1.Intshayelelo yemveliso

Uhlobo lwamandla aphezulu kwangethuba iPolycarboxylate superplasticizer yikama-eyakhiwe ngepolycarboxylate superplasticizer ehlanganiswe ne-carboxylic acid kunye ne-ester macromonomers.Amandla okuqala ekhonkrithi exutywe nale mveliso anokuphuculwa kakhulu, kwaye amandla kamva awanciphisi.Ifanelekile kwikhonkrithi ye-precast kunye neentlobo ezahlukeneyo zamandla aphezulu kunye ne-high-performance concrete, enokunciphisa ixesha lokuchithwa kunye nokuphucula ukusebenza kakuhle kwe-mold.Le mveliso inezi mpawu zilandelayo:

(1) Izinga eliphezulu lokucuthwa kwamanzi, ukusasazwa kakuhle kunye nefuthe logcino lokusasazwa kwisamente;
(2) Isiphumo sokuqala sokuphucula amandla ekhonkrithi sicacile, kwaye amandla amva awanakucutheka;
(3) Isiqulatho somoya siphantsi, esinciphisa umphumo ombi we-bubbles emoyeni kwikhonkrithi kwisakhiwo sangaphakathi, kwaye unokuphucula ukubonakala kwekhonkrithi ngexesha elifanayo;
(4) Ukulungelelaniswa okufanelekileyo kumabakala ahlukeneyo kunye nabavelisi abahlukeneyo besamente, kunye nokuhambelana kakuhle nemixube.

2. Iimpawu zeMveliso

(1) Izinga eliphezulu lokunciphisa amanzi: Le mveliso inomlinganiselo we-0.15-0.3% (ngokwemiqathango yomxholo oqinileyo) kunye nomlinganiselo wokunciphisa amanzi we-18-40%, onokuhlangabezana neemfuno ze-ultra-low water-cement. umlinganiselo kunye nekhonkrithi ephezulu yamanzi.Yonga i-10 ukuya kwi-20% yesamente.
(2) Ilahleko ephantsi ye-slump: Le mveliso yazisa amatyathanga amade ecala le-macromolecules kwinkqubo yokudibanisa, kwelinye icala, inqanda ukugcwala kwamanzi, kwaye kwelinye icala ibonelela ngesithintelo esiqinileyo, esinokugcina iplastiki eludaka ixesha elide, kwaye inokusebenza kakuhle.ukugcinwa kokudodobala.
(3) Ukusebenza okugqwesileyo: Ikhonkrithi elungiselelwe kunye nale mveliso inokusebenza kakuhle, akukho ulwahlulo, akukho delamination, ukudibanisa okulungileyo, kwaye ifanelekile ukuthutha umgama omde kunye nokupompa.
(4) Ukuqina okuphezulu: Le mveliso i-polymerized ngesisombululo samanzi se-radical samahhala, esinomxholo omncinci we-chloride ion, kuphela isixa esincinci se-alkali esisetyenziselwa ukungathathi hlangothi, umxholo we-alkali uphantsi kakhulu, umxholo we-alkali kunye nomxholo we-ion we-chloride ulinganiselwe. izinzile, kunye neklorini ephantsi kunye ne-alkali ephantsi ingaba nkulu.Ukuphucula ngokuphawulekayo ukuqina kwekhonkrithi.
(5) I-shrinkage ephantsi kunye ne-anti-cracking: Le mveliso inokunciphisa ukushisa kwe-hydration, ukulibazisa i-peak exothermic, kwaye ifanelekile kwikhonkrithi enkulu, enokunciphisa ngokufanelekileyo ukuchithwa kwekhonkrithi okubangelwa ukuhluka kobushushu be-hydration.
(6) Ukukhuselwa kokusingqongileyo okuluhlaza: Le mveliso ifakwe i-polymerized kunye nesisombululo se-aqueous samahhala.Iimathiriyeli ekrwada aziqulathanga i-formaldehyde kunye nezinye izinto ezingcolisayo.Akukho manzi amdaka kunye nokukhutshwa kwamanzi amdaka ngexesha lenkqubo yokudibanisa, kwaye umthwalo wokusingqongileyo uphantsi kakhulu.Luhlobo olutsha lwezinto zokwakha eziluhlaza kunye nokusingqongileyo.
njengolunye uhlobo lokunciphisa amanzi asebenza ngokufanelekileyo imixube,
