Ngophuhliso lwesayensi kunye netekhnoloji kunye nokuphuculwa kwemigangatho yokuphila kwabantu. Kwelinye icala, ukusetyenziswa kweplastiki kuzise lula ebomini. Kwelinye icala, ngenxa yokusetyenziswa kakhulu kweplastiki, iplastiki yenkunkuma izisa ungcoliseko lwendalo. Kwangelo xesha, ukuveliswa kweplastiki kutya izibonelelo ezininzi ezingenakuvuseleleka ezinje ngeoyile, ekhokelela ekunqongopheni kwezixhobo. Ke ngoko, izibonelelo ezingafikelelekiyo kunye nokungcoliseka kwendalo kunye nokungcoliswa kwendalo ziye zazixhalabisa onke onke amacandelo oluntu, kwaye igrafu yeplastiki yokuphinda isebenze kwakhona iphinde iqwalaselwe.

Zeziphi izinto zeplastiki?
Iiplasitiki zisetyenziswa ngokubanzi kwezinto zePolymer, eziqulunqwe nge-polymers (i-resins) kunye nokongezwa. Iplastiki eyenziwe ngeplastikhi yeentlobo ezahlukeneyo ze-polymers ezinobunzima obuhlukeneyo, kwaye iipropathi zeplastiki zepolymer efanayo nazo zahlukile ngenxa yeezongezo ezahlukeneyo.
Uhlobo olufanayo lweemveliso zeplastiki zinokwenziwa kwiplasitiki eyahlukileyo, njengefilimu yePolythylene, i-polyproplene ifilimu, i-polyvinyl chlorinyl chlorinyl ifilimu, njalo njalo. Uhlobo lweplastiki lunokwenziwa kwiimveliso ezahlukeneyo zeplastiki, njenge-polypropylene ye-polyproplene ingenziwa kwifilimu, i-outur ye-ofisi ye-ofisi, ibhegi ebophayo, ibhotile, i-balin, i-barrel, njalo njalo. Kwaye ukwakhiwa kwe-resin, ubunzima bemolekyuli, kunye nefomula esetyenziswa kwiimveliso ezahlukeneyo zahlukile, ezizisa ubunzima ekuqhubekeni kweplastiki yenkunkuma.
Sisiphi isakhiwo esinemigram?
I-granulator yeplastiki iqulunqwe ngomatshini ophambili kunye nomatshini oncedisayo.Umatshini ophambili ngumxhasi, oqulunqa inkqubo yokuphuma, inkqubo yokutshisa kunye nokufudumeza kunye nokufudumeza. Inkqubo yokuphumelela ibandakanya isikrelem, i-barrel, i-hopper, intloko kwaye isweleke, njl njl. Inxulumene ngqo nenqanaba lesicelo kunye nemveliso yomntu ophumeleleyo. Iyenza intsimbi enganyangekiyo encomekayo. Umsebenzi wenkqubo yokuhambisa kukuqhuba isikhafu kwaye unike i-torque kunye nesantya esifunwa sisikhafu kwinkqubo yokuphendulwa. Ihlala idityaniswe ngemoto, incitshisiwe, kwaye ithwele. Ukufudumeza kunye nokupholisa kokufudumeza kunye nesixhobo sokupholisa yimeko eyimfuneko yenkqubo yokuphumelela kweplastiki.
