara pasi, ipapo krisstal inokura inofanira kushandurwa nguva nenguva. Sezvo mvura ichidzikira zvishoma nezvishoma, sarudzo yakazara inowedzerwa sezvinodiwa.
Chii chinogona kukura kubva kuCriststal?
Zvinokwanisika kukura makristuru kubva kune zvakasiyana-siyana zvinhu: shuga, kubika soda, sodium bicarbonate. Mumwe munyu (mupfungwa yemakemikari inowanikwa), pamwe nemamwe marudzi e-organic acids, achaenderana zvakakwana.
Kukurira makristasi kubva munyu
Tafura yemunyu chinhu chinowanikwa mune chero musha. Kuti ikure kubhenekeri kwayo yakajeka, inofanirwa kugadzirira kushanda sarudzo. 200 ml yemvura mubhegi yegirazi (chirongo) inowanikwa mundiro nemvura + 50 ... + 60 degrees. Girazi inodurura munyu, inosanganiswa uye inopera zvishoma.
Pasi pesimba remhepo, munyu unopera. Ipapo munyu unowedzerwa zvakare uye unosanganiswa zvakare. Nzira yacho inodzokororwa kusvikira munyu usiri kupera uye unotanga kugadzikana kusvika pasi. Shanduro ya supersaturated inodururirwa mumudziyo wakachena, wakaenzana nehuwandu, asi masara emunyu anobviswa kubva pasi. Kusarudza kristol yakakura, tiisungire kumucheka worembedze kuitira kuti irege kugunzva masvingo egiyo, kana kuipararira kusvika pasi.
Mushure memazuva mashomanana, kuchinja kwekristol kunoonekwa. Iyo nzira yekukura inogona kupedzisa chero bedzi kisi yekristini isingakufanani newe.
Kuti uite marara emakristani, unogona kushandisa mavara ezvokudya.
Kukura kwemakristani kubva mumhangura sulfate
Saizvozvowo inokura mabhuruu-ruvara rwemavara emhangura sulfate.
Chinhu chinogadziriswa chinogadziriswawo zvakare umo kristalo yemhangura sulphate munyu inoiswa. Asi sezvo ichi chinhu chakakonzerwa nemakemikari, zviri nani kushandisa mvura yakasvibiswa.
Nzira yekukura kristini kubva ku soda?
Magirazi maviri azere nemvura inopisa, mune imwe neimwe inodururwa zvimedu zvishomanana zvekubheka soda kusvikira yarega kuparara (a precipitate inoumbwa). A saucer inoiswa pakati pegirazi. Chidimbu chetambo rakakoshwa rinowanikwa kune pepa pepa. Rimwe chinyorwa chinonamatira kumadziro egirazi imwe, yechipiri kune imwe. Mhedziso dzetambo dzinofanira kunge dziri mugadziriswa, uye tsvimbo pachayo inofanira kuputika pasina kugunzva saucer. Kuti makristasi akure zvakanaka, zvinokosha kudira sarudzo se evaporation.
Iye zvino pane makiti ekukura makristasi. Pakuvirisa kwemakemikari, munhu anogona kuwana zvisiri zvisiri zvemakrismatic uye acicular makristasi.
Uyewo nevana, unogona kuedza kuongorora kwakasiyana siyana nemvura kana kuedza kuita mvura inopenya .
