Mokhoa oa ho khetha ether ea cellulose?

Mokhoa oa ho khetha ether ea cellulose?

Ho khetha mofuta o nepahetseng oa cellulose ether ho itšetlehile ka lintlha tse 'maloa, ho kenyelletsa le kopo e khethehileng, litšobotsi tse hlokahalang tsa ts'ebetso, le maemo a ho sebetsa.Mona ke lintlha tse ling tseo u ka li nahanang ha u khetha li-cellulose ethers:

  1. Ho qhibiliha: Li-ether tsa cellulose li na le likhato tse fapaneng tsa ho qhibiliha metsing le lihlapolli tse ling.Ho bohlokoa ho khetha ether ea cellulose e qhibilihang ka har'a sistimi e lakatsehang bakeng sa ts'ebeliso e khethehileng.
  2. Viscosity: The viscosity ea cellulose ethers e ka fapana haholo ho itšetlehile ka tekanyo ea ho nkela sebaka, boima ba molek'hule, le lintlha tse ling.Ho khetha ether ea cellulose e nang le viscosity e loketseng ke ea bohlokoa bakeng sa ho finyella thepa e lakatsehang ea rheological sehlahisoa sa ho qetela.
  3. Lintho tsa ho etsa filimi: Li-ether tse ling tsa cellulose li na le mekhoa e metle ea ho etsa filimi, e ka bang molemo bakeng sa lisebelisoa tse kang lira kapa li-adhesives.
  4. Ho boloka metsi: Li-cellulose ethers li ka ntlafatsa mekhoa ea ho boloka metsi ea metsoako, e leng ea bohlokoa bakeng sa lisebelisoa tse kang li-adhesive tsa lithaele kapa lihlahisoa tse entsoeng ka samente.
  5. Thermal stability: Li-ether tse ling tsa cellulose li na le botsitso bo betere ba mocheso ho feta tse ling, tse bohlokoa bakeng sa lits'ebetso tse hlokang ho pepesehela mocheso o phahameng.
  6. Ho lumellana: Li-cellulose ethers li ka sebelisana le lisebelisoa tse ling ha li etsoa, ​​kahoo ke habohlokoa ho khetha ether ea cellulose e lumellanang le lisebelisoa tse ling.
  7. Litšenyehelo: Litsenyehelo tsa li-cellulose ethers li ka fapana haholo ho itšetlehile ka mofuta le boleng ba thepa, kahoo ke habohlokoa ho khetha ether ea cellulose e fanang ka litšobotsi tse lakatsehang tsa ts'ebetso ka theko e utloahalang.

Qetellong, khetho ea cellulose ether e tla itšetleha ka litlhoko tse khethehileng tsa kopo, 'me e ka kenyelletsa liteko tse ling ho fumana lisebelisoa tse nepahetseng bakeng sa litšobotsi tse lakatsehang tsa tshebetso.
