FAQ
Q: Lub luag haujlwm tseem ceeb ntawm PEG4000 hauv roj hmab yog dab tsi?
A: Lub luag haujlwm tseem ceeb yog lubrication thiab demolding, pab hauv dispersion ntawm fillers, txo cov kev sib txhuam, thiab kev txhim kho ntau lawm efficiency thiab roj hmab zoo.
Q: Puas muaj qhov sib txawv piv rau lwm tus qauv PEG (xws li PEG6000)?
A: PEG4000 muaj qhov nruab nrab melting point thiab fluidity zoo dua, ua rau nws tsim nyog rau kev sib xyaw roj hmab thiab kev ua haujlwm. PEG6000 muaj qhov nyuaj dua thiab tsim nyog rau kev siv demolding.
Q: Dab tsi yuav tsum tau sau tseg thaum khaws cia thiab siv nws?
A: Khaws cia rau hauv qhov chaw txias thiab qhuav, kom deb ntawm qhov kub thiab txias, thiab tsis txhob melting thiab caking; ua ntej sib tov, nws tuaj yeem raug crushed ua ntej kom yooj yim dispersion.
