Ukuhambelana kwepolycarboxylate superplasticizerkunye neminye imixube

polycarboxylate superplasticizerkwaye ezininzi ii-superplasticizers azikwazi ukuxutywa kwaye zihlanganiswe nakweyiphi na imilinganiselo efana ne-naphthalene kunye ne-aliphatic superplasticizers.Umzekelo, isiphumo esibi ekugcinweni kwe-plastic slump yeyona nto inkulu xa i-polycarboxylic acid kunye ne-naphthalene water reducer idityanisiwe, kwaye ingqalelo ekhethekileyo kufuneka ihlawulwe.Oku kuye kwabangela ukuba abaninzi abavelisi bokunciphisa amanzi e-polycarboxylate badibanise utywala oomama kunye nemisebenzi eyahlukeneyo ekhethekileyo efana nokugcinwa kwe-slump kunye nokomelela kwangaphambili ukuziqhelanisa neemfuno zokwakhiwa kwekhonkrithi ngamaxesha ahlukeneyo onyaka, izixhobo kunye nemilinganiselo yokuxuba, kwaye ekugqibeleni bazuze iziphumo ezanelisayo.Nangona kunjalo, ukuhlanganiswa kunye nokusetyenziswa okusebenzayo kotywala bukamama kufuna ixesha elithile, kwaye olunye uhlobo lotywala lukamama alukwazi ukusombulula iingxaki ezininzi kubunjineli bokusetyenziswa kwee-superplasticizers.Sisongezo esiyimfuneko ekusetyenzisweni kwepolycarboxylate superplasticizer, kwaye kubaluleke kakhulu ukusombulula iingxaki zobuchwepheshe ezijongene nesayithi lobunjineli ngokusebenzisa iimpawu zotywala omama kunye neskimu sokudibanisa ngokomzimba sezinto ezincinci.Kucetyiswa ukuba usebenzise ipolycarboxylate superplasticizerngokudibanisa namanye amacandelo.Qinisekisa ukuba uqinisekise isiphumo kodibaniso kunye nempembelelo yokwenene kwikhonkrithi ngokusebenzisa iimvavanyo, kwaye ke ugwebe ukubapolycarboxylate superplasticizerinokudityaniswa namanye amacandelo.

Ingxaki yokungunda yokugcina yepolycarboxylate superplasticizer

Xa ipolycarboxylate superplasticizerigcinwa kwiqondo lobushushu eliphezulu ehlotyeni, izinto zokungunda ezifana nokuphuma kwevumba elibi, ukugqabhuka kwemiphanda yokupakisha etywiniweyo, iindawo ezidadayo kumphezulu wolwelo kwitanki yokugcina evulekileyo, kunye nezinto ezidadayo ezimile okwemilo zihlala zisenzeka.Esona sizathu kukuba yonke inkqubo yepolycarboxylate superplasticizerukusuka kwimveliso ukuya ekusetyenzisweni nasekusetyenzisweni kugcinwa kwimeko yebhaktiriya yendalo, ngelixa amacandelo aqhelekileyo asetyenziswa njengeswekile kunye ne-hydroxycarboxylates zibonelela ngokungunda.Izondlo ezigqwesileyo, kwindawo yokushisa okufanelekileyo kunye nomswakama kunye ne-pH engathathi hlangothi, inani le-fungi landa ngokukhawuleza.Emva kokufa kwefungus, kushiyeka inani elikhulu lezidumbu, nto leyo engunobangela wesifo sokungunda.polycarboxylate superplasticizer.Ngoko ke, izithako ezisebenzayo kwi-mildewedpolycarboxylate superplasticizerazichaphazeleki kakhulu, kwaye ukusebenza kwesicelo kuzinzile.

Ukungundapolycarboxylate superplasticizerinephunga elinamandla kunye ne-foam eninzi phezu komhlaba, engabambisani kwimpilo yabasebenzi kunye nomlinganiselo ochanekileyo we-superplasticizer.Kuyimfuneko ukuthatha amanyathelo okuyicinezela.Phakathi kwabo, eyona ndlela isebenzayo kukuxuba i-bactericides ukufezekisa umphumo we-bacteriostasis kunye nokuvala inzala.Ngexesha elifanayo, iindlela ezifana nokulungelelanisa i-pH ye-agent yokunciphisa amanzi ukuba ingathathi hlangothi (pH≤3. okanye i-pH> 9.0) kunye nokutshintsha uhlobo lwe-retarder lunokusetyenziswa kwakhona.
