Ensimini enamandla neguqukayo yokukhishwa kwamapayipi epulasitiki, ukuqonda umehluko phakathiisikulufu esisodwaabathuthi futhiizikhumuli eziphindwe kabili kubaluleke kakhulu. Lezi zinhlobo ezimbili ze-extruder zidlala indima ebalulekile enkambisweni yokukhiqiza, ngayinye inezici zayo kanye nezinzuzo zayo.
Ii-extruder eyodwa yesikulufa Sekuyisikhathi eside iyinto ebalulekile embonini. Yenzelwe ikakhulukazi ukwenza ama-polymer abe yipulasitiki futhi akhishwe. Uma kukhulunywa ngemikhiqizo ye-granular, iyakhanya ngempela. Isibonelo, ekukhiqizweni kwamapayipi epulasitiki avamile, ama-extruder esikulufo esisodwa avame ukuba yiwona akhethwa kakhulu. Asebenza ngokuthatha izinto ze-polymer ze-granular bese encibilikisa kancane kancane bese ezixuba ngokujikeleza kwesikulufo esisodwa ngaphakathi komgqomo oshisayo. Le nqubo iqinisekisa ukugeleza okuhambisanayo kwezinto ezincibilikisiwe, ezibe sezicindezelwa ngedayisi ukuze zakhe isimo sepayipi esifiselekayo.
Ngakolunye uhlangothi, i-i-extruder ephindwe kabiliinikeza isethi ehlukile yamakhono. Inekhono kakhulu ekuphatheni ukucubungula i-powder. Ikakhulukazi, uma isebenza ngezinto ze-PVC ezixutshwe ngopuleti, ibonisa ukusebenza okumangalisayo. Ukucushwa kwezikulufo ezimbili kuvumela ukuxubana okunamandla kanye nokwenza i-plastici ibe yi-plastic. Izikulufo ezimbili zijikeleza ngendlela ehlelekile, zidala umphumela wokugunda ohlanganisa kahle izingxenye ze-powder. Lokhu kuzuzisa kakhulu ezimweni lapho kudingeka ukuxuba okunembile kwezithasiselo kanye nama-fillers ne-polymer eyisisekelo.
IShayina ivele njengeqembu elikhulu emakethe yomhlaba wonke ye-extruder yepulasitiki. Njengoba inabakhiqizi abaningi be-extruder yepulasitiki kanye nezimboni zemishini ye-extruder, izwe lihamba phambili ekusunguleni nasekukhiqizeni. Phakathi kwabo, iBlesson ivelele njengomkhiqizi ohamba phambili we-extruder yaseShayina. Imigqa yabo yokukhiqiza amapayipi, ehlanganisa ubuchwepheshe be-single screw kanye ne-double screw extruder, ithole idumela lekhwalithi ephezulu kanye nokuthembeka.
I-extruder eyodwa yesikulufo ekusethweni kwe-extruder yepulasitiki yaseShayina ejwayelekile inikeza ubulula kanye nokusebenza kahle kwezindleko. Kulula ukuyisebenzisa nokuyinakekela, okwenza kube ukukhetha okuthandwayo kwamabhizinisi amaningi amancane kuya kwaphakathi okukhiqiza amapayipi. Kodwa-ke, ukulinganiselwa kwayo kuyacaca lapho kukhulunywa ngezakhiwo eziyinkimbinkimbi noma izinto ezidinga ukuhlanganiswa okubanzi.
Ngokuphambene nalokho, i-extruder ephindwe kabili, njengoba kubonakala emigqeni yokukhiqiza amapayipi athuthukile eShayina, inikeza ukuxubana okuthuthukisiwe kanye nokuhlanganiswa okuhlanganisiwe. Lokhu kubalulekile ekukhiqizeni amapayipi anezakhiwo ezisezingeni eliphezulu zemishini kanye nekhwalithi ehambisanayo. Ikhono lokuphatha izinto zempuphu ngokuqondile linikeza abakhiqizi ukuguquguquka okwengeziwe ekutholeni izinto zokusetshenziswa kanye nokwenza izingxube ezenziwe ngokwezifiso.
Isibonelo, ku-ukukhiqizwa kwamapayipi e-PVC asebenza kahle kakhuluNgezithasiselo ezithile zokuqina nokumelana okuthuthukisiwe, i-extruder ephindwe kabili ingaqinisekisa ukusatshalaliswa okufanayo kwalezi zithasiselo kuyo yonke i-polymer matrix. Lokhu kuphumela kumapayipi angamelana nengcindezi enkulu, ukushintshashintsha kwezinga lokushisa, kanye nokucindezeleka kwemvelo.
Ekuphetheni, kokubili izikulufo ezi-single kanye nezikulufo ezimbili zinezindawo zazo ezifanele embonini yokukhipha amapayipi epulasitiki. Ukukhetha phakathi kwazo kuncike ezintweni ezahlukahlukene njengohlobo lwezinto okufanele zicutshungulwe, ikhwalithi yomkhiqizo oyifunayo, kanye nomthamo wokukhiqiza. E-China, abakhiqizi abanjengoBlesson bayaqhubeka nokucwengisisa nokwenza ngcono lobu buchwepheshe bokukhipha, beqhuba intuthuko yomugqa wonke wokukhiqiza amapayipi epulasitiki. Njengoba imboni iqhubeka, ucwaningo olwengeziwe kanye nentuthuko kulindeleke ukuthi luvule amandla engeziwe avela kule mishini ebalulekile yokukhipha, okuvumela ukukhiqizwa kwamapayipi epulasitiki amasha futhi asezingeni eliphezulu ukuze kuhlangatshezwane nezidingo ezikhula njalo zemikhakha ehlukahlukene njengokwakha, amapayipi, kanye nezicelo zezimboni.
