Ndeapi mabasa ekuumbwa kwechikafu chemheremalose ether?

DEscrlbe:

Kuumbwa kwechikafu kunoenderana cellulose ana

TEchnical munda:

Chigadzirwa chazvino chinoenderana nekuumbwa kwechikafu chine cellulose ana vana.

Background maitiro:

Izvo zvave nguva refu kuverengerwa cellpomse manyoro mukuumbwa kwechikafu, kunyanya kugadziriswa kwezvekudya, kugadzirisa zvinhu zvakasiyana-siyana zvakaringana uye / kana kugadzirisa kusimba panguva yekugadzira, Briteni Patent application GB 2 444 020 inoburitsa zvakadai zvekudya zvekudya zvinosanganisira iyo cellulose cellulose, hydroxypruslosel cellulose, kana hydroxypruppropyl methylose. Methylcellose uye hydroxyprupyl methylcellose ane "thermos inodzokera kujekesa zvinhu". Zvinonyatsorondedzera kuti kana mhinduro yekumusoro ye methylceulose kana hydroxyprupyl methylcellose inotyisa, iyo hydrophobic metroxic yeboka iri mumhanyi Kune rimwe divi, apo iyo gel ichikonzerwa, iyo hydrophobic mapoka mapoka anovandudzwa, nepo glet inodzokera kumhinduro yekutanga mhinduro.

European Patent EP i 171 471 inoburitsa methylcellose iyo inobatsira kwazvo mune yakasimba chikafu chekusimbisa, nyama, uye soya padzvo nekuda kwesimba rayo rakawedzera. MetHylcellose inopa yakavandudzwa kusimba uye kubatana kuchimiro chakasimba chekudya, nekudaro zvichipa kuruma kwakanaka kunzwa kune vatengi vachidya mari yekuchinjiswa. Kana ikanyungudika mumvura inotonhora (semuenzaniso, 5 ° C kana kuderera) zvisati zvaitika kana mushure mekunge zvimwe zvidzimwe zvasara zvichisvika zvizere zvekupa chikafu chakasimba uye chakasimba chekusimba uye kusimba kwakanaka uye kubatana. kugona.

Nekudaro, mune zvimwe zviitiko, kushandiswa kwemvura inotonhora hakuna kujairika kuti ugadzire kwechimiro chekudya. Saizvozvo, zvingave zvakafanira kupa cellevalose kurumbidzwa uye kuomesa kwakanaka uye kuomesa kunyange kana iyo cellulose ana yevatya.
