BS01 Dej Retainer

Dej Retainers (tseem hu ua dej- khaws cov tshuaj lossis cov khoom sib xyaw) nyob rau hauv cov ntsiab lus ntawm cov pob zeb thiab mortar, raws li kev lag luam thiab cov ntaub ntawv kev kawm.

Cov khoom no txawv ntawm cov cellulose uas nquag siv, dextrin thiab lwm yam dej- khaws cov khoom viscosity ntawm lub khw, muaj kev sib raug zoo, thiab polycarboxylate superplasticizer tuaj yeem sib tov soluble, siv tau yooj yim thiab muaj peev xwm tuav tau ntev -lub sij hawm stability.

Cov khoom adsorbs dej ntau dhau los ntawm cov qauv molecular siab thiab tsim qhov chaw sib cuam tshuam mesh qauv, uas txhim kho kev sib raug zoo ntawm cov pob zeb thiab txo cov rhiab heev ntawm polycarboxylate superplasticizer rau cov khoom siv raw, dej siv thiab ntau npaum li cas.

Cov khoom no tseem tuaj yeem daws qhov teeb meem ntawm cov nplaum nplaum, hauv qab xaiv thiab cov dej tsis zoo ntawm cov khoom lag luam qib siab.

Nta:

1.Cov dej tuav tau zoo, tuaj yeem txhim kho kev sib koom ua ke ntawm pob zeb.

2.Low rhiab heev thiab stability, zoo meej daws teeb meem ntawm mechanism xuab zeb pob zeb.

3.Mutually soluble nrog polycarboxylate superplasticizer, nrog dej solubility thiab adaptability.

4.Nws tuaj yeem tswj cov dej tso tawm kom zoo, txhim kho qhov yooj yim thiab fluidity ntawm pob zeb.

Daim ntawv thov

Cov khoom tuav dej muaj txiaj ntsig tshwj xeeb hauv cov xwm txheej uas dej poob yog qhov kev txhawj xeeb loj:

Pumped Concrete: Txhawm rau tswj kev ua haujlwm tau zoo thiab tiv thaiv kev thaiv thaum lub sijhawm siv.

Npaj kom txhij-Kub sib xyaw: Los tswj kev poob qis thaum thauj thiab tso, tshwj xeeb tshaj yog thaum huab cua kub .

Tus kheej-Txhim kho thiab kho mortars: Txhawm rau kom muaj dej txaus thiab adhesion ntawm absorbent substrates.

Qhob nrog Manufactured Sand: Txhawm rau them nyiaj rau cov dej tsis zoo tuav thiab cohesiveness feem ntau tshwm sim los ntawm qhov tsis sib xws thiab cov ntsiab lus nplua nuj ntawm cov xuab zeb tsim.

Doping:

Hauv cov dej txo tus neeg sawv cev hauv cov khoom tiav ntau npaum li cas ntawm 0.2% -1.5%, naphthalene aliphatic 0.1% -0.5% lossis tsawg dua, raws li kev siv cov kev xav tau thiab kev siv cov txiaj ntsig los ntawm kev sim los txiav txim siab npaum li cas.

Ntim thiab khaws cia tseem ceeb:

1.Cov khoom no tsis yog - tshuaj lom, tsis yog - corrosive, tsis muaj kuab paug rau ib puag ncig, khaws cia rau hauv qhov chaw txias.

2.Cov khoom no tau ntim rau hauv 200KG yas nruas los yog thauj los ntawm bulk tanker.

Dej Retainer yog ib qho tseem ceeb rau kev tswj cov rheology thiab hydration ntawm cementitious systems. Nws tiv thaiv kev sib cais, tswj kev ua haujlwm, thiab thaum kawg ua rau lub zog thiab ua haujlwm ntawm cov pob zeb tawv tawv lossis mortar. Qhov kev xaiv ntawm cov khoom tuav dej yog nyob ntawm daim ntawv thov tshwj xeeb, hom kev khi, thiab cov yam ntxwv uas xav tau.
