1. Iyakwazi ukuncibilika xa ishushu ngaphezu kwe-200 ° C, kwaye umxholo womlotha umalunga ne-0.5% xa utshiswa, kwaye ungathathi hlangothi emva kokwenziwa kwi-slurry ngamanzi. Ngokubhekiselele kwi-viscosity yayo, kuxhomekeke kwinqanaba le-polymerization.
2. Ukunyibilika emanzini kuhambelana ngokungafaniyo nobushushu, ubushushu obuphezulu bunokunyibilika okuphantsi, ubushushu obuphantsi bunonyibiliko oluphezulu.
3. I-soluble kumxube wamanzi kunye ne-organic solvents njenge-methanol, i-ethanol, i-ethylene glycol, i-glycerin kunye ne-acetone.
4. Xa ityuwa yesinyithi okanye i-electrolyte ye-organic ikhona kwisisombululo sayo samanzi, isisombululo sisenokuhlala sizinzile. Xa i-electrolyte yongezwa kwisixa esikhulu, i-gel okanye imvula iya kubonakala.
5. Umsebenzi womphezulu. Iimolekyuli zayo ziqulethe amaqela e-hydrophilic kunye namaqela e-hydrophobic, ane-emulsification, ukukhuselwa kwe-colloid kunye nokuzinza kwesigaba.
6. I-Gelation ye-Thermal. Xa isisombululo se-aqueous sinyuka kwiqondo lokushisa elithile (ngaphezu kweqondo lokushisa le-gel), liya kuba namafu kude kube yi-gel okanye i-precipitate, okwenza isisombululo silahlekelwe yi-viscosity yayo, kodwa sinokubuyela kwimeko yaso yokuqala ngokupholisa. Iqondo lokushisa apho i-gelation kunye nemvula eyenzekayo ixhomekeke kuhlobo lwemveliso, ukuxinwa kwesisombululo kunye nesantya sokufudumala.
7. Ixabiso le-pH lizinzile. I-viscosity emanzini ayichatshazelwa lula yi-asidi kunye ne-alkali. Emva kokongeza inani elithile le-alkali, kungakhathaliseki ukuba ukushisa okuphezulu okanye ukushisa okuphantsi, akuyi kubangela ukubola okanye ukuhlukana kwekhonkco.
8. Isisombululo sinokwenza ifilimu ecacileyo, eqinile kunye ne-elastic ebusweni emva kokumisa. Iyakwazi ukumelana nezinyibilikisi eziphilayo, amafutha kunye neeoli ezahlukeneyo. Ayiyi kuba tyheli xa ibonakaliswe ekukhanyeni, kwaye ayiyi kubonakala iintanda ezinoboya. Inokunyibilika emanzini kwakhona. Ukuba i-formaldehyde yongezwa kwisisombululo okanye emva kokuba iphathwe nge-formaldehyde, ifilimu ayinyibiliki emanzini kodwa iyancipha inxalenye.
9. Ukutyeba. Iyakwazi ukujiya amanzi kunye neenkqubo ezingenamanzi, kwaye inokusebenza kakuhle kwe-anti-sag.
10. Ukunyuka kwe-viscosity. Isisombululo saso samanzi sinamandla okubambisana okuqinileyo, okunokuphucula amandla okubambisana kwesamente, i-gypsum, ipende, i-pigment, iphepha lodonga kunye nezinye izinto.
11. Umba onqunyanyisiweyo. Ingasetyenziselwa ukulawula i-coagulation kunye nemvula yamasuntswana aqinileyo.
12. I-colloid yokukhusela ukwandisa ukuzinza kwayo. Inokuthintela ukudityaniswa kunye nokudibana kwamathontsi kunye neepigments, kwaye ithintele ngokufanelekileyo imvula.
