Kusimba kwe cellulose ether

Cellulose etherInopa dhaka rakanyorova simba rakanaka, inogona kuwedzera kugona kwedhaka rakanyorova uye pasi pevhu, inovandudza kushanda kwedhaka risingatsvedze, rinoshandiswa zvakanyanya mudhaka replaster, system yekudzivirira kunze uye dhaka rekubatanidza zvidhinha. Kusimba kwe cellulose ether kunogonawo kuwedzera kufanana uye kugona kwekudzivirira kupararira kwezvinhu zvitsva zve simende, kudzivirira kupatsanurwa, kuparadzaniswa uye kubuda ropa kwedhaka nekongiri, inogona kushandiswa mu faibha kongiri, kongiri iri pasi pemvura uye kongiri inozvibatanidza.

Cellulose etherinowedzera viscosity yezvinhu zvakagadzirwa nesimende kubva mukunaka kwemhinduro ye cellulose ether. Kazhinji shandisa "viscosity" iyi metric kuongorora viscosity yemhinduro ye cellulose ether, viscosity ye cellulose ether inowanzo kureva huwandu hwakati (2%) hwemhinduro ye cellulose ether, tembiricha (20 ℃) ​​uye shear rate (kana kutenderera kumhanya, senge 20 RPM), nezvinodiwa nechishandiso chekuyera, senge viscosity inotenderera yakayerwa viscometer. Viscosity iparameter yakakosha yekuongorora mashandiro e cellulose ether ne cellulose ether, viscosity yemhinduro yakakwira, viscosity yesimbi yesimbi yesimbi iri nani, viscosity yesimbi yesimbi inogona, sag resistance uye resistance kune simba rekupararira, asi kana viscosity yakakura zvakanyanya, inogona kukanganisa kufamba kwesimbi yesimbi yesimbi uye maneuverability (senge kuvaka plaster mortar adhesive plaster). Saka, viscosity ye cellulose ether inoshandiswa musimbi yakasanganiswa yakaoma inowanzo kuve 15,000 ~ 60,000 Mpa. s-1, uye viscosity ye cellulose ether inofanirwa kunge yakaderera kune self-leveling mortar uye self-compactconcrete ine zvinodiwa zvakanyanya zvekuyerera. Pamusoro pezvo, thickening effect ye cellulose ether ichawedzera kudiwa kwemvura kwezvinhu zvakagadzirwa nesimende, nokudaro zvichiwedzera kubuda kwemortar. Viscosity ye cellulose ether solution inoenderana nehuremu hwemamorekuru (kana dhigirii repolymerization) uye huwandu hwe cellulose ether, tembiricha yemhinduro, shear rate, uye nzira yekuyedza. Kana polymerization degree ye cellulose ether yakakwira, huremu hwemamorekuru hwakawedzera, viscosity ye aqueous solution yayo yakakwira; Kana dosage (kana concentration) ye cellulose ether yakakwira, viscosity ye aqueous solution yayo yakakwira, asi mukushandiswa inofanira kutarisisa kusarudzwa kwedosage yakakodzera, kuitira kuti isasanganiswe zvakanyanya, inokanganisa mashandiro emortar ne concrete; Kufanana nezvimwe zvinwiwa zvakawanda, viscosity ye cellulose ether solution ichaderera nekuwedzera kwetembiricha, uye kana cellulose ether yakakwira, mhedzisiro yetembiricha inowedzera; Mushonga weCellulose ether unowanzova muviri wepseudoplastic une hunhu hwekuchekerera ganda. Kana kucheka ganda kwacho kwakakwira, viscosity inoderera.

Saka, kubatana kwedhaka kuchaderedzwa nesimba rekunze, izvo zvinobatsira pakuvaka dhaka, zvichiita kuti dhaka rishande zvakanaka uye ribatane. Zvisinei, mhinduro ye cellulose ether icharatidza hunhu hweNewtonian fluid kana huwandu hwacho hwakaderera uye viscosity iri diki kwazvo. Kana huwandu hwacho huchiwedzera, mhinduro yacho inounza hunhu hwepseudoplastic fluid zvishoma nezvishoma, uye kana huwandu hwacho hwakakwira, pseudoplastic inonyanya kuoneka.
