Kugadzirwa kwegypsum-based self-leveling mortars kunoda kushandiswa kwezvinhu zvakasiyana-siyana, chimwe nechimwe chinokanganisa maitiro chaiwo echigadzirwa chekupedzisira. Chinhu chakakosha che self-leveling mortar is cellulose ether, iyo inokosha yekuwedzera.
Gypsum-based self-leveling mortars: mhedziso
Self-leveling dhaka chinhu chakasarudzika chekuvakisa chakagadzirirwa kunyorera pasi izvo zvinoda yakatsetseka, nhanho yepamusoro. Aya madhaka anowanzo sanganisira mabhaidha, aggregates uye akasiyana ekuwedzera kuti awane chaiwo maitiro ekuita. Gypsum chicherwa chechisikigo chinowanzo shandiswa seyekutanga bhainda mumadhaka ekuzvimisa nekuda kwezvimiro zvayo zvakasiyana, zvinosanganisira kuseta nekukurumidza uye kushanda zvakanaka.
Raw materials yegypsum-based self-leveling mortar:
1. Gypsum:
Kwakabva: Gypsum iminerari inogona kucherwa kubva kune zvakasikwa deposits.
Basa: Gypsum inoshanda seyakanyanya bhainda redhaka rinozvimisa. Inobatsira mukukurumidza kusimba uye kukura kwesimba.
2. Aggregation:
Kwakabva: Aggregate inotorwa kubva kumarara echisikigo kana dombo rakapwanyika.
Basa: Zviunganidzo, zvakaita sejecha kana matombo akatsetseka, zvinopa zvakawanda kudhaka uye zvinopesvedzera zvimiro zvayo zvemuchina, kusanganisira simba nekusimba.
3. Cellulose ether:
Kwakabva: Cellulose ethers inotorwa kubva kune yakasikwa cellulose masosi sehuni pulp kana donje.
Basa: Cellulose ether inoshanda se rheology modifier uye mvura-yekuchengetedza mumiririri kuti ivandudze kushanda, kunamatira uye kushanda kwese kwega-leveling mortar.
4. Yakakwirira-inoshanda yekudzikisa mvura mumiririri:
Kwakabva: Superplasticizers ma polymers ekugadzira.
Basa: Yakanyanya-inoshanda yekudzikisa mvura mumiririri inovandudza fluidity uye kushanda kwedhaka nekudzikisa zviri mukati memvura, zvichiita kuti zvive nyore kuisa uye nhanho.
5. Retarder:
Kwakabva: Retarders inowanzobva pane organic compounds.
Basa: Retarder inogona kudzikamisa nguva yekumisikidza yedhaka, kuwedzera nguva yekushanda uye kukurudzira maitiro ekuenzanisa.
6. Kuzadza:
Kwakabva: Mafirita anogona kuve echisikigo (senge limestone) kana ekugadzira.
Basa: Mafirita anobatsira kuhuwandu hwedhaka, kuwedzera huwandu hwayo uye kukanganisa zvivakwa zvakaita se density uye thermal conductivity.
7. Fiber:
Kwakabva: Fibers dzinogona kuva dzechisikigo (seg cellulose fibers) kana synthetic (eg polypropylene fibers).
Basa: Mafibhi anowedzera kusimba uye kushanduka kwesimba redhaka uye kuderedza njodzi yekutsemuka.
8. Mvura:
Kunobva: Mvura inofanira kuva yakachena uye yakakodzera kunwa.
Basa: Mvura yakakosha kune iyo hydration process ye plaster uye zvimwe zvinongedzo, zvichibatsira mukuvandudza kwesimba rematope.
Kugadzira Maitiro:
Kugadzirira kwezvinhu:
Gypsum inocherwa uye inogadziriswa kuti iwane hupfu hwakatsetseka.
Iyo aggregate inounganidzwa uye yakapwanyika kusvika kuhukuru hunodiwa.
Cellulose ethers inogadzirwa kubva kune cellulose masosi kuburikidza nemakemikari kugadzirisa.
musanganiswa:
Gypsum, aggregate, cellulose ethers, superplasticizer, retarder, fillers, fibers nemvura zvinoyerwa chaizvo uye zvakasanganiswa kuti zviwane musanganiswa wakafanana.
QC:
Iyo musanganiswa inosangana neyakaomesesa yemhando yekudzora kuyedzwa kuti ive nechokwadi chekuti inosangana neyakatsanangurwa kuenderana, simba uye mamwe maitiro ekuita.
Package:
Chigadzirwa chekupedzisira chinoputirwa mumabhegi kana mamwe midziyo yekugovera uye kushandiswa panzvimbo dzekuvaka.
mukupedzisa:
Kugadzirwa kwegypsum-based self-leveling mortars kunoda kunyatsosarudzwa uye kusanganiswa kwezvinhu zvakasvibirira kuti zvibudirire zvinodiwa. Cellulose ethers inoita basa rakakosha sezvinowedzera zvinovandudza kushanda, kunamatira uye kuita kwese kwedhaka. Sezvo indasitiri yekuvaka ichienderera mberi nekushanduka, kutsvagisa nekusimudzira mune zvesainzi zvekushandisa kunogona kutungamira kune imwe gadziriso mumadhaka ekuzvimisa, kusanganisira kushandiswa kwezvinowedzerwa zvekuwedzera uye zvinogara mbishi.
