Kusiyana pakati pa Hydroxypropyl Starch ether ndi Hydroxypropyl Methylcellulose pa Ntchito Yomanga

Hydroxypropyl Starch Ether (HPSE) ndiHydroxypropyl Methylcellulose (HPMC)ndi mitundu yonse ya ma polima osungunuka m'madzi omwe amagwiritsidwa ntchito pomanga.Ngakhale amagawana zofanana, pali kusiyana kwakukulu pamapangidwe awo amankhwala ndi machitidwe awo.M'munsimu pali kusiyana kwakukulu pakati pa Hydroxypropyl Starch Ether ndi Hydroxypropyl Methylcellulose muzomangamanga:

1. Kapangidwe ka Chemical:

• HPSE (Hydroxypropyl Starch Ether):
  • Chochokera ku wowuma, chomwe ndi chakudya chochokera ku zomera zosiyanasiyana.
  • Amasinthidwa kudzera mu hydroxypropylation kuti apititse patsogolo mphamvu zake.
• HPMC (Hydroxypropyl Methylcellulose):
  • Wochokera ku cellulose, polima wachilengedwe wopezeka m'makoma a cell a zomera.
  • Kusinthidwa kudzera mu hydroxypropylation ndi methylation kuti mukwaniritse zomwe mukufuna.

2. Zolemba:

• HPSE:
  • Amatengedwa kuchokera ku zomera zowuma, monga chimanga, mbatata, kapena tapioca.
• HPMC:
  • Zochokera ku zomera zochokera ku cellulose, nthawi zambiri zamkati zamatabwa kapena thonje.

3. Kusungunuka:

• HPSE:
  • Nthawi zambiri amawonetsa kusungunuka kwamadzi bwino, kulola kubalalika kosavuta m'madzi opangira madzi.
• HPMC:
  • Kusungunuka kwambiri m'madzi, kupanga njira zomveka bwino m'madzi.

4. Kutentha kwa Gelation:

• HPSE:
  • Ena hydroxypropyl wowuma etha akhoza kusonyeza matenthedwe gelation katundu, kumene mamasukidwe akayendedwe a yankho kumawonjezeka ndi kutentha.
• HPMC:
  • Nthawi zambiri sawonetsa matenthedwe a gelation, ndipo kukhuthala kwake kumakhalabe kokhazikika pamitundu yosiyanasiyana ya kutentha.

5. Katundu Wopanga Mafilimu:

• HPSE:
  • Itha kupanga mafilimu okhala ndi kusinthasintha kwabwino komanso zomatira.
• HPMC:
  • Imawonetsa mawonekedwe opangira mafilimu, zomwe zimathandizira kuti kumamatira bwino komanso kugwirizanitsa pamapangidwe omanga.

6. Ntchito Yomanga:

• HPSE:
  • Amagwiritsidwa ntchito pomanga ntchito zomangirira, kusunga madzi, ndi zomatira.Itha kugwiritsidwa ntchito pazinthu zopangidwa ndi gypsum, matope, ndi zomatira.
• HPMC:
  • Amagwiritsidwa ntchito kwambiri pomanga chifukwa cha ntchito yake monga thickener, wosungira madzi, komanso chowonjezera ntchito.Nthawi zambiri amapezeka mumatope opangidwa ndi simenti, zomatira matailosi, ma grouts, ndi zina.

7. Kugwirizana:

• HPSE:
  • Yogwirizana ndi zosiyanasiyana zomangira zina ndi zipangizo.
• HPMC:
  • Imawonetsa kuyanjana kwabwino ndi zida zosiyanasiyana zomangira ndi zowonjezera.

8. Kukhazikitsa Nthawi:

• HPSE:
  • Zitha kukhudza nthawi yokhazikitsidwa ya zomanga zina.
• HPMC:
  • Zitha kukhudza nthawi yoyika matope ndi zinthu zina za simenti.

9. Kusinthasintha:

• HPSE:
  • Mafilimu opangidwa ndi hydroxypropyl starch ethers amakhala osinthasintha.
• HPMC:
  • Zimathandizira kusinthasintha komanso kukana ming'alu pakupanga mapangidwe.

10. Malo Ogwiritsira Ntchito:

• HPSE:
  • Amapezeka m'zinthu zosiyanasiyana zomanga, kuphatikizapo pulasitala, putty, ndi zomatira.
• HPMC:
  • Nthawi zambiri amagwiritsidwa ntchito mumatope opangidwa ndi simenti, zomatira matailosi, ma grouts, ndi zida zina zomangira.

Mwachidule, pamene onse a Hydroxypropyl Starch Ether (HPSE) ndi Hydroxypropyl Methylcellulose (HPMC) amagwira ntchito zofanana pomanga, magwero awo apadera a mankhwala, makhalidwe osungunuka, ndi zinthu zina zimawapangitsa kukhala oyenera kupanga zosiyana ndi ntchito mkati mwa mafakitale omanga.Kusankha pakati pawo kumadalira zofunikira zenizeni za zipangizo zomangira ndi makhalidwe omwe akufuna.
