Malangizo Ogwiritsira Ntchito:
Musanagwiritse ntchito, chotsani mafuta ndi fumbi pamwamba ndikupopera madzi pang'ono. Musanagwiritse ntchito, gwedezani thovu la polyurethane kwa masekondi osachepera 60 kuonetsetsa kuti zinthuzo zikugawidwa mofanana. Ngati mukugwiritsa ntchito mfuti-imbani thovu la polyurethane, tembenuzani chitinicho ndikuchikokera pamfuti, tembenuzani kuti mutsegule valavu yotuluka, sinthani kuchuluka kwake, ndiyeno poperani. Ngati mukugwiritsa ntchito thovu la tubular polyurethane, kulungani mphuno ya pulasitiki pa ulusi wa vavu, gwirizanitsani chubu la pulasitiki ndi mpata, ndipo kanikizani mphunoyo kuti mupope. Samalani ndi liwiro kupopera mbewu mankhwalawa; nthawi zambiri, utsi mpaka theka la voliyumu yodzaza yofunikira. Mukadzaza mipata yowongoka, gwiritsani ntchito kuchokera pansi mpaka pamwamba. Podzaza mipata monga ya padenga, chithovu chosachiritsika chikhoza kugwa chifukwa cha mphamvu yokoka; tikulimbikitsidwa kuti mupereke chithandizo choyenera mwamsanga mutatha kudzaza, ndikuchotsani chithandizo pokhapokha chithovu chikachiritsa ndikumamatira ku makoma apakati. Chithovucho chimatuluka pakatha mphindi 10, ndipo chikhoza kudulidwa pakatha mphindi 60. Dulani chithovu chochuluka ndi mpeni, kenaka pangani matope a simenti, utoto, kapena silicone sealant pamwamba. Kapenanso, yezani chotulutsa thovu molingana ndi zofunikira zaukadaulo, tsitsani ndi 80 kuchuluka kwa madzi kuti mukonze chithovu; kenako gwiritsani ntchito makina opangira thovu kuti muzitha kutulutsa thovu, ndi kuthira thovulo m'chitsime{14}}osakanizika a simenti ya magnesium oxychloride molingana ndi kuchuluka kwake, ndikugwedezani bwino. Pomaliza, dyetsani thovu la magnesium oxychloride slurry mu makina omangira kapena nkhungu kuti mupange thovu.
Njira Zodzitetezera Pakumanga: Kutentha kwanthawi zonse kwa thovu la polyurethane ndi +5-+40 digirii , ndi kutentha kokwanira bwino ndi +18-+25 digiri . M'malo otentha-otsika, tikulimbikitsidwa kuti muyike malonda pamalo otentha osasinthasintha a +25-+30 kwa mphindi 30 musanagwiritse ntchito kuti muwonetsetse kuti ikugwira ntchito bwino. Chithovu chochira chimakhala ndi kutentha kosasunthika kwa madigiri -35 digiri -+80 .
Foam polyurethane ndi chinyontho-chithovu chochiritsa. Iyenera kupopera pamwamba pa chinyontho; Kuchuluka kwa chinyezi, kuchira msanga. Chithovu chosachiritsika chingathe kutsukidwa ndi mankhwala oyeretsera, pamene chithovu chochiritsidwa chiyenera kuchotsedwa ndi makina (kudula mchenga kapena kudula). Chithovu chochiritsidwa chidzakhala chachikasu pambuyo pa kukhudzana ndi kuwala kwa ultraviolet; tikulimbikitsidwa kuvala thovu lochiritsidwa ndi zinthu zina (matope a simenti, utoto, etc.). Mukamaliza kugwiritsa ntchito, yeretsani mfuti yopopera nthawi yomweyo ndi wodzipatulira woyeretsa.
Mukasintha chitinicho, gwedezani chitini chatsopanocho bwinobwino (nthawi zosachepera 20), chotsani chitini chopanda kanthu, ndipo m'malo mwake sinthani ndi chitini chatsopano kuti mfuti ya spray isawume.
Valve yowongolera kuthamanga ndi choyambitsa cha mfuti yopopera imawongolera kuthamanga kwa thovu. Pamene kupopera mbewu mankhwalawa kuyimitsa, nthawi yomweyo kutseka valavu otaya molunjika.
Chitetezo:
Chithovu chosachiritsika chimamatirira pakhungu ndi zovala; pewani kukhudzana ndi khungu ndi zovala pakugwiritsa ntchito. Foam ya polyurethane imatha kukhala ndi mphamvu ya 5-6 kg/cm² (madigiri 25). Pa yosungirako ndi zoyendera, kutentha sayenera upambana 50 digiri kuteteza akhoza kuphulika. Peŵani kuwala kwa dzuwa ndi kusunga kutali ndi ana. Zitini zopanda kanthu, makamaka zogwiritsidwa ntchito pang'ono, siziyenera kutayidwa mosasamala. Osawotcha kapena kuboola zitini zopanda kanthu. Khalani kutali ndi moto wotseguka ndi zinthu zoyaka kapena zophulika. Malo omangapo ayenera kukhala ndi mpweya wabwino. Ogwira ntchito ayenera kuvala magolovesi, zovala zantchito, magalasi otetezera chitetezo, ndipo sayenera kusuta. Ngati chithovu chikalowa m'maso, chambani ndi madzi ndipo pitani kuchipatala. Ngati ifika pakhungu, ichapa ndi sopo ndi madzi.
