Cellulose ethers, kunyanya hypromellose ethers, zvinhu zvakakosha zvemamortar ekutengeserana. Kune cellulose ether, viscosity yayo chiratidzo chakakosha chemakambani ekugadzira mortar, viscosity yakakura yave chinhu chikuru chinodiwa neindasitiri yemortar. Nekuda kwesimba retekinoroji, maitiro nemidziyo, zvakaoma kuvimbisa viscosity yakawanda yemumba.ether ye cellulosezvigadzirwa kwenguva yakareba. Cellulose ether inoshandiswa semushonga unochengetedza mvura, unosimbisa uye unosunga muzvigadzirwa zvemortar, izvo zvine simba guru pakushanda, kunyorova, nguva yekushanda uye maitiro ekuvaka emortar system. Mabasa aya anonyanya kuitwa nehydrogen bond pakati pe cellulose ether molecule newater molecule uye kutenderera kwe cellulose ether molecule, kutaura zvazviri, inotora chikamu chehydrogen bond mu cellulose ether molecular chain uye inopedza simba rekupindirana kwe cellulose ether, izvo zvinoderedza simba rekuchengetedza mvura uye kugona kunyorova kwe cellulose ether. Vagadziri vemortar havanzwi pfungwa iyi, kune rumwe rutivi, zvigadzirwa zvemortar zvemumba zvichiri zvakaoma, hazvisati zvanyatso tarisa padanho rekushanda, kune rumwe rutivi, tinosarudza kuti viscosity yakakwira zvakanyanya kupfuura viscosity inodiwa yehunyanzvi, chikamu ichi chakaripwawo nekurasikirwa kwekuchengetedza mvura, asi mukunyorova kunokuvadzwa.
Kushanda kwemortar kunokanganiswa ne cellulose ether ine adhesive extractant mukugadzirwa, muchinyorwa chino, musiyano wesimba re tensile adhesive pakati pe cellulose product ne cellulose ether product yakawedzerwa ne tackifier mu ceramic tile adhesive wakasimbiswa nekuyedza. Tackifier rudzi rwezvinhu zvakawedzerwa nevamwe vagadziri ve cellulose ether kuitira kutsiva kushomeka kwetekinoroji yekugadzira, tekinoroji uye michina. Kuvapo kwe tackifier kunoita kuti mamorekuru marefu e cellulose ether cross-link ave net-like, izvo zvinokanganisa kumhanya kwekuumbwa kwe cellulose ether film uye mamiriro efirimu, nokudaro zvichikanganisa basa re cellulose ether mumortar, pesvedzero yekutarisa zvakananga ndeyekuti: simba re tensile adhesive rakachinja pasi pemamiriro ese ekugadzirisa; nguva yekugadzika kwemortar inowedzera.
1. Pasi pemamiriro ekurapa akajairwa, kuwedzerwa kwetackifier ne cellulose ether isina tackifier mukugadzirwa kwayo kune mhedzisiro yakati pasimba rekunamira kwe ceramic tile, zvigadzirwa zvinowedzerwa netackifier mukugadzirwa kwayo zvine simba rakawanda rekunamira kwe tensile.
2. Panyaya yekudzivirira mvura, simba rekunamira kwe ceramic tile adhesive ine cellulose ether yakawedzerwa tackifier mukugadzirwa kwayo rakaipa kupfuura remuchina usina tackifier mukugadzirwa kwayo kwakajairika, cellulose ether ine tackifier inokanganisa kudzivirira mvura kwe tile adhesive.
3. Panyaya yenguva yekuiswa kwemhepo,ether ye cellulosene tackifier yakashandiswa mukunamira mataira, simba rayo rekunamira raive rakaderera pane remuchina usina tackifier, uye nguva yekuvhura yakapfupikiswa.
4. Kana iri nguva yekuisa, kumhanya kwekunamira kwe cellulose ether ceramic tile adhesive pasina kuwedzera tackifier pasi pemaitiro ekugadzirwa kwakajairika kunokurumidza. Muchidimbu, kuvapo kwetackifier, iyo inoshanda nekubatanidza cross-linking inoita kuti cellulose ether aqueous solution ive nedambudziko re steric, iro rinoratidzwa kuti rakakwirira mukuyedza, asi kuvapo kwetackifier kunokanganisa maitiro mazhinji akakosha ekushandisa cellulose ether, akadai sekudzivirira mvura, nguva yekuvhura, kunyorova nezvimwewo. Kutaura zvazviri, viscosity ndeimwe yema indexes ekushanda kwe cellulose ether, viscosity haisi index yakakosha yekushanda kwakazara kwe cellulose ether, asi mhando uye zviri mukati memapoka zvinofanirwa kuve chinangwa chevagadziri vemortar.
5. Izvi zvinokonzerwawo nekuti vagadziri vemadhaka vanonyanya kutarisisa kusviba, zvichiita kuti mamwe makambani ekugadzira ether ye cellulose awedzere kusviba kuburikidza nezvimwe zvinhu kuti zvienderane nezvinodiwa nevagadziri vemadhaka, uye rudzi urwu rwezvigadzirwa rune kusviba kwakanyanya, mashandiro arwo akazara anofanirwa kutariswa nevashandisi, uye kusviba kwakanyanya kunoonekwa nekuwedzera kusviba hakugone kuwana dzidziso ye "High viscosity low content" iyo vagadziri vemadhaka vanotarisira, asi haipo zvechokwadi. Kuti vasarudze ether ye cellulose, inova chinhu chakakosha mudhaka, makambani edhaka ari kutsvaga mhando yepamusoro uye yakagadzikana anofanira kuziva rumwe ruzivo rwuri shure, izvi zvichabatsira vagadziri kugadzira zvigadzirwa zvine mashandiro epamusoro, kuve nechokwadi chekugadzikana kwemhando yechigadzirwa.
