Ua phab ntsa putty nrog KimaCell HPMC
Ua phab ntsa putty nrog KimaCell HPMC (Hydroxypropyl Methylcellulose) koom nrog kev sib txuas ntawm HPMC nrog lwm cov khoom xyaw kom ua tiav cov khoom xav tau xws li adhesion, workability, thiab dej tsis kam. Nov yog daim ntawv qhia yooj yim rau kev ua phab ntsa putty siv KimaCell HPMC:
Cov khoom xyaw:
- KimaCell HPMC (Hydroxypropyl Methylcellulose)
- Dawb cement
- Fine xuab zeb (silica xuab zeb)
- Calcium carbonate (yeem, rau muab tub lim)
- Dej
- Plasticizer (yeem, txhawm rau txhim kho kev ua haujlwm)
Cov lus qhia:
- Npaj cov tshuaj HPMC:
- Dissolve qhov xav tau ntawm KimaCell HPMC hmoov hauv dej. Feem ntau, HPMC yog ntxiv ntawm qhov concentration ntawm ib ncig ntawm 0.2% mus rau 0.5% los ntawm qhov hnyav ntawm tag nrho cov khoom xyaw qhuav. Kho qhov concentration raws li qhov xav tau viscosity thiab workability ntawm putty.
- Sib tov cov khoom xyaw qhuav:
- Hauv ib lub thawv cais, sib tov cov cement dawb, xuab zeb zoo, thiab calcium carbonate (yog siv) hauv qhov xav tau. Qhov tseeb piv yuav txawv nyob ntawm seb qhov yuav tsum tau ua ntawm daim ntawv thov, tab sis ib qho piv txwv yog nyob ib ncig ntawm 1 feem cement rau 2-3 seem xuab zeb.
- Muab cov khoom xyaw ntub thiab qhuav:
- Maj mam ntxiv cov tshuaj HPMC rau qhov sib tov qhuav thaum sib tov kom huv si. Xyuas kom meej tias cov tshuaj HPMC sib npaug sib npaug thoob plaws qhov sib xyaw kom ua tiav qhov sib xws thiab adhesion.
- Kho qhov sib xws:
- Nyob ntawm qhov xav tau sib xws thiab kev ua haujlwm ntawm putty, koj yuav tsum tau ntxiv dej ntxiv los yog plasticizer rau qhov sib tov. Ntxiv me me dej los yog plasticizer rau ib lub sij hawm thiab sib tov kom huv si kom txog thaum qhov kev xav tau sib xws.
- Kev sib xyaw thiab ruaj khov:
- Txuas ntxiv sib tov lub putty kom txog thaum nws ncav cuag ib tug du thiab zoo nkauj zoo nkauj. Tsis txhob overmixing, vim qhov no tuaj yeem cuam tshuam kev ua haujlwm ntawm putty.
- Thaum sib tov, cov phab ntsa putty tuaj yeem siv tam sim ntawd lossis khaws cia rau hauv lub thawv kaw kom tsis txhob ziab tawm. Yog tias khaws cia, xyuas kom meej tias lub putty tiv thaiv los ntawm ya raws thiab kab mob.
- Daim ntawv thov:
- Siv cov phab ntsa putty rau qhov chaw npaj siv lub trowel los yog putty riam. Xyuas kom meej tias qhov chaw huv si, qhuav, thiab tsis muaj plua plav lossis khib nyiab ua ntej thov.
- Smooth lub putty sib npaug ntawm qhov chaw, ua haujlwm hauv cov ntu me me ntawm ib lub sijhawm. Cia lub putty kom qhuav tag ua ntej xuab zeb lossis pleev xim, ua raws li cov chaw tsim khoom cov lus qhia rau lub sijhawm ziab.
Daim ntawv qhia yooj yim no tuaj yeem hloov kho raws li cov kev cai tshwj xeeb, xws li qhov xav tau thickness, adhesion, thiab kev ntxhib los mos ntawm phab ntsa putty. Kev sim nrog ntau qhov sib txawv thiab cov khoom ntxiv los kho cov putty rau koj qhov kev nyiam thiab daim ntawv thov xav tau. Tsis tas li ntawd, ib txwm ua raws li kev ceev faj txog kev nyab xeeb thiab cov chaw tsim khoom cov lus qhia thaum tuav thiab siv HPMC thiab lwm yam khoom siv.
