Umthelela Wokukhetha Okubalulekile Ekusebenzeni Kwe-Plastiki Extruder: Ukukhetha I-resin Elungile

Isingeniso

Ukukhethwa kwe-resin kungaba nomthelela omkhulu ekusebenzeni kwe-extruder yepulasitiki. I-resin efanele ingasiza ekuthuthukiseni ikhwalithi yomkhiqizo okhishiwe, ikhulise ukusebenza kahle kokukhiqiza, futhi inciphise izindleko. Kulokhu okuthunyelwe kwebhulogi, sizoxoxa ngezinye zezinto okufanele uzicabangele lapho ukhetha i-resin ye-extruder yepulasitiki.

Izinto ezibonakalayo

Isinyathelo sokuqala ekukhetheni i-resin ukucabangela izakhiwo ezibonakalayo ezidingekayo ekufakweni. Ezinye zezinto ezibalulekile zifaka:

• Amandla:Amandla e-resin azonquma ukuthi singakanani isisindo somkhiqizo okhishiwe ongasisekela.
• Ukuqina:Ukuqina kwe-resin kuzonquma ukuthi umkhiqizo okhishiwe uzophambuka kangakanani ngaphansi komthwalo.
• Ukumelana nomthelela:Ukumelana komthelela we-resin kuzonquma ukuthi umkhiqizo okhishiwe uzomelana kanjani nokuwa noma ukushaywa.
• Ukumelana nezinga lokushisa:Ukumelana nezinga lokushisa kwe-resin kuzonquma ukuthi umkhiqizo okhishiwe uzomelana kanjani nokushisa.
• Ukumelana namakhemikhali:Ukumelana kwamakhemikhali kwe-resin kuzonquma ukuthi umkhiqizo okhishiwe uzomelana kahle kangakanani nokuchayeka kumakhemikhali.

Ukucubungula Ukucatshangelwa

Ngaphezu kwezakhiwo zezinto ezibonakalayo, kubalulekile ukucabangela ukucatshangelwa kokucubungula lapho ukhetha i-resin. Ezinye zezinto ezibalulekile zokucubungula zihlanganisa:

• I-Melt flow index (MFI):I-MFI iyisilinganiso sokuthi i-resin igeleza kalula kanjani lapho incibilikiswa. I-MFI ephezulu izoholela emazingeni okukhipha ngokushesha.
• I-Viscosity:I-viscosity ye-resin isilinganiso sokuthi i-resin imelana kangakanani nokugeleza. I-viscosity ephansi izoholela ekucubunguleni okulula.
• Izinga lokushisa lengilazi (Tg):I-Tg izinga lokushisa lapho inhlaka ishintsha khona isuka kokuqinile, into ephukayo iye kwethambile, eyirabha. Izinga lokushisa lokucubungula kufanele libe ngaphezu kwe-Tg ukuze inhlaka igeleze kahle.

Ukuhambisana Nezithasiselo

Amanye ama-resin ahambisana nezithasiselo ezingathuthukisa ukusebenza kwawo. Ezinye izengezo ezivamile zihlanganisa:

• Ama-Fillers: Ama-Filler angasetshenziswa ukuthuthukisa amandla, ukuqina, kanye nokuzinza kwe-dimensional yomkhiqizo okhishiwe.
• Ukuqinisa: Ukuqinisa, njengemicu yengilazi noma i-carbon fibers, kungasetshenziswa ukuthuthukisa amandla nokuqina komkhiqizo okhishiwe.
• Izingulube: Izingulube zingasetshenziswa ukwengeza umbala kumkhiqizo okhishiwe.
• Iziqinisi ze-UV: Iziqinisi ze-UV zingasetshenziswa ukuvikela umkhiqizo okhishwe emisebeni ye-UV.

Izindleko

Izindleko ze-resin ngesinye isici esibalulekile okufanele sicatshangelwe. Ama-resin angahluka ngentengo ukusuka kumadola ambalwa ngephawundi ukuya kumakhulu amadola ngephawundi. Izindleko ze-resin zizoncika ezintweni ezibonakalayo, ukucatshangelwa kokucubungula, nokuhambisana nezithasiselo.

Isiphetho

Ukukhethwa kwe-resin kuyisinqumo esibucayi esingaba nomthelela omkhulu ekusebenzeni kwe-extruder yepulasitiki. Ngokucabangela ngokucophelela izakhiwo zezinto ezibonakalayo, ukucubungula ukucatshangelwa, ukuhambisana nezithasiselo, kanye nezindleko, ungakhetha inhlaka elungile yohlelo lwakho lokusebenza.
