Njengoko ilizwi lisithi, "ingcali ijonge emnyango, i-layman ibheka isihlwele", amandla okuqala e-samente akhula ngokukhawuleza, amandla kamva akhula ngokucothayo, ukuba iqondo lokushisa kunye nokufuma kuyafaneleka, amandla ayo asengakhula ngokucothayo. iminyaka embalwa okanye iminyaka elishumi. Makhe sithethe ngokusetyenziswa kwe icalcium formateukusombulula ingxaki yokumiswa kwesamente kunye nokuqina.
Ixesha lokumisela yenye yezalathisi zentsebenzo ezibalulekileyo zesamente
(1) I-hydration yesamente iqhutyelwa ngokuthe ngcembe ukusuka phezulu ukuya ngaphakathi. Ngokuqhubeka kwexesha, i-hydration degree ye-samente iyanda, kwaye iimveliso ze-hydration nazo ziyanda kwaye zizalise i-capillary pores, eyanciphisa i-porosity ye-capillary pores kwaye ihambelane nokwandisa i-porosity ye-gel pores.
Ifomati yecalcium inokunyusa i-concentration ye-Ca 2 + kwinqanaba le-liquid, isantya sokuchithwa kwe-calcium silicate, kunye ne-co-ionic effect iya kukhawulezisa i-crystallization, yandise umlinganiselo wesigaba esiqinileyo kumdaka, ohambelana nokwakhiwa kwesamente. isakhiwo samatye.
Ukusasazwa kunye ne-viscosity yeicalcium formate kudaka zaphononongwa ngokuhlalutya inkangeleko yayo, ukucoleka, umxholo wefomati kunye nokunyibilika kumanzi abandayo. Iipropati zeemveliso ze-calcium formate kunye namandla ebhondi kudaka lokutyabeka zavavanywa kwaye zathelekiswa.
ubushushu
(2) Ubushushu bunempembelelo ebalulekileyo ekumiseni nasekuqineni kwesamente. Xa izinga lokushisa linyuka, i-hydration reaction ikhawuleza, kwaye amandla e-samente akhula ngokukhawuleza. Xa iqondo lobushushu liyancipha, i-hydration iyancipha kwaye amandla akhula kancinci. Xa ubushushu bungaphantsi kwe-5℃, ukuqina kwe-hydration kuyancipha kakhulu. Xa ubushushu bungaphantsi kwe-0℃, i-hydration reaction ngokusisiseko iyayeka. Ngexesha elifanayo, ngenxa yobushushu obungaphantsi kwe-0° C, xa amanzi engumkhenkce, iya kutshabalalisa isakhiwo samatye e-samente.
Kwiqondo lokushisa eliphantsi, umphumo weicalcium formatekuvakala ngakumbi.Ifomati yecalciumngubushushu obutsha obuphantsi kunye ne-coagulant yokuqala yamandla ephuhliswe e-China, kunye neempawu ezibonakalayo ze icalcium formatezizinzile ngokwentelekiso kwiqondo lobushushu begumbi, akukho lula ukuhlanganisana, zifaneleke ngakumbi ukusetyenziswa kwidaka.
ukufuma
(3) Ilitye le-samente kwindawo efumileyo linokugcina amanzi aneleyo ukuze i-hydration kunye ne-condensation kunye nokuqina, kunye ne-hydration eveliswayo iya kugcwalisa ngakumbi iipores kwaye ikhuthaze amandla elitye le-samente. Amanyathelo okugcina ubushushu kunye nomswakama wendawo, ukwenzela ukuba amandla elitye le-samente aqhubeke ekhula, abizwa ngokuba yisondlo. Xa umisela amandla e-samente, kufuneka uphiliswe kwiminyaka echaziweyo kwiqondo lokushisa eliqhelekileyo kunye nomswakama.
Ifomati yecalciumI-arhente yamandla kwangethuba yi-arhente yamandla ekhonkrithi kwangoko enoluhlu olubanzi lwesicelo kunye nesiphumo esihle. Inani elikhulu lezifundo zovavanyo ziye zabonisa ukuba ukusetyenziswa kwe-calcium formate arhente yamandla kwasekuqaleni kunempembelelo ebalulekileyo ekunciphiseni ixesha lokumisela kunye nokuphucula amandla okuqala ekhonkrithi, kwaye kunokuthintela ngempumelelo umonakalo owenziwe ngumkhenkce wekhonkrithi phantsi kweemeko zobushushu obuphantsi.
