Iikhemikhali eziyingozi zibhekisa kwiikhemikhali eziyityhefu kakhulu kunye nezinye iikhemikhali eziyityhefu, ezitshabalalisayo, ezidubulayo, ezinokutsha, ezixhasa ukutsha neziyingozi kumzimba womntu, kwizibonelelo nakwindalo esingqongileyo.
Ii-agent eziphezulu zokunciphisa amanzi kwiikhonkrithi zibandakanya uchungechunge lwe-naphthalene, uchungechunge lwe-melamine kunye nee-agent zokunciphisa amanzi ezixutywe kuzo, apho uchungechunge lwe-naphthalene luphambili, lubalelwa kwi-67%.Uchungechunge lweNaphthalene kunye nochungechunge lwe-melamine azikho iikhemikhali ezinobungozi.Ke ngoko, i-superplasticizer yekhonkrithi ayiyonxalenye yodidi lweekhemikhali eziyingozi.
I-admixture enokunciphisa kakhulu umthamo wamanzi okuxuba phantsi kwemeko yokuba i-slump yekhonkrithi ngokusisiseko iyafana ibizwa ngokuba yi-agent ephezulu yokunciphisa amanzi.
Izinga lokunciphisa amanzi kwi-agent ephezulu yokunciphisa amanzi inokufikelela ngaphezu kwe-20%.Ikakhulu iqulunqwe uchungechunge lwe-naphthalene, uchungechunge lwe-melamine kunye nee-agent zokunciphisa amanzi ezixutywe kuzo, apho uchungechunge lwe-naphthalene luphambili, lubalelwa kwi-67%.Ngokukodwa e-China, uninzi lwe-superplasticizers luchungechunge lwe-naphthalene superplasticizers kunye ne-naphthalene njengeyona nto iphambili ekrwada.I-superplasticizer ye-series ye-Naphthalene inokwahlulwa ibe yimveliso yoxinaniso oluphezulu (umxholo we-Na2SO4 <3%), iimveliso zoxinaniso oluphakathi (umxholo we-Na2SO4 3% ~ 10%) kunye neemveliso zoxinzelelo oluphantsi (umxholo we-Na2SO4> 10%) ngokuhambelana nomxholo we-Na2SO4 kwiimveliso zayo. .Uninzi lwezityalo ze-naphthalene ze-superplasticizer synthesis ziyakwazi ukulawula umxholo we-Na2SO4 ngaphantsi kwe-3%, kwaye amanye amashishini aphezulu angakwazi ukuyilawula ngaphantsi kwe-0.4%.
Ubungakanani besicelo:
Isebenza kwi-precast kunye ne-cast-in-place yekhonkrithi eyomeleziweyo kwizakhiwo ezahlukeneyo zemizi-mveliso kunye nezoluntu, ukugcinwa kwamanzi, ukuthutha, amazibuko, umasipala kunye nezinye iiprojekthi.
Isebenza kumandla aphezulu, i-ultra-high-strength kunye ne-medium-strength-concrete, kunye nekhonkrithi efuna amandla okuqala, ukuchasana kweqabaka kunye nokunyuka kwamanzi amaninzi.
Amacandelo ekhonkrithi asele enziwe alungele inkqubo yokunyanga umphunga.
Ifanelekile ukwenza amacandelo okunciphisa amanzi kunye nokuqinisa (okt masterbatch) yee-admixtures ezahlukeneyo ezidibeneyo.
Ayingowe.Iikhemikhali ezinobungozi zizinto eziqhumayo.Nangona kunjalo, i-superplasticizer yekhonkrithi jikelele ayinazo izinto eziqhumayo neziqhumayo, ngoko ke i-concrete ye-concrete ye-concrete ayiyoyemichiza eyingozi.
