Wall stucco chikamu chakakosha chezvivakwa zvemazuva ano, ichipa yakanakisa uye inoyevedza kupera kumadziro. Ichi chinyorwa chinowanzo kuve nezvakasiyana-siyana senge simende, jecha nemvura. Zvisinei, kuwedzerwa kwe cellulose ether kuri kuwana mukurumbira nekuda kwezvimiro zvayo zvakasiyana, izvo zvinovandudza kushanda kwemadziro emadziro nenzira dzakawanda. Cellulose ethers ma hydrocolloids anotorwa kubva mumiti yemiti iyo inoshandiswa zvakanyanya sekuwedzera kwekushanda mumhando dzakasiyana dzekushandisa, kusanganisira madziro plaster formulations. Muchikamu chino, tinokurukura nezvebasa re cellulose ether mumadziro plaster magadzirirwo uye kuti angaite sei kuvandudza kunaka kwemadziro plaster.
Inovandudza processability uye kunyorova kunamatira
Rimwe remabasa akanyanya kukosha e-cellulose ethers mumadziro plaster formulations ndeyekuti inovandudza kushanda kweiyo plaster musanganiswa. Cellulose ethers inonyanya kunyungudika mumvura uye kana yawedzerwa kumusanganiswa wepurasita yemadziro inoumba musanganiswa une homogeneous uye wakagadzikana. Kuwedzera cellulose ethers kumusanganiswa we stucco kunonatsiridza kunamira kwemvura, zvichiita kuti zvive nyore kuisa stucco kumadziro.
Sezvo cellulose ether iri polima inonyungudika nemvura, inononotsa kunyudzwa kwemvura yepurasita yemudhuri uye nokudaro inonotsa kuomesa. Ichi chivakwa chinobvumira plaster kuti irambe ichishanda kwenguva yakareba, ichibvumira vavaki kuti vawane nzvimbo dzakapfava. Uku kunonoka kunyura kwemvura kunobatsirawo kuderedza kuputika uye kunatsiridza huwandu hwese hwemadziro plaster.
kuderedza shrinkage
Wall plaster inowanzoita kuderera kana ichioma, izvo zvinogona kukonzera kutsemuka nekumwe kukanganisa. Kushandiswa kwe cellulose ethers mu stucco formulations kunogona kuderedza kupera kwemadziro plaster. Cellulose ether inoumba homogeneous uye yakagadzikana musanganiswa nezvimwe zvikamu zvegypsum, iyo inobatsira kuderedza kuwanda kwemvura inodiwa mumusanganiswa.
Sezvo mvura iriyo inonyanya kukonzera shrinkage mumadziro plaster, kuderedza mvura yemukati kunobatsira kudzikisira. Kuwedzerwa kwe cellulose ethers kunobatsira kuchengetedza hunyoro mumusanganiswa westucco, nekudaro kuderedza kuderera kwese kwemadziro stucco.
Wedzera kubatana uye kushanduka
Cellulose ether inogona zvakare kuwedzera kunamira uye kuchinjika kwemadziro plaster. Cellulose ethers inowedzera kubatanidzwa kwese kwegypsum musanganiswa nekugadzira yakagadzikana uye homogeneous musanganiswa. Kuvapo kwe cellulose ether kunoitawo kuti musanganiswa weplaster uwedzere kushanduka, kuderedza dambudziko rekutsemuka uye zvimwe zvikanganiso. Pamusoro pezvo, cellulose ethers inopa kumwe kunyungudika kumapurasita emadziro, zvichiita kuti isanyanya kusimba.
Kuvandudza sag resistance
Sagging idambudziko rinowanzoitika panguva yekuvakwa kwemadziro emapurasita, kunyanya pamhepo yakatwasuka. Kuwedzera cellulose ether kumusanganiswa westucco kunogona kuvandudza kusaga uye kuita kuti stucco igadzikane panguva yekuvaka. Cellulose ethers inoumba musanganiswa wakafanana, wakagadzikana unobatsira kudzivirira plaster kubva pakutsvedza kubva kumadziro. Ichi chivakwa chinoita zvakare kuti plaster isarambe kutsemuka uye humwe hurema hunokonzerwa nekudonha.
Kuvandudza kudzivirira kwemvura
Cellulose ethers inogonawo kuvandudza kudzivirira kwemvura kwemapurasita emadziro. Sezvo cellulose ether ichiumba musanganiswa wakafanana uye wakagadzikana nemvura, inodzivirira mvura kupinda mupurasita. Ichi chivakwa chinoita kuti madziro emadziro arambe achidzivirira mvura, izvo zvakakosha kune nzvimbo dzakavhurika kumvura, senge yekugezera nekicheni.
kuderedza kuomesa nguva
Kuvapo kwe cellulose ethers mumadziro plaster formulations inogona zvakare kuderedza nguva yekuomesa yepurasita. Sezvo cellulose ether inononoka kunwa kwemvura yegypsum, inononoka kuomeswa, zvichiita kuti gypsum iome pamwero unodzorwa. Kuderedzwa kwenguva yekuomesa kunobatsira, kunyanya munzvimbo dzine hunyoro umo plaster inogona kutora nguva yakareba kuti iome.
mukupedzisa
Mukupedzisa, cellulose ethers zvakakosha zvinowedzera mumadziro plaster formulations. Iyo inosimudzira kushanda, kunyorova kunamatira, kubatana, kuchinjika, sag kuramba, kusamira kwemvura uye kuomesa nguva yemadziro plasters. Kushandiswa kwema cellulose ethers mumadziro plaster formulations imhinduro inodhura kune akawanda ematambudziko anowanikwa panguva yekuiswa kwemadziro plaster. Sezvo indasitiri yekuvaka iri kuramba ichikura, kushandiswa kwema cellulose ethers mumadziro plaster maumbirwo anotarisirwa kuwedzera nekuda kwezvimiro zvavo zvakasiyana uye mabhenefiti.
