Udindo wa latex ufa mu dongosolo lakunja lotchinjiriza khoma ndi zomatira matailosi

Kutsekera kwakunja kwa khoma lakunja ndikuyika malaya otchinga matenthedwe panyumbayo. Chovala chotchinjiriza chotenthetsera ichi sichiyenera kungosunga kutentha, komanso kukhala kokongola. Pakali pano, dziko langa kunja khoma kutchinjiriza dongosolo makamaka monga kukodzedwa polystyrene bolodi kutchinjiriza dongosolo, extruded polystyrene bolodi kutchinjiriza dongosolo, polyurethane kutchinjiriza dongosolo, latex ufa polystyrene tinthu kutchinjiriza dongosolo, inorganic vitrified mikanda kutchinjiriza dongosolo, etc. Kunja matenthedwe kutchinjiriza si oyenera kokha Kutenthetsa nyumba zakumpoto zomwe zimafunika kuteteza kutentha m'nyengo yozizira, komanso nyumba zokhala ndi mpweya wa m'madera akum'mwera omwe amafunikira kutentha kutentha m'chilimwe; ndi yoyenera kwa nyumba zonse zatsopano ndi kukonzanso mphamvu zopulumutsa mphamvu za nyumba zomwe zilipo; kukonzanso nyumba zakale.

① Zotsatira zakuwonjezera ufa wonyezimira wa latex mumtondo wosakanikirana wakunja kwa khoma lotsekera:

A. Kuonjezera maola ogwira ntchito;

B. Kupititsa patsogolo kasungidwe ka madzi kuti simenti ikhale ndi madzi okwanira;

C. Kuwongolera magwiridwe antchito.

② Zotsatira za kuwonjezera ufa wonyezimira wa latex pamatope olimba akunja kwa khoma lotsekera:

A. Kumamatira bwino kwa bolodi la polystyrene ndi magawo ena;

B. Kusinthasintha kwabwino kwambiri komanso kukana kwamphamvu;

C. Wabwino madzi mpweya permeability;

D. Good hydrophobicity;

E. Kulimbana ndi nyengo yabwino.

Kuwonekera kwa zomatira za matailosi, pamlingo wina, kumatsimikizira kudalirika kwa phala la matailosi. Zomangira zosiyanasiyana ndi njira zomangira zimakhala ndi zofunikira zosiyanasiyana pakumanga kwa zomatira matailosi. Pamamangidwe amakono apanyumba, njira yothira phala (zomatira zachikhalidwe) ikadali njira yayikulu yomangira. Njirayi ikagwiritsidwa ntchito, zofunikira zomatira matailosi: zosavuta kusonkhezera; zosavuta kugwiritsa ntchito zomatira, zopanda ndodo mpeni; Kukhuthala kwabwino; bwino anti-slip. Ndi chitukuko cha teknoloji yomatira matayala ndi kupititsa patsogolo luso la zomangamanga, njira ya trowel (njira yochepetsetsa) imatengedwanso pang'onopang'ono. Pogwiritsa ntchito njira yomanga iyi, zofunikira zomatira matailosi: zosavuta kusonkhezera; Mpeni womata; ntchito yabwino ya anti-slip; kunyowa bwino kwa matailosi, nthawi yayitali yotseguka.

① Zotsatira za kuwonjezera ufa wonyezimira wa latex pamatope osakanizidwa atsopano a zomatira matailosi:

A. Wonjezerani nthawi yogwira ntchito ndi nthawi yosinthika;

B. Kupititsa patsogolo kasungidwe ka madzi kuti simenti ikhale ndi madzi okwanira;

C. Limbikitsani kusagwira ntchito (poda yapadera yosinthidwa latex)

D. Kupititsa patsogolo magwiridwe antchito (osavuta kupanga pa gawo lapansi, mosavuta kukanikiza matailosi mu zomatira).

② Zotsatira zakuwonjezera ufa wa latex wowonjezera pamatope owumitsa matayala:

A. Ili ndi zomatira zabwino ku magawo osiyanasiyana, kuphatikiza konkire, pulasitala, matabwa, matailosi akale, PVC;

B. Mu nyengo zosiyanasiyana, imakhala yabwino kusinthasintha.
