Chitsulo chachitsulo chotupa
Chitoliro cha mafayilo achindunji, chimadziwikanso kuti "chitoliro cha chitoliro", chimapangidwa ndi "njira ziwiri", zomwe zimapangidwa ndi zotupa zakunja zotetezera, zomwe zimapangidwa molimba mtima pulasitiki ndi chitsulo. Zosanjikiratu zakukhosi ndi chithovu cha polyurethane chokhala ndi kambuku 60 kg / m3 mpaka 80 kg / m3, zomwe zimawonjezera chipika china, ndipo chili ndi mphamvu yolumikizana, ndikusungunuka. Polyirethane adayikamo mwachindunji matenthedwe osokoneza bongo ali ndi katundu wabwino ndi mafuta otchinga, nthawi zambiri amatha kupirira kutentha kwambiri 180 digiri ya kutentha, madzi otentha komanso owoneka bwino.
Polyirethane adayika mwachindunji chitoliro cha mafuta ndi choyenera kwa matenthedwe oumirira a media osiyanasiyana m'mitundu ya-50 {1} dikirani. Amagwiritsidwa ntchito kwambiri mu Utawuni
Ubwino wa Polyurethane mwachindunji amaika mafayilo a mafuta
1. Chepetsani mtengo wa polojekiti. Malinga ndi kuwerengera kwa madipatimenti oyenera, kuwotcha kawiri
2. Kutentha kochepa ndi kupulumutsa mphamvu. Zochita zake zimayenda: λ {{}} - 0.03kcal /
MAC ndi wotsika kwambiri kuposa zida zina zothandizira chitoto zomwe zimagwiritsidwa ntchito kwambiri m'mbuyomu, ndipo zotsatira za kusinthika ndi nthawi 4 ~ 9 nthawi. Kuphatikiza apo, njira yake yamadzi imatsika kwambiri, pafupifupi 0,2 kg / m2. Chifukwa cha mayamwidwe ochepa amadzi ndikuti kuchuluka kwa chithovu cha polyurethane kuli pafupifupi 92%. Mafuta otsika ndi mayamwidwe ochepa amadzi, kuphatikiza ndi magwiridwe osokoneza bongo a ndulu ya polyethylene yotentha kwambiri.
3. Anti-Contrizanion, luso labwino, komanso moyo wautali. Chifukwa chakuti polyurethane hardut yolimba imalumikizidwa pakhungu la chitoliro chachitsulo, kupatula kulowa kwa mpweya ndi madzi, imatha kusewera ndi mphamvu yotsutsa. Nthawi yomweyo, mabowo ake oyipa amatsekedwa, ndipo mayamwidwe amadzi ndi ochepa kwambiri. Kuchulukitsa kwambiri polyethylene chipolopolo, galasi rp chipolopolo chimakhala ndi vuto labwino, kutchinga ndi makina. Chifukwa chake, khungu lakunja la chitoliro chachitsulo ndizovuta kuwonongeka ndi mpweya wakunja ndi madzi. Malingana ngati mtundu wamkati wamapaipi umathandizidwa bwino, malinga ndi zomwe zikuchitika zakunja, moyo wa ntchito ungafike zaka zoposa 50, zomwe zilipo 3 ~ nthawi yokwera kuposa itagona.
4. Malo ochepa, zomangamanga mwachangu, komanso zabwino pa chilengedwe. Mapaipi omenyera mosabisa safunika kumanga ngalande yayikulu, kokha kuti angoika chitoliro cha kuperewera mobisa, ndikuchepetsa chomaliza cha zinthu zachilengedwe ndi konkriti zoposa 90%. Nthawi yomweyo, phulusa la kuperekera ndi tsamba la Tsamba lofanana, lokhalo lokhalokha lokha, lingafupikitse nthawi yomangayi popitilira 50%.
