KuyiniI-WPC lubricant?

Isithasiselo sokucubungula i-WPC(okubizwa nangokuthiIsithambisi se-WPCnomai-ejenti yokukhulula i-WPC) luyisithambisi esinikezelwe ekukhiqizweni nasekucutshungulweni kwezinto ezihlanganisiwe zokhuni-plastiki (i-WPC): Thuthukisa ukusebenza kokugeleza kokucubungula, sithuthukise ikhwalithi yokubukeka kwemikhiqizo, siqinisekise izakhiwo zomzimba zemikhiqizo, sinciphise ukungqubuzana phakathi kwamakhemikhali e-polymer nemishini yokucubungula, sinciphise ukuguguleka kwemishini, futhi ukubumba kwe-extrusion kubushelelezi. Ikhwalithi yeisithasiselo sokuthambisa se-WPCinethonya elikhulu empilweni yenkonzo yesikhunta, i-barrel kanye nezikulufu ekucutshungulweni kwepulasitiki yokhuni, amandla okukhiqiza e-extruder, ukusetshenziswa kwamandla enqubweni yokukhiqiza, ukuphela kobuso bemikhiqizo kanye nokusebenza komthelela ophansi kwezinga lokushisa lamaphrofayili. Futhi uma ukwengeza i-stearate ekusizeni kokucubungula izinkuni nge-MAH kuzokwenza buthaka umphumela wokuxhumanisa we-manhydride yama-maleic, ngakho-ke i-agent yokuxhumanisa kanye nokusebenza kahle kokugcoba kuzoncishiswa.

Ukukhethwa kweisixazululo sokuthambisa se-WPCicabangela lezi zimfuneko ezilandelayo:

Ihambisana kahle ne-resin ekushiseni okuphezulu, ingakhiqiza umphumela othile wokwenza ipulasitiki, inciphise amandla okuhlangana phakathi kwama-molecule ku-resin, yenze buthaka ama-molecule

, ukungqubuzana phakathi komunye nomunye, kunciphisa ukujiya kwe-resin, kuthuthukise ukugeleza kokuncibilika, kukhuthaze ukushelela kwezinhlayiya ze-resin.

Imikhiqizo ye-WPC ifaka phakathi izinhlelo zokusebenza eziningi, zonke lezi zizosebenzisa igrisi ngesikhathi sokukhiqizwa ukuze kuthuthukiswe ikhwalithi yobuso be-decking, i-sidings, izinhlelo zokusebenza ze-wall cladding ukuze kuthuthukiswe ukusebenza kokucubungula nokunikeza ikhwalithi yobuso engcono, njll.

I-WPC lubricant engcono kakhulu kufanele ibe ne-multifunctional, inhloso ukwenza imishini yokucubungula idlale izici zokusebenza ezinhle kakhulu, yandise umkhiqizo, futhi ithuthukise ikhwalithi yemikhiqizo:

1, Ukusebenzisana kwama-molecule kwama-polymer/ama-polymer

2、Sheshisa umphumela wokwenza ipulasitiki ibe nkulu;

3, Yehlisa i-viscosity encibilikayo;

4, Yehlisa i-torque kanye nokusetshenziswa kwamandla;

5, ukusebenzisana kwesixhumi esibonakalayo se-polymer/filler

6、 Khuthaza ukusabalala kwempuphu yokhuni noma i-fibre yemvelo;

7、 Faka isandla ekumanzisweni kwe-filler;

8, i-polymer egcwele amafutha kanye ne-interface yensimbi efudumele noma epholile;

9, Thuthukisa isici sokususa izinto ezisebhakedeni lokukhipha kanye nobuso bedayi;

10, Nciphisa ukungqubuzana kanye nokuguga;

11, Ukuhlinzeka ngokugcoba kwangaphakathi nangaphandle kwemikhiqizo ye-WPC

Kunezinhlobo eziningi ezahlukeneamafutha okugcoba epulasitiki okhuninjengeigrisi esekwe ku-silicone i-SILIKE Silimer 5400, i-ethylene bis-stearamide (EBS), i-zinc stearate, ama-paraffin waxes, kanye ne-oxidized PE. Futhi yiziphiumehluko wokugcoba we-wpcIsisindo sama-molecule, umthamo, ukusebenza kuyizinto ezithintayo ezahlukene ezinezici ezihlukene zokusebenza.Izithambisi ezisekelwe ku-siliconeAmelana kakhulu nokuguguleka, kanye nokushisa namakhemikhali. Azinawo ubuthi futhi azishisi, okwenza zibe ukukhetha okuhle kakhulu kwezicelo eziningi. Izithambisi ezisekelwe ku-silicone zinganciphisa nokungqubuzana phakathi kwezingxenye ezihambayo, okungasiza ekwandiseni impilo yama-WPC.

Kuyini ngesilinganiso sesithambisi sepulasitiki sokhuni?

Ngokuvamile, ama-composite epulasitiki okhuni (i-WPC) asebenzisa i-lubricant ephindwe kabili kunepulasitiki evamile. Kuma-composite epulasitiki okhuni anokuqukethwe kwefayibha yokhuni okungu-50% ~ 60%, inani le-lubricant lezinto ezisekelwe ku-HDPE lingu-4% ~ 5%, inani le-lubricant lezinto ezisekelwe ku-PP lingu-1% ~ 2%, kanti inani le-lubricant lezinto ezisekelwe ku-PVC lingu-5% ~ 10%. Kodwa-ke, umthamo wangempela ungalungiswa ngokuya ngezinhlobo ezahlukene nezinqubo zamabhizinisi.I-silime ye-SILIKE 5400kuzonikeza ukusebenza okungcono ngesilinganiso esincane esingu-1.5% ~ 3%.

I-Chengdu Silike Technology Co., LTD iyinhlanganoUmkhiqizi wokugcoba we-WPC waseShayinaukuhlinzekaigrisi esekwe ku-silicone ye-WPC. Lesi sithako sokugcoba senzelwe ngokukhethekile ukucubungula nokukhiqizwa kwe-PE WPC kanye ne-PP WPC (izinto zepulasitiki zokhuni) njenge-WPC decking, ucingo lwe-WPC, nezinye izinto ezihlanganisiwe ze-WPC, njll. Ingxenye eyinhloko yalesi sixazululo sokugcoba se-WPC yi-polysiloxane eguquliwe, equkethe amaqembu asebenzayo e-polar, ukuhambisana okuhle kakhulu ne-resin kanye ne-wood powder, enkambisweni yokucubungula nokukhiqizwa kungathuthukisa ukusabalala kwe-wood powder, akuthinti umphumela wokuhambisana wezinto ezihambisanayo ohlelweni, kungathuthukisa ngempumelelo izakhiwo zemishini zomkhiqizo. Le ejenti yokukhulula izinto ezihlanganisiwe ze-WPC inikeza ukusebenza okungaphezu kwe-ethylene bis-stearamide (EBS), i-zinc stearate, i-paraffin waxes, kanye ne-oxidized PE, futhi lokhu kugcoba kuyabiza kakhulu ngokugcoba okuhle kakhulu, kungathuthukisa izakhiwo zokucubungula i-matrix resin, kodwa futhi kwenze umkhiqizo ube bushelelezi, kunikeze izinto ezihlanganisiwe zepulasitiki zokhuni isimo esisha.

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

1, Thuthukisa ukucutshungulwa, nciphisa i-torque ye-extruder, thuthukisa ukuhlakazeka kokugcwalisa;

2, Nikezaigrisi yangaphakathi neyangaphandle ye-WPC, ukunciphisa ukusetshenziswa kwamandla nokwandisa ukusebenza kahle kokukhiqiza;

3, Ukuhambisana okuhle nempuphu yokhuni, akuthinti amandla phakathi kwama-molecule enhlanganisela yepulasitiki yokhuni futhi kugcina izakhiwo zemishini ze-substrate ngokwayo;

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

5, Akukho mvula ngemva kokuhlolwa kokubilisa, gcinaukushelela kwesikhathi eside.

Qamba i-silicone, inika amandla inani elisha.
