Cement-based tile adhesives anoshandiswa zvakanyanya mukugadzira uye mukati mekugadzira basa. Iwo anoshandiswa kuchengetedza mataira kumadziro, pasi, uye dzimwe nzvimbo. Aya anonamira ane chinhu chakakosha chinoita kuti awedzere kushanda: hydroxypropyl methylcellulose (HPMC).
HPMC ndeye yakagadziridzwa cellulose polymer ine akawanda maindasitiri maapplication. Mumatairi anonamira, inoshandiswa seyakakora, inochengetedza mvura uye inonamira. Ihupfu chena kana chena, isina chepfu, isinganhuhwi uye isinganakidze.
Kana yakawedzerwa kune simenti-based tile adhesives, kushanda kwayo kunogona kuvandudzwa nenzira dzakawanda. Heano zvimwe zvikonzero nei HPMC iri chinhu chakakosha mune cementitious tile adhesives:
1) Inopa yakagadziridzwa processability
HPMC inovandudza kushanda nekugadzira simentitious mataira anonamira nyore kuisa nekupararira. HPMC inowedzera viscosity yekunamatira, ichiita kuti iwedzere kubatana uye nyore kushanda nayo. Iyo zvakare inoderedza kudonha, inova iyo yekunamatira inomhanya kana kudonha kubva pamusoro.
2) Kuvandudza kuchengetedza kwemvura
Cementitious tile adhesives nyore nyore kurasikirwa nehunyoro kune substrate iyo inoshandiswa kwairi. HPMC inobatsira kuwedzera kuchengetwa kwemvura kweanonamira, iyo yakakosha pakurapa kwakaringana kwekunamira. Ichi chimiro chinovimbisa kuti chinonamira chine hupenyu hwakareba uye chinogona kumira munyoro, kupisa uye zvimwe zvakatipoteredza. Izvi zvinonyanya kukosha kana tile yakaiswa munzvimbo dzakanyorova senge dzimba dzekugezera nekicheni.
3) Ane adhesion zviri nani
HPMC inonamira inoshanda iyo inosimudzira kubatanidza kuita kwesamende-based tile adhesives. Kana yakawedzerwa kune yakanamatira, inobatsira kusunga simenti uye zvimwe zvikamu zvekunamatira pamwe chete, zvichiita kuti zvive zvakakosha pakubata tile nezvimwe zvinhu kune substrate.
4) Deredza kuputika
Kutsemuka ndeimwe yezvinetso zvinowanzoitika nesamende-based tile adhesives. HPMC inogona kubatsira kuderedza kutsemuka nekuwedzera kuchinjika kweanonamira uye kuderedza shrinkage. Izvi zvinonyanya kukosha kana mataira akaiswa pane anobvisika nyore substrates sehuni kana simbi.
5) Kuvandudza kusimba
HPMC inogona kuvandudza kusimba kwesimende-based tile adhesives. Iyo inodzivirira kunamira kubva pakuputsika nekuda kwekusangana nehunyoro uye zvimwe zvakatipoteredza. Iyo inoderedzawo kuwanda kwe efflorescence inovaka pamusoro peiyo tile.
6) Wedzera kasi yakatarwa
HPMC inobatsira kukurumidzira kuseta kwesemende-based tile adhesives. Izvi zvakakosha kana nguva iri yezvakakosha uye iyo yekunamatira inoda kuseta nekukurumidza kuchengetedza tile yakachengeteka munzvimbo.
7) Deredza mukana wekuputika kwegrout
HPMC inobatsira kuderedza mukana wekupwanya grout. Kuputika kwegrout kunoitika apo kufamba kwe substrate kunoputsa chisungo pakati pe tile uye inonamatira. HPMC inogona kuita kuti inonamira iwedzere elastic, iyo inobatsira kutora substrate kufamba uye kudzivirira grout kutsemuka kubva pakuumbwa.
Muchidimbu, HPMC chinhu chakakosha chesimende-based tile adhesives. Hunhu hwayo hwakawanda hunoita kuti ive chikamu chakakosha chechero chinonamira chinoshandiswa kuisa mataira. Inoita basa rinokosha mukugara, kushanda uye kunamatira kwekunamatira. Kana yawedzerwa kune simende-based tile adhesives, inova nechokwadi chekuita kwakanyanya, hupenyu hurefu uye kugutsikana kwevatengi.
