Kusiyana pakati peHydroxypropyl Starch ether neHydroxypropyl Methylcellulose mukuvaka

Hydroxypropyl Starch Ether (HPSE) uyeHydroxypropyl Methylcellulose (HPMC)imhando mbiri dzemapolymer anonyungudika mumvura anowanzo shandiswa muindasitiri yekuvaka. Kunyange zvazvo akafanana, pane musiyano mukuru mukugadzirwa kwawo kwemakemikari uye hunhu hwekushanda kwawo. Pazasi pane musiyano mukuru uripo pakati peHydroxypropyl Starch Ether neHydroxypropyl Methylcellulose mukushandiswa kwekuvaka:

1. Maumbirwo emakemikari:

• HPSE (Hydroxypropyl Starch Ether):
  • Inotorwa kubva kustarch, inova makabhohaidhiretsi anowanikwa kubva mumiti yakasiyana-siyana.
  • Yakagadziriswa kuburikidza nehydroxypropylation kuti iwedzere hunhu hwayo.
• HPMC (Hydroxypropyl Methylcellulose):
  • Inotorwa kubva ku cellulose, polymer yechisikigo inowanikwa mumadziro esero emiti.
  • Yakagadziridzwa kuburikidza nehydroxypropylation uye methylation kuti iwane hunhu hwaidiwa.

2. Mashoko Anobva:

• HPSE:
  • Inowanikwa kubva muzvirimwa zvinodyarwa starch, zvakaita sechibage, mbatatisi, kana tapioca.
• HPMC:
  • Zvinobva muzvinhu zvinobva mumiti zvakaita se cellulose, kazhinji kacho zvinosanganisira huni kana donje.

3. Kunyungudika:

• HPSE:
  • Kazhinji inonyunguduka zvakanaka mumvura, zvichiita kuti zvive nyore kupararira mumvura.
• HPMC:
  • Inonyungudika zvikuru mumvura, ichigadzira mhinduro dzakajeka mumvura.

4. Kupisa Kunodziya:

• HPSE:
  • Mamwe maether ehydroxypropyl starch anogona kuratidza hunhu hwekupisa, uko viscosity yemushonga inowedzera nekupisa.
• HPMC:
  • Kazhinji hairatidzi kupisa kwemafuta, uye viscosity yayo inoramba yakagadzikana mukati mekupisa kwakasiyana-siyana.

5. Hunhu hwekugadzira mafirimu:

• HPSE:
  • Inogona kugadzira mafirimu ane kuchinjika kwakanaka uye hunhu hwekunamatira.
• HPMC:
  • Inoratidza hunhu hwekugadzira mafirimu, zvichibatsira mukuvandudza kunamira uye kubatana mukugadzirwa kwezvivakwa.

6. Basa mukuvaka:

• HPSE:
  • Inoshandiswa mukuvaka nekuda kwekukora kwayo, kuchengetedza mvura, uye hunhu hwayo hwekunamira. Inogona kushandiswa muzvigadzirwa zvegypsum, mortars, uye glues.
• HPMC:
  • Inoshandiswa zvakanyanya mukuvaka nekuda kwebasa rayo sechinosimbisa, chinochengetedza mvura, uye chinosimudzira kushanda. Inowanzo kuwanikwa mumamortar akagadzirwa nesimende, manamati emataira, magrout, nedzimwe nzira.

7. Kuenderana:

• HPSE:
  • Inoenderana nezvimwe zvinhu zvekuvaka zvakasiyana-siyana.
• HPMC:
  • Inoratidza kubatana kwakanaka nezvinhu zvakasiyana-siyana zvekuvaka uye zvekuwedzera.

8. Nguva Yekugadzirisa:

• HPSE:
  • Zvinogona kukanganisa nguva yekugadzirwa kwemamwe magadzirirwo ekuvaka.
• HPMC:
  • Zvinogona kukanganisa nguva yekuiswa kwedhaka nezvimwe zvigadzirwa zvinosimbisa simende.

9. Kuchinjika:

• HPSE:
  • Mafirimu anogadzirwa ne hydroxypropyl starch ethers anowanzo chinjika.
• HPMC:
  • Inobatsira pakuchinjika uye kuramba kutsemuka mumafomura ekuvaka.

10. Nzvimbo dzeKushandisa:

• HPSE:
  • Inowanikwa muzvigadzirwa zvakasiyana-siyana zvekuvaka, zvinosanganisira plaster, putty, uye namira.
• HPMC:
  • Inoshandiswa zvakanyanya mumadhaka akagadzirwa nesimende, manamatiro emataira, magrout, nezvimwe zvinhu zvekuvaka.

Muchidimbu, nepo Hydroxypropyl Starch Ether (HPSE) neHydroxypropyl Methylcellulose (HPMC) zvichishanda zvakafanana mukuvaka, mavambo azvo akasiyana emakemikari, hunhu hwekunyungudika, nezvimwe zvinhu zvinoita kuti zvikodzere mafomu akasiyana uye mashandisirwo mukati meindasitiri yekuvaka. Sarudzo pakati pazvo inoenderana nezvinodiwa zvechinhu chekuvaka uye hunhu hwekushanda hunodiwa.
