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 nehydrogen bond pakati pe cellulose ether molecule uye mvura molecule uye mhepo chiito che cellulose ether molecule, chaizvoizvo, inotora chikamu chehydrogen bond mu cellulose ether molecular chain uye inoderedza kupindira kwe cellulose ether, iyo inoderedza kuchengetwa kwemvura uye kukwanisa 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 viscosity yakakwira zvakanyanya kupfuura tekinoroji inodiwa viscosity, chikamu ichi chakatsivawo 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 eketani akareba e-cellulose ether cross-link uye ave net-like, iyo inokanganisa kukurumidza kwe cellulose ether kuumbwa kwefirimu uye mamiriro emufirimu, nokudaro inokanganisa basa re cellulose ether mudhaka, iyo yakananga-inoona pesvedzero ndeyokuti: simba rekunamatira rinoputika rakashanduka pasi pemamiriro ega ega ekurapa; nguva yokuisa dhaka yakawedzerwa.
1.Pasi pemamiriro ekurapa akajairwa, kuwedzerwa kwetackifier uye cellulose ether pasina tackifier mukugadzira maitiro kune imwe mhedzisiro pane inomira inonamira simba re ceramic tile inonamira, zvigadzirwa zvinowedzerwa ne tackifier mukugadzira maitiro zvine akanyanya kusimba ekunamira simba.
2.Muchikamu chekudzivirira kwemvura, simba rekunamatira resimbi yekeramic tile adhesive ne cellulose ether yakawedzera tackifier mukugadzirwa kwekugadzirwa kwakaipa kudarika iyo yechigadzirwa pasina tackifier mune yakajairika kugadzirwa kwemaitiro, iyo cellulose ether ine tackifier inokanganisa kudzivirira kwemvura kweadhesive 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 iyo inoita kuti cellulose ether aqueous solution ive nepamusoro steric chipingamupinyi, iyo inoratidzwa kuva yakakwirira mukuedzwa, asi kuvapo kwetackifier kunobata zvinhu zvakawanda zvinokosha zvekushandiswa kwe 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 kuviscosity, zvichiita kuti mamwe mabhizinesi ekugadzira cellulose ether awedzere viscosity kuburikidza nekuwedzera zvinhu kuti zvizadzise zvinodiwa nevagadziri vematope, uye rudzi urwu rwezvigadzirwa zvinongova nehupamhi hunoonekwa, kuita kwayo kwakadzama kwakakodzera kutariswa kwevashandisi, uye iyo inowoneka yakakwira viscosity inoumbwa nekuwedzera viscosity "yakaderera viscosity". izvo vagadziri vematope vanotarisira, asi hazvipo hazvo. 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.
