Waafaqidpolycarboxylate superplasticizeroo leh waxyaabo kale

polycarboxylate superplasticizeriyo qaar badan oo superplasticizers ah lama isku dari karo oo laguma dari karo saami kasta sida naphthalene iyo aliphatic superplasticizers. Tusaale ahaan, saamaynta xun ee ku-haynta balaastigga ah ayaa ah tan ugu weyn marka polycarboxylic acid iyo naphthalene biyo-yaraha la isku daro, waana in fiiro gaar ah la bixiyaa. Tani waxay sidoo kale keentay in badan oo soo saarayaasha biyaha yareeya polycarboxylate si ay u farsameeyaan khamriga hooyada leh hawlo kala duwan oo gaar ah sida haynta slump iyo xoogga hore si ay ula qabsadaan baahiyaha dhismaha la taaban karo ee xilliyada kala duwan, qalabka iyo saamiga isku dhafan, iyo ugu dambeyntii lagu gaaro natiijooyin lagu qanco. Si kastaba ha ahaatee, isku dhafka iyo codsiga la taaban karo ee khamriga hooyadu waxay u baahan tahay wakhti, iyo hal nooc oo khamriga hooyada ah ma xallin karo dhibaatooyin badan oo ku saabsan codsiga injineernimada ee superplasticizers. Waa kaab lagama maarmaan u ah codsigapolycarboxylate superplasticizer, oo aad bay muhiim u tahay in la xalliyo dhibaatooyinka farsamo ee soo wajaha goobta injineernimada iyada oo loo marayo sifooyinka khamriga hooyada iyo nidaamka isku-dhafka jirka ee alaabta yaryar. Waxaa lagu talinayaa in la isticmaalopolycarboxylate superplasticizermarka lagu daro qaybaha kale. Hubi inaad xaqiijiso saamaynta isku-darka iyo saamaynta dhabta ah ee la taaban karo iyada oo loo marayo tijaabooyinka, ka dibna xukuntay in aypolycarboxylate superplasticizerwaxaa lagu dari karaa qaybo kale.

Dhibaatada caaryada kaydintapolycarboxylate superplasticizer

Markapolycarboxylate superplasticizerwaxaa lagu kaydiyaa xilliga heerkulka sare ee xagaaga, ifafaale caariyaysi ah sida soo daynta urta xun, bararka fuustooyinka baakadaha la xidhay, dhibcooyinka sabbaynaya dusha dareeraha ah ee haanta kaydinta furan, iyo walxaha sabbaynaya qaabka xariijinta ayaa badanaa dhaca. Sababta ugu weyn ayaa ah in habka oo dhan eepolycarboxylate superplasticizerlaga bilaabo wax soo saarka ilaa codsiga iyo isticmaalka ayaa lagu hayaa xaalad bakteeriyada dabiiciga ah, halka qaybaha dib u dhigista sida caadiga ah loo isticmaalo sida sonkorta iyo hydroxycarboxylates ay bixiyaan fungi. Nafaqooyinka aad u fiican, deegaanka heerkulka ku habboon iyo qoyaanka iyo pH dhexdhexaad ah, tirada fangaska ayaa si aad ah u kordheysa. Ka dib marka ay dhintaan fangaska, tiro badan oo meyd ah ayaa ka tagaya, taas oo ah sababta asalka u ah caaradapolycarboxylate superplasticizer. Sidaa darteed, maaddooyinka firfircoon ee ku jira caariyaysipolycarboxylate superplasticizersi weyn looma saameeyo, iyo waxqabadka codsigu waa mid deggan.

caariyaysipolycarboxylate superplasticizerwaxay leedahay ur xoog badan iyo xumbo badan oo dusha sare ah, taas oo aan ku habboonayn caafimaadka shaqaalaha iyo cabbirka saxda ah ee superplasticizer. Waa lagama maarmaan in la qaado tallaabooyin lagu cabudhinayo. Waxaa ka mid ah, habka ugu waxtarka badan waa in la isku daro bakteeriyada si loo gaaro saameynta bacteriostasis iyo sterilization. Isla mar ahaantaana, hababka sida hagaajinta pH ee wakiilka biyaha dhimaya si aan dhexdhexaad ahayn (pH≤3. ama pH> 9.0) iyo bedelida nooca dib u dhigista ayaa sidoo kale la isticmaali karaa.
