Anionic surfactant yomwe ili mkatikumangazowonjezera zimatha kupanga tinthu tating'ono ta simenti kumwazikana kuti madzi aulere atakulungidwa ndi kaphatikizidwe ka simenti amamasulidwa, ndipo agglomerated simenti agglomerated imafalikira bwino komanso imathiridwa bwino kuti ikwaniritse mawonekedwe wandiweyani ndikuwonjezera mphamvu yamatope, kuwongolera kusakhazikika, kukana ming'alu ndi kukhazikika.
Mtondo wosakanizidwa ndi zowonjezera umatha kugwira ntchito bwino, kuchuluka kwa madzi osungira, kumamatira mwamphamvu, kosakhala ndi poizoni, kosavulaza, kotetezeka komanso kosamalira chilengedwe.Ndioyenera kupanga zomangira wamba, pulasitala, nthaka ndi matope osalowa madzi m'mafakitale osakanizidwa okonzeka, ndipo amagwiritsidwa ntchito pomanga njerwa zadongo, njerwa za ceramsite, njerwa zopanda pake, midadada ya konkriti, ndi njerwa zosawotcha zosiyanasiyana. nyumba zamakampani ndi zachitukuko.Kupanga pulasitala wamkati ndi kunja, pulasitala yosavuta ya konkriti, pansi, kuyika padenga, matope osalowa madzi, etc.
1. Ma cellulose ether
Mumatope osakaniza okonzeka,cellulose etherndi chowonjezera chachikulu chomwe chimawonjezeredwa pamlingo wochepa kwambiri, koma chikhoza kusintha kwambiri katundu wa matope onyowa ndikukhudza zomangamanga zamatope.Kusankhidwa koyenera kwa ma cellulose ethers amitundu yosiyanasiyana, ma viscosity osiyanasiyana, kukula kwa tinthu tating'ono, ma discosity osiyanasiyana ndi kuchuluka kowonjezera kudzakhala ndi zotsatira zabwino pakuwongolera magwiridwe antchito.dothi louma.
Popanga zida zomangira, makamaka matope owuma, ether ya cellulose imagwira ntchito yosasinthika, makamaka popanga matope apadera (matope osinthidwa), ndi gawo lofunikira komanso lofunikira.Cellulose ether imagwira ntchito yosunga madzi, kukhuthala, kuchedwetsa mphamvu ya simenti ya hydration, ndikuwongolera ntchito yomanga.Kusungirako madzi kwabwino kumapangitsa kuti simenti ikhale yokwanira, yomwe imatha kupititsa patsogolo kukhuthala kwamatope amatope, kupititsa patsogolo mphamvu ya matope, komanso kusintha nthawi yogwira ntchito.Kuwonjezera pa cellulose ethers kuti makina kutsitsi matope akhoza kusintha kupopera mbewu mankhwalawa kapena kupopera katundu wa matope, komanso structural mphamvu.Chifukwa chake, ether ya cellulose ikugwiritsidwa ntchito kwambiri ngati chowonjezera chofunikira mumatope osakaniza okonzeka.
2. Redispersible polima ufa
Redispersible latex ufandi powdery thermoplastic utomoni wopezedwa mwa kutsitsi kuyanika ndi kukonzedwa wotsatira waemulsion ya polima.Amagwiritsidwa ntchito pomanga, makamaka matope owuma a ufa kuti awonjezeremgwirizano, mgwirizano ndi kusinthasintha.
Udindo wa ufa wa latex wopangidwanso mumatope: pambuyo kubalalitsidwa kwaredispersible polima ufa, imapanga filimu ndikuchita ngati chomatira chachiwiri kuti chiwonjezere kumamatira;colloid yoteteza imatengedwa ndi matope ndipo sichidzawonongedwa ndi madzi pambuyo pa kupanga filimu kapena kubalalitsidwa kwachiwiri;utomoni wa polima wopangidwa ndi filimu umagawidwa mu matope onse monga kulimbikitsa, motero kumawonjezera mgwirizano wa matope.
Mumatope onyowa, ufa wosungunuka wa polima ukhoza kupititsa patsogolo ntchito yomanga, kupititsa patsogolo kayendetsedwe ka kayendetsedwe kake, kuonjezera thixotropy ndi kukana kwa sag, kupititsa patsogolo mgwirizano, kutalikitsa nthawi yotsegula, komanso kusunga madzi.Mtondo ukachiritsidwa, ukhoza kupititsa patsogolo mphamvu.Kulimba kwamphamvu, kuwonjezereka kwamphamvu kwamphamvu, kuchepa kwa zotanuka modulus, kufooka kwachulukidwe, kuchulukirachulukira kwazinthu, kuchulukitsidwa kwamphamvu, kulimba kwamphamvu kolumikizana, kuchepa kwa kuya kwa carbonization, kuchepa kwa kuyamwa kwamadzi, ndikupanga zinthuzo kukhala katundu wa hydrophobic ndi zina zotero.
3.Mpweya kuphunzitsa wothandizira
Air-entraining wothandizila, wotchedwanso aerating wothandizila, amatanthauza kuyambitsidwa kwa tinthu tating'onoting'ono ta mpweya tomwe timagawirana molingana ndi kusanganikirana kwa matope, komwe kumatha kuchepetsa kugwedezeka kwamadzi mumtondo, zomwe zimapangitsa kuti pakhale dispersibility komanso kuchepetsa kusakaniza kwamatope.Zowonjezera za magazi ndi kulekanitsa.Komanso, kumayambiriro zabwino ndi khola mpweya thovu komanso bwino workability.Kuchuluka kwa mpweya woyambitsidwa kumadalira mtundu wa matope ndi zida zosakaniza zomwe zimagwiritsidwa ntchito.
Ngakhale kuchuluka kwa mpweya-entraining wothandizila ndi kochepa kwambiri, mpweya-entraining wothandizila ali ndi chikoka chachikulu pa ntchito okonzeka osakaniza matope.Ikhoza kusintha bwino ntchito ya matope osakaniza okonzeka bwino, kumapangitsa kuti matope asawonongeke komanso kuti asawonongeke ndi chisanu, komanso kuchepetsa kachulukidwe kamatope., sungani zipangizo ndi kuonjezera malo omanga, koma kuwonjezereka kwa mpweya wopangira mpweya kudzachepetsa mphamvu ya matope, makamaka matope osagwira ntchito.Choncho, kuchuluka kwa mpweya-entraining wothandizira ayenera mosamalitsa ankalamulira, ndi mpweya zili matope, ntchito yomanga ndi The mphamvu wachibale kudziwa mulingo woyenera kwambiri kuchuluka kwa Kuwonjezera.
4. Wothandizira mphamvu zoyambirira
Wothandizira mphamvu woyambirira ndi chowonjezera chomwe chingathe kufulumizitsa kukula kwa mphamvu yoyambirira ya matope.Ambiri aiwo ndi ma electrolyte osakhazikika, ndipo ena ndi ma organic compounds.
Wothandizira mphamvu woyambirira wa matope osakaniza okonzeka amafunika kukhala ufa ndi wouma.Calcium formate ndi yomwe imagwiritsidwa ntchito kwambiri mumatope osakaniza okonzeka.Kashiamu formate akhoza kusintha oyambirira mphamvu ya matope ndi imathandizira hydration wa tricalcium silicate, amene ali ndi ena kuchepetsa madzi kwenikweni, ndi thupi katundu wa kashiamu formate ndi khola firiji.Sizosavuta kuphatikizira, ndipo ndizoyenera kugwiritsa ntchito mumatope owuma a ufa.
5. Madzi ochepetsera
Madzi ochepetseraamatanthauza chowonjezera chomwe chingachepetse kuchuluka kwa kusakaniza madzi pansi pa chikhalidwe chakuti kusasinthasintha kwa matope kumakhala kofanana.SuperplasticizersNthawi zambiri zimakhala zopangira zinthu, zomwe zitha kugawidwa m'magulu awiri: ma superplasticizer wamba, superplasticizers, superplasticizers oyambirira-mphamvu, retang superplasticizers, retang superplasticizers, and superplasticizers malinga ndi ntchito zawo.
Chotsitsa madzi chomwe chimagwiritsidwa ntchito popanga matope okonzeka osakanizidwa chimafunika kukhala chaufa komanso chowuma.Mankhwala ochepetsera madzi oterewa amatha kumwazikana mofanana mumatope a ufa wouma popanda kuchepetsa moyo wa alumali wa matope okonzeka osakaniza.Pakali pano, kugwiritsa ntchito madzi kuchepetsa wothandizila mu matope okonzeka wothira zambiri simenti kudziletsa leveling, gypsum kudziletsa leveling, mtanda kukankha matope, madzi matope putty, putty, etc. Kusankhidwa kwa madzi kuchepetsa wothandizila zimadalira zosiyanasiyana zopangira ndi katundu wamatope osiyanasiyana.kusankha.
Zowonjezera matope okonzeka zimaphatikizanso ma retarders, ma accelerator,ulusi, mafuta odzola a thixotropic, defoaming agents, etc., omwe amawonjezeredwa malinga ndi mitundu yosiyanasiyana ya matope.Zowonjezera izi zimagwiritsidwa ntchito mumatope osakaniza kuti abweretse kuwongolera kwa ntchito zomwe zili ngati zokometsera za kuphika chakudya.Zimawonjezedwa ku mbale kuti ziwalitse mtundu wa mbale, kuonjezera kukoma, ndi kutseka zakudya, kuti mitundu yosiyanasiyana ya zakudya.matope okonzeka osakanizaakhoza kuchita bwino.Chida chamatsenga chogwiritsidwa ntchito bwino pama projekiti amatope owuma.
