Izinhlobo Ezivamile Zepulasitiki Nezicelo Zezimboni
Ipulasitiki ingenye yezinto ezisebenziseka kakhulu embonini yanamuhla. Ukuba khona kwayo cishe kuzo zonke izingxenye zokuphila, kusukela emakhaya nasemahhovisi kuya ezimbonini ezinkulu, kubonisa ukubaluleka kwayo. Ipulasitiki ayiguquguquki nje kuphela kodwa futhi inamandla, ukuqina, nezinye izakhiwo ezenza ibe usizo kakhulu ezinhlobonhlobo zezicelo. Kulesi sihloko, sizoxoxa ngezinhlobo zepulasitiki ezivame ukusetshenziswa embonini kanye nezicelo zazo ezivamile.
1. I-Polyethylene (PE)
Izinhlobo ze-Polyethylene
– I-Polyethylene Enobuningi Obuphezulu (i-HDPE)
– I-Polyethylene Ephansi (LDPE)
– I-Linear Low-Density Polyethylene (LLDPE)
Izinhlelo zokusebenza ze-HDPE
I-HDPE isetshenziswa ekwenziweni kwamabhodlela obisi epulasitiki, izitsha, namapayipi amanzi. I-HDPE imelana nezincibilikisi eziningi, okwenza ifaneleke kahle ekusetshenzisweni okudinga ukumelana namakhemikhali.
Izinhlelo zokusebenza ze-LDPE
I-LDPE isetshenziswa ekwenziweni kwepulasitiki yokusonga, izikhwama zepulasitiki, namabhodlela athambile. I-LDPE iguquguquka kakhulu futhi inokumelana okuhle nomswakama namakhemikhali.
Izinhlelo Zokusebenza ze-LLDPE
I-LLDPE ivame ukusetshenziswa embonini yamafilimu epulasitiki, lapho kudingeka khona amandla aphezulu okudonseka nokudabuka. Izibonelo zifaka phakathi ama-stretch wrap nama-packaging liners.
2. I-Polypropylene (PP)
Izicelo ze-Polypropylene
I-PP yaziwa ngamandla ayo, ukunwebeka kwayo, kanye nokumelana namakhemikhali. I-PP ivame ukusetshenziswa ekukhiqizeni amaphakheji okudla, izitsha zokugcina izinto, izingxenye zezimoto ezifana nama-bumper, kanye namafilimu epulasitiki e-ceramic amabhethri.
3. I-PVC (i-Polyvinyl Chloride)
Izinhlobo ze-PVC
- I-PVC eqinile
- I-PVC eguquguqukayo
Izicelo ze-PVC eziqinile
I-PVC eqinile isetshenziswa ekwakhiweni kwamapayipi, ozimele bamafasitela, kanye namaphrofayili okwakha. Amandla ayo kanye nokumelana nomlilo kwenza kube ukukhetha okuphezulu ekwakheni.
Izicelo ze-PVC eziguquguqukayo
I-PVC eguquguqukayo isetshenziswa ezintanjeni zikagesi, ezimbozweni zaphansi, kanye nasezindlini zokuhlobisa. Ukuguquguquka kwayo kanye nokuguquguquka kwayo kuyenza ibe nokuguquguquka okukhulu ezindleleni eziningi ezahlukene.
4. I-Polystyrene (PS)
Izicelo ze-Polystyrene
I-Polystyrene ingatholakala ku-foam (njenge-Styrofoam) kanye nezinhlobo zepulasitiki eqinile. Ukusetshenziswa okuvamile kufaka phakathi izitsha zokudla okusheshayo, ukuvikela ukushisa, kanye nokupakishwa okuvikelayo. Izinzuzo zayo zifaka phakathi izindleko zayo eziphansi kanye nokulula kokukhiqizwa.
5. I-Polyethylene Terephthalate (i-PET noma i-PETE)
Izicelo ze-PET
I-PET isetshenziswa kabanzi emabhodleleni eziphuzo kanye nasekupakishweni kokudla. Ukucaca kwayo okubonakalayo, amandla, kanye nokuqina kwamakhemikhali kwenza kube ukukhetha okuhle kakhulu kokusetshenziswa lapho kudingeka khona ukucaca kanye nesithiyo kumagesi kanye nomswakama.
6. I-Acrylonitrile Butadiene Styrene (ABS)
Isicelo se-ABS
I-ABS ivame ukusetshenziselwa imikhiqizo ye-elekthronikhi yabathengi njengamakesi ekhompyutha, izinto zasendlini, kanye nezingxenye zezimoto. Ukumelana kwayo nokungaguquki kanye nokubumba kwayo kuyenza ithandwe ezimbonini ezahlukahlukene.
7. Inayiloni (i-Polyamide)
Izicelo ze-Nylon
Inayiloni isetshenziswa ezindwangu ukwenza izindwangu, kanye nasezingxenyeni zomshini ezifana namagiya nama-bearings. Amandla ayo okusebenza kanye nokumelana nokuguguleka okuhle kwenza kube ukukhetha okuvamile ezinhlotsheni zobunjiniyela.
8. I-Polycarbonate (PC)
Izicelo ze-Polycarbonate
I-PC yaziwa ngokumelana kwayo okuhle kakhulu nokubonakala kwayo okukhanya. Isetshenziswa ekwenziweni kwengilazi yokuphepha, amalensi okukhanya, namadivayisi ezokwelapha. Lezi zakhiwo ziyenza isetshenziswe kaningi ezisetshenzisweni zesakhiwo esinamandla aphezulu.
9. I-Polyurethane (PU)
Izicelo ze-Polyurethane
I-PU isetshenziswa ngezindlela ezahlukene, okuhlanganisa igwebu eliguquguqukayo neliqinile. Ukusetshenziswa kwayo kufaka phakathi omatilasi, amakhushini, kanye nokushisa. Amandla ayo okubumba ukuze ibe nobunzima obuningi kanye nokuguquguquka kwenza i-PU ibe usizo kakhulu ezinhlotsheni ezahlukene zezimboni.
10. I-Polytetrafluoroethylene (PTFE)
Izicelo ze-PTFE
I-PTFE, eyaziwa kangcono ngegama lomkhiqizo i-Teflon, isetshenziswa ezicelweni ezidinga ukumelana namakhemikhali nokushisa okuphezulu, njengezimbozo, izivalo, kanye nokushisa kukagesi. Izakhiwo zayo ezinganamatheli ziyenza ifaneleke kakhulu ezitsheni zokupheka njengezimbiza namapani.
Isiphetho
Uhlobo ngalunye lwepulasitiki lunezakhiwo ezihlukile ezenza lufanelekele ukusetshenziswa okuthile. Kusukela ekuguquguqukeni kwe-LDPE kuya emandleni e-nylon, kusukela ekukhanyeni kwe-PET kuya ekumelaneni namakhemikhali kwe-PTFE—amapulasitiki adlala indima ebalulekile ekuthuthukisweni kwemboni yanamuhla. Ukuqonda izinhlobo zepulasitiki kanye nezicelo zazo ezivamile kuvumela izimboni ukuthi zikhethe izinto ezifanele ukuhlangabezana nezidingo zazo ezithile. Lokhu akugcini nje ngokuthuthukisa ukusebenza kahle kokukhiqiza kanye nekhwalithi kodwa futhi kusekela ukusungula izinto ezintsha kanye nokusimama. Ngakho-ke, ulwazi lwezinhlobo zepulasitiki kanye nezicelo zazo lubalulekile kubo bonke ochwepheshe bezimboni.
