Lero tili ndi gulu la mapanelo osungira ozizira omwe amatumizidwa ku Australia.Iye ndi kasitomala wathu wanthawi yayitali yemwe wagwirizana nafe kuyambira masiku oyamba akampani ndikugula mapanelo a polyurethane kuchokera kwa ife.

Ubwino wogwiritsa ntchito mapanelo osungira ozizira ndi chiyani pomanga posungirako kuzizira?

Ubwino wa kusungirako kuzizira umagwirizana ndi firiji yogwiritsidwa ntchito ndi zipangizo zomwe zimagwiritsidwa ntchito.Pomanga malo osungira ozizira, pafupifupi 90% ya teknoloji yathu yosungiramo kuzizira imagwiritsa ntchito bolodi yosungirako ozizira, chifukwa ili ndi ubwino wotsatira.

1. Bokosi losungirako kuzizira liri ndi zizindikiro za kukana mwamphamvu kwa deformation, osati kosavuta kusweka, ndi kukhazikika.Mapangidwe a pore a polyurethane material ndi okhazikika komanso otsekedwa, omwe samangokhala ndi kutsekemera kwabwino kwa kutentha ndi ntchito ya antifreeze, komanso amakhala ndi mayamwidwe abwino amawu.Pogwiritsa ntchito ndi kukonza bwino, moyo wanthawi zonse wogwirira ntchito wokhazikika wa polyurethane thovu kutchinjiriza dongosolo amatha kufika zaka zoposa 30.Itha kugwiritsidwa ntchito nthawi zonse pakanthawi kamangidwe, kowuma, konyowa kapena galvanic corrosion, ndipo mtengo wowonjezera udzatenthedwa ngati chithovu cha tizilombo, mafangasi kapena algal ndi okwera mtengo kuposa zida zina wamba komanso kuchepetsa kwambiri. pamitengo yozizirira.

2. Bokosi losungirako kuzizira limakhala ndi mphamvu yochepetsera kutentha kwa kutentha komanso kutsekemera kwa madzi ndi chinyezi: zinthu zolimba za polyurethane zimakhala ndi coefficient yotsika yotentha komanso kutentha kwabwino.Kukula kwa polyurethane kuli ndi ntchito yoteteza chinyezi komanso madzi.Pamene chatsekedwa selo chiŵerengero cha okhwima polyurethane upambana 90%, ndi hydrophobic kusanthula zakuthupi, amene sangawonjezere chifukwa mayamwidwe chinyezi ndi matenthedwe madutsidwe, ndipo sipadzakhala kutayikira pakati pa makoma.

3. Bokosi losungirako kuzizira liri ndi makhalidwe oletsa moto, kutentha kwa moto, kukana kutentha kwambiri komanso kutsekemera kwabwino kwa mawu.Powonjezerapo zoletsa moto, polyurethane ndi chinthu chozimitsa moto chozimitsa moto chomwe chimakhala ndi kufewetsa kopitilira 250 digiri Celsius ndipo chimawola pakatentha kwambiri.Kuonjezera apo, phulusa likhoza kupanga pamwamba pa chithovu pamene polyurethane ikuwotcha, zomwe zimathandiza kubisa chithovu pansi.Ikhoza kuteteza kufalikira kwa moto, ndipo polyurethane sichitulutsa mpweya woipa pa kutentha kwakukulu.
