Kev Taw Qhia Rau Cov Yam Ntxim Saib Ntxim Ua ntawm xya yam sib txawv ntawm cov dej txo tus neeg sawv cev Monomers

Kev taw qhia txog cov yam ntxwv ntawm xya ntau hom dej txo tus neeg sawv cev monomers
Polycarboxylate high-performance dej-txo tus neeg saib xyuas yog ntau yam high-molecular organic tebchaw nrog polycarboxylate ua lub ntsiab lub cev, uas yog tsim los ntawm graft copolymerization. Nws muaj zog txo cov dej ua tau zoo thiab yog hom ntsuab thiab ib puag ncig tus phooj ywg nrog cov cuab yeej siv siab hauv ntiaj teb niaj hnub no. Kev sib xyaw ua ke. Dav siv nyob rau hauv high-speed railways, nuclear fais fab nroj tsuag, kev txuag dej thiab hydropower tej yaam num, subways, loj choj, expressways, chaw nres nkoj terminals thiab ntau yam kev lag luam thiab pej xeem kev tsim kho tej yaam num.
Polycarboxylate superplasticizer macromonomer yog ib qho tseem ceeb raw khoom nyob rau hauv synthesis ntawm polycarboxylate superplasticizer niam cawv. Av nkos, anti-alkali, antifreeze thiab lwm yam khoom sib txawv.

1. Dej-txo monomer SPEG2400

Khoom piav qhia:

Isobutenol polyoxyethylene ether yog npaj los ntawm isobutenol ua tus thawj coj, nrog cov txheeb ze molecular hnyav ntawm 2400, thiab yog ib qho tseem ceeb raw khoom rau dej-txo polycarboxylate superplasticizers. Cov khoom no tau dhau los ua cov dawb radical pib copolymerization nrog cov khoom uas muaj ob daim ntawv cog lus (xws li acrylic acid, acrylate, thiab lwm yam) raws li cov pawg hydrophilic los tsim cov copolymer, txhim kho hydrophilicity, thiab txhim kho cov dispersibility ntawm polymers hauv dej.
Nta:

Cov khoom yog ntim rau hauv hnab, haum rau nruab nrab thiab ntev kev thauj mus los; leej niam cawv ua los ntawm cov khoom no muaj cov khoom ntawm cov dej txo qis, tsawg npaum li cas, dav adaptability, tsawg shrinkage tus nqi thiab zoo durability.
2. Dej-txo monomer dej tus neeg sawv cev SPEG-60

Khoom piav qhia:

Isobutenol polyoxyethylene ether aqueous tus neeg sawv cev yog npaj los ntawm isobutenol ua tus pib; Cov ntsiab lus ntawm cov khoom yog 60 feem pua, thiab nws yog ib qho tseem ceeb raw khoom rau dej-txo polycarboxylate superplasticizers. Cov khoom no tau dhau los ua cov dawb radical pib copolymerization nrog cov khoom uas muaj ob daim ntawv cog lus (xws li acrylic acid, acrylate, thiab lwm yam) raws li cov pawg hydrophilic los tsim cov copolymer, txhim kho hydrophilicity, thiab txhim kho cov dispersibility ntawm polymers hauv dej.
Nta:

Cov khoom yog thauj los ntawm lub tank tsheb, uas yooj yim rau kev thauj mus los luv luv, thiab cov cuab yeej ntawm cov tshuaj aqueous yog ruaj khov; leej niam cawv ua los ntawm cov khoom no muaj cov khoom ntawm cov dej txo qis, tsawg npaum li cas, dav adaptability, tsawg shrinkage tus nqi thiab zoo durability.

3. Slump pov thawj monomer TPEG2400

Khoom piav qhia:

Prenyl cawv polyoxyethylene ether, uas yog npaj los ntawm imported isopentyl cawv raws li ib tug pib, muaj ib tug txheeb ze molecular luj ntawm 2400, thiab yog ib qho tseem ceeb raw khoom rau slump-retaining polycarboxylate superplasticizers. Cov khoom no tau dhau los ua cov dawb radical pib copolymerization nrog cov khoom uas muaj ob daim ntawv cog lus (xws li acrylic acid, acrylate, thiab lwm yam) raws li cov pawg hydrophilic los tsim cov copolymer, txhim kho hydrophilicity, thiab txhim kho cov dispersibility ntawm polymers hauv dej.
Nta:

Cov khoom yog ntim rau hauv hnab, haum rau nruab nrab thiab ntev kev thauj mus los; leej niam cawv uas tsim los ntawm cov khoom no muaj cov khoom ntawm kev ruaj khov siab, tsis muaj ntau npaum li cas, dav adaptability, tsawg shrinkage tus nqi, thiab zoo durability;
