Ukukhetha okufanele kwezithasiselo kuyisici esibalulekile kokubili ekuthuthukisweni kwezakhiwo ze-wood-plastic composite (WPCs) kanye nasekuthuthukisweni kwezakhiwo zokucubungula. Izinkinga zokungqubuzana, ukuqhekeka, kanye nokungcolisa ngezinye izikhathi zivela ebusweni bento, futhi kulapho izithasiselo zingasiza khona. Emgqeni we-extrusion wama-WPC, izithasiselo ziyadingeka ukuze kutholwe isivinini esilungile sokukhipha kanye nendawo ebushelelezi ukugwema ukuqhekeka konqenqema.
Phakathi kwezithasiselo ezihlukahlukene ezikhethiwe, ama-lubricant, ama-cross-linking agents, ama-antioxidants, ama-stabilizers okukhanya, kanye nama-anti-mold / anti-bacterial agents anomthelela omkhulu kakhulu kwikhwalithi yezinhlanganisela zezinkuni-plastiki. Ngokuqondene nezithasiselo ezikhethekile zezinhlanganisela zezinkuni-plastic, ama-resin ahlukene e-matrix adinga ukuthuthukisa izithasiselo ezikhethekile ukuze ahlangabezane nezidingo zokusebenza komkhiqizo oyinhlanganisela noma ukusebenza kokucubungula, noma kunjalo, kunezinhlobonhlobo zezithasiselo zezinhlanganisela zokhuni-plastic, kanye nokukhethwa izithasiselo ezifanele zibalulekile ekukhiqizeni izinhlanganisela zokhuni-zepulasitiki.
Indima Yezithasiselo Ezihlanganisweni Zokhuni-Plastiki: Izinhlobo Nezinzuzo
I-ejenti ye-Crosslinking
Ama-Crosslinking agents abopha imicu yokhuni kanye ne-matrix resin ndawonye, ethuthukisa amandla aguquguqukayo kanye nokuqina kwento eyinhlanganisela, kanye nokwenza ngcono imodulus yokumelana nokuqhekeka kanye nemodulus yokunwebeka. Ama-agent e-Crosslinking aphinde athuthukise ukuzinza kwe-dimensional kwento esebenzayo, amandla okushayisana, izici zokusabalalisa ukukhanya, nokunciphisa ukukhasa, okubaluleke kakhulu emikhiqizweni efana nama-balustrade, ama-railings ezitebhisini, nama- guardrails. Ezingxenyeni zokhuni zepulasitiki ezisetshenziselwa izinto zokuhlobisa, indima eyinhloko ye-agent ye-crosslinking ukunciphisa ukumuncwa kwamanzi kwento, engagwema ukuvela kokuqhekeka kwengcindezi okubangelwa ukunwetshwa kwemicu yezinkuni ngenxa yokumuncwa kwamanzi.
I-Antioxidant
Ngemikhiqizo yezinkuni zepulasitiki, ukukhethwa kwendabuko okuyinhloko kwe-antioxidant yi-BHT kanye ne-1010 izigaba ezimbili. Intengo ye-BHT iphansi kancane, umphumela we-oxidation wakamuva we-oxidation muhle, kodwa i-BHT ngokwayo ngemva kwe-oxidation ihlangene, izokwakha i-DTNP, isakhiwo ngokwaso singumbala ophuzi, emkhiqizweni wamabala anemibala, ngakho-ke isicelo asisakazwa kabanzi. I-1010 hhayi emikhiqizweni yezinkuni zepulasitiki kuphela kodwa kuwo wonke uchungechunge lwemboni ye-polymer inezinhlobonhlobo zezinhlelo zokusebenza futhi iphinde ibe yi-antioxidant eyinhloko enkulu kunazo zonke futhi esetshenziswa kakhulu emhlabeni.
Ama-anti-mold/anti-bacterial agents
Okwamanje, izinkuni plastic anti-isikhunta kanye ejenti elwa namagciwane ekilasini boron kanye zinc usawoti exutshwe, umkhiqizo isikhunta kanye amagciwane izinkuni-rotting babe nekhono elithile inhibitory, kodwa futhi has ukuzinza okuhle ezishisayo kanye UV ukuzinza, ukujoyina kungaba ngcono izakhiwo ezivimbela ilangabi lezinto ezibonakalayo, kodwa inani lesengezo somkhiqizo liphezulu, izindleko eziphezulu zokwengeza, futhi izakhiwo zemishini yemikhiqizo yezinkuni zepulasitiki zinethonya elibi; elinye ikilasi yizinhlanganisela eziphilayo eziqukethe i-arsenic, ukwakheka kwamapulasitiki asetshenziswa kabanzi. Ngenani elincane lezithasiselo, ukumelana nesikhunta, nezinye izici, kodwa ngenxa yokuthi into iqukethe i-arsenic, hhayi kuze kufike ku-REACH kanye nesitifiketi se-ROSH, ngakho-ke abakhiqizi bezinkuni zepulasitiki basebenzisa kancane.
Izinto zokugcoba zingathuthukisa izakhiwo ezingaphezulu kwezinhlanganisela zokhuni ezenziwe ngepulasitiki futhi andise umkhiqizo. Izithambisi ezijwayelekile ezisetshenziswa ezihlanganisweni zokhuni lwepulasitiki i-ethylene bisceramide (EBS), i-zinc stearate, i-parafini wax, i-polyethylene ene-oxidized, njll. I-EBS ne-zinc stearate asetshenziswa kakhulu kuzinhlanganisela zokhuni zepulasitiki ezisekelwe ku-HDPE, kodwa njengoba ukuba khona kwe-stearate kwenza kube buthaka isiphambano- ukuxhumanisa umthelela we-anhydride yamaleic, ukusebenza kahle kwakho kokubili ama-agent axhumanisa izinto eziphambanayo kanye nezinto zokugcoba kuncipha. Ngakho-ke, izinhlobo eziningi ezintsha zokuthambisa zisathuthukiswa.
Ukusebenza kahle kuhlangabezana nokusimama:Izithambisi Ezisebenza Kakhulu Ze-Eco-Friendly WPC!
To ukubhekana nosizi lwezithambisi zezinkuni-plastiki eziyinhlanganiselaemakethe, i-SILIKE isungule uchungechunge lweokothambisa okukhethekile kwezinhlanganisela zokhuni-plastic (WPCs)
Lo mkhiqizo uyi-polymer ekhethekile ye-silicone, eyenzelwe ngokukhethekile izinto ezihlanganisiwe zezinkuni-plastiki. Isebenzisa amaketanga akhethekile e-polysiloxane kuma-molecule ukuze kuzuzwe ukugcotshwa nokuthuthukisa ezinye izakhiwo. Inganciphisa ukungqubuzana kwangaphakathi kanye nokungqubuzana kwangaphandle kwezinto eziyinhlanganisela yokhuni-yepulasitiki, ithuthukise umthamo wokushelela phakathi kwezinto nezinto zokusebenza, yehlise ngempumelelo i-torque yemishini, inciphise ukusetshenziswa kwamandla, futhi ikhulise ukukhiqiza.
Okugqamile kweI-lubricant ka-SILIKE yezinhlanganisela zokhuni nepulasitiki, uma kuqhathaniswa nezithasiselo eziphilayo ezifana ne-stearate noma ama-wax e-PE, ukuphuma kungandiswa, Gcina izakhiwo ezinhle zemishini.
Vula aizixazululo eziluhlaza ze-HDPE/PP/PVC/ nezinye izinhlanganisela zokhuni-zepulasitiki. Isetshenziswa kakhulu kwifenisha, ukwakha, ukuhlobisa, izimboni zezimoto, nezokuthutha.
Izinzuzo ezijwayelekile:
1) Thuthukisa ukucutshungulwa, unciphise i-torque ye-extruder, futhi uthuthukise ukuhlakazeka kwesigcwalisi;
2) Yehlisa ukungqubuzana kwangaphakathi nangaphandle, yehlisa ukusetshenziswa kwamandla, futhi yandise ukusebenza kahle kokukhiqiza;
3) Ukuhambisana okuhle nempushana yokhuni, akuthinti amandla phakathi kwama-molecule epulasitiki yokhuni
inhlanganisela futhi igcina izakhiwo zemishini ye-substrate ngokwayo;
4) Nciphisa inani le-compatibilizer, unciphise amaphutha omkhiqizo, futhi uthuthukise ukubukeka kwemikhiqizo yepulasitiki yokhuni;
5) Ayikho imvula ngemva kokuhlolwa okubilayo, gcina ubushelelezi besikhathi eside.
Ngezansi kunencwajana ethiImikhiqizo ka-SILIKE yokuthambisa yezinhlanganisela zokhuni nepulasitikiongakwazi ukuphequlula kukho, futhi uma udinga izinto zokugcoba ngokhuni-zepulasitiki, Elevate Your Wood-Plastic Composite Production，Redefining Quality！ SILIKE wamukela uphenyo lwakho!
