Umkhiqizo

I-Wood-plastic composite (WPC) iyinto ehlanganisiwe eyenziwe ngepulasitiki njenge-matrix kanye nokhuni njengokugcwalisa, Njengezinye izinto ezihlanganisiwe, izinto ezihlanganisiwe zigcinwa zisesimweni sazo sokuqala futhi zihlanganiswa ukuze kutholakale izinto ezintsha ezihlanganisiwe ezinezakhiwo ezifanele zemishini nezomzimba kanye nezindleko eziphansi. Yakhiwa ngamapulangwe noma ngesimo semishayo engasetshenziswa ezinhlotsheni eziningi ezifana nezitezi zangaphandle, izindonga, amabhentshi epaki, amalineni eminyango yemoto, izihlalo zemoto, uthango, ozimele bomnyango namafasitela, izakhiwo zamapuleti ezinkuni, kanye nefenisha yangaphakathi. Ngaphezu kwalokho, zibonise izinhlelo zokusebenza ezithembisayo njengamaphaneli okushisa nawokushisisa umsindo.
Kodwa-ke, njenganoma iyiphi enye into, ama-WPC adinga ukugcotshwa okufanele ukuqinisekisa ukusebenza kahle kanye nobude besikhathi. Izithasiselo ezifanele zokugcotshwa zingasiza ekuvikeleni ama-WPC ekugugeni nasekudabukeni, ukunciphisa ukungqubuzana, kanye nokuthuthukisa ukusebenza kwawo jikelele.

Uma ukhetha izithasiselo zokugcoba zama-WPC, kubalulekile ukucabangela uhlobo lokusetshenziswa kanye nendawo lapho ama-WPC azosetshenziswa khona. Isibonelo, uma ama-WPC ezovezwa emazingeni okushisa aphezulu noma umswakama, khona-ke i-lubricant ene-viscosity index ephezulu ingadingeka. Ngaphezu kwalokho, uma ama-WPC ezosetshenziswa kuhlelo oludinga ukugcoba njalo, khona-ke i-lubricant enempilo yenkonzo ende ingadingeka.

Ama-WPC angasebenzisa izinto zokugcoba ezijwayelekile zama-polyolefin kanye ne-PVC, njenge-ethylene bis-stearamide (EBS), i-zinc stearate, ama-paraffin waxes, kanye ne-oxidized PE. Ngaphezu kwalokho, izinto zokugcoba ezisekelwe ku-silicone nazo zivame ukusetshenziswa kuma-WPC.I-SiliconeIzithambisi ezisekelwe kuzo zimelana kakhulu nokuguguleka, kanye nokushisa namakhemikhali. Futhi azinabo ubuthi futhi azishi, okwenza zibe ukukhetha okuhle kakhulu kwezicelo eziningi.I-SiliconeIzithambisi ezisekelwe kuzo zinganciphisa ukungqubuzana phakathi kwezingxenye ezihambayo, okungasiza ekwandiseni impilo yama-WPC.

Isingeniso Sokugcoba sama-WPC

Lesi sixazululo se-lubricant Additives sama-WPC senzelwe ngokukhethekile ukukhiqiza izinto ezihlanganisiwe zokhuni i-PE kanye ne-PP WPC (izinto zokwakha zepulasitiki zokhuni).
Ingxenye eyinhloko yalo mkhiqizo yi-polysiloxane eguquliwe, equkethe amaqembu asebenzayo e-polar, ukuhambisana okuhle kakhulu ne-resin kanye ne-wood powder, enqubweni yokucubungula nokukhiqizwa kungathuthukisa ukusabalala kwe-wood powder, futhi akuthinti umphumela wokuhambisana we-compatibilizers ohlelweni, kungathuthukisa ngempumelelo izakhiwo zemishini zomkhiqizo. Izithasiselo Ezintsha Zokugcoba ze-SILIMER 5322 ze-Wood Plastic Composites ezinezindleko ezifanele, umphumela omuhle kakhulu wokugcoba, zingathuthukisa izakhiwo zokucubungula i-matrix resin, kodwa futhi zingenza umkhiqizo ube bushelelezi. Kungcono kune-ethylene bis-stearamide (EBS), i-zinc stearate, ama-paraffin waxes, kanye ne-oxidized PE.

Iphothifoliyo Yezixazululo ze-WPC:

1. Thuthukisa ukucubungula, wehlise i-torque ye-extruder
2. Nciphisa ukungqubuzana kwangaphakathi nangaphandle
3. Gcina izakhiwo ezinhle zemishini
4. Ukumelana okukhulu kokuklwebheka/umthelela
5. Izakhiwo ezinhle zokungathandi amanzi,
6. Ukumelana nomswakama okwandisiwe
7. Ukumelana namabala
8. Ukuzinza okuthuthukisiwe
Isetshenziswa kanjani
Kuphakanyiswa amazinga okwengeza aphakathi kuka-1 ~ 5%. Ingasetshenziswa ezinqubweni zokuxuba ezincibilikisiwe zakudala njengezikhumuli ze-Single / Twin screw, ukubumba nge-injection, kanye nokudla okuseceleni. Kunconywa ukuxuba okungokoqobo nama-pellet e-polymer ahlanzekile.

Ezokuthutha Nokugcina Izinto
Lesi sithako sokucubungula i-WPC singathuthwa njengekhemikhali engeyona ingozi. Kunconywa ukuthi sigcinwe endaweni eyomile nepholile enezinga lokushisa lokugcina elingaphansi kuka-40 ° C ukuze kugwenywe ukuhlangana. Iphakethe kumele livalwe kahle ngemva kokusetshenziswa ngakunye ukuvimbela umkhiqizo ukuthi ungathinteki umswakama.

Iphakheji kanye nesikhathi sokuphila kweshelufu
Iphakheji ejwayelekile yisikhwama sephepha esenziwe ngezandla esinesikhwama sangaphakathi se-PE esinesisindo esingu-25kg. Izici zokuqala zihlala zinjalo izinyanga ezingu-24 kusukela ngosuku lokukhiqiza uma zigcinwe endaweni yokugcina enconywayo.
