Ukukhethwa kwemixube ekhonkrithi:
(1) I-ejenti yokunciphisa amanzi esebenzayo kunye nephezulu: Ekubeni i-fluidity yekhonkrithi ihlengahlengiswa ikakhulu yi-ejenti ephezulu yokunciphisa amanzi, i-dosage yenza i-1% ukuya kwi-2% yobunzima besamente; kwikhonkrithi eneemfuno ezizodwa zamandla okuqala, sebenzisa i-samente yokumisa ngokukhawuleza okanye Yongeza umsi we-silica; xa usebenzisa umsi we-silica kwikhonkrithi efuna ukuxhathisa ukunxiba, kwaye xa umthamo omkhulu wekhonkrithi enamandla amakhulu kufuneka unciphise ubushushu be-hydration, umthamo wesamente kufuneka uncitshiswe kwaye umsi we-silica okanye uthuthu lwempukane kufuneka zongezwe. Ixesha lokuqala lokumisela ikhonkrithi exutywe kunye ne-agent ephezulu yokunciphisa amanzi ixesha elide kunekhonkrithi eqhelekileyo. Okukhona isixa esikhulu, kokukhona lide ixesha lokuqala lokumisela.
(2) I-ejenti yokungenisa umoya kunye ne-ejenti yokunciphisa amanzi yokungenisa umoya: Kufuneka ukuba ibe nokumelana neqabaka ephezulu kunye noxinano oluphezulu, kwaye kufuneka ixutywe kunye ne-agent-entraining agent okanye i-ejenti yokunciphisa amanzi. Yongeza umthamo othile womoya kwikhonkrithi, kwaye ukuba umxholo womoya ukhula nge-1%, amandla aya kuncipha malunga ne-5%. Ngoko ke, xa ulungiselela ikhonkrithi yomgangatho ophezulu, umxholo womoya kufuneka ube malunga ne-3%, kwaye i-air-entraining agents kufuneka isetyenziswe ngokuqaphela. Nangona kunjalo, ukusetyenziswa kwe-air-entraining agents kunenzuzo ngaphezu kokungonakali ekusebenzeni kwekhonkrithi efana ne-anti-freeze kunye ne-anti-permeability.
3 Ngethuba lokwakhiwa, i-antifreeze edibeneyo kunye nokunciphisa amanzi, i-air-entraining, i-anti-freezing kunye ne-early-power components isetyenziswa. Umsebenzi oyintloko we-antifreeze edibeneyo yokuqala yamandla kukunciphisa ukusetyenziswa kwamanzi okuxutywa kunye nokunciphisa kakhulu ukugqithisa kwamanzi akhululekile kwi-samente hydration, ngaloo ndlela ukunciphisa inani lokukhenkceza. I-agent ye-air-entraining edibeneyo ivelisa inani elikhulu lee-bubbles ezivaliweyo ezincinci kwikhonkrithi entsha, enciphisa amandla okwandisa umthamo wokukhenkceza kwikhonkrithi, iyancipha indawo yokukhenkceza, kwaye ivumela ikhonkrithi ukuba iqhubeke i-hydrate kwiqondo lokushisa elibi. Icandelo lamandla okuqala kwi-agent-entraining agent likhawuleza ukuxutywa komxube kwaye liqinise kwangethuba, ukuhlangabezana namandla abalulekileyo ngokukhawuleza kwaye ugweme umonakalo owenziwe yiqhwa. I-Nitrates, i-nitrites kunye ne-carbonates zizinto ze-antifreeze kwaye azifanelekanga ukuxutywa kwe-galvanizing kunye nokuqiniswa kwekhonkrithi. Ikhonkrithi yamanzi okusela kunye nobunjineli bokutya ayiyi kusebenzisa izixhobo zokunqanda umkhenkce eziqulethe i-agent ye-chromium yetyuwa yokuqala, i-nitrite kunye ne-nitrate. I-Antifreeze equkethe amacandelo e-urea akufanele isetyenziswe kwizakhiwo zokuhlala kunye nezakhiwo zorhwebo.
