Ma cellulose ethers amagwiritsidwa ntchito nthawi zambiri mumatope a gypsum kuti apititse patsogolo zinthu zawo. Gypsum mortar ndi matope osakaniza owuma omwe amagwiritsidwa ntchito kwambiri popanga ntchito zosiyanasiyana, monga kudzaza mipata ndi zolumikizira, kukonza ming'alu ya makoma ndi denga, ndikupanga zokongoletsera zokongoletsera. Kuonjezera ma cellulose ethers ku matope a gypsum kumatha kukulitsa magwiridwe antchito ake, kusunga madzi, kukhazikitsa nthawi ndi mphamvu.
1. Kuwongolera magwiridwe antchito
Ubwino umodzi wogwiritsa ntchito ma cellulose ethers mu matope a gypsum ndikuti umapangitsa kuti kusakaniza kukhale kosavuta. Kugwira ntchito kumatanthauza kumasuka komwe kungasakanizike, kunyamulidwa, ndi kuyika pamwamba. Pogwiritsa ntchito ma cellulose ethers, matope a gypsum amakhala amadzimadzi komanso osavuta kufalikira, motero amachepetsa kuchuluka kwa ntchito yofunikira pakusakaniza ndikugwiritsa ntchito. Izi ndizofunikira makamaka pama projekiti akuluakulu omanga pomwe nthawi ndiyofunikira komanso kuthamanga kwa ntchito kumakhudza zokolola.
2. Limbikitsani kusunga madzi
Ubwino wina wogwiritsa ntchito ma cellulose ethers mu matope a gypsum ndikuti umathandizira kusunga madzi osakaniza. Izi ndizofunikira chifukwa matope a gypsum amakonda kuuma mwachangu, makamaka pakauma komanso kotentha. Pogwiritsa ntchito ma cellulose ethers, kusungidwa kwa madzi kwa kusakaniza kumawonjezeka, kutanthauza kuti matope amakhalabe onyowa kwa nthawi yaitali, kuti azitha kugwira ntchito mosavuta komanso kuti asawonongeke kapena kuphulika msanga. Izi ndi zothandiza m'madera omwe mulibe chinyezi chochepa kapena pamene dothi liyenera kuikidwa pamalo oima pomwe mphamvu yokoka imapangitsa kuti kusakaniza kutsetsereka.
3. Kulamulira nthawi coagulation
Ma cellulose ether amawonjezedwa ku matope a gypsum kuti aziwongolera nthawi yake. Kukhazikitsa nthawi ndi nthawi yomwe imatengera matope a gypsum kuti asinthe kukhala olimba. Nthawi imeneyi ndi yofunika kwambiri pa ntchito yomanga iliyonse chifukwa imatsimikizira kuti ogwira ntchito ayenera kumaliza kwa nthawi yayitali bwanji zinthuzo zisanakhale zovuta kuzigwira. Ma cellulose ether amachepetsa nthawi yoyika pulasitala, zomwe zimapatsa antchito nthawi yochulukirapo yopaka ndi kuumba zinthuzo zisanawume.
4. Wonjezerani mphamvu
Kuonjezera cellulose ether ku gypsum mortar kungathandizenso mphamvu ya mankhwala omalizidwa. Izi zili choncho chifukwa ma cellulose ethers amapanga maukonde a mesh mkati mwa matope a gypsum, zomwe zimapangitsa kuti zisawonongeke, kupindika kapena kusweka. Izi ndizothandiza pama projekiti omanga pomwe zinthu zomalizidwa zimakumana ndi zonyamula ma voltage okwera, monga makina apansi, nyumba zapadenga kapena makoma a mafakitale.
5. Kugwirizana kwabwino
Chinthu china chofunika kwambiri cha ma cellulose ethers mu matope a gypsum ndikugwirizana bwino ndi zigawo zina za osakaniza. Cellulose ether ndi polima wachilengedwe yemwe amagwirizana ndi zinthu zina zambiri zomwe zimagwiritsidwa ntchito mumatope a gypsum, monga retarders, superplasticizers ndi air-entraining agents. Izi zimathandiza omanga ndi omanga kuti apange zosakaniza za matope a gypsum kuti akwaniritse zofunikira zomanga.
Pomaliza
Cellulose ether ndi chowonjezera chachikulu mu matope a gypsum, omwe amatha kupititsa patsogolo ntchito, kusunga madzi, kuika nthawi, mphamvu ndi kugwirizana kwa matope a gypsum. Amagwiritsidwa ntchito kwambiri pantchito yomanga kupanga zinthu zamtengo wapatali, zotsika mtengo komanso zokhazikika zomwe zimakwaniritsa zofunikira zantchito yomanga masiku ano. Pogwiritsa ntchito ma cellulose ethers mu matope a gypsum, omanga ndi omanga atha kuwonjezera zokolola, zogwira mtima komanso moyo wautali wazinthu zomwe zamalizidwa, kuzipanga kukhala gawo lofunikira pakumanga kwamakono.
