Phulusa la ufa wa calcium, heavy calcium powder (kapena gypsum powder), ndi cellulose ndizinthu zazikulu zomwe zimapanga putty powder.
Ntchito ya ufa wa phulusa la calcium mu putty ndikupititsa patsogolo ntchito ya mankhwalawa, kuphatikizapo kupititsa patsogolo mphamvu, kuuma, kukana madzi kwa mankhwala a putty powder, ndi ntchito ya kukanda ndi kugaya panthawi yomanga. Heavy calcium powder amagwiritsidwa ntchito ngati chodzaza kuti achepetse ndalama zopangira, ndipo cellulose imathandizira kusunga madzi. , mgwirizano ndi ntchito zina.
Popanga putty powder, kuchita thovu ndi vuto lodziwika bwino. Kodi chimayambitsa chiyani?
Phulusa la ufa wa calcium (chinthu chachikulu ndi calcium hydroxide, chomwe ndi chopangidwa ndi laimu woyengedwa), heavy calcium powder (chigawo chachikulu ndi calcium carbonate, chomwe ndi ufa wa miyala wa calcium carbonate womwe umachokera ku mwala wa calcium carbonate) nthawi zambiri sungayambitse putty powder. kusweka pambuyo pa ntchito. kuwira chodabwitsa.
chifukwa cha matuza
Zifukwa zazikulu zopangira thovu la putty powder ndi izi:
1. Chigawo chapansi ndi chovuta kwambiri chokhala ndi mabowo ang'onoang'ono. Mukakolora, putty amapondereza mpweya mu dzenje, ndiyeno kuthamanga kwa mpweya kumabwereranso kupanga thovu la mpweya.
2. Kukwapula kwa single-pass ndi wandiweyani kwambiri, ndipo mpweya wa pores wa putty sunafinyidwe.
3. Chosanjikiza chapansi chimakhala chouma kwambiri ndipo kuchuluka kwa mayamwidwe amadzi ndikokwera kwambiri, zomwe zingapangitse kuti mpweya wambiri ukhale wochuluka pa putty.
4. Utoto wosamva madzi, konkriti wapamwamba kwambiri ndi malo ena oyambira okhala ndi mpweya wabwino amatha kuyambitsa matuza.
5. Putty sachedwa thovu pomanga kutentha kwambiri.
6. Mayamwidwe amadzi azinthu zoyambira ndi otsika kwambiri, zomwe zimapangitsa kuti nthawi yosungira madzi ya putty ndi yayitali kwambiri ikaphwanyidwa, kotero kuti putty amakhalabe pakhoma kwa nthawi yayitali ndipo samatero. youma, kotero kuti thovu mpweya si zophweka kufinyidwa ndi trowel, chifukwa pinholes Pores ndi chifukwa chake pali thovu mpweya pamwamba pa formwork scraped kuposa khoma mu engineering. Mayamwidwe amadzi a khoma ndiakulu, koma mayamwidwe amadzi a formwork pamwamba ndi otsika kwambiri.
7. Kukhuthala kwa cellulose ndikokwera kwambiri.
