qhia:
Cellulose ethers yog feem ntau siv additives nyob rau hauv kev tsim kho kev lag luam.Nws yog siv los ua thickener, stabilizer thiab binder nyob rau hauv mortar compositions.Cov yam ntxwv tshwj xeeb ntawm cellulose ethers ua rau lawv cov khoom siv zoo tshaj plaws hauv kev siv tshuaj khib nyiab.Lub hom phiaj ntawm daim ntawv no yog los tham txog kev cuam tshuam ntawm cellulose ethers ntawm cov khoom ntawm mortar thiab nws cov yam ntxwv.
Khoom nta:
Cellulose ethers yog hluavtaws polymers muab los ntawm cellulose (cov nroj tsuag teeb meem).Cov saw hlau polymer hauv cellulose ethers muaj cov pab pawg hydroxyl uas ua rau lawv tsim hydrogen bonds nrog dej molecules.Cov cuab yeej no txhim kho lub peev xwm thickening ntawm cellulose ethers hauv aqueous systems.
Cellulose ether kuj yog nonionic, uas txhais tau tias nws nqa tsis tau nqi.Qhov no txhim khu nws compatibility nrog rau lwm yam khoom nyob rau hauv lub mortar system.Cov xwm txheej uas tsis yog-ionic kuj tseem tiv thaiv kev tsim cov nqi hluav taws xob uas tuaj yeem ua rau muaj teeb meem nrog kev siv tshuaj khib nyiab.
Influence ntawm mortar zog:
Ntxiv cellulose ethers rau mortar compositions muaj ntau yam zoo.Ib qho txiaj ntsig tseem ceeb tshaj plaws yog nws lub peev xwm los txhim kho machinability.Cellulose ethers ua rau kom cov viscosity ntawm cov tshuaj khib, ua kom yooj yim rau kev thov rau saum npoo.Nws kuj tseem txhim kho cov khoom thixotropic ntawm mortar, ua kom yooj yim ntws thaum siv tab sis harden sai sai tom qab kev tsim kho.
Lwm qhov zoo dua ntawm cellulose ethers yog lawv lub peev xwm los txhim kho cov dej tuav ntawm cov tshuab mortar.Kev tuav dej yog qhov tseem ceeb rau cov tshuab mortar vim nws tso cai rau cov tshuaj khib kom kho tau zoo.Lub peev xwm ntawm cellulose ether los tsim hydrogen bonds nrog dej molecules txhim kho cov dej tuav lub peev xwm ntawm cov tshuaj khib thiab tiv thaiv cov mortar kom qhuav sai heev.
Cellulose ethers kuj tuaj yeem txhim kho cov nplaum nplaum ntawm cov tshuab mortar.Qhov nce viscosity ntawm mortar ua rau nws yooj yim rau kev ua raws li qhov chaw, thaum nws cov khoom thixotropic xyuas kom meej tias cov mortar adheres khov kho tom qab thov.Kev txhim kho cov khoom sib txuas kuj tseem txo qis qhov tshwm sim ntawm cov kab nrib pleb hauv cov kab ke.
nyob rau hauv xaus:
Hauv kev xaus, cellulose ethers yog ib qho tseem ceeb additives nyob rau hauv kev tsim kho kev lag luam.Nws cov yam ntxwv tshwj xeeb ua rau nws yog ib qho zoo tagnrho additive rau mortar compositions.Qhov sib ntxiv ntawm cellulose ethers rau mortar systems coj cov txiaj ntsig xws li kev txhim kho kev ua haujlwm, dej tuav thiab cov khoom nplaum.Cov txiaj ntsig zoo ntawm cellulose ethers ntawm cov khoom ntawm mortars tau ua rau lawv yog ib feem tseem ceeb ntawm kev tsim kho kev lag luam.
