Hydroxypropyl starch is a modified starch ine maapplication mumaindasitiri akasiyana siyana, kusanganisira indasitiri yekuvaka kuti ishandiswe mukugadzira dhaka.Dope musanganiswa wesamende, jecha nemvura inoshandiswa kusunga zvidhinha kana matombo.Kuwedzera hydroxypropyl starch kudhaka inoshanda zvakasiyana siyana uye inosimudzira mashandiro ayo mumashandisirwo ekuvaka.
Heano mamwe akakosha maficha ehydroxypropyl starch yedhaka:
Kuchengetedzwa kwemvura: Hydroxypropyl starch inoshanda sechinhu chekuchengetedza mvura mudhaka.Inobatsira kuderedza kubuda kwemvura panguva yekurapa, kuve nechokwadi chekuti dhaka rinochengeta hunyoro hwakakwana.Izvi zvakakosha pakuita hydration yakakodzera ye simenti, nekudaro kuwedzera simba uye kusimba kwedhaka.
Kuvandudzwa kwekushanda: Kuwedzerwa kwehydroxypropyl starch kunosimudzira kushanda kwedhaka.Inovandudza kuwirirana uye nyore kushandisa, zvichiita kuti zvive nani kunamatira kune zvivakwa zvekuvaka.Izvi zvinonyanya kukosha pamapurojekiti ekuvaka uko kuve nyore kubata uye kushandiswa kwedhaka kwakakosha.
Kuisa nguva yekudzora: Hydroxypropyl starch ichakanganisa nguva yekumisikidza yedhaka.Nekugadzirisa huwandu hwehydroxypropyl starch inoshandiswa, makondirakiti anogona kudzora nguva yekumisikidza yemusanganiswa wedhaka.Izvi zvinobatsira mune dzakasiyana siyana dzekuvaka panodiwa nguva dzekumisikidza dzakakwana kuti zviite zvakakwana.
Deredza Shrinkage: Shrinkage idambudziko rinowanzoitika nedhaka uye rinogona kukonzera kuputika mukugadzirwa kwakapedzwa.Hydroxypropyl starch inobatsira kuderedza shrinkage nekuderedza kurasikirwa nehunyoro panguva yekurapa.Izvi zvinobatsira kuvandudza kusimba kwese kwedhaka uye chimiro chayo chekutsigira.
Enhanced adhesion: Iko kunamatira kwedhaka kwakakosha pakugadzikana uye hupenyu hurefu hwezvivakwa zvekuvaka.Hydroxypropyl starch inogona kuwedzera kunamira kwedhaka kune akasiyana substrates uye kupa chisungo chakasimba pakati pedhaka uye zvekuvaka.
Resistance to Sag: Mumashandisirwo akatwasuka, akadai sekupurasita kana kupurasita madziro, kuramba kwedhaka kuti isag kwakakosha.Hydroxypropyl starch inobatsira kune thixotropic zvimiro zvedhaka, kuderedza mukana wekudonha uye nekuona yunifomu ukobvu mune vertical application.
Kuenderana nezvimwe zvinowedzera: Hydroxypropyl starch inowanzoenderana nezvimwe zvinowedzera zvinoshandiswa mukugadzira dhaka.Uku kuita kwakasiyana-siyana kunobvumira makondirakiti kuti agadzirise musanganiswa wedhaka kune chaiwo mapurojekiti anodiwa, achitora mukana wekubatana pakati pezvimwe zvinowedzera.
Mafungiro ezvakatipoteredza: Starch-based additives, senge hydroxypropyl starch, inowanzoonekwa seine hushamwari.Iwo ane biodegradable uye ane kushoma kwezvakatipoteredza zvichienzaniswa nezvimwe zvekugadzira zvekuwedzera.
Hydroxypropyl starch inoita basa rakakosha mukuvandudza mashandiro ematokari ekuvaka.Mabhenefiti anosanganisira kunatsiridza kuchengetedza kwemvura, kugadzirisika, kuseta nguva yekudzora, kuderedzwa shrinkage, kuwedzeredzwa kunamatira, sag kuramba, kuenderana nezvimwe zvinowedzera, uye kufunga kwezvakatipoteredza.Izvi zvivakwa zvinoita kuti hydroxypropyl starch ive yekuwedzera yakakosha pakugadzirwa kwemhando yepamusoro uye yakasimba zvekuvaka.
