Ukuze ucacise isikulufu esisodwa esingena esikhundleni, thumela amaqoqo amane olwazi: imininingwane yomshini nesixhumi esibonakalayo, irekhodi le-dimensional elilawulwayo, into ecutshunguliwe kanye nomsebenzi wokusebenza, kanye nezidingo zokwamukelwa ezicacile. Isampula eligugile liyasiza, kodwa liwubufakazi bakho kokubili umklamo wangempela kanye nomonakalo olandelayo. Imboni kufanele ihlukanise phakathi kwakho kokubili ngaphambi kokugunyaza umdwebo.

Inqubo yokukhiqiza isikulufu kanye nemiphongolo ngokuvamile ihlanganisa ukubuyekezwa kohlelo lokusebenza, ukukhethwa kwempahla kanye nesistimu engaphezulu, ukulungiswa okungenalutho, ukugawula nokuqeda imishini, ukulungiswa kokushisa noma ukufaka ukuqina, ukuqedela ukunemba, ukuhlolwa kwe-dimensional kanye nokupakishwa okuvikelekile. I-oda ayiyona yonke indawo. Kumele kuhlelwe ngokuzungezile ijometri, ukwelashwa kanye nobukhulu bokugcina bengxenye ethile.

I-parallel twin screw extruder inezikulufu ezimbili zokuhlanganisa ezinobubanzi obungashintshi ezakhiwe ngama-elementi emojula. Iningi liyazungeza, ligijima ngesivinini esikhulu ekuxubeni okujulile - okuwenza abe umshini ojwayelekile wokuhlanganisa, i-masterbatch, i-WPC kanye ne-pelletizing. Ngokungafani nomshini we-conical, iphrofayili yesikulufa ingakhiwa kabusha ekwakhiweni okusha ngakunye.

I-screw barrel eyodwa iyisikulufu esisodwa esizungeza ngaphakathi kombhobho oyisilinda esishisayo, sidlulisa, sincibilike futhi simpompa ipulasitiki ngedayizi. Ukusebenza kusethwa ikakhulukazi izinto ezintathu: isilinganiso se-L/D, isilinganiso sokucindezela kanye nohlobo lwesikulufu (okujwayelekile, umgoqo noma ukuxuba). Kuwukukhetha ukonga kakhulu kokukhipha okuphezulu kwempahla efanayo - ukuvunguza kwefilimu, ipayipi elisuka kuma-pellets, ishidi kanye ne-granulation.

I-twin screw extruder isebenzisa izikulufu ezimbili ezihlanganayo ngaphakathi kombhobho onamawele amabili ukondla, ukuncibilikisa, ukuxuba nokumpompa ipulasitiki ngedayizi. Imindeni emibili eyinhloko i-conical (izikulufu ezi-tapered, ezingcono kakhulu zepayipi le-PVC eliqondile, iphrofayili kanye ne-extrusion yebhodi) kanye ne-parallel (ububanzi obungaguquki, izikulufu ezihlukene, ezingcono kakhulu zokuhlanganisa, i-granulation kanye nokuxuba kokugcwalisa okuphezulu).

I-parallel twin screw barrel inezikulufu ezimbili ezihlanganayo ezinobubanzi obungaguquki zigijima eduze emgqonyeni wamawele amabili afanayo. Ngokungafani nomgqomo we-conical, izikulufa zihlala zilingana nosayizi ofanayo ekupheleni, futhi umgqomo uvame ukwakhiwa kusuka ezingxenyeni. Izikulufu ezizungezayo ezihambisanayo zihambisana nokuhlanganisa, i-granulation kanye ne-masterbatch; izikulufo ezihambisanayo ezijikelezayo zihambisana ne-PVC nomsebenzi wokugcwalisa okuphezulu.
