Ungayikhetha kanjani indlela yokusika yomshini wokwenza i-granulation oguquliwe ohlukile #granules

NgoDisemba, ekupheleni konyaka, kusenemishini ethunyelwa emazweni ahlukene, efektri yamakhasimende. Unjiniyela wethu umatasa ufaka umshini wokuhlanganisa.

Kusuka e-Iran

Igama lomshini: Umshini wokuxuba umugqa wokuhlanganisa umbala wesikulufa esisodwa
Amandla: 500kg/h
Ukusetshenziswa: PE Color masterbatch

Kusuka eTurkey

Igama lomshini: TPE Twin-screw underwater cutting granulation line

Amandla: 400kg/h

Ukusetshenziswa: Izivimbamgwaqo ze-TPE, izigaxa zomgwaqo

Kusuka eLibya

Igama lomshini: I-PET Twin-screw water cutting granulation line

Amandla: 800kg/h

Ukusetshenziswa: Ishidi le-PET nezinto zokupakisha

Lapho i-resin ehlanzekile ihlangana "nokuguqulwa", indlela yokusika efaneleke kakhulu imvamisa iyashintsha.

Gcwalisa

Ikakhulukazi, ukugcwaliswa okuphezulu kuvame ukuvumela i-LLDPE noma i-LDPE pelleting ukuthi ishintshwe ngendandatho yamanzi iye ekushiseni okupholile emoyeni. Akugcini nje ukwandisa ukuqina, kodwa futhi ulondoloze ugesi (gcina ngemva kokumisa); Umumo wokusanhlamvu muhle futhi wehlisa ukusetshenziswa kwempushana ewunqenqema.#imishini yokuthambisa

Thuthukisa

Ngenxa yokuba khona kwefayibha yengilazi noma i-carbon fiber, vumela amanye ama-resin ashisayo apholile (i-HDPE, i-ABS, njll.) abuyele emgqeni wendabuko (amanzi) wokusika okubandayo. "Universal", "engineering" (ipulasitiki), ayikwazi ukukhishwa.

Ukuqina

Isibonelo, i-TPV bumper exclusive material (PP+EPDM+POE dynamic vulcanization), ngoba isigaba esihlakaziwe sempushana yerabha sigcwalisa isigaba esiqhubekayo se-PP, ukushisa kwendandatho yamanzi kuba yinketho yokuqala. Kokubili okuhle nokonga izindleko.

I-extrusion esebenzayo

(1)Chemical crosslinked wire and cable (XL-PE) into yokuqala ukukhetha ukushisa komoya opholile. Ezimbonini eziningi zezintambo nezintambo, umshini we-twin-screw/screw-single-stage double-stage + ukushisa okupholile komoya (noma ukushisa kwe-eccentric) kuyi-SPVC ne-XLPE ehambisanayo yokukhiqiza kanye nezinga lokucubungula.

(2) Ekukhiqizeni nasekucubunguleni i-polypropylene yamandla aphezulu ancibilika (HMS-PP), indandatho yamanzi okusanhlamvu okushisayo ingenziwa kalula ngemva kokusabela kwe-PP.

Okujwayelekile okwengeziwe okulungisiwe okukhethekile noma i-masterbatch

Sika ikesi lokukhetha uhlobo lokusanhlamvu

1. Impahla yokufaka ikhebula le-SPVC noma impahla yezokwelapha esobala kuphela, into yokuqala okufanele uyikhethe wukushisa okupholile emoyeni. Kanjalo ne-RPVC, kodwa ngamanani amancane. #pvc umshini wokuhlanganisa

2. I-Polystyrene, kungakhathaliseki ukuthi i-HIPS noma i-GPPS, iningi lebhande lokuphonswa (amanzi athambekele apholile) umugqa wokusika.

3. Impahla ye-ABS ekhethekile, iningi lenduku ekhethiwe (amanzi) ukusika okubandayo (isimo sokusanhlamvu esincanyana neside sifunwa kakhulu). Abantu baye bazama ukushisa okupholile emoyeni noma ukushisa kwendandatho yamanzi kungaba, ukuma okusanhlamvu nakho kuhle futhi kuyaphana (i-positive spherical). Uma okukhiphayo kudlula u-3-4t/h, kungokwemvelo ukushintsha ukushisa kwamanzi noma umshini wokulingisa ngemichilo.

4. Impahla yocingo evikelekile noma evikelekile kancane, indandatho encane yokukhetha amanzi, ukukhethwa okukhulu kwamanzi ngaphansi kwamanzi (kuyashisa).

5. Izinto zekhebula ezixhumene neSilane, ulayini omncane ukhetha indandatho yamanzi, enkulu (efana nomugqa wama-96/250) khetha ngaphansi kwamanzi (kushisa).

6. I-HFFR (intambo ephansi yekhebula le-halogen engenayo intuthu ephansi) ukucubungula ukukhiqizwa nokusika, kuhambisana nezisetshenziswa ze-XLPE, kodwa ukucushwa kwesikulufa kuzoshintsha.

7. Ukuphela kokuvalwa kwe-Copolymer formaldehyde (POM), kungakhetha indandatho yamanzi noma ngaphansi kwamanzi (ukusika).

I-8, i-TPU (i-thermoplastic polyurethane elastomer), ukukhethwa okuningi kokushisa kwamanzi, kodwa ingxenye ye-extrusion metering yesiqondiso esifanayo kufanele ilungiswe ukuze kwakhiwe ingcindezi.

9. I-PET filament masterbatch, ingasikwa ngokubanda nge-drawbar (amanzi) noma i-cast strip cut ebandayo.#compounding twin screw extruder

10. Ukonga amandla kanye nokunciphisa ukukhishwa kwe-PPC (i-polypropylidene carbonate), ingahlanganiswa cishe nalo lonke uhlobo lwe-resin yokuwohloka (TPS, PLA, PBAT, PBS, PHBV, PHA, PVA, PCL, PGA) kanye ne-granulation ehlanganisiwe.
