I-foam material futhi inesakhiwo segridi enezinhlangothi ezintathu ezinezinga le-open-cell elingaphezu kuka-99%, elingavumeli nje kuphela amaza omsindo ukuthi aguqulwe ngempumelelo abe amandla okudlidliza wegridi futhi adliwe futhi amuncwe, okubonisa ukusebenza kahle kokufakwa komsindo, kodwa futhi ngokuphumelelayo. ivimbela ukudluliswa kokushisa kwe-convection komoya.Ngaphezu kwalokho, ukuzinza kwayo okuyingqayizivele kokushisa kwenza kube nokushisa okuhle kokushisa kanye nezakhiwo zokushisa.
Ngaphezu kwalokho, ipulasitiki ethambile ye-melamine ye-Yadina inokuminyana kuphela okungu-8-10Kg/m3, okuyenza isebenzeke kakhulu.Ingasebenza ezindaweni ezisukela emazingeni okushisa aphansi angu -200℃ kuya kumazinga okushisa aphezulu angu-200℃.Isetshenziswa kabanzi emikhakheni yokwakhiwa kwezakhiwo, izinkundla zemidlalo, okokusebenza kwefekthri, imikhiqizo ye-elekthronikhi, izimoto, amabhethri kagesi, isitimela esinesivinini esikhulu, izindiza, kanye nokuhamba.Ifaneleka ngokukhethekile ukumuncwa komsindo, ukuncishiswa komsindo, ukuncishiswa kokudlidliza, ukwahlukanisa, nokulondoloza ukushisa ngaphansi kwezimo ezivimbela umlilo nezishisa kakhulu.Ipulasitiki yegwebu le-melamine ye-Yadina nayo inamandla okuhlanza okuyisimangaliso nokumunca amanzi aphezulu kanye nokugcina umswakama, okuyenza isetshenziswe kabanzi ezindaweni ezifana nezolimo ezingenanhlabathi namabhokisi kayinki.
Igwebu elithambile le-melamine le-Yadina linobubanzi obufika ku-1300mm, ubude bufika ku-400mm, futhi lingenziwa ngokwezifiso ngobude.Ububanzi be-1300mm buhlangabezana nemfuneko yezinto eziningi zeshidi lezimboni ezinobubanzi obungu-1000mm.
Igwebu elithambile le-melamine lika-Yadina liza ngokumhlophe, okumpunga, noma eminye imibala engokwezifiso.Osayizi abahlukahlukene namaphrofayili angenziwa ngokwezifiso ngokuya ngezidingo zamakhasimende ukuze ahlangabezane nezidingo zezindawo ezahlukahlukene.
Izinto zokupakisha ezijwayelekile ezisetshenziswa ifilimu yepulasitiki ye-polyethylene.
Ngokusebenzisa igwebu le-Yadina melamine namaphrofayili, ukucubungula okulandelayo okujulile emikhakheni ehlukene kungenziwa:
1. Ukucutshungulwa komshini:
Igwebu le-Yadina melamine lingacutshungulwa libe yimikhiqizo yocezu olulodwa ngokusika nokucindezela.Ingase futhi icutshungulwe ibe yishidi kanye nezimo zejiyomethri eziyinkimbinkimbi ezingavamile ngezindlela zomshini ezifana nokubunjwa, ukusika, nokugaya, futhi indawo engaphezulu ingacutshungulwa ibe yimikhiqizo emunca umsindo emise okwe-chevron ukuze ihlangabezane nezidingo zokumunca umsindo.
2. I-Surface coating:
Ukuze ufake umbala noma uthuthukise izakhiwo zemishini, igwebu le-Yadina melamine lingagcotshwa ngaphezulu ngokufafaza, ukugoqa, nokumboza.
3. Ukuxhumana nokucwiliswa:
Ngenxa yokumelana kwayo okuhle kakhulu namakhemikhali, izinto zokunamathela ezijwayelekile ezifana ne-acrylic resin zingasetshenziswa ukuxhuma i-Yadina melamine foam.Izinamathiselo zenhlaka ezincibilikisiwe nezisebenzayo nazo zingasetshenziswa ngaphansi kokucutshungulwa ukumelana kwazo namakhemikhali.Uketshezi oluthe xaxa lungakhishwa nge-twin-screw extruder ukuze kusheshiswe inqubo yokomisa.
4. Ukucindezela okushisayo:
Amashidi egwebu le-Yadina melamine angenziwa abe ophahleni abamunca umsindo nama-rolls ngokucindezela okushisayo, kuyilapho amandla angaphezulu nawo ethuthuka.Zingahlanganiswa kalula nezinto ezifana ne-metal foil, izindwangu, nezindwangu ezingalukiwe ukuze zikhiqize uchungechunge lwemikhiqizo emunca umsindo, i-insulation, kanye ne-thermal insulation ukuze ihlangabezane nezidingo zezindawo ezahlukene nezimo zokusebenza.
5. Ukuxosha amanzi namafutha:
Ukuxosha amanzi namafutha kwegwebu le-Yadina melamine elashwe phezulu kungasetshenziswa kwezinye izinkambu ezikhethekile.
