Ib qho me me ntawm hydroxypropyl methylcellulose ether ua rau cov dej nyob hauv lub mortar kom txaus rau lub sijhawm los txhawb kev ua kom cov cement noo tas mus li thiab txhim kho qhov kev sib txuas ntawm lub mortar thiab lub substrate.
Cov Nyhuv ntawm Qhov Loj ntawm Cov Khoom Me Me thiab Lub Sijhawm Sib Tov ntawm Hydroxypropyl Methyl Cellulose Ether ntawm Kev Khaws Dej
Lub peev xwm khaws dej ntawm cov mortar feem ntau yog tswj los ntawm lub sijhawm yaj, thiab cov cellulose me dua yaj sai dua, thiab lub peev xwm khaws dej sai dua. Rau kev tsim kho tshuab, vim muaj kev txwv sijhawm, kev xaiv cov cellulose yuav tsum yog hmoov zoo dua. Rau kev pleev tes, hmoov zoo yuav ua tau.
Cov Nyhuv ntawm Etherification Degree thiab Kub ntawm Hydroxypropyl Methyl Cellulose Ether ntawm Kev Khaws Dej
Qhov solubility thiab kub ntawm hydroxypropyl methylcellulose hauv dej nyob ntawm qib ntawm etherification. Thaum qhov kub sab nraud nce siab, qhov kev khaws cia dej txo qis; qhov siab dua ntawm etherification, qhov zoo dua qhov kev khaws cia dej ntawm cellulose ether.
Cov nyhuv ntawm hydroxypropyl methylcellulose ether rau ntawm qhov sib xws thiab kev tiv thaiv kev plam ntawm cov mortar
Qhov sib xws thiab cov khoom tiv thaiv kev swb ntawm cov mortar yog cov cim qhia tseem ceeb heev, ob qho tib si rau kev tsim cov txheej tuab thiab cov nplaum pobzeb xav tau qhov sib xws thiab cov khoom tiv thaiv kev swb.
Txoj kev sim kev sib xws, txiav txim siab raws li tus qauv JG / J70-2009
Qhov sib xws thiab kev tiv thaiv kev plam feem ntau yog pom los ntawm qhov viscosity thiab qhov loj ntawm cov khoom me me ntawm hydroxypropyl methylcellulose. Nrog rau qhov nce ntawm viscosity thiab cov ntsiab lus, qhov sib xws ntawm cov mortar nce ntxiv; qhov me me ntawm cov khoom me me, qhov siab dua qhov pib sib xws ntawm cov mortar sib xyaw tshiab. sai.
Cov nyhuv ntawm Hydroxypropyl Methyl Cellulose rau cua nkag ntawm Mortar
Vim yog qhov ntxiv ntawm hydroxypropyl methylcellulose rau hauv cov mortar, qee qhov me me, sib xws thiab ruaj khov cua npuas tau nkag mus rau hauv cov mortar sib xyaw tshiab. Vim yog lub pob nyhuv, cov mortar muaj kev tsim kho zoo thiab txo qhov shrinkage thiab torsion ntawm cov mortar. Nroj tsuag tawg, thiab ua rau cov zis tawm ntawm cov mortar. Cellulose muaj lub luag haujlwm cua-entraining. Thaum ntxiv cellulose, xav txog qhov ntau npaum li cas, viscosity (viscosity siab dhau yuav cuam tshuam rau kev ua haujlwm), thiab cov khoom cua-entraining. Xaiv cellulose rau ntau hom mortars.
