Gypsum Retarders

Gypsum retarder ninyongeramusaruro ikoreshwa mubikorwa byubwubatsi kugirango igabanye igihe cyagenwe cyibikoresho bishingiye kuri gypsumu, nka plaque cyangwa sima ya gypsumu.Gypsum idinders ningirakamaro mubikorwa byubwubatsi aho byongerewe igihe cyo gukora cyangwa kugena igihe bisabwa kugirango habeho kuvanga neza, kubishyira mu bikorwa, no kurangiza ibicuruzwa bya gypsumu.

Imikorere ya Gypsum Retarders:

Igikorwa cyibanze cya gypsum retarders ni ugutinza igenamigambi ryibikoresho bishingiye kuri gypsumu mugucunga hydration reaction ya gypsum.Gypsum, imyunyu ngugu isanzwe iboneka igizwe na calcium sulfate dihydrate (CaSO4 · 2H2O), ihura n’imiti n’amazi kugirango ibe plaque cyangwa sima ya gypsumu.Iyi reaction, izwi nka hydration, ikubiyemo gusesa kristu ya gypsumu ikurikirwa no kongera korohereza, biganisha ku gukomera cyangwa gushiraho ibikoresho.

Mugutangiza imiti yihariye ya chimique nka retarders, inzira yo kuhira igenda gahoro, bityo bikongerera igihe cyakazi cyibicuruzwa bishingiye kuri gypsumu.Ubu buryo bwagutse bwo gukora butuma abakozi bubaka umwanya munini wo kuvanga, gusuka, gushiraho, no kurangiza, cyane cyane mubihe aho ahantu hanini hagomba gutwikirwa cyangwa amakuru arambuye agomba kugerwaho.

Ubwoko bwa Gypsum Retarders:

Ubwoko butandukanye bwimiti irashobora gukora nka gypsum retarders, buriwese hamwe nuburyo bwihariye bwibikorwa.Ubwoko busanzwe bwa gypsum retarders burimo:

1. Acide organique: Acide zimwe na zimwe za acide, nka acide citric cyangwa acide ya tartaric, zirashobora kubuza neza igenamigambi rya gypsumu muguhuza na calcium ion, zikenerwa mugutanga gypsumu.Iyi reaction igoye itinda umuvuduko wo gusenyuka kwa gypsumu no kugwa, bityo bikadindiza gahunda yo gushiraho.
2. Fosifate: Fosifate, harimo na fosifate ya sodium cyangwa potasiyumu fosifate, irashobora kandi gukora nk'inyuma mu gukora ibibyimba bya calcium ya fosifati idashobora gushonga, ibuza amazi ya kristu ya gypsumu.Fosifate ikora nkibisubira inyuma muburyo buke kandi akenshi bikoreshwa muguhuza nibindi byongeweho kugirango ugere kumwanya wifuza.
3. Ethers ya Cellulose: Ethers zimwe na zimwe za selile, nka methyl selulose cyangwa hydroxyethyl selulose, zirashobora kuba imbogamizi mu kwinjiza umubiri wa molekile zamazi no kubabuza kubona uduce duto twa gypsumu.Ubu buryo butinda umuvuduko wamazi mugabanya amazi yaboneka, bityo bikongerera igihe cyakazi cyibikoresho bishingiye kuri gypsumu.
4. Ibindi byongeweho: Ibindi bintu bitandukanye byongeramo imiti, harimo lignosulfonate, gluconates, cyangwa polymers, birashobora kandi kwerekana ibintu bidasubirwaho mugihe byinjijwe muri gypsumu.Izi nyongeramusaruro zirashobora gukorana nuduce twa gypsumu cyangwa guhindura imiterere ya rheologiya yuruvange, biganisha kubiranga gutinda kuranga.

Porogaramu ya Gypsum Retarders:

Abadindiza Gypsum basanga ikoreshwa cyane mumishinga yubwubatsi aho bikenewe igihe kinini cyo gukora cyangwa kugena igihe.Porogaramu zimwe zisanzwe zirimo:

1. Gupompa: Mubikorwa byo guhomeka, gypsum retarders yemerera abapompa umwanya munini wo gukoresha no gukoresha gips ya gypsumu kurukuta, hejuru, cyangwa hejuru yimitako mbere yuko ishyiraho.Ubu buryo bwagutse bwo gukora ni ingirakamaro cyane kugirango tugere ku ndunduro neza cyangwa ibishushanyo mbonera.
2. Gushushanya no Gushushanya: Gypsum retarders ikoreshwa mugukora ibicuruzwa bishingiye kuri gypsumu, casts, hamwe nibintu byubatswe, aho gushiraho neza no kubisobanura neza.Mugutinda igihe cyo gushiraho, abayikora barashobora kwemeza kuzuza ibishushanyo kimwe no kwirinda gukomera hakiri kare mugihe cyo gukina.
3. Kwuzuza Kwuzuza Kwubaka: Mubice byubwubatsi cyangwa icyuho kiri hagati yimbaho ​​ya gypsumu cyangwa ikibaho, retarders yongewe kumyanya ihuriweho na gypsumu kugirango birinde gukama imburagihe no guturika.Ibi bituma habaho guhuza udusanduku twa gypsum kandi tukemeza ko igihe kirekire, kitarangiritse.
4. Porogaramu Zidasanzwe: Abadindiza Gypsum barashobora kandi gukoreshwa mubikorwa byihariye, nko mugukora gypsumu ishingiye kuri gypsum, grout, cyangwa ibifuniko byanditse, aho byongerewe igihe cyo gufungura cyangwa kugena igihe byifuzwa kugirango bikore neza.

Ibitekerezo no kwirinda:

Mugihe abadindiza gypsumu batanga inyungu nyinshi mubikorwa byubwubatsi, dosiye ikwiye hamwe no guhuza nibindi byongeweho bigomba gutekerezwa neza kugirango birinde ingaruka mbi kumikorere.Gukoresha cyane abadindiza birashobora kuganisha ku gihe kirekire cyo gushiraho cyangwa guhungabanya imiterere yubukorikori bwibikoresho bishingiye kuri gypsumu.Byongeye kandi, abayikora naba rwiyemezamirimo bagomba gukurikiza amabwiriza asabwa hamwe nuburyo bwo kwirinda umutekano mugihe bakora no gukoresha gypsum retard kugirango umutekano w abakozi ubuziranenge nibicuruzwa.

Mu gusoza, abadindiza gypsumu bafite uruhare runini mu nganda zubaka mu kongera igihe cyakazi no gushyiraho igihe cyibikoresho bishingiye kuri gypsumu.Byaba bikoreshwa muguhomesha, kubumba, kuzuza hamwe, cyangwa mubindi bikorwa, abadindiza bashoboza abahanga mubwubatsi kugera kubyo bifuza, imiterere, nuburinganire bwuburinganire.Mugusobanukirwa imikorere, ubwoko, hamwe nibisabwa bya gypsum retarders, abafatanyabikorwa barashobora gukoresha neza izo nyongeramusaruro kugirango banoze ibikorwa byubwubatsi no kuzamura umusaruro wumushinga.
