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, zomwe zimachepetsa mphamvu yoteteza kutentha kwa bolodi losungiramo zinthu zozizira ndikuwonjezera mtengo wa bolodi. Ngati kuchuluka kwa thovu kuli kochepa kwambiri, kungayambitse kuchepa kwa mphamvu yoteteza kutentha kwa bolodi losungiramo zinthu zozizira. Pambuyo poyesedwa ndi madipatimenti oyenerera adziko lonse, kuchuluka kwa thovu la bolodi losungiramo zinthu zozizira la polyurethane nthawi zambiri kumakhala 35-43KG monga muyezo. Opanga ena amachepetsa makulidwe a chitsulo chamtundu kuti achepetse mtengo. Kuchepa kwa makulidwe a chitsulo chamtundu kumakhudza mwachindunji moyo wa ntchito yosungiramo zinthu zozizira. Posankha bolodi losungiramo zinthu zozizira, makulidwe a chitsulo chamtundu wa bolodi losungiramo zinthu zozizira ayenera kudziwika.
Bolodi losungiramo zinthu zozizira la polyurethane
Bolodi yosungiramo zinthu zozizira ya polyurethane imagwiritsa ntchito polyurethane yopepuka ngati zinthu zamkati mwa bolodi yosungiramo zinthu zozizira. Ubwino wa polyurethane ndikuti kutentha kwake kumakhala bwino kwambiri. Kunja kwa bolodi yosungiramo zinthu zozizira ya 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 malo osungiramo zinthu zozizira azisunga mphamvu zambiri komanso zimathandizira kuti malo osungiramo zinthu zozizira azigwira ntchito bwino.
Sankhani bolodi losungiramo zinthu zozizira
Ubwino wa bolodi losungiramo zinthu zozizira la polyurethane ndi wofunika kwambiri pa malo osungiramo zinthu zozizira, chifukwa malo osungiramo zinthu zozizira ndi osiyana ndi malo osungiramo zinthu wamba, kutentha kwa malo osungiramo zinthu zozizira nthawi zambiri kumakhala kochepa, ndipo kutentha kwa mpweya, chinyezi, ndi zofunikira zachilengedwe zimakhala zochepa. Chifukwa chake, posankha bolodi losungiramo zinthu zozizira la polyurethane, tiyenera kusamala posankha bolodi losungiramo zinthu zozizira la polyurethane lokhala ndi kutentha koyenera. Zinthu zomwe zili mu malo osungiramo zinthu zozizira zimawonongeka, kapena compressor yoziziritsa ya malo osungiramo zinthu zozizira imagwira ntchito pafupipafupi, zomwe zimawononga ndalama zambiri ndikuwonjezera mtengo. Kusankha mbale yoyenera kungathandize kusunga malo osungiramo zinthu zozizira bwino.
