Misiyano pakati pehydroxyprupyl strar ether uye hydroxypruppropyl methylcellose mukuvaka

Hydroxypruppropyl starch ether (hpse) uyeHydroxyprupyl methylcellose (HPMC)Marudzi ese ari maviri emapuranga anodzvinyirira emvura aigamuchira mune yekuvaka indasitiri. Nepo vachigovana zvakafanana, pane misiyano yakakosha mumakemikari mavo emakemikari uye maitiro ekuita. Pazasi ndidzo misiyano huru pakati pehydroxypropyl Starch Ether uye hydroxypruppropyl methylcellose mune zvekuvaka application:

1. Chemical chimiro:

• Hpse (hydroxypruppropyl starch enther):
  • Inotorwa kubva kumarara, iyo iri carbohydrate yakawanikwa kubva kune dzakasiyana siyana zvirimwa.
  • Yakashandurwa kuburikidza nehydroxypruslation yekutsamwisa zvivakwa zvaro.
• HPMC (hydroxyprupyl methylcellose):
  • Inotorwa kubva ku cellulose, polymer yakasikwa inowanikwa mumasero emaruva ezvirimwa.
  • Yakashandurwa kuburikidza nehydroxypruslation uye methyclation kuti uwane zvivakwa zvaunoda.

2. Kunobva zvinhu:

• Hpse:
  • Inowanikwa kubva kune zvakadyamadza mashizha emhando, senge chibage, mbatatisi, kana tapioca.
• HpMC:
  • Inotorwa kubva kune inodyara-yakavakirwa cellulose zvinyorwa, kazhinji huni protp kana machira.

3. Solubility:

• Hpse:
  • Kazhinji inoratidzira yakanaka mvura solubility, ichibvumira kuparadzaniswa nyore nyore mumvura-yakavakirwa mvura.
• HpMC:
  • Mvura yakanyanya-nyoro, inogadzira mhinduro dzakajeka mumvura.

4. Thermal Glation:

• Hpse:
  • Mamwe hydroxyprupropropyl starch anaitari anogona kuratidza marongero emhepo emagetsi, uko viscosity yemhinduro inowedzera nekushisa.
• HpMC:
  • Kazhinji hazviratidzi kuratidzira mvura yekuTymal, uye visikopa yaro inoramba yakagadzikana pane huwandu hwe tembiricha.

5. Firimu-kugadzira zvivakwa:

• Hpse:
  • Inogona kuumba mafirimu neakanaka kuchinjika uye kuyemura zvivakwa.
• HpMC:
  • Inoratidza zvivakwa zvefirimu-kugadzira, zvinobatsira kuti uvakidziridze kuderedza uye kubatana muzvivakwa zvekuvaka.

6. Basa mukuvaka:

• Hpse:
  • Inoshandiswa pakuvaka maficha ekuratidzira kwayo, kuchengetwa kwemvura, uye kunamatira zvivakwa. Inogona kunge ichishandiswa muzvigadzirwa zveGypsum-based, motokari, uye anomanoma.
• HpMC:
  • Inoshandiswa zvakanyanya mukuvakwa nebasa rayo seanorira, kumiremba wemvura, uye kushandira enhcuncer. Zvinowanzowanikwa mumutengo wetsiva-bundu, kuomesa, kuchema, uye kumwe kufungidzira.

7. Kuenderana:

• Hpse:
  • Inoenderana nehuwandu hweimwe yekuwedzera yekuvaka uye zvigadzirwa.
• HpMC:
  • Inoratidzira kuwirirana kwakanaka nezvinhu zvakasiyana siyana zvekuvaka uye zvinowedzera.

8. Kuedza nguva:

• Hpse:
  • Inogona kukanganisa nguva yekuisa pane zvimwe zvekuvaka.
• HpMC:
  • Inogona kupesvedzera nguva yekuisa yemutumbi uye zvimwe zvigadzirwa zvekumisikidzwa.

9. Kuchinjika:

• Hpse:
  • Mafirimu akaumbwa nehydroxyprupropyl starch aungana anowanzo shandurwa.
• HpMC:
  • Inopa mukuchinjika uye kupaza kudzikisira muzvivakwa zvekuvaka.

10. Nzvimbo dzekushandisa:

• Hpse:
  • Inowanikwa mune dzakasiyana siyana zvigadzirwa zvekuvaka, kusanganisira plaster, putty, uye zvinonamatira mafomu.
• HpMC:
  • Inowanzo shandiswa mumutero-yakavakirwa motsi, madhimoni anonamira, magirazi, uye zvimwe zvinhu zvekuvaka.

Mukupfupikisa, nepo mese hydroxypressl starch ether (HPse) uye hpmc) zvinoshanda zvinangwa zvakafanana, uye zvimwe zvinhu zvinovaita kuti zviite zvakarongeka kuti zviitwe zvimiro zvakasiyana uye zvinoshandiswa mukati meindasitiri yekuvaka. Iko kusarudzwa pakati pawo kunoenderana nezvinodiwa zvezvinhu zvekuvaka uye hunhu hwaunoda maitiro.
