Pane zvakawanda zvinokanganisa kushandiswa kwehydroxypropyl methylcellulose HPMC mune zvekuvaka, kunyanya gypsum-based plaster, sezvinotevera:
1 kuchengetedza mvura
Hydroxypropyl methylcellulose yekuvaka inodzivirira kunyura kwakanyanyisa kwemvura neiyo substrate, uye kana gypsum yanyatsogadzika, mvura inofanira kuchengetwa mupurasita zvakanyanya sezvinobvira.Hunhu uhwu hunodaidzwa kuti kuchengetwa kwemvura uye hunoenderana zvakananga kune viscosity yekuvaka-chaiyo hydroxypropyl methylcellulose mhinduro mune stucco.Iyo yakakwirira iyo viscosity yemushonga, iyo inowedzera simba rayo rekuchengetedza mvura.Kana huwandu hwemvura huchiwedzerwa, simba rekuchengetedza mvura rinoderera.Izvi zvinodaro nekuti iyo yakawedzera mvura inoderedza mhinduro yehydroxypropyl methylcellulose yekuvaka, zvichikonzera kudzikira kweviscosity.
2 anti-sagging
Plaster ine anti-sag zvivakwa inobvumira vanonyorera kuti vaise majasi akakora pasina kudonha, uye zvakare zvinoreva kuti iyo plaster pachayo haisi thixotropic, iyo yaizotsvedza pasi panguva yekushandisa.
3 Deredza viscosity, kuvaka nyore
Yakaderera-viscosity uye nyore-kugadzira gypsum plaster inogona kuwanikwa nekuwedzera akasiyana-siyana ekuvaka-chaiyo hydroxypropyl methylcellulose zvigadzirwa.Paunenge uchishandisa yakaderera-viscosity mamakisi ekuvaka-chaiyo hydroxypropyl methylcellulose, dhigirii ye viscosity yakaderera kuderera Kuvaka kunova nyore, asi kuchengetedza kwemvura kweiyo low-viscosity hydroxypropyl methylcellulose yekuvaka haina kusimba, uye iyo yekuwedzera mari inoda kuwedzerwa.
4 Kuenderana kwe stucco
Nokuda kwehuwandu hwakatarwa hwedhaka rakaoma, zvinowedzera hupfumi kuti hubudise huwandu hwepamusoro hwehutu hunonyorova, hunogona kuwanikwa nekuwedzera mamwe mvura uye mabhubhu emhepo.Asi huwandu hwemvura uye mhepo inoputika yakawandisa
