Iyo yakadzika madhiri, iyo inoita basa rinokosha mukuvandudza mashandiro ezvivakwa kuomesa-kwakasanganiswa mota, maakaundi anopfuura makumi mana muzana emutengo wemutengo wakaoma-wakasanganiswa. Zvizhinji zveAdmiture mumusika wemba anopiwa nevatorwa nevatorwa, uye chirevo chezvigadzirwa zvinopihwa zvakare nevatengesi. Mutengo wechigadzirwa chakaoma-chakasanganiswa chakasimba kudaro, uye zvakaoma kugutsikana zvakajairika masonry uye kupururudza mucheka uye huwandu hwakawanda uye huwandu hwakawanda. Zvigadzirwa zvepamusoro-zvakadzika zvinodzorwa nemakambani ekunze, uye zvakaoma-zvakasanganiswa Vagadziri vane purofiti yakaderera uye mutengo usina kunaka wekutadza; Iko kushandiswa kweAdmintures kunoisa kurongeka kwakarongeka uye kwakarongedzwa kutsvagisa, uye zvinotevera zvisingaonekwe mafomula. Pano, zvatinogovana newe ndezvekuti, chii chinonzi basa re hydroxyprupropropyl methylcellose mune yakajairika admentures yeiyo yakaoma-yakasanganiswa dhaka?
HydroxyPropyl methylcellose ndeye cellulose akasiyana-siyana ndeayo yekubuda uye kushandiswa kwave kuri kuwedzera nekukurumidza mumakore achangopfuura. HydroxyPropyl methylcellose inogadzirwa nekotoni yakanatswa mushure mekurapa kweAlkalization uye methyl Iyo degree rekutsiva kazhinji 1.2 ~ 2.0. Zvivakwa zvayo zvakasiyana zvichienderana nezvinowanzoitika zvemukati zvemukati uye hydroxyprupyl zvemukati. Hunhu hwe hydroxyprupyl methylcellose zviri seinotevera:
1. Hydroxyprusyl methylcellose inonyudza mumvura inotonhora, uye ichasangana nematambudziko mukunyungudika mumvura inopisa. Asi tembiricha yayo yegungwa mumvura inopisa yakakwirira zvakanyanya kupfuura iyo ye methyl cellulose. Iyo solubility mumvura inotonhora inovandudzwa zvakare yakaenzaniswa ne methyl cellulose.
2. Iyo viscosity ye hydroxyprusyl methylcellose inoenderana neyakaomarara uremu. Iyo yakakura uremu hwemanyorerwe, yakakwira iyo viscosity. Tembiricha inokanganisawo zvavakaita, sekuwedzera kwekuwedzera, viscosity inoderera. Nekudaro, pesvedzero yeiyo yepamusoro viscosity uye tembiricha yakaderera pane iyo ye methyl cellulose. Kugadziriswa kwayo kwakasimba kana kuchengetwa pamhepo tembiricha.

4.. Caustic soda uye lime mvura ine zvishoma kushanda pane zvayo kuita, asi Alkali inogona kukurumidza kukurumidza kupaza uye zvishoma kuwedzera viscosity yayo. Hydroxyprupyl methylcellose yakachengetwa kune zvakajairika kumaronda, asi kana kusungwa kwemhinduro kwakakwirira, iyo visikopa yehydroxyproslose mhinduro inowanzowedzera kuwedzera.
5.. Senge polyvinyl doro, starch ether, miriwo gamu, nezvimwe.
6..
7. Kudonhedza kwe hydroxyprupyl methylcellose kune dhizaini yekuvaka yakakwira kupfuura iyo ye methylceulse.
