Kuqinise Dry Izingxube Isixazululo of

Usimende - akukhona okungokwemvelo isibopho bemvelo wezinto ezingaphili. Omunye eziyisisekelo futhi eyinhloko zokwakha. Ngokufaka liquid noma aqueous usawoti izixazululo, noma olunye uketshezi, ukwakha ingxube plastic kamuva Uqinisa ukwakha okuqinile. Lusebenza a zokwakha ukuze akhiqize eziphathekako ahlukahlukene izigqulo. Kuyinto ngokuyisisekelo ukuhluka nezinye amaminerali izinto esibophezelayo (lime noma Gypsum) yokuzigxilisa ngokuphelele ngaphandle. On amandla impahla ehlukaniswa amamaki, okuyinto obonakaliswe izinombolo kusuka 100 kuya 600, okusho ukuthi umuntu amandla compressive-10 - 60 MPA. grade Material 600 ubizwa ngokuthi "lempi" ngenxa yamandla abo futhi insimu ukusetshenziswa (ukuze kwakhiwe izakhiwo ezempi), futhi kubiza brand okuningi 500. Namuhla, le nto futhi yizigaba (30 kuya ku-60), okuyinto ibonisa amandla compressive (MPA). Umehluko omkhulu kusukela brand ukuthi ukumelana akuyona njengoba kusho futhi ucela engengaphansi kwengu-95% izinga, okungukuthi, 95 namazinga 100 kumele bahlangabezane ekilasini.

Mayelana ukukhiqizwa, usimende ikhiqizwa esebenzisa ukugaya esihle kakhulu Gypsum futhi clinker. Brick kulesi simo umphumela calcining eyohlobo phambi sintering ingxube homogeneous, okuyinto yakhiwa ubumba Ukwakheka nge aphakeme calcium silicate nomcako. Lapho ukugaya clinker Ufaka Gypsum ukuze ulungise isikhathi ukuqina, kufika ku-15% amaminerali izithasiselo obusebenzayo (pyrite, Cinders, uthuli flue, isihlabathi nokunye. PA) ukuze sithuthukise izakhiwo ezithile, uphinde wehlise izindleko impahla kokuqala. Kokudubula ingxube kokuqala Kwenziwa ezingeni lokushisa 1470 ° C ubude besikhathi 2 - hora 4 eside amaziko obukhethekile ukushisa okuhlangene exchange amadivayisi eklanyelwe lula synthesis efanelekayo usimende-matrix namaminerali.

lolu hlobo izinto, ngaphandle okuyinto ke siyingxenye ye isakhiwo namuhla - Kuyaziwa ukuthi usimende ezaziwayo. Vele kanjani intando okuningi okuhle esakhile Yiqiniso, ku inani isithakazelo, ukwakhiwa mfanelo kwabakhiqizi impahla kuncike ngokuqondile. Naphezu kahle kakhulu ukuthi eliphezulu usimende ingxube kufanele baziswa ngobuhlanya kuyabiza, ayidingekile amanani aphezulu. Manje, sekwenzeka ukuba esikhathini esinzima, abakhiqizi kanye nabasabalalisi ozama ukwenza uhlelo rastsenochnuyu ngconywana izinhlangothi zombili, ukuze silondoloze okufunekayo umncintiswano, futhi izinga akubi kunabayeni yaseYurophu, nakuba zobuchwepheshe ukukhiqizwa ukwehla ezingaqedwa nakakhulu. Abantu bakholelwa izinto ngisho ingxube usimende, babe nezici ezikhethekile. Le nhlanganisela ukuthi ezikhonjiswe izimpawu ngabanye: B - omiswe okusheshayo; C - sulfate futhi H - ingxube, esekelwe itshe Ukwakheka benganhlanhlathi (kwesejwayelekile).

Early amandla usimende libhekene ekukhuleni ukumelana esebenzayo esikhathini sokuqala ukuqina. Wasebenzisa ikakhulukazi womshini Precast izitshalo ukhonkolo kanye nemikhiqizo. High nokwethenjelwa mechanical ekuqaleni lapho uthela khona kuchazwe kahle nokumbiwa yokwakheka clinker ukuthungwa izithasiselo ngobukhulu futhi fineness. Sulphate noma inhlanganisela Portland usimende sulfate kukhulunywa abavamile Portland usimende has ukumelana eliphezulu kakhulu amanzi nosawoti, kancane ukushuba bamba okusezingeni eliphezulu ukumelana ezibandayo. travel Ukhonkolo futhi sezindiza izindlu, ibhuloho izakhiwo udinga ukusebenzisa usimende inhlanganisela senziwa ngesisekelo clinker kwesejwayelekile.
