Mune yakagadzirira-yakavhenganiswa dhaka, chero bedzi zvishomacellulose etherInogona kuvandudza zvakanyanya kuita kweiyo yakanyorova motokari, inogona kuonekwa kuti cellulose ether itsvenyi huru iyo inokanganisa kuita kwekuvaka kwemutumbi.
Kusarudzwa kwemarudzi akasiyana, zvisizvo zvevakasiyana, size dzakasiyana-siyana dze viscosity uye kuwedzera kwema cellulose zvine mano akasiyana pakuvandudzwa kwekuita kweiyo yakaoma poda. Parizvino, zvakawanda masonry uye kupururudza motsi ane basa rekuchengetedza mvura, uye mvura slurry ichaparadzaniswa mushure memaminitsi mashoma ekumira. Saka zvakakosha kwazvo kuwedzera cellulose ether mumarara.
Kuchengeta mvura
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.
Mukugadzirwa kwezvinhu zvekuvakisa, kunyanya kuoma poda dowder, cellulose ether inoita basa risingaperi, kunyanya mukugadzirwa kweanokosha moter (yakagadziriswa moter), chinhu chakakosha uye chakakosha chinhu.
Iyo viscosity, dosage, ambient tembiricha uye molecular chimiro che cellulose ether ane pesvedzero huru pakubata kwayo kwemvura. Mumamiriro ezvinhu mamwechete, iyo yakakura iyo visikopo ye cellulose ether, iri nani kuchengetwa kwemvura; Iyo yakakwira dosage, iri nani kuchengetwa kwemvura. Kazhinji, chidiki chidiki che cellulose ether chinogona kuvandudza kudzikisira kwemvura kune dhaka. Pakasvika dosage ichisvika pane imwe nguva yekuchengetwa kwemvura inowedzera, maitiro ehuwandu hwekuchengetwa kwemvura anoregedza; Kana iyo ambure tembiricha ichisimuka, kuchengetwa kwemvura kwemusangano ether kazhinji kunowanzo kuderera, asi vamwe cellulose ma cellulose vaine kuchengetedzwa kwemvura zviri nani pasi pemamiriro ekunze ekushisa; Machira ane madhigirii akadzika ezvekutsiva vegan ether ane mari yekuchengetedza mvura.
Iyo hydroxyl boka pane cellulose ether molecule uye okisijeni pane iyo yekubatanidza inoshamwaridzana nemamolekhodhi yemvura kuti abatanidze mvura yehydrogen, nekudaro ichitamba basa rakanaka mukuchengetwa kwemvura; Mamolekhou emvura uye cellulose ether molecular keteni inobvumidza mamalekhollencules yemvura kuti ivhu macromolecular. Cellulose Ether inovandudza iyo nyowani slement slurry iyo rateological zvivakwa, osmotic network kana iyo firimu-inoumba midziyo ye cellulose ether inotadzisa kusiyana kwemvura.
kuremedza uye iyo thixotropy
Cellulose etherInopinda muguruva rakanyorova neakanakisa viscosity, izvo zvinogona kuwedzera zvakanyanya kugona kwekurongedza pakati pehunyoro hwemucheka uye chirahwe cheshuwa, uye kugadzirisa masangano ekurwisa-kupenga. Iyo inoshandiswa zvakanyanya mulastering motsi, zvidhinha maruva marara uye kunze kwemadziro ekunze system system. Mhedzisiro inoshamisa ye cellulose ether inogonawo kuwedzera iyo anti-kupararira kugona uye kudzivisa kusagadzikana, uye inogona kushandiswa mufiriji kongiri, pasi pemvura concrete uye yekuzvibata-converting kongiri.
Iko kukonzeresa simba re cellulose ether pa coment-based zvigadzirwa zvinobva kune viscosity ye cellulose erthime. Pasi pemamiriro ezvinhu akafanana, iyo yekukwirira kwemasangano e cellulose ether, zviri nani zvisizvo zvezvinyorwa zvakasarudzika, asi kana visikoity yakakwira kwazvo, ichakanganisa iyo yezvinhu (sekunonamira banga ripi). Kuzvibata-kuyambuka dhaka uye kuzvimiririra kongiri, kunoda yakakwirira fluidity, inoda viscosity yakaderera ye cellulose ether. Uye zvakare, iyo inoshamisa mhedzisiro ye cellulose ether ichawedzera iyo yemvura inodiwa yezvinhu zvemukati-zvakavakirwa uye wedzera gobvu remuumbi.
Yakakwira-viscosity cellulose ether mhinduro yemvura ine yakakwira thixotropy, iyo zvakare hombe hunhu hwe cellulose ether. Mhinduro dzemumhepo dze methyl cellulose kazhinji dzine pseudoplastics uye isina-thixotropic fluidity pazasi payo its gleng tembiricha, Pseudoplasticality inowedzera neyekuwedzera uremu kana kusunganidzwa kwemheremelle ether, zvisinei nerudzi rwetsiva uye degree rekutsiva. Naizvozvo, mheremalose etana emagrosity gracosity giredhi, hpmc, hemc, inogara ichiratidza zvimwe zvinhu zvechitsidzo kwenguva yakareba sekusangana uye tembiricha inogara ichichengetwa nguva dzose. Matura emhando ikagadzirwa kana tembiricha yamutswa, uye zvakanyanya thisiotropic inoyerera inoitika.
Yakanyanya kuderera uye yakaderera viscosity cellulose ana anairatidzira thixotropy kunyangwe pazasi pegomba tembiricha. Ichi chivakwa chinobatsira zvikuru kugadzirisa kwekuwedzera uye kusekerera mukuvakwa kwekuvaka moter. Zvinoda kutsanangurwa pano iyo yakakwira viscosity ye cellulose ether, iko zviri nani kuchengetwa kwemvura, asi iyo inoenderana nehukama hwemaCellulose ether, uye inoenderana nekukanganiswa kwayo, iyo ine yakaipa kukonzeresa kusimba kwemotokari uye kuita kwekuvaka.
Mhepo-yekupinza
Cellulose ether ine zviri pachena mweya-yekupindira inokanganisa pane yakachena cement-yakavakirwa zvinhu. Cellulose ether ine ese mapoka ehydrophilic (hydroxyl mapoka, emagetsi emapoka) uye mapoka e hydrophobic (methyl mapoka, denderedzwa nemhepo, nekudaro ine mhepo-yekupindirana. Mhepo-yekupindira yemari ye cellulose ichabereka "bhora" maitiro, ayo anogona kuwedzera kupatsanurana uye nekutsvedza kwemunyeredzi panguva yekuvhiringidza, iyo inokodzera kupararira kwemotokari; Izvo zvichawedzerawo kubudiswa kwemutya, kuderedza mari yekugadzira yemota; Asi ichawedzera rorosimba kwechinhu chakaomeswa uye kuderedza michina yayo michina yakadai sesimba uye elastic modulus.
Sechikadzi, cellulose ether ine yakanyorova kana yekuisa mbozita pane simende zvidimbu, izvo zvinowedzera midziyo yekukwenenzverwa pamwe chete nemhepo, asi isingakoshe simba ichaderedza fluidity. Mhedzisiro yehunhu kusanganiswa kwekusanganisa kwepasirese uye kwakakora mhedzisiro. Kazhinji, kana zviri mukati meCellulose ether zvakanyanyisa kuderera, iko kugona kukuru kupurasitiki kana kuderedzwa kwemvura; Kana zvirimo zvakakwira, mhedzisiro yemasero e cellulose ether inowedzera nekukurumidza, uye iyo yemhepo-inopinda mhedzisiro inowanzogutsa. Saka zvinoratidza sekukanganisa kwakasiyana kana kuwedzera kwekuda kwemvura.
kudzokera
Cellulose etherNdichawedzera nguva yekugara yeiyo coment pasita kana dhaka, uye kunonoka kuyamwisa nguva yekuvhenekerwa, kunatsiridza kuwirirana kwerukova uye kurasikirwa nekongiri nekufamba kwenguva, asi zvinogona kukonzerawo kuvaka kwakanonoka.
