I-BT-303 Ukukhutshwa okucothayo okucothayo okuphezulu kokugcina uhlobo lwePolycarboxylate Superplasticizer
Umgaqo wobugcisa
Isakhiwo semolekyuli sale mveliso sazisa amaqela asebenzayo njengamaqela e-ester kunye namaqela e-amide ukufumana i-polycarboxylic acid superplasticizer eneempawu zokugcinwa kwe-slump.Ngaphantsi kweemeko ze-alkaline zekhonkrithi, amaqela e-ester ngokuthe ngcembe ahlanjululwa nge-hydrolyzed kumaqela e-carboxylic acid kwaye adsorbed kwi-samente.Umphezulu wamasuntswana wenza isiphumo esihle sokukhusela ukuthotywa kokucotha.
Ngaphantsi kwemeko ye-alkaline yekhonkrithi, amaqela asebenzayo kwisakhiwo se-molecular yale mveliso angakwazi ukukhulula ngokukhawuleza amaqela kunye nomphumo wokusabalalisa, kwaye adlale indima yokuqhubeka nokusabalalisa i-samente, ngaloo ndlela efezekisa umphumo wokuthintela ukulahleka kwekhonkrithi kwi-slump.
Uphawu lweMveliso
(1) Ixabiso lokugcinwa kwe-slump likhulu, kwaye ukuhla kunokufikelela ngaphezu kwe-80%yokudilika kwekhonkrithi entsha emva kweyure eyi-1, enokusombulula ngempumelelo ingxaki yokulahleka kokuthotywa kwekhonkrithi ngokukhawuleza.
(2) Ukusebenza okugqwesileyo kwekhonkrithi emva kokusetyenziswa.Ikhonkrithi entsha inokusebenza kakuhle, ukuqina okugqwesileyo kunye nokuqina.
(3) Ukuguquguquka okubanzi Inokuguquguquka okubanzi kwisamente yasePortland, i-samente yasePortland eqhelekileyo, i-slag silicate, i-fly ash simenti, i-samente ye-pozzolan kunye nemixube eyahlukeneyo.
(4) Uhlaza, ulungele ukusingqongileyo, akukho mveliso yenkunkuma emithathu kwinkqubo yokuvelisa.

Isicelo
(1) Ilungele ukulungiswa kwekhonkrithi eyomelela kwangethuba, ikhonkrithi esemva, ikhonkrithi yangaphambili, ikhonkrithi eyakhiweyo, ikhonkrithi equkuqelayo enkulu, ikhonkrithi ezenzelayo, ikhonkrithi enkulu, ukusebenza okuphezulu kunye nekhonkrithi enobuso obungenamkhethe, ngokunjalo. njengezakhiwo ezahlukahlukeneyo zemizi-mveliso nezasekuhlaleni Ikhonkrithi exutyiweyo exutyiweyo kunye ne-cast-in-situ ephakathi, ilungele ngakumbi ikhonkrithi yorhwebo yomgangatho ophantsi.
(2) Inokusetyenziswa ngokubanzi kwiiprojekthi zesizwe nezingundoqo ezifana nomzila kaloliwe ohamba ngesantya esiphezulu, amandla enyukliya, ugcino lwamanzi kunye neeprojekthi zombane oveliswa ngamanzi, iindlela ezihamba phantsi komhlaba, iibhulorho ezinkulu, iindlela ezihambahambayo, amazibuko kunye namazibuko.
(3) Isebenza kwiindidi ezahlukeneyo zemizi-mveliso kunye nokwakhiwa kwezakhiwo kunye nezityalo zokuxuba ikhonkrithi yorhwebo
Kusetyenziswa kwanjani
1. Idosi eqhelekileyo yi-0.6% ~ 1.2% (ibalwa ngokususela kwisixa sisonke sezinto zesamente), kwaye eyona dosi igqwesileyo kufuneka igqitywe ngokuvavanywa ngokwemathiriyeli yobunjineli kunye neempawu.Ilungele ukudibanisa kunye namanzi aphezulu okunciphisa i-polycarboxylic acid yokunciphisa amanzi okanye ukusebenzisa yedwa.
I-2.Le mveliso ingasetyenziselwa enye (Ngokuqhelekileyo ayikwazanga ukusebenzisa enye) Inokudibaniswa kunye nokunciphisa amanzi otywala oomama kunye nokusetha utywala obunzima bomama ukunciphisa ilahleko yekhonkrithi.Okanye i-compound enezixhobo ezisebenzayo zokufumana i-admixtures kunye ne-retarder / amandla okuqala / i-antifreeze / imisebenzi yokumpompa.Indlela yesicelo kunye neemeko kufuneka zigqitywe ngokuvavanya kunye nokudibanisa iteknoloji
3.Le mveliso ingasetyenziselwa kunye nezinye iintlobo ze-admixtures ezifana ne-ejenti yamandla okuqala, i-arhente yokungenisa umoya, i-retarder, njl., kwaye kufuneka ivavanywe ngaphambi kokusetyenziswa.Musa ukudibanisa ne-naphthalene series water reducer.
4.Xa kukho i-admixtures esebenzayo efana ne-fly ash kunye ne-slag kumlinganiselo wekhonkrithi, inani le-agent yokunciphisa amanzi kufuneka libalwe njengexabiso elipheleleyo lezinto ze-cementing.
Ukupakisha kunye nokuhanjiswa
Iphakheji: 220kgs / idrum, 24.5 tons / Flexitank, 1000kg / IBC okanye xa uceliwe
