Cellulose ethers, kunyanya hypromellose ethers, zvakakosha zvikamu zvekutengesa madhaka.Kune cellulose ether, viscosity yayo indekisi yakakosha yemabhizinesi ekugadzira dhaka, yakakwira viscosity yave kuda kudiwa kweindasitiri yedhaka.Nekuda kwesimba re tekinoroji, maitiro uye zvishandiso, zvakaoma kuvimbisa iyo yakakwira viscosity yepambacellulose etherzvigadzirwa kwenguva yakareba.Cellulose ether inoshandiswa seyekuchengetedza mvura, thickener uye binder mune zvigadzirwa zvedhaka, iyo ine simba guru pakushanda kwekushanda, wet viscosity, nguva yekushanda uye nzira yekuvaka yedhaka system.Aya mabasa anonyanya kuitwa neiyo hydrogen bond pakati pe cellulose ether molecule uye mvura molecule uye mhepo chiito che cellulose ether molecule, kutaura zvazviri, inotora chikamu chehydrogen bond mu cellulose ether molecular chain uye inoderedza kupindira kwe cellulose ether, iyo inoderedza kuchengetwa kwemvura uye kugona kunyorova kwe cellulose ether.Vagadziri vematope kazhinji havanzwi pfungwa iyi, kune rumwe rutivi, zvigadzirwa zvevhu zvemumba zvichiri kuomarara, hazvisati zvave kungwarira kutarisisa danho rekushanda kwekushanda, kune rumwe rutivi, isu tinosarudza iyo viscosity yakanyanya kukwirira. kupfuura tekinoroji inodiwa viscosity, chikamu ichi chakabhadharawo kurasikirwa kwekuchengetedza mvura, asi mukunyorova kwakakuvadzwa.
Kuita kwedhaka kunokonzerwa ne cellulose ether ine adhesive extractant mukugadzirwa kwekugadzira, mubepa rino, mutsauko wekusimba kwekunamira kwesimba pakati peselulosi chigadzirwa uye cellulose ether chigadzirwa chakawedzerwa ne tackifier mu ceramic tile adhesive yakasimbiswa nekuedza.Tackifier imhando yezvinhu zvakawedzerwa nevamwe vanogadzira cellulose ether kuitira kuti vagadzirise kushomeka kwehunyanzvi hwekugadzira, tekinoroji uye michina.Kuvapo kwetackifier kunoita kuti mamorekuru echeni refu e cellulose ether cross-link uye ave net-like, izvo zvinokanganisa kukurumidza kwe cellulose ether kuumbwa kwefirimu uye mamiriro emufirimu, nokudaro zvichikanganisa basa re cellulose ether mudhaka, iyo yakananga- pesvedzero yekuona ndeiyi: simba rekunamira rachinja pasi pemamiriro ega ega ekurapa;nguva yokuisa dhaka yakawedzerwa.
1.Pasi pemamiriro ekurapa akajairwa, kuwedzera kwetackifier uye cellulose ether isina tackifier mukugadzira maitiro kune imwe mhedzisiro pakusimba kunonamira kweceramic tile adhesive, zvigadzirwa zvinowedzerwa ne tackifier mukugadzira maitiro zvine akanyanya kusimba ekunamira simba. .
2.Muchikamu chekudzivirira kwemvura, kusimba kwekunamatira kweceramic tile adhesive ne cellulose ether yakawedzera tackifier mukugadzirwa kwekugadzirwa kwakaipa kupfuura iyo yechigadzirwa isina tackifier mune yakajairwa kugadzirwa maitiro, cellulose ether ine tackifier inokanganisa mvura. kushorwa kwekunamatira tile.
3.Panyaya yenguva yekuseta mhepo,cellulose etherine tackifier yakashandiswa mukunamatira mataira, simba rayo rekunamatira raive rakaderera pane iro rechigadzirwa chisina tackifier, uye nguva yekuvhura yakapfupikiswa.
4. Kana iri nguva yekuisa, kukurumidza kuporesa kwe cellulose ether ceramic tile adhesive pasina kuwedzera tackifier pasi pemaitiro ekugadzirwa kwemaitiro inokurumidza.Muchidimbu, kuvapo kwetackifier, iyo-cross-linking action inoita kuti cellulose ether aqueous solution ive nepamusoro steric chipingamupinyi, iyo inoratidzwa seyakakwira muyedzo, asi kuvepo kwetackifier kunokanganisa akawanda akakosha ekushandisa e cellulose. ether, zvakadai sekudzivirira mvura, nguva yekuvhura, kunyorova uye zvichingodaro.Kutaura zvazviri, viscosity inongova imwe chete yezvinyorwa zvekushanda zve cellulose ether, viscosity haisi iyo inokosha indekisi yekushanda kwakazara kwe cellulose ether, asi rudzi uye zvinyorwa zvemapoka zvinofanira kuva zvinotarisa zvevagadziri vematope.
5.Izvo zvakare nekuti vanogadzira dhaka vanonyanya kutarisisa kune viscosity, zvichiita kuti mamwe mabhizinesi ekugadzira cellulose ether awedzere viscosity kuburikidza nekuwedzera zvinhu kuti zvizadzise zvinodiwa nevagadziri vematope, uye rudzi urwu rwezvigadzirwa zvinongove nepamusoro-soro inooneka viscosity, yakazara. kuita kwakakodzera kutariswa kwevashandisi, uye iyo inooneka yakakwira viscosity inogadzirwa nekuwedzera viscosity haigone kuzadzisa iyo "High viscosity yakaderera yemukati" dzidziso inotarisirwa nevagadziri vematope, asi haipo.Kuti usarudze cellulose ether, inova chinhu chakakosha mbishi mudhaka, mabhizinesi edhaka ari kutsvaga yakakwira uye yakagadzikana mhando inoda kuziva rumwe ruzivo kumashure, izvi zvichave zvakanaka kune vanogadzira kugadzira zvigadzirwa zvepamusoro-soro, kuve nechokwadi chekugadzikana kwechigadzirwa.
