MHEC, kapena methylhydroxyethylcellulose, ndi chowonjezera chofunikira cha mankhwala chomwe chimagwiritsidwa ntchito kwambiri popanga zinthu zomangira. Makamaka pakuphimba ndi zinthu zomalizitsa monga putty ndi plaster, ntchito ya MHEC ndi yofunika kwambiri.
1. Kuchita kwa MHEC mu putty
Putty ndi chinthu chomwe chimagwiritsidwa ntchito kudzaza makoma osafanana kapena malo ena. Chimafunika kukhala ndi magwiridwe antchito abwino, mphamvu komanso kulimba. Kugwiritsa ntchito MHEC mu putty kumaphatikizapo zinthu izi:
a. Kukhuthala kwa mphamvu
MHEC imatha kuonjezera kwambiri kukhuthala kwa putty ndikuwonjezera kusinthasintha kwake komanso magwiridwe antchito ake. Kukhuthala kumeneku kungathandize kulamulira kukhazikika kwa putty, ndikupangitsa kuti ikhale yosavuta kugwiritsa ntchito ndikusunga makulidwe abwino pamalo oyima popanda kugwa. Kukhuthala koyenera kungathandizenso kuti putty isagwe, zomwe zimapangitsa kuti kapangidwe kake kakhale kosavuta.
b. Kusunga madzi
MHEC imasunga bwino madzi, zomwe ndizofunikira kwambiri pakugwira ntchito kwa putty. Putty imatenga nthawi kuti iume ndikulimba ikagwiritsidwa ntchito. Ngati chinyezi chatayika mwachangu, chimapangitsa kuti pamwamba pa putty pasweke kapena kukhala ufa. MHEC imatha kupanga filimu yosunga madzi mu putty ndikuchepetsa kuchuluka kwa madzi omwe amatuluka, motero kuonetsetsa kuti putty imauma mofanana, kuchepetsa kupangika kwa ming'alu, ndikukweza mtundu wa chinthu chomalizidwa.
c. Limbikitsani kumatirira
MHEC imatha kukonza kumatirira kwa putty, zomwe zimapangitsa kuti ikhale yomatirira kwambiri pazigawo zosiyanasiyana. Izi ndizofunikira kwambiri kuti putty isagwe komanso ikhale yolimba. Kumatirira bwino sikungangoletsa putty kugwa, komanso kumawonjezera kukana kwa putty ndikuwonjezera nthawi yake yogwira ntchito.
2. Kugwira ntchito kwa MHEC mu gypsum
Gypsum ndi zipangizo zomangira zomwe zimagwiritsidwa ntchito kwambiri zomwe zimakhala ndi mphamvu zoteteza moto komanso zokongoletsera. Ntchito ya MHEC mu gypsum siinganyalanyazidwe. Makhalidwe ake akuluakulu ndi awa:
a. Kuwongolera magwiridwe antchito a ntchito
MHEC imawongolera luso la pulasitala pokonza zinthu, zomwe zimapangitsa kuti zikhale zosavuta kusakaniza ndi kufalitsa. Mwa kusintha kukhuthala ndi kusinthasintha kwa gypsum slurry, MHEC ingathandize ogwira ntchito yomanga kuti azilamulira bwino kuchuluka ndi makulidwe a gypsum yomwe imagwiritsidwa ntchito. Izi ndizothandiza kwambiri pakukweza magwiridwe antchito omanga komanso kusalala kwa chinthu chomalizidwa.
b. Kulimbitsa kukana ming'alu
Pulasitala imatha kusweka mosavuta panthawi yolimba, zomwe zingakhudze mawonekedwe ake ndi magwiridwe ake. Kugwira ntchito kwa MHEC kusunga madzi kumatha kuchepetsa kuchuluka kwa madzi mu gypsum, kuchepetsa kupsinjika kwamkati, potero kuchepetsa kuchuluka kwa ming'alu. Kuphatikiza apo, MHEC imatha kusintha kusinthasintha kwa pulasitala, ndikupangitsa kuti ikhale yolimba kupsinjika kwakunja.
c. Konzani kuti pamwamba pakhale posalala
Kugwiritsa ntchito MHEC mu gypsum kungathandizenso kuti pamwamba pake pakhale posalala komanso kupangitsa kuti zinthu zopangidwa ndi gypsum ziwoneke bwino kwambiri. Malo osalala samangokongoletsa bwino, komanso amapereka maziko abwino omatirira utoto, zomwe zimathandiza kuti utoto ukhale wosalala pambuyo pake.
Monga chowonjezera chofunikira cha zinthu zomangira, MHEC imasonyeza makhalidwe abwino kwambiri ikagwiritsidwa ntchito mu putty ndi gypsum. Sikuti imangowonjezera magwiridwe antchito omanga, kukonza kumatira ndi kusunga madzi a zinthu, komanso imawonjezera kwambiri kukana ming'alu ndi khalidwe la pamwamba pa chinthu chomalizidwa. Makhalidwe amenewa apangitsa MHEC kugwiritsidwa ntchito kwambiri mumakampani omanga, kukhala gawo lofunikira la zipangizo monga putty ndi plaster. Mtsogolomu, ndi chitukuko cha ukadaulo womanga ndi kusintha kwa zofunikira pakugwira ntchito kwa zinthu, mwayi wogwiritsa ntchito MHEC udzakhala wokulirapo.
