2.5 Extrusion Granulation

I-Extrusion granulation linyathelo eliphambili kwinkqubo yokwenziwa ngokutsha kwenkunkuma yeplastiki. Kubandakanya ukunyibilika, ukuxuba, kunye ne-homogenizing amaqhekeza eplastiki atyunyuziweyo omisiwe usebenzisa i-extruder, emva koko ukhupha iplastiki etyhidiweyo ngedayisi ukwenza imicu eqhubekayo, ezithi emva koko zipholiswe kwaye zisikwe kwiigranule ezifanayo.

I-extruder sisixhobo esiphambili kweli nyathelo, kunye nokusebenza kwayo kumisela ngokuthe ngqo umgangatho kunye nokusebenza kakuhle kwenkqubo yegranulation. Kukho iindidi ezimbini eziphambili ze-extruders ezisetyenziswa kwinkunkuma yeplastiki yokuphinda isetyenziswe igranulation: i-twin-screw extruders kunye ne-single-screw extruders. Uhlobo ngalunye lunenzuzo yalo kwaye lufanelekile kwiindidi ezahlukeneyo zeeplastiki zenkunkuma, njengoko kucacisiwe kwiCandelo 3.

Ngexesha le-extrusion granulation, iiparamitha zenkqubo engundoqo ezininzi kufuneka zilawulwe ngokuchanekileyo:

Ubushushu: Ubushushu bomgqomo we-extruder kunye nokufa kubalulekile ekunyibilikiseni iplastiki kunye nokuqinisekisa ukuxuba okulungileyo kunye ne-homogenization.. Iindidi ezahlukeneyo zeplastiki zineendawo ezahlukeneyo zokunyibilika, kwaye iqondo lobushushu lomphanda ngokuqhelekileyo libekwe kwi-10-30 ° C ngaphezu kwendawo yokunyibilika yeplastiki ukuqinisekisa ukunyibilika okupheleleyo.. Umzekelo, iqondo lobushushu lomphanda wePP lidla ngokuba yi-170-220°C, ngelixa kwi-PET yi-260-280 ° C. Ukushisa okuphezulu kakhulu kunokubangela ukuthotywa kwe-thermal yeplastiki, okukhokelela ekuncitshisweni kweempawu zemishini yeegranules ezihlaziyiweyo, ngelixa amaqondo obushushu aphantsi kakhulu anokubangela ukunyibilika okungagqibekanga kunye nokuxutywa kakubi.
Ireyithi yokucheba: Isantya sokucheba simiselwa sisantya se-screw kunye noyilo lwe-screw. Izinga elifanelekileyo lokucheba linceda ukwenza i-homogenize iplastiki etyhidiweyo, sasasaza naziphi na izingcolisi eziseleyo, and improve the plasticity of the granules. Nangona kunjalo, excessively high shear rates can cause mechanical degradation of the plastic molecular structure, leading to reduced performance.
Isantya seScrew: The screw speed affects the throughput, melting efficiency, and mixing quality. Higher screw speeds can increase the throughput but may reduce the melting and mixing efficiency, while lower screw speeds can improve the mixing quality but reduce the throughput. The optimal screw speed depends on the type of plastic, the extruder type, and the desired granule quality.
Uxinzelelo lwe-Extrusion: The extrusion pressure is determined by the die design, isantya sokujija, and material viscosity. Stable extrusion pressure ensures uniform strand formation and consistent granule size. Excessively high pressure can cause die blockage, while excessively low pressure can result in uneven strands.

2.6 Ukupholisa kunye nokusika

Emva kwe-extrusion ngokufa, imicu yeplastiki eqhubekayo ipholiswa ukuze iqine. Ukupholisa kungenziwa ngokusebenzisa ukupholisa umoya okanye ukupholisa amanzi. Ukupholisa amanzi kusebenza ngakumbi kwaye kusetyenziswa ngokubanzi kwimisebenzi yegranulation enkulu, kubandakanya ukugqithiswa kwemicu ngetanki yamanzi okanye isitshizi samanzi ukupholisa ngokukhawuleza kwiqondo lobushushu begumbi. Ukupholisa komoya kulungele imisebenzi emincinci okanye iiplastiki ezinochuku kumanzi (njengeeplastiki ezithile zobunjineli).

Emva kokuba imicu ipholile kwaye iqiniswe, zisikwa kwiigranule ezifanayo kusetyenziswa i-pelletizer. I-pelletizer ifakelwa ngokuqhelekileyo ekuphumeni kwenkqubo yokupholisa kwaye inokulungiswa ukulawula ubude beegranules. (ngokuqhelekileyo phakathi kwe-2mm kunye ne-5mm). Iintlobo eziqhelekileyo zeepelletizers ziquka i-strand pelletizers, iipelletizers zamanzi, kunye neepelletizers zangaphantsi kwamanzi. I-Strand pelletizers lolona hlobo lusetyenziswa kakhulu kwinkunkuma yeplastiki yokuphinda isetyenziswe igranulation, njengoko zilula kwisakhiwo, kulula ukusebenza, kwaye ifanelekile kwiindidi ezininzi zeplastiki.

2.7 Ukuhlola kunye nokuPakisha

Emva kokusika, iigranuli ezisetyenzisiweyo ziyajongwa kusetyenziswa isikrini esingcangcazelayo ukususa naziphi na iigranule ezinobukhulu obugqithisileyo okanye obungaphantsi., ukuqinisekisa ubungakanani bamasuntswana afanayo. Iigranule ezikhuselweyo zomiswa kwakhona (ukuba kuyafuneka) ukususa nabuphi na ubumanzi obufunliweyo ngexesha lokupholisa, emva koko zipakishwe kwiibhegi okanye kwizikhongozeli ezininzi ukuze zigcinwe kwaye zithuthwe.

Ukupakishwa linyathelo elibalulekileyo lokuthintela ukungcoliseka kunye nokufunxwa kokufuma kweegranules ezihlaziyiweyo.. Izinto zokupakisha kufuneka zibe bubungqina bokufuma kwaye zicoceke, kwaye iigranules kufuneka zigcinwe kwindawo eyomileyo, ngenisa umoya, kunye nesitora esicocekileyo ukugcina umgangatho wabo.

3. UkuKhetha i-Extruder yeNkunkuma yePlastiki yokuRecycling iGranulation

I-twin-screw extruders ezijikelezayo zisetyenziswa kakhulu ekusetyenzisweni ngokutsha kweplastiki ngenxa yobuchule bazo obuphezulu bokuxutywa kunye nokuhambisa..

3.1.1 Key Advantages of Twin-screw Extruders

Easy Material Feeding: Twin-screw extruders have a strong conveying capacity, which allows for easy feeding of crushed plastic pieces, even if they are irregular in shape or have a certain amount of contaminants. This reduces the need for pre-processing of the material and improves production efficiency.
Short Material Residence Time: The residence time of the material in the twin-screw extruder is short (ngokwesiqhelo 1-5 imizuzu) compared to single-screw extruders. This helps to avoid thermal degradation of the plastic, especially for heat-sensitive plastics such as PET and ABS, which can degrade easily when exposed to high temperatures for a long time. Short residence time also reduces energy consumption and improves production efficiency.
Excellent Venting Effect: Twin-screw extruders are equipped with venting ports that allow for the removal of moisture, volatile gases, and air from the molten plastic. The meshing part of the screws provides effective mixing, and the self-cleaning function of the venting section ensures that the material can achieve complete surface renewal, allowing for efficient removal of volatile substances. This helps to improve the quality of the recycled granules by reducing the number of bubbles and defects.
