Polycarboxylate Superplasticizerithathwa njengomxube osebenza kakhulu. Abantu bahlala belindele ukuba bakhuseleke, basebenziseke ngakumbi, basebenze ngakumbi, kwaye baziqhelanise ngakumbi kune-admixtures ye-naphthalene yendabuko kwizicelo, kodwa eyona meko ayiyonyani. Uhlangabezana neengxaki ezahlukeneyo. Ke, yeyiphi imiqathango yokusetyenziswapolycarboxylic acidimixube?
1. Polycarboxylate Superplasticizeridinga ukulawula ubungakanani bamanzi ngokufanelekileyo. Ngakolunye uhlangothi, ukuze kuqinisekiswe umlinganiselo wokubopha amanzi, kwelinye icala, ngenxa yokubapolycarboxylate superplasticizerinochuku kakhulu ekusetyenzisweni kwamanzi. Iimpawu eziqhelekileyo ezibonisa ukusebenza kwemixube ekhonkrithi ziquka umbane, ukudibanisa kunye nokugcinwa kwamanzi. Ngokubapolycarboxylate superplasticizerinomdla kakhulu ekusebenziseni amanzi, ngamanye amaxesha ukusetyenziswa kwamanzi kwandiswa kuphela nge-1kg ~ 3kg ngexesha lovavanyo kunye nenkqubo yokuvelisa. Ukopha kakhulu, iimfumba zamatye atyhilekileyo, ukubamba umzantsi we-mat, njl., akunakuqinisekisa ukufana komxube wekhonkrithi. Ngoko ke, ukusetyenziswa kwamanzi unilateral kufuneka kulawulwe ngokungqongqo ngexesha lokuvelisa.
2. Lawula umxholo wepolycarboxylic acid. Isiqulatho esingonelanga sekhonkrithi sibonakaliswa ngokulahleka ngokukhawuleza, ilahleko enkulu, kunye nokungabi namanzi; kakhulu kuya kubangela ukopha kakhulu, ulwahlulo, kunye nokubamba emazantsi. Kuyimfuneko ukwenza iimvavanyo ezininzi ukufumanisa eyona nto ifanelekileyo phakathi kokusetyenziswa kwamanzi kunyepolycarboxylate superplasticizerumxholo. Inqaku, oko kukuthi, ukusetyenziswa kwamanzi okugqibeleleyo kunye nedosi edibeneyo.
3. Akuvunyelwe ngokungqongqo ukudibanisa i-naphthalene admixtures. Ngokweeprojekthi ezahlukeneyo, uninzi lwezityalo zokuxuba ikhonkrithi kufuneka zisebenzise i-naphthalene admixtures ngelixa usebenzisapce. Ukuba iimeko zivuma, kungcono ukusebenzisa kwizikhululo ezahlukeneyo. Ukuba iyunithi efanayo iqulethe zombinipolycarboxylate superplasticizerkunye nenaphthalene, isikhongozeli sokulinganisa ubunzima, umbhobho kunye nesixube somxube kufuneka zicocwe ngocoselelo xa zisetyenzwa ngenye indlela, kunye netanki yekonkile kufuneka nayo icocwe. Coca kwaye ulayishe kwakhona. Ukubapolycarboxylic acidkunye ne-naphthalene-based admixtures ixutywe kwaye isetyenzisiwe, i-admixtures ezimbini ziya kusabela ukwenza ikhonkrithi "ibekwe ngokukhawuleza", ebangela ukuba isithuthi sonke sikhutshwe.
4.Ukuqinisa uhlolo lwepolycarboxylate superplasticizerimixube. Ngelixa ujonga i-admixtures, thatha iisampulu kwizinto ezisetyenziswayo ezikhoyo, kwaye uvavanye ikhonkrithi ngokweemfuno zobugcisa zeprojekthi. Ukuba kukho naziphi na iingxaki ezifunyenweyo, nceda ucele ngokukhawuleza abasebenzi bezobugcisa bomenzi we-admixture ukuba benze uhlengahlengiso.
Ngamafutshane, ikhonkrithiumxube we-polycarboxylic acidluhlobo olutsha lwemathiriyeli. Xa kuthelekiswa nezinciphisi zamanzi zemveli, ayinayo kuphela idosi encinci, inqanaba lokwehliswa kwamanzi aphezulu, iklorini ephantsi kunye nealkalinity ephantsi, kunye nesiphumo esicacileyo sokugcinwa kwe-slump. Ukuphucula ukuqina kwesakhiwo sekhonkrithi, kunye nenkqubo yokuvelisapolycarboxylate superplasticizerisinciphisi samanzi sicocekile kwaye asingcoliseki. Luhlobo olutsha lokuncitshiswa kwamanzi okuluhlaza kunye nokusingqongileyo okusebenzayo okuphezulu.
