Polycarboxylate Superplasticizer Cov Khoom Siv Dej Siab Rau Cov Cementitious Mortar
1. Cov tshuaj superplasticizers yog cov hydrodynamic surfactants (cov neeg sawv cev ntawm qhov chaw) rau kev ua haujlwm siab ntawm qhov txo qis w / c piv los ntawm kev txo qhov sib txhuam ntawm cov noob.
2. Cov tshuaj Superplasticizers, tseem hu ua cov tshuaj txo dej siab, yog cov tshuaj ntxiv rau kev ua cov pob zeb muaj zog lossis tso cov pob zeb uas sib zog. Cov tshuaj yas yog cov tshuaj sib xyaw ua ke uas ua rau cov pob zeb muaj dej tsawg dua li 15%.
3. PC seris yog ib qho Poly carboxylate polymer uas muaj zog dua thiab muaj zog dua thiab qhia txog kev sib cais thiab kev los ntshav, nws ntxiv rau kev tsim cov pob zeb ua haujlwm siab thiab ua ke nrog cement, aggregate, thiab admixture.

Sulphonated Melamine Formaldehyde (SMF) Superplasticizer rau Cov Khoom Siv Ua Vaj Tse
1. Sulphonated Melamine Formaldehyde (SMF) tseem hu ua Sulfonated Melamine Formaldehyde, Sulfonated Melamine Formaldehyde Condensate, Sodium Melamine Formaldehyde. Nws yog lwm hom superplasticizer ntxiv rau Sulphonated Naphthalene Formaldehyde thiab Polycarboxylate superplasticizer.
2. Cov tshuaj superplasticizers yog cov hydrodynamic surfactants (cov neeg sawv cev ntawm qhov chaw) rau kev ua haujlwm siab ntawm qhov txo qis w / c piv los ntawm kev txo qhov sib txhuam ntawm cov noob.
3. Raws li cov tshuaj sib xyaw ua kom dej tsawg, Sulfonated melamine formaldehyde (SMF) yog ib qho polymer siv rau hauv cov cement thiab plaster-based formulations los txo cov dej, thaum ua kom cov dej ntws thiab ua haujlwm tau zoo ntawm cov sib tov. Hauv cov concretes, ntxiv SMF rau hauv kev tsim cov sib tov tsim nyog ua rau cov porosity qis dua, lub zog kho tshuab siab dua, thiab kev tiv thaiv zoo dua rau cov chaw ib puag ncig.

Sodium Naphthalene Sulfonate Formaldehyde FDN (Na2SO4 ≤5%) rau cov khoom sib xyaw ua ke
1. Sodium naphthalene sulfonate formaldehyde FDN tseem hu ua naphthalene based superplasticizer, poly naphthalene sulfonate, sulphonated naphthalene formaldehyde. Nws cov tsos yog hmoov xim av daj. SNF superplasticizer yog ua los ntawm naphthalene, sulfuric acid, formaldehyde thiab kua hauv paus, thiab dhau los ntawm ntau yam kev tshuaj xws li sulfonation, hydrolysis, condensation thiab neutralization, thiab tom qab ntawd ziab ua hmoov.
2. Naphthalene sulfonate formaldehyde feem ntau hu ua superplasticizer rau cov pob zeb ua vaj tse, yog li nws tshwj xeeb tshaj yog rau kev npaj cov pob zeb muaj zog siab, cov pob zeb kho nrog pa dej, cov pob zeb ua kua, cov pob zeb tsis nkag tau, cov pob zeb tsis muaj dej, cov pob zeb yas, cov hlau tuav thiab cov pob zeb ua kom muaj zog. Tsis tas li ntawd, sodium naphthalene sulfonate formaldehyde kuj tseem siv tau ua cov tshuaj dispersant hauv kev lag luam tawv, textile thiab zas xim, thiab lwm yam. Ua tus kws tshaj lij tsim khoom ntawm naphthalene superplasticizer hauv Suav teb, Longou ib txwm muab cov hmoov SNF zoo thiab cov nqi Hoobkas rau txhua tus neeg siv khoom.
