Viscosity ya cellulose ether HPMC pamadzi odziyimira pawokha

Kukhuthala kwa Hydroxypropyl Methylcellulose (HPMC) komwe kumagwiritsidwa ntchito popanga matope odziyimira pawokha ndi gawo lofunikira kwambiri lomwe limakhudza kayendedwe, magwiridwe antchito, ndi magwiridwe antchito a matope. Madontho odziyendetsa okha amapangidwa kuti aziyenda mosavuta ndikudzikweza okha popanda kugwedezeka, kupangitsa kuwongolera kwa mamachulukidwe kofunikira kuti mukwaniritse zomwe mukufuna. Nayi chitsogozo chambiri pakusankha kukhuthala kwa HPMC pamatope odziyimira pawokha:

1. Makanema Otsika Makalasi: Zodzikongoletsera zokha zimafunikira HPMC yokhala ndi mamasukidwe otsika a 400 CPS. Magiredi awa a HPMC amapereka mawonekedwe ofunikira ndikuwongolera kumatope ndikusungabe mgwirizano komanso bata.
2. Specific Viscosity Range: Kukhuthala kwapadera kwa HPMC komwe kumagwiritsidwa ntchito popanga matope odziyimira pawokha kumatha kusiyanasiyana kutengera zinthu monga kuyenda komwe kumafunidwa, makulidwe a ntchito, kutentha kozungulira, ndi nthawi yochiritsa. Komabe, mamasukidwe akayendedwe amtundu wa 400 mPa·s amagwiritsidwa ntchito popanga matope odzipangira okha.
3. Kugwira Ntchito ndi Kuwongolera Kuyenda: Kukhuthala kwa HPMC kuyenera kusinthidwa kuti kukwaniritsidwe kofunikira komanso kuyendetsa bwino kwa matope odziyendetsa okha. Magiredi otsika a viscosity amapereka kuyenda kwakukulu komanso kufalikira kosavuta, pomwe magiredi apamwamba a viscosity amapereka kuwongolera kwakuyenda bwino komanso kusanja katundu.
4. Kugwirizana ndi Zowonjezera Zina: HPMC yogwiritsidwa ntchito popanga matope odziyimira pawokha iyenera kukhala yogwirizana ndi zowonjezera zina monga superplasticizers, air intrainers, ndi defoamers. The mamasukidwe akayendedwe a HPMC ayenera kusankhidwa kuonetsetsa kuti n'zogwirizana ndi zowonjezera izi ndi kusunga ankafuna katundu matope.
5. Kuwongolera Ubwino ndi Kuyesa: Ndikofunikira kuyesa mosamalitsa kuwongolera khalidwe kuti mudziwe kukhuthala koyenera kwa HPMC pakupanga matope odziyimira pawokha. Kuyesa kungaphatikizepo kuyeza kwa ma rheological, kuyezetsa mayendedwe, ndi kuwunika magwiridwe antchito pansi pamikhalidwe yoyeserera.
6. Malingaliro Opanga: Opanga a HPMC nthawi zambiri amapereka zidziwitso zaukadaulo ndi malangizo omwe amawonetsa magiredi ovomerezeka a viscosity pamapulogalamu osiyanasiyana, kuphatikiza matope odzipangira okha. Ndikoyenera kuwona malingalirowa ndikugwira ntchito limodzi ndi othandizira a HPMC kuti musankhe kalasi yoyenera kwambiri ya viscosity pakugwiritsa ntchito kwanuko.

Mwachidule, kukhuthala kwa HPMC kwa matope odziyimira pawokha kuyenera kusankhidwa mosamala potengera momwe amafunira, kugwirira ntchito, komanso zofunikira za matope, poganizira zinthu monga makulidwe a ntchito, mikhalidwe yozungulira, kuyanjana ndi zowonjezera zina, ndi wopanga. malingaliro.
