1. Purty imagwiritsidwa ntchito ngati chinthu chopangira chokongoletsera pamwamba kuti chiziphikidwe pa zomangamanga
Puti ndi loonda laling'ono lakunsi kwa matope. Mateni amakoka pamtunda wamagawo osalala (monga matope, gulu la gypsum, etc.) kupangitsa fumbi lakunja losalala komanso losavuta kukhala ndi madera omwe ali nalo kuwonongeka kwakukulu kwa mpweya). Mateni amatha kugawidwa mu malo opangira (phala amapaka mafuta owuma) ndi ufa wowuma ufa) ndi malo owuma awiri (opangidwa ndi ufa wa putty) Malinga ndi mawonekedwe omaliza. Ndi chidwi cha anthu ku ukadaulo womanga za zoukira za zomangamanga, puteke monga zinthu zofunika kwambiri zakonzedwanso. Opanga osiyanasiyana apanyumba adayamba kupanga dete ndi zolinga zosiyanasiyana komanso mitundu yosiyanasiyana, monga ufa, maste putty, khoma lakunja, loyera, etch.
Poona kuti mwagwiritsa ntchito zolankhula zapakhomo, nthawi zambiri pamakhala zovuta monga kumenyedwa ndi kusambira, zomwe zimakhudza chitetezocho ndi zokongoletsera zokongoletsera zokutira pa nyumba. Pali zifukwa ziwiri zazikulu zowonongeka za filimu yokutira:
Limodzi ndi mtundu wa utoto;
Lachiwiri ndilabwino kwa gawo lapansi.
Zochita zawonetsa kuti zoposa 70% ya zofooka zokutira zimakhudzana ndi kusamalira gawo lapansi. Matekitala a zofukitsira za zomangamanga amagwiritsidwa ntchito kwambiri ngati zopangira kuti ziziphika. Sizingangosalala ndikukonzanso mawonekedwe ndi nyumba, komanso kukhazikika kwambiri kumatha kukulitsa chitetezo ndi magwiridwe okongoletsera zokutira pamanja. Kuthana ndi moyo wautumiki ndi chinthu chofunikira kwambiri chothandizira kwambiri zopangira zomangira zopangira zopangira, makamaka khoma lakunja. Mafuta owuma amodzi ali ndi phindu lazachuma, zaukadaulo komanso chilengedwe pakupanga, mayendedwe, kusungirako, kumanga ndi zina zotero.
Chidziwitso: Chifukwa cha zinthu monga zopangira ndi mtengo, sungunuka ufa wa polider umagwiritsidwa ntchito mu ufa wotsutsa makoma akunja, komanso amagwiritsidwanso ntchito pakhoma lalikulu.
2. Udindo wa anti-bracking makoma a kunja
Tsamba lakunja limagwiritsa ntchito simenti ngati chinthu cholumikizira, ndipo mapira ochepa amatha kuwonjezeredwa kuti akwaniritse zotsatira za synergist. Udindo wa Demict-Wozimitsa Mapati Otsutsa Makoma Akunja:
Ma protter otsekera pamtunda amapereka maziko abwino, omwe amachepetsa kuchuluka kwa utoto ndikuchepetsa mtengo wa polojekiti;
Matenthedwe ali ndi kutsatira kwambiri ndipo amatha kuphatikizidwa ndi khoma lapansi;
Imakhala ndi mphamvu inayake, imatha kusokoneza mphamvu yakukula kosiyanasiyana ndi kuphatikizira zigawo zosiyanasiyana, ndipo zimakhala ndi kukana kwabwino;
Mateke ali ndi nyengo yabwino, kuwonongeka, kukana chinyontho komanso nthawi yayitali yautumiki;
Zachilengedwe pachilengedwe, osati poizoni komanso otetezeka;
Pambuyo kusintha kwa zowonjezera zowonjezera, monga ufa wa rateni ndi zida zina, makoma apanja amathanso kukhala ndi zabwino zotsatirazi:
Ntchito yokoka mwachindunji pamapeto okalamba (penti, matayala, zashic ndi makoma ena osalala);
Thixotropy, mawonekedwe osalala amatha kupezeka mwa kungotuluka, ndikutayika chifukwa chogwiritsidwa ntchito ndi zitsulo zambiri chifukwa cha maziko osakhazikika amachepetsedwa;
Ndi zotanuka, zitha kupewa ming'alu yamaliro, ndipo imatha kuthetsa kupsinjika kwa kutentha;
Madzi abwino mosangalala komanso madzi.
3. Udindo wa Masamba Osinthidwa Pochedwa
.
Sinthani kugwirira ntchito komanso kusintha magwiridwe antchito a batty;
kusungidwa kwamadzi ena;
kuchuluka kwa kugwirira ntchito;
Pewani kusokoneza.
.
Chepetsani solucic modulus ya punty ndikuwonjezera zofananira ndi maziko osanjikiza;
Sinthani kapangidwe ka simenti ya micro-micro-micro, zimawonjezera kusinthana mutawonjezera ufa wa punty, ndikupewa kusweka;
Sinthani ufa kukana;
Hydrophobic kapena kuchepetsa mayamwidwe amadzi a punty wosanjikiza;
Onjezerani cholumikizira cha putty khoma lam'munsi.
Chachinayi, Zofunikira za Khoma lakunja
Njira yomanga yomanga iyenera kulabadira:
1. Mphamvu zomanga:
Mphamvu zomangamanga makamaka kutentha ndi chinyezi cha chilengedwe. M'masiku otentha, maziko a maziko ayenera kupopera mbewu mankhwalawa ndi madzi, kapena kunyowa, kutengera magwiridwe antchito apatsa. Popeza khoma lakunja limagwiritsa ntchito simenti ngati simenti yowoneka bwino, kutentha kozungulira sikuyenera kukhala kotsika kuposa madigiri 5, ndipo sikudzaundana musanayambe kulimba.
2. Kukonzekera ndi kusamala musanakwapula pake:
Akufunika kuti ntchito yayikulu yatsirizidwa, ndipo nyumbayo ndi padenga zamalizidwa;
Magawo onse ophatikizika, zitseko, mawindo ndi mapaipi a phulusa liyenera kukhazikitsidwa;
Pofuna kupewa kuipitsidwa ndi kuwonongeka kwa zinthu zomaliza mu batch pokonza, zinthu zina zotetezedwa ziyenera kutsimikiziridwa pamaso pa kubowola, ndipo zigawo zoyenera ziyenera kuphimbidwa ndi kuphimbidwa;
Kukhazikitsa kwazenera kuyenera kuchitika pambuyo pa chingwe cha putty.
3. Chithandizo cha Pamaso:
Pamwamba pa gawo lapansi liyenera kukhala lolimba, lathyathyathya, louma, loyera, lopanda mafuta, batik ndi zinthu zina zotayirira;
Pamwamba pa mapulani atsopanowo ayenera kuchiritsidwa kwa masiku 12 chiwongola dzanja chisanatuluke, ndipo choyambirira chopaka chopondera sichingabwezeretsedwe ndi phala la simenti;
Ngati khomalo limakhala louma musanamangire, khoma liyenera kunyowetsedwa pasadakhale.
4. Njira Yogwiritsira Ntchito:
Thirani madzi oyenera mu chidebe, ndiye onjezerani ufa wowuma, kenako nkusasunthika ndi chosakanizira mpaka ndi yunifolomu popanda ufa wopanda mafuta.
Gwiritsani ntchito chida chokwawa cha batch, ndipo kuwongolera kwachiwiri kwa batch kumatha kuchitika pambuyo pa batch woyamba kumalizidwa pafupifupi maola 4;
Scrape Wosambitsa bwino, ndikuwongolera makulidwe kukhala pafupi 1.5mm;
Mateyo opangidwa ndi simenti amatha kupaka utoto wa alkali-polimba pokhapokha mutamalizidwa mpaka kuchepa komanso nyongayo.
5. Zolemba:
Kufuula ndi kufinya kwa gawo lapansi liyenera kutsimikiza;
Matope osakanikirana ayenera kugwiritsidwa ntchito mkati mwa 1 ~ 2h (kutengera fomulayo);
Osasakaniza matope omwe adutsa nthawi yogwiritsa ntchito ndi madzi musanagwiritse ntchito;
Iyenera kupukutidwa mkati mwa 1 ~ 2d;
Pamene maziko am'mbuyo amadabwitsidwa ndi matope a simenti, tikulimbikitsidwa kugwiritsa ntchito mankhwala othandizira kapena mawonekedwe a mawonekedwe ndi zotanuka.
Mlingo waKubwezeretsedwa Polimer Polyderimatha kutanthauza deta ya mankhwala munjira ya kunja kwa khoma la putty ufa. Ndikulimbikitsidwa kuti makasitomala amayendetsa zoyeserera zazing'ono zingapo zisanachitike zisanthu zisanachitike kuti awonetsetse mtundu wa ufa.
