YiniI-lubricant ye-WPC?

Isengezo sokucubungula i-WPC(ebizwa nangokuthiI-Lubricant ye-WPC, nomai-ejenti yokukhulula ye-WPC) i-lubricant enikezelwe ekukhiqizeni nasekucubunguleni izinhlanganisela ze-wood-plastic (WPC): Thuthukisa ukusebenza kokugeleza kokucubungula, uthuthukise ikhwalithi yokubukeka yemikhiqizo, uqinisekise izici ezibonakalayo zemikhiqizo, unciphise ukungqubuzana phakathi kwenhlanganisela ye-polymer nemishini yokucubungula, ukunciphisa ukugqoka kwemishini, kanye nokubunjwa kwe-extrusion kubushelelezi. Izinga leisithasiselo sokuthambisa se-WPCkunomthelela omkhulu empilweni yesevisi yesikhunta, umgqomo nesikulufu ekucutshungulweni kwepulasitiki yokhuni, umthamo wokukhiqiza we-extruder, ukusetshenziswa kwamandla enqubweni yokukhiqiza, ukuphela kwendawo yemikhiqizo kanye nokusebenza komthelela ophansi wokushisa wamaphrofayili. Futhi uma ukwengeza i-stearate kusizo lokucubungula izinkuni nge-MAH kuzowenza buthaka umphumela wokuxhumanisa we-maleic anhydride, i-crosslinking agent kanye nokusebenza kahle kwamafutha kuzoncishiswa.

Ukukhethwa kweisixazululo se-lubricant se-WPCibheka lezi zidingo ezilandelayo:

Inokuhambisana okuhle ne-resin ekushiseni okuphezulu, ingakhiqiza umphumela othile we-plasticizing, inciphise amandla okuhlangana phakathi kwama-molecule e-resin, yenza ama-molecule abe buthaka.

, ukungqubuzana phakathi komunye nomunye, kunciphisa i-viscosity encibilikayo ye-resin, kuthuthukisa ukugeleza kokuncibilika, kukhuthaze ukushelela kwezinhlayiya ze-resin.

Imikhiqizo ye-WPC ifaka phakathi izinhlelo zokusebenza eziningi, zonke lezi zizosebenzisa okokugcoba ngesikhathi sokukhiqiza ukuze uthole ikhwalithi engcono kakhulu yendawo yokuhlala, izinhlangothi, izinhlelo zokusebenza zokuvala udonga ukuze kuthuthukiswe ukusebenza kokucubungula kanye nokunikeza ikhwalithi engcono yendawo, njll.

I-lubricant ye-WPC ehamba phambili kufanele ibe nemisebenzi eminingi, inhloso ukwenza imishini yokucubungula idlale izici zokusebenza ezingcono kakhulu, ikhulise ukukhiqizwa, futhi ithuthukise ikhwalithi yemikhiqizo:

1. Ukusebenzisana kwamangqamuzana ama-polymers/ama-polymer

2, Sheshisa umphumela we-plasticizing;

3, Yehlisa ukuncibilika kwe-viscosity;

4, Yehlisa i-torque kanye nokusetshenziswa kwamandla;

5. Ukusebenzisana kwe-polymer/filler interface

6, Khuthaza ukuhlakazwa kwempushana yokhuni noma isigcwalisi sefiber yemvelo;

7, Faka isandla ekumanziseni okokugcwalisa;

8, I-polymer egcwele i-Lubricated kanye ne-interface yensimbi evuthayo noma epholile;

9, Thuthukisa impahla yokudiliza yezinto ezisebhakedeni le-extrusion kanye nendawo yokufa;

10, Nciphisa ukungqubuzana nokuguga;

11, Ukuhlinzeka ngokugcotshwa Kwangaphakathi & Kwangaphandle kwemikhiqizo ye-WPC

Kunezinhlobo eziningi ezahlukeneizinkuni zokugcoba zepulasitikinjengei-lubricant esekelwe ku-silicone SILIKE Silimer 5400, i-ethylene bis-stearamide (EBS), i-zinc stearate, ama-wax kapharafini, ne-PE oxidized. Futhi ziyinii-wpc lubricant umehluko? Isisindo samangqamuzana, umthamo, ukusebenza yizici ezinomthelela ohlukile ngokusebenza okuhlukile.Amafutha asekelwe ku-siliconeamelana kakhulu nokuguga, kanye nokushisa namakhemikhali. Futhi awanabo ubuthi futhi awashi, okuwenza abe yinketho ekahle ezinhlelweni eziningi. Izithambisi ezenziwe nge-silicone nazo zinganciphisa ukungqubuzana phakathi kwezingxenye ezihambayo, ezingasiza ukunweba impilo yama-WPC.

Kuthiwani ngomthamo we-lubricant yepulasitiki yokhuni?

Ngokuvamile, izinhlanganisela zepulasitiki zokhuni (WPC) zisebenzisa okokugcoba okuphindwe kabili kunepulasitiki evamile. Ezingxenyeni zepulasitiki zokhuni ezinomucu wokhuni ongu-50% ~ 60%, inani lokuthambisa le-HDPE esekelwe ku-4% ~ 5%, inani lokuthambisa le-PP esekelwe ku-1% ~ 2%, kanye nenani lokuthambisa le-PVC esekelwe. impahla ingu-5%~10%. Kodwa-ke, umthamo wangempela ungalungiswa ngokuya ngezindlela ezahlukahlukene nezinqubo zamabhizinisi.SILIKE silimer 5400izonikeza ukusebenza okungcono ngomthamo omncane ngo-1.5%~3%.

I-Chengdu Silike Technology Co., LTD iyinhlanganoUmkhiqizi wokugcoba wase-China WPCukuhlinzekai-silicone-based lubricant ye-WPC. Lesi sengezo se-lubricant senzelwe ukucubungula nokukhiqizwa kwe-PE WPC kanye ne-PP WPC (izinto zepulasitiki zokhuni) njenge-WPC decking, ucingo lwe-WPC, nezinye izinhlanganisela ze-WPC, njll. Ingxenye eyinhloko yalesi sixazululo se-lubricant ye-WPC i-polysiloxane eguquliwe, equkethe amaqembu asebenzayo e-polar, ukuhambisana okuhle kakhulu ne-resin kanye nempushana yokhuni, ekucubunguleni nasekukhiqizeni kungathuthukisa ukuhlakazeka kwempushana yokhuni, akuphazamisi umphumela wokuhambisana kwama-compatibilizers ohlelweni, kungathuthukisa ngempumelelo izakhiwo zemishini yomkhiqizo. Le ejenti yokukhulula yezinhlanganisela ze-WPC inikeza ukusebenza okuningi kune-ethylene bis-stearamide (EBS), i-zinc stearate, ama-wax kapharafini, ne-PE ene-oxidized, futhi lesi sithambisi singabizi kakhulu ngokuthambisa okuhle kakhulu, singathuthukisa izakhiwo zokucubungula i-matrix resin, kodwa futhi yenze. umkhiqizo bushelelezi, nikeza izinhlanganisela zakho zepulasitiki zokhuni isimo esisha.

LokhuI-lubricant ye-WPC engcono kakhuluI-Silimer 5400 inikeza izinzuzo eziningi njengoba ngezansi:

1, Thuthukisa ukucutshungulwa, unciphise i-torque ye-extruder, uthuthukise ukuhlakazeka kwesigcwalisi;

2. Nikaokokugcoba kwangaphakathi nangaphandle kwe-WPC, ukunciphisa ukusetshenziswa kwamandla futhi kwandise ukusebenza kahle kokukhiqiza;

3, Ukuhambisana okuhle nempushana yokhuni, akuthinti amandla phakathi kwama-molecule enhlanganisela yepulasitiki yokhuni futhi igcina izakhiwo zemishini ye-substrate ngokwayo;

4, Nciphisa inani le-compatibilizer, unciphise amaphutha omkhiqizo, uthuthukise ukubukeka kwemikhiqizo yepulasitiki yokhuni;

5, Ayikho imvula ngemva kokuhlolwa okubilayo, gcinaubushelelezi besikhathi eside.

Qamba i-silicone, Inika amandla inani elisha.
