Yintoni umphumo wokongeza i-silica powder kwi-concrete?

Ukongeza i-silica powder kwi-concrete kwikhonkrithi kunokuphucula kakhulu amandla ekhonkrithi, ngoko ke ukusetyenziswa kwe-silica fume kwikhonkrithi kuxhaphake kakhulu. Ngokukodwa, zeziphi iingenelo zokongeza i-silica powder kwikhonkrithi?

1. Ikhonkrithi yamandla aphezulu eyenziwe nge-silica fume (ngaphezulu kwe-C70) inokuphucula kakhulu amandla kunye nokumpompa ukusebenza kwekhonkrithi;

2. I-silica powder inomlinganiselo ofanelekileyo wokusabalalisa ubungakanani, ubuninzi obuqinileyo, ubunzima obuphezulu kunye nokumelana nokunxiba okulungileyo, okunokuphucula kakhulu amandla okuqina, amandla oxinzelelo, amandla empembelelo kunye nokumelana nokunxiba kweemveliso eziphilisiweyo, kwaye ukuxhathisa ukunxiba kunokunyuswa nge-0.5- 2.5 amaxesha.

3. I-silica powder inokunyusa ukuhanjiswa kwe-thermal, ukutshintsha ukunamathela kunye nokwandisa i-flame retardant.

4. I-silicon powder inokunciphisa ukushisa kwe-exothermic peak ye-epoxy resin curing reaction, ukunciphisa i-coefficient yokwandisa umgca kunye nesantya sokunciphisa iimveliso eziphilisiweyo, ukwenzela ukuba kupheliswe uxinzelelo lwangaphakathi kunye nokuthintela ukuqhekeka.

5. Ngenxa yobukhulu becala elincinci kunye nokusabalalisa ngokufanelekileyo kwe-silicon powder, inokunciphisa ngokufanelekileyo kwaye isuse imvula kunye ne-stratification;

6. Ipowder ye-silicon inomxholo ophantsi wokungcola kunye neempawu ezizinzileyo zomzimba kunye neekhemikhali, okwenza ukuba umkhiqizo ophilisiweyo ube ne-insulation elungileyo kunye nokumelana ne-arc.

Ukongezwa kwe-silica fume ayinayo kuphela inzuzo engentla, kodwa kunye nokuchasana kweqabaka kunye nomsebenzi kunempembelelo ebaluleke kakhulu ekuphuculeni umgangatho wekhonkrithi.
