1. Impahla eluhlaza ye-cellulose ether
I-Cellulose ether yokwakha i-polymer engancibiliki emanzini engeyona i-ionic umthombo wayo:
I-Cellulose (i-wood pulp noma i-cotton linter), i-halogenated hydrocarbons (i-methane chloride, i-ethyl chloride noma amanye ama-halide amaketanga amade), ama-epoxy compounds (i-ethylene oxide, i-propylene oxide, njll.)
I-HPMC-Hydroxypropyl Methyl Cellulose Ether
I-HEC-Hydroxyethyl Cellulose Ether
I-HEMC-Hydroxyethyl Methyl Cellulose Ether
I-EHEC-Ethyl Hydroxyethyl Cellulose Ether
I-MC-methyl cellulose ether
2. Izici ze-cellulose ether
Izici ze-cellulose ethers zincike kulokhu:
I-Polymerization degree DP Inani lamayunithi e-glucose-viscosity
Ama-substitute kanye nezinga lawo lokushintsha, izinga lokufana lokushintshwa —- nquma inkambu yesicelo
Usayizi Wezinhlayiyana—-Ukuncibilika
Ukwelashwa kwendawo (okungukuthi, ukuchithwa okubambezelekile)—-isikhathi se-viscosity sihlobene nenani le-pH lesistimu
Idigri yokuguqulwa—-Thuthukisa ukumelana ne-sag nokusebenza kwe-cellulose ether.
3. Indima ye-cellulose ether - ukugcinwa kwamanzi
I-Cellulose ether iyinhlanganisela yeketango le-polymer elakhiwe amayunithi e-β-D-glucose.Iqembu le-hydroxyl ku-molecule kanye ne-athomu yomoya-mpilo ku-ether bond akha isibopho se-hydrogen ne-molecule yamanzi, ekhangisa i-molecule yamanzi ebusweni beketango le-polymer futhi ibophe ama-molecule.Kulolu chungechunge, ibambezela ukuhwamuka kwamanzi futhi imuncwa ungqimba oluyisisekelo.
Izinzuzo ezihlinzekwa yizindawo zokugcina amanzi ze-cellulose ethers:
Asikho isidingo sokumanzisa isendlalelo sesisekelo, inqubo yokulondoloza
ukwakhiwa okuhle
amandla anele
4. Indima ye-cellulose ether - umphumela wokuqina
I-Cellulose ether ingakhuphula ukuhlangana phakathi kwezingxenye zodaka olusekelwe ku-gypsum, okubonakala ekwandeni kokuvumelana kodaka.
Izinzuzo eziyinhloko ezihlinzekwa ukuqina kwe-cellulose ethers yilezi:
Nciphisa umlotha womhlabathi
Khulisa ukunamathela kusisekelo
Yehlisa ukuwohloka kodaka
gcina udaka
5. Indima ye-cellulose ether - umsebenzi ongaphezulu
I-Cellulose ether iqukethe amaqembu e-hydrophilic (amaqembu e-hydroxyl, amabhondi e-ether) namaqembu e-hydrophobic (amaqembu e-methyl, amaqembu e-ethyl, izindandatho ze-glucose) futhi i-surfactant.
(I-top tension yamanzi ngu-72mN/m, i-surfactant ingu-30mN/m, kanti i-cellulose ether yi-HPC 42, HPMC 50, MC 56, HEC 69, CMC 71mN/m)
Izinzuzo eziyinhloko ezihlinzekwa umsebenzi ongaphezulu we-cellulose ethers yilezi:
Umphumela wokungena komoya (ukuklwebha okubushelelezi, ukuminyana okumanzi okuphansi, imodulus enwebekayo ephansi, ukumelana nokuncibilika kweqhwa)
Ukumanzisa (kwandisa ukunamathela ku-substrate)
6. Izidingo ze-gypsum yokuplasta ekhanyayo ye-cellulose ether
(1).Ukugcinwa kwamanzi okuhle
(2).Ukusebenza kahle, akukho khekhe
(3).Iqoqo likhuhla bushelelezi
(4).I-anti-sagging enamandla
(5).Izinga lokushisa lejeli lingaphezulu kuka-75°C
(6).Izinga lokuqedwa okusheshayo
(7).Kungcono ukuba nekhono lokufaka umoya futhi uzinzise amabhamuza omoya odakeni
11. Unganquma kanjani umthamo we-cellulose ether
Ukuze ukhombe ukhonkolo, kuyadingeka ukuthi kugcinwe amanzi anele odakeni isikhathi eside ukuze kusebenze kahle futhi kugwenywe imifantu.Ngesikhathi esifanayo, i-cellulose ether igcina inani elifanele lamanzi isikhathi eside ukwenza udaka lube nenqubo yokuzinza yokuhlangana.
Inani le-cellulose ether lincike kulokhu:
I-viscosity ye-cellulose ether
Inqubo yokukhiqiza ye-cellulose ether
Okuqukethwe Okubalulekile Nokusatshalaliswa Kwe-Cellulose Ether
Ukusabalalisa Usayizi Wezinhlayiyana ze-Cellulose Ether
Izinhlobo nokwakheka kodaka olususelwa ku-gypsum
Umthamo wokumunca amanzi wesendlalelo sesisekelo
Ukusetshenziswa Kwamanzi Ngokusatshalaliswa Okujwayelekile Kodaka Olusekelwe eGypsum
Isikhathi sokusetha se-gypsum-based mortar
Ubukhulu bokwakha nokusebenza kokwakhiwa
Izimo zokwakha (ezifana nezinga lokushisa, isivinini somoya, njll.)
Indlela yokwakha (ukukhuhla ngesandla, ukufutha ngomshini)
