Mafunso 4 okhudza HPMC

1. Kodi hydroxypropyl methylcellulose (HPMC) amagwiritsidwa ntchito bwanji?
HPMC chimagwiritsidwa ntchito zomangamanga, zokutira, utomoni kupanga, zoumba, mankhwala, chakudya, nsalu, ulimi, zodzoladzola, fodya ndi mafakitale ena.HPMC akhoza kugawidwa mu kalasi yomanga, kalasi chakudya ndi mankhwala kalasi malinga ndi ntchito yake.Pakadali pano, zopanga zambiri zaku China zili pamlingo womanga.Pakumanga, ufa wa putty umagwiritsidwa ntchito mochulukira, pafupifupi 90% ngati ufa wa putty ndi winawo ngati matope a simenti ndi zomatira matailosi.

2. Kodi zomwe zimayambitsa matuza mu putty powder ndi chiyani pakugwiritsa ntchito HPMC mu putty powder?
HPMC imagwira ntchito ngati thickener, chosungira madzi ndi kumanga mu putty powders.Sizikhudzidwa ndi zomwe zimachitika.

Zomwe zimayambitsa matuza: 1. Madzi ambiri.2. Chigawo chapansi sichiri chouma, ingochotsani chingwe pamwamba pake, chomwe chimakhalanso mosavuta.

3. Kodi pali mitundu ingati ya hydroxypropyl methylcellulose (HPMC)?Kodi pali kusiyana kotani pakati pawo?
HPMC akhoza kugawidwa mu yomweyo ndi otentha sungunuka.Nthawi yomweyo sungunuka mankhwala, dissipate mwamsanga ndi kutha m'madzi m'madzi ozizira.Panthawiyi, madziwa alibe mamasukidwe akayendedwe monga HPMC amangomwazika m'madzi ndipo samasungunuka.Pambuyo pa mphindi ziwiri, kukhuthala kwamadzimadzi kumawonjezeka pang'onopang'ono, ndikupanga gel osakaniza bwino.Zotentha zosungunuka zimatha kumwazikana mwachangu m'madzi otentha ndikuzimiririka m'madzi otentha.Pamene kutentha kumatsikira ku kutentha kwina, kukhuthala kumawonekera pang'onopang'ono mpaka gel owoneka bwino amapangidwa.

Mtundu wotentha wosungunuka ukhoza kugwiritsidwa ntchito mu ufa wa putty ndi matope.Mu zomatira zamadzimadzi ndi utoto, makeke amapezeka ndipo sangathe kugwiritsidwa ntchito.Mtundu wapomwepo umakhala ndi ntchito zambiri ndipo ukhoza kugwiritsidwa ntchito mu ufa wa putty ndi matope komanso zomatira zamadzimadzi ndi utoto.

4. Kodi mtundu wa hydroxypropyl methylcellulose (HPMC) ungadziwike bwanji mosavuta komanso mowonekera?
(1) Kukoka kwapadera: Kukwera kwa mphamvu yokoka kumapangitsa kuti khalidweli likhale labwino.
(2) Kuyera: Zinthu zambiri zabwino zimakhala zoyera bwino.Kupatula omwe ali ndi zowonjezera zoyera.Whitening agents zingakhudze khalidwe.
(3) Ubwino: Kukongoletsedwa kwabwinoko, kumapangitsanso kukhala kwabwino.Kukongola kwa HPMC yathu nthawi zambiri kumakhala mauna 80 ndi mauna 100, mauna 120 amapezekanso.
(4) Transmittance: Ikani HPMC m'madzi kuti mupange gel owoneka bwino ndikuwona kufalikira kwake.Kuchuluka kwa transmittance, zinthu zosasungunuka zimachepa.Ma riyakitala osunthika nthawi zambiri amakhala ndi ma transmittance abwinoko ndipo zopingasa zopingasa sizimadutsa bwino, koma izi sizitanthauza kuti kupanga kwa ma riyakitala ofukula ndikwabwino kuposa njira zina zopangira.Pali zinthu zambiri zomwe zimatsimikizira ubwino wa mankhwalawa muzitsulo zopingasa, zomwe zimakhala ndi hydroxypropyl yambiri komanso hydroxypropyl yambiri, yomwe ili yabwino kwambiri yosungira madzi.
