Yiziphi izici ze-methyl cellulose ether?
Impendulo: Kungezwe inani elincane kuphela le-methyl cellulose ether, futhi ukusebenza okuqondile kwe-gypsum mortar kuzothuthukiswa kakhulu.
(1) Lungisa ukungaguquguquki
I-Methyl cellulose ether isetshenziswa njenge-thickener ukulungisa ukuhambisana kwesistimu.
(2) Lungisa isidingo samanzi
Ohlelweni lodaka lwe-gypsum, isidingo samanzi siyipharamitha ebalulekile.Isidingo samanzi esiyisisekelo, kanye nokukhishwa kodaka okuhlobene, kuncike ekwakhiweni kodaka lwe-gypsum, okungukuthi inani le-limestone, i-perlite, njll.Ukufakwa kwe-methyl cellulose ether kungalungisa ngempumelelo isidingo samanzi kanye nokuphuma kodaka lwe-gypsum mortar.
(3) Ukugcinwa kwamanzi
Ukugcinwa kwamanzi kwe-methyl cellulose ether, umuntu angakwazi ukulungisa isikhathi sokuvula kanye nenqubo ye-coagulation yesistimu ye-gypsum mortar, ukuze ulungise isikhathi sokusebenza sesistimu;ama-methyl cellulose ether amabili angakhulula kancane kancane amanzi esikhathini eside Amandla okuqinisekisa ngempumelelo ukuhlangana phakathi komkhiqizo ne-substrate.
(4) Lungisa i-rheology
Ukwengezwa kwe-methyl cellulose ether kungalungisa ngokuphumelelayo i-rheology yesistimu ye-gypsum yokufaka, ngaleyo ndlela ithuthukise ukusebenza kokusebenza: udaka lwe-gypsum lusebenza kangcono, ukusebenza okungcono kwe-anti-sag, akukho ukunamathela ngamathuluzi wokwakha nokusebenza okuphezulu kwe-pulping, njll.
Ungakhetha kanjani i-methyl cellulose ether efanelekile?
Impendulo: Imikhiqizo ye-Methyl cellulose ether inezici ezihlukene ngokwendlela yazo ye-etherification, izinga le-etherification, i-viscosity yesisombululo esinamanzi, izinto ezibonakalayo ezifana nokucwenga kwezinhlayiyana, izici zokuncibilika nezindlela zokuguqula.Ukuze uthole umphumela wokusetshenziswa ongcono kakhulu, kuyadingeka ukukhetha uhlobo olulungile lwe-cellulose ether yezinkambu ezihlukene zohlelo lokusebenza, futhi uhlobo olukhethiwe lwe-methyl cellulose ether kufanele luhambisane nohlelo lodaka olusetshenzisiwe.
I-methyl cellulose ethers iyatholakala kuma-viscosities ahlukene ukuze ivumelane nezidingo ezahlukahlukene.I-Methyl cellulose ether ingadlala indima kuphela ngemva kokuchithwa, futhi izinga layo lokuqedwa kufanele livumelane nenkundla yesicelo kanye nenqubo yokwakha.Umkhiqizo oyimpushana ulungele izinhlelo zodaka ezixutshwe okomile (njenge-spray plaster plastering).Izinhlayiya ezinhle kakhulu ze-methyl cellulose ether zingaqinisekisa ukuqedwa ngokushesha, ukuze ukusebenza kwayo okuhle kakhulu kusetshenziswe ngokuphumelelayo esikhathini esifushane ngemva kokwakhiwa kodaka olumanzi.Kwenyusa ukungaguquguquki nokugcinwa kwamanzi kodaka ngesikhathi esifushane kakhulu.Lesi sici sifaneleka ngokukhethekile ekwakhiweni kwemishini, ngoba ngokuvamile, isikhathi sokuxuba amanzi kanye nodaka oluxubekile omile lufushane kakhulu ngesikhathi sokwakhiwa kwemishini.
Kuyini ukugcinwa kwamanzi kwe-methyl cellulose ether?
Impendulo: Ukusebenza okubaluleke kakhulu kwamabanga ahlukene e-methyl cellulose ether (MC) amandla abo okugcina amanzi ezinhlelweni zezinto zokwakha.Ukuze uthole ukusebenza kahle, kuyadingeka ukugcina umswakama owanele odakeni isikhathi eside.Ngenxa yokuthi amanzi asebenza njengesithambiso kanye nencibilikisi phakathi kwezingxenye ze-inorganic, ama-mortar anengqimba elincanyana angafakwa amakhadi futhi udaka olunamekiwe lungasakazwa ngamatrowel.Izindonga noma amathayela abambayo akudingeki ukuthi afakwe amanzi ngaphambili ngemva kokusebenzisa i-cellulose ether-added mortar.Ngakho i-MC ingaletha imiphumela yokwakha esheshayo neyongayo.
Ukuze usethe, izinto zikasimende ezifana ne-gypsum zidinga ukufakwa amanzi ngamanzi.Inani elizwakalayo le-MC lingagcina umswakama othulini isikhathi eside esanele, ukuze inqubo yokumisa nokuba lukhuni iqhubeke.Inani le-MC elidingekayo ukuze kutholwe umthamo owanele wokugcina amanzi lincike ekumunceni kwesisekelo, ukwakheka kodaka, ukujiya kongqimba lodaka, isidingo samanzi sodaka, kanye nesikhathi sokusetha sezinto zikasimende.
Uma usayizi wezinhlayiyana ze-MC ucolekile, udaka lushuba ngokushesha.
