Umahluko Phakathi Kwezongezo kunye neMixube

Umahluko oPhambili – Izongezo vs Imixube

Izongezo kunye ne-admixtures zizinto zekhemikhali ezongezwa kwezinye izinto ukuphucula iikhemikhali zazo kunye neempawu zomzimba. Nangona zombini zizixhobo ezongeziweyo kwezinye izinto, kukho umahluko phakathi kwezongezo kunye ne-admixtures xa kufikwa kwimixube yesamente kunye nekhonkrithi. Izongezo zinokuba zizongezo zokutya okanye nayiphi na enye into edityaniswe kwinto ngomlinganiselo omncinci ukuyiphucula okanye ukuyigcina. I-Admixtures, ngakolunye uhlangothi, zizinto ezongezwa kumxube wekhonkrithi ngelixa udibanisa. Umahluko ophambili phakathi kwezongezo kunye ne-admixtures kukuba izongezo zongezwa kwisamente ngexesha lokuvelisa ukufumana iipropathi ezintsha zesamente ngelixa i-admixtures yongezwa kwimixube yekhonkrithi ngelixa ixutywa ukufumana iipropathi ezintsha.

Yintoni ezongeziweyo

Izongezo zizinto zekhemikhali ezidityaniswe kwisamente ngexesha lokwenziwa kwemveliso ukuze kufumaneke iipropati ezintsha zesamente. Izinto ezisetyenziswayo xa kusenziwa isamente yikalika, isilica, ialumina kunye ne iron oxide. Ezi zixhobo ziyasilwa zibe ngumgubo ocolekileyo kwaye zixutywe kulandele ukuqhotswa. Ukufudumeza lo mxube ukuya malunga ne-1500oC kuya kuqalisa inani leentshukumo zemichiza ezinika ukwakheka kweekhemikhali zokugqibela zesamente.

Ukuze ufumane iipropati ezinqwenelekayo, izongezo ezahlukeneyo zongezwa kwisamente ngelixa kuveliswa.

Ii-Accelerators
Ii-accelerators zongezwa ukunciphisa ixesha lokumisa i-samente kunye nokukhawulezisa uphuhliso lwamandla oxinzelelo.

Abasemva
Abahlaziyi bandisa ixesha lokumisa isamente. Oku kunceda isamente ibe nexesha elaneleyo lokubekwa kodaka kumaqula anzulu.

Abasasaza
I-Dispersants yongezwa ukunciphisa i-viscosity ye-sement slurry kunye nokuqinisekisa ukukhutshwa kakuhle kodaka ngexesha lokubeka.

Iiarhente zokulawula ilahleko yolwelo
Ii-arhente zokulawula ilahleko yolwelo zilawula ukulahleka kwamanzi ukusuka kwisamente ukuya kulwakhiwo.

Ezinye ii-accelerators ezifakwe kwisamente yi-calcium chloride (CaCl2), i-sodium chloride (NaCl), amanzi olwandle kunye ne-potassium chloride (KCl).

Yintoni iAdmixtures
I-Admixtures zizinto zekhemikhali ezongezwa kwimixube yekhonkrithi ngelixa zixutywa ukufumana iipropati ezintsha. Imixube ngamalungu ekhonkrithi ngaphandle kwesamente, amanzi kunye neeaggregates. I-Admixtures yongezwa kwi-samente ngokukhawuleza ngaphambi okanye ngexesha lokuxuba umxube wekhonkrithi.

Imixube yongezwa kwi:

-Ngena ngabom umoya
-Ukunciphisa imfuno yamanzi
-Ukwandisa ukusebenza
-Lungisa ixesha lokumisa
-Lungisa amandla

Kukho iindidi ezahlukeneyo zemixube ehlelwe njengalapha ngezantsi ngemizekelo ethile.

Izixube zokungenisa umoya - iityuwa zeentlaka zomthi, ezinye izicoci zokwenziwa, iityuwa zepetroleum acid.
Iiplastiki zeplastiki
I-admixtures yokunciphisa amanzi - i-lignosulfonates, i-hydroxylated carboxylic acids, njl.
I-accelerating admixtures - i-calcium chloride, i-sodium thiocyanate, njl.
Ukunciphisa i-admixtures - i-lignin, i-borax, ishukela, njl.
I-Corrosion inhibitors, njl.
