Zomatira za matailosi ndizofunikira kwambiri pakumanga ndi kukonzanso, zomwe zimapereka mgwirizano pakati pa matailosi ndi gawo lapansi. Zomatirazi ziyenera kuwonetsa zinthu zingapo, kuphatikiza kuthekera kogwirira ntchito, kusunga madzi, komanso mphamvu zamamatira. Chimodzi mwazinthu zazikulu zomwe zimakulitsa izi ndi zotumphukira za cellulose. Cellulose, polima yachilengedwe yomwe imapezeka m'makoma a zomera, imasinthidwa ndi mankhwala kuti ipange zinthu zochokera ku methyl cellulose (MC) ndi hydroxypropyl methylcellulose (HPMC), zomwe zimagwiritsidwa ntchito kwambiri pomatira matayala.
Makhalidwe a Ma cellulose Derivatives
Zochokera ku cellulose zomwe zimagwiritsidwa ntchito pomatira matailosi ndi ma polima osungunuka m'madzi omwe amawonetsa mawonekedwe apadera:
Kusunga Madzi: Amatha kusunga madzi ochulukirapo, omwe ndi ofunikira pakuchiritsa kwa zomatira.
Thickening Agent: Amawonjezera kukhuthala kwa zomatira kusakaniza, kuwonetsetsa kugwiritsa ntchito moyenera ndikuchepetsa kuchepa.
Kupanga Mafilimu: Amapanga filimu yopyapyala ikayanika, zomwe zimapangitsa kuti zomata zikhale zolimba komanso kusinthasintha kwa zomatira.
Kusintha kwa Rheology: Amasintha mawonekedwe a zomatira, kuwongolera magwiridwe antchito ake komanso kugwiritsa ntchito mosavuta.
Ntchito za Cellulose mu Tile Adhesive
1. Kusunga madzi
Imodzi mwa ntchito zoyamba za zotumphukira za cellulose mu zomatira matailosi ndikusunga madzi. Panthawi yochiritsa zomatira za simenti, kukhalapo kwa madzi okwanira ndikofunikira pakuchita kwa hydration. Ma cellulose amayamwa ndikusunga madzi, kuwamasula pang'onopang'ono kuti atsimikizire kuti hydration yathunthu. Kutulutsidwa kwamadzi koyendetsedwa kumeneku kumapangitsa mphamvu ndi kulimba kwa chomangira chomata.
Kuchiritsa Kwabwino: Posunga madzi, zotumphukira za cellulose zimalepheretsa kuyanika msanga, zomwe zingayambitse kuchiritsa kosakwanira komanso zomangira zofooka.
Nthawi Yowonjezera Yotsegulira: Zomatira zimakhalabe zogwira ntchito kwa nthawi yayitali, kulola kusintha pakuyika matayala.
2. Kupititsa patsogolo Kugwira Ntchito
Zochokera ku cellulose zimathandizira kugwira ntchito kwa zomatira za matailosi posintha mawonekedwe awo a rheological. Kusakaniza komatira kumakhala kogwirizana komanso kosavuta kufalikira, kuchepetsa khama ndi nthawi panthawi yogwiritsira ntchito.
Kugwiritsa Ntchito Mosalala: Kuchulukitsidwa kwa viscosity kumalepheretsa kugwa ndi kugwa, makamaka pamalo oyimirira.
Kufalikira Kwambiri: Zomatirazo zimafalikira mofanana, kuonetsetsa kuti zatsekedwa kwathunthu ndi kumamatira bwino.
3. Kupititsa patsogolo Kumamatira
Ma cellulose opangidwa ndi cellulose amathandizira kuti agwirizane ndi zomatira za matailosi. Kuthekera kopanga filimu kwa ma polimawa kumatsimikizira mgwirizano wamphamvu pakati pa matailosi ndi gawo lapansi.
Mphamvu ya Bond: Kanema wopyapyala wopangidwa ndi zotumphukira zama cellulose amakulitsa mphamvu yolumikizirana ndi zomatira.
Kusinthasintha: Zomatira zimakhalabe zosinthika, zokhala ndi kayendedwe kakang'ono komanso kuchepetsa chiopsezo cha kutsekedwa kwa matayala.
4. Thickening Agent
Monga thickening agents, zotumphukira za cellulose zimawonjezera kukhuthala kwa zomatira matailosi. Izi ndizofunikira makamaka kuti mukhalebe ogwirizana komanso osasunthika osakaniza zomatira.
Kusasinthika: The unakhuthala zomatira osakaniza amakhala homogenous, kupewa tsankho la zigawo zikuluzikulu.
Kukhazikika: Kukhuthala kochulukira kumachepetsa kuthekera kwa zomatira kuthamanga kapena kudontha, kuzipangitsa kukhala zoyenera pazopingasa komanso zopingasa.
5. Sag Kutsutsa
M'mapulogalamu okhudzana ndi malo oyimirira, monga kuyika matayala pakhoma, kusasunthika ndikofunikira. Zochokera ku cellulose zimathandizira kulimba kwa zomatira zamatayilo, kuwonetsetsa kuti matailosi amakhalabe m'malo mwake komanso pambuyo pake.
Kugwiritsa Ntchito Mowongoka: Chomatiracho chimakhalabe pamalo osatsetsereka, kupereka mphamvu yogwira koyamba ndikuchepetsa kufunikira kwa chithandizo chamakina.
Makulidwe Ofanana: Zomatira zimasunga makulidwe osasinthika, ofunikira kuti akwaniritse matailosi olingana ndi mulingo.
6. Bwino Open Open Time ndi Kusintha
Ma cellulose amawonjezera nthawi yotseguka ya zomatira matailosi, nthawi yomwe matailosi amatha kusinthidwa popanda kusokoneza mphamvu ya mgwirizano. Izi ndizopindulitsa makamaka m'mapulojekiti akuluakulu kumene kuyika bwino ndikofunikira.
Kusintha: Nthawi yotseguka yotalikirapo imalola kuyikanso matailosi kuti awonetsetse kuti akuyenda bwino komanso motalikirana.
Zinyalala Zochepetsedwa: Zomatira sizimayika mwachangu, kuchepetsa zinyalala ndikuwonetsetsa kugwiritsa ntchito bwino zinthu.
Mitundu ya Ma cellulose Omwe Amagwiritsidwa Ntchito Pomatira Tile
Mitundu ingapo ya zotengera za cellulose zimagwiritsidwa ntchito kwambiri pazomatira matailosi, iliyonse ili ndi zabwino zake:
1. Methyl Cellulose (MC)
Kusungunuka kwa Madzi: MC imasungunuka m'madzi, kupanga njira yomveka bwino, yowoneka bwino yomwe imapangitsa kuti madzi asungidwe komanso kugwira ntchito.
Thermal Gelation: MC imawonetsa matenthedwe amafuta, kutanthauza kuti imatenthetsa ikatenthedwa ndikubwerera ku yankho ikazizira, yothandiza kuti zomatira zikhale zokhazikika pakutentha kosiyanasiyana.
2. Hydroxypropyl Methylcellulose (HPMC)
Katundu Wowonjezera: HPMC imapereka kusungika bwino kwa madzi, kumamatira, komanso kupanga mafilimu poyerekeza ndi MC.
Kusinthasintha: Amagwiritsidwa ntchito kwambiri m'mapangidwe osiyanasiyana chifukwa cha kuchuluka kwake kwa makulidwe, kusunga madzi, komanso mawonekedwe ake.
3. Hydroxyethyl Cellulose (HEC)
Kuchulukana Mwachangu: HEC ndi thickener yogwira mtima, yopereka mamasukidwe apamwamba ngakhale pazigawo zochepa.
Kuwongolera kwa Rheological: Imawonjezera kuyenda ndi kusanja kwa zomatira, kuwongolera kugwiritsa ntchito mosavuta.
Zochokera ku cellulose zimagwira ntchito yofunika kwambiri pakugwira ntchito komanso kugwira ntchito kwa zomatira zamatayilo. Kuthekera kwawo kusunga madzi, kupititsa patsogolo magwiridwe antchito, kuwongolera kumamatira, komanso kupereka kukana kwamadzi kumawapangitsa kukhala ofunikira kwambiri pamamangidwe amakono. Kuphatikizika kwa zotuluka pa cellulose monga methyl cellulose, hydroxypropyl methylcellulose, ndi hydroxyethyl cellulose kumawonetsetsa kuti zomatira zamatayilo zimakwaniritsa zofunikira kuti zikhale zolimba, zosavuta kugwiritsa ntchito, komanso kugwira ntchito kwanthawi yayitali. Pamene njira zomangira zikupitilira kusinthika, kufunikira kwa ma polima osunthikawa mu zomatira matailosi kudzakhalabe kofunika, zomwe zikuthandizira kupititsa patsogolo zomangira ndi luso.
