Chophimba cha polyurea chokonzanso makoma: Njira yatsopano yosawononga chilengedwe komanso yothandiza kwambiri pa nyumba
Pankhani ya kukula kosalekeza kwa kufunika kwa kukonzanso mizinda ndi kukonzanso nyumba zakale, mtundu watsopano wa zinthu zokutira khoma zomwe zimaphatikizapo kusamala chilengedwe, kulimba komanso kukongola - zokutira za polyurea - pang'onopang'ono zikukhala "zokondedwa zatsopano" mumakampani omanga. Posachedwapa, mapulojekiti okonzanso madera akale okhala m'madera ambiri ayamba kugwiritsa ntchito ukadaulo wa zokutira za polyurea, zomwe zikupereka njira yatsopano yokonzanso makoma.
Zatsopano Zaukadaulo: Ubwino "Waukulu" wa Zophimba za Polyurea
Zophimba za polyurea ndi mtundu wa zinthu zopangidwa ndi elastomer zomwe zimapangidwa ndi zinthu za isocyanate ndi amino compounds. Zili ndi makhalidwe monga kuchira mwachangu kwambiri, kusinthasintha kwakukulu, kukana dzimbiri, komanso mphamvu zoletsa kukalamba. Poyerekeza ndi utoto wachikhalidwe wa latex, matailosi a ceramic, ndi zinthu zina zokonzanso, mphamvu zawo zomangira zimawonjezeka ndi nthawi 3-5. Kugwiritsa ntchito kamodzi kokha kumatha kukwaniritsa ntchito zingapo monga kuletsa madzi kulowa, kuletsa chimfine, komanso kukana kuwonongeka, ndipo sikufunika kukonza pafupipafupi. Nthawi yawo yogwira ntchito imatha kufika zaka zoposa 10.
Kulimbikitsa chilengedwe: Kumanga kobiriwira kumathandiza kuti chitukuko chikhale chokhazikika
Zinthu zachilengedwe zomwe zimapangidwa ndi polyurethane coverage nazonso zakopa chidwi cha anthu ambiri. Pa nthawi yomanga, sizitulutsa ma VOC (mankhwala osungunuka achilengedwe), kupewa fungo loipa komanso kuipitsidwa kwa mpweya komwe kumachitika panthawi yomanga coverage yachikhalidwe; nthawi yomweyo, zinthuzo zimatha kubwezeretsedwanso, kukwaniritsa zofunikira za njira ya "dual carbon" yosinthira malo omanga. Akatswiri ochokera ku China Academy of Building Research adati: "Kukwezedwa kwa kuvala kwa polyurethane coverage ndi chizindikiro chofunikira cha kusintha kwa ntchito yokonzanso nyumba kuchoka pa 'kugogomezera zotsatira' kupita ku 'kugogomezera njira'."
Kukula kwa kuchuluka kwa ntchito: Kufalikira kwamitundu yambiri kuyambira m'magawo okhala anthu ambiri mpaka mafakitale
Pakadali pano, ukadaulo watsopano wogwiritsira ntchito zokutira za polyurea wakhala ukugwiritsidwa ntchito kwambiri m'madera okhala anthu, nyumba zamalonda, mafakitale, ndi madera ena. M'mafakitale, kukana kwake asidi ndi alkali, komanso kukana kugundana, kumatha kuthana bwino ndi malo ovuta monga zomera zamankhwala ndi nyumba zosungiramo zinthu; m'mafakitale, zokutira zotanuka kwambiri zimatha kusintha mawonekedwe a nyumbayo ndikupewa ming'alu ina.
Kuyambira "kukonza" mpaka "kukonzanso", zokutira za polyurethane zikugwiritsa ntchito mphamvu zaukadaulo kusintha "mawonekedwe" ndi "thanzi" la nyumba za m'mizinda. Chifukwa cha chithandizo cha mfundo komanso kufunika kwa msika, zinthu zatsopanozi zitha kutsogolera kusintha kwina pankhani yokonzanso makoma.
