Ash calcium powder, heavy calcium powder (kana gypsum powder), uye cellulose ndizvo zvinhu zvikuru zvinoumba putty powder.
Basa re ash calcium powder mu putty nderokuvandudza kushanda kwechigadzirwa, kusanganisira kuvandudza simba, kuoma, kushorwa kwemvura kweputty powder chigadzirwa, uye kushanda kwekutsvaira nekukuya panguva yekuvaka. Heavy calcium powder inoshandiswa sekuzadza kuderedza mari yekugadzira, uye cellulose inoita basa mukuchengetedza mvura. , kubatana uye mamwe mabasa.
Mukugadzirwa kweputty powder, kupupa idambudziko rinowanzoitika. Chii chinozvikonzera?
Ash calcium powder (chikamu chikuru icalcium hydroxide, inova chigadzirwa chakanatswa cheraimu), heavy calcium powder (chikamu chikuru icalcium carbonate, inova calcium carbonate stone powder yakananga pasi kubva pacalcium carbonate stone) kazhinji haizokonzeri putty powder. kutsemuka mushure mekushandisa. bubble phenomenon.
chikonzero chekuputika
Zvikonzero zvikuru zvekupupa kweputty powder ndezvizvi:
1. Nheyo yepasi yakanyanya kushata ine maburi madiki. Paunenge uchikwenya, iyo putty inomanikidza mhepo mugomba, uye ipapo mhepo yemhepo inodzokera kunogadzira mabubble emhepo.
2. Iyo imwe-pass scraping yakanyanyisa, uye mhepo iri mumapores eputty haina kudzvinyirirwa kunze.
3. Chigadziko chepasi chakanyanya kuoma uye mwero wekunyudzwa kwemvura wakanyanya, izvo zvinokonzeresa mabhuru emhepo mupete layer putty.
4. Pendi inodzivirira mvura, kongiri yepamusoro uye zvimwe zvigadziko zvine mhepo yakanaka zvinokonzeresa kuputika.
5. Putty inowanzoita mabhubhu panguva yekuvakwa kwekushisa kwepamusoro.
. yakaoma, kuitira kuti mabhuru emhepo asava nyore kudzvinyirirwa kunze ne trowel, zvichiita kuti pinholes Pores ndicho chikonzero nei kune mamwe mabhuru emhepo pamusoro pe scraped formwork pane pamadziro muinjiniya. Kunyura kwemvura kwemadziro kwakakura, asi kunyura kwemvura kweformwork top kwakadzikira zvakanyanya.
7. Iyo viscosity ye cellulose yakanyanya kukwirira.
