Kuchengetwa kwemvura chiyero cheHPMC hydroxypropyl methylcellulose kushandiswa zvakare, kuchengetedza kwemvura kuita kwezvakanaka nezvakaipa zvakare kunokanganiswa nevazhinji vanogadzira mudzimba dhaka rakaoma, kunyanya tembiricha yepamusoro yekucherekedza kwefekitori yekumaodzanyemba, panguva imwe chete, pakanga paine zvikonzero zvakawanda zvinokanganisa mhedzisiro. yemvura yakaoma yepoda yevhu, senge kuwedzera vhoriyamu, viscosity, particle fineness pamwe nekushandiswa kwezvakatipoteredza, tembiricha, nezvimwe.
Mune yakaoma-yakasanganiswa pre-yakasanganiswa dhaka process, iyo yekuwedzera huwandu hwehydroxypropyl methyl cellulose yakaderera.Kunyangwe huwandu hwekuwedzera huri hwakaderera, hunogona kuvandudza mashandiro edhaka rakanyorova, iro ririwo chinhu chikuru chekuwedzera chinokanganisa kuita kwekuvaka kwedhaka.Naizvozvo, iyo sainzi uye inonzwisisika kusarudzwa kwe cellulose ether ine mhando dzakasiyana, viscosity yakasiyana, akasiyana particle fineness uye kuwedzera huwandu kune pesvedzero huru pakuvandudzwa kweiyo yakaoma-yakasanganiswa yakagadzirira-yakasanganiswa dhaka kuita.
Nekuda kwenzvimbo yekuvaka yemazuva ano, ikozvino masonry akawanda uye kupurasita kwemvura kuita kwemvura hakuna kunaka, nzvimbo yakanyarara kwemaminetsi mashomanana ingave yekuparadzanisa kwemvura, uye kuchengetedza mvura ndeye hydroxypropyl methylcellulose ether basa guru, mvura-soluble cellulose ether mu dhaka rakagadzirwa-yakasanganiswa rine basa rakakosha, basa repamusoro pepamusoro rine matatu, rimwe, Zvinechekuita zvakanaka kuchengetedza mvura kuita, chechipiri, pesvedzero pakusimba uye thixotropy yedhaka rakagadzirwa-yakasanganiswa, chechitatu, pesvedzero yekudyidzana nesamende. .Hydroxypropyl methylcellulose kuchengetedza kwemvura kuita kunonyanya kuenderana nehwaro hwekunyudzwa kwemvura, kuumbwa kwedhaka, dhaka rakakora makubvu, uye dhaka remvura zvinodiwa, uye nguva yekutsikirira kwechinhu che condensation, ye cellulose ether kuzvidzora kwemvura, kunyanya kubva pakunyungudika kwechisikigo uye kupera simba. ye celluloseether.
Hydroxypropyl methylcellulose inobata basa rinokosha mukugadzirisa kwevhu rakaoma-rakasanganiswa rakagadzirwa-yakasanganiswa dhaka, iro rinogona kuita basa mukuchengetedza mvura, kuwedzera, kunonoka simba re hydration ye simenti, uye inogona kuvandudza kushanda kwekuvaka.Kuita kwakanaka kwekuchengetedza mvura kunogona kuita kuti simende hydration iwedzere kuwanda, inogona kuvandudza yakanyorova viscosity yedhaka rakanyorova, kuitira kuti ivandudze kusimba kwechisungo chedhaka, asi zvakare inogona kugadzirisa nguva.Kuwedzera hydroxypropyl methylcellulose ether mukugadzira yakaoma yakasanganiswa yakasanganiswa yakasanganiswa dhaka inogona kuvandudza kushanda kwekuvaka kwedhaka, inogona kuvandudza simba rekugadzirisa, kuitira kuti rishandiswe zvakanyanya mumunda wedhaka rekushandisa.
