Taariikhda Boostada: 9, May, 2022

(一) Laqabsashadapolycarxurdylate superplastizer iyo agabyada loo yaqaan:

Ficil ahaan, waa la helay taasPolycarxurdylate superplastizerDhibaatooyinka laqabsashada ee muuqata ee laqabsashada ee laqabsashada waafaqsanaanta kaladuwan iyo noocyada kala duwan ee macdanta macdanta, mararka qaarkoodna xitaa waa kuwo aad u qurux badan. La qabsiga u dhexeeya sibidhka iyopolycarxurdylate superplastizer waxaa saameyn ku yeelan doonta arrimo badan. Sida: Qaybaha sibidhka, aagga dusha gaarka ah, alkali nuxurka, waxa ku jira gypsum iyo noocyo ayaa dhammaantood saameyn ku leh laqabsashadaPolycarxurdylate superplastizer.

Barta buurta eePolycarxurdylate superplastizerWixii loogu talagalay GRESS-ka kala duwan way ka duwan yihiin, heerka yareynta biyaha waa la yareeyaa, oo ah mid ka mid ah hoos udhaca la taaban karo, ayaa soo ifbaxaya marka la taaban karo, iyo dhibaatooyinka dhiig-baxa, iyo kala-goynta, iyo bamgareynta. , U nugul qiyaasta daawada, la taaban karo lama furi karo ama si xad dhaaf ah looma sii deyn karo. Tusaale ahaan, waxa ku jirapolycarxurdylate superplastizer Sibidhku waa 1.8% (waxa adag ee 10%) si loo helo dowlad lagu qanco, halka B sibidhka loo baahan yahay in lagu qaso 2.2% si ay u dhaafto dowlad wanaagsan, iyo marmarka qaarkood marka ay ka badan tahay 2.2% isku dhafka ah. wuxuu u nugul yahay dhiig baxa.

Waqtiga xaadirka ah, marka la eego la-qabsiga eePolycarxurdylate superplastizer, xalka waa sida soo socota:

(1) on hubinta hubinta xoogga la taaban karo, adoo laqabanaya heerka ciidda, saamiga cabirka ee isku-darka isku-darka, iyo kordhinta tirada nidaamka la taaban karo;

(2) Khamriga hooyadu waxay ku qasban tahay bushimaha ether ah oo qiyaasta si ku habboon ayaa loo kordhiyaa. Guud ahaan, waxaa lagula talinayaa in shaqa-yarada iyo lihisyada 5: 5 ay saameyn wanaagsan yeeshaan, oo qiyaasta daawada waa in lagu kordhiyaa 0.2%;

(3) si ku habboon wax ku dadasho ama beddelo qaybahaas, isticmaal wakiilo ka mid ah dadka-galinta sida SJ, Despium-ka Foomphat Ar, sonkorta, fosfooraska, fosfooraska, atmp acid, atmp acid, Isboortiga wax laga beddelay iyo dib-u-dhiska kale ee isku-dhafka ah, iyadoo la adeegsanayo blulolose keli-ka, xaynthan xanjo, dextrin, wax laga beddelay dhumuc weyn, ama ku darista "sulfur" ama "alkali" si loo fidiyo waa la hagaajin karaa;

(4) Beddel qaab dhismeedka molikalka ee polycarxylacylic, oo ku hagaaji qaybaha qaarkood geedi socodka isku-darka si loo waafajiyo laqabsashada.

Waxyaabaha loo qariyo, saameynta ash duulista ayaa si cad uga weyn tan budada slag. Guud ahaan hadalka, ash-data darajada koowaad waxay leedahay laqabsasho wanaagsan, halka ash-data damac labaad iyo saddexaad uu u nugul yahay tababbaynta, gaar ahaan ash-da-data darajada saddexaad. Marka tayada ashtarka ay liidato, saamaynta kordhinta qiyaasta qiyaastapolycarxurdylate superplastizerWaqtigaas wali si weyn looma fiicnaan karo. Sababta ugu weyn ee ifafaale this waa in ash-ka ka hortaga sare iyo matoorku ay ku baxaan, iyo awoodda xayeysiinta ee walxaha dabka ka sareeya ay u weyn yihiin, taasoo yareynaysa xayeysiinta admadka, oo saamaynaya dareenka la taaban karo. Markaad isticmaaleyso Fasalka III, kordhinta waxa ku jira yareynta biyaha polycarxuylate in ka badan 50%, si loo gaaro heerka yareynta biyaha marka lagu daro fasalka mid duulaya. Marka laga hadlayo dambaska ash ee duulaya oo leh tayo tayo adag leh iyo qaybo kaladuwan, waxaa lagama maarmaan ah, waxaa lagama maarmaan ah in la xoojiyo xakameynta tayada ee ashyada duulimaadka iyo xoojinta imtixaanka polycarxurdylate superplastizer.
