Cellulosesvari kuwedzera kushandiswa mumasimendi-akavakirwa zvinhu, kunyanya mune yakaoma motsi, nekuda kwekuchengetwa kwemvura yavo kwazvo uye nemhedzisiro yakakora. Naizvozvo, zvivakwa uye maitiro ekugadziracellulose ether yakagadziridzwa cement-yakavakirwa zvinhu uye kudyidzana pakaticellulose ether Uye simende slurry zvishoma nezvishoma ichave inotarisisa yekutarisisa muminda yezvivakwa zvekuvaka uye mainjiniya mumakore apfuura. Mazhinji mikana yekutsvaga yakawanikwa. Kubatanidza Kutsvaga Kufambira mberi kumba uye kunze kwenyika, pachine matambudziko anotevera mukutsvagisa uye kushandiswa kwecellulose ether Yakagadziridzwa Cement-Yakavakirwa Zvigadzirwa:
1.The marudzi mazhinji ecelluloses.Kunyangecelluloses Inoshandiswa mumidziyo yemasimendi yakakamurwa mumhando dzakawanda senge hemc, hemc uye hpmc nekuda kweiyo degree ravo rekutsiva. Mhando imwechete yecellulosesIva nemisiyano yakawanda mune molecular chimiro, mamekari uremu, degree rekutsiva kana kutsiva zvirimo. Parizvino, research Inonyanya kutsvagisa kumba uye kune dzimwe nyika inotarisa pane imwe kana akati wandeicelluloses.Sarudzo yecellulose ether inogumira kuminda yavo yekunyorera yekushandisa. Iyo molecular chimiro hunhu hwecelluloses Hazviratidzwe, uye kumiririra kwavo hakusi kumiriri. Mhedziso ndiyo mhedzisiro isingadzivisiki ye "kusarudzika kutsiva", uye pane kupesana uye kukakavara pakati pemhedzisiro yemiedzo. Naizvozvo, zvakafanira kuti udzidzise zvakarongeka kuongororwa uye zvivakwa zvemhando uye michina yemarudzi akasiyana ecellulose ether yakagadziridzwa maegelling zvinhu.
2.Existing mabhuku akadzidza zvakakanganiswacelluloses pane zvakasiyana-siyana zvekushandisa zvemasimisiki, uye vakaita imwe ongororo yeiyo fomu yekuumbwa, asi yakundikana kuona hukama pakati peiyo molecular chimiro checelluloses uye zvivakwa zvemasimende akasarudzika slurry. Kugara uchigara, uye pane misiyano iri pachena mumuchina wavo. Pakaticellulose ether-Zvirongwa zvemhando yepamusoro, pane zvigadziko zvishoma pane zvigadzirwa zvine mwero akasiyana-siyana, izvo hazvigone kutsanangura maitiro ekufananidzira ezvivakwa zvakasiyana siyana zvecellulose ether-Mukati memukati mement-based zvigadzirwa. . Kunyangwe mamwe mabhuku akawana izvozvocelluloses Nemidziyo yakasiyana-molecular ine mhedzisiro dzakasiyana pane hydration yeiyo simende, izvo zvikonzero zvechikonzero hazvisati zvave zvichiramba zvakanaka.
3.Muchina wekumanikidza kwecellulose ether PaSepy Hydration Kinemics inosara yekudzoserwa. Parizvino, maererano neye akanonoka hydration mechanism yecellulose ether, Kunyangwe adsorption inoonekwa seicho chikonzero chaicho chekunonoka hydration yecellulose ether, zvinowanikwa kuti iyo yakasimba iyo yekushambadzira yekusagadzikana pakati pehydration zvigadzirwa uyecellulose ether, iyo yakanonoka kuderera kwesimende. Iyo adsorption mechani pakaticelluloses uye simende hydration zvigadzirwa, pamwe nezvikonzero zveiyo yakasarudzika adsorption capitiities yeakasiyanacelluloses uye simende hydration zvigadzirwa, haina kuwedzeredzwa.
4.Existing mabhuku anoratidza izvozvocelluloses inogona kukanganisa zvakanyanya chimiro chePore yeiyo coment-yakavakirwa zvinhu.Celluloses vanotendwawo kuve pamusoro-vanoshanda uye vane mhepo-yekushambadzira mhedzisiro pane nyowani simenti slurries, nekudaro inowedzera porosity yemasumbu akaomeswa slumment. Nekudaro, pesvedzero yecelluloses Pakugara uchigara uye kuumbwa kwemuchina wesimbe slurry pore saizi yekugovera haiwanzo kukurukurwa.
5. Rheological Properties chikamu chakakosha chekushandiswa kwecelluloses mumasimendi-akavakirwa zvinhu. Nehurombo, kune vashoma vatsva pazvinhu zvakatsanangurwa zvecellulose ether yakagadziridzwa simenti slurry kumba uye kunze kwenyika.
