Ukuphakanyiswa KweSibhalo SeWPC Ngokuphakanyiswa Kwesithunzi Nakwakubonakaliswa Kwezinkampani Zokuhlela Umbala
Ukugqibela kwesithunzi kuchazwa ngokuzimisa isibhalo seWPC. Ngaphandle kwezinto zokushisa, zonke izinhloso zokushisa zasezinsukwini zinamathuba amaningi okukhula kwezinkampani zokuvula i-UV ukuze ukhule umbala.
Ukusebenza Kwezinkampani Zokuvula I-UV Nakwezinkampani Zokuvula I-HALS
Ngaphandle kwezinye izinhloso, iWPC isebenza nezinkampani zokuvula i-UV nakwezinkampani zokuvula i-HALS okuzoba kuyibeka i-UV njengekhanda. Izinkampani zokuvula i-HALS zisebenza ukuhlanza amasiko amahleli nakukhulisa ukungabonakali kwezinhloso zokugqibela. Le ndlela yokusebenza iyakukhulisa ukukhula kwezinye izinye ngaphezu kwe-80% nakukhumbula umbala nokubonakaliswa kwezinhloso.
Imibuzo Yokuhlinzeka Kwamabala Nokuphambana Kwezinhlobo
Ukufade kwamabala kugcinwa ngokukhulula kwe-titanium dioxide kunye ne-carbon black. Lokhu kuyisifundo sokuthi i-carbon black inakho ukuthatha izithombe zezulu. Lokhu kuyisifundo sokugcina ukufade kwamabala futhi kuyisifundo sokubhekana nokufade kwamabala ngokuphambana kwezinhlobo zezinkampani. I-nitrogen, ngaphandle kwezinye izinkampani eziqondile kwe-WPC, inakho ukugcina amabala kusukela ku-5 iminyaka, futhi le sistimu iyinhliziyo yokugcina amabala. Ngaphezu kwalokho, konke okufadile kwezinhlobo zezinkampani zemithi kugcinwa ngokuphambana kokufade kwamabala ngokwesibonelo sokuphambana kwezinkampani.

Izinkambo zokubeka kwe-WPC ziyajabuliswa ngokuthi zinomthwalo wokuguqula okuhle ngokwakho kwezinkambo zokugcina. Izinkambo zemithi zihlukwe kabusha ematrichini we-thermoplastic polymer. Isiphumo sokugcina oku kukuthi imatrichi yepolymer iyahlukana, futhi izindlela zokufaka umsindo zihlukwe. Isiphumo sokugcina oku kukuthi imatrichi yepolymer iyahlukana futhi izindlela zokufaka umsindo zihlukwe. Emindeni yezinhlangano, izinhlangano zama-WPC zizojabuliswa ngokuthi zingaphansi kwe-0.5% kuya kuma-3–8% yokuguqula kwemithi, ukuguqula kwe-linea kwe-negative 0.5% emva kwezinsuku ezi-48 zokuhluka emsindweni. Ngazo zonke izinsuku ezi-48, izinhlangano zemithi, izimboni ziyi-24–10% yokuguqula.
Ukuguqula Kwesikhathi Sokushisa: Indlela Okuyisikhalo Se-Thermoplastic Sivumela Ukungafani
Amabindela athempolastiki kwe-WPC Decking ayathumela umphumela wokubheka okunconywa uma izintemperatura zihlukana. Amabindela akhanyisa futhi abulawa xa izintemperatura zihlukana, kodwa amabindela athempolastiki ayathatha isibonelo sezintemperatura futhi, ngakho-ke isibonelo sezintemperatura kanye nesibonelo seziqukitho. Lokhu ngu-ziqukitho lokugcina futhi isibonelo seziqukitho yomkhombiso wamandla kusuka emhlabeni futhi isibonelo seziqukitho yomkhombiso awasekhiyiswe kusuka kwemhlabeni. Umphumela ngu-ziqukitho lokugcina, okuyiqinisekiswa, futhi ukuphula kwezinhlobo zemhlabeni akhulwa emhlabeni. Umphumela ngu-khulula kwemhlabeni. Umphumela wokhulula kukhulula kwezinhlobo zemhlabeni futhi umphumela wokhulula ngu-
Isiphakathi Sokuvikela WPC Decking Isikhathi Somhlabeni
Ukuhlanza Kwamafuta 0.5% 3%–8%
Ukuguqula Kwesintemperatura 2% 5%–12%
Ukuvikela Kweziqukitho Kubalulekile (ukuthatha kwe-polymer) Kuncane (ukubulawa kwe-fiber)
Ukuvikela Kweprosesi Yokuwasha WPC Decking
Ukubonakala Kwemizamo Yezinto Ezibalulekile Nokuziphatha Kwemilabhoratori
Ukuziqonda kwe-ASTM D6662 vs. Ukuziqonda Okuphakathi Kwezinsuku Eziningi Ngokwesibonelo
Ukuziqonda kwe-EXT (ukuziqonda kwelaboratori ekubaseni kwe-ASTM D6662) kuyabonisa ukuthi kufana nezinsuku eziningi zokugqamisa, futhi ukuziqonda kususwa ngokushisayo, ukuthi kususwa ngokushisayo kwezinsuku ezingaphezu kwezingu-2000 zokubuka kwe-UV, umsindo, nokuguqula kwesikhathi sokushisa nokuchitha. Amaphenyo ayasho ukuthi akukho kungaphezu kwe-3% yokuguqula, futhi ukuguqula kwembala kuncane kakhulu (ΔE < 5). Amaphenyo emkhaya ashiywe amadoda abonisa ukuthi izihlalo ziyasebenza kahle kanye noma kuzinhlaka ezinkulu, ngaphandle kokuguqula kancane. Akukho kungaphezu kwe-0.5% yomthi wasekuphambeni ukuthi ubhalela umsindo ngaphandle kokuthi kubhalela kungaphezu kwe-15%–20% yezihlalo zasekuphambeni. Lokhu okuguqulwa kucacisa ukuthi ukusebenza kwezihlalo zomthi ne-WPC kuhlanganisa nokuziqonda kwemkhaya, futhi ukubhalela kancane kwezihlalo.
Izinkampani Zokugcina Zokugcina Zizocinga Izihlalo Zomthi Ne-WPC
Izihlalo zomthi ne-WPC zisebenzisa izinkampani zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokugcina zokug......
- Izithako zokuxhuma zinikeza ukuhlanganisa ezingeni lezinhlayiyana phakathi kwezintambo zokhuni nama-polymer matrices. Izithako zokuxhuma zinciphisa ukumuncwa komswakama ngo-30% kuya ku-40% uma kuqhathaniswa nezinguqulo zokuqala.
- Ama-Hindred Amine Light Stabilizers (HALS) avimbela ama-radicals akhululekile akhiwa yizingozi ze-UV ezindaweni.
- Isizukulwane esilandelayo sezithasiselo sivimbela ukufakwa kwe-oxide okushisayo futhi sigcina ukuqina emazingeni okushisa angaphandle aphansi njengo-20 °C.
- Izithako zokugcwalisa izakhi zamaminerali ezisezingeni le-nanoscale zikhuthaza ukwanda nokuncishiswa kokushisa kwezingqimba ze-WPC ezimweni zezulu ezimbi kakhulu.
I-ASTM D6662 yokwehla kwesimo sezulu okusheshayo. isebenza njengobufakazi baselebhu bokuqina kwezithasiselo zesizukulwane esilandelayo. Izithasiselo zesizukulwane esilandelayo ziyakwazi ukugcina amandla okugoba angaphezu kuka-90% we-WPC decking ngemuva kwamahora angu-5,000 okuchayeka ezintweni. Intuthuko kwezesayensi yezinto ezibonakalayo inikeza isiqinisekiso sokumelana nokufiphala nokuqina kobukhulu esifinyelela eminyakeni engaphezu kwengu-25.
Imibuzo Evame Ukubuzwa
I-UV iyivimbela kanjani i-WPC decking?
I-ultraviolet (UV) HAsl kanye nama-UV absorbers asebenza ukuvimbela ukuvuza nokulimala kwe-UV ngokuhlasela ama-radicals akhululekile nokucindezela ukuguguleka kwemiphezulu.
Yini enikeza ukuzinza kokushisa kwe-WPC?
i-fiber-polymer matrix ivimbela ukumuncwa komswakama nokugcinwa ngaphansi kuka-1% futhi ivimbela ukungazinzi kobukhulu ngenxa yezimo zemvelo.
Ingabe ukufakwa kwe-WPC kuyahambisana nezindawo ezinezimo ezimbi kakhulu?
Yebo, izithasiselo zesizukulwane esilandelayo ezinamafomu athuthukile ziqinisekisa ukuthi uphahla lwe-WPC lugcina isakhiwo salo singaphazanyiswa ama-UV, umswakama nokujikeleza kokushisa okwedlulele amashumi eminyaka.
Umbala we-WPC uyohlala isikhathi esingakanani uma usuke usemkhathini welanga?
Ngokuhlunga kwesibuko kanye nama-pigment azinzile, ukufiphala kombala we-WPC decking kuvame ukungahlukaniseki (≤0.5 ΔE / ngonyaka).
