Indlela Izongezo zodaka eziLungileyo eziDibeneyo ziPhucula uHlahlelo lweNtsebenzo yodaka

01. Idibansi yodaka esele ilungile

I-anionic surfactant equlethwe kwi-additive-mixed mortar additive kwiprojekthi inokwenza ukuba iinqununu ze-samente zihlakazeke, zikhulule amanzi akhululekile afakwe kwi-cement aggregate, asasaze ngokupheleleyo ubunzima be-cement edibeneyo, kwaye i-hydrate ngokupheleleyo ukufezekisa isakhiwo esincinci kwaye ukwandisa ukuxinana kodaka. Amandla, ukuphucula ukunganyangeki, ukuchasana nokuqhekeka kunye nokuqina. Udaka oluxutywe kunye nezongezo zodaka ezisele zixutywe zinokusebenza kakuhle, izinga eliphezulu lokugcinwa kwamanzi, amandla okubambisana anamandla, angenabutyhefu, angenabungozi, akhuselekile kwaye anobuhlobo bendalo ngexesha lokusebenza. Ilungele ukuveliswa kweemasonry eziqhelekileyo, ukutyabeka, umhlaba, kunye nodaka olungenamanzi kwiifektri zodaka ezisele zixutywe. Isetyenziselwa ukwakha kunye nokwakhiwa kwezitena zodongwe zekhonkrithi, izitena ze-ceramsite, izitena ezingenanto, iibhloko zekhonkrithi, izitena ezingatshiyo kwizakhiwo ezahlukeneyo zemizi-mveliso kunye nezoluntu. Ukwakhiwa kweendonga zangaphakathi nangaphandle, ukubethelwa kodonga lwekhonkrithi, umgangatho kunye nomgangatho wophahla, udaka olungenamanzi, njl.

02. Iselulosi ether

Kwi-mortar edibeneyo edibeneyo, i-cellulose ether iyona nto yokongeza enokuphucula kakhulu ukusebenza kodaka olumanzi kwaye ichaphazele ukwakhiwa kodaka. Ukukhethwa okufanelekileyo kwee-cellulose ethers zeentlobo ezahlukeneyo, i-viscosities eyahlukeneyo, ubukhulu beentlobo ezahlukeneyo, iidigri ezihlukeneyo ze-viscosity kunye neemali ezongezelelweyo ziya kuba nefuthe elihle ekuphuculeni ukusebenza kwe-powder mortar.

Ukuveliswa kwe-ether ye-cellulose yenziwe ngokukodwa kwimicu yendalo ngokuchithwa kwe-alkali, ukuxutywa kwe-grafting (etherification), ukuhlamba, ukomisa, ukuntywila kunye nezinye iinkqubo. Kwimveliso yezinto zokwakha, ngakumbi udaka oluyimpuphu eyomileyo, i-cellulose ether idlala indima engenakulinganiswa, ngakumbi ekuveliseni udaka olukhethekileyo (udaka olulungisiweyo), luyinto eyimfuneko kwaye ibalulekileyo. I-Cellulose ether idlala indima yokugcina amanzi, ukuqina, ukulibazisa amandla okuhambisa i-samente, kunye nokuphucula ukusebenza kokwakhiwa. Umthamo olungileyo wokugcinwa kwamanzi wenza i-samente i-hydration igqibeke ngakumbi, inokuphucula i-viscosity emanzi yodaka olumanzi, ukwandisa amandla okubopha udaka, kunye nokulungelelanisa ixesha. Ukongeza i-cellulose ether kumatshini wokutshiza udaka kunokuphucula ukutshiza okanye ukumpompa ukusebenza kunye namandla okwakhiwa kodaka. Ngoko ke, i-cellulose ether isetyenziswa ngokubanzi njengesongezo esibalulekileyo kwi-mortar esele ixutywe. I-cellulose ethers esetyenziswa kudaka olusele luxutywe ikakhulu yi-methyl hydroxyethyl cellulose ether kunye ne-methyl hydroxypropyl cellulose ether. , bathatha ngaphezu kwe-90% yesabelo semarike.

03. Umgubo welatex ophinda uhlakazwe

Redispersible latex powder yi-powdery thermoplastic resin efunyenwe ngokumisa isitshizi kunye nokucutshungulwa okulandelayo kwe-polymer emulsion. Isetyenziswa ikakhulu kulwakhiwo, ingakumbi udaka lomgubo owomileyo ukunyusa ubumbano, ubumbano kunye nokuguquguquka.

Indima ye-latex powder ehlaziywayo kwi-mortar: i-latex powder edibeneyo yenza ifilimu emva kokusabalalisa kwaye isebenze njenge-adhesive yesibini yokuphucula ukubambelela; i-colloid ekhuselayo ixutywa yinkqubo yodaka kwaye ayiyi kutshatyalaliswa ngamanzi emva kokubunjwa kwefilimu Okanye i-dispersions ezimbini; i-resin ye-polymer eyenza ifilimu isasazwa kulo lonke inkqubo yodaka njengento yokuqinisa, ngaloo ndlela ikwandisa ukudibanisa komdaka.

I-latex powder edityanisiweyo kumdaka omanzi inokuphucula ukusebenza kokwakhiwa, ukuphucula ukusebenza kokuhamba, ukwandisa i-thixotropy kunye nokuxhatshazwa kwe-sag, ukuphucula ukubambisana, ukwandisa ixesha elivulekileyo, ukwandisa ukugcinwa kwamanzi, njl njl. Emva kokuba udaka lunyangekile, lunokuphucula amandla okuqina. Amandla okugoba, ukomeleza amandla okugoba, ukuncipha kwemodyuli yeelastiki, ukonakala okuphuculweyo, ukonyuka kokuhlangana kwezinto, ukuphuculwa kokunganyangeki, ukomelela okuqinileyo, ukucutha ubunzulu bekhabhoni, ukunciphisa ukufunxwa kwamanzi kwemathiriyeli, kwaye yenze ukuba imathiriyeli ibenesixhobo sokugxotha amanzi. iziphumo.

04. I-arhente yokungenisa umoya

I-arhente yokungenisa umoya, eyaziwa ngokuba yi-air-entraining agent, ibhekiselele ekuqalisweni kwenani elikhulu lamaqamza amancinci asasazwe ngokufanayo ngexesha lenkqubo yokuxuba udaka, enokunciphisa ukuxinana komphezulu wamanzi kudaka, okukhokelela ekusasazekeni okungcono. kunye nomxube oncitshisiweyo wodaka. Ukopha, ukwahlula izongezo. Ukongeza, ukungeniswa kwamaqamza omoya acolekileyo kwaye azinzileyo nawo aphucula umsebenzi wokwakha. Ubungakanani bomoya obungeniswayo buxhomekeke kuhlobo lodaka kunye nezixhobo zokuxuba ezisetyenzisiweyo.

Nangona inani le-arhente yokungenisa umoya lincinci kakhulu, i-agent-entraining agent inempembelelo enkulu ekusebenzeni kodaka oluxutywe, olunokuphucula ngokufanelekileyo ukusebenza kodaka oluxutywe kakuhle, ukuphucula ukunganyanzeki kunye nokumelana neqabaka yodaka. , kwaye unciphise ubuninzi bomdaka , gcina izinto eziphathekayo kunye nokwandisa indawo yokwakha, kodwa ukongezwa kwe-agent yokungenisa umoya kuya kunciphisa amandla omdaka, ngakumbi udaka oluxinzelelekileyo. Ukuqina konxulumano ukumisela idosi efanelekileyo.

05. I-arhente yamandla yangaphambili

I-ejenti yamandla yangaphambili yisongezo esinokukhawulezisa ukuphuhliswa kwamandla okuqala odaka, uninzi lwawo luyi-electrolyte ye-inorganic, kwaye ezimbalwa ziyi-organic compounds.

I-accelerator yodaka oluxutyiweyo olulungeleyo luyafuneka ukuba lube ngumgubo kwaye lome. I-calcium formate yeyona isetyenziswa kakhulu kudaka olusele luxutywe. Ifomati yeCalcium inokuphucula amandla okuqala odaka, kwaye ikhawulezise i-hydration ye-tricalcium silicate, enokunciphisa amanzi kwinqanaba elithile. Ngaphezu koko, iipropathi ezibonakalayo ze-calcium formate zizinzile kwiqondo lokushisa. Akulula ukuba i-agglomerate kwaye ifaneleke ngakumbi ukufakwa kwi-powder mortar eyomileyo.

06. Isinciphisi samanzi

I-agent yokunciphisa amanzi ibhekisela kwisongezo esinokunciphisa inani lokuxuba amanzi phantsi kweemeko zokugcina ukuhambelana kodaka ngokusisiseko. Isinciphisi samanzi ngokuqhelekileyo sisixhobo sokusebenza emanzini, esinokwahlulwa sibe sinciphisi samanzi esiqhelekileyo, izinciphisi zamanzi ezisebenza kakuhle, izinciphisi zamanzi kwangethuba, izinciphisi zamanzi ezibaxekileyo, izinciphisi zamanzi ezingasebenzi kakuhle kunye nezinciphisi zamanzi ezingenisa umoya ngokwemisebenzi yazo. Iintlobo ngeentlobo.

Isinciphisi samanzi esisetyenziselwa udaka olusele luxutywe lufuneka lube ngumgubo kwaye some. Umnciphisi wamanzi onjalo unokusasazwa ngokulinganayo kwi-powder mortar eyomileyo ngaphandle kokunciphisa ubomi beshelufu yodaka olulungeleyo. Okwangoku, ukusetyenziswa kwe-arhente yokunciphisa amanzi kumdaka olungelelanisiweyo ngokuqhelekileyo kwi-sement self-leveling, i-gypsum self-leveling, udaka lokutyabeka, udaka olungenamanzi, i-putty, njl njl. iipropati zodaka. Khetha.
