A. Arhente yokunciphisa amanzi

Elinye lokusebenzisa i-arhente yokuncitshiswa kwamanzi kukunciphisa ukusetyenziswa kwamanzi kwikhonkrithi kunye nokuphucula ulwelo lwekhonkrithi phantsi kwemeko yokugcina umyinge wamanzi engaguqukiyo, ukuze kufezekiswe iimfuno zothutho nekhonkrithi. Uninzi lwamanzi enciphisa i-admings inamachaphaza agcweleyo. Ukuba i-dosage egxunyelweyo idlulile, inqanaba lokuphuhlisa amanzi aliyi kunyuka, kwaye ukopha kwaye ukwahlulahlulo kuya kwenzeka. I-dosage egcweleyo ihambelana nazo zombini izinto ezinqabileyo zekhonkrithi kunye nomxube wekhonkrithi.

 

1. I-Naphthalene Superplaistiber

I-Naphthalene SuperplaistiberUnokwahlulwa kuba yimveliso ephezulu kakhulu (i-NA2SSO4 <3%), iimveliso eziphakathi (i-NA24) 3% ~ 10%) kunye neemveliso zoxinaniso (i-NA24) kunye nomxholo we-NA24. Uluhlu lwe-dosiage ye-Naphthalene eqondakalayo: Ipowder yi-0.5 ~ 1.0% yesamente. Umxholo oqinileyo wesisombululo yi-38% ~ 40%, isixa semali yokudibanisa yi-1.5% ~ 2.5% ye-qumesment yesamente, kunye nexabiso lokunciphisa amanzi yi-18% ~ 25%. U-Naphthalene uthotho wamanzi unciphise unciphiso alusoli nomoya, kwaye alinampembelelo kangako kwixesha lokuseta. Ingadityaniswa nge-sodium gluconate, iswekile, i-hydroxycarboxycylic acid kunye ne-icic, i-cicric amergadi yomoya, kwaye ilahlekelwe ngokufanelekileyo yilahleko. Ukungancedi kakuhle kumanzi aphezulu e-Naphthalene uthotho wamanzi kukuba umxholo we-sodium sulfate inkulu. Xa iqondo lobushushu lingaphantsi kwe-15 ℃, i-sodium ye-sodium ye-sodium yenzekile.

 

I-2. I-Polycarboxyboxylic Acid Superplasticiezer

I-polycarboxycylic acidUmgangatho wamanzi uthathwa njengesizukulwane esitsha sokunciphisa umda wamanzi omninzi, kwaye abantu bahlala belindele ukuba kukhuseleke ngakumbi kwaye kulungelelaniswe ngakumbi ngakumbi kunomgangatho wamanzi wemveli u-Naphthalene. Izibonelelo zokusebenza zePolycarboxyylic I-Agering Arder yokunciphisa amanzi iboniswa ikakhulu kwi: I-Dosage esezantsi (0,15%), i-Slids ePhakamileyo (i-slinkis eguqulweyo), umoya ophantsi, umoya ophantsi, umoya othile Ukufakwa, kunye ne-Alkali ePhezulu kakhulu.

Nangona kunjalo, xa usenza,i-polycarboxycylic acidUkucutha amanzi kuya kudibana nezinye iingxaki, ezinjenge: 1. Iziphumo zokuncitshiswa kwamanzi zixhomekeke kwizinto eziluhlaza kwaye zixube ikhonkrithi yekhonkrithi, kwaye ichaphazeleke kakhulu ngumgangatho wesanti; 2. Ifuthe lokugqitha kwamanzi kunye neziphumo zokugcina amanzi lixhomekeke kakhulu kumthamo wokuncitshiswa kwamanzi, kwaye kunzima ukugcina ukuthambeka kwedosi ephantsi; 3. Ukusetyenziswa koxinzelelo oluphezulu okanye amandla aphezulu ekhonkrithi anexabiso elikhulu lemibuzo, enovelwano ekusebenziseni amanzi, kwaye i-dutsion encinci yokusetyenziswa kwamanzi kunokubangela utshintsho olukhulu kwi-slump; 4. Kukho ingxaki yokuhambelana nezinye iintlobo zokunciphisa amanzi kunye nezinye iziphumo, okanye akukho siphumo; 5. Ngamanye amaxesha ikhonkrithi inamandla amakhulu okopha, ukufunyanwa komoya okunzulu, kunye neebhubhu ezinkulu kunye ezininzi; I-6. Ngamanye amaxesha utshintsho lobushushu luya kuchaphazela isiphumo sei-polycarboxycylic acidUmgangatho wamanzi.

Izinto ezichaphazela ukungangqinelani kwesamente kunyei-polycarboxycylic acidUkucutha amanzi: 1. Umyinge we-C3A / C4AF kunye ne-C3S / C2S unyuka, ukuncipha kwe-COSTE, i-C3A inyuke, kunye nokusetyenziswa kwamanzi kwikhonkrithi. Xa umxholo wayo ungaphezulu kwe-8%, ukuphulukana nokutyibilika kwekhonkrithi; 2. Umxholo omkhulu kakhulu okanye omncinci kakhulu i-alkali iya kuchaphazela kakubi ukuhambelana kwabo; 3. Umgangatho olihlwempuyo wokudibana kwesamente uya kuchaphazela ukungqinelana kwezi zibini; 4. Iifom ezahlukeneyo ze-gypsum; 5. I-CEPE HEPTI YEMALI SOKUGQIBELA Inokubangela ukuseta ngokukhawuleza xa ubushushu obungaphezulu kwe-80 ℃; I-6. Isamente ecocekileyo inepropathi eyomeleleyo yombane kunye nokukwazi ukomelela ngokufumana ukunciphisa amanzi; I-7. Indawo ethile yesamente.
