HPMC (hydroxypropyl methylcellulose) ndizowonjezera zomwe zimagwiritsidwa ntchito kwambiri mu putty powder. Amagwiritsidwa ntchito ngati thickener, stabilizer ndi binder. Komabe, pakhala pali nkhawa kuti HPMC ikhoza kukhala ndi zotsatira zoipa pa ubwino wa putty powder.
Vuto 1: Kusamamatira bwino
Imodzi mwa mavuto akuluakulu omwe angabwere pamene HPMC imagwiritsidwa ntchito ndi putty powder ndi kusamata bwino. Izi zingayambitse ming'alu ndi zina zowonongeka. Izi ndichifukwa choti HPMC imachepetsa mphamvu yolumikizana ndi ufa wa putty, zomwe zimapangitsa kuti zikhale zovuta kumamatira pamwamba.
Yankho: Onjezani kuchuluka kwa zowonjezera zina
Kuti athetse vutoli, ndikofunika kuonjezera kuchuluka kwa zowonjezera zina zomwe zingapangitse kumamatira. Zosankha zina zodziwika ndi monga cellulose fiber, calcium carbonate, ndi talc. Powonjezera kuchuluka kwa zowonjezerazi, kuphatikiza kwathunthu kwa ufa wa putty kumatha kuwongolera, ndikupangitsa kuti ikhale yogwira mtima pakukonzanso ndi kudzaza ming'alu ndi kuwonongeka kwina.
Vuto 2: Kuchepa kwa pulasitiki
Vuto lina lomwe lingachitike ndi HPMC mu putty powder ndiloti likhoza kuchepetsa pulasitiki ya osakaniza. Izi zikutanthauza kuti ufa wa putty sudzafalikira mosavuta momwe uyenera kukhalira, ndipo zidzakhala zovuta kwambiri kuti zitheke bwino, ngakhale pamwamba.
Yankho: Gwiritsani ntchito mtundu wina wa HPMC
Njira imodzi yothetsera vutoli ndi kugwiritsa ntchito mtundu wina wa HPMC womwe umapangidwa kuti ukhale wapulasitiki wambiri. Pali mitundu yambiri yosiyanasiyana ya HPMC, ina yomwe imapangidwa mwapadera kuti igwiritsidwe ntchito ndi putty powder. Pogwiritsa ntchito imodzi mwazinthuzi, mukhoza kuonetsetsa kuti ufa wa putty uli ndi pulasitiki yoyenera, zomwe zimapangitsa kuti zikhale zosavuta kuziyika ndikukwaniritsa zomwe mukufuna.
Vuto 3: Kuchedwa kuchiza
Vuto lachitatu ndi HPMC mu ufa wa putty ndikuti limachedwetsa nthawi ya machiritso osakaniza. Izi zikutanthauza kuti ufa wa putty umatenga nthawi yayitali kuti uume ndi kukhazikitsa, zomwe zingakhale zokhumudwitsa kwa ogwiritsa ntchito omwe akufunika kuti ntchitoyi ichitike mwachangu.
Yankho: Sinthani mlingo wa HPMC
Kuti athetse vutoli, kuchuluka kwa HPMC mu osakaniza akhoza kusintha. Poyang'anira mosamala kuchuluka kwa HPMC, nthawi yochiritsa ya putty powder ikhoza kukonzedwa bwino, kuonetsetsa kuti imauma mofulumira popanda kuchedwa. Izi zingafunike kuyesa kwina kosiyanasiyana, koma mwa kupeza malire oyenera, vutoli likhoza kuthetsedwa bwino.
HPMC ndi yowonjezera yowonjezera yomwe imapangitsa kuti ufa wa putty ukhale wabwino. Komabe, pali zovuta zina zomwe muyenera kuzidziwa, makamaka zokhudzana ndi kumamatira, pulasitiki komanso nthawi yochiza. Pomvetsetsa nkhanizi ndikukhazikitsa njira zoyenera, ndizotheka kupanga ufa wapamwamba wa putty womwe umakwaniritsa zosowa za ogwiritsa ntchito. Potengera zovuta izi, titha kuwonetsetsa kuti HPMC ikupitilizabe kukhala chida chofunikira pantchito yomanga.
