1. Isingeniso
I-Methylcellose Ether (MCE), njengesengezo esibalulekile sokwakha, isetshenziswe kabanzi ezintweni zesimanje zokwakha, ikakhulukazi ku-gypsum ngodaka. UGenar kaGypsum usephenduke ukwaziswa okubalulekile emkhakheni wokwakha ngenxa yokusebenza kwawo okuhle, ukunamathela kanye nokugcinwa kwamanzi. Njenge-polymer compound, i-viscosity ye-methylcellose ether idlala indima ebalulekile ekuqondiseni ukusebenza ngodaka lwe-gypsum.
2. Izakhiwo kanye nenqubo yokwenza i-methylcellulose ether
2.1 Izici eziyisisekelo ze-methylcellulose ether
I-methylcellose eTher yi-polymer ancibilike enamanzi etholwe ukuguqulwa kwe-methylation. Iyunithi yalo yesakhiwo ikakhulukazi yakhiwa i-glucose. I-ether bond eyakhiwe yi-methylation ithuthukisa ukuqina kwayo kanye nokuqina okushisayo. I-Methylcellose Afers enama-degree ahlukene we-methylation kanye nezinsimbi zamangqamuzana zibonisa izici ezihlukile ze-viscosity, ezinomthelela omkhulu ohlelweni lwazo ezintweni zokwakha.
2.2 Umphumela we-methyl cellulose ether ku-gypsum udaka
Ku-gypsum udaka, i-methyl celtulose ether ikakhulukazi ithinta ukusebenza ngodaka ngezinqubo ezilandelayo:
Umphumela wokuqina: Ngokwandisa ukubonwa kodaka, ukuqina kokumiswa kodaka kuyathuthukiswa.
Ukugcinwa kwamanzi: Ngokwakheka isakhiwo senethiwekhi kudaka, ukulahlekelwa kwamanzi kuncishisiwe, ngaleyo ndlela kuthuthukise isikhathi sokusetha kanye nenqubo eqinile yodaka.
Ukwenza ngcono ukusebenza kokwakha: Ukuthuthukisa ukusebenziseka kodaka, ukunciphisa ukopha nokuhlukaniswa, kanye nokwenza ngcono ukunamathela.

3.2. I-Rheology
I-Vissusity ephezulu ye-methyl celtuleose ether ingakhuphula ukucindezela kwesivuno nokubonakala kwepulasitiki kodaka lwe-gypsum, okwenza udaka lubonise izakhiwo eziqinile ezilwa nokuvinjwa. Lokhu kubaluleke kakhulu ekwakhiweni ezindaweni ezibheke mpo, ezinganciphisa ukuhamba kodaka nokwenza ngcono ikhwalithi yokwakha. Kodwa-ke, ukuhlakanipha okuphezulu kakhulu kungenza udaka lube mkhulu futhi kunzima ukusebenza khona, futhi ibhalansi idinga ukutholakala emkhakheni wokwakha.
3.3. Ukugcinwa kwamanzi
Ukugcinwa kwamanzi kuyisici esibalulekile esithinta inqubo enzima ye-gypsum ngodaka. I-Vissusity ephezulu ye-methyl celtuleose ether ingathuthukisa kakhulu ukugcinwa kwamanzi kodaka ngenxa yesakhiwo senethiwekhi ye-denser eyakhiwe, ukuvimbela ukuqhekeka kusenesikhathi okubangelwa ukulahleka kwamanzi okusheshayo. Kodwa-ke, ukugcinwa kwamanzi okuphezulu kakhulu kungandisa isikhathi sokuqala nesokugcina sokugcina sodaka, okudinga ukulungiswa ngokuya ngesimo esithile sohlelo lokusebenza.
3.4. Umphumela wokusebenza kodaka
I-viscosity ye-methyl cellulose ether inomthelela obalulekile ekusebenzeni kukaGypsum Data:
3.5. Ukusebenza
I-Viscosity Elinganiselayo isiza ukuthuthukisa ukusebenziseka kodaka, okwenza kube bushelelezi futhi kube lula ukusebenza ngesikhathi sokwakha. I-Methyl Cellulose Ether ene-viscosity ephezulu kakhulu izokhulisa ukuvumelana ngodaka, yehlile ububi bawo, bese benza ukuthi kwakhiwe kube nzima. Ekwakhiweni kwangempela, kuyadingeka ukuthi ukhethe i-methyl cellulose ether nge-viscosity efanelekile ngokusho kwezidingo zokwakha ukuqinisekisa ukukhiqizwa okuhle.
3.6. Ukunamathela
I-viscosity ye-methyl cellulose ether inomthelela omkhulu ekunamathisweni kodaka. I-Vissusity ephezulu ye-methyl celtulose ether ingathuthukisa ukunamathela kodaka ku-substrate, thuthukisa amandla okunamathela kanye nekhono lokulwa nodaka. Lokhu kubaluleke kakhulu emisebenzini ebheke mpo nasezingeni eliphezulu, enganciphisa ukushelela nokuchithwa kodaka.
3.7. Umphumela wokuqina kodaka
I-viscosity ye-methyl cellulose ether ibuye ithinta ukuqina kodaka lwe-gypsum, ikakhulukazi ngaphansi komjikelezo omanzi kanye nemikhuba yomjikelezo we-freeze-thaw.
3.8. Umjikelezo omanzi owomile
Ukuvuzisa okuphezulu kwe-methyl celtuleose ether kungakha isakhiwo senethiwekhi esizinzile emotweni, ngaleyo ndlela sithuthukise ukumelana nodaka lokuqhekeka. Ngaphansi kwemibandela yomjikelezo owomile, udaka olunokubona okuphezulu kungagcina ubuqotho obungcono nokumelana nokuqhekeka.
3.9. Umjikelezo we-freeze-thaw
Ngaphansi kwemibandela yomjikelezo we-freeze-thaw, isakhiwo se-pore kanye nokugcinwa kwamanzi ngodaka kuba nethonya elibalulekile ekusebenzeni kwalo kwe-anti-freeze-freeze-free. I-viscosite ephezulu ye-methyl celtuleose ether inganciphisa ama-pores capillary ku-dungar
4. Izibonelo zohlelo lokusebenza nemiphumela yangempela
4.1 Ukusebenza kwama-methyl celtule
Ekwakheni, i-methyl celtulese tifers ene-visosities ehlukene isetshenziswa ngezikhathi ezahlukene. Isibonelo, ukulungiswa kodonga kanye ne-caulking kudinga abaphethe izithako eziphakeme ngokubona okuphezulu ukuhlinzeka ngozi olungcono oluthe mpo kanye nezakhiwo ezilwa nama-anti-sagging; Ngenkathi ukuzimela phansi kwephansi nezinye izinhlelo zokusebenza zidinga izithambiso ze-cellulose nge-viscosity ephansi yokuqinisekisa uketshezi oluhle.
4.2 Ukuhlaziywa Kwangempela Kwecala
Amacala angempela akhombisa ukuthi ukusetshenziswa kwe-viscosity ephezulu ye-methyllulose izitha zenqubo yokufaka odongeni kunganciphisa kakhulu udaka olukude futhi uthuthukise ukusebenza koMunga kanye nekhwalithi. Lapho ulinganisa umhlabathi, ukhetha i-suppleule
I-viscosity ye-methyl cellulose ether inomthelela omkhulu ekusebenzeni ngodaka lwe-gypsum. I-viscosite ephezulu ye-methyllulose ukuphana izithatha Ezisiza ukuthuthukisa ukugcinwa kwamanzi, anti-sagging kanye nokunamathelisa ngodaka, ngaleyo ndlela kuthuthukise izakhiwo zayo zomzimba nokusebenza kwayo. Kodwa-ke, ukubonwa okuphezulu kakhulu kungadala ukuthi udaka abe nohlobo lokunciphisa futhi lwenze ukwakha kube nzima.
