Phunziroli kwa mapepala khoma

Pasting mapepala khoma mpanda wayamba ndi kukonzekera pamwamba. Iwo limapangidwa zinthu zotsatirazi: ngati n'koyenera (akale khoma) mayikidwe pulasitala osakaniza, anamuvula izo kwa roughness priming Shpatlevanie (ngati chofunika ndi masking gululi chifukwa zolimba zina) mu zigawo ziwiri, yokonza kumadzazidwa sandpaper (kapena diamondi mauna) pambuyo kuyanika ake, ndi phunziroli ❖ kuyanika wa putty (aliyense wosanjikiza), chodetsa kutali kapena mlingo kwa zomata Wallpaper slicing wallpaper ndi chitsanzo kusankha.

Shpatlevanie - sitepe zofunika kukonza makoma kwa papering. Chifukwa ichi, ife munasindikizidwa microcracks, mlingo pamwamba, kupanga izo zidzakhala zosalala. Shpatlevanie anachita mu zigawo zingapo (malingana ndi chikhalidwe cha makoma) ndi kumanga ndi priming aliyense zikulilima. Anamuvula ntchito sandpaper ndi kukula tirigu 80-120. Cheke ndondomeko analimbikitsa liza filler, amene amapereka zabwino zotsatira. Pulasitala makoma pansi mapepala khoma ayenera kukhala bwino, ndi n'kakang'ono ndi mapepala khoma.

Pokonzekera, ife ntchito malaya awiri - pa pulasitala ndi putty.

Primers - pang'ono achikuda kapena bwino akiliriki kapena vodopolimernye pretreatment njira okonzeka zina pamwamba kuwamaliza. Izi ndi zofunika chigawo chimodzi cha ndondomeko ya kulenga pamwamba latsopano wachikulire kapena kubwezeretsedwa. Malinga primers gawo lapansi ndi:

- akiliriki, ntchito zochizira pafupifupi mitundu yonse ya pamalo. Iwo amakumana zofuna ogula si fungo poizoni, wathunthu kuyanika ndi maola awiri mpaka asanu. Ntchito ngati phunziroli kwa mapepala khoma;

- alkyd, ambiri amangoti ntchito ntchito nkhuni. Chifukwa cha iwo, pamwamba "zitunda" ndi wokonzeka kumaliza. Kuyanika - khumi maola asanu;

- glyptal - zipinda youma. Kuyanika nthawi - maora twente-foro. Ntchito nthawi zambiri yekha pamwamba wosanjikiza zitsulo;

- phenol - Pulayimale wokutira nkhuni ndi zitsulo. Complete kuyanika ndi khumi ndi khumi maola.

Phunziroli kwa mapepala khoma chifukwa cha katundu gulu:

• Iwo kumathandiza mapangidwe microcracks padziko;
• kumalimbitsa m'munsi;
• Izo zikuwamanga pamalo porous ndi kuonjezera kukana kwawo kwa chinyezi;
• Amachepetsa makoma madzi mayamwidwe (zimapangitsa pamwamba "wettable") anawakonzera papering;
• bwino guluu wolimba katundu (kukakamira pa mgwirizano wa pamalo osiyanasiyana katundu);
• biocide phunziroli kwa mapepala khoma kumathandiza maonekedwe a nkhungu ndi cinoni, kumatha mavuto kuipitsidwa pamwamba.

Priming facilitates yunifolomu ntchito zomatira ndi kuchepetsa madziwo.

Theoretically, n'zotheka yoperekera ndi phunziroli pansi mapepala khoma, koma chiopsezo delamination, flaking, chilekano wakula kwambiri, kotero amapusitsa chuma ndalama si zifukwa lokha. Kugwiritsa ndi phunziroli Sikuti ngati pokhapokha ngati wosanjikiza chachiwiri ntchito kumaliza akupera putty. Pamene ntchito pa "vuto pamalo" phunziroli kwa mapepala khoma ndi mosamalitsa chofunika. Komanso ndikofunikira ntchito, ngati gawo lapansi pamwamba singakwane kapena porous, zoipa, fumbi, papezeka (ntchito chipupa chakale popanda maphunziro apadera).

Phunziroli kwa mapepala khoma anasankha malingana ndi mtundu wa mapepala khoma. Mwachitsanzo, pepala ndi polymeric mapepala khoma amasiyana guluu wolimba malinga pamwamba ndi kusamala kusankha zikuchokera phunziroli.

Kukonzekera kudenga kwa kupenta (mtundu ambiri mapeto) kovuta yolemetsa kuposa processing makoma pansi mapepala khoma la. Chifukwa chake n'chakuti utoto asamabisanso zolakwa zazing'ono ndi zolakwika, koma "zazikulu" iwo. Analimbikitsa itatha yoyamba filler wosanjikiza (mtengo) chifukwa zomatira Mkhalidwe "cobweb" (kuteteza zosayembekezereka wa microcracks chifukwa chinyezi, kutentha kusintha), ndipo wina wosanjikiza 2 putty.

Zolemba malire chidwi ayenera zimachitika ntchito, kuyeretsa ndi priming a wosanjikiza komaliza, amapereka apamwamba liza putty. The phunziroli ntchito denga ndi chimodzimodzi kwa mpanda.

Pokonzekera denga zofunika kugwiritsa ntchito kuwala mbali pamodzi m'dera ankachitira. Chifukwa chaichi, nyali pamunthu yaing'ono kapena alipidwa "kunyamula". Polozera kuwala nthawi kudziwa zopindika zotheka, kuchilango zopindika.
