Kuvandudza Mortar Yakaoma neHPS Admixture

Mastarch ether, akadai sehydroxypropyl starch ether (HPS), anogonawo kushandiswa seadmixtures kuti awedzere dry mortar formulations. Heino mashandisirwo anoitwa starch ether admixtures kuti awedzere dry mortar:

1. Kuchengetwa kweMvura: Kusanganiswa kwestarch ether kunovandudza kuchengetwa kwemvura mumafuta akaoma, zvakafanana neHPMC. Izvi zvinobatsira kudzivirira kuoma kwemusanganiswa wematope nguva isati yakwana, zvichiita kuti nguva yekushanda iwedzere uye kushanda zvakanaka.
2. Kushanda Uye Kupararira: Mastarch ethers anoshanda senzira dzekugadzirisa rheology, zvichiwedzera kushanda uye kupararira kwemusanganiswa wedhaka rakaoma. Anobatsira dhaka kuyerera zvakanaka panguva yekushandiswa uku achichengetedza kugadzikana uye kudzivirira kudzika kana kudonha.
3. Kunamira: Kusanganiswa kwestarch ether kunogona kuwedzera kunamira kwedhaka rakaoma kune zvakasiyana-siyana, zvichikurudzira kunamira zviri nani uye kubatana pakati pedhaka nedhaka. Izvi zvinoita kuti kunamira kwakasimba uye kugare kwenguva refu, kunyanya mumamiriro ezvinhu akaoma ekushandisa.
4. Kuderedzwa kweStricle: Nekuvandudza kuchengetwa kwemvura uye kugara zvakanaka, starch ethers inobatsira kuderedza stricle panguva yekupisa dhaka rakaoma. Izvi zvinoderedza kutsemuka uye simba rekubatanidza, zvichikonzera kuti dhaka rigare kwenguva refu uye rakavimbika.
5. Simba reKuchinjika: Mastarch ether anogona kubatsira pakusimba kwesimba remad mortar formulations, zvichiita kuti arambe achidzivirirwa pakutsemuka nekukuvadzwa kwechimiro. Izvi zvinobatsira mukushandiswa kwemortar kana kuti madmostari.
6. Kuramba Zvinhu Zvakatipoteredza: Mafomu edhaka rakaoma akawedzerwa starch ethers anogona kuratidza kusimba kuri nani kwezvinhu zvakatipoteredza zvakaita sekuchinja kwetembiricha, hunyoro, uye kunyunguduka kwechando. Izvi zvinoita kuti ishande kwenguva refu uye igare zvakanaka mumamiriro akasiyana-siyana ekunze.
7. Kugara kwenguva refu: Kusanganiswa kwestarch ether kunogona kuwedzera kugara kwenguva refu kwedhaka rakaoma nekuvandudza kuramba kusingakuvadzi, kukweshwa, uye kushandiswa nemakemikari. Izvi zvinoguma nekureba kwenguva refu kwemajoini edhaka uye kudzikira kwezvinodiwa zvekuchengetedza nekufamba kwenguva.
8. Kuenderana Nezvimwe Zvinowedzerwa: Starch ethers inoenderana nezvimwe zvinowedzerwa zvakasiyana-siyana zvinowanzoshandiswa mukugadzira dry mortar formulations, zvichibvumira kushanduka mukugadzira uye zvichiita kuti zvigadziriswe zvemusanganiswa wemortar kuti zvienderane nezvinodiwa zvekushanda.

Zvakakosha kuziva kuti kunyange hazvo starch ethers dzichipa mabhenefiti akafanana neHPMC maererano nekuchengetedza mvura uye kuwedzera kushanda kwayo, hunhu hwadzo hwekushanda uye mwero wemuyero wakakodzera zvinogona kusiyana. Vagadziri vanofanirwa kuita bvunzo dzakakwana uye kugadzirisa kuti vaone musanganiswa wakakodzera westarch ether uye fomura zvinoenderana nezvinodiwa zvavo. Pamusoro pezvo, kushanda pamwe chete nevatengesi vane ruzivo kana vagadziri vemaformula kunogona kupa ruzivo rwakakosha uye rutsigiro rwehunyanzvi mukugadzirisa dry mortar formulations ne starch ether admixtures.
