Ukuphinda Kusetshenziswe Izikhwama Ezilukiwe Ze-PP

1. Ukubuka Konke Ngokusebenzisa Kabusha Izikhwama Ezilukiwe Ze-PP Ezilahliwe

Njengoba kukhula ngokushesha ukusetshenziswa kwezikhwama ezilukiwe ze-polypropylene (PP), inani lezikhwama zemfucuza liye landa. Isikhwama Esilukiwe se-PpI-s manje iyindlela ewusizo nenethonya yokwenzanciphisa izindleko zezinto zokusetshenziswa, vikela imvelo, futhi ukwandisa ukusetshenziswa kwezinsiza.

Imfucuza ye-PP engasetshenziswa kabusha kumele ibe ipulasitiki yohlobo olulodwa, engenalo ukungcola, isihlabathi, nezinye izinto ezingcolisayo. Ngaphezu kwalokho, inkomba yayo yokugeleza kokuncibilika (i-MFI) kufanele iwele ngaphakathi kobubanzi obufanele ukuqinisekisa ukusetshenziswa kabusha okuphumelelayo.

Imithombo eyinhloko yezinto ze-PP ezingaphinde zisetshenziswe ihlanganisa:

• Izinto ezilahliwe zokukhiqiza ezivela Isikhwama Esilukiwe se-Pp ukukhiqiza

• Kusetshenzisiwe Isikhwama Esilukiwe se-Ppnjengomanyolo, ukudla, kanye nezikhwama zikasawoti

2. Izindlela Eziyinhloko Zokusebenzisa Kabusha

2.1 Ukuncibilika kwe-Melt Granulation

Ukuncibilikisa imfucuza kuhilela ukuhlunga nokugeza izinto ezilahliwe, kulandelwe ukomisa, ukusika, ukuhlanganisa imfucuza, kanye nokupakishwa. Le ndlela iguqula imfucuza ngempumelelo ibe ama-pellet angasetshenziswa kabusha.

2.2 Ukwengezwa kwe-Granulation

I-extrusion granulation iyindlela evame ukusetshenziswa ezindaweni zezimboni. Ihlanganisa ukuhlunga, ukuwasha, ukomisa, ukusika, ukukhipha okufudunyeziwe, ukupholisa, kanye nokufaka i-pelletizing. Ukuqinisekisa ubumsulwa, izihlungi ezifana nezikrini ze-mesh ezingu-80-120 zisetshenziselwa ukususa ukungcola ngesikhathi sokukhipha.

Ukulawulwa kwezinga lokushisa phakathi nale nqubo kubalulekile. Izinga lokushisa eliphakeme kakhulu lingabangela ukuguga nokushintsha kombala, kanti izinga eliphansi kakhulu lingaholela ekufakweni kwepulasitiki okungekuhle kanye nomphumela ongazinzile.

3. Ukusetshenziswa Kwezinto Ezisetshenziswe Kabusha kanye Nokusebenza Komkhiqizo

Izinto ze-PP eziphinde zasetshenziswa ziyadlula ngokungenakugwenywa ukuguga kokushisa kanye ne-UV, okungalimaza ukusebenza kwemishini. Ngakho-ke, izinto eziphinde zasetshenziswa zodwa ngokuvamile zinqunyelwe emijikelezweni yokusetshenziswa kabusha.

Ukuze kugcinwe ikhwalithi yomkhiqizo ngenkathi kusizakala ngokonga izindleko, i-PP ephinde yasetshenziswa ivame ukusetshenziswa. ixutshwe ne-resin emsulwaUmkhuba wemboni uvame ukusebenzisa cishe u-40% wezinto eziphinde zasetshenziswa, ezilungiswa ngokusekelwe kwikhwalithi yezinto ezingavuthiwe kanye nezidingo zomkhiqizo.

Okuqukethwe okuphezulu okuphinde kwasetshenziswa kunganciphisa amandla okubamba kanye nobude, ngakho-ke isilinganiso sokuxuba kumele silinganiswe ngokucophelela.

4. Ukulungiswa Kokukhiqiza Kwezingxube Ezisetshenziswe Kabusha

Ukusebenzisa i-PP ephinde yasetshenziswa kuthinta imingcele yokukhiqiza ebalulekile:

• Amazinga okushisa aphansi okukhipha kanye nokushisa ziyadingeka

• Izilinganiso zokwelula kwentambo eyisicaba kuncishisiwe uma kuqhathaniswa nezinto ezingabonakali kuphela

• Ukuhlanganiswa okufanayo kwezinto ezihlanzekile nezisetshenziswe kabusha kubalulekile

Ukulawula ngokucophelela lezi zilungiso kuqinisekisa kokubili ukuzinza kokukhiqiza kanye nokusebenza komkhiqizo wokugcina.

5. Isiphetho

Ukuvuselela kabusha Ukwelukwa kwe-Pp izikhwama azigcini nje ngokuba nokwenzeka kodwa futhiinzuzo kwezomnotho nakwezemvelo uma isetshenziswa ngokukhetha okufanele izinto kanye nokulawula inqubo. Le ndlela isekela ukukhiqiza okusimeme futhi inikeza indlela esebenzayo eya ekukhiqizeni okuluhlaza embonini yezikhwama ezilukiwe ze-PP.
