Umenzi weCalcium FormateI-Aojin Chemical yabelana nawe ngendlela esetyenziswa ngayo i-calcium formate kwishishini lesamente yokwakha. I-calcium formate ethengiswa yi-Aojin Chemical inomxholo ophezulu we-98% kwaye ipakishwe kwi-25kg/ingxowa.
Umenzi we-calcium formate i-Aojin Chemical wabelana ngezicelo zakhe kwishishini lesamente yokwakha. I-Aojin Chemical ithengisa i-calcium formate enomxholo ophezulu we-98%, epakishwe kwiingxowa ze-25kg.
I-Calcium formate (Ca(HCOO)₂), i-arhente enamandla kakhulu ye-organic early-strength, isetyenziswa ekuveliseni iimveliso zekhonkrithi nesamente ngenxa yeempawu zayo ezikhethekileyo zeekhemikhali. Imisebenzi yayo ephambili kunye nokusetyenziswa kwayo zezi zilandelayo:
1. Amandla okuqala kunye nokukhawuleziswa kokubeka
I-calcium formate ikhawulezisa kakhulu ukufunxwa kwesamente, ngakumbi ukufunxwa kwe-triccalcium silicate (C₃S) kunye ne-triccalcium aluminate (C₃A). Oku kukhawulezisa ukwakheka kunye nokubekwa kweemveliso zokufunxwa (ezifana ne-ettringite kunye ne-calcium hydroxide), ngaloo ndlela kuphucula amandla okuqala ezinto ezisekwe kwisamente (amandla anokunyuka ngama-20%-50% kwiintsuku ezi-1-7). Le propati iyenza ifaneleke ngokukodwa kulwakhiwo oluphantsi kobushushu (njengokugalelwa ebusika) okanye iiprojekthi zokulungisa ezingxamisekileyo, inciphisa ixesha lokufunxwa kunye nokuqinisekisa ukuba ikhonkrithi iyaqina ngokuqhelekileyo kwiindawo ezinobushushu obuphantsi, ngaloo ndlela ithintela umonakalo wokuqandisa.
2. Ukuphuculwa Kokusebenza Kwekhonkrithi Nokuqina Kwayo
Kwi-samente paste, i-calcium formate inciphisa ukopha kunye nokwahlukana, iphucula ukulingana kunye noxinano lwekhonkrithi. Ngaphezu koko, iimveliso zayo zokufunxa amanzi zizalisa iimbobo zekhonkrithi, zinciphisa ukubola, ziphucula ngokungathanga ngqo ukungangenwa kwekhonkrithi, ukumelana neqabaka, kunye nokumelana nokugqwala, ngaloo ndlela zandisa ubomi benkonzo yeemveliso zekhonkrithi.
3. Ifanelekile kwiintlobo ngeentlobo zezicelo zemveliso yesamente
Kwimveliso yezinto ezilungiselelwe kwangaphambili, ezifana neepaneli ezilungiselelwe kwangaphambili kunye neepayipu, i-calcium formate ikhawulezisa ukujika kwesikhunta, inciphisa ixesha lokunciphisa, kwaye iphucula ukusebenza kakuhle kwemveliso.
I-Shotcrete: Isetyenziswa kwimisebenzi yokutshiza kwiitonela, kwimigodi, nakwezinye iiprojekthi, iqina ngokukhawuleza kwaye iqine, inciphisa ilahleko yokubuyela umva kwaye iphucula ukusebenza kakuhle kolwakhiwo.
Izinto zodaka kunye nodaka: Ziphucula ukugcinwa kwamanzi kunye nokuqina kwangethuba kodaka, ziqinisekisa inkqubela phambili ngokukhawuleza kwiinkqubo zodaka kunye nodaka.
4. Iingenelo zokusingqongileyo kunye nokuhambelana
Ixabiso leCalciumAyinatyhefu kwaye ayicaphukisi, kwaye iyahambelana nesamente, izinto ezinciphisa amanzi, uthuthu lweempukane, kunye nezinye izinto ezixutyiweyo. Ayibangeli iingxaki ezifana nokusabela kwe-alkali-aggregate kwikhonkrithi, ihlangabezana neemfuno zophuhliso lwezinto zokwakha eziluhlaza. Qaphela: Umthamo we-calcium formate kufuneka ulawulwe ngokungqongqo (ngesiqhelo yi-1%-3% yobunzima besamente). Ukongezwa okugqithisileyo kunokucothisa ukukhula kwamandla ekhonkrithi kamva kwaye kubangele nokuqhekeka kokuncipha. Uhlengahlengiso kufuneka lwenziwe ngokusekelwe kwizinto ezifana nendawo yeprojekthi kunye nohlobo lwesamente.
