Hydroxypropyl starch for mortar is yakagadziridzwa starch inobuda iyo inowanzoshandiswa sechinhu chinowedzera mu simende-based mortar formulations. Rudzi urwu rwesitashi rwakagadziridzwa kemikari kuti ubatanidze mapoka ehydroxypropyl, ayo anokwidziridza mashandiro ayo nekushanda mumatope ekushandisa. Hydroxypropyl starch inobatsira kune dzakasiyana zvivakwa mudhaka, kuvandudza kushanda, kunamatira, uye kuchengetedza mvura.
Heano mamwe akakosha maitiro uye kushandiswa kwehydroxypropyl starch yedhaka:
Hunhu:
1. Kunyungudika kwemvura:
-Hydroxypropyl starch inowanzonyungudika mumvura, ichibvumira kuiswa nyore mumatope ekugadzira.
2. Yakagadziridzwa Chimiro:
- Kugadziriswa kwehydroxypropyl kunosanganisira kuunzwa kwemapoka ehydroxypropyl kune starch molecule, achichinja chimiro chayo.
3. Kukora Zvivakwa:
-Hydroxypropyl starch inoita seinokora mudhaka, ichipesvedzera viscosity yayo uye ichipa kugadzikana kwekuumbwa.
4. Yakanatsiridza Kunamatira:
-Kuwedzerwa kwe hydroxypropyl starch kunosimudzira adhesion zvivakwa zvedhaka, zvichitungamira mukuvandudzika kusungirirwa kune substrates.
5. Kuchengeta Mvura:
- Hydroxypropyl starch inobatsira mukuchengetedza mvura mukati medhaka, kudzivirira kuomesa zvakanyanya uye kuwedzera kushanda kwezvinhu.
Zvishandiso muMortar:
1. Kuwedzera Kwekushanda:
-Hydroxypropyl starch inovandudza kushanda kwedhaka nekufurira rheological properties. Izvi zvinonyanya kubatsira mumashandisirwo akadai sekupurasita uye kupa.
2. Kuvandudza Kunamatira:
- Mumataira anonamira uye mamwe maumbirwo edhaka, hydroxypropyl starch inosimudzira kunamatira, inosimudzira hukama huri nani pakati pedhaka uye substrate.
3. Kuchengeta Mvura:
- Iyo yekuchengeta mvura zvimiro zve hydroxypropyl starch yakakosha mumashandisi edhaka. Vanobatsira kudzivirira kuoma nekukurumidza kwedhaka, zvichibvumira nguva yekushanda yakawedzerwa uye kurapa kwakagadziridzwa.
4. Kuderedza Kudonha:
-Hydroxypropyl starch inobatsira kudzikisira kudonha mumashandisirwo akatwasuka, senge pakuisa dhaka kumadziro. Izvi zvinobatsira kuchengetedza ukobvu hunodiwa uye kufanana.
5. Kuwedzeredza Kuenderana:
- Iko kukora zvimiro zve hydroxypropyl starch inobatsira mukuenderana uye kuumbwa kwedhaka, zvichiita kuti zvive nyore kubata nekuisa.
Izvo zvakakosha kuti uzive kuti chaiyo kuita kwehydroxypropyl starch mudhaka application inogona kuenderana nezvinhu zvakaita sehuremu hwayo hwemamorekuru, dhigirii rekutsiva, uye kuumbwa kwese kwedhaka. Vagadziri vanowanzopa nhungamiro uye tekinoroji data sheets kubatsira mukushandiswa kwakakodzera kwehydroxypropyl starch mukugadzira dhaka.
