Isingeniso se-Hydroxypropyl Methyl Cellulose HPMC ye-Drymix Mortar

IHydroxypropyl Methylcellulose (I-HPMC), ogama lakhe lesiShayina lingu-hydroxypropyl methylcellulose, i-semi-synthetic, i-non-ionic cellulose ether etholwe ngokushintsha amakhemikhali i-cellulose yemvelo. Le mpushana emhlophe ingakha isisombululo se-viscous esisobala ngemva kokuncibilika emanzini. Inokuqina okuhle kakhulu, ukugcinwa kwamanzi, ukuzinza kanye nezakhiwo zefilimu. Kuyisithasiselo esibalulekile semisebenzi eminingi emikhakheni eminingi njengokwakha.

Izici nezinzuzo ze-Hydroxypropyl Methyl Cellulose HPMC ye-Drymix Mortar

I-solubility enhle kakhulu yamanzi: Ingancibilika ngokushesha emanzini abandayo ukwenza isisombululo esicacile nesizinzile.

Ukuqina okusebenzayo kanye nekhono lokugcina amanzi: Khulisa i-viscosity yezinto, ngokuphumelelayo ukunciphisa ukuhwamuka kwamanzi, kanye nokwenza ngcono ukusebenza kahle.

Ukuzinza okuhle: Inokuqina okuhle kuma-asidi, ama-alkali, kanye nosawoti, futhi ifanele uhla olubanzi lwamanani e-pH.

Ukwakhiwa kwefilimu kanye nemiphumela yokuzivikela: Ngemva kokumisa, yakha ifilimu eqinile futhi esobala ukuvikela i-substrate futhi ivimbele ukungena kwamanzi kanye nokuhwamuka.

Ayinabuthi futhi ayicunuli: Ine-biocompatibility enhle futhi ifanele izinkundla zemithi nokudla.

Ukuguquguquka: Ngokushintsha izinga lokushintshwa kanye nesisindo samangqamuzana, ukusebenza kwayo kungalungiswa ukuze kuhlangatshezwane nezidingo ezahlukene zohlelo lokusebenza.

Ukubukeka Nohlobo Lomzimba

I-HPMC ibukeka njengemhlophe noma imhlophe, impushana egeleza mahhala. Ayinayo iphunga elibonakalayo futhi incibilika kalula emanzini abandayo ukuze kube nokucacile, ikhambi eliwugqinsi. Impushana ihlala ivikelekile ngaphansi kwezimo zesikhala esivamile futhi ayigobi lapho igcinwe yomile.

Ukuqina kwe-Array

I-Viscosity iyinkomba yokusebenza ebalulekile ye-HPMC ezinhlelweni ze-drymix. Izimfanelo ezivamile ezisetshenziswa odakeni ngokuvamile ziyehluka 4,000 ku 100,000 mPa · s (kunqunywa ku 2% ukugxilisa ingqondo, 20 °C). I-viscosity enkulu ithuthukisa ukugcinwa kwamanzi nokusebenza, kuyilapho i-viscosity encishisiwe isekela ukugeleza okungcono kakhulu nokudonsa.

Amazinga Okushintsha

Into iqukethe amadigri alawulwayo e-methoxy (– KANYE OKUBILI) kanye ne-hydroxypropoxy (– OCH OKUBILI CHOHCH AMAHLANU) amaqembu. Izinto ezivamile ze-methoxy ziwela phakathi 19% futhi 30%, kanye nokuqukethwe kwewebhu ye-hydroxypropoxy kusuka 4% ku 12%. Lokhu kushintsha kuqinisekisa ukuncibilika okulinganayo, ukwakheka kwefilimu, kanye nokuhambisana nezinhlelo zikasimende.

Okuqukethwe kwewebhu okunomswakama

Okuqukethwe umswakama kuhlala kubalwe ngezansi 5% ngesisindo. Izinsiza zokuswakama eziphansi zigcina ukugeleza kwempushana futhi zivimbele ukusabela kusenesikhathi ngesikhathi sokugcinwa noma ukuxutshwa.

Inani le-pH

A 2% isixazululo esiwuketshezi se-HPMC sibonisa i-pH phakathi 6.0 futhi 8.0 . Lezi zinhlobonhlobo ze-alkaline ezingathathi hlangothi ukuya kancane ziqinisekisa ukuhambisana nezingxenye zodaka ezivamile ezifana nosimende we-Rose city kanye nomcako..

Okuqukethwe kwe-Ash Web

Izinto zomlotha ziyaqhubeka nokuba ngaphansi 5%, okuphakamisa ukuhlanzeka okuphezulu kanye nezinsalela ezincane kakhulu ze-inorganic ngemva kokushiswa. Lokhu kusekela ukusebenza okungaguquki kanye nokwakheka okuhlelekile.

I-Fragment Dimension

Most bits travel through a 80-mesh screen (180 ama-microns). Usayizi wezinhlayiyana ezinhle ukhangisa ukuhlakazeka okusheshayo kanye ne-hydration engaguquki emixubeni eyomile.

Ukugcina Amanzi

I-HPMC ithuthukisa kakhulu ukugcinwa kwamanzi– ngokwedlulele 90% ekwakhekeni kwe-adhesive yesitezi esiyisisekelo noma ukwakheka kukakhonkolo. Lesi sakhiwo sibamba ukulahleka kwamanzi, ukunika amandla ukusimende okulungile nokuthuthuka kwebhondi eqinile.

Ukusebenza Okuthuthukisiwe Nokungaguquguquki

I-HPMC kwenza i-drymix mortar ibe lula kakhulu ukuyixuba, Hlakaza, kanye nesimo. Inikeza udaka olusha ukuthungwa okubushelelezi okuhlala kufana kulo lonke uhlelo lokusebenza. Abasebenzi bakuthola kunzima ukubhekana nakho, okwehlisa umzamo futhi kukhuphule izinga eliphezulu lomsebenzi.

Ukugcinwa Kwamanzi Okungcono

Umsebenzi owodwa obalulekile we I-HPMC ubamba amanzi odakeni. Lokhu kusiza usimende umswakama ngokuphelele, futhi ngezinsuku ezifudumele noma lapho isetshenziswa ezindaweni ezinezimbobo. Ukugcinwa kahle kwamanzi kusho ukunamathela okunamandla kakhulu kanye nokuphuka okuncane njengoba amakhambi odaka.

Ibhondi Ethuthukisiwe

I-HPMC kuqinisa ncamashi ukuthi udaka luhlala kanjani nezindonga, amathayili, noma ezinye izinto zokwakha. Lesi sibopho sihlala siqinile kancane kancane, ukunciphisa ingozi ye-delamination noma ukwehluleka ekusetheni amathayela e-ceramic kanye nezinhlelo ze-plaster.

Isikhathi Sokuvula Esiphethwe

Osonkontileka bokwakha bathola isikhathi esengeziwe sokulungisa amathayela noma izindawo ezibushelelezi ngaphambi kokuthi udaka luqale ukusethwa. I-HPMC yandisa lesi sikhathi esivulekile ngaphandle kokunciphisa ukuphulukiswa okuphelele. Leyo bhalansi isekela umsebenzi wokunemba futhi inciphisa ukumosha izinto ezibonakalayo.

Kwehlisiwe I-Sag ne-Slump

Lapho isetshenziswa phezulu naphansi noma ngaphezulu, udaka nge I-HPMC imelana nokunyakaza noma ukuhlehla. Le ndawo yokuhlala ye-anti-sag igcina izendlalelo zilingane futhi ivimbele ukushuba okungalingani noma ukuwa ngesikhathi sokoma.

Ukusebenza Okujwayelekile Kuzo zonke Izinkinga

I-HPMC Izinsiza ze-drymix zisebenza ngokunembile ezimweni zezulu ezihlukene nasezindaweni ezingaphansi ezihlukahlukene. Kungakhathaliseki ukuthi isetshenziswa ngaphakathi noma ngaphandle, udaka lugcina ukujikeleza okubikezelwayo, ukusetha ukuziphatha, namandla okugcina. Lokhu kuvumelana kuthuthukisa ukubala phakathi kochwepheshe nabacacisi ngokufanayo.

Iphrofayela Yenkampani
