Amasu Okukhipha Ipulasitiki Nezinhlobo Zepulasitiki Ezingacutshungulwa
Ukukhipha ipulasitiki kuyindlela yokukhiqiza evame ukusetshenziswa embonini yepulasitiki. Le nqubo ihilela ukushisa nokuncibilikisa izinto zepulasitiki, ezibe sezidluliswa ngesikhunta noma nge-diye ukuze zakhe umkhiqizo wokugcina onephrofayili ethile. Lesi sihloko sizoxoxa ngokujulile ngokukhipha ipulasitiki kanye nezinhlobo ezahlukene zepulasitiki ezingacutshungulwa kusetshenziswa le ndlela.
Izimiso Eziyisisekelo Zokukhipha Ipulasitiki
Inqubo yokukhipha ipulasitiki iqala ngokufaka izinto zokusetshenziswa zepulasitiki, ngesimo sama-pellet noma ama-granule, ku-extruder hopper. Kusukela ku-hopper, izinto zepulasitiki zithwalwa ziyiswe emgqonyeni noma kwisilinda ngesikulufu esijikelezayo.
Inqubo engaphakathi komgqomo ihilela izindawo ezintathu eziyinhloko:
1. Indawo Yokudla: Yilapho ama-pellets eqala ukwamukelwa futhi athuthwe ngesikulufu.
2. Indawo Yokucindezela: Izinto ziqala ukushiswa nokucindezelwa, okubangela ukuthi ama-pellets ancibilike futhi ashintshe abe yisimo se-semi-liquid.
3. Indawo Yokulinganisa: Izinto ezincibilikisiwe ziyacindezelwa futhi zilinganiswe ngaphambi kokuba zinikwe idayisi.
Ngemva kokulinganiswa nokucindezelwa, izinto ezincibilikisiwe zifakwa kudayi, okunikeza umkhiqizo ophumayo isimo sokugcina. Umkhiqizo ube usupholiswa kancane kancane ukuze uqine futhi ugcine isimo sawo, ngaphambi kokuba usikwe noma uqhubeke nokucutshungulwa njengoba kudingeka.
Izinhlobo Zezindlela Zokukhipha Ipulasitiki
Kunezinhlobo eziningana zamasu okukhipha ipulasitiki avame ukusetshenziswa embonini, okuhlanganisa:
1. I-Simple Die Extrusion: Le ndlela ilula kakhulu futhi isetshenziselwa ukukhiqiza imikhiqizo enesimo sephrofayili esifanayo, njengezinduku zepulasitiki, amabhodi, noma amapayipi.
2. Ukubumba Okuphumayo: Le nqubo isetshenziselwa ukwenza imikhiqizo engenalutho njengamabhodlela nezitsha zepulasitiki. Kule ndlela, i-parison (ithubhu eliwuketshezi) ishaywa umoya ize inamathele odongeni lwesikhunta.
3. Ukukhipha Ifilimu: Indlela esetshenziswa ukwenza amafilimu epulasitiki amancane kakhulu, njengokupakisha ipulasitiki, kusetshenziswa indlela yefilimu efakwe noma efakwe umoya.
4. Ukwemboza Okungeziwe: Le nqubo ihilela ukumboza ezinye izinto ezifana nephepha noma indwangu ngepulasitiki, esetshenziswa ekwenziweni kokupakisha okuguquguqukayo.
5. Ukukhishwa Okuqoshiwe (Ukukhishwa Kwephrofayili): Kusetshenziselwa ukwenza imikhiqizo enamaphrofayili ayinkimbinkimbi, njengezinhlaka zamafasitela noma amaphrofayili eminyango.
6. I-Twin Screw Extrusion: Isebenzisa izikulufo ezimbili ezijikeleza ngokuvumelana ukuze kuhlanganiswe kangcono futhi kucutshungulwe ngokushesha, ezifanele ukukhiqizwa okuhlanganisiwe nokuxuba.
Izinhlobo Zepulasitiki Ezingacutshungulwa Ngokusebenzisa Amasu Okukhipha Izinto
Ukukhishwa kwepulasitiki kuhambisana nezinhlobonhlobo zama-polymer, ngalinye linezici ezihlukile kanye nezinhlelo zokusebenza. Amanye amapulasitiki avamile acutshungulwa kusetshenziswa le ndlela afaka:
1. I-Polyethylene (PE): Yakhiwa izinhlobo eziningana, okuhlanganisa:
– I-Polyethylene Ephansi (LDPE): Isetshenziselwa ukwenza amafilimu epulasitiki, izikhwama zokuthenga, namabhodlela aguquguqukayo.
– I-High-Density Polyethylene (HDPE): Isetshenziselwa amapayipi, amabhodlela, kanye nokuvala.
– I-Linear Low-Density Polyethylene (LLDPE): Ngokuvamile isetshenziselwa izinto eziguquguqukayo ezifana namafilimu okugoqa.
2. I-Polypropylene (PP): Ipulasitiki eguquguqukayo evame ukusetshenziselwa izitsha zokudla, izindwangu, kanye namadivayisi ezokwelapha. I-PP inokumelana okuhle nokushisa kanye namakhemikhali.
3. I-Polyvinyl Chloride (PVC): Isetshenziswa ngezindlela eziqinile neziguquguqukayo ezisetshenziswayo njengezipayipi, phansi kwe-vinyl, kanye nokuvikela izintambo. I-PVC ayishisi futhi ayishisi.
4. I-Polystyrene (PS): Isetshenziselwa ukwakha imikhiqizo efana nezinkomishi ezilahlwayo, ukupakishwa kokudla, kanye nezingxenye ze-elekthronikhi. I-PS icacile futhi ingenziwa ngobuningi obuhlukahlukene.
5. I-Acrylonitrile Butadiene Styrene (ABS): Ipulasitiki eqinile emelana nokushisa okuphezulu, evame ukutholakala emikhiqizweni yezimoto, ezimbozweni zikagesi, nasemathoyizini.
6. I-Polyamide (i-Nylon): Ipulasitiki enamandla aphezulu futhi emelana nokungqubuzana, evame ukusetshenziswa ekwenziweni kwezingxenye zomshini, izingxenye zezimoto ezisele, kanye nezindwangu.
7. I-Polyethylene Terephthalate (PET): Isetshenziswa kakhulu embonini yokupakisha ukudla neziphuzo kanye nemikhiqizo yendwangu efana ne-polyester fiber.
8. I-Polychlorotrifluoroethylene (PCTFE): Ipulasitiki enokumelana okuhle kwamakhemikhali nokushisa, evame ukusetshenziswa ezisetshenziswa kwezokwelapha nasemkhathini.
Izinzuzo kanye Nezinselele Zokukhishwa Kwepulasitiki
Amasu okukhipha ipulasitiki anezinzuzo eziningana ezenza kube ukukhetha okuthandwayo embonini:
– Ukukwazi Ukukhula: Le nqubo ifanelekela ukukhiqizwa okukhulu, okwenza isebenze kahle ezimbonini ezinezidingo eziphezulu zokukhiqiza.
– Izindleko Ezisebenzayo: Nakuba kudinga ukutshalwa kwezimali kokuqala emishinini, inqubo yokukhipha ivumela ukonga isikhathi eside ngenxa yezinto eziphinde zisetshenziswe kanye nokusebenza kahle.
– Ukuzivumelanisa nezimo: Ivumela izinhlobo ezahlukene zemiklamo yomkhiqizo kanye nezinhlelo zokusebenza ezivela ohlotsheni olulodwa lwenqubo.
– Isivinini Sokukhiqiza: Izinqubo eziqhubekayo, ezingayeki zivumela ukukhiqizwa okusheshayo nokungaguquguquki.
Kodwa-ke, kunezinselele ezikhona kumasu okukhipha ipulasitiki:
– Ukulawulwa Kwekhwalithi: Ukuqinisekisa ikhwalithi yomkhiqizo wokugcina kudinga ukulawulwa okuqinile, ikakhulukazi maqondana nobukhulu nobukhulu.
– Ukuhambisana kwezinto: Akuzona zonke izinto zepulasitiki ezihambisana nazo zonke izinhlobo zamadayi kanye nezinhlelo zokusebenza, okudinga ukukhethwa okufanele.
– Ukulungisa: Imishini yokukhipha idinga ukunakekelwa nokugcinwa njalo ukuze kugwenywe isikhathi sokungasebenzi.
– Ukukhathazeka Ngezemvelo: Ukusetshenziswa kwepulasitiki kunomthelela omkhulu kwezemvelo, ngakho-ke ukuphathwa kwemfucuza okuphumelelayo kuyadingeka.
Isiphetho
Ukukhishwa kwepulasitiki kuyindlela ephumelelayo neguquguqukayo edlala indima ebalulekile ekukhiqizweni kwepulasitiki. Ngokuqonda izimiso eziyisisekelo zokukhishwa kwepulasitiki, amasu ahlukahlukene atholakalayo, kanye nezinto zepulasitiki ezingacutshungulwa, izimboni zingasebenzisa lobu buchwepheshe ezinhlotsheni ezahlukene zezicelo. Kodwa-ke, ukunaka ukulawulwa kwekhwalithi, ukuhambisana kwezinto, kanye nokukhathazeka ngemvelo kubalulekile ekukhiqizweni okuhle nokuqhubekayo.
