Ukukhetha kahle izithasiselo kuyisici esibalulekile kokubili ekuthuthukisweni kwezakhiwo ezingokwemvelo zezinhlanganisela zokhuni-zepulasitiki (ama-WPC) kanye nasekuthuthukisweni kwezakhiwo zokucubungula. Izinkinga zokugoba, ukuqhekeka, kanye nokufaka umbala ngezinye izikhathi zivela ebusweni bezinto ezibonakalayo, futhi yilapho izithasiselo zingasiza khona. Emgqeni wokukhipha we-WPC, izithasiselo ziyadingeka ukuze kutholakale isivinini esifanele sokukhipha kanye nobuso obubushelelezi ukuze kugwenywe ukuqhekeka komphetho.
Phakathi kwezithasiselo ezahlukahlukene ezikhethiwe, izinto zokugcoba, izinto ezihlanganisayo, ama-antioxidants, izinto eziqinisa ukukhanya, kanye nezinto ezilwa nesikhunta/amagciwane zinomthelela omkhulu kwikhwalithi yezinhlanganisela zokhuni-plastiki. Ngokuphathelene nezithasiselo ezikhethekile zezinhlanganisela zokhuni-plastiki, ama-resin ahlukene e-matrix adinga ukuthuthukisa izithasiselo ezikhethekile ukuze ahlangabezane nezidingo zokusebenza komkhiqizo ohlanganisiwe noma ukusebenza kokucubungula, nokho, kunezinhlobo eziningi zezithasiselo zezinhlanganisela zokhuni-plastiki, futhi ukukhethwa kwezithasiselo ezifanele kubalulekile ekukhiqizweni kwezinhlanganisela zokhuni-plastiki.
Indima Yezithasiselo Ezihlanganisweni Zokhuni NepulasitikiIzinhlobo kanye nezinzuzo
I-ejenti yokuxhumanisa
Ama-Crosslinking agents ahlanganisa imicu yokhuni kanye ne-matrix resin ndawonye, athuthukisa amandla okuguquguquka kanye nokuqina kwezinto ezihlanganisiwe, kanye nokuthuthukisa i-modulus yokumelana nokuqhekeka kanye ne-modulus yokuguquguquka. Ama-Crosslinking agents athuthukisa futhi ukuzinza kobukhulu bezinto, amandla okushaya, izakhiwo zokuhlakazeka kokukhanya, kanye nokunciphisa ukukhukhuleka, okubaluleke kakhulu emikhiqizweni efana ne-balustrades, i-stair railings, kanye ne-guardrails. Ngezinhlanganisela zokhuni zepulasitiki ezisetshenziswa ezintweni zokuhlobisa, indima eyinhloko ye-crosslinking agent ukunciphisa ukumuncwa kwamanzi kwezinto, okungagwema ukwenzeka kokuqhekeka kokucindezeleka okubangelwa ukwanda kwemicu yokhuni ngenxa yokumuncwa kwamanzi.
I-Antioxidant
Ngemikhiqizo yokhuni lwepulasitiki, ukukhethwa kwe-antioxidant yendabuko eyinhloko yi-BHT kanye nezigaba ezimbili ze-1010. Intengo ye-BHT iphansi kancane, umphumela we-oxidation omelana nokushisa kamuva muhle, kodwa i-BHT ngokwayo ngemva kokuhlanganiswa kwe-oxidation, izokwakha i-DTNP, isakhiwo ngokwaso singumbala ophuzi, kumkhiqizo wamabala anombala, ngakho-ke ukusetshenziswa akusabalele. I-1010 hhayi kuphela emikhiqizweni yokhuni yepulasitiki kodwa kulo lonke uchungechunge lwemboni ye-polymer inezinhlobo eziningi zezicelo futhi futhi iyi-antioxidant eyinhloko enkulu kunazo zonke emhlabeni futhi esetshenziswa kakhulu.
Izinto ezilwa nesikhunta/ezilwa namagciwane
Njengamanje, ama-ejenti e-anti-mold kanye nama-antimicrobial epulasitiki enziwe ngokhuni, uhlobo lwe-boron ne-zinc, usawoti oxutshwe, umkhiqizo we-mold kanye nama-bacteria abola ngokhuni unekhono elithile lokuvimbela, kodwa futhi uzinzile kahle ekushiseni kanye nokuqina kwe-UV, ukujoyina kungathuthukisa futhi izakhiwo ezivimbela ilangabi zezinto ezibonakalayo, kodwa inani lomkhiqizo lokwengeza liphezulu, izindleko eziphezulu zokwengeza, kanye nezakhiwo zemishini zemikhiqizo yepulasitiki yokhuni zinethonya elibi; elinye ikilasi yi-arsenic-containing organic compounds, ukwakheka kwamapulasitiki kusetshenziswa kabanzi. Ngenani elincane lezithasiselo, ukumelana nesikhunta, nezinye izici, kodwa ngoba into iqukethe i-arsenic, ayifinyeleli isitifiketi se-REACH kanye ne-ROSH, ngakho-ke abakhiqizi bezinkuni zepulasitiki nabo basebenzisa okuncane.
Izinto zokugcoba zingathuthukisa izakhiwo ezingaphezulu kwezinto zokwenziwa ngokhuni ezenziwe ngepulasitiki futhi zandise umkhiqizo. Izinto zokugcoba ezivamile ezisetshenziswa ezintweni zokwenziwa ngokhuni ezenziwe ngepulasitiki yi-ethylene bisceramide (EBS), i-zinc stearate, i-paraffin wax, i-oxidized polyethylene, njll. I-EBS kanye ne-zinc stearate zisetshenziswa kabanzi ezintweni zokwenziwa ngokhuni ezenziwe ngepulasitiki ezisekelwe ku-HDPE, kodwa njengoba ukuba khona kwe-stearate kunciphisa umphumela wokuxhumanisa we-maleic anhydride, ukusebenza kahle kokubili kwezinto zokuhlanganisa kanye nezinto zokugcoba kuyancipha. Ngakho-ke, izinhlobo ezintsha zokugcoba zisathuthukiswa.
Ukusebenza Kahle Kuhlangabezana Nokusimama:Izithambisi Ezisebenza Kakhulu ze-WPC Enobungani Nemvelo！
To ukubhekana nobunzima bokugcoba okwenziwe ngokhuni nepulasitikiimakethe, i-SILIKE isungule uchungechunge lweamafutha okugcoba akhethekile ezinto ezihlanganisiwe zokhuni-plastiki (ama-WPC)
Lo mkhiqizo uyi-polymer ekhethekile ye-silicone, eyenzelwe ngokukhethekile izinto ezihlanganisiwe zokhuni-ipulasitiki. Isebenzisa amaketanga akhethekile e-polysiloxane kuma-molecule ukuze ifinyelele ukugcotshwa nokuthuthukisa ezinye izakhiwo. Inganciphisa ukungqubuzana kwangaphakathi kanye nokungqubuzana kwangaphandle kwezinto ezihlanganisiwe zokhuni-ipulasitiki, ithuthukise amandla okushelela phakathi kwezinto nezinto zokusebenza, inciphise ngempumelelo i-torque yemishini, inciphise ukusetshenziswa kwamandla, futhi ikhuphule umkhiqizo.
Okuvelele kweI-lubricant ye-SILIKE yezinto ezihlanganisiwe zokhuni nepulasitiki, uma kuqhathaniswa nezithasiselo eziphilayo ezifana nama-stearates noma ama-PE waxes, umthamo ungandiswa, Gcina izakhiwo ezinhle zemishini.
Vulaizixazululo eziluhlaza ze-HDPE/PP/PVC/ kanye nezinye izinhlanganisela zokhuni-zepulasitiki. Kusetshenziswa kabanzi efenisha, ekwakheni, ekuhlobiseni, ezimbonini zezimoto, kanye nezokuthutha.
Izinzuzo ezijwayelekile:
1) Thuthukisa ukucubungula, nciphisa i-torque ye-extruder, futhi uthuthukise ukuhlakazeka kokugcwalisa;
2) Nciphisa ukungqubuzana kwangaphakathi nangaphandle, nciphisa ukusetshenziswa kwamandla, futhi wandise ukusebenza kahle kokukhiqiza;
3) Ukuhambisana okuhle nempuphu yokhuni, akuthinti amandla phakathi kwama-molecule epulasitiki yokhuni
inhlanganisela futhi igcina izakhiwo zemishini ze-substrate ngokwayo;
4) Nciphisa inani le-compatibilizer, nciphisa amaphutha omkhiqizo, futhi uthuthukise ukubukeka kwemikhiqizo yepulasitiki yokhuni;
5) Akukho mvula ngemva kokuhlolwa kokubilisa, gcina ubushelelezi besikhathi eside.
Ngezansi kunencwajana ethiImikhiqizo yokugcoba ye-SILIKE yezinto ezihlanganisiwe zokhuni nepulasitikiongaphequlula kuzo, futhi uma udinga izinto zokugcoba ezenziwe ngokhuni-plastiki, phakamisa ukukhiqizwa kwakho kwe-Wood-Plastic Composite, ikhwalithi yokuchaza kabusha! I-SILIKE iyakwamukela uphenyo lwakho!
