Zoletsa kuwuma zina mu mowa slurry ndi njira ya ntchito

M'munsi kutentha zochepa mofulumira oipa konkire. Madzi amaundana pa zinthu zimenezi, ndi hydration wa binder ndi inaimitsidwa.

kufunika kokhala

Pakuti simenti, njira oterewa ndi osafunika chifukwa iwo m'mavuto mphamvu. Motero, dongosolo amakhala lotayirira, ndi kukana ake ozizira ndi osauka. Pofuna akuchiritsa yachibadwa pa otsika kutentha, m'pofunika njira yoyenera zimene zimachititsa madzi mu gawo madzi.

General kufotokoza zoletsa kuwuma zina

Zoletsa kuwuma zowonjezera mu mtondo simenti anawonjezera pa kutentha m'munsi. Iwo ali madzi, sipangakhalenso ndi chikasu kapena kuwala imvi kulocha, ndipo akhoza kukhala colorless kwathunthu. osakaniza ali osalimba mu uthunthu wa makilogalamu 1.4 pa lita. Koma kachigawo Unyinji wa nitrate calcium, izo ranges kuchokera 42 mpaka 45%. makhalidwe amenewa zosiyanasiyana, malingana ndi mtundu wa mankhwala.

Zoletsa kuwuma zina mu slurry wa anawonjezera ngati n'koyenera kuonjezera sayenda wa zikuchokera, amene kwambiri facilitates mapangidwe zinthu structural. Mu zosakaniza awa ali ndi dzimbiri woletsa, zoteteza zolimba mipiringidzo kwa makutidwe ndi okosijeni. Pambuyo pa Kuwonjezera wa anafotokoza zikuchokera matope akupeza mphamvu mu nthawi yochepa, ndi madzi kulimbikira ukuwonjezeka zakuthupi.

Njira ntchito zina pokonza njira

Pamene zina zoletsa kuwuma akuwonjezeka mu slurry, ndi plasticizer ntchito yomweyi, mchenga ndi simenti. Ndi zofunika kuwonjezera anati zikuchokera pamodzi ndi madzi, chifukwa madzi zoletsa kuwuma zikuchokera angathe pang'ono kuchotsa madzi kusakaniza.

zosakaniza onse bwino osokonezeka, imene nthawi muyenera kugwiritsa ntchito chosakanizira konkire. imeneyi ayenera mpaka maola. Mapeto ndi osakaniza homogeneous. Mlingo wa pachilichonse kudzadalira nthawi kuyanjana ndi khalidwe la chosakanizira konkire. Kuchuluka kwa zowonjezera ayenera kukhala wolingana ndi buku lomwe m'kaundula pa ma CD. Nthawi zambiri ndi 0.2% ndi buku la simenti ndi kulemera. Nkofunika kukumbukira kuti ndalamazo limafanana ndi kutentha mtengo zafotokozeredwa malangizo.

Pamene zina zoletsa kuwuma akuwonjezeka mu slurry kunyumba, n'kofunika kuganizira kuti ndi kucheperachepera kutentha buku mankhwala ayenera ziwonjezeke. Nkofunika kuganizira kuti zikuchokera 0,05% limafanana ndi digiri imodzi. mlingo nthawi zafotokozeredwa magalamu. Ngati mtengo uwu imaonekera mu millimeters, kudziwa kuchuluka kwa kulemera kwake zikuchokera ayenera kugawidwa ndi 1,45. Pomaliza, adzatha kutulutsa buku zinafunika, m'kukoma millimeters. Kokha kuyeza chofunika kuchuluka kwa osakaniza ndi kufotokozanso izo mu njira.

Zoletsa kuwuma zowonjezera mu grout, mayankho amene kwakukulukulu zabwino anawonjezera okha pa otsika kutentha kwa zachilengedwe. Ikani zosakaniza izi m'mikhalidwe yosiyana zosavomerezeka. zinthu kandalama ndi mankhwala konkire ayenera moisten masiku awiri, izo chingamulepheretse kuyanika kunja.

kumwa potashi

Potashi ntchito yomanga monga zoletsa kuwuma zowonjezera. Iye imatchedwanso carbonate potassium luso. Kuti zikhoza kugulidwa mu mawonekedwe a crystalline ufa, amene amakhala ndi solubility kwambiri mu madzi. Zimalimbikitsa njira amaundana pa kutentha amene ali ofanana ndi -36,5 madigiri chizindikiro. Potashi amatha kwambiri imathandizira kuumitsa konkire ndi zomatira khalidwe.

Tsatanetsatane wa zikuchokera adzakhala wolingalira ngati pa akuponya pamaso kupeza mphamvu konkire kutentha ndi m'munsimu madigiri -25. Ngati pali kufunika kulimbitsa chisanu kukana konkire, m'pofunika kuwonjezera zina galasi madzi ndi sodium.

Chotero zoletsa kuwuma zina tikuuzidwa mu slurry, kawirikawiri kwa yochepa solidification. Pamene ndondomeko iyi pafupifupi osadalira pa kutentha yozungulira. Potashi amachita monga zina ndale, amene si bwanji oyenerera. Ndi kutsitsa kutentha mlingo wa ukuwonjezeka mankhwala kutuluka. Choncho, ngati kukwezedwa kwa thermometer ndi mu osiyanasiyana madigiri 0 kuti -5, zana makilogalamu a simenti chofunika makilogalamu 5 mpaka 6 a carbonate potaziyamu.

Pa kutentha osiyanasiyana -6 kuti -10 digiri zoletsa kuwuma zowonjezera kuti ntchito kuchuluka kwa kuchokera makilogalamu 6 mpaka 8 pa zana makilogalamu a simenti. Koma pa madigiri -11 kuti -15 potashi mowa kwambiri chifukwa mu osiyanasiyana makilogalamu 8 mpaka 10 pa yofanana chigawo simenti.

Reviews

Malinga ogula zoletsa kuwuma zina mu slurry, ndi nthenda omwe atchulidwa pamwambapa, tikuuzidwa osati kwa yokonza kasakaniza konkire. Mwa zina, iwo akhoza kugwiritsidwa ntchito mu konkire opepuka, kupanga zinthu magalimoto, kuphatikiza pulasitala, komanso mapangidwe m'misewu.

Makampani, zoletsa kuwuma zina amagwiritsidwa ntchito pa ntchito yomanga milatho nyumba zolinga zosiyana, mafuta ndi gasi nsanja, madamu ndi zinthu zina. Kugwiritsa nyimbo awa akhoza kuchepetsa kumanga nthawi, komanso kuchepetsa ndalama mtengo malo chifukwa cha ntchito zomveka ntchito ndi zida. Ndi otchuka kwambiri ogula payekha ndi anaumanga akatswiri.

Pomaliza

Ngati inu ntchito zoletsa kuwuma zina mu slurry wa, Mchere anapanga pamodzi ndi hydration katundu konkire. Isanafike ntchito zinthu ndi cholinga anafotokoza ayenera bwino mbali ndi makhalidwe a zosakaniza zafotokozedwa pamwambapa.
