Kusiyana Pakati pa Zowonjezera ndi Zowonjezera

Kusiyana Kwakukulu - Zowonjezera vs Zowonjezera

Zowonjezera ndi zophatikizira ndi zinthu zomwe zimawonjezeredwa kuzinthu zina kuti zithandizire kukonza kwawo kwamankhwala ndi thupi.Ngakhale kuti zonsezi ndi zigawo zomwe zimawonjezeredwa kuzinthu zina, pali kusiyana pakati pa zowonjezera ndi zosakaniza pankhani ya simenti ndi zosakaniza za konkire.Zowonjezera zitha kukhala zowonjezera chakudya kapena china chilichonse chowonjezeredwa ku chinthu china pang'ono kuti chiwongolere kapena kuchisunga.Admixtures, kumbali ina, ndi zigawo zomwe zimawonjezeredwa kusakaniza konkire pamene mukusakaniza.Kusiyanitsa kwakukulu pakati pa zowonjezera ndi zowonjezera ndikuti zowonjezera zimawonjezeredwa ku simenti panthawi yopanga kuti zipeze zatsopano za simenti pamene zosakaniza zimawonjezeredwa ku zosakaniza za konkire pamene mukusakaniza kuti mupeze zatsopano.

Kodi Zowonjezera ndi chiyani

Zowonjezera ndi zinthu zomwe zimawonjezeredwa ku simenti panthawi yopanga kuti zipeze zatsopano za simenti.Zopangira zomwe zimagwiritsidwa ntchito popanga simenti ndi laimu, silika, alumina ndi iron oxide.Zinthu zimenezi amazipera kukhala ufa wosalala ndipo amazisakaniza kenako n’kuzikazinga.Kutentha kwa kusakaniza kumeneku kufika pafupifupi 1500oC kudzayambitsa machitidwe angapo a mankhwala omwe amapereka mankhwala omaliza a simenti.

Kuti mupeze zinthu zomwe mukufuna, zowonjezera zosiyanasiyana zimawonjezeredwa ku simenti popanga.

Ma Accelerator
Ma Accelerator amawonjezeredwa kuti achepetse nthawi yokhazikika ya simenti ndikufulumizitsa kukula kwa mphamvu zopondereza.

Obwezera
Ma retarders amawonjezera nthawi yokhazikika ya simenti.Izi zimathandiza simenti kukhala ndi nthawi yokwanira yoyika matope m'zitsime zakuya.

Obalalitsa
Ma dispersants amawonjezedwa kuti achepetse kukhuthala kwa simenti slurry ndikuwonetsetsa kuti matope amachotsa bwino pakuyika.

Fluid Loss Control Agents
Mankhwala oletsa kutaya madzi amadzimadzi amawongolera kutaya kwa madzi kuchokera ku simenti kupita ku mapangidwe.

Ma accelerators ena owonjezeredwa ku simenti ndi calcium chloride (CaCl2), sodium chloride (NaCl), madzi a m’nyanja ndi potassium chloride (KCl).

Kodi Admixtures ndi chiyani
Admixtures ndi zigawo za mankhwala zomwe zimawonjezeredwa ku zosakaniza za konkire pamene zikusakanikirana kuti zipeze zatsopano.Zosakaniza ndizo zigawo za konkire kupatula simenti, madzi ndi aggregates.Zosakaniza zimawonjezeredwa ku simenti nthawi yomweyo isanayambe kapena panthawi yosakaniza konkire.

Zosakaniza zimawonjezeredwa ku:

-Mwadala amalowetsa mpweya
-Kuchepetsa kufunikira kwa madzi
-Kuwonjezera kugwira ntchito
-Sintha nthawi yokhazikika
-Sintha mphamvu

Pali mitundu yosiyanasiyana ya zosakaniza zomwe zili pansipa ndi zitsanzo zina.

Zosakaniza zolowetsa mpweya - mchere wa matabwa, zotsukira, mchere wa mafuta acids.
Plasticizers
Zosakaniza zochepetsera madzi - lignosulfonates, hydroxylated carboxylic acid, etc.
Zowonjezera zowonjezera - calcium chloride, sodium thiocyanate, etc.
Kuchepetsa zosakaniza - lignin, borax, shuga, etc.
Corrosion inhibitors, etc.

Kusiyana Pakati pa Zowonjezera ndi Zowonjezera

Tanthauzo
Zowonjezera: Zowonjezera ndi zigawo za mankhwala zomwe zimawonjezeredwa ku simenti popanga kuti apeze zinthu zatsopano za simenti.

Zosakaniza: Zosakaniza ndi zigawo za mankhwala zomwe zimawonjezeredwa ku zosakaniza za konkire pamene zikusakaniza kuti zipeze zatsopano.

Zopangira
Zowonjezera: Zowonjezera zimawonjezeredwa ku simenti.

Zosakaniza: Zosakaniza zimawonjezeredwa ku konkire.

Kuwonjezera
Zowonjezera: Zowonjezera zimawonjezeredwa ku simenti popanga.

Zosakaniza: Zosakaniza zimawonjezeredwa ku konkire isanayambe kapena panthawi yosakaniza.

Mitundu Yosiyana
Zowonjezera: Zowonjezera zosiyanasiyana zimayikidwa ngati ma accelerators, retarders, dispersants, controls control agents, etc.

Zosakaniza: Zosakaniza zosiyanasiyana zimayikidwa ngati zowonjezera mpweya, mapulasitiki, zosakaniza zochepetsera madzi, ndi zina zotero.

Mapeto
Zowonjezera zimawonjezeredwa ku simenti popanga.Zosakaniza zimawonjezeredwa kusakaniza konkire isanayambe kapena panthawi yosakaniza.Kusiyanitsa kwakukulu pakati pa zowonjezera ndi zowonjezera ndikuti zowonjezera zimawonjezeredwa ku simenti panthawi yopanga kuti zipeze zatsopano za simenti pamene zosakaniza zimawonjezeredwa ku zosakaniza za konkire pamene mukusakaniza kuti mupeze zatsopano.
