Ibanga lezixhobo zokwakhai-cellulose ethersisithako esibalulekileyo sekhemikhali esisebenzayo, esisetyenziswa kakhulu kwizixhobo zokwakha, ezifana nesamente, ikhonkrithi, udaka olomileyo, njl.
1. Ulwakhiwo lweekhemikhali kunye nokuhlelwa kwazo
I-Cellulose ether yi-polymer compound eyenziwe ngokuguqulwa kweekhemikhali kwe-cellulose yendalo. Icandelo layo eliphambili liqela le-hydroxyl le-cellulose eliguqulwe yi-etherifying agent (njenge-vinyl chloride, i-acetic acid, njl.njl.). Ngokweendidi ezahlukeneyo ze-etherifying, inokwahlulwa ibe ziindidi ezahlukeneyo ze-cellulose ethers, ikakhulu kuquka i-hydroxypropyl methylcellulose (HPMC), i-hydroxyethyl cellulose (HEC) kunye ne-methyl cellulose (MC).
2. Ukugcinwa kwamanzi
I-cellulose ether yezinga lezixhobo zokwakha ineempawu ezintle zokugcina amanzi, nto leyo enokuphucula ngempumelelo amandla okugcina amanzi e-mortar kunye ne-concrete. Oku kuphucula ukusebenza kwezinto ngexesha lokwakha kwaye kunciphisa ukuqhekeka kunye nokulahleka kwamandla okubangelwa kukufuma kwamanzi.
3. Ukutyeba
I-Cellulose ether ineempawu ezilungileyo zokutyeba, ezinokuphucula ukutyibilika kunye nokuxinana kwezinto zokwakha, okwenza kube lula ukuzisebenzisa ngexesha lokwakha. Ukutyeba kunceda ukuphucula uzinzo lwezinto kunye nokuthintela ukuqhekeka kunye nokubola.
4. Ukunciphisa amanzi
Ukuya kwinqanaba elithile,ii-ether ze-celluloseinokunciphisa ubungakanani bamanzi kwikhonkrithi okanye kwisamente, ngaloo ndlela iphucula amandla kunye nokuqina kwezinto. Olu phawu luyenza ibaluleke kakhulu ekusetyenzisweni kwekhonkrithi esebenza kakhulu.
5. Ukusebenza kolwakhiwo
Izinto zokwakha ezine-cellulose ethers zisebenza ngcono ngexesha lokwakha, nto leyo enokwandisa ixesha lokwakha kwaye inciphise iingxaki zokwakha ezibangelwa kukoma. Ukongeza, zinokuphucula ukunamathela kwe-mortar kwaye zonyuse ukunamathela kwezinto zokugquma.
6. Ukumelana nokuqhekeka
Ii-cellulose ethers zinokuphucula ukumelana nokuqhekeka kwe-mortar kunye ne-concrete kwaye zinciphise ukuqhekeka okubangelwa kukutshintsha kobushushu okanye ukuncitshiswa kokoma. Oku kubalulekile ukuze izakhiwo zihlale zizinzile ixesha elide kwaye zibukeke kakuhle.
7. Ukuziqhelanisa nokuhambelana
Ii-cellulose ethers zezinga lokwakha zihambelana kakuhle nezinto ezahlukeneyo zokwakha kwaye zinokuxutywa nesamente, i-gypsum, ii-polymers kunye nezinye izithako ngaphandle kokuchaphazela ukusebenza kwazo. Oku kuguquguquka kwenza ii-cellulose ethers zisetyenziswe kakhulu kwishishini lokwakha.
8. Ukhuseleko lokusingqongileyo
Ekubeni izinto ezisetyenziswayoii-ether ze-celluloseziphuma kwimicu yezityalo, zona ngokwazo zineempawu ezithile zokukhusela okusingqongileyo. Xa kuthelekiswa nezinye iipolymers zokwenziwa, i-cellulose ether inobuhlobo nokusingqongileyo xa isetyenziswa kwaye isetyenziswa kunyango lwenkunkuma.
9. Amasimi esicelo
I-cellulose ether yeklasi yezinto zokwakha isetyenziswa kakhulu kwiindidi ezahlukeneyo zezinto zokwakha, kuquka:
Udaka olomileyo: olufana nodaka olubophayo, udaka oluplastayo, njl.
Ikhonkrithi: ingakumbi ikhonkrithi esebenza kakhulu.
Ukwaleka: kungasetyenziselwa ukupeyinta udonga lwangaphakathi nolwangaphandle, ipeyinti yelatex, njl.
Iimveliso zeGypsum: ezifana nebhodi yegypsum kunye ne-gypsum putty.
10. Amanyathelo okusebenzisa
Xa usebenzisa i-cellulose ether yeklasi yokwakha, kufuneka unikele ingqalelo kula manqaku alandelayo:
Yongeza ngokwesilinganiselo esicetyiswayo, esigqithisileyo okanye esinganelanga kuya kuchaphazela ukusebenza kokugqibela.
Qinisekisa ukuba izinto ziyafana ngexesha lokuxuba ukuze kuthintelwe ukudibana kwezinto.
Xa ugcina, qwalasela ukungafumi ukuze uphephe ukufuma kunye nokuhlangana.
I-cellulose ether yezinga lezinto zokwakha iye yaba sisongezelelo esibalulekileyo kwishishini lezinto zokwakha ngenxa yeempawu zayo ezizodwa kunye nokusetyenziswa kwayo ngokubanzi. Ngokuphucuka okuqhubekayo kweemfuno zeshishini lokwakha zokusebenza kwezinto, amathuba okusetyenziswa kwe-cellulose ether aya kuba banzi.
