Kutsekemera kwa makoma a polystyrene owonjezera

Tsopano, phindu la ndalama zowonjezera likuwonjezeka, chiwerengero cha anthu chikuyambanso kuganizira za kusungidwa kwa nyumba zawo. Koma kokha m'malo galasi unit sikuthandiza nthawi zonse. Mpaka 45% ya kutentha kumatuluka mumadzi ozizira ndi ofunda. Ogwira ntchito mwakhama amachititsa kuti ntchito yomanga ikhale yotentha, koma momwe angakhalire kwa anthu omwe adatengera nyumba zakale ozizira m'nyengo yachisanu "Khrushchev" kapena m'nyumba yachinsinsi. Zimathandiza kuti izi zitheke panthawi yokonzanso ntchito kumalo omwe anamangidwa kale komanso ogwiritsidwa ntchito. Ndizomwe anthu ambiri ali ndi vuto losankha kutentha kotentha kwa makoma awo. Lero tidzakuuzani zomwe zimapangitsa kuti chithovu cha extruded polystyrene chitheke, zomwe zimakhala ndi momwe zimasiyanasiyana ndi zipangizo zina zofanana.

Zizindikiro za kuwonjezereka kwa polystyrene

Kwa nthawi yoyamba chuma ichi chinalandiridwa ku America pafupi zaka makumi asanu zapitazo, ndipo mwamsanga zinakhala zofala padziko lapansi. Chinthucho ndi chakuti ali ndi makhalidwe otetezeka kwambiri pa mtengo wake wotsika mtengo. Nthaŵi zambiri ogula amasokoneza polystyrene ndi extruded polystyrene, ndi kugula zinthu zotchipa. Zinthu zonsezi zimakhala zofanana, chifukwa zipangizo zawo ndi polystyrene. Koma chithovucho chimakhala ndi mapuloteni osungunuka, ndipo kusungunula kwa poizoni wotchedwa polystyrene foam kumasanduka madzi omwe amawomberanso ndikukhazikika. Lili ndi mawonekedwe apadera, opangidwa ndi 90% a mlengalenga, omangidwa mu maselo ang'onoang'ono.

Zomangamanga zonse ndi mamolekyu a extruded polystyrene mkuntho ali ndi mphamvu yowonjezereka yowonjezereka, yomwe imapangitsa kuti thupi likhale lofunika kwambiri pomanga. Ngakhale mutangotenga zipangizo izi m'manja mwanu, mutha kuona nthawi yomweyo. Polystyrene yotsika mtengo imafalikira pa granules pansi pa kupsyinjika kwakukulu kwa zala, ndipo pofuna kuwononga zowonjezera polystyrene, zidzakhala zofunikira kuyesetsa mwakhama. Kuwonjezera apo, chithovucho chimakhala ndi malo okwanira chinyezi, kuchepa kwake kumakhudza. Ndicho chifukwa chake kuli bwino kulipira mu sitolo kwa extruded polystyrene, kuposa kulipira kusasamala kwanu ndi chuma chochuluka.

Malangizo ogwira ntchito ndi owonjezera polystyrene:

1. Zipangizozi zili ndi mawonekedwe akuluakulu ndipo makoma amafunikira kukonzekera - kuchotseratu ziphuphu, kusagwirizana, kusiyana kotheka sikuyenera kupitirira 2 masentimita. Timachotsa zonse zidutswa zamatabwa.
2. Ikani zoyambira.
3. Ngati mugwiritsira ntchito zidole za mbale pamodzi ndi guluu, ndiye kuti miyalayo idzakhala yodalirika kwambiri.
4. Nkhumba yoyamba imapangidwa pakati pa tile, kenako yonse, imachoka pamphepete mwa 10-15 masentimita.
5. Pazomwe zili ndi guluu ("Ceresite" kapena zina) ziyenera kusonyezedwa kuti zingagwiritsidwe ntchito pa bolodi la EPS.
6. Ngati khoma liri losavuta, ndiye bwino kugwiritsa ntchito njira yothetsera yothetsera.
7. Yambani kuyala kuchokera pansi, kuyika mzere woyamba wa mbale kupita pakhoma pang'onopang'ono.
8. Mzere wotsatira wa mbalewu umagwiritsidwa ntchito poyang'ana pa bolodi, potenga zovala.
9. Ntchito yomanga iyenera kuchitika m'nyengo yozizira, yotentha ndi kutentha kwa mpweya wa madigiri 5 Celsius.
10. Zonse zomwe zingatheke pakati pa slabs ziyenera kuti zisindikizidwe, ngati kusiyana kuli kwakukulu (0.5-2 cm), ndiye mutha kugwiritsa ntchito chithovu chokwera.
11. Kutsekemera kumafunika kutetezedwa ku dzuŵa ndi mphepo poziphimba ndi kudumpha kapena pochita ntchito zomwaza.

Kuti mumvetse momwe kusindikiza kwa makoma a polystyrene wowonjezereka kumadutsa zipangizo zakale komanso zachizolowezi, apa pali ziwerengero. Chingwe cha masentimita khumi ndi awiri (12 cm) chachitsulo chathu chotsekerera chimalowetsa khoma la masentimita 45 la nkhuni, njerwa ziwiri zamitala zokhazikika, 4m 20 cm ya konkire yowonjezeredwa. Mfundo yakuti polystyrene yowonjezereka ikhoza kupirira zinthu zakuthupi ndipo ndizokwanira zokwanira (moyo wautumiki umatha zaka 50), umalola kuti ugwiritsidwe ntchito kusungira makoma , komanso pansi, madenga, maziko. Koma ngakhale kumakhala mosavuta kudula komanso kosavuta kugwira ntchito, ngati chithovu. Ojambula amapanga tile mtundu wamtundu umene umachepetsa ntchito yopangira. Kuphatikiza apo, phokoso lotero ndi chitetezo ku chimfine pamalo pomwe mapepala akuphatikizidwa.
