I-Plastiki extrusion, eyaziwa ngokuba yi-plasticating extrusion, yinkqubo eqhubekayo yokuvelisa umthamo ophezulu apho i-thermoplastic material - ngendlela yomgubo, iipellets okanye i-granulates - inyibilika i-homogeneously kwaye ikhutshwe ngaphandle kokubunjwa ifa ngendlela yoxinzelelo. Kwi-screw extrusion, uxinzelelo luvela kwi-screw rotation ngokuchasene nodonga lombhobho. Njengoko inyibilika yeplastiki idlula kwidiyizi, ifumana imilo yomngxuma wokufa kwaye iyishiye i-extruder. Imveliso ekhutshiweyo ibizwa ngokuba yi-extrudate.
I-extruder eqhelekileyo inezowuni ezine:
Indawo yokutya
Kulo mmandla, ubunzulu benqwelomoya buhlala buhleli. Umgama phakathi kwedayamitha enkulu phezulu kwinqwelomoya kunye nedayamitha encinci yesikrufu emazantsi endiza bubunzulu bokubhabha.
Indawo yoTshintsho okanye uMmandla wokuNxinzelela
Ubunzulu benqwelomoya buqala ukuhla kulo mmandla. Enyanisweni, izinto ze-thermoplastic zixinzelelwe kwaye ziqala ukwenza iplastiki.
Indawo yokuxuba
Kulo mmandla, ubunzulu benqwelomoya buphinda buhlale buhleli. Ukuqinisekisa ukuba izinto eziphathekayo zinyibilike ngokupheleleyo kwaye zixutywe ngokulinganayo, into ekhethekileyo yokuxuba inokuba ikhona.
Indawo yokulinganisa
Lo mmandla unobunzulu bokubhabha obuncinci kunendawo yokuxuba kodwa uhlala ungatshintshi. Kwakhona, uxinzelelo lutyhala inyibilika ngokufa kwe-shaping kule zowuni.
Kwelinye inqaku, ukunyibilika komxube wepolymer kubangelwa zizinto ezintathu eziphambili:
Ukugqithiselwa kobushushu
Ukutshintshwa kobushushu ngamandla adluliswa ukusuka kwi-extruder motor ukuya kwi-extruder shaft. Kwakhona, ukunyibilika kwepolymer kuchatshazelwa yiprofayili ye-screw kunye nexesha lokuhlala.
Ukukhuhlana
Oku kuziswe kukukhuhlana kwangaphakathi komgubo, iprofayile ye-screw, isantya se-screw, kunye nesantya sokutya.
I-Extruder Barel
Izilawuli ezintathu okanye ngaphezulu ezizimeleyo zokushisa zisetyenziselwa ukugcina ubushushu bemibhobho.
