Ibanga lezinto zokwakhai-cellulose etheriyisengezo esibalulekile samakhemikhali esisebenzayo, esisetshenziswa kakhulu ezintweni zokwakha, njengosimende, ukhonkolo, udaka olomile, njll.
1. Isakhiwo samakhemikhali nokuhlukaniswa
I-Cellulose ether iyinhlanganisela ye-polymer eyakhiwe ukuguqulwa kwamakhemikhali kwe-cellulose yemvelo. Ingxenye yayo eyinhloko yiqembu le-hydroxyl le-cellulose elishintshwe yi-ejenti etherifying (njenge-vinyl chloride, i-acetic acid, njll.). Ngokwamaqembu e-etherifying ahlukene, ingahlukaniswa ngezinhlobo ezahlukene zama-cellulose ether, ikakhulukazi i-hydroxypropyl methylcellulose (HPMC), i-hydroxyethyl cellulose (HEC) ne-methyl cellulose (MC).
2. Ukugcinwa kwamanzi
Izinto zokwakha zebanga le-cellulose ether zinezakhiwo ezinhle kakhulu zokugcina amanzi, ezingathuthukisa ngempumelelo umthamo wokugcinwa kwamanzi odaka nokhonkolo. Lokhu kuthuthukisa ukusebenza kwempahla ngesikhathi sokwakhiwa futhi kunciphisa ukuqhekeka nokulahlekelwa amandla okubangelwa ukuhwamuka kwamanzi.
3. Ukuqina
I-Cellulose ether inezici ezinhle zokuqina, ezingathuthukisa i-fluidity kanye ne-viscosity yezinto zokwakha, okwenza kube lula ukusebenza ngesikhathi sokwakha. Ukujiya kusiza ukuthuthukisa ukuzinza kwento futhi kuvimbele ukuhlukaniswa kanye ne-sedimentation.
4. Ukuncishiswa kwamanzi
Ngokwezinga elithile,i-cellulose ethersinganciphisa inani lamanzi kukhonkolo noma udaka, ngaleyo ndlela ithuthukise amandla nokuqina kwempahla. Lesi sici sikwenza kubaluleke kakhulu ekusetshenzisweni kokhonkolo osebenza kakhulu.
5. Ukusebenza kokwakha
Izinto zokwakha ezinama-cellulose ethers zinokusebenza kangcono ngesikhathi sokwakha, ezinganweba isikhathi sokwakha futhi zinciphise izinkinga zokwakha ezibangelwa ukomiswa. Ngaphezu kwalokho, bangakwazi futhi ukuthuthukisa ukunamathela kodaka futhi bathuthukise ukunamathela kwezinto zokugqoka.
6. Ukumelana nokuqhekeka
Ama-cellulose ether angathuthukisa ukumelana nokuqhekeka kodaka nokhonkolo futhi anciphise imifantu ebangelwa ukushintsha kwezinga lokushisa noma ukuncipha kokuqina. Lokhu kubalulekile ekuzinzeni kwesikhathi eside kanye nobuhle bezakhiwo.
7. Ukuzivumelanisa nezimo nokuhambisana
Ama-ethers e-cellulose ebangeni lezinto zokwakha anokuhambisana okuhle nezinto ezihlukahlukene zokwakha futhi angaxutshwa nosimende, i-gypsum, ama-polymers nezinye izithako ngaphandle kokuphazamisa ukusebenza kwazo. Lokhu kuvumelana nezimo kwenza ama-cellulose ether asetshenziswe kabanzi embonini yezokwakha.
8. Ukuvikelwa kwemvelo
Kusukela izinto zokusetshenziswa zei-cellulose etherszithathwe emicu yezitshalo, zona ngokwazo zinezici ezithile zokuvikela imvelo. Uma kuqhathaniswa namanye ama-polymers okwenziwa, i-cellulose ether ihambisana kakhulu nemvelo ekusetshenzisweni nasekulapheni imfucuza.
9. Izinkambu zokufaka isicelo
Izinto zokwakha zebanga le-cellulose ether zisetshenziswa kabanzi ezintweni ezahlukahlukene zokwakha, kufaka phakathi:
Udaka olomile: njengodaka olubophayo, udaka lokuplasta, njll.
Ukhonkolo: ikakhulukazi ukhonkolo osebenza kakhulu.
I-Coating: ingasetshenziselwa izindonga zangaphakathi nezangaphandle, upende we-latex, njll.
Imikhiqizo ye-Gypsum: njengebhodi le-gypsum ne-gypsum putty.
10. Izinyathelo zokuphepha zokusetshenziswa
Uma usebenzisa i-cellulose ether yebanga lezinto zokwakha, udinga ukunaka amaphuzu alandelayo:
Engeza ngokwesilinganiso esinconyiwe, okweqile noma okunganele kuzothinta ukusebenza kokugcina.
Qinisekisa ukufana ngesikhathi sokuxuba ukuze ugweme ukuhlangana.
Lapho ugcina, naka umswakama-bufakazi ukuze ugweme umswakama kanye ne-agglomeration.
I-ether ye-cellulose ether yebanga lezinto zokwakha isiphenduke isengezo esibalulekile embonini yezinto zokwakha ngenxa yezakhiwo zayo eziyingqayizivele nokusebenza okubanzi. Ngokuthuthukiswa okuqhubekayo kwezidingo zemboni yezokwakha ekusebenzeni kwempahla, amathuba okusetshenziswa kwe-cellulose ether azoba banzi.
