Air-entraining mhedzisiro ye cellulose ether

Cellulose ethers, kusanganisira methyl cellulose (MC), hydroxypropyl methylcellulose (HPMC), uye mamwe, anogona kuratidza mhepo-entraining mhedzisiro mukongiri kana yakanyatsogadzirwa. Heano mabatiro anoita cellulose ethers kumhepo-inopinza maitiro mukongiri:

1. Kudzikamiswa kweMhepo Bubbles:

• Cellulose ethers inoshanda sezvitsigiso zvemabhuru emhepo anounzwa mumusanganiswa wekongiri. Aya mabhuru emhepo anowanzo kugadzirwa kuburikidza nekuita kwemuchina wekusanganisa kana nekuwedzera kwemhepo-inopinza vamiririri.

2. Chiitiko chepamusoro:

• Cellulose ethers ine surfactant properties, iyo inovabvumira kuderedza kushushikana kwepamusoro pamhepo-mvura interface. Izvi zvinobatsira kudzikamisa mabhubhu emhepo uye kudzivirira kubva pakubatana kana kudonha panguva yekusanganiswa, kuiswa, nekurapa.

3. Kupararira kwakavandudzwa:

• Cellulose ethers inosimudzira kupararira kwemabhuru emhepo mukati mekongiri matrix. Izvi zvinoguma nekupararira kwakafanana kwemhepo yemhepo, iyo inobatsira kune inodiwa zvimiro zvekongiri yemhepo, sekuwedzera kusimba, kutonhora-kunyungudika kuramba, uye kushanda.

4. Kuchengeta Mvura:

• Cellulose ethers inovandudza maitiro ekuchengetedza mvura emusanganiswa wekongiri, zvichiita kuti zvive nani kutonga kwemhepo-entraining process. Nekuchengetedza unyoro mukati mekrete, cellulose ethers inobatsira kuchengetedza kugadzikana kwemhepo isina chinhu uye kudzivirira kurasikirwa kwakanyanya kwemhepo panguva yekusanganiswa uye kuiswa.

5. Kugadziridza Rheology:

• Cellulose ethers inogona kugadzirisa rheological maitiro ekongiri musanganiswa, inokanganisa kuyerera kwavo uye kushanda. Izvi zvinogona kupesvedzera nenzira isina kunanga nzira yekupinza mhepo nekugadzirisa mamiriro ekuumbwa uye kudzikamiswa kwemhepo inoputika.

6. Kuenderana nemamwe maAdmixtures:

• Cellulose ethers inopindirana neyakasiyana-siyana yezvimwe zvakasanganiswa zvinowanzoshandiswa mumisanganiswa yekongiri, kusanganisira air-entraining agents, plasticizers, uye superplasticizers. Uku kuwirirana kunobvumira kugadzirwa kwekongiri musanganiswa neakagadzirirwa zvimiro uye maitiro ekuita.

7. Inodzorwa Entrapped Air Content:

• Nekugadzirisa chiyero uye rudzi rwe cellulose ether inoshandiswa, vagadziri vekongiri vanogona kudzora huwandu uye kugoverwa kwemweya wakapinzwa muchigadzirwa chekupedzisira. Izvi zvinovagonesa kusangana nezvinodiwa zvemukati zvemhepo, kushanda, uye kusimba mumashandisirwo akasiyana.

Muchidimbu, cellulose ethers inoita basa rakakosha mukuita kwemhepo-kupinza mukongiri nekudzikamisa mabhuru emhepo, kuvandudza kupararira, kuwedzera kuchengetwa kwemvura, kugadzirisa rheology, uye kuve nechokwadi chekuenderana nezvimwe zvinosanganiswa. Izvi zvinoita kuti pave nekugadzirwa kwekongiri inopinzwa nemhepo ine simba rakawedzerwa, kuomesa nechando, uye kushanda nesimba, zvichiita kuti ive yakakodzera kune zvakasiyana-siyana zvekuvaka.
