Kushandiswa kweHPMC mune yakaoma poda dhaka

HPMC (Hydroxypropyl Methyl Cellulose) inowanzoshandiswa mukugadzirwa kwedhaka rakaoma nekuda kwehuwandu hwayo hunobatsira. Izvi zvinotevera mamwe mashandisirwo eHPMC mune yakaoma poda dhaka:

Kuchengetedzwa kwemvura: HPMC inoshanda sechinhu chekuchengetedza mvura mune yakaoma dhaka maumbirwo. Inotora uye inochengetedza unyoro, kudzivirira kukurumidza kubuda panguva yekurapa. Ichi chivakwa chinobatsira kuvandudza kushanda, kuwedzera nguva yakavhurika uye inosimudzira kuita kwese kwedhaka.

Kushanda uye kupararira: HPMC inoshanda se rheology modifier kuti iwedzere kushanda uye kupararira kwevhu rakaoma dhaka. Iine mafuta ekuzora, zvichiita kuti zvive nyore kusanganisa, kuisa uye kuparadzira dhaka. Izvi zvinovandudza kusimba kwechisungo uye kunamatira kwedhaka kune akasiyana substrates.

Anti-Sag uye Anti-Slip: HPMC inobatsira kuderedza sag uye kutsvedza kwedhaka rakaoma panguva yekuvaka yakamira kana pamusoro. Iyo inowedzera viscosity uye kubatana kwedhaka uye inodzivirira dhaka kubva pakutsvedza kana kudonha isati yagadzika. Izvi zvinonyanya kukosha kumisikirwo yakatwasuka, senge tile yekunamira kana plastering application.

Yakavandudzwa Bond Simba: HPMC inokwidziridza kunamatira uye chisungo simba rematope akaoma kune akasiyana siyana, kusanganisira kongiri, masonry uye mataira. Iyo inoumba firimu rakatetepa pamusoro peiyo substrate, inosimudzira kunamatira zviri nani uye kuderedza njodzi yekupenengura kana delamination.

Crack kuramba uye kusimba: HPMC inovandudza kusimba kwese uye kutsemuka kuramba kweakaoma musanganiswa dhaka. Inobatsira kuderedza shrinkage uye kuderedza kugadzirwa kwekuputika panguva yekuomesa nekurapa. Izvi zvinowedzera kushanda kwenguva refu uye kutendeseka kwechimiro chedhaka.

Kuenderana nezvimwe zvinowedzera: HPMC inowirirana nezvimwe zvakasiyana-siyana zvekuwedzera zvinoshandiswa muvhu rakaoma dhaka maumbirwo, akadai seplasticizers, air-entraining agents uye dispersants. Inogona kusanganiswa nyore nyore neaya ekuwedzera kuti uwane inodiwa maitiro ekuita uye optimize maumbirwo.

Izvo zvakakosha kuti ticherechedze kuti iyo chaiyo huwandu hweHPMC hunoshandiswa mukuoma musanganiswa dhaka kugadzirwa kunogona kusiyana zvichienderana nezvinhu zvakaita sekuda kuenderana, nzira yekushandisa uye mamiriro ezvakatipoteredza. Vagadziri uye vatengesi vanowanzopa nhungamiro uye kurudziro maererano nekushandiswa kwakakodzera uye dosi yeHPMC mumashandisi akaoma edhaka.
