Isibonelo se-Cellulose erher

Isibonelo se-Cellulose err yi-polymer compound eyenziwe nge-cellulose ngesakhiwo se-ether. Indandatho ngayinye ye-glucose e-cellulose macromolecule inamaqembu amathathu e-hydroxyl, iqembu eliyinhloko le-hydroxyl eqenjini lesithupha sekhabhoni, neqembu lesibili le-hydroxyl ku-athomu yekhabhoni yesibili neyesithathu. I-hydrogen eqenjini le-hydroxyl ithathelwa indawo yi-hydrocarbon group ukwakha iselula. Kungumkhiqizo wokufakwa esikhundleni se-hydroxyl hydrogen ngeHydrocarbon Group eCellulose Polymer. I-Cellulose yi-polyhydroxy polymer compound engancibilika futhi ayincibilike. I-cellulose ingachithwa emanzini, i-dilite solution kanye ne-organic solvent ngemuva kokuthethelwa, futhi inezakhiwo ze-thermoplastic.

I-Celsulose Ether yisikhathi esijwayelekile sochungechunge lwemikhiqizo ekhiqizwa ukusabela kwe-Alkali Cellulose kanye ne-ejenti ethembisa ngaphansi kwezimo ezithile. I-Alkali Cellulose ifakwa esikhundleni ngama-ejenti ahlukile aphelelisa ukuthola izipho ze-cellulose ezihlukile.

Ngokwezakhiwo ze-Ionization zokufakaza kwabanye, i-Celsulose Tersor Isibonelo zingahlukaniswa nge-Ionic (njenge-carboxymethyl cellulose) ne-nonic (njenge-methyl cellulose) izigaba ezimbili.

Ngokusho kohlobo lwe-subspeent, i-cellulose testers eyisibonelo ingahlukaniswa nge-ether eyodwa (efana ne-methyl cellulose) ne-ether exubile (efana ne-hydroxypropyll methyl celtule). Ngokusho kwe-solubity, ingahlukaniswa inyumbazane yamanzi (efana ne-hydroxyethyl cellulose) kanye ne-organic solvent allobulity (njenge-ethyl cellulose). Udaka oluhlanganisiwe olomile ikakhulukazi lusebenzisa i-cellulose engenamanzi, engahlukaniswa ngohlobo olususwayo olususwayo futhi libambezele uhlobo lokuncibilika ngemuva kokwelashwa komhlaba.

Ama-Admixtures adlala indima ebalulekile ekwenzeni ngcono izakhiwo zodaka oluxutshwe kanye ne-akhawunti ngaphezulu kwezindleko zezinto ezibonakalayo ku-st ngodaka oluhlanganisiwe. Ingxenye enkulu yokuhlanganiswa emakethe yasekhaya ihlinzekwa ngabakhiqizi bakwamanye amazwe, kanye nemithamo yezethenjwa yomkhiqizo nayo ihlinzekwa ngabahlinzeki. Ngenxa yalokhu, izindleko zemikhiqizo yodaka eyomile ehlanganisiwe ihlala iphakeme, futhi kunzima ukuwadumisa udaka olujwayelekile lwe-masonry kanye nodaka olubukhali ngenani elikhulu nendawo ebanzi. Imikhiqizo yemakethe ephelele ilawulwa yizinkampani zakwamanye amazwe, abakhiqizi bomuntu obomile abakhiqizi abaphansi, imali ekhokhwayo engeyinhle; Ukusetshenziswa kwe-admixture akunakuhleleka nocwaningo oluhlosiwe kanye nokwenziwa okubhekiswe kuzo, landela ngokungaboni

I-ejenti yokugcinwa kwamanzi ingukuhlanganiswa okuyisisekelo ukuthuthukisa ukusebenza kokugcinwa kwamanzi kodaka oluhlanganisiwe olomile kanye nelinye lama-admixtures asemqoka ukunquma izindleko zodaka zomuntu omile. Umsebenzi oyinhloko we-cellulose ether ukugcina amanzi.

Indlela yokwenza isenzo se-cellulose ether ngodaka kunje:
