Incazelo Yomkhiqizo
INOMBOLO YE-CAS:9004-65-3
IHydroxypropyl Methylcellulose(HPMC), ebizwa nangokuthi i-hypromellose, iwuhlobo lwe-non-ionic cellulose ether.I-semi-synthetic, engasebenzi, i-viscoelastic polymer.Ivame ukusetshenziswa ku-ophthalmology njengomnyango wokugcoba, noma njenge-excipient noma i-excipient emithini yomlomo.Ivame ukutholakala ezinhlotsheni ezahlukene zempahla.Njengesengezo sokudla, i-hypromellose ingadlala izindima ezilandelayo: i-emulsifier, i-thickener, i-ejenti yokumisa futhi ibambele i-gelatin yezilwane, esebenza njenge-thickener, i-binder, ifilimu-yangaphambili, i-surfactant, i-colloid evikelayo, i-lubricant, i-emulsifier, kanye nokumiswa nokugcinwa kwamanzi. usizo.
I-Hydroxypropyl Methylcellulose (HPMC) Ibanga Lokwakha lingabonwa njengetemu elivamile le-etherification cellulose ether exubile.Okuvamile kulawa ma-cellulose ethers i-methoxylation.Ukwengeza, ukusabela kungafinyelelwa nge-propylene oxide.Singahlinzeka kokubili ibanga elingaguquliwe kanye nebanga eliguquliwe i-HPMC/MHPC, enesikhathi eside evulekile, ukugcinwa kwamanzi okuhle, ukusebenza okuhle kakhulu kanye Nokumelana Okuhle kokushelela njll.
I-Hydroxypropyl Methylcellulose (HPMC) IBanga Lokwakha lisetshenziswa kakhulu ekunamathiselweni kwe-Tile, udaka olomile oluxubene, i-wall putty, i-Skim coat, i-joint filler, ukuzilinganisa, usimende kanye ne-gypsum based plaster njll.

Izinkambu zohlelo lokusebenza
1.Ukwakha:
Njenge-ejenti egcina amanzi kanye ne-retarder yodaka lukasimende, yenza udaka lumpompeke.Isetshenziswa njenge-binder ku-plaster, i-putty powder noma ezinye izinto zokwakha ukuze kuthuthukiswe ukusabalala nokwelula isikhathi sokuvula.Indawo yokugcina amanzi ye-hydroxypropyl methylcellulose HPMC ivimbela udaka ekuqhekekeni ngenxa yokoma ngokushesha ngemva kokufakwa, futhi ithuthukisa amandla ngemva kokuqina.
1) Izinamatheliso zamathayela
Izinamathiselo zamathayela ezijwayelekile zigcwalisa zonke izimfuneko zamandla okunamathela okuqinile zokunamathela kwethayela le-C1.Ongakukhetha bangaba nokumelana nokushelela okuthuthukisiwe noma isikhathi sokuvula esinwetshiwe .Okunamathelayo kwethayela okujwayelekile kungaba isilungiselelo esivamile noma isilungiselelo esisheshayo .
Izinamatheliso zamathayela kasimende kufanele kube lula ukuzidonsa.Kufanele banikeze isikhathi eside sokushumeka, ukumelana nokushelela okuphezulu namandla anele okunamathela.Lezi zakhiwo zingathonywa yi-HPMC.Izinamatheliso zokubeka ibhulokhi zisetshenziselwa ukwakha izindonga zamabhulokhi kakhonkolo ane-aerated, izitini ze-sand-lime noma izitini ezijwayelekile.Izinamathiselo zamathayela ziqinisekisa isibopho esihle kakhulu phakathi kwe-substrate namabhodi okuvikela.I-HPMC ithuthukisa ukusebenza kwezinamathelisi zamaThayela futhi ikhuphule kokubili ukunamathela nokungaguquki.
•Ukusebenza okungcono: ukuthambisa kanye nepulasitiki yokhonkolo kuyaqinisekiswa, udaka lungasetshenziswa kalula futhi ngokushesha.
•Ukugcinwa kahle kwamanzi: isikhathi eside sokuvula sizokwenza ukufaka amathayela kusebenze kahle.
•Ukunamathela okuthuthukisiwe nokumelana nokushelela: ikakhulukazi amathayela asindayo.
2) Udaka oluxubile olomile
Udaka olomile oluxubene luyingxube yezibophezelo zamaminerali, ama-aggregates kanye nama-axiliary.Ngokuya ngenqubo, kunomehluko phakathi kokusebenza kwesandla nomshini.Zisetshenziselwa ukumboza isisekelo, ukufakwa, ukuvuselela kanye nezinhloso zokuhlobisa.Udaka oluxubekile olomile olusekelwe kusimende noma usimende / umcako we-hydrated ungasetshenziswa emsebenzini wangaphandle nangaphakathi.Ukunikezwa okufakwe ngomshini kuxutshwa emishinini yokuplasta eqhubekayo noma engasebenzi.Lokhu kuvumela ukumbozwa kwezindawo ezinkulu zodonga nophahla ngendlela esebenza kahle kakhulu.
•Ifomula yengxube eyomile elula ngenxa yokuncibilika kwamanzi abandayo: ukwakheka kwesigaxa kungagwenywa kalula, kulungele amathayela asindayo.
•Ukugcinwa kahle kwamanzi: ukuvimbela ukulahlekelwa uketshezi kuma-substrates, okuqukethwe kwamanzi afanelekile kugcinwa kuyingxube eqinisekisa isikhathi eside sokuqina.
3) Ukuzilinganisa
Izinhlanganisela zaphansi ezizilinganisa ngokwazo zisetshenziselwa ukwenza bushelelezi futhi zileveli zonke izinhlobo zama-substrate futhi zingasetshenziswa njengendawo yokubeka phansi isib. amathayela nokhaphethi.Ukuze ugweme ukubola kanye nokugcina ukugeleza, amabanga aphansi we-viscosity HPMC asetshenziswa.
• Ukuvikelwa ekukhishweni kwamanzi kanye nokushiswa kwenhlabathi.
•Awukho umthelela ku-slurry fluidity nge-viscosity ephansi
I-HPMC, kuyilapho izici zayo zokugcina amanzi zithuthukisa ukusebenza kokuqeda phezulu.
4) I-Crack Filler
·Ukusebenziseka okungcono: ukujiya okufanele kanye nepulasitiki.
·Ukugcinwa kwamanzi kuqinisekisa isikhathi eside sokusebenza.
·Ukumelana ne-Sag: ikhono elithuthukisiwe lokubopha udaka.
5) I-Gypsum based Plaster
I-Gypsum iyimpahla yokwakha esungulwe kahle yezicelo zangaphakathi.Inikeza ukusebenza okuhle futhi isikhathi sayo sokusetha singashintshwa kulo lonke uhlelo lokusebenza njengoba kudingeka.Izinto zokwakha ze-Gypsum zikhiqiza umoya wokuphila onethezekile ngenxa yebhalansi yomswakama omuhle.Ukwengeza, i-gypsum ibonisa ukumelana nomlilo okuhle kakhulu.Kodwa-ke, akukwazi ukumelana namanzi, ngakho-ke ukusetshenziswa kwangaphakathi kuphela kungenzeka.Inhlanganisela ye-gypsum kanye ne-hydrated lime ivame kakhulu ekwakhiweni kwe-plaster.
•Ukwanda kwesidingo samanzi: isikhathi esivulekile esikhulayo, indawo enwetshiwe ye-spry kanye nokwakhiwa ngendlela eyongayo.
•Ukusabalala okulula nokuthuthukisa ukumelana nokuhlehla ngenxa yokungaguquguquki okuthuthukisiwe.
I-6) I-wall putty / i-Skimcoat
•Ukugcinwa kwamanzi: kukhuliswe okuqukethwe kwamanzi ngodaka.
•Ukunqanda ukucwila: uma usakaza ukonakala kwejazi elikhudlwana kungagwenywa.
•Ukwanda kwesivuno sodaka: kuye ngesisindo sengxube eyomile nokwakheka okufanele, i-HPMC ingakhuphula umthamo wodaka.
7) I-Insulation yangaphandle kanye nohlelo lokuqeda (EIFS)
Izinamatheliso zombhede omncane osimende zisetshenziselwa ukunamathela kuthayela we-ceramic, ukwakha izindonga zikakhonkolo one-aerated noma izitini zamatshe e-lime kanye nokufaka izinhlelo zokuqeda insulating yangaphandle (EIFS) .Zinikeza ukusebenza okulula nokulula, ukusebenza kahle okuphezulu nokuqinisekisa ukuqina isikhathi eside.
•Ukunamathela okuthuthukisiwe.
•Ikhono elihle lokumanzisa lebhodi le-EPS ne-substrate.
•Kuncishiswe ukungena komoya nokungena kwamanzi.
1. Imboni yezokwakha: Njenge-ejenti egcina amanzi futhi ibuyisela emuva udaka lukasimende, yenza udaka lumpompeke.Isetshenziswa njenge-binder ku-plaster, ukhonkolo, i-putty powder noma ezinye izinto zokwakha ukuze kuthuthukiswe ukusabalala nokwelula isikhathi sokusebenza.Ingasetshenziselwa ukunamathisela amathayili e-ceramic, imabula, umhlobiso wepulasitiki, unamathisele isithuthukisi, futhi inganciphisa nenani likasimende.Indawo yokugcina amanzi ye-hydroxypropyl methylcellulose HPMC ivimbela udaka ekuqhekekeni ngenxa yokoma ngokushesha ngemva kokufakwa, futhi ithuthukisa amandla ngemva kokuqina.
