Zigawo zikuluzikulu za matope a ufa

Matope a ufa wa ufa ndi matope omaliza opangidwa ndi zinthu zopangira mufakitale kudzera mu machenjere molondola komanso yunifolomu. Itha kugwiritsidwa ntchito pokhapokha powonjezera madzi ndikusunthira ku malo omanga. Chifukwa cha matope owuma a ufa, imagwiritsidwa ntchito kwambiri. Chimodzi mwazinthu zazikulu kwambiri ndikuti mawonekedwe ake owonda amatenga gawo lokhazikika, kukongoletsa, kuteteza ndi kutumphuka. Mwachitsanzo, matope okhala ndi kulumikizana kwakukulu makamaka amaphatikizapo matongete matope, matope a khoma ndi matailosi pansi, kuloza matope, kuphika matope, etc.; Matope ndi zotsatira zazikulu zokongoletsera makamaka zimaphatikizapo matope opangira zopondaponda, putty la makhoma amkati ndi ochokera kunja, ndi mavata okongola. etc.; Matope a madzi, matope osiyanasiyana omwe amagogoda, odzimanga okha, omwe amangokhala ndi matope, kukonza matope, matope, etc. amagwiritsidwa ntchito kutetezedwa. Chifukwa chake, kapangidwe kake kamavuta, ndipo nthawi zambiri kumapangidwa ndi zinthu za simenti, zofanizira, michere, kuphatikiza mafuta, utoto, kuphatikizika ndi zinthu zina.

1.
Zida zomwe zimagwiritsidwa ntchito poyendetsa matope owuma ndi: simenti ya ku Portland, simenti ya alumina, calcium silmy, laimu, silika. Simenti ya Portland (nthawi zambiri imayimira i) kapena sime yoyera ya Portland ndiye zikuluzikulu zazikulu. Masamba ena apadera nthawi zambiri amafunikira matope. Kuchuluka kwa maakaunti a binaer kwa 20% ~ 40% ya malo owuma.

2. Filler
Ogwiritsa ntchito mafinya akuluakulu a ufa ndi: mchenga wachikasu, mchenga wa quartz, ma dolomite, owuma, ndikuwuma, sing'anga, sing'anga. Kukula kwa tinthu ndi: kuzungulira kwa 4mm-2mm, sing'anga filler 2mm-0.1mm, ndi filler wabwino kwambiri pansipa 0.1mm. Pazinthu zokhala ndi tinthu tating'onoting'ono kwambiri, mwala wabwino wamiyala ndikusakaniza miyala yamtengo wapatali iyenera kugwiritsidwa ntchito ngati okalamba. Matalala wamba a ufa sangagwiritsidwe ntchito osati kokha kuphwanyidwa mwalawo, komanso zouma komanso mchenga ngati kuphatikizika. Ngati mchenga ndiwokwanira kugwiritsidwa ntchito konkire yolimba kwambiri, iyenera kuthana ndi zomwe zimapangitsa kuti zisambidwe. Chinsinsi chopanga matope a ufa ndi mkhalidwe wodalirika umakhala mu gawo la tinthu tating'onoting'ono tambiri ndi kulondola kwa chiwerengero chokwanira, chomwe chimadziwika mu mzere wa matope owuma.

3. Ma Almixtive
Makina a mgonero wa michere wa matope a ufa ndi: zopangidwa ndi mafakitale, zinyalala za mafakitale, zophuka zamagetsi, zophuka za mapiri, zimakhala ndi silicon yokhala ndi calcium oxide. Aluminiyamu hydrochloride ali ndi ntchito yayikulu komanso hydraulic kuuma.

4..
Kusakaniza ndi kulumikizana kwa matope owuma, mtundu ndi kuchuluka kwa kuphatikizika ndi kusinthasintha pakati pa ma admixtimes ndizogwirizana ndi matope a ufa wa ufa. Kuti muwonjezere kugwirira ntchito komanso kugwirira ntchito matope a ufa wa ufa, kuchepetsa kusokonekera kwa matope, kuchepetsa matope osavuta kutuluka ndi matope opangira ufa ndikuchepetsa mtengo wake. Monga polymer pa mphira wa mphira, fibershi ya nkhuni, hydroxymethyl cellulose ether, hydroxypropyl celly cember, pva fiber ndi madzi ochepetsa madzi.
