Basa rakakosha re cellulose ether mune motsi

Cellulose ether inogona kuvandudza zvakanyanya kuita kwekunyorova kwemvura, uye inonyanya kuwedzerwa inokanganisa kuita kwekuvaka kwemutumbi. Kusarudzwa zvine musoro kwe cellulose ana vana akasiyana siyana, zviyero zvakasiyana, madhigirii akasiyana emisangano uye akawedzera huwandu huchabatsira pakuvandudzwa kwekuita kweiyo yakaoma poda. Parizvino, zvakawanda masonry uye kupururudza motsi ane basa rekuchengetedza mvura, uye mvura slurry ichaparadzaniswa mushure memaminitsi mashoma ekumira. Kuchengetwa kwemvura kukosha kwekuita methyl cellelose ether, uye zvakare chiitiko icho vazhinji vemugadziri veimba vanogadzira mauto, kunyanya avo vari munzvimbo dzekumaodzanyemba vane tembiricha dzakakwirira, teerera. Zvinhu zvinokanganisa iyo yekuchengetwa kwemvura yeiyo yakaoma poda poda brar inosanganisira huwandu hwekuwedzera, viscosity, zviduku zvezvikamu, uye tembiricha yenzvimbo yekushandisa.

Kuchengeta kwemvura kwe cellulose ether

Mukugadzirwa kwezvinhu zvekuvakisa, kunyanya kuoma poda dowder, cellulose ether inoita basa risingaperi, kunyanya mukugadzirwa kweanokosha moter (yakagadziriswa moter), chinhu chakakosha uye chakakosha chinhu. Basa rakakosha remvura-solulable cellulose ecther vanonyanya kuve nematanho, imwe yakanakisa mvura, iyo iri pesvedzero yekuenderana uye yechitatu kudyidzana neiyo simende. Iyo yekuchengetwa kwemvura yemubatanidzwa ether inoenderana nemvura yekunyura kweiyo chigadziko cheshuwa, kuumbwa kweiyo dhudzi, iyo mvura yekudonha, uye nguva yekuisa yemvura. Kuchengetwa kwemvura kwemasero ether pachayo kunobva pane iyo solubility uye kushomeka kwemheremalose ether pachayo. Sezvo isu tese tinoziva, kunyangwe iyo cellulose molecular ine huwandu hukuru hwe hydratable hydratable yeHydratable yeHydratable Iko kugona kwehydration yeiyo hydroxyl mapoka chete hakuna kukwana kuvhara iyo yakasimba hydrogen zvisungo uye van der waals mauto pakati pemamorikisi. Naizvozvo, zvinongotsvaira asi hazvipfuuri mumvura. Kana iyo substituent ikasvitswa mumatehwe echinyakare Iyo yakakura iyo isiriyo, iyo yakakura chinhambwe pakati pemamorekuru. Kureba kwacho. Mhedzisiro yakakura yekuparadza maHydrogen zvisungo, iyo cellulose ether inova mvura-solulable mushure meCellulose LATTE uye mhinduro inopinda, inogadzira mhinduro yepamusoro-viscosity. Kana tembiricha ikasimuka, hydration yePolymer inopera simba, uye mvura pakati pemaketani inodzingwa. Kana iyo yekushomeka mhedzisiro yakaringana, mamorekuru anotanga kuunganidzwa, achigadzira matatu-matatu emhando network network gl uye akapetwa kunze.

Kazhinji, iyo yepamusoro viscosity, iri nani kuchengetedza kwemvura. Nekudaro, yepamusoro iyo viscosity uye yakakwira iyo smecular uremu, kuderera kunoenderana mukushushikana kwayo kunokanganisa kusasimba kwekushayiwa kwesimba. Yakakwira iyo viscosity, zvakanyatsojeka zvinokanganisa mudhaka, asi haina hukama zvakananga. Iyo yepamusoro iyo viscosity, iyo yakawanda viscous iyo mongwe yakanyorova, iri panguva yekuvakwa, inoratidzwa sekunamatira kune iyo scriper uye yakanyanya kuderera kune substrate. Asi hazvibatsiri kuwedzera simba rekuumbwa kweiyo yakanyorova dhaka pacharo. Munguva yekuvaka, kuita kwekurwisa-sag hakusi pachena. Pane kusapindirana, imwe yepakati uye yakaderera viscosity asi yakagadziridzwa methyl cellal celler maserimita kuita mukuvandudza simba rerudzi rwemutengesi.

Kuremedza uye iyo thisiotropy ye cellulose ether

Kune zvakare hukama hwakanaka hwemutsara pakati pehukama hweSEENT SAME uye DOSAGE YEMAHARA ECERULose EHER. Cellulose ether inogona kuwedzera kwazvo vhiza yemota. Iyo yakakura dosi, zvakanyatsonaka mhedzisiro. Yakakwira-viscosity cellulose ether mhinduro yemvura ine yakakwira thixotropy, iyo zvakare hombe hunhu hwe cellulose ether.

Kukakavara kunoenderana nedhigirii yePolymerization yeCellulose ether, mhinduro yekusimbisa, Shear rate, tembiricha nemamwe mamiriro ezvinhu. Iyo gelling midziyo yemhinduro yakasarudzika kuAlkyl cellelose uye yakagadziridzwa ayo yakagadziriswa. Iyo gelation zvivakwa zvine chekuita neyero yekutsiva, mhinduro yekusimbisa uye yekuwedzera. Kune hydroxylkyllk yakagadziridzwa inobva Zvekudzikiswa viscosity mc uye hpmc, 10% -15% solution inogona kugadzirira 5% yekugadziriswa kweCellulose ether yakanyorwa ne1% -2% mhinduro. Yakakwira molecular uremu cellulose ether ine yakanyanya kuremerwa kuita. Mumhinduro yakafanana, polymers ine huremu hwakasiyana hwemanyorerwe ane zvisizvo zvevakasiyana visikoka. Yakakwirira degree. Iyo target viscosity inogona chete kuwanikwa nekuwedzera huwandu hwakawanda hwehuwandu hwakareba hwemanyorerwe ecelose ether. Viscosity yayo ine zvishoma kutsamira pajecha ratehwe, uye iyo yepamusoro viscosity inosvika pakuvatisa viscosity, uye iyo inodiwa yekuwedzera huwandu idiki, uye iyo viscosity zvinoenderana nekubudirira kwekubudirira. Naizvozvo, kuti uwane kumwe kusimba, imwe huwandu hwe cellulose ether (kusunganidzwa kwemhinduro) uye mhinduro viscosity inofanira kuvimbiswa. Iyo tembiricha yemhedzisiro yemhindurowo zvakare inoderedza mutsara nekuwedzera kwekusangana kwemhinduro, uye geles pamhepo tembiricha mushure mekusvika pane imwe pfungwa. Iyo gelling yekuvhara yeHPMC yakakwira pakakwirira pamhepo tembiricha.

Kudzoka kwe cellulose ether

Basa rechitatu re cellulose ether kunonoka kugadzirwa kwehystem ye simenti. Cellulose ether endows dope neyakasiyana siyana zvinobatsira zvinhu, uye zvakare inoderedza kupisa kwehydration yekutanga yeSimende uye kunonoka iyo hydration deynamic maitiro eiyo simende. Izvi hazvina kunaka pakushandiswa kwemotokari munzvimbo dzinotonhora. Iyi mari yekudzorera inokonzerwa neyemushambadzi weCellulose ether mamorekuru pane hydration zvigadzirwa senge csh naCa (OH) 2. Nekuda kwekuwedzera kweiyo visikoka yemhinduro yemhinduro, iyo cellulose ether inoderedza kufamba kweiyi mhinduro, nekudaro kunonoka hydration maitiro. Iyo yepamusoro kusunganidzwa kwemheremelle ether mune mineral gel zvinhu, iyo inonyanya kutaura mhedzisiro yekunonoka kwehyration. Cellulose ether kwete chete kunonoka kuronga, asi zvakare kunonoka kuomesa kweiyo simende yemutumbi system. Iko kudzoreredzwa kwemasero emasero ether kunoenderana kwete chete pakurongeka kwayo muhurongwa hwemaminerari hwechemumoyo, asiwo pane zvemakemikari. Iyo yakakwira iyo degree remethylation yeHemc, iri nani kudzoreredzwa kwemasero e cellulose ether. Iyo chiyero chehydrophilic kutsiva kune inowedzera-inowedzera kutsiviwa kwekudzosera mari yakasimba. Nekudaro, iyo viscosity ye cellulose ether ine zvishoma mhedzisiro paSermin Hydration Kinetics.

MuMortar, cellulose ether inoita basa rekuchengeta mvura, kurira, kunonoka kwehystem hydration simba, uye kuvandudza mashandiro ekuvaka. Kuchengetwa kwemvura kwakanaka kunoita kuti skoment hydration yakawanda, inogona kuvandudza viscosity yakanyorova yeruboshwe, wedzera kusanganisa simba remutya, uye gadzirisa nguva. Kuwedzera cellulose ether kune manhamba ekupfira motsi anogona kuvandudza iyo yekupuruzira kana kupomerwa kuita uye yakasimba simba remutya. Naizvozvo, cellulose ether iri kunyatso kushandiswa seyakakosha anowedzera muyedzo yakagadzirirwa-yakavhenganiswa
