Mfundo ndi mitundu ya teknoloji yopangira thovu

Ndi chiyani jenereta ya thovu?

Mosasamala kanthu za jenereta ya thovu, mfundo yaikulu ya kuchita thovu ndikulowetsa mpweya mu njira yothetsera thovu. Mitundu yosiyanasiyana ya kusintha ndi yosiyana poyambitsa gasi, kotero zotsatira zake zimakhalanso zosiyana.

Pali zinthu ziwiri zofunika kupanga thovu, imodzi ndi njira yothetsera thovu, ndipo chinacho ndi mpweya. Onsewa ndi ofunikira. Popanda njira yothetsera kuwomba, filimu yamadzimadzi yozungulira gasi sikanapanga ndipo sipadzakhala thovu. Ndipo popanda gasi, njira yothetsera thovu yokha sipanga thovu.

Mu dongosolo kuwira mapangidwe, njira yothetsera kuwomba ndi njira yobalalitsira, mpweya ndi gawo lobalalika, ndipo mpweya umamwazikana mumadzimadzi kupanga thovu, ndiyeno mathovu ambiri amapanga thovu. Kuphatikiza pa chinthu chofunikira chowombera wothandizira, kulowetsedwa kwa gasi mu njira yothetsera mpweya ndi chinthu china chofunikira. Mfundo ya jenereta ya thovu ndiyo kuyambitsa gasi mumadzimadzi, kuti, jenereta ya chithovu imagwiritsa ntchito njira inayake kuti ilowetse gasi mumadzimadzi. Makina osiyanasiyana opangira thovu ali ndi njira zosiyanasiyana zopangira gasi. Mwambiri, pali njira zingapo zopangira gasi mu makina opangira thovu:

(1) Zitsamba zozungulira pang'onopang'ono zimabweretsa mpweya. Iyi ndi njira yobweretsera gasi mwachindunji mumatope (kapena matope a konkriti) kusakaniza ndi simenti thovu wothandizila. Pamene tsamba losakaniza likukankhira slurry, mpweya umalowa mu slurry ndi masamba osakaniza. Kuphatikiza apo, mpweya wambiri umakulungidwa mu slurry pamene slurry imatembenuzidwa, ndipo gawo la mpweya limabweretsedwa mu slurry ndi simenti ndi kuphatikiza. Kuchuluka kwa atatuwo ndi kuchuluka kwa mpweya womwe umalowa mu slurry. Mwa iwo, mpweya wobweretsedwa mu slurry ndi tsamba logwedezeka ndipo mpweya wokutidwa ndi tsamba lotembenuza slurry umatenga thupi lalikulu..

Pambuyo mpweya kulowa slurry, madzi amene ali ndi thovu surfactant surfactant mozungulira mpweya, kupanga kawiri-electron wosanjikiza madzi filimu pa mawonekedwe pakati pa mpweya ndi madzi, ndipo potsiriza amapanga thovu mu slurry mu mawonekedwe a mpweya-mu-zamadzimadzi.

Chifukwa cha pang'onopang'ono kasinthasintha liwiro masamba ndi mpweya wochepa anayambitsa motere, kuchuluka kwa thovu zomwe zimapangidwa ndizochepa, kutulutsa thovu sikuli bwino, ndipo mphamvu zake ndizochepa.

(2) Masamba othamanga kwambiri amayambitsa mpweya. Iyi ndi njira yobweretsera gasi munjira yowulutsira podalira zitsulo zothamanga kwambiri.. Kuyamba kwa gasi makamaka kumadalira mphamvu ya masamba ozungulira. Nthawi zambiri masamba amtunduwu amafunikira kuzungulira kothamanga kwambiri, liwiro liyenera kukhala> 700 rpm pa, zambiri pakati 700 ndi 1400 rpm pa, ndi liwiro la zotumphukira cha chochititsa mapeto ayenera kukhala> 20 m/s kuti mupeze zotsatira zokhutiritsa. Liwiro linalake limatha kuwonetsa choyikapocho kumadzimadzi, kukhudzana ndi mpweya, ndi kuyambitsa mpweya. Ngati liwiro ndilotsika kwambiri, chipolopolo sichidzawonetsedwa ndi madzi, ndipo kuchuluka kwa mpweya wotuluka magazi kudzakhala kochepa kwambiri. Liwiro loyenera liyenera kukhala lotsika kuposa momwe cholumikizira chimawonekera pamene madzi akuzungulira.

(3) Kugwiritsa ntchito kukakamiza kuyambitsa gasi. Iyi ndi njira yomwe imagwiritsidwa ntchito kwambiri ndi mpweya wopangidwa ndi thovu kunyumba ndi kunja. Ndi njira yasayansi yophunzitsira mpweya. Ndi pachimake cha thovu konkire mkulu-anzanu ndi sing'anga-anzanu thovu jenereta luso.

Njira ziwiri zomwe tazitchula pamwambazi ndizochepa komanso zosagwirizana, ndipo kuwira kwake ndi kwakukulu, makamaka kuwira m'mimba mwake sangathe kulamulidwa. Zimadalira kwathunthu kusasinthika kwa makina otulutsa thovu, ndipo sangathe kutsimikizira m'mimba mwake yaing'ono kuwira ndi yunifolomu thovu. Zizindikiro zaumisiri zofunika kwambiri. Nthawi yomweyo, kuchuluka kwa thovu n'kovuta kulamulira.

Pofuna kuthetsa mavuto omwe ali pamwambawa, njira yotulutsa thovu yotsatiridwa ndi kukakamizidwa idayamba. Ziribe kanthu ponena za kuchuluka kwa thovu, liwiro lotulutsa thovu, thovu m'mimba mwake ndi chithovu kufanana, ndi zina., aponda pamlingo watsopano ndipo apita patsogolo kwambiri paukadaulo. Mfundo yake yayikulu ndikugwiritsa ntchito zida zosiyanasiyana zomwe zimatha kupanga kuthamanga kwa mpweya kukanikizira mpweya mu gawo lamadzimadzi kuti mukwaniritse kusakanikirana kofanana kwa magawo awiriwa.. Pansi pa kukakamizidwa kwabwinobwino, ndizovuta kuti mpweya ulowe mumadzimadzi, koma pansi pa chipsinjo china, zimakhala zosavuta. Kuthamanga kwa mpweya kumeneku sikungokankhira gasi mumadzimadzi, komanso amakankhira madzi mu gasi. Pamenepo, imagwiranso ntchito kukakamiza. Mwa njira iyi, kusakanikirana kwa magawo awiri kudzakhala mofulumira, ogwira ntchito, yunifolomu, ndi kukhala ndi thovu labwino, zomwe zimakwaniritsa zofunikira zaukadaulo za thovu.

Cie-China.org ndiye otsogola opangira konkriti wonyezimira omwe amapereka konkriti wotulutsa thovu, superplasticizer,thovu konkire mphamvu zowonjezera kwa wopepuka konkire, Zolemba za CLC. Ngati mukuyang'ana wothandizira thovu, chonde khalani omasuka Lumikizanani nafe.
