Hiah Modulus Construction Joint Sealant Lejell 220
Mafotokozedwe Akatundu
Lejell-220 ndi chigawo chimodzi, chinyezi chochiritsika polyurethane sealant. Kusindikiza kwabwino komanso magwiridwe antchito osinthika. Palibe dzimbiri ndi kuipitsa zinthu m'munsi ndi chilengedwe-wochezeka.Pricking kukana, zosavuta kukonza. Kulumikizana bwino ndi simenti ndi miyala.
Zosindikizirazi zimabwera m'njira zosiyanasiyana, monga machubu, makatiriji, kapena zitini, ndipo zitha kugwiritsidwa ntchito pogwiritsa ntchito mfuti zowombera kapena zida zina. Nthawi zambiri amakhala ndi kukhazikika kokhuthala komwe kumawalola kudzaza mipata ndikutsatira malo osagwirizana bwino. Zomangira Zomangamanga zimapereka mgwirizano wamphamvu pakati pa zida, kuchepetsa kufunikira kwa zomangira zowonjezera kapena zomangira zamakina.
Magawo Ogwiritsa Ntchito
Oyenera kumadera omwe kuyenda kochepa, kukana kwambiri kulowa mkati ndi kupanikizika kumafunika.
Oyenera kusindikiza madzi kumbuyo kwa milatho ndi tunnel, mapaipi a ngalande ndi zinthu zina zopanda madzi,
Kwa gulu la precast, khoma lamkati la konkriti ndi kulumikizana ndi miyala ndi kusindikiza.

Zina Zambiri
Guangdong Pustar Adhesives & Sealants Co., Ltd. ndi akatswiri opanga polyurethane sealant ndi zomatira ku China. Kampaniyo imaphatikiza kafukufuku wasayansi, kupanga ndi kugulitsa. Sikuti ili ndi malo ake aukadaulo a R&D, komanso imagwirizana ndi mayunivesite ambiri kuti apange kafukufuku ndi chitukuko kachitidwe ka ntchito.
Makina odzipangira okha "PUSTAR" polyurethane sealant adayamikiridwa kwambiri ndi makasitomala chifukwa chokhazikika komanso chabwino kwambiri. Mu theka lachiwiri la 2006, poyankha kusintha kwa msika, kampaniyo idakulitsa mzere wopanga ku Qingxi, Dongguan, ndipo masikelo opanga pachaka afika matani oposa 10,000.
Kwa nthawi yayitali, pakhala pali kutsutsana kosasinthika pakati pa kafukufuku waukadaulo ndi kupanga mafakitale kwa zida zosindikizira za polyurethane, zomwe zalepheretsa kukula kwamakampani. Ngakhale padziko lapansi, makampani owerengeka okha ndi omwe angakwaniritse kupanga kwakukulu, koma chifukwa cha zomatira zolimba kwambiri komanso zosindikiza, kukopa kwake pamsika kukukulirakulira pang'onopang'ono, ndipo kukula kwa zomatira za polyurethane ndi zomatira kuposa zosindikizira zachikhalidwe za silikoni ndizomwe zikuchitika. .
Potsatira izi, Pustar Company yachita upainiya wa "anti-experiment" njira yopangira kafukufuku ndi chitukuko cha nthawi yayitali, inatsegula njira yatsopano yopangira zinthu zazikulu, zogwirizana ndi gulu lazamalonda, ndipo yafalikira padziko lonse lapansi. dziko ndi kutumizidwa ku United States, Russia ndi Canada. Ndipo ku Europe, gawo logwiritsira ntchito ndilodziwika pakupanga magalimoto, zomangamanga ndi mafakitale.
