Natural rabha. tsananguro

Natural rabha chinhu amorphous muviri, ane mano crystallize. Natural zvinhu (untreated) - Hauoneki kana chichena kabhoni. Natural rabha hakusi soluble doro, mvura, acetone nezvimwe mvura. The mafuta Mahydrocarbon uye aromatics (ethers, benzene, peturu, uye vamwe) nayo wakazara uye urwa zvadaro. Somugumisiro, akaumba colloidal zvinogadzirisa, izvo zvinonzi nevakawanda kushandiswa michina zvinodiwa.

Natural rabha ane yunifomu samolecular marongerwo. The acho ane yakakwirira mumuviri uye kwesayenzi maitiro, nyore nyore chinogadzirwa pamusoro kwakajairika michina.

Natural rabha ane mukuru elasticity (elasticity). The acho anokwanisa kupora kwayo kwepakutanga chimiro kana pasisina kufurira mauto kuti akaita deformation kwayo. Tinofanira kutaura kuti elasticity iri rakaramba mune zvakakwana yakafara tembiricha siyana. Zvisinei, chengetedzo kwenguva refu kunokonzera koukukutu mashoko.

Natural rabha pane kubvisa chimwe namakumi mapfumbamwe namashanu madhigirii yakajeka uye vanachandagwinyira, pagungano tembiricha kuti pakati razero uye gumi madhigirii - opaque uye pfava, pamwe maviri - translucent, kwakavharwa nenyama uye munyoro. Kana neshungu pamusoro 50 ° C mashoko anova epurasitiki uye kunama.

Anorasikirwa kwayo elasticity pana masere madhigirii uye zana madhigirii maviri, ruchapinda muruoko retinoid mvura mamiriro, pashure anoiswa kuti pakutanga chigadzirwa hazviiti. Apo tembiricha inokwira kusvika maviri namakumi mashanu kusvika madhigirii mazana maviri, zvakasikwa rabha anotanga anoora. Zvinoguma nhamba emura uye gaseous zvinhu.

Natural rabha chinhu insulator akanaka. Uyezve, mashoko acho ane pasi gasi uye mvura nemishonga.

Material zvakakwana zvishoma nezvishoma oxidized ne mumhepo okisijeni. Nokukurumidza muitiro kunoitika pasi pokudzora namakemikari oxidants.

Uyewo zvimwe zvivako zvose, rabha ane plasticity. Anokwanisa kuramba chimiro chayo, iyo vawana pasi pokudzora zvimwewo zvinoitika. Plasticity, iyo kunooneka muna machine uye kudziyisa ndechimwe chinosiyanisa zvechadenga zvinhu. Nokuti kuti rabha ane kwakavharwa nenyama uye mapurasitiki zvivako, izvozvo anonziwo plasto-kwakavharwa nenyama zvinhu.

Natural rabha ane nzira - (C5H8) N, kunosanganisira mamorekuru ine vakawanda miviri zvisungo. Material zvikuru nyore zvaanoita pamwe zvinhu zvakawanda. Inosimudzira reactivity nokuda makemikari zvakaita unsaturated zvinhu. Best kudyidzana kunoitika muna avo zvinogadzirisa apo rabha rine mamorekuru ose pfupi guru colloidal inoramba.

Tensile kana kutonhora zviri tama zvinhu kuti crystalline ezvinhu kubva amorphous (crystallization). Izvi zvinoitika mukati imwe nguva, kwete pakarepo. The crystals duku saizi, nokusingagumi geometrical chimiro, uye micheto zvavo damerau.
