Natural rabara. tlhaloso

Natural rabara ke 'mele amorphous, le bokhoni ba ho crystallize. Natural lintho tse bonahalang (untreated) - colorless kapa o mosoeu k'habone. Natural rabara ha se qhibilihang ka har'a joala, metsi, monohalogen acetone le sephalli tse ling. Tse mafura hydrocarbons le aromatics (ethers, benzene, peterole, le tse ling) ho swells le qhalana hamorao. Ka lebaka leo, ha thehoa ditharollo colloidal, tse sebelisoang haholo ka litlhoko tsa botekgeniki.

Natural rabara na junifomo sebopeho ea limolek'hule. lintho tse bonahalang o na le e phahameng le litšobotsi tse 'meleng le theknoloji, hang-hang e sebetswa ka thepa tloaelehileng.

Natural rabara o phahameng elasticity (elasticity). lintho tse bonahalang tse ke khona ho hlaphoheloa sebopeho ka eona qalong ha e ha e sa susumetsa makhotla a e bakileng deformation lona. Re lokela ho re elasticity e bolokoa ka ho lekaneng lohle mocheso telele. Leha ho le joalo, poloko ea nako e telele ho etsa hore a thatafatsa ba boitsebiso boo.

Natural rabara ka ho tloswa e mong lekholo mashome a robong tse hlano likhato sebeletsang pepeneneng le thata, ka mocheso oa pakeng lefela le leshome likhato - opaque le brittle, ka mashome a mabeli - translucent, rekere le bonolo. Ha halefile ka hodimo 50 ° C lintho tse bonahalang tse tla ba polasetiki le theipi.

Lahleheloang elasticity lona e ka ba likhato tse mashome a robeli le lekholo le likhato tse mashome a mabeli, e tsoela ka retinoid boemo mokelikeli, ka mor'a ho beha ho fumana sehlahisoa pele etsahala. Ha mocheso o phahama ho fihlela ho makholo a mabeli mashome a mahlano ho likhato tse makholo a mabeli, rabara tsa tlhaho qala ho bola. Phello ke a 'maloa a dintho mokelikeli le gaseous.

Natural rabara ke kobo e molemo. Ho feta moo, lintho tse bonahalang o na le e tlase khase le metsi ho hanyetsa.

Lintho tse bonahalang ka ho lekaneng butle oxidized ke oksijene sepakapakeng. Kapele thulaganyou e etsahala tlas'a tšusumetso ea oxidants lik'hemik'hale.

Hape thepa tse ling kaofela, rabara na plasticity. O khona ho ba boloke sebopeho lona, e neng e e fumanweng tlas'a tšusumetso ea lintlha kantle. Plasticity, e bontša ka machining le futhumatsang ke e 'ngoe ea litšobotsi tse khethollang ba boitsebiso boo. Ka lebaka la 'nete ea hore rabara o na le rekere le polasetiki thepa, ho o boetse o bitsoa ka plasto-rekere lintho tse bonahalang.

Natural rabara eo moralo - (C5H8) n g, ho akarelletsa ho limolek'hule tse nang le palo e kholo ea litlamo habeli. Lintho tse bonahalang habonolo haholo a leka ka dintho tse ngata. Eketseha reactivity ka lebaka la ho sebopeho lik'hemik'hale tsa lintho tse bonahalang tse unsaturated. Libaka tse Hloahloa tsa sebelisana le hlaha ka ditharollo ba eo rabara e na le limolek'hule tsa likaroloana batlang e le kholo colloidal.

Tensile kapa tsidifatso e fetisetsa boitsebiso bo bongata ho boemo bonaletsang tswa amorphous (crystallization). Tšebetso ena e etsahala ka nako e itseng, e seng hang-hang. kristale ka ba le boholo ba tse nyenyane, tse sa lekanyetsoang tsa thutatekanyo sebopeho, le molekeng oa lerotho bona.
