ETPU Ndondomeko Yomanga Pansi Pansi Yapulasitiki

ETPU (Zowonjezera thermoplastic polyurethane) ndi zinthu ngati popcorn. Pambuyo kukakamizidwa ndi kutentha mankhwala, buku la TPU tinthu tating'onoting'ono timachulukirachulukira ka 10, ndikupanga tinthu tating'onoting'ono tomwe timatulutsa thovu tomwe timakhala ndi tinthu tating'ono tating'ono tating'ono, tofanana ndi "popcorn". ETPU zakuthupi ali ndi elasticity yayikulu ndipo amatha kuyamwa bwino ndikuchepetsa kuvulala komwe kumachitika chifukwa cha kugwa ndi ngozi. Izi zimagwiritsidwa ntchito kwambiri m'mabwalo amasewera, mabwalo amasewera kusukulu, komanso kuchulukirachulukira m'misewu yolimba m'matauni, ma greenways, ndi malo osewerera a kindergarten.

Njira Yachindunji Yomanga

Konzani Zipangizo

Zomatira, zomatira pagawo limodzi, ETPU ma granules, utoto wa polyurethane wopangidwa ndi madzi, chopukusira ngodya, makina opopera opanda mpweya, chitsulo chamagetsi, mpeni wowotcha, wodzigudubuza, burashi, zida zoyezera, chosakanizira chamagetsi, mapepala okongoletsa, ndi zina zambiri.

Konzani Maziko

Konkire yomwe yangotsanulidwa kumene iyenera kukhala ndi nthawi yochiritsa (masiku osachepera 28 m'chilimwe, ndikuwonjezera koyenera m'nyengo yozizira). Mabowo ndi ming'alu ziyenera kukonzedwa ndi matope a simenti. Pansi pa maziko ayenera kukhala olimba komanso osalala, ndipo wosanjikiza uliwonse pa konkire uyenera kudulidwa ndi chopukusira. Magulu a mphamvu zamapangidwe asakhale otsika kuposa C20. Tsukani bwino pansi, kuchotsa zonyansa zonse monga mafuta, zotsalira za mafuta, zotsalira za utoto, mankhwala, ndi matope. Yesani chinyontho cha nthaka, ndipo chinyezi chiyenera kukhala ≤8% musanapite ku sitepe yotsatira yomanga (ikani tepi yowonekera mwamphamvu pansi, ndipo patatha maola anayi, pasakhale madontho a madzi owonekera pa tepi).

Kupaka kwamadzi Primer

Pansi pakukonzedwa ndikutsukidwa, mutha kupitiliza ndikugubuduza pa choyambira chopanda madzi. Izi zimathandiza kupititsa patsogolo luso la mgwirizano pakati pa maziko ndi pamwamba, komanso kumalimbitsa chitetezo cha madzi ndi kugwirizana. Gwiritsani ntchito chodzigudubuza kuti mugwiritse ntchito poyambira, kuwonetsetsa kuti pamwamba panyowa kwathunthu popanda mawanga osowa. Pewani kugwiritsa ntchito zoyambira zambiri, chifukwa zimatha kuyambitsa thovu pansi pa pulasitiki, zomwe zimakhudza kukongola ndi mtundu. Njirayi imakhala ndi malaya awiri: malaya oyamba olowera ndi kuchiritsa, malaya achiwiri ndi osindikiza.

Kusakaniza Tinthu

Thirani particles mu chidebe chosindikizidwa. Onjezerani zomatira zamagulu amodzi ku particles mu chiŵerengero cha 2.5-4: 1 (tinthu tomatira). Sakanizani kusakaniza kwa mphindi 5 mpaka 10, kapena mpaka mutasakanizidwa bwino.

ETPU kuyika kwa granule

Pamaso kuyala particles, ntchito wosanjikiza wa mkulu-kugwirizana zomatira. Mukasakaniza bwino tinthu tating'onoting'ono, titsanulirani pansi. Gwiritsani ntchito trowel ya PU kuti mufalitse tinthu tating'onoting'ono. Kenako, gwiritsani ntchito makina apadera opaka makina kuti muzitha kumangiriza ndi kuphatikizira tinthu tating'onoting'ono pa makulidwe ake, ndikuwonetsetsa kuwongolera kuchuluka ndi makulidwe. Ngati pali madera osagwirizana, pitirizani kuwasandutsa.

Perekani zokutira madzi opangidwa ndi polyurethane 

Pambuyo maola 48 kuyanika kwa ETPU ma granules, sakanizani bwino zigawo A ndi B za polyurethane yamadzi yamadzi kwa mphindi zitatu, kenaka tsitsani mofanana pogwiritsa ntchito makina opopera opanda mpweya.

CHENJEZO

1. Kutentha kozungulira pamalo omangapo kuyenera kukhala pamwamba pa 5 ℃, ndipo chinyezi kuyenera kukhala pansi pa 80% pomanga.
2. Womangayo ayenera kusunga zolemba za malo omangawo, nthawi, kutentha, chinyezi, kutentha kwapansi, zipangizo, ndi zina zotero, kuti azigwiritsa ntchito mtsogolo.
3. Moto wotseguka ndi woletsedwa m'malo omanga.
4. Pofuna kupewa kuipitsidwa kwa m'mphepete mwa zomangamanga ndikusunga mzere wowongoka kwathunthu (kapena malire ndi malo osakhala otsekedwa), tepi yotetezera iyenera kuikidwa. Samalirani ukhondo pogwira zosakaniza ndi zida zopewera zonyansa.
5. Panthawi yomanga, tsatirani mfundo za "kukonzekera zodzipatulira, magulu ang'onoang'ono angapo, ndi kupereka mosalekeza". Konzani ndikugwiritsa ntchito kusakaniza nthawi yomweyo, ndipo gwiritsani ntchito tinthu tosakanikirana mkati mwa ola limodzi. Gwiritsani ntchito choyambira chokonzekera mkati mwa mphindi 1.
