Mhedzisiro yeRabha poda uye cellulose muTile Adhesive

Tile inonamira ndechimwe chezvinhu zvakakura zvekushandisa zvakakura zveakakosha zvakaoma-zvakasanganiswa muridzi parizvino. Urwu rudzi rwechirume sechinhu chikuru chemasangano uye chinowedzerwa neakakwiridzwa Aggregates, vamiriri vemvura, vekutanga vamiririri vepwere, Latex hupfu uye magetsi kana elgoranic. musanganiswa. Kazhinji, zvinongoda kusanganiswa nemvura kana ichishandiswa. Kuenzaniswa neyakajairwa sumbemed, kunogona kunatsiridza zvakanyanya simba rekubatanidza pakati pekusatarisana nezvinhu uye substrate, ine tsika dzakanaka dzekupikisa uye ine simba rakanakisa uye kupokana nekushisa. Uye zvakanakira kusununguka-thaw kutenderera kwekuramba, kunyanya kushandiswa kune madziro emadziro uye kubva kune madziro emukati, maChinzvimbo yekushongedza

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 ethi mune tile inonamatira kwete chete izvo zvimisheni zvePorcelain zvinonamatira, sekushanda kwakanyanya, banga kunamatira, etc. Pesvedzero panguva yekuvhura yeTile inonamatira

Kana rubber poda uye cellulose ether co-turner moturu, imwe data inoratidzira kuti yakasimba yerinetic zvigadzirwa, uye cellulose ether inowanikwa mune iyo intertitial fluid, iyo inobata mongororo yekuvhara uye yekugara nguva. 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, iyo firimu kugadzirwa kwe cellulose ether pamusoro pehudyu ine pesvedzero huru pakuita kwemutumbi.

1) Iyo firimu rakaumbwa rakatetepa uye richanyungudutswa kaviri, kutadza kudzikisira kubuda kwemvura 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

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. Mukuwedzera, cellulose ether inoderedza kusimuka kweIN ((ca2 +, so42-, ...) Mugumo wePore nekuda kwekuwedzera kweiyo pore solution, nekudaro kunonoka maitiro ehystem.

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.

"Kushandiswa kweCellulose Eteter muComent-based Dement zvigadzirwa" zvakataurwa kuti kudzoserwa kweCellulose ether zvinoenderana nechimiro chayo chemakemikari. Uye maitiro akajairwa akagumisa ndezvekuti MHEC, iyo yakakwira mwero we methylation, zvidiki zvekudzosera mari ye 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.

Miedzo yeSystem yakaona zvakare kuti zvirimo zvevakatsauka zvinoita basa rakakosha musimba rekushatira. For hpmc, imwe dhigirii yekupa inodikanwa kuti ive nechokwadi chekunyura kwayo kwemvura uye kuiswa kwechiedza. Zviri mukati mezvinyorwa zvakare zvinosarudza simba reHPMC. Iyo tembiricha yeGel inotema zvakare inoshandisa nzvimbo yekushandisa yeHPMC. Within a certain range, an increase in the content of methoxyl groups will bring about a downward trend in the pull-out strength, while an increase in the content of hydroxypropoxyl groups will lead to a decrease in the pull-out strength. kusimuka maitiro. 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.
