Cellulose yog dav siv nyob rau hauv thermal rwburb master masterbatch, ntuav hmoov, asphalt txoj kev, gypsum cov khoom lag luam thiab lwm yam lag luam. Nws muaj cov yam ntxwv ntawm kev txhim kho thiab txhim kho cov ntaub ntawv hauv tsev, thiab txhim kho cov khoom siv ruaj khov ntau thiab kev tsim kho kom haum. Niaj hnub no, Kuv yuav qhia rau koj cov teeb meem tshwm sim los ntawm cellulose thaum siv putty hmoov.
(1) Tom qab cov hmoov putty yog sib xyaw nrog dej, qhov ntau nws tau starred, lub thinner nws ua.
Cellulose yog siv los ua cov tuab thiab dej-khaws cia tus neeg sawv cev hauv cov hmoov putty. Vim tias lub thixotrotropy ntawm cellulose ntawm cellulose hauv putty cov hmoov kuj ua rau thixotrotropy tom qab lub putty yog tov nrog dej. Hom ntawm thixotropy no tshwm sim los ntawm kev puas tsuaj ntawm cov qauv ua ke ntawm cov txheej txheem ntawm cov hmoov nplej rau hauv cov hmoov ua kom muaj. Cov qauv no tshwm sim thaum so thiab cais tawm hauv kev ntxhov siab.
(2) Cov zaub mov yog qhov hnyav thaum lub sijhawm ntsuas.
Qhov xwm txheej no feem ntau tshwm sim vim tias lub cellulose siv yog siab dhau. Cov lus pom zoo ntxiv rau ntawm phab ntsa sab hauv Putty yog 3-5kg, thiab viscosity yog 80,000-100,000.
(3) Lub viscosity ntawm cellulose nrog tib viscosity muaj sib txawv nyob rau lub caij ntuj no thiab lub caij ntuj sov.
Vim tias lub thermal gelation ntawm cellulose, lub viscosity ntawm lub putty thiab tshuaj khib ua yuav maj mam txo qis nrog qhov ntsuas kub. Thaum qhov ntsuas kub tshaj lub cellulose cellulose cellulose cellulose kub, lub cellulose yuav precipated los ntawm dej, yog li poob viscosity. Nws raug nquahu kom xaiv cov khoom lag luam nrog cov khoom lag luam ntau dua thaum siv cov khoom nyob rau lub caij ntuj sov, lossis xaiv cov khoom siv nrog cov khoom siv kub siab dua. Sim tsis txhob siv methyl cellulose nyob rau lub caij ntuj sov. Nyob ib ncig ntawm 55 degrees, qhov ntsuas kub me me dua, thiab nws viscosity yuav muaj cuam tshuam heev.
Txhawm rau kom suav cov hmoov, cellulose siv rau hauv cov hmoov ua kom muaj zog thiab lwm yam kev lag luam, uas tuaj yeem txhim kho fluicabity, muaj cov pa hluav taws kub, thiab ntsuab thiab ib puag ncig phooj ywg. Nws yog qhov kev xaiv zoo tshaj plaws rau peb xaiv thiab siv.
