Mayankho odziwika bwino omangira pansi pa malo oimika magalimoto pansi pa nthaka

Pa malo oimika magalimoto pansi pa nthaka, njira zodziwika bwino zoimika pansi zimaphatikizapo: pansi ya epoxy, pansi yolimba komanso pansi yolimba.

Pansi pa epoxy: pansi pa epoxy ya garaja

Pansi pa epoxy, ndiko kuti, utoto wa pansi wa epoxy resin ngati chinthu chachikulu, ndi mchenga/ufa wa quartz ngati zinthu zothandizira, pogwiritsa ntchito kupukuta, kupukuta, kukanda, kupukuta kapena kupopera ndi njira zina zomangira, kuti pansi pakhale pamwamba. Pambuyo pomanga pansi, gawo la epoxy limaphimba konkire ya simenti ya udzu, motero limalekanitsa konkire ya udzu ku mavuto omwe angakhalepo monga mchenga, fumbi ndi zina zotero. Pansi pa epoxy, palibe fumbi, silitha kusweka, losavuta kuyeretsa, mtundu wowala.

Mayankho a pansi pa epoxy omwe amagwiritsidwa ntchito kwambiri poika magalimoto ndi awa: pansi pa epoxy yamtundu wa mortar, pansi pa epoxy yopyapyala, pansi pa epoxy yamtundu wodziyimira pawokha.

Pansi pa epoxy yamtundu wa matope, njira yake nthawi zambiri imakhala: kupukutira ndi kuyeretsa pansi, choyambira chimodzi cha epoxy, matope awiri a epoxy, putty awiri a epoxy, zokutira ziwiri za epoxy pamwamba. Makulidwe ake ndi pakati pa 0.8-1.5mm.

Pansi pa epoxy, njira yake nthawi zambiri imakhala: kupukuta ndi kuyeretsa pansi, epoxy primer imodzi, epoxy mortar imodzi, epoxy putty imodzi, epoxy surface covering imodzi. Makulidwe ake ndi pakati pa 0.5-0.8mm.

Pansi pa epoxy yodziyimira payokha, njira yake nthawi zambiri imakhala: kupukuta ndi kuyeretsa pansi, pulasitala imodzi ya epoxy, matope awiri a epoxy, epoxy putty imodzi, ndi epoxy flow plane plane covering imodzi. Makulidwe ake ndi pakati pa 2-3mm.

Pansi pa epoxy yopyapyala, pansi pa maziko okha ndi yopyapyala kwambiri, mphamvu ya konkire ndi yabwino kwambiri, ndipo bajeti ya ndalama ndi yochepa kwambiri, zotsatira zooneka za zofunikira za bokosilo sizikhala zapamwamba, nthawi zambiri sizikulimbikitsidwa. Pansi pa epoxy yopyapyala, poyerekeza ndi pansi pa epoxy yopyapyala, pamwamba pake ndi yopyapyala, yofewa, yolimba, yokana kugunda ndi yolimba, ndiye pulogalamu ya pansi pa malo oimika magalimoto a epoxy. Pansi pa epoxy yodziyimira payokha imagwiritsidwa ntchito m'mabungwe aboma, malo ochitira Olimpiki ndi mapulojekiti ena adziko lonse lapansi pamapaki a magalimoto apansi panthaka. Kuphatikiza apo, mapulojekiti a munthu payekha, ngati sakutsatira kusalala kwa pamwamba ndi zotsatira za kumva, kungothetsa simenti pamwamba pa konkire ya mchenga, fumbi, pali ma primer awiri a epoxy, awiri a epoxy pamwamba pa pulogalamu yosavuta ya pansi pa epoxy.

Chifukwa chake, chinthu chofunikira kwambiri posankha mtundu wa pulogalamu ya epoxy pansi, choyamba, maziko a pansi, kachiwiri, mtundu wa zotsatira zomwe zikufunika kuti zitheke, kenako bajeti ya ndalama. Pakati pa zitatuzi pali zomveka bwino komanso zogwirizana.

Pansi yosagwira ntchito

Zipangizo zapansi zosatha kutha kugwiritsa ntchito simenti, zopangidwa ndi simenti yapadera, zinthu zosatha kutha (mchenga wa quartz, emery, tin-titanium alloy, ndi zina zotero) ndi zowonjezera ndi zinthu zina, kuti zigwiritsidwe ntchito bwino pogwiritsa ntchito njira yosakanikirana ndi fakitale yopangira kuchokera mu thumba, ufa.

Kupanga pansi kosatha kumagwirizana ndi kupanga konkire ya simenti. Pambuyo pokonza bwino, kulinganiza ndi kugwedezeka kwa konkire ya simenti pamwamba pa malo oimika magalimoto apansi panthaka, zinthu zosatha pansi zidzafalikira pamwamba pa siteji yoyamba yolimba, ndipo zinthu zosatha zidzapangidwa zonse ndi konkire ya simenti kudzera mu chida chapadera chomangira pansi, makina osalala, kuti apange gawo loteteza pamwamba pa konkire ya simenti.

Monga tonse tikudziwira, konkireti ya simenti ya pansi pa nthaka ya C20, C25 standard, C25, mwachitsanzo, mphamvu yopondereza pamwamba ya pafupifupi 25MPA. Koma pambuyo pomanga pansi yosatha, mphamvu yopondereza pamwamba imatha kufika 80MPA, kapena kupitirira 100MPA, ndipo mphamvu zina zopindika, mphamvu yosatha ndi zizindikiro zina zasintha kwambiri.

Chifukwa chakuti pansi yosatha ndi ya zinthu zopangidwa ndi simenti, ikhoza kuphatikizidwa bwino ndi simenti ya simenti, bola ngati simenti ya udzu sinasweke, pansi yosatha kwa zaka zambiri popanda kusweka, popanda kutayika. Nthawi yomweyo, mtundu wake si wokongola komanso wolemera ngati pansi ya epoxy, yomwe nthawi zambiri imakhala imvi, yobiriwira, yofiira ndi mitundu ina yoyambira.

Konkire wamba wa simenti, chifukwa cha kupanga ndi kumanga kosayenera, kapena kusokonekera kwa zaka zambiri, n'zosavuta kutembenuza mchenga, fumbi, kutanthauza kuti, konkire wa simenti m'malo olekanitsidwa a mchenga, miyala ndi simenti. Mtundu uwu wa malo oimika magalimoto pansi, kuyeretsa zachilengedwe kumakhala kovuta kwambiri, pamwamba pa magalimoto oimika magalimotowo pali fumbi, mwiniwake amadandaula kwambiri. Pansi losawonongeka ndi njira yotsika mtengo komanso yothandiza yothetsera vutoli. Pansi silikuwonekanso ngati fumbi ndi mchenga, ndipo chifukwa cha kupukutira ndi kukangana kwa galimotoyo, nthaka yosawonongeka idzakhala yowala kwambiri.

Pansi pa malo oimika magalimoto pansi pa nthaka, pansi pa nthaka, pali mchenga wa quartz, ndipo pansi pa diamondi pali mtundu wa simenti kapena imvi.

kuuma pansi penetrant

Pansi pa garaja pali konkiredi, pansi pa mchenga, pansi pa terrazzo, ndi zina zotero, ngati garaja yathiridwa konkiredi ndi nthaka yokonzedwa kalendala, tikulimbikitsidwa kuchita mwachindunji pansi pa Yade, kapangidwe kake ndikosavuta, zizindikiro zaukadaulo ndi pansi pa garaja zimakhala zofanana ndi kukonza pambuyo pake ndikosavuta kwambiri, komwe kulinso ubwino wa pansi pa garaja. Pansi pa Yade cholinga choyamba cha chitukuko cha pansi pa penetrant, ndikupeza malo olowa m'malo mwa epoxy, komanso pansi pa garaja, ubwino wolimba wolimba wolimba, pansi pa penetrant pambuyo pa kumangidwa kwa utoto siwofanana ndi pansi pa epoxy ngati wamitundu yosiyanasiyana, koma kusiyana si kwakukulu, kusiyana pakati pa ziwirizi kuli mu makulidwe a pansi pa epoxy ndi makulidwe enaake, pambuyo pomanga nyumba yoyipa, zimakhala zosavuta kuchotsa khungu, ndipo kukonzanso ndi kukonza mochedwa kumakhala kovuta kwambiri, ndipo ntchito ya makina a pansi pa Yade. Njira yolowera pansi yolowera pansi ndi yolowera pansi pa konkire, ndipo imachitapo kanthu ndi konkire, ndipo potsiriza imapangitsa kuti pamwamba pakhale mawonekedwe otsekedwa, osati kokha kuthetsa kusanja kwa konkire ndi imvi zomwe zimachitika nthawi yomweyo zimathanso kuwonjezera kuuma kwa pamwamba pa konkire, ndipo nthawi yomweyo pa yankho la asidi ndi alkali limagwira ntchito inayake yokha, eni nyumba ambiri pamsika amagwiritsa ntchito pansi yolowera pansi ngati pansi yoyamba ya garaja.
