Chitsulo CHIKWANGWANI pulasitiki mkulu-mphamvu

Kusakaniza kumagawidwa mu makina osakanikirana ndi kusakaniza kwamanja.Pakali pano, okakamiza kapena osakaniza matope amagwiritsidwa ntchito m'makampani kusakaniza zipangizo, ndipo kusakaniza kwamanja sikugwiritsidwa ntchito Zida ndi zida: okakamiza kapena osakaniza matope, ndowa, masikelo, vibrator, mafosholo, trolleys, etc.

Kugwiritsa ntchito madzi pomanga kumatengera momwe madzi amagwiritsidwira ntchito papepala loyang'anira mtundu wa zinthu, ndipo amatsatiridwa mosamalitsa motsatira miyezo kuti akwaniritse muyeso wolondola.

Kusakaniza: Sakanizani zouma kaye kenako nyowa.Ikani zinthu zambiri mu chosakanizira ndikuwumitsa kwa mphindi 1-3 motengera thumba lalikulu kaye kenako thumba laling'ono kuti likhale losakanikirana.Kulemera kwa kusakaniza kulikonse kumatsimikiziridwa molingana ndi makina ndi zomangamanga;molingana ndi kulemera kwa zinthuzo, madzi ofunikira pakusakaniza kulikonse amayezedwa molondola malinga ndi momwe amamwa madzi, amawonjezeredwa kuzinthu zowuma zosakanikirana, ndikugwedezeka kwathunthu.Nthawi si osachepera 3min, kotero kuti ali ndi madzimadzi abwino, ndiyeno zinthu akhoza kutulutsidwa kwa kuthira.

Zinthu zothira zisanapangidwe, ndikofunikira kuyang'ana ngati anangula ali owotcherera mwamphamvu, ndipo misomali yosamva kutentha iyenera kukhomeredwa pazigawo zopitilira 500C.Pamwamba pa nangula ayenera kupakidwa utoto ndi 0. 5-1mm wandiweyani utoto kapena wokutidwa ndi tepi ya pulasitiki kuti ateteze mphamvu yokulitsa mukatha kutentha ndikuchotsa zinyalala mu nkhungu.

Chosakaniza chatsopanocho chiyenera kuthiridwa mwamsanga, nthawi zambiri mkati mwa 20min.Thirani zosakaniza zosakanikirana mu nkhungu, ndikuyika vibrator mu vibrator mu nthawi, ndipo vibrator iyenera kukhala yofanana.Pamene pamwamba pa castable ndi slurried, thovu ndi kumasulidwa.Pamwamba pawokha, ndodo yogwedezeka imasunthidwa, ndipo liwiro loyenda ndi 1-2m / min.Ndodo yogwedezeka ikatulutsidwa, liwiro limachedwa.

Kulimbitsa kusanamalizidwe mutatha kuthira, kutentha kwa malo kuyenera kusungidwa pamwamba pa 10C (10-30.C).Ngati kutentha kwa malowo kuli kotsika kuposa 0'C, njira zofananira zotenthetsera ndi kuteteza kutentha ziyenera kuchitidwa, apo ayi zingayambitse kuchedwa ndikupangitsa kuti zinthu ziwonongeke.

Zida zazikulu zomwe zimagwiritsidwa ntchito ndi filimu ya pulasitiki ya polyethylene, matumba a udzu, ndi zina zotero. Zofunika kutentha ndi kuwongolera: Kutentha kwa thupi loponyedwa kumakhala pakati pa 15-35C Ngati kutentha kumapitirira kutentha kumeneku, kutentha kofanana kapena kuziziritsa kuyenera kuchitidwa, apo ayi. ntchito ya mankhwala idzachepetsedwa.

Pambuyo castable ali owumitsidwa, m`pofunika yomweyo kuphimba pamwamba pa zomangamanga thupi ndi polyethylene pulasitiki filimu, ndi thercover ndi chonyowa udzu thumba kuteteza madzi nthunzi ndi kulimbikitsa kutsegula simenti Pambuyo kuumitsa, ndikoletsedwa kumenya ndi vibratewithin mmodzi. tsiku.Malinga ndi kuuma kwake, imatha kugwetsedwa pambuyo pa maola 24-30 akuwumitsa.

Pambuyo pobowola, iyenera kusungidwa kwa masiku awiri ngati pakufunika, ndipo filimu ya pulasitiki ya polyethylene ndi matumba a udzu wonyowa ayenera kuwonjezeredwa panthawi yokonza.Pambuyo masiku atatu akuchiritsa, chotsani filimu ya pulasitiki ndi thumba la udzu.Lolani thupi lolimba kuti liume mwachibadwa mumlengalenga kwa tsiku limodzi musanaphike.

Kuphika ndi njira yomaliza yolumikizira zinthu zotayidwa.Popeza kuti thupi loponyera limakhala lowuma kwambiri, ndiloletsedwa kuti liwotche mofulumira kwambiri panthawi yophika, mwinamwake lingayambitse ngozi yosweka.
