Ibakala lezinto zokwakhai-cellulose etheryinto ebalulekileyo yokongeza imichiza esebenzayo, esetyenziswa ngokubanzi kwizinto zokwakha, ezifana nesamente, ikhonkrithi, udaka olomileyo, njl.
1. Ubume beekhemikhali kunye nokuhlelwa
I-ether ye-cellulose yi-polymer compound eyenziwe ngokuguqulwa kweekhemikhali ze-cellulose yendalo. Icandelo layo eliphambili liqela le-hydroxyl ye-cellulose eguqulelwe yi-agent etherifying (njenge-vinyl chloride, i-acetic acid, njl.). Ngokwamaqela ahlukeneyo etherifying, inokwahlulwa ibe ziindidi ezahlukeneyo ze-cellulose ethers, ingakumbi i-hydroxypropyl methylcellulose (HPMC), i-hydroxyethyl cellulose (HEC) kunye ne-methyl cellulose (MC).
2. Ukugcinwa kwamanzi
Izinto zokwakha zebakala i-cellulose ether ineempawu ezigqwesileyo zokugcina amanzi, ezinokuphucula ngokufanelekileyo umthamo wokugcinwa kwamanzi odaka kunye nekhonkrithi. Oku kwandisa ukusebenza kwezinto ngexesha lokwakhiwa kunye nokunciphisa ukukrazula kunye nokulahlekelwa kwamandla okubangelwa ukuguquka kwamanzi.
3. Ukutyeba
I-ether ye-cellulose ineempawu ezintle zokuqina, ezinokuthi ziphucule i-fluidity kunye ne-viscosity yezinto zokwakha, okwenza kube lula ukusebenza ngexesha lokwakha. Ukutyeba kunceda ekuphuculeni ukuzinza kwezinto kunye nokuthintela i-stratification kunye ne-sedimentation.
4. Ukuncitshiswa kwamanzi
Ukusa kumlinganiselo othile,i-cellulose ethersinokunciphisa ubuninzi bamanzi kwikhonkrithi okanye udaka, ngaloo ndlela iphucula amandla kunye nokuqina kwezinto. Olu phawu lwenza kubaluleke kakhulu ekusetyenzisweni kwekhonkrithi ephezulu.
5. Ukusebenza kolwakhiwo
Izinto zokwakha kunye ne-cellulose ethers zisebenza kangcono ngexesha lokwakha, ezinokwandisa ixesha lokwakha kunye nokunciphisa iingxaki zokwakha ezibangelwa ukomisa. Ukongeza, banokuphinda baphucule ukunamathela kodaka kwaye baphucule ukuncamathela kwezinto zokugquma.
6. Ukuxhathisa i-crack
I-cellulose ethers inokuphucula ukuxhathisa kokuqhekeka kodaka kunye nekhonkrithi kunye nokunciphisa iintanda ezibangelwa utshintsho lweqondo lokushisa okanye ukomisa ukuncipha. Oku kubalulekile kuzinzo lwexesha elide kunye nobuhle bezakhiwo.
7. Ukuguquguquka kunye nokuhambelana
Izinto zokwakha zebakala le-cellulose ethers zihambelana kakuhle kunye neentlobo zezixhobo zokwakha kwaye zinokuxutywa nesamente, i-gypsum, iipolymers kunye nezinye izithako ngaphandle kokuchaphazela ukusebenza kwazo. Oku kuguquguquka kwenza ukuba i-cellulose ethers isetyenziswe ngokubanzi kushishino lokwakha.
8. Ukhuseleko lokusingqongileyo
Ekubeni izinto ekrwada yei-cellulose ethersziphuma kwimicu yezityalo, zona ngokwazo zineempawu ezithile zokusingqongileyo. Xa kuthelekiswa nezinye iipholima zokwenziwa, i-cellulose ether ihambelana nokusingqongileyo ekusebenziseni kunye nonyango lwenkunkuma.
9. Iinkalo zesicelo
Umgangatho wokwakha i-ether cellulose isetyenziswa ngokubanzi kwizinto ezahlukeneyo zokwakha, kubandakanya:
Udaka olomileyo: olufana nodaka oludibanisayo, udaka lokutyabeka, njl.
Ikhonkrithi: ngokukodwa ikhonkrithi ephezulu yokusebenza.
I-Coating: ingasetyenziselwa ngaphakathi nangaphandle kweendonga zodonga, ipeyinti ye-latex, njl.
Iimveliso zeGypsum: ezifana nebhodi yegypsum kunye ne-gypsum putty.
10. Imiqathango yokusetyenziswa
Xa usebenzisa izinto zokwakha zodidi lwe-cellulose ether, kufuneka ubeke ingqalelo kula manqaku alandelayo:
Yongeza ngokomlinganiselo ocetyiswayo, ukugqithisa okanye ukungonelanga kuya kuchaphazela ukusebenza kokugqibela.
Qinisekisa ukufana ngexesha lokuxuba ukuthintela ukudityaniswa.
Xa ugcina, nikela ingqalelo kubungqina bokufuma ukunqanda ukufuma kunye ne-agglomeration.
I-ether ye-cellulose ether yomgangatho wezinto zokwakha iye yayinto eyongezelelweyo kwishishini lezinto zokwakha ngenxa yeempawu zayo ezizodwa kunye nokusebenza okubanzi. Ngokuphuculwa okuqhubekayo kweemfuno zoshishino lwezokwakha ekusebenzeni kwezinto eziphathekayo, amathuba okusetyenziswa kwe-cellulose ether aya kuba banzi.
