Cement dhaka: Kuronga uye gadzira

Simende slurry chinhu yakasimba chaizvo zvinhu, rakakurumidza anogadza uye anoomesa mumhepo. Kutanga kwarinovirira pagungano tembiricha 20. madhigirii kunoitika munenge matatu nepedyo ane awa. The Kugadzirisa anofanira kutevedzerwa hapana paya pane awa rimwe pashure gadziriro yayo, sezvo zvimwe zvinoita usisavaviri. Pane zvakasiyana-siyana simende - napo yenhengo dzayo. The akagadzirira mhinduro kwavo maererano nesimba compressive zvakasiyana.

How kuti simende dhaka

Kuti agadzirire samende slurry anofanira kusefa jecha uye simende kuburikidza nesefa pamwe buri dhayamita 3 mm. Ingredients vari metered volumetric mishonga uye zvakavhenganiswa kusvikira homogenous, uye kana zvakakodzera, sieved zvakare uye yakaoma musanganiswa Wakawedzerwa mvura, kusvikira mumwe achida ukobvu.

Paakapa nyere pamusoro pedenga unoitwa zvikuru yakaoma dhaka zvinosanganisira filler uye vaviri kunyorerana zvinoriumba: jecha, samende uye madota putty. Muchiitiko chino, unofanira kuwedzera imwe chikamu chairo kuti zvikamu zvitatu madota kusvika 15 zvikamu jecha.

Slurry inoshandiswa kugadzira kongiri mixes. Vakaisa manyoro kongiri butiro machipisi kana matting, zvikuru wetting mvura. Izvi zvinonyanya kuitwa mumazuva mashanu okutanga pashure rikaisa formwork, nokuti zvinangwa izvi anoshandiswawo polyethylene firimu kuti pave hwemvura maturo.

Cement dhaka: Kuronga

Cement dhaka nokuti kuvaka inogona kutengwa kana akaita pasina nokuda vachisanganisa zvimwe ratios ejecha jecha (kubvira 1 kusvika 3, zvichienderana vanoumba 1 kusvika 6). Zvinofanira kurangarirwa kuti manually kubudisa mhinduro kwete chete richikunetesa, asi zviri anenge kusingabviri zvakaenzana kuparadzira zvose zvinoumba pasina yakakodzera ruzivo. Anoshanda kushandisa chisanganiso (zvemaziso kana magetsi), izvo zvinogona zvose kutengwa uye dzokurenda, rakumbirwa neshamwari.

Very dzakakurumbira ari samende slurry, yaishandiswa nokuda mudziyo brickwork. Izvi zvinogona kushandisa marudzi maviri mhinduro - ejecha simende-lime. With wokutanga mhando dzichiisa mutoro inobereka masvingo uye nezvimwe zvinhu, apo murwiyo rechipiri rinoshandiswa kuti mamwe mapepa (batira yomukati masvingo), uye rinowedzera chete chikamu chiduku esimende.

Kana dhaka inoshandiswa muchando, zvakakodzera kushandisa antifreeze yokuvirisa, izvo hatibvumiri kuoma nechando mhinduro. Kunyange zvakadaro, pane imwe tembiricha pazasi 20 Celsius simende gobvu nani kuita, sezvo zvinoriumba izvi hadzishandi. Kushandisa mhinduro ine yokuvirisa siyana anogona kupiwa zvakafanira mukana wokushandiswa uye kufamba. Kuwedzera ductility mhinduro nenyanzvi vanhuwo shambuu wakawedzera nokudurura nehafu-fő ane pfuma nenzira cubic mita rimwe samende uremu. Munyu wakafanana antifreeze yokuvirisa, pasinei dzakawanda dzave, dira hazvifaniri kunzvenga chimiro efflorescence.

Ejecha kongiri zvibereko kupisa nemishonga wemisanganiswa iyo inoshandiswa pagadzirwe monolithic hurongwa foci ane moto rakavhurika, kuti firebox furnace masonry zvinogumbura. Kusika murazvo nemishonga refractory zvinogadzirisa akashandisa zvinotevera zvinoumba uye kukura. Kana mhinduro iri kushandiswa kuti kusika maronda ane moto rakavhurika, tora simende mucherechedzo haisi kudzika pane 400. To chimwe chikamu Wakawedzerwa zvikamu yakapwanyika ibwe maviri, zvinosanganisira tsvuku chidhinha, zvikamu zviviri kubva Goldstone jecha kana kubva wakaisvonaka tsvuku fireclay zvidhina, uye chetatu kubva jecha rakanaka. Kusika firebox kutora chete esimende, akapwanyika ibwe nezvidhinha uye firebricks vanhuwo jecha kukura 1: 2: 2: 0.33.
