Starch ether hauv cug

Starch Ether thicken lub cug, nce cov sag tiv, sag tsis kam, sag tsis kam thiab rheology ntawm lub tshuaj khib

Piv txwv li, hauv kev tsim cov vais nplaum, muab cov tshuaj nplaum, tshwj xeeb tshaj yog tam sim no, nws tseem ceeb heev

Cov kua thiab sag tiv taus feem ntau cuam tshuam, thiab kev nce hauv lub cev yuav coj txog kev poob qis hauv sag tsis kam. Cov tshuaj khib nrog cov khoom sib xyaw tuaj yeem daws tau qhov kev tsis sib haum xeeb, uas ua rau lub zog sab nraud, thiab thaum viscosity nce ntxiv.

Rau cov txheej txheem tam sim no ntawm thaj chaw nce ntxiv, ntxiv cov hmoov txhuv nplej siab ether tuaj yeem txhim kho lub pob zeb tsis kam ntawm cov nplais nplaum.

2) Sijhawm Qhib Sijhawm

Rau cov nplaum nplaum, nws tuaj yeem ua kom tau raws li cov vile tshwj xeeb nrog kev qhib ncua sijhawm (chav kawm e, txuas mus txog 20min mus txog 0.5mpa).

a. Kev Txhim Kho Kev Ua Haujlwm Nto

Starch ether tuaj yeem ua rau ntawm gypsum-raws thiab cenp cug du, yooj yim mus thov, thiab muaj cov nyhuv zoo nkauj. Nws yog qhov tseem ceeb rau qhov tseem ceeb rau cov ntsiab lus plaster-bied mortars thiab nyias txheej hniav zoo nkauj mortars xws li putty.

b. Cov tshuab ntawm kev ua ntawm starch ether

Thaum cov hmoov txhuv nplej siab ether yog yaj hauv dej, nws yuav tsum ua rau lub ceg xis collation. Vim tias cov hmoov txhuv nplej siab ither molecules muaj tus qauv network, yog li muab cov khoom siv hloov pauv tau zoo, uas tuaj yeem txhim kho cov kab mob los ntawm kev tawm tsam lossis kev tawm tsam cov nyhuv los tiv thaiv.
