Kutheni iPolycarboxylate Superplasticizer iguqulwa?

I-arhente yokunciphisa amanzi ekhonkrithi yenye yeendlela zobugcisa zokunciphisa idosi yesamente, ukuphucula izinga lokusetyenziswa kwentsalela yenkunkuma yemizi-mveliso, kunye nokuqonda ukuqina kunye nokusebenza okuphezulu kwekhonkrithi.Kwakhona yenye yezinto eziphambili zokuphuhliswa kwekhonkrithi ukuya kwintsimi ye-high-tech.Kwaye i-ejenti yokunciphisa amanzi yohlobo lwe-polycarboxylate (i-PC) iye yaba luhlobo lwe-arhente yokunciphisa amanzi esebenzayo kunye nophuhliso olukhawulezayo kunye neyona ndawo inkulu yemarike ngenxa yetyhefu ephantsi kunye neempawu zokukhuselwa kwendalo.Xa kuthelekiswa nemixube yemveli, imixube iye yaba yeyona nto kugxilwe kuyo kuphando lwehlabathi lonke kunye nophuhliso ngenxa ye-dispersibility ebalaseleyo kunye nokukwazi ukugcina ukudodobala.

Nangona amanzi e-polycarboxylate ehlisa i-admixture egqwesileyo ukusebenza kunye nokukwazi ukugcina i-slump efanelekileyo sele yamkelwa ngokubanzi, kodwa ngenxa yobukho bokwakheka kweeminerali, ukucolwa kwesamente, ifom yesamente yesamente kunye nomxholo, umxube wokongeza umxube, kunye nenkqubo yokuxuba umlinganiselo womxube wekhonkrithi, amanzi. inovakalelo oluphezulu kakhulu, ichaphazeleke kakhulu iimveliso ezikhoyo zisetyenziswa kakhulu kubunjineli.

Yintoni i-Polycarboxylate Series ye-Agent yokunciphisa amanzi?

I-Polycarboxylate superplasticizer luhlobo lwe-surfactant ene-carboxylic graft copolymer.Iimolekyuli zayo zinemilo yekama kwaye zinempembelelo ephezulu yokuthintela.Njengesizukulwana sesithathu se-agent ephezulu yokunciphisa amanzi emva kwe-agent ye-lignosulfonate eqhelekileyo yokunciphisa amanzi, i-naphthalene series aliphatic group, i-sulfamate kunye nezinye i-agent ephezulu yokunciphisa amanzi.

Kungenxa yokuba ulwakhiwo lwemolekyuli lusebenza kakuhle, ukuncitshiswa okuphezulu kwamanzi, umxube ophantsi womxube, gcina i-slump ilungile, iphucula kakuhle, iqulethe isixa sealkali siphantsi, ukuseta impembelelo yexesha lincinci, kwaye uninzi lokuhambelana kwesamente kulungile kwaye alungcolisi kwaye ezinye iingenelo zithathwa njengezona zinamandla zophuhliso zohlobo lwearhente yokunciphisa amanzi.

I-Polycarboxylate superplasticizer sisixhobo esitsha esisebenza kakuhle kakhulu esiphuhliswe kwaye senziwa ngempumelelo emva kwe-naphthalene, i-melamine, i-aliphatic kunye ne-sulfamate superplasticizer.Kumxholo wayo uphantsi (umxholo oqinileyo 0.15% - 0.25%) unokuvelisa amanzi afanelekileyo okunciphisa kunye nomphumo ophuculweyo, impembelelo encinci kwixesha lokumisela ikhonkrithi kunye nokugcinwa kwe-slump, ukulungelelaniswa kwe-samente kunye ne-admixture ilungile, impembelelo encinci ekomisweni. i-shrinkage yekhonkrithi (ngokuqhelekileyo ayinyuki kakhulu yokunyusa ukomisa), ngaphandle kokusetyenziswa kwe-formaldehyde kwinkqubo yokuvelisa kwaye ayikhupheli utywala, SO Umxholo ophantsi we-42- kunye ne-Cl- uye wadunyiswa ngabaphandi kunye nabanye abasebenzisi ukususela ngoku. ukuqala.

Kutheni kufuneka iPolycarboxylate Superplasticizer iguqulwe?

Xa kuthelekiswa ne-naphthalene series ephezulu esebenzayo yokunciphisa amanzi, njengokuba, nangona i-poly carboxylic acid i-arhente yokunciphisa amanzi ekunciphiseni i-slump yolondolozo lwamanzi ineenzuzo ezicacileyo kwimiba yokhuseleko lokusingqongileyo, kodwa kukho iingxaki zobugcisa kwisicelo sobunjineli esisebenzayo, njenge Ukunciphisa amanzi isiphumo semathiriyeli ekrwada ekrwada, umlinganiselo wokuxuba, ukuxhomekeka kwamanzi kwidosi yokunciphisa amanzi kukhulu kakhulu, ukusebenza kwekhonkrithi okutsha kunovakalelo kusetyenziso lwamanzi, ulungiselelo olulula lomaleko omkhulu wokwahlulwa kobumanzi.Ukungahambelani kakubi kunye nezinye ii-arhente zokunciphisa amanzi kunye namacandelo alungisiweyo kunye nozinzo olubi lwemveliso luthintela kakhulu ukusetyenziswa okubanzi kunye nophuhliso lwe-polycarboxylate yokunciphisa amanzi.

Ukuze unqobe iziphene zobugcisa kwisicelo se-polycarboxylate yokunciphisa amanzi, okanye ukuphucula ezinye okanye ezinye iimpawu zekhonkrithi (ukusebenza, ukugcinwa kwe-slump, ukunciphisa ukopha, ukuphuculwa kwamandla okuqala, ukuncipha okuphantsi, njl.), kuyimfuneko ukuguqula ikhonkrithi.

Ngokwesiqhelo, iindlela zokuguqulwa ezisetyenziswa ngokuqhelekileyo ziquka iteknoloji yokwenziwa kunye neteknoloji edibeneyo.Xa kuthelekiswa nenkqubo yokwenziwa, indlela edibeneyo ineenzuzo zokusebenza okulula kunye neendleko eziphantsi, ngoko ke isetyenziswa ngokubanzi kwizicelo eziphathekayo.Itekhnoloji yePolycarboxylate yochungechunge lwekhompawundi, luluhlu lwepolycarboxylate yokunciphisa amanzi kunye nezinye izinto (ezifana nokucotha okucothayo, i-defoamy, ukungenisa umoya, amandla okuqala kunye nezinye izinto) ngokwenxalenye ethile yodibaniso lwekhompawundi, ukuze kuphunyezwe ulungelelwaniso. indawo ephezulu yecandelo ngalinye.
