Yiziphi izinhlobo ezahlukene ze-cellulose zitholwa ngokhonkolo?

I-Cellulose Ether iyisengezo esibalulekile esakhiweni esisetshenziswa kabanzi ngokhonkolo nodaka ukuze sithuthukise izakhiwo zazo. Imisebenzi esemqoka ye-cellulose ether ngokhonkolo ifaka phakathi ukuqina, ukugcinwa kwamanzi, ukubekezela kokuhlehlisa, ukwenza ngcono ukusebenziseka, njll.

1. I-methyl cellulose (MC, Methylll cellulose)
I-methylcellulose uhlobo oluvame kakhulu lwe-cellulose ether, olukhiqizwa ngokubuyisela amanye amaqembu ama-hydroxyl e-cellulose ngamaqembu we-methoxy (-Och3). I-Methylcellose ikakhulukazi idlala indima yokuqina nokugcinwa kwamanzi ngokhonkolo. Kungathuthukisa kakhulu ukumelana kokhonkolo, ukukhulisa ubumbano lukakhonkolo, ukunciphisa ukopha, ngaleyo ndlela kuthuthukise ukusebenza kokwakha nokuqina kokhonkolo. Ngaphezu kwalokho, i-methylcellulose futhi inezakhiwo ezinhle ezenziwe ngamafilimu, ezingathuthukisa ngempumelelo ubushelelezi nobukhulu bendawo ekhonkolo.

2. I-Hydroxypropylm methyl cellulose (HPMC, Hydroxypropyl Methyl celtule)
I-Hydroxypropylm methylcellulose ikhiqizwa ngokwethula i-hydroxypropyl (-ch2chohchch3) ngesisekelo se-methylcellulose. I-HPMC inokugcinwa kwamanzi okungcono kanye nokuqina kwezindawo, ngakho-ke kukhombisa ukuqina okunamandla kanye nezakhiwo ze-anti-sag ngokhonkolo. Kungagcina ukusebenza okuhle kokugcina amanzi emazingeni okushisa aphezulu futhi kuvikele amanzi ngokhonkolo kusuka ekuhwamukeni ngokushesha, ngaleyo ndlela kunciphise ukwenzeka kwemifantu. Ngaphezu kwalokho, i-HPMC ingaphinde ithathe ijubane lokuphendula kuka-Cement Hydration, okuvumela ukhonkolo ukuze ube nesikhathi esiphelile sokusebenza futhi asebenze.

3. I-Hydroxyyethyl cellulose (I-HEC, HYDROXYETHYL CULLLOSE)
I-Hydroxyyethyl celtulose ikhiqizwa ukwethula amaqembu we-hydroxyethyl (-ch2ch2oh) e-cellulose molecule. Umsebenzi oyinhloko we-HEC ngokhonkolo ukuqina futhi uthuthukise izakhiwo ezibopha ngokhonkolo. Uma kuqhathaniswa nezinye izifebe ze-cellulose, i-HEC igxile ngaphansi kwezimo ze-alkali, ngakho-ke isetshenziswa kabanzi ngokhonkolo. Kungathuthukisa ukusebenza kwe-anti-sag ngokhonkolo futhi kwandise amandla okubopha ukhonkolo. Ikakhulu kukhonkolo oxutshwe kahle odinga ukugcinwa isikhathi eside noma ukuthutha, i-HEC ingavimba ngempumelelo ukunxusa nokopha.

I-4. I-Hydroxypropylllulose (HPC, Hydroxypropyl celtuleose)
I-Hydroxypropylllulose ikhiqizwa ukwethula iqembu le-hydroxypropyl (-ch2chohch3) ku-molecule ye-cellulose. Ifana ne-HPMC, i-HPC nayo inezakhiwo ezinhle zokuqina nokugcinwa kwamanzi. Ngaphezu kwalokho, i-HPC nayo inokuqina okuhle okushisayo kanye nezakhiwo ezenziwe ngamafilimu, ezingathuthukisa ukumelana nokuqhekeka nokuqina kokhonkolo. Ngaphansi kwezimo zokushisa eziphakeme, i-HPC inganciphisa kakhulu ukuhwamuka kwamanzi ngokhonkolo, ngaleyo ndlela kuvinjelwe ukuqhekeka kokhonkolo.

I-5. I-Hydroxyyethyl methyl cellulose (hemc, hydroxyethyl methyl celtule)
I-HydroxyYethylmethylcellellose ikhiqizwa ukwethula amaqembu we-hydroxyethyl ku-methylcellulose. IHemc ihlanganisa izici ze-HEC ne-MC, inokugcinwa kwamanzi okuhle nokuqina kwezindawo, futhi kungathuthukisa ukusebenziseka nokuqina kokhonkolo. Isetshenziswa kabanzi ngokhonkolo, ikakhulukazi ku-datar-welveling udaka nodumo olushisayo lokufakelwa. I-Hemc ingathuthukisa ngempumelelo ukusebenza kokwakha, inciphise ukulahleka komswakama emongolweni, futhi uvikele imifantu ngemuva kokomiswa.

I-6. I-ethyl cellulose (EC, ethyl cellulose)
I-Ethylcellose ikhiqizwa ngokubuyisela amaqembu ama-hydroxyl kuma-molecule we-cellulose ngamaqembu we-ethoxy (-Oc2hh5). I-EC ayivamisile ukusetshenziswa ngokhonkolo, kepha idlala indima ebalulekile kukhonkolo okhethekile onjengokhonkolo onamandla okhonkolo kanye nokhonkolo ozenzelayo. I-EC inezakhiwo ezinhle zokuqina nokubopha futhi ingathuthukisa amandla nokuvimbela ukhonkolo. Ngaphezu kwalokho, i-EC ibuye ibe nokumelana okuhle kwamakhemikhali nokuqina okushisayo, ngakho-ke ingasetshenziswa ngempumelelo kwezinye izindawo ezikhethekile.

7. Methyl hydroxyyethyl cellulose (Mhec, Methyl hydroxyethyyl celtule)
I-methyl hydroxyyethyl celtulose ihlanganisa izici ze-MC ne-HEC futhi inokuqina okuhle, ukugcinwa kwamanzi kanye nokuphumula. Iqhaza eliphambili le-MHEC ngokhonkolo ukuthuthukisa izakhiwo ze-bonding kanye nokuvimbela ukhonkolo. Kusetshenziswa kabanzi ku-ukhonkolo ozenzayo nokulungisa.

I-Cellulose Afers isetshenziswa kabanzi ngokhonkolo futhi inezinhlobo ezahlukahlukene. Izinhlobo ezahlukahlukene ze-cellulose 'tilers zinezinhlaka ezahlukene zamakhemikhali kanye nezinto ezibonakalayo futhi zingahlangabezana nezidingo zamaphrojekthi ahlukile. Ukukhetha uhlobo lwe-cellulose lwe-cellulose lwe-cellulose kungathuthukisa kakhulu ukusebenziseka, amandla nokuqina kokhonkolo, ngaleyo ndlela kwandise ikhwalithi kanye nokwethenjwa kwamaphrojekthi wokwakha. Kuzinhlelo zokusebenza ezisebenzayo, kuyadingeka ukuthi ukhethe uhlobo lohlobo kanye nomthamo we-cellulose ether esekelwe kwizidingo ezithile zobunjiniyela nemibandela yokwakha ukuze uzuze umphumela omuhle kakhulu.
