Hpmc (hydroxypropyl methylcellulose), monga polymer yofunikira ya madzi osungunuka, imagwiritsidwa ntchito kwambiri popanga zida, makamaka m'thumba la khoma la khoma. Sizingakuyenderenso ntchito zomanga, komanso zimapangitsanso kugwiritsa ntchito zotsatira za chinthucho ndikuwonjezera kukhazikika kwa ntchitoyi.
1. Makhalidwe oyambira a HPMC
HPMC ndi ufa wopanda utoto wopanda mafuta wopangidwa kuchokera ku cellulose yosinthidwa mwa mitundu. Ili ndi madzi abwino amadzi ndi zomatira. Kapangidwe kake kamakhala ndi magulu awiri a mankhwala, hydroxypropyl ndi methyl, ndikupatsa mawonekedwe apadera:
Kukula: Pamene HPMC yasungunuka m'madzi, imatha kupanga njira yothetsera ma viscous ndikuwonjezera mawizi opanga zomangamanga ndi zomatira.
Kusungidwa kwamadzi: Kuyika madzi mosamalitsa ndikuletsa madzi kuti asakamize mwachangu, komwe kumathandizanso kupaka utoto ndi kapangidwe ka utoto.
Sinthani magwiridwe antchito: Pangani zopindika ndikumamatira mobwerezabwereza, kuchepetsa mikangano pakumanga, ndikuwongolera ntchito yomanga ogwira ntchito.
Katundu wopanga makanema: Kutha kupanga filimu yofanana kuti ichulukitse zotsatsa.
2. Kugwiritsa ntchito HPMC m'khola
Makoma a Wall ndi chinthu chofunikira pa zomangamanga. Amagwiritsidwa ntchito posankha khoma ndikukonza zofooka za khoma. HPMC imachita mbali yofunika kwambiri monga chowonjezera pamakoma.
Sinthani magwiridwe antchito omanga: Kuwonjezera kuchuluka kwa HPMC yoyenera kutchinga kumatha kusintha magwiridwe antchito a pabwino. Chifukwa cha kukula kwa HPMC, chivundikirocho chimakhala chosalala mukamagwiritsa ntchito, kuchepetsa kukana pomanga ndikuwongolera kusintha kwa ntchito yomanga.
Sinthani zotsatsa: Mphamvu yopanga mafilimu ya HPMC imathandizira kuti pakhome ikhale bwino kwambiri pakhoma, imathandizira chitsamba cha putty, ndipo chimalepheretsa kuthyoka.
Kusunga kwamadzi kopitilira: Kusunga kwamadzi kwa HPMC kumatha kuchedwetsa kuthamanga kwa putty ndikuchepetsa kuchitika kouma. Makamaka mukamapanga malo akuluakulu, zitha kuonetsetsa kuti pulity ndi mkati amawuma nthawi yomweyo kuti mupewe ming'alu yoyambitsidwa ndi kuyanika kwamtunda.
Pewani kukhazikika ndi stratization: Katundu wokulirapo wa HPMC imathanso kuletsa kukhazikitsa ndi stratication to putty nthawi yosungirako komanso kukonza zinthu zosungira.
3. Kugwiritsa ntchito HPMC mu CERAME CILEMENE
Guluu wa TILE siladi yofunikira yomwe imagwiritsidwa ntchito kugwirizanitsa matailosi mpaka pansi pamunsi panjira yochepa. Kugwiritsa ntchito HPMC mu CETRE CRAME CETRE CRART CEROMATOMBO LA BWINO KWAMBIRI chasintha kwambiri ntchito ndi zomanga za simenti.
Sinthani chotsatsa: kuwonjezera kwa HPMC kungalimbikitse kulimbikitsa nyumba ya matauni a matayala, kuwonetsetsa kuti matailosiwo amatsatira pansi ndikuletsa matailosi kuti asachotse. Makamaka pamalo ena osalala kapena osakhazikika, hpmc amatha kukulitsa zitsamba pakati pa guluu ndi maziko.
Sinthani Kugwira Ntchito: KuwonjezeraHpmcTsitsi la mataunga la matayala limatha kusintha kugwiritsidwa ntchito kwa guluu. Nthawi yomanga, gululu la simenti limakhala ndi madzi abwino komanso osavuta kugwira ntchito, kulola ogwira ntchito omanga kuti agwiritse ntchito ndikusintha mawonekedwe a matailosi mosavuta.
Kubwezeretsa madzi kukweza: Madzi osungidwa a HPMC amafunikira makamaka m'masamba a mata matama. Imatha kuchepetsa kuthamanga kwa simenti slorry, kulola guluuzo kuti lisusule bwino kwa nthawi yayitali, kupewa kumanga kosayenera kapena kumasula matailosi oyambitsidwa ndi kuyanika kwambiri.
Sinthani kutsutsana motsutsana: Pa nthawi yowumitsa guluu la simenti, shrinkage kapena ming'alu imakonda kuchitika. Posintha ma Isccect ndi mawonekedwe a filimu a Centa, HPMC mosamalitsa mavuto obwera chifukwa cha simenti amawuma, motero kukonza mawonekedwe onse.
4. Ubwino wina wa HPMC pakumanga
Chitetezo cha chilengedwe: hpmc ndi zinthu zobiriwira komanso zachilengedwe zachilengedwe, osati zoopsa komanso zopanda vuto, ndipo sizingavulaze thupi laumunthu ndi chilengedwe. Chifukwa chake, kugwiritsa ntchito kwake m'makampani omanga kumakumana ndi zinthu zamakono zoteteza zachilengedwe.
Zachuma: HPMC imatha kukwaniritsa zotsatira zazikuluzikulu ndi kugwiritsidwa ntchito kochepa ndipo ili ndi ndalama zambiri. Kuphatikizidwa kwake kumatha kukonza kwambiri gulu la temple ndi matabwa a matanga, pomwe mukuchepetsa ndalama zopangira.
Kusintha Kwamphamvu: HPMC ili ndi kufanana ndi zinthu zina zomangamanga monga simenti, gypsum, latc., ndi zina zosiyanasiyana zitha kusintha momwe zimafunikira kukwaniritsa zofunikira zosiyanasiyana.
Kugwiritsa ntchitoHpmcM'makoma opanga ndi matanga a matanga amalimbikitsa kuti zisapangitse kutengera, zomanga ndi zokhazikika za nkhaniyi, komanso zimalepheretsa ming'alu, kukhazikika ndi mavuto ena. Monga malo achilengedwe, azachuma komanso owonjezera abwino, owonjezera bwino, hpmc amapereka zinthu zabwino kwambiri pakukonzekera ntchito zamakono. Makampani omanga akupitiliza kutetezedwa ndi chilengedwe ndi luso la zomangamanga, kugwiritsa ntchito HPMC kufala kwambiri, ndikugwira ntchito yofunika kwambiri pokonza zinthu zonse zomangira.
