1. Redispersible latex poda
Ichi chinodiridza muromo chinhu chakakosha chepamusoro molecular polymer, inogadzirwa kuita hupfu mushure mekupfapfaidza kuoma. Mushure mekusangana nemvura, hupfu uhu hunogona kuva emulsion zvakare, uye hune zvinhu zvakafanana semulsion. Mushure mokunge mvura inoputika, inogona kuumba firimu. Iyo firimu ine yakakwira kuchinjika, yakakwira mamiriro ekunze, uye inoratidza yakakwira kunamatira kune akasiyana substrates.
Naizvozvo, chinhu chinodiwa mbishi mudhaka yakaoma-yakasanganiswa, iyo inogona kuvandudza mashandiro, kuwedzera simba, kunatsiridza kunamatira kwehupfu hwakaoma kune akasiyana substrates, kunatsiridza kuchinjika, kumanikidza simba, uye kupfeka kuramba kwehupfu hwakaoma dhaka. Mukuwedzera, Kana yakasanganiswa nehydrophobic latex powder, inogona kuita kuti iyo yakaoma poda dhaka isapinda mvura.
2. Cellulose
Cellulose ine viscosities yakasiyana ine kushandiswa kwakasiyana. Cellulose inogona kushandiswa mune yakaderera-giredhi putty poda yemukati madziro, iyo inogona kuomesa kuchengetwa kwemvura uye kuwedzera chiyero. Yakagadzikana mumakemikari, inogona kudzivirira mildew, ine yakanaka yekuchengetedza mvura, uye haina kukanganiswa nekuchinja kwepH kukosha. Inogona kushandiswa kubva ku50,000 kusvika ku200,000 viscosities. Kusimba kwechisungo kunopesana, viscosity yakakwira, asi simba racho idiki, kazhinji pakati pe50,000 ne100,000. Zvinonyanya kuwedzera kuenzana uye kuvakwa kwevhu rakaoma dhaka, uye zvakakodzera kuderedza huwandu hwesimende.
Mukuwedzera, dhaka resimende rine nguva yekusimbisa. Munguva yekusimbisa nguva, kugadziriswa kwemaoko kunodiwa kuti uchengetedze hunyoro. Pamusana pekuchengetedzwa kwemvura ye cellulose, hunyoro hunodiwa pakusimbiswa kwevhu hunogona kuwanikwa kubva pakuchengetedza mvura ye cellulose, saka inogona kusimbiswa pasina kunyatsogadzirisa.
3. Lignin
Basa re lignin muvhu rakaoma dhaka nderokudzivirira kuputika. Kana lignin yakaparadzirwa mumvura, iripo muchimiro chepfupi fibers. Semuenzaniso, pakuvaka madziro nevhu munzvimbo dzemumba, mashanga egorosi nemashanga emupunga zvinowedzerwa kudzivirira kutsemuka. Paunenge uchishandisa lignin, zviri nani kusarudza zvinhu zvakachena pasina tsvina. Paunenge uchizivisa lignin, unogona kushandura lignin kuti uone kana paine guruva rasara. Iyo yakawanda yehupfu, iyo yakaipisisa kunaka. Kana kuisa zvishoma lignin mumvura uye cherechedza, zviri nani kupararira, zviri nani kunaka, izvo zvinoreva kuti kana yakawedzerwa kune yakaoma poda dhaka, zviri nyore kupararira uye hazvizogadziri bhora.
4. Inorganic bonding zvinhu
Ash calcium powder is calcium hydroxide, inowanzoshandiswa inorganic bonding material. Iyo inonyanya kuita basa rekubatanidza mu putty poda kuti iwane isina mvura uye inodzivirira mvura mhedzisiro. Kune nzvimbo dzakawanda dzinogadzira limestone muChina, saka kugadzirwa kwe lime calcium powder kwakajairika. Nekudaro, mune dzimwe nzvimbo, iyo putty mortar yakagadzirwa ne lime calcium poda inogadzirwa inogona kupisa ganda remaoko panguva yekuvaka. Exothermic reaction, saka kunyorwa kweash calcium poda yakanyanya alkaline. Iyo yakakura iyo dhizaini, ndiyo inonyanya kugadzikana, uye iri nyore kutsemuka kana ichikweshwa pamadziro. Tiri kutsvaga zvinhu zvine hupfu hwakadzikama hupfu hwekarusiyamu, hune diki diki, kuchena kwakanaka, uye haabvise maoko.
