Kupanga matope odzipangira okha a gypsum kumafuna kugwiritsa ntchito zipangizo zosiyanasiyana, zomwe zimakhudza katundu wina wa mankhwala omaliza. Chigawo chofunikira cha matope odziyimira pawokha ndi cellulose ether, chomwe ndi chowonjezera chofunikira.
Zodzikongoletsera za Gypsum: mwachidule
Tondo wodziyimira pawokha ndi zida zomangira zapadera zomwe zimapangidwira pansi zomwe zimafunikira malo osalala komanso osalala. Mitondo iyi nthawi zambiri imakhala ndi zomangira, zophatikizika ndi zowonjezera zosiyanasiyana kuti zikwaniritse magwiridwe antchito. Gypsum ndi mchere wachilengedwe womwe umagwiritsidwa ntchito kwambiri ngati chomangira matope odziyimira pawokha chifukwa cha mawonekedwe ake apadera, kuphatikiza kukhazikika mwachangu komanso magwiridwe antchito abwino kwambiri.
Zida zopangira matope a gypsum-based self-leveling mortar:
1. Gypsum:
Gwero: Gypsum ndi mchere womwe ukhoza kukumbidwa kuchokera kuzinthu zachilengedwe.
Ntchito: Gypsum imakhala ngati chomangira chachikulu pamatope odziyika okha. Imathandizira kulimbitsa mwachangu komanso kukulitsa mphamvu.
2. Kuphatikiza:
Gwero: Aggregate amachokera kuzinthu zachilengedwe kapena mwala wophwanyidwa.
Udindo: Zophatikizika, monga mchenga kapena miyala yabwino, zimapereka zochuluka kumatope komanso zimakhudza makina ake, kuphatikiza mphamvu ndi kulimba.
3. Ma cellulose ether:
Gwero: Ma cellulose ether amachokera kuzinthu zachilengedwe zama cellulose monga zamkati kapena thonje.
Ntchito: Cellulose ether imagwira ntchito ngati rheology modifier ndi wothandizira madzi kuti apititse patsogolo kugwira ntchito, kumamatira komanso kugwira ntchito kwathunthu kwa matope odzipangira okha.
4. Njira yochepetsera madzi kwambiri:
Gwero: Superplasticizers ndi ma polima opangira.
Ntchito: Njira yochepetsera madzi yogwira ntchito kwambiri imapangitsa kuti matope asamayende bwino pochepetsa kuchuluka kwa madzi, kupangitsa kuti ikhale yosavuta kuyiyika komanso kusanja.
5. Wobwezera:
Gwero: Ma retarders nthawi zambiri amachokera kuzinthu zachilengedwe.
Ntchito: Retarder imatha kuchepetsa nthawi yoyika matope, kuwonjezera nthawi yogwira ntchito ndikulimbikitsa njira yosinthira.
6. Kudzaza:
Gwero: Zodzaza zimatha kukhala zachilengedwe (monga miyala yamchere) kapena zopangidwa.
Ntchito: Zodzaza zimathandizira kuchuluka kwa matope, kukulitsa kuchuluka kwake komanso kukhudza zinthu monga kachulukidwe ndi matenthedwe amafuta.
7. CHIKWANGWANI:
Gwero: Ulusi ukhoza kukhala wachilengedwe (monga ulusi wa cellulose) kapena wopangidwa (monga ulusi wa polypropylene).
Ntchito: Ulusiwu umapangitsa kuti matope azikhala olimba komanso osinthasintha komanso amachepetsa chiopsezo chosweka.
8. Madzi:
Gwero: Madzi azikhala aukhondo komanso oyenera kumwa.
Ntchito: Madzi ndi ofunikira pakupanga hydration ya pulasitala ndi zosakaniza zina, zomwe zimathandizira kukulitsa mphamvu yamatope.
Ndondomeko Yopanga:
Kukonzekera zopangira:
Gypsum amakumbidwa ndikukonzedwa kuti apeze ufa wabwino.
Zophatikizazo zimasonkhanitsidwa ndikuphwanyidwa mpaka kukula kofunikira.
Ma cellulose ethers amapangidwa kuchokera ku cellulose magwero kudzera mukupanga mankhwala.
kusakaniza:
Gypsum, aggregate, cellulose ethers, superplasticizer, retarder, fillers, fibers ndi madzi amayezedwa ndendende ndikusakanikirana kuti apeze chisakanizo chofanana.
QC:
Kuphatikizikako kumayesedwa mozama kwambiri kuti zitsimikizire kuti zikukwaniritsa kusasinthika, mphamvu ndi zina zogwirira ntchito.
Phukusi:
Chomalizacho chimapakidwa m'matumba kapena m'mitsuko ina kuti igawidwe ndikugwiritsidwa ntchito kumalo omanga.
Pomaliza:
Kupanga matope odziyimira pawokha opangidwa ndi gypsum kumafuna kusankha mosamala komanso kuphatikiza kwazinthu zopangira kuti mukwaniritse zofunikira. Ma cellulose ethers amagwira ntchito yofunika kwambiri ngati zowonjezera zomwe zimapangitsa kuti matope azitha kugwira ntchito, kumamatira komanso magwiridwe antchito onse. Pamene ntchito yomanga ikupitabe patsogolo, kafukufuku ndi chitukuko cha sayansi yazinthu zitha kupititsa patsogolo matope odziyimira pawokha, kuphatikiza kugwiritsa ntchito zowonjezera komanso zopangira zokhazikika.
