Kuvandudza Dry Mortar neHPS Admixture

Starch ethers, senge hydroxypropyl starch ether(HPS), inogona zvakare kushandiswa semisanganiswa kusimudzira maumbirwo edhaka rakaoma. Heino nzira iyo starch ether admixtures inogona kuvandudza dhaka rakaoma:

1. Kuchengetedzwa Kwemvura: Starch ether admixtures inovandudza kuchengetedza kwemvura mumatope akaoma maumbirwo, akafanana neHPMC. Ichi chivakwa chinobatsira kudzivirira kuoma kusati kwasvika kwemusanganiswa wedhaka, kuve nechokwadi chekuwedzera nguva yekushanda uye nekuvandudza kushanda.
2. Kushanda uye Kupararira: Starch ethers inoshanda se rheology modifiers, inosimudzira kushanda uye kupararira kweakaoma dhaka musanganiswa. Ivo vanobatsira dhaka kuti riyerere zvakanaka panguva yekushandisa uku ichichengetedza kugadzikana uye kudzivirira kudonha kana kudonha.
3. Adhesion: Starch ether admixtures inogona kuwedzera kunamira kwedhaka rakaoma kune akasiyana substrates, kukurudzira zvirinani kunyorova uye kubatana pakati pedhaka ne substrate. Izvi zvinoguma nekunamira kwakasimba uye kwakasimba, kunyanya mumamiriro ekunetsa ekushandisa.
4. Yakaderedzwa Shrinkage: Nekuvandudza kuchengetwa kwemvura uye kuenderana kwese, starch ethers inobatsira kuderedza shrinkage panguva yekurapa kwedhaka rakaoma. Izvi zvinotungamira kuderedzwa kutsemuka uye kuvandudzwa kwesimba rezvisungo, zvichikonzera mamwe akavimbika uye anogara kwenguva refu edhaka majoini.
5. Flexural Strength: Starch ethers inogona kubatsira kune kuchinjika kwesimba rekuoma kwedhaka maumbirwo, zvichiita kuti risarambe kuputika uye kukuvara kwechimiro. Ichi chivakwa chinobatsira mukushandisa uko dhaka rinoiswa pasi pekukotama kana kuchinjika masimba.
6. Kupokana Nezvezvakatipoteredza Zvinhu: Dry dhaka maumbirwo akagadziridzwa ane starch ethers anogona kuratidza kukwidziridzwa kupikisa kune zvakatipoteredza zvinhu zvakaita sekuchinja kwetembiricha, hunyoro, uye kutonhora-kunyorova kutenderera. Izvi zvinovimbisa kushanda kwenguva refu uye kugadzikana mumamiriro ekunze akasiyana-siyana.
7. Durability: Starch ether admixtures inogona kuwedzera kusimba kwese kwedhaka rakaoma nekuvandudza kuramba kupfeka, abrasion, uye kuratidzwa kwemakemikari. Izvi zvinoguma nekugara kwenguva refu majoini edhaka uye kuderedzwa kwekugadzirisa zvinodiwa nekufamba kwenguva.
8. Kuenderana Nezvimwe Zvinowedzerwa: Starch ethers inopindirana neyakasiyana-siyana yezvimwe zvinowedzera zvinowanzo shandiswa mukugadzirwa kwedhaka rakaoma, zvichibvumira kushanduka mukugadzira uye kugonesa kugadziridzwa kwemusanganiswa wedhaka kuti usangane nezvinodiwa zvekushanda.

Zvakakosha kuziva kuti nepo starch ethers ichipa mabhenefiti akafanana kune HPMC maererano nekuchengetedza mvura nekusimudzira kushanda, maitiro avo ekuita uye mwero wakakwana wedosi inogona kusiyana. Vagadziri vanofanira kuita ongororo yakakwana uye optimization kuti vaone iyo yakanyanya kufanira starch ether musanganiswa uye magadzirirwo ezvavanoda zvekushandisa. Pamusoro pezvo, kushandira pamwe nevatengesi vane ruzivo kana vagadziri vanogona kupa ruzivo rwakakosha uye nerutsigiro rwehunyanzvi mukugadzirisa maumbirwo edhaka rakaoma rine starch ether admixtures.
