Ngemva kweminyaka emi-5 yemizamo eqhubekayo, umnyango wokucwaninga nokuthuthukiswa kobuchwepheshe be-DEKAL uthuthukise uhlobo olusha lwempahla yefreyimu yesithombe i-WPC (Wood Plastic Composite-WPC) ehlanganisa kahle ipulasitiki nokhuni. Uma kuqhathaniswa nohlaka lwesithombe se-PS emakethe ekhona, lunamandla aphakeme nokuqina, umuzwa wokhuni oluqinile, kanye ne-fire retadant. Uma kuqhathaniswa nohlaka lwesithombe olugoqwe ngephepha lwe-MDF olukhona, iphethini inomphumela onamandla wezinhlangothi ezintathu, ivikela isikhutha kanye nomswakama, futhi inokusebenza okuphezulu kokuvikela imvelo, ngakho-ke asikho isidingo sokukhathazeka ngokuqukethwe kwe-formaldehyde. Uma kuqhathaniswa nohlaka lwesithombe sokhuni noma uhlaka lwesithombe olupendiwe lwe-MDF, izindleko ziphansi futhi ziyonga kakhulu. Lapho umkhiqizo usufakwe emakethe, wanconywa amakhasimende njengesizukulwane esisha semikhiqizo yefreyimu yezithombe nezinto ezintsha.
Yini i-WPC
Izinhlanganisela zokhuni-zepulasitiki (Izinhlanganisela Zokhuni-zePlastiki, i-WPC) wuhlobo olusha lwezinto eziyinhlanganisela ezithuthuke ngamandla ekhaya naphesheya eminyakeni yamuva. Imicu yokhuni ye-inorganic ixutshwa entweni entsha yokhuni. I-Inorganic wood fiber iyinhlangano eyimishini eyakhiwe izindonga zamaseli eziqinile eziqinile kanye namaseli efayibha anemigodi efana nokuqhekeka, futhi ingenye yezingxenye eziyinhloko zengxenye yokhuni. I-fiber yokhuni esetshenziswa embonini yendwangu kanye nezingubo i-viscose fiber eguqulwa kusuka ku-pulp yezinkuni ngenqubo yokukhiqiza.
Yiziphi izici zezinto ze-WPC
Isisekelo sezinhlanganisela zezinkuni-plastiki yi-polyethylene ephezulu-density kanye ne-inorganic wood fibers, enquma ukuthi inezici ezithile zepulasitiki nezinkuni.
1. Ukusebenza kahle kokucubungula
Izinhlanganisela zokhuni-zepulasitiki ziqukethe amapulasitiki nemicu, ngakho-ke zinezakhiwo zokucubungula ezifana nokhuni: zingasaha, zibethelwe futhi zonakaliswe, futhi zingaqedwa ngamathuluzi okhuni. Amandla okubamba izinzipho angcono kakhulu kunezinye izinto zokwenziwa. Izakhiwo zemishini ziphakeme kunezinto zokhuni, futhi amandla okubamba izipikili ngokuvamile izikhathi ezi-3 zokhuni kanye nezikhathi ezi-5 zamabhodi anezingqimba eziningi.
2. Ukusebenza kahle kwamandla
Izinhlanganisela zezinkuni-plastiki ziqukethe ipulasitiki, ngakho-ke zinokunwebeka okuhle. Ngaphezu kwalokho, ngenxa yokuthi iqukethe imicu futhi ixubene ngokugcwele nepulasitiki, inezici zomzimba nemishini ezilingana nokhuni oluqinile njengokumelana nokucindezela nokugoba, futhi ukuqina kwayo kungcono kakhulu kunezinto zokhuni ezivamile. Ukuqina kobuso kuphezulu, ngokuvamile izikhathi ezingu-2-5 kokhuni.
3. Ukumelana nokukhanya kwenyanga, ukumelana nokugqwala, impilo ende yesevisi
Uma kuqhathaniswa nokhuni, izinkuni-plastic materials kanye nemikhiqizo yazo imelana ne-asidi eqinile ne-alkali, amanzi nokugqwala, ayizali amagciwane, akulula ukudliwa yizinambuzane, azizalisi isikhunta, futhi zibe nokuphila isikhathi eside, okuyinto ingafinyelela eminyakeni engaphezu kwengu-50.
4. Ukusebenza okuhle kakhulu okulungiswayo
Ngokusebenzisa izithasiselo, amapulasitiki angabhekana nezinguquko ezifana ne-polymerization, ukugwebu, ukuphulukisa, nokuguqulwa, ngaleyo ndlela uguqule izici zezinto zokwakha zezinkuni-plastiki ezifana nokushuba namandla, futhi zingahlangabezana nezidingo ezikhethekile ezifana nokuvikelwa kwemvelo, ukuvinjelwa komlilo, ukumelana nomthelela, kanye nokumelana nokuguga.
5. Inokuqina kokukhanya kwe-UV kanye nempahla enemibala emihle.
6. Umthombo wezinto zokusetshenziswa
Izinto zokusetshenziswa zepulasitiki zokukhiqiza izinto ezihlanganisiwe zezinkuni-plastic ikakhulukazi i-polyethylene ephakeme kakhulu noma i-polypropylene, futhi i-inorganic wood fiber ingaba yimpushana yokhuni, i-wood fiber, kanye nenani elincane lezithasiselo nezinye izinsiza zokucubungula kudingeka zengezwe.
7. Noma yimuphi umumo nosayizi kungenziwa ngokwezifiso kuye ngezidingo.
Ukuqhathaniswa kwempahla ye-WPC nezinye izinto
Inhlanganisela ephelele yepulasitiki nezinkuni, indaba iqhathaniswa nezinkuni, kodwa futhi inezici ezifanele zepulasitiki
Uma kuqhathaniswa namafreyimu ezithombe zokhuni, ukuthungwa nokuzizwa kucishe kufane, futhi izindleko ziphansi futhi ziyonga kakhulu.
Uma iqhathaniswa nezinto ze-PS emakethe ekhona, inamandla aphakeme nokuqina, umuzwa onamandla wokhuni, futhi inobungani bemvelo futhi ivimbela ilangabi.
Uma kuqhathaniswa nohlaka lwesithombe olukhona lwe-MDF olukhona, alikwazi ukumelana nesikhunta futhi livikela umswakama, futhi linokusebenza okuphezulu kokuvikela imvelo, ngakho-ke asikho isidingo sokukhathazeka ngokuqukethwe kwe-formaldehyde.
Ukusetshenziswa kwempahla ye-WPC
Enye yezinto ezisetshenziswa kakhulu izinhlanganisela zokhuni-zepulasitiki ukufaka esikhundleni sokhuni oluqinile emikhakheni ehlukahlukene.
