Theho tiisa ke ts'ebetso ea 'mele e lebisang ho taba ho tsoa ho boemo ba mokelikeli leha ho le joalo boemo bo tiileng, ka ho fetola maemo a bona a mocheso (Ho hatsela) kapa khatello, kapa ka ho lahleheloa ke mongobo ho mouoane (Tlhaloso). Ke mokhoa o khutlisetsang morao oa kopanya.
Ho tiisa ho feta methating e latelang:
- Boemo ba mokelikeli oa metsi. Likarolo tsa eona li na le matla a mangata 'me li boemong ba ho tsamaea haholo.
- Ponahalo ea li-nuclei tse tiileng ka mokelikeli, joalo ka kristale kapa ho thatafala ha lintho tse mokelikeli.
- Ponahalo ea li-dendrite ka mokelikeli: mela e tiileng e kopanyang li-nuclei le ho bonts'a ponahalo ea li-block tse tiileng kapa tse sekaalo.
- Ponahalo ea lithollo tse tiileng le tahlehelo e latelang ea motsamao oa likaroloana, e lebisang ho tieeng ha mokelikeli.

Mehlala ea ho tiisa
Ho etsa leqhoa. Ka ho tlisa metsi ntlheng ea teng ea leqhoa ea 0 ° C, mokelikeli o lahleheloa ke motsamao oa ona mme o fetoha boemo bo tiileng, ka hona o theha leqhoa ka sebopeho sa setshelo moo metsi a neng a le teng.
Ho etsa likerese. E entsoe ka parafini e nkiloeng ka peterole, li fuoa sebopeho sa tsona 'me khoele e kenngoa ka boka ka mokhoa o batlang o le mokelikeli, ka lebaka la mocheso. Joale, ha e ntse e fola, boka bo thatafala 'me bo lula bo tiile ho fihlela khoele e bonesitsoe, kaha mollo o e khutlisa.
Ho etsa mabenyane. Khauta, silevera le lirafshoa tse ling tsa bohlokoa li sebelisoa ho qhibilihisoa ho etsa mabenyane: mehele, lifaha, jj. Hang ha e se e le mokelikeli, tšepe e lumelloa hore e pholile ka hlobo e itseng, moo e tla tsoa e tiile ebile e hanela.
Ho etsa chokolete. Ho etsa chokolete, ho sebelisoa phofo e fumanoeng ka ho halika le ho sila ea cocoa, e kopantsoe le metsi le lebese ho etsa lehlaka le nang le mokelikeli o mokelikeli o mongata, o ntano folisoa ebe o omisoa ho fumana mefuta e ikhethileng ea khoebo ea eona.
Ho etsa litene. Litene tsa moaho li entsoe ka motsoako oa letsopa le lintho tse ling tseo, ka lekhapetleng le seka-mokelikeli, li fumanang sebopeho sa tsona. Motsoako ona o besoa ho tlosa mongobo ebe o o etsa hore o tiee le ho o hanela.
Ho etsa likhalase. Tlhahiso ea lijana tsa likhalase tsa mefuta eohle e qala ka ho kopanya lintho tse tala (lehlabathe la silica, calcium carbonate le lejoe la mokoetla), ho fihlela e fuoa botsitso bo nepahetseng ho e fehla le ho e bopa, ebe e e pholisa le ho e lumella ho fumana tšobotsi ea eona thatafala le ponaletso.
Ho etsa lisebelisoa. Ho tsoa tšepe ea mokelikeli (alloy ea tšepe le khabone), lisebelisoa le lisebelisoa tse fapaneng bakeng sa ts'ebeliso ea letsatsi le letsatsi li etsoa, tseo ho hanela litšusumetso, khatello le mocheso ho leng bohlokoa, hobane fusion ea tšepe e etsahala maemong a phahameng haholo (ho potoloha 1535 ° C), hangata e ka fihlelleha kantle ho sebopi sa indasteri. Tšepe ea mokelikeli e lumelloa ho pholile le ho tiea ka hlobo 'me sesebelisoa se fumanoa.
Ho itokisetsa Gelatin. Le ha e le colloid (semisolid), e fumanoeng ka ho emisoa ha collagen ho fafatseng le ho nyolla ha lisele tse kopaneng tsa tlhaho ea liphoofolo, ke mohlala oa ho tiisa ka ho lahleheloa ke mocheso o bohlokoa ho etsa motsoako oa metsi.
Tlhahiso ea Latex. Latex ke tharollo ea colloidal ea mafura, boka ba linotši le li-resin tsa semela sa meroho, le lintho tse reketiloeng ka ho fetisisa tse tsejoang. Tlhahiso ea eona bakeng sa liatlana kapa likhohlopo e qala ka pokello ea ntho le kalafo ea eona ea lik'hemik'hale ho e boloka e le metsi, ho aena ha eona kamora moo le tlhahiso ea likarolo tse tšesaane haholo tsa ntho eo, joale, e lumelloang ho oma le ho tiea.
Boimana ba majoe a iphaphathileng. The majne a majoe Li simolohile ho magma e foqohang seretse se chesang e lulang karolong e tebileng ea lefatše, eo e reng ha e mela holimo e phole, e tiee le ho thatafala, ho fihlela e fetoha lejoe.
Ho etsa lipompong. Lipompong tsena li simolohile ho cheleng le ho qhibiliheng ha tsoekere e tloaelehileng, ho fihlela ho fumana ntho e metsi e sootho eo hang ha e tšeloa ka hlobo e ka lumelloang ho thatafala ho etsa caramel.
Motsoako oa lehloa oa hatsela. Tlase ho 45 ° C, mercury, eo hape e tsejoang e le mokelikeli oa silevera, ea tiea, eo boteng ba eona ka mocheso oa kamore hangata e leng mokelikeli.
Moetso o entsoeng ka matsoho oa letsopa. Letsopa ke mofuta oa mobu oo, ha o nosetsoa ka metsi, o bang bonolo ho o nolofaletsa ho etsa lipitsa, lipalo le lijana tsa mesebetsi ea matsoho. Ha letsopa le se le felile, lea thatafala ebe lea tiea, 'me le fetoha ntho e loantšang.
Ho etsa lisoseje tsa mali. Joalo ka lisoseje tse ling, boroso ea mali e entsoe ka mali a kopaneng le a marinated, a phekoloa kahare ho letlalo la letlalo la kolobe. Ha e kopana, mali a metsi a fetoha nama e tiileng ea boroso ea mali.
Ho etsa botorokapa majarine. E 'ngoe ea lits'ebetso tsa indasteri ea tlhahiso ea lijo tsena e na le ho tlotsoa ha oli ea meroho kapa ea liphoofolo, ke hore, hyperhydrogenation ea eona, ho qobella maqhama a le mong ho ba litlamo tse habeli. Ka ts'ebetso ena, oli e ba e tiileng kapa ea colloid (joalo ka botoro) mochesong oa kamore.
Bona hape:
- Mehlala e tsoang ho Liquid ho ea ho Solids (le ka tsela e ngoe ho potoloha)
- Mehlala e tsoang ho Liquid ho ea ho likhase (le tsela e ngoe e potileng)
- Ho tiisa, Fusion, Mouoane ke eng, Sublimation le Condensation ke eng?
