Kutulutsa kwamakono kwa makoma kumayimiriridwa ndi "zimphona" zotere za zida zomangira ngati ubweya wa mchere wokhala ndi michere yosiyanasiyana, ndipo mbale zopukutira za polyfoam ndizotalikirana. Zosankha zonsezi ndi zida zabwino kwambiri kuti zithandizire makhoma. Koma pali kusowa kwa iwo, ndizokwera mtengo, ndipo kuyika kwawo kunali kovuta, kaya mlanduwo ndi chithovu cha kusokonezeka kwa makoma, ili ndi mawonekedwe osazindikirika komanso nthawi yophweka, Ndipo mtengo wake ndiwokwera kwambiri.
Zachidziwikire, mtengo wa chithovu pawokha ungalumikizidwe ndi kufunika kogwiritsa ntchito makina owombera omwe akufunika kugwiritsidwa ntchito pogwira ntchito ndi madera akuluakulu a pamwamba omwe amathandizidwa. Koma, ngakhale poganizira izi, mtengo wake umasainidwa, koma ubwino wogwiritsira ntchito mitundu iyi yamafuta.
Kuphatikiza pa kuthekera kogwiritsa ntchito, kutchingira ndi chithovu kumakhala ndi zabwino zambiri, zomwe zimadziwika ndi mtundu uliwonse wa kutsimikizira. Tiyeni tiziyendayenda pa aliyense wa iwo, ndikupeza chomwe chithowa ndi chithovu cha makoma.
Mitundu ya chithovu ndi maubwino ake
Ubwino wogawana mtundu uliwonse wa chithovu:
- Kutupa kwamitundu nthawi zina kumakhala kochulukirapo kuposa zisonyezo za ubweya ndi chithovu, zomwezo zimagwiranso ntchito pazosangalatsa;
- Chiwindi chimamatira ku zinthu zilizonse "zolimba", mawonekedwe ake ndi zinthu zake zilibe kanthu, kupatulanso kupatula polyethylene;
- Izi zili pafupi zamuyaya. Ndi ukadaulo wogwiritsa ntchito, zaka zambiri zitha kutumikira popanda kufunika kuti zisinthe;
- Ecology. Pambuyo polimba, zinthuzo sizingagawire chilichonse chovulaza mlengalenga chomwe chitha kuvulaza thanzi la anthu;
- Amateteza chitsulo ku masidation, chifukwa chosindikizira kwathunthu;
- Ngati mumagwiritsa ntchito ziphuphu pamatabwa, adzaziteteza ku zopezeka m'mafanga ndipo kupewa kuvunda;
- Itha kugwiritsidwa ntchito ndikugwiritsidwa ntchito ndi kutentha kwambiri komanso kutentha kwambiri.
Ndi mapindu omwe adagwirizana, koma sizingakhale kuti palibe cholakwika? Uko nkulondola, singathe. Inemwini, kungosowa kwa thovu latsoka kumabwera m'maganizo, izi ndizovuta kulolera ultraviolet. Mothandizidwa ndi zinthu zake, choyamba chimasintha utoto ku chikasu mpaka lalanje lowala, kenako ndikuwonongedwa kwathunthu. Pofuna kupewa, zinthuzo ziyenera kukhala kutali ndi kuwala kwa dzuwa.
Nkhani pamutu: tepi yokongoletsa yofukiza: Momwe mungasoke
Komanso, kusokonezeka pambuyo poti kukhazikika kumayenera kukhala otetezedwa ku chinyezi kuti chisalowe, pomwe chithovu chake chimatenga bwino. M'mawu, chithovu sichitha kusasiyidwa, limafunikira zowonjezera zowonjezera.
Malinga ndi kapangidwe ka thovu, ndi imodzi ndi ziwiri komanso ziwiri ndikugawika m'mitundu itatu yayikulu:
- Msonkhano;
- Foamizole;
- Polyurethane.
Kukweza
Kutulutsa makoma ndi chithovu cha msonkhano kumapangidwa m'malo ang'onoang'ono, chifukwa ndizopanda phindu kugwiritsa ntchito m'malo akulu. Zonse chifukwa chithovu chonyamula chimagulitsidwa pamlingo wochepa mu cylinders a 200, 350 ndi 750 ml. Mmodzi wa balloon wamkulu kwambiri ndi wotsika mtengo kwambiri, koma amangogwira pa 1 mita. m. Malo ophatikizika, operekedwa ngati makulidwe ali mpaka 8 centimeters.
Khoma lokhala ndi chithovu chokwera pamanja limakhala ndi zotupa zotsika kwambiri kuposa kugwiritsa ntchito foamuzole ndi chithovu cha polyirethane, pomwe chisudzo cha polyurethachi chimatha kudzitamandira 90%.
Kuvulala kwa chithotho chonyamulamo kumachitika chifukwa cha kupezeka kwake pansi pomwe kumakhala kovuta, komanso chifukwa cha zomwe zimachitika ndi chinyezi, chomwe chimapezeka mlengalenga. Ikani chithovu chokwera makamaka kuti chisindikizo, malo otsetsereka pazenera komanso pokhazikitsa zitseko za pulasitiki. Chotupa chimathanso kukhazikitsidwa, koma pokhapokha malowo ndi ochepa, mwachitsanzo, pa khonde kapena loggia.
Pulayala
Izi zikuchitika kale chifukwa chomenyera thovu. Kupezeka, osamvetseka mokwanira, mu mawonekedwe a mbale, komanso chithovu chokhazikika, koma sichoncho. Munthawi yamadzimadzi, izi zatulutsidwa kale patsamba lomwe ntchito imachitika. Izi zimachitika pogwiritsa ntchito galimoto yapadera, yomwe mkati mwa kupanikizika imasungunuka ndikupanga ndi utomoni.
Kutulutsa kwa foamuzol kumapangidwa ndikugwiritsa ntchito pamwamba ndi mfuti yomanga. Chiwopsezo chimachitika kale mkati mwagalimoto, mutatha kutsatira khoma ndikuwumitsa kwa mphindi 15, chisanu chonse chimachitika masiku awiri kapena atatu. Izi zimapuma mwachangu ngati malowo sanaphatikizidwemo.
Nkhani pamutu: Kusamba Kusamba: Zimawononga ndalama zingati?
Chifukwa cha kuwuma kwakutali, kumagwiritsidwa ntchito makamaka kusokonekera kwa nsapatozo, ndikupanga kutentha kwa kutentha komwe kumadzaza mafomu apadera. Kutchinga kwa khoma ndikugwiritsidwa ntchito kwambiri m'malo antchito.
Kuphatikizidwa kwa thovu la matenthedwewa kumaphatikizapo ma carbamides ndi ammaldehydes. Chifukwa cha izi, ambiri amakhulupirira kuti nkhaniyi imadziwika ndi zinthu zovulaza pambuyo pozizira. Ndikulengeza moyenera, izi sizili choncho, nyumbayi ya malingaliro awa amtunduwu m'chiwombalo amayimitsidwa kwathunthu ndipo samawopseza thanzi la anthu.
Polyirethan
Polyurethane thovu la khoma ndi zinthu zokutira zamafuta za akatswiri. Popeza ndi gawo limodzi ndipo lili ndi isocIonate ndi polyl. Chiwopsezo chimachitika chifukwa cha zomwe zidalipo. Khomalo musanayambe kugwiritsa ntchito nkhuni zopukutira zomwe sizikufuna kukonzekera, mumafunikira kuti muchepetse kuchuluka kwa chithovu chogwiritsidwa ntchito.
Ndiosavuta kuchita ngati mungagwiritse ntchito yomanga yapadera ndi makina omwe mumapanikizika adzaperekedwa kwa njira yomalizidwa pakhoma. Pambuyo polemba, polsurethane amazizira pakangopita mphindi zochepa, ndipo ngakhale nthawi 120, kudzaza malo onse, ngakhale m'malo ovuta kwambiri. Chikumbutso cha Data chimakhala chothandiza kugwiritsa ntchito madera akulu chifukwa cha kuchuluka kwakukulitsa ndikudzaza.
Mukamagwira ntchito ndi makoma akulu, musamalire kuti kugwiritsa ntchito thovu la polyeline, pankhaniyi kumatsatira zigawo zingapo. Ngati muchita zonse mu gawo limodzi, chithovu chimatha kukhala chosagwirizana, ndipo chifukwa cha zovuta zambiri zimatha kuphwanya kapangidwe kake ka kapangidwe kake, mwachitsanzo, chimango.
Kudzaza chithotho - malangizo
Mokulira, gwiritsani ntchito makoma a thovu kuchokera mkati ndikosavuta, koma pali nthawi zambiri. Choyamba, izi ndi chitetezo cha ntchito. Zomwe mtundu wa chithovu sukutulutsa, muyenera kutsekedwa mu suti yoteteza kuchokera ku polyethylene, chifukwa ndi izi, chithovu sichimayenda.

Zovala ziyenera kukhala ndi hoodi, chifukwa, ngati njira yothetsera igwere kulowa tsitsi, iyenera kudulidwa. Kuphatikizanso magolovu, magalasi ndi kupuma, kuteteza manja, maso ndi kupuma thirakiti, motsatana.
Kupumulirako kumafunikira, chifukwa pakukula ndi kumasula chithovu, mpweya umadziwika, womwe suyenera kupuma ngati simukufuna kukhala ndi mavuto azaumoyo, kuwonjezera apo, tinthu tating'onoting'ono tidzakhalapo mumlengalenga.
Mfundo yachiwiri ikugwirizana ndi njira yogwiritsira ntchito thovu pakati pa malire a malo otetezedwa, amatha kukhala makhoma awiri ndi chimango chapadera chomwe chimalekanitsa khomalo ndi malo. Njira ndi ziwiri, mothandizidwa ndi pistol yomanga ndi kupopera mphamvu. Njira yachiwiri, monga momwe mukuganizira kuti kugwiritsa ntchito chithovu chokwera.
Mukamagwiritsa ntchito pisiti yomanga, muyenera kulipira zosemphana ndi chithovu, polyirethane kapena thovu, ndikuyika yunifolomu ya pakhoma. Khomalo limasokonekera, ziyenera kukhala pansi kuchokera pansi, zidzakhala zosavuta kuzimitsa kutha kwa malo. Malinga ndi zotsatira zake, khoma liyenera kupanga mtundu wa chovala cha thovu ndi malo ochepa oponyedwa.
Kugwira ntchito ndi thovu lokweramo, muyenera kukumbukira kuti silinda iyenera kusungira pansi osaloleza madigiri awo, apo ayi kuti kuphulika kwake ndikotheka, sikungathe kukutetezani suti yoteteza.
Nthawi yachitatu imadetsa nkhawa za kuchuluka kwa wosanjikiza. Ngati kukula kwamphamvu kumapitilira 8 cm mu makulidwe, kugwiritsa ntchito kwake kuyenera kugawidwa m'magawo. Gawolo lililonse la chithovu liyenera kuwuma kwathunthu lisanagwiritsidwe. Nthawi zambiri, kutentha kwathunthu chithovu mumafunikira mpaka maola 24.
Monga tanena kale, thovu liyenera kuyikidwa m'magawo angapo, chifukwa chakuti kukakamiza komwe kumachitika chifukwa cha kutukuka kwa kukula kungathetse nkhuni, ngakhale atapangidwa ndi mbiri ya aluminium.
Kanema "polyirethan. Kupopera mbewu ndikudzaza »
Kanemayo akuwonetsa momveka bwino za chithovu cha polyurethane akagwiritsidwa ntchito pamtunda. Itha kuwoneka ndi wamaliseche, pomwe imakula ndikudzaza malo onse ofunikira.
