Chithovucho chimakhalanso ndi mawonekedwe amtundu wamagulu atatu okhala ndi mawonekedwe otseguka opitilira 99%, omwe samangolola kuti mafunde amawu azitha kusinthidwa kukhala mphamvu ya grid vibration ndikudyedwa ndi kuyamwa, kuwonetsa magwiridwe antchito abwino kwambiri, komanso mogwira mtima. imalepheretsa kutengera kutentha kwa mpweya.Kuonjezera apo, kukhazikika kwake kwapadera kwa kutentha kumapangitsa kuti azikhala ndi kutentha kwabwino komanso kutentha.
Kuphatikiza apo, pulasitiki yofewa ya Yadina ya melamine imakhala ndi kachulukidwe kokha 8-10Kg/m3, kupangitsa kuti ikhale yosinthika kwambiri.Itha kugwira ntchito m'malo oyambira kutentha kwa -200 ℃ mpaka kutentha kwambiri kwa 200 ℃.Amagwiritsidwa ntchito kwambiri pomanga nyumba, mabwalo amasewera, zida zamafakitale, zinthu zamagetsi, magalimoto, mabatire amagetsi, njanji yothamanga kwambiri, ndege, ndikuyenda.Ndikoyenera makamaka kuyamwa kwa mawu, kuchepetsa phokoso, kuchepetsa kugwedezeka, kutsekemera, ndi kusunga kutentha pansi pazimenezi zimalepheretsa moto komanso kutentha kwambiri.Pulasitiki ya Yadina's melamine foam ilinso ndi mphamvu zoyeretsa mozizwitsa komanso kuyamwa kwamadzi kwambiri komanso kusunga chinyezi, zomwe zimapangitsa kuti zizigwiritsidwa ntchito kwambiri m'malo monga ulimi wopanda dothi ndi makatiriji a inki.
Thovu lofewa la Yadina la melamine lili ndi m'lifupi mwake mpaka 1300mm, kutalika mpaka 400mm, ndipo limatha kusinthidwa kutalika kwake.The 1300mm m'lifupi akukumana chofunika zipangizo zambiri mafakitale pepala ndi m'lifupi mwake 1000mm.
Chithovu chofewa cha Yadina cha melamine chimabwera mumitundu yoyera, imvi, kapena makonda ena.Makulidwe osiyanasiyana ndi mbiri zitha kusinthidwa malinga ndi zomwe makasitomala amafuna kuti akwaniritse zosowa zamalo osiyanasiyana.
Zomwe zimagwiritsidwa ntchito nthawi zonse ndi filimu ya pulasitiki ya polyethylene.
Pogwiritsa ntchito thovu la Yadina melamine ndi mbiri, kuwongolera uku kwa magawo osiyanasiyana kumatha kuchitika:
1, Kukonza makina:
Yadina melamine thovu amatha kukonzedwa kukhala chinthu chimodzi mwa kudula ndi kukanikiza.Itha kusinthidwanso kukhala ma sheet ndi mawonekedwe ovuta a geometric osakhazikika pogwiritsa ntchito njira zopangira monga kupanga, kudula, ndi mphero, ndipo pamwamba pake imatha kusinthidwa kukhala zinthu zowoneka ngati zowoneka bwino zamtundu wa chevron kuti zikwaniritse zofunikira zomvera.
2, zokutira pamwamba:
Pofuna kupaka utoto kapena kukonza zinthu zamakina, thovu la Yadina melamine limatha kuphimbidwa ndi kupopera mbewu mankhwalawa, kugudubuza, ndi kupaka.
3, kulumikizana ndi kumizidwa:
Chifukwa cha kukana kwake kwamankhwala, zomatira wamba monga acrylic resin zitha kugwiritsidwa ntchito polumikiza thovu la Yadina melamine.Zomatira zosungunulira zosungunulira ndi reactive resin zitha kugwiritsidwanso ntchito poganizira kukana kwawo kwamankhwala.Madzi owonjezera amatha kutulutsidwa ndi mapasa-screw extruder kuti afulumizitse kuyanika.
4, kukanikiza kotentha:
Mapepala a thovu a Yadina melamine amatha kupangidwa kukhala denga lokhala ndi mawu komanso mipukutu pogwiritsa ntchito nkhungu zotentha, pomwe mphamvu yakumtunda imakhalanso bwino.Zitha kuphatikizidwa mosavuta ndi zinthu monga zitsulo zachitsulo, nsalu, ndi nsalu zopanda nsalu kuti apange mndandanda wazinthu zotsekemera, zotsekemera, ndi zotsekemera zotentha kuti zikwaniritse zosowa za malo osiyanasiyana ndi malo ogwira ntchito.
5, Kuthamangitsa madzi ndi mafuta:
Kuchotsa madzi ndi mafuta a thovu la Yadina melamine lopangidwa pamwamba lingagwiritsidwe ntchito m'magawo ena apadera.
