SEMEN-Yakavakirwa Tile Ageshising parizvino yakanyanya kushandiswa kwekunyorwa kweiyo nzvimbo yakaoma, iyo inowedzerwa kune vamiriri veganhura, vamiriri vekutanga Kazhinji, zvinongoda kusanganiswa nemvura kana ichishandiswa. Kuenzaniswa neyakajairwa sumbement dolita, inogona kuvandudza kwazvo simba rekubatanidza pakati pekutarisana nezvinhu uye substrate, uye ine yakanaka yekupesana uye kupesana kwakanaka uye kupokana kwemvura uye kupokana kwemvura. Izvo zvinonyanya kushandiswa kuderedza zvekushongedza zvekugadzira sekuvaka kwemukati uye pasi marara, etc. Zvinoshandiswa zvakanyanya mumaruva uye ekunze, pasi, zvipuka, makicheni uye dzimwe nzvimbo dzekushambadzira. Parizvino parizvino inoshandiswa zvakanyanya tile yekubatanidza zvinhu.
Kazhinji kana tichitonga mashandiro e tiles inonamatira, isu hatitarisire kunamatira kwaro uye kugona kweAnti-kutsvedza, asi zvakare teerera kune yayo yekunyora simba uye nguva yekuvhura. Cellulose etle mumhepo inonamatira isingabatanidze zvivakwa zvePorcelain zvinonamatira, zvakadai sekushanda kwakanaka, etc.,
2. Iko kukanganisika pane iyo nguva yekutanga yeTile inonamatira
Kana rubber poda uye cellulose ether co-mufuro wemvura, mamwe maitiro ehupfumi anoratidza kuti kusimba kweHydration Zvigadzirwa Pasi pepasi reCellulose ether yakakwira kupfuura iyo yeRubber poda pane iyo dhizaini ichabatsira kuumbwa kweHydrogen zvisungo pakati peiyo base pasi uye cellulose ether.
Mumvura ine mvura, mvura iri mudura, uye cellulose ether inofumiswa pamusoro pemaminetsi ekuti inofamba-famba ichaunza zvimwe cellulose ether enrichment pane dhiri.
Naizvozvo, kuumbwa kwemafirimu kwe cellulose ether pamusoro peguruva kune pesvedzero huru pakuita kweiyo dorari. 1) Iyo firimu rakaumbwa rakatetepa uye richanyungudutswa kaviri, risingagoni kudzikisira mvura yemvura uye kuderedza simba. 2) Iyo firimu rakaumbwa rakanyanya kukwikwidza, kusunganidzwa kwemasero eCellulose mumvura inonakidza, uye zvikwangwani zvakakwira, saka hazvisi nyore kuputsa iyo firimu kana matairi ari mawadhi. Zvinogona kuoneka kuti iyo firimu-yekuumba midziyo ye cellulose ether ine zvakakanganisa nguva yakazaruka. Type yeCellulose ether (Hpmc, hemc, hemc, etc.) uye degree rekutsiva
3. Simba rekutora simba
Kuwedzera pakupa izvo zviri pamusoro-zvinotaurwa zvataurwa zvinobatsira kune messar, cellulose ther zvakare zvinonyangarika iyo hydration kinetics ye siment. Iyi yekudzora mhedzisiro inonyanya kukonzerwa neyemusangano weCellulose ether mamorekusa pane dzakasiyana-siyana menerralles inonyanya kushambidzwa pamvura yakadai seCSH uye calcium hydroxide. Pane zvigadzirwa zvemakemikari, hazviwanzo kushambadzirwa pane yekutanga mineral chikamu che clinker. Uye zvakare, cellulose ether inoderedza kusimuka kweINS (CA2 +, so42-, ...) Mukupindurudza kwesangano remugumo wePore, nekudaro kunonoka maitiro ekunyora.
Viscosity imwe yeparamende yakakosha, iyo inomiririra maitiro emakemikari e cellulose ether. Sezvataurwa pamusoro apa, viscosity inonyanya kubata mukana wekuchengetwa kwemvura uye zvakare zvine hunhu hwakakosha pakubata kweiyo nyowani nyowani. Nekudaro, zvidzidzo zvekuyedza zvakawana kuti viscosity yemasero e cellulose ether ine kanenge isina mhedzisiro paStember Hydration Kinetics. Mhelecular uremu hurefu husina kunaka pane hydration, uye musiyano wepamusoro pakati pehuremu hwakasiyana hwemanyorerwe anongova 10min chete. Naizvozvo, suremu hwemolecular haisi kiyi paramende yekudzora siment hydration.
Kudzoserwa kwe cellulose ether zvinoenderana nechimiro chayo chemakemikari, uye maitiro akajairwa akagumisa kuti, kweMEC, iyo yakakwira mwero wemafari e cellulose ether. Uye zvakare, kudzoreredzwa kwehydrophilic kutsiva (sekutsiva kune hec) kwakasimba kupfuura izvo zvehydrophobic kutsiva (akadai sokunge kutsiva mH, mhec, mhpic). Iko kudzoreredzwa kwemasero emasero ether kunonyanya kukanganiswa nemaratidziro maviri, iyo mhando uye huwandu hwemapoka akatsiva.
Kuedza kwedu kwakarongeka kwakawanawo kuti zvirimo zvevakatsauka zvinoita basa rakakosha musimboti wetsimba dzole. Takaongorora mashandiro eHPMC nemadhigirii akasiyana ekutsiva madhiza echiwi, uye akaedza nemhedzisiro ye cell vanomedza mapoka akasiyana pakurapa kwakasiyana pamigwagwa pazvinhu zve tiles.
Muedzo, isu tinofunga nezveHPMC, inova ether ether, saka isu tinofanirwa kuisa mifananidzo miviri pamwe chete. YeHPMC, inoda imwe nhanho yekunyora kuti ive nechokwadi chekunyura kwayo kwemvura uye kujekesa kwechiedza. Isu tinoziva zvirimo zvevakatsauka zvakare zvinosarudza tembiricha yeHPMC, iyo zvakare inosarudza nzvimbo yekushandisa yeHPMC. Nenzira iyi, boka reboka reHPMC iro rinowanzove rinoshandawo rakarongedzwawo mukati meiyo huwandu. Mune izvi huwandu, maitiro ekubatanidza nzira uye hydroxyprishitio kuti uwane iyo yakanyanya kunaka mhedzisiro ndeyekutsvaga kwedu. Figure 2 shows that within a certain range, an increase in the content of methoxyl groups will lead to a downward trend in the pull-out strength, while an increase in the content of hydroxypropoxyl groups will lead to an increase in the pull-out strength. Pane mhedzisiro yakafanana kune maawa ekuvhura.
Iyo shanduko yekuchinja kwesimba resimba pasi pemamiriro ezvinhu akavhurika mamiriro anoenderana neiyo pasi pemamiriro ekunze ekushisa. HPMC ine nzira yakakwira (DS) zvemukati uye yakaderera hydroxyprupoxyl (MS) zvirimo zvine hukasha hwakanaka hwefirimu, asi ichakanganisa dhizaini rakanyoroveswa pane kudaro. zvinhu zvinyoro-nyoro zvivakwa.
