Khoom Description
Thaum RDP sib xyaw nrog dej, nws sai sai tau tshaj tawm sib npaug thiab tsim cov emulsion ruaj khov. Qhov no emulsion yog ib qho yooj yim heev los thov rau ntawm ib qho chaw tiaj tus.
RDP muaj ntau tus yam ntxwv tshwj xeeb uas ua rau nws yog qhov saum toj kawg nkaus - kev xaiv ntawm cov engineers tsim thiab tsim thoob plaws ntiaj teb. Muaj ntau qhov sib txawv ntawm kev siv cov khoom siv rov ua dua tshiab polymer uas tsis sib xws nrog lwm cov khoom siv.
Kev siv RDP hauv kev tsim kho cov haujlwm yog pom zoo kom ua kom muaj qhov zoo ntawm cov khoom siv. Kev sib xyaw RDP hauv cov khoom siv sib xyaw ua kom cov khoom sib xyaw ua kom muaj zog, yoog raws, thiab cov khoom nplaum. Qhov no pab txhim kho tag nrho cov kev ua tau zoo ntawm kev tsim vaj tse, thiab ua kom muaj zog, ruaj khov dua.
Kev ceev faj rau kev siv
1. Siv tag nrho cov khoom ntawm RDP hauv ib pob. Koj tuaj yeem ntsuas cov khoom hauv cov khoom siv, xws li thiab thaum koj xav tau ntxiv rau hauv cov tshuaj khib lossis cov cement sib tov.
2. Nco ntsoov kom tawg PP fibers hauv cov cement ua ntej. Qhov no yog vim qhov zoo ntawm cov cement pab tshem tawm hluav taws xob zoo li qub los ntawm cov fibers. Nrog rau qhov no, nws yooj yim dua kom cia cov PP fibers tau tawg tag nrho.
3. Nco ntsoov do RDP- sib tov kom huv si. Txawm li cas los xij, cov txheej txheem stirring yuav tsum tsis txhob ntev. Raws li cov kws tshaj lij kev tsim kho, RDP yuav tsum sib tov rau qhov siab kawg ntawm 15 feeb. Tsis tas li ntawd, kev sib xyaw cov cement thiab xuab zeb rau lub sijhawm ntev tuaj yeem ua rau RDP precipitate rov qab mus rau nws daim ntawv qub thiab ua stratified.
4. Kev siv RDP kom zoo yuav tsum tau kho cov tshuaj mortar additives, thiab ntxiv cov nqi ntawm HPMC, raws li lub caij nyoog.
5. Nco ntsoov zam cov cement lossis cov khoom ntxiv los ntawm kev ua kom tawv thiab clumping los ntawm kev puas tsuaj los ntawm ya raws.
6. Tsis txhob siv cov tshuaj respersible polymer hmoov, sib tov, los yog muab ntim nrog cov tshuaj acidic.
7. Tsis txhob siv RDP rau kev tsim kho hauv huab cua qis dua 5 degrees Celsius, vim nws tuaj yeem ua rau muaj kev puas tsuaj loj rau qhov ua tiav zoo. Nws tuaj yeem ua rau lub plastering mortar thiab lub rwb thaiv tsev board tsis txaus adhesion.
