Maukadaulo a Thigid Foam Pom Heyirethane mundawo
Rigid Foam Polyurethane (PU) zotchinga ndi polymer yokhala ndi gawo lobwereza la gawo la carbamate, lopangidwa ndi zomwe Isocynateate ndi Polyyannate ndi Polyl. Chifukwa cha magwiridwe ake abwino kwambiri ndi magwiridwe ake, imapeza mapulogalamu ambiri okhudzana ndi khoma lakunja komanso kusungirako kozizira, malo osungirako arrive, ma pichesi ndi zina zapadera zamagetsi.
Pakadali pano, kusiya kuyika kwa denga komanso kugwiritsa ntchito zosafunikira, kumathandizanso zinthu zosiyanasiyana monga malo osungira ozizira komanso akulu okhazikika pakanema.
Tekinolo yofunikira ya zingwe zolimba za polinthane utsi
Thestery of Rigid Foam Porawalting Technology imabweretsa zovuta chifukwa cha zovuta zomwe zingakhale ngati mabowo osowa. Ndikofunikira kuwonjezera maphunziro a anthu omanga kuti atha kupirira maluso othilirawo komanso kuthetsa mavuto omwe amakumana nawo popanda kuyerekezera pakumanga. Zovuta Zaukadaulo Wapamwamba Popanga zomanga zopopera zimayang'ana pazinthu zotsatirazi:
Kuwongolera nthawi yoyera komanso yoyera.
Kupanga kwa thovu la polyurethane kumaphatikizapo magawo awiri: kumenyedwa ndi kuchiritsa.
Kuchokera kusakanikirana kosakanikirana mpaka kukula kwa kutha kwa chisomu - njirayi imadziwika kuti thovu. Mu gawo ili, kufanana mu dzenje la budbble kuyenera kuganiziridwa kuti gawo lotentha lotentha limatulutsidwa mu dongosolo lazomwe amathira. Kuwira kwa bubble makamaka kumadalira zinthu monga:
1. Kupatuka kwakuthupi
Palinso mphamvu zazikulu zapamwamba pakati pa zikwama zamakina zomwe zimapangidwa motsutsana ndi zomwe adazipanga pamanja. Nthawi zambiri, ma ratios opangidwa ndi makina ndi 1: 1; Komabe chifukwa cha kuchuluka kwa maulendo a maulendo opanga - zinthu zenizeni sizingagwirizane ndi ma ratios osinthika omwe amatsogolera ku kusagwiritsa ntchito zoyera kapena zakuda.
Kutentha kwa 2.
Matalala a polyirethara amakhala okonda kutentha; Njira yawo yovutayi imadalira kwambiri kupezeka kwa kutentha komwe kumachokera ku mitundu yonse iwiri yochitira mankhwala mkati mwa makina ogwirizana ndi zilengedwe.
Pamene kutentha kokwanira kumakhala kokwanira kuti chilengedwe chikhale chotentha - chimathandizira kuthamanga kwa chilengedwe chomwe chimapangitsa kuti zitsamba zowonjezeredwa mokwanira ndi zikopa zopitilira pansi.
Makamaka pamatenthedwe otsika (mwachitsanzo, m'munsi mwa 18 ° C), zina mwazomwe zimapangitsa kuti zikhale nthawi youmba yochulukirapo mogwirizana ndi mitengo yokwera ponseponse.
3.Ndipo
Pa nthawi yopopera mpweya kuthamanga kwa mphepo ayenera kukhalabe pansi pa 5m / s; Kupitilira muyeso kumeneku kumawononga kutentha komwe kumachitika komwe kumachitika pakupanga zinthu mwachangu popanga zolengedwa kumawonekera.
4.Base kutentha & chinyezi
Kutentha kwa khoma kukhoma kumapangitsa kuti poureurethane's Firecycy nthawi zambiri makamaka ngati matedi am'munda ndi otsika - mwachangu kwambiri - mwachangu amayamba kufalikira kwa zinthu zonse.
Chifukwa chake kuchepetsa masana nthawi ya zomangira limodzi ndi makonzedwe opanga makonzedwe kukhala kofunikira pakuwonetsetsa kuti ndi okwera okwanira okwanira polyuretherethane.
Rigid polurethane chithovu chimayimira mtengo wopangidwa ndi polymer wopangidwa kudzera muzochitika pakati pa zigawo ziwiri - isocyunanate & kuphatikiza polyther.
Zigawo za Isocyyate zimachita mosavuta ndi madzi kutulutsa zomangira za Urea; Kuchuluka kwa Urea Bow Forvers Rementers chifukwa cha chiuno cha Brity Poyerekeza pakati pawo & fumbi / chinyezi
