Yintoni iIsithambiso seWPC?

WPC processing isongezo(ekwabizwa ngokubaIsithambiso seWPC, okanyeiarhente yokukhulula yeWPC) sisithambiso esizinikezelwe kwimveliso kunye nokusetyenzwa kwee-composites zeplastic-plastic (WPC): Ukuphucula ukuhamba komsebenzi, ukuphucula umgangatho wembonakalo yeemveliso, ukuqinisekisa iimpawu ezibonakalayo zeemveliso, ukunciphisa ingxabano phakathi kweekhompawundi zepolymer kunye noomatshini bokulungisa, ukunciphisa ukunxiba izixhobo, kunye nokubumba extrusion agudileyo.Umgangatho wei-lubricant additive for WPCinempembelelo enkulu kubomi benkonzo yokungunda, umphanda kunye jija kwiplasitiki yokwenziwa komthi, umthamo wemveliso ye-extruder, ukusetyenziswa kwamandla kwinkqubo yokuvelisa, ukugqiba komphezulu weemveliso kunye nokusebenza kwefuthe eliphantsi lobushushu beeprofayili.Kwaye ukuba ukongeza i-stearate kuncedo lokulungisa iinkuni nge-MAH kuya kwenza buthathaka isiphumo sokuwela i-anhydride ye-maleic, i-agent ye-crosslinking kunye nokusebenza kakuhle kwe-lubricant kuya kuncitshiswa.

Ukhetho lweisisombululo se-lubricant seWPCiqwalasela ezi mfuno zilandelayo:

Inokuhambelana kakuhle kunye ne-resin kwiqondo lokushisa eliphezulu, inokuvelisa umphumo othile weplastiki, ukunciphisa amandla okubambisana phakathi kweemolekyuli kwi-resin, buthathaka iimolekyuli.

, ukungqubuzana phakathi komnye nomnye, ukunciphisa i-viscosity enyibilikayo ye-resin, ukuphucula ukuhamba kwe-melting, ukukhuthaza ukutyibilika kwee-resin particles.

Iimveliso ze-WPC zibandakanya izicelo ezininzi, ezi zonke ziya kusebenzisa i-lubricant ngexesha lemveliso yomgangatho ongcono womphezulu wokuhombisa, ii-sidings, izicelo zokugquma eludongeni ukuphucula ukusebenza kokusebenza kunye nokunika umgangatho ongcono womphezulu, njl.

Best WPC lubricant kufuneka multi-esebenzayo, injongo kukwenza isixhobo processing ukudlala eyona mpawu yokusebenza, ukwandisa imveliso, nokuphucula umgangatho weemveliso:

1. Ukusebenzisana kweemolekyuli zeepolymers / iipolymers

2, Ukukhawulezisa isiphumo plasticizing;

3, Nciphisa ukunyibilika viscosity;

4, Ukunciphisa i-torque kunye nokusetyenziswa kwamandla;

I-5, i-Polymer / i-filler interface yentsebenziswano

6, Khuthaza ukusasazwa komgubo womthi okanye isigcwalisi sefiber yendalo;

7. Yiba negalelo ekufunxeni kwesihluzi;

8, i-polymer egcwele i-Lubricated kunye ne-interface yensimbi eshushu okanye epholileyo;

9, Ukuphucula ipropathi yokudiliza yezinto kwibhakethi ye-extrusion kunye nomphezulu wokufa;

10, Nciphisa ingxabano kunye nokuguga;

11, Ukubonelela ngaPhakathi kunye nokuthambisa kwaNgaphandle kwiimveliso zeWPC

Kukho ezininzi ezahlukeneyoiinkuni zeplastiki zokuthambisanjengei-silicone-based lubricant SILIKE Silimer 5400, i-ethylene bis-stearamide (EBS), i-zinc stearate, i-parafini wax, kunye ne-PE oxidized.Kwaye yintoni nai-wpc lubricants umahluko?Ubunzima bemolekyuli, idosi, iintsebenzo zizinto ezahlukeneyo ezineempembelelo ezineentsebenzo ezahlukeneyo.Izithambiso ezisekelwe kwi-siliconezixhathisa kakhulu ukunxiba nokukrazuka, kunye nobushushu kunye neekhemikhali.Kananjalo ayinayo ityhefu kwaye ayinakutsha, ibenza ibe lolona khetho lufanelekileyo kwizicelo ezininzi.Izithambisi ezisekwe kwi-silicone zinokunciphisa ukukhuhlana phakathi kweendawo ezihambayo, ezinokunceda ukwandisa ubomi bee-WPCs.

Yintoni malunga nethamo lezinto zokuthambisa zeplastiki zomthi?

Xa sithetha ngokubanzi, iicomposites zeplasitiki zomthi (WPC) zisebenzisa i-lubricant ephindwe kabini kuneeplastiki eziqhelekileyo.Kwimihlanganisela yeplastiki yeplasitiki enomxholo wefayibha yomthi we-50% ~ 60%, isixa se-lubricant semathiriyeli esekwe kwi-HDPE yi-4% ~5%, isixa se-lubricant sezinto ezisekelwe kwi-PP yi-1% ~ 2%, kunye nesixa se-lubricant se-PVC esekwe. imathiriyeli yi-5% ~ 10%.Nangona kunjalo, idosi yokwenyani inokulungelelaniswa ngokweendlela ezahlukeneyo kunye neenkqubo zamashishini.SILIKE silimer 5400iya kunika imisebenzi engcono kunye nedosi encinci kunye ne-1.5% ~ 3%.

I-Chengdu Silike Technology Co.,LTD iChina WPC umenzi wokuthambisaukunikezai-silicone-based lubricant ye-WPC.Esi songezo se-lubricant siphuhliswe ngokukodwa ukusetyenzwa kunye nokuveliswa kwe-PE WPC kunye ne-PP WPC (izinto zeplastiki zomthi) ezifana ne-WPC yokuhombisa, ucingo lwe-WPC, kunye nezinye ii-composites ze-WPC, njl njl. equlethe amaqela asebenzayo e-polar, ukuhambelana okugqwesileyo kunye ne-resin kunye nomgubo womthi, kwinkqubo yokucubungula kunye nemveliso inokuphucula ukusasazwa komgubo wokhuni, ayichaphazeli umphumo wokuhambelana kwee-compatibilizers kwinkqubo, inokuphucula ngokufanelekileyo iimpawu zomatshini zemveliso.Le arhente yokukhupha i-WPC composite inika ukusebenza okuninzi kune-ethylene bis-stearamide (EBS), i-zinc stearate, iparafini waxes, kunye ne-oxidized PE, kwaye esi sithambiso sisebenza ngexabiso eliphantsi kunye nokuthambisa okugqwesileyo, kunokuphucula iimpawu zokusetyenzwa kweresin ye-matrix, kodwa kwakhona imveliso igudileyo, nika imidibaniso yakho yeplastiki eyenziwe ngomthi ibe yimo entsha.

OkuEyona lubricant yeWPCI-Silimer 5400 inika izibonelelo ezininzi ngolu hlobo lungezantsi:

I-1, Ukuphucula ukusetyenzwa, ukunciphisa i-torque ye-extruder, phucula ukusasazwa kokugcwalisa;

2, Nikayangaphakathi & yangaphandle yokuthambisa yeWPC, ukunciphisa ukusetyenziswa kwamandla kunye nokwandisa ukusebenza kakuhle kwemveliso;

I-3, ukuhambelana kakuhle kunye nomgubo womthi, awuchaphazeli amandla phakathi kweemolekyuli zeplastiki yeplanga edibeneyo kwaye igcina iimpawu zomatshini ze-substrate ngokwayo;

4, Nciphisa isixa comppatibilizer, ukunciphisa iziphene imveliso, ukuphucula inkangeleko yeemveliso zeplastiki iinkuni;

5, Akukho mvula emva kovavanyo lokubilisa, gcinaubude bexesha elide.

Ukuvuselela i-silicone, Ukuxhobisa ixabiso elitsha.
