Kodi mukudziwa zambiri za malo osungira zinthu ozizira?

Chipinda chosungiramo zinthu zozizira chimakhala ndi kutalika, m'lifupi ndi makulidwe okhazikika. Chipinda chosungiramo zinthu zozizira chotentha kwambiri komanso chapakati nthawi zambiri chimagwiritsa ntchito mapanelo okhuthala a 10 cm, ndipo chipinda chosungiramo zinthu zozizira chotentha kwambiri nthawi zambiri chimagwiritsa ntchito mapanelo okhuthala a 12 cm kapena 15 cm; kotero ngati sichili chipinda chosungiramo zinthu zozizira chomwe chinakonzedweratu, ndibwino kugula. Samalani kuchuluka kwa bolodi losungiramo zinthu ndi makulidwe a mbale yachitsulo. Kukhuthala kwa mbale yachitsulo ya wopanga wamba nthawi zambiri kumakhala pamwamba pa 0.4 mm. Kuchuluka kwa thovu la bolodi losungiramo zinthu zozizira ndi 38KG ~ 40KG/m3 pa mita imodzi ya kiyubiki malinga ndi muyezo wadziko lonse.

Chiyambi choyamba

Zinthu zitatu zofunika kwambiri pa bolodi losungiramo zinthu zozizira ndi kuchuluka kwa bolodi losungiramo zinthu zozizira, makulidwe a mbale yachitsulo ya mbali ziwiri, ndi mphamvu yonyamula katundu. Kuchuluka kwa bolodi losungiramo zinthu zozizira ndi kwakukulu, kotero thovu la bolodi limapangitsa kuti polyurethane ichuluke, komanso nthawi yomweyo kuwonjezera kutentha kwa bolodi la polyurethane, kotero kuti mphamvu yotetezera kutentha ya bolodi losungiramo zinthu zozizira ichepe ndipo mtengo wa bolodi uchuluke. Ngati kuchuluka kwa thovu kuli kochepa kwambiri, kungayambitse kuchepa kwa mphamvu yotetezera kutentha ya bolodi losungiramo zinthu zozizira. Pambuyo poyesedwa ndi madipatimenti oyenerera adziko lonse, kuchuluka kwa thovu la bolodi losungiramo zinthu zozizira la polyurethane ndi 35-43KG monga muyezo. Opanga ena achepetsa makulidwe a chitsulo chamtundu kuti achepetse mtengo. Kuchepa kwa makulidwe a chitsulo chamtundu kudzakhudza mwachindunji moyo wa ntchito ya bolodi losungiramo zinthu zozizira. Posankha bolodi losungiramo zinthu zozizira, makulidwe a chitsulo chamtundu wa bolodi losungiramo zinthu zozizira ayenera kudziwika.

Gulu losungiramo zinthu zozizira la polyurethane

Chosungiramo zinthu zozizira cha polyurethane chimagwiritsa ntchito polyurethane yopepuka ngati zinthu zamkati mwa chosungiramo zinthu zozizira. Ubwino wa polyurethane ndikuti ili ndi mphamvu yabwino kwambiri yotetezera kutentha. Kunja kwa chosungiramo zinthu zozizira cha polyurethane kumapangidwa ndi SII, mbale yachitsulo yamtundu wa PVC ndi zigawo za mbale yachitsulo chosapanga dzimbiri. Chifukwa cha kusiyana kwakukulu kwa kutentha pakati pa mkati ndi kunja kwa mbale, kutentha kumafalikira, zomwe zimapangitsa kuti chosungiramo zinthu zozizira chisunge mphamvu zambiri komanso kumawonjezera magwiridwe antchito a chosungiramo zinthu zozizira.
