Kodi Spray PolUrethan chithovu chokhazikika ndi chiyani?

Masiku ano kusokonezeka kwa mafuta ndi chinthu chachikulu kwambiri chopulumutsa mphamvu. Pakadali pano, okhazikika polurethane chithovu chomwe chatseka mawonekedwe a cell ndi zinthu zomwe zimakhala ndi zotsatsira zotsika kwambiri (0,018 - 0.022 w / mk) padziko lapansi. Mtundu wamtunduwu wa polyirethane ungagwiritsidwe ntchito mosavuta ndi kupopera mbewu pamtunda momwe zimasinthira kutentha ndikofunikira. Polyirethane amatsatira ndikukula pansi ndikupanga thovu losanjikiza 20 - 40 Kg

Kodi Spray Callsurethane amafunsira bwanji?

Makina opukusira akufunika kuti agwiritse ntchito thovu la polyurethane iyi. This machine withdraws polyol and isocyanate components from their drums, heats them up to 35-45℃ and pumps them to their hoses with high pressure. Mbaleyo amatenthedwanso kutentha komweko kuti ateteze zigawo zikuluzikulu. Pambuyo pa 15 - 30 m kutalika, zida za polychol ndi Isoctate zidaphatikizidwa mu chipinda chosakanikirana cha pistol. Pamene pistol yakokedwa, zigawo zikuluzikulu zomwe zimabwera kwa pistol zimasakanikirana ndikuthiridwa pansi mothandizidwa ndi mpweya wopanikizika. Ma polylol ndi Isoctaniate zikuluzikulu zimakhudzana wina ndi mnzake akasakanikirana ndipo amakula atafika pamtunda ndikupanga mawonekedwe a polyurethane. Mu masekondi, wokutira wa polyurethane amalira mafuta ogwiritsira ntchito matenthedwe.

Kutulutsa kwamafuta a utsi wapyurethane

Kupukusira zikopa za poldurethara kumakulitsidwa ndi mankhwalawa onse awiri owombera (madzi) ndi kuwombera (zowombera) Popeza mtundu wamtunduwu watseka maselo ambiri, mipweya yomwe imapangidwa kuchokera ku zowombera (carbondoxide ndi hydrocarbon mpweya) zimakodwa mkati mwa khungu la chithovu. Pakadali pano mafuta a thovu, omwe ndi osokoneza bongo omwe amakutuwa, amakhudzidwa ndi magawo atatuwa pansipa.
