Baphucula iimpawu ezibonakalayo kunye neekhemikhali zekhonkrithi ngokuzisa iipolymers, ngaloo ndlela ziphucula amandla, ukuqina, ukusebenza, njl njl. Izongezo zePolymer zinokwahlulwa zibe ziindidi ezininzi, kubandakanywa iipolima ezinyibilikayo emanzini, iipolymers ze-emulsion, iipolima zomgubo, kunye neepolima ezisebenzayo.
Iintlobo zezongezo zepolymer
Iipolima ezinyibilikayo zamanzi: Ezi polymers zidla ngokubakho ngendlela yezisombululo ezinamanzi, ikakhulu zibandakanya i-polyvinyl alcohol (PVA), i-polyacrylamide (PAM), njl njl. ukunganyanzeki kunye nokumelana nokuqhekeka kwekhonkrithi.
Iipolymers ze-emulsion: Iipolymers ze-emulsion luhlobo lweepolymers ezenziwe nge-emulsion polymerization, kwaye eziqhelekileyo ziquka i-styrene-acrylate copolymers kunye ne-ethylene-vinyl acetate copolymers. Olu hlobo lwepolymer lunokuphucula iimpawu zokubambisana zekhonkrithi kunye nokwandisa ukuqina kunye nokuxhatshazwa kwe-crack yekhonkrithi.
Iipolymers zomgubo: Iipolymers ezinomgubo zingongezwa ngokuthe ngqo kwimixube eyomileyo, efana ne-ethylene-vinyl acetate powder (EVA), i-acrylate powder, njl njl. kunye nokuqhekeka kwekhonkrithi.
Iipolima ezisebenzayo: Ezi polymers zinokusabela ngokwekhemikhali kunye namacandelo esamente ukwenza into edibeneyo edibeneyo kunye neyomelele ngakumbi. Ngokomzekelo, i-epoxy resins, i-polyurethanes, njl., inokuphucula kakhulu ukuxhatshazwa kweekhemikhali, ukunyanzeliswa kwe-permeability kunye nokumelana nokunxiba kwekhonkrithi.
Indlela yokusebenza yezongezo zepolymer
Izongezo zePolymer ziphucula ukusebenza kwekhonkrithi ngeziphumo zomzimba kunye neekhemikhali. Umphumo womzimba ngokuyinhloko ukugcwalisa ii-pores kwi-sement paste, ukwandisa ubuninzi bekhonkrithi, kunye nokunciphisa ukunyanzeliswa kwamanzi. Impembelelo yeekhemikhali kukwenza i-elastic composite material ngokusebenzisa intsebenziswano phakathi kwepolymer kunye neemveliso ze-cement hydration, ngaloo ndlela kuphuculwe ukuqina kunye nokuqina kwekhonkrithi.
Ukuphucula ukusebenza kwe-bonding: Izongezo ze-polymer zingenza ifilimu phakathi kwamaqhekeza e-samente kunye nee-aggregates, ukuphucula ukudibanisa phakathi kwezi zibini, kwaye ngaloo ndlela kukhulise amandla kunye nokuchasana kwekhonkrithi.
Ukunciphisa i-shrinkage cracking: Ezinye iipolymers zinokunyusa ukuguquguquka kunye ne-ductility yekhonkrithi, ukunciphisa ukuqhekeka okubangelwa yi-shrinkage, kwaye ngaloo ndlela ukwandisa ubomi benkonzo yezakhiwo eziphathekayo.
Ukuxhathisa kwi-Chemical corrosion: izongezo zepolymer zinokuphucula ukuxhathisa kwikhemikhali ye-corrosion, ngakumbi kwiindawo ezinobungozi ezifana ne-asidi, i-alkali kunye netyuwa. Ezi polymers zinokuthintela ngokufanelekileyo ukungeniswa kweendaba ezitshabalalisayo kunye nokukhusela izakhiwo zekhonkrithi.
Phucula ukumelana nokunyibilika komkhenkce: Kwiindawo ezibandayo, ikhonkrithi ihlala yonakaliswa yimijikelo yokunyibilika komkhenkce. Izongezo zePolymer zinokuphucula ngokufanelekileyo ukuxhathisa ukunyibilika komkhenkce kwekhonkrithi ngokuphucula ukuxinana kunye nokumelana nokuqhekeka.
