Itandukaniro ryimiterere yumubiri nubumashini no gukoresha HPMC na HEMC mubikorwa byubwubatsi

Hydroxypropyl Methylcellulose (HPMC) na Hydroxyethyl Methylcellulose (HEMC) ni ubwoko bubiri bwa ether ya selile ikoreshwa cyane mubikorwa byubwubatsi. Mugihe basangiye bimwe, hariho kandi itandukaniro ryingenzi mumiterere yumubiri na chimique, kimwe nibisabwa.

Ibyiza bifatika:

1. Gukemura: HPMC na HEMC byombi birashobora gushonga amazi, bivuze ko bishonga byoroshye mumazi kugirango bibe igisubizo kiboneye. Ariko, gukemura kwa HEMC nibyiza kuruta ibya HPMC.
2. Viscosity: Byombi HPMC na HEMC birabyimbye kandi byerekana imyitwarire ya pseudoplastique, bivuze ko ububobere bwabo bugabanuka mugihe bahuye nibibazo byo gukata. HEMC muri rusange ifite ubukonje burenze HPMC.
3. Kubika Amazi: HPMC na HEMC byombi bizwiho gufata neza amazi meza, bigatuma agira akamaro mubikorwa byubwubatsi aho kugenzura ubushuhe ari ngombwa.

Ibikoresho bya shimi:

1. Imiterere yimiti: Itandukaniro nyamukuru hagati ya HPMC na HEMC riri mumiterere yimiti yabo. HPMC ifite hydroxypropyl itsinda ryometse kumugongo wa selile, mugihe HEMC ifite hydroxyethyl itsinda.
2. Imiti ivura imiti: HPMC na HEMC byombi ni ether ya selile ya selile kandi rero ihagaze neza. Nyamara, HEMC ikora cyane kurusha HPMC bitewe nuko hari itsinda rya Ethyl, bigatuma ryandura hydrolysis.

Porogaramu:

1. Porogaramu ya HPMC: HPMC ikunze gukoreshwa mu gufatira amatafari, kuri sima, no ku bicuruzwa bishingiye kuri gypsumu kubera gufata neza amazi hamwe no kubyimba. Irakoreshwa kandi muri sisitemu yo hanze no kurangiza sisitemu (EIFS) kugirango itezimbere imikorere ya minisiteri.
2. Porogaramu ya HEMC: HEMC ikunze gukoreshwa muri minisiteri ishingiye kuri sima, amavuta ya tile, hamwe nibicuruzwa bishingiye kuri gypsumu kubera uburyo bwiza bwo kubika amazi. Irakoreshwa kandi mukuringaniza ibice, aho ikora nkibikorwa byo kugenzura ibintu.

Muri make, HPMC na HEMC ni ubwoko bubiri bwa selile ya selile ikunze gukoreshwa mubikorwa byubwubatsi. Mugihe basangiye bimwe, nkibishobora gukemuka kwamazi, imyitwarire ya pseudoplastique, hamwe nuburyo bwiza bwo gufata amazi, hariho kandi itandukaniro ryingenzi mumiterere yumubiri na chimique, hamwe nibisabwa. HPMC ikunze gukoreshwa mu gufatisha amabati, kuri sima, no ku bicuruzwa bishingiye kuri gypsumu, mu gihe HEMC ikunze gukoreshwa muri minisiteri ishingiye kuri sima, ibyuma bifata amabati, hamwe n’ibikoresho byo kwishyira hamwe.
