Qhov txawv ntawm Plasticizer thiab Superplasticizer yog dab tsi?

Plasticizer:

A yas yasyog ib qho additive siv los txhim kho cov plasticity ntawm tej yam khoom. Cov additives no feem ntau yog siv rau hauv cov khoom siv polymer xws li PVC thiab hauv cov khoom sib xyaw ua ke los ua cov dej txo. Los ntawm kev txhim kho plasticity ntawm cov ntaub ntawv, plasticizers pab yooj yim tuav thiab siv, uas tuaj yeem ua tau zoo tshwj xeeb hauv kev tsim kho thiab kev tsim khoom.

Cov yam ntxwv tseem ceeb ntawm Plasticizers:

Kev ua haujlwm:Plasticizers txhim kho plasticity ntawm cov ntaub ntawv polymer thiab ua haujlwm ua dej hauv cov pob zeb sib tov.

Dej txo:Lawv tuaj yeem txo qhov kev xav tau ntawm dej los ntawm 5-15%, uas pab ua kom tau raws li qhov xav tau thiab kev ua haujlwm ntawm pob zeb tsis muaj kev cuam tshuam nws lub zog.

Noj ntau npaum:Feem ntau, plasticizers tau ntxiv rau hauv qhov ntau ntawm {{0}}.1 - 0.5% los ntawm qhov hnyav ntawm cov cement.

Kev sib xyaw:Plasticizers feem ntau yog raws li lignosulphonate, lub ntuj polymer muab tau los ntawm lignin, uas yog ib qho khoom los ntawm kev lag luam ntawv.

Superplasticizer:

A superplasticizeryog ib qho dej-txo admixture uas muaj peev xwm ua kom txo tau cov dej tseem ceeb los yog txhim kho cov dej ntws ntawm cov pob zeb uas tsis ua rau tsis muaj teeb meem los yog kev nkag mus ntawm huab cua. Superplasticizers tseem hu ua high-range water reducers vim lawv cov txiaj ntsig hauv kev txo cov dej.

Cov yam ntxwv tseem ceeb ntawm Superplasticizers:

Kev ua haujlwm:Superplasticizers ntxiv cov dej yuav tsum tau rau cov pob zeb sib tov, uas nyob rau hauv lem txhim khu lub zog thiab durability ntawm pob zeb.

Dej txo:Lawv tuaj yeem txo qhov kev xav tau ntawm dej mus txog 30%, tso cai rau kev tsim cov pob zeb ua haujlwm zoo nrog cov khoom siv kho tshuab zoo dua qub.

Noj ntau npaum:Superplasticizers feem ntau ntxiv rau hauv thaj tsam ntawm 0.5 - 3% los ntawm qhov hnyav ntawm cov cement.

Hom Hom:Feem ntau siv superplasticizers suav nrog Sulfonated Melamine Formaldehyde (SMF), Sulfonated Naphthalene Formaldehyde (SNF), thiab Polycarboxylate Ether (PCE).

Kev sib piv

Dej Reduction Capacity:

Plasticizerstuaj yeem txo cov ntsiab lus dej los ntawm 5-15%.

Superplasticizerstuaj yeem txo cov dej ntau txog 30%.

Noj ntau npaum:

Plasticizersntxiv ntawm {{0}}.1 - 0.5% los ntawm qhov hnyav ntawm cov cement.

Superplasticizersntxiv ntawm 0.5 - 3% los ntawm qhov hnyav ntawm cov cement.

Kev cuam tshuam rau pob zeb:

Plasticizerstxhim khu lub plasticity thiab workability ntawm pob zeb nrog cov dej txo qis.

Superplasticizersmuab qhov tseem ceeb txo cov dej thiab txhim kho cov flowability, lub zog, thiab durability ntawm pob zeb.

Tshuaj muaj pes tsawg leeg:

PlasticizersFeem ntau yog raws li lignosulphonate.

Superplasticizerssuav nrog cov tebchaw siab heev xws li SMF, SNF, thiab PCE.

Daim ntawv thov

Plasticizersfeem ntau yog siv rau hauv cov ntawv thov uas muaj kev txhim kho me ntsis hauv plasticity thiab txo dej kom txaus. Lawv muaj nyob rau hauv cov qauv kev tsim kho thiab tsim cov khoom siv polymer.

Superplasticizers, ntawm qhov tod tes, yog siv rau hauv cov ntawv thov ntau dua qhov yuav tsum muaj kev ua haujlwm siab dua. Qhov no suav nrog cov tsev siab siab, txuas hniav, thiab lwm yam kev tsim kho vaj tse uas txhim kho lub zog, durability, thiab flowability tseem ceeb heev.

Hauv kev xaus, thaum ob qho tib si plasticizers thiab superplasticizers pab txo cov ntsiab lus dej thiab txhim kho kev ua haujlwm ntawm cov pob zeb, superplasticizers muab cov dej ntau dua thiab kev txhim kho kev ua tau zoo, ua rau lawv tsim nyog rau kev siv tshwj xeeb thiab xav tau kev tsim kho.
