Izinto Ezivamile Zepulasitiki Ezisetshenziswa Ekukhipheni Nezakhiwo Zazo

Ukukhetha ipulasitiki efanele kungenye yezinqumo ezibucayi kakhulu kwinqubo ye-extrusion. Kusukela ekuqineni kwesakhiwo kuye ekucaceni okubonakalayo, okokusebenza okukhethayo kunomthelela oqondile ekusebenzeni nasekuphileni komkhiqizo wakho wokugcina. Ukuqonda umehluko oyinhloko phakathi kwezinto ezivamile zepulasitiki ze-extrusion kungasiza abakhiqizi ukuthi benze izinqumo ezinolwazi, eziqondene nohlelo lokusebenza.

Ake sihlole izici ezibalulekile, izidingo zokucubungula, kanye nemithelela yokusetshenziswa kokugcina kwamapulasitiki asetshenziswa kakhulu ku-extrusion.

I-PVC: I-Versatility Ihlangana Nokumelana Kwamakhemikhali

I-Polyvinyl chloride (PVC) isetshenziswa kabanzi ngenxa yebhalansi yayo enhle kakhulu yezindleko, ukucutshungulwa, nokuqina. Itholakala ngamafomu aqinile futhi avumelana nezimo, i-PVC imelana namakhemikhali, ukuchayeka kwe-UV, kanye nomswakama, okuyenza ilungele amapayipi, amaphrofayili, nezinhlelo zokusebenza zangaphandle.

Ku-extrusion, i-PVC ivamise ukucubungula phakathi kuka-160°C no-210°C. Idinga iphrofayili yezinga lokushisa elawulwa ngokucophelela kanye nedizayini yesikulufu esekela ukuncibilika okuzinzile futhi egwema ukucekelwa phansi. Imvelo yayo evimbela amalangabi kanye nezakhiwo ezinhle zokufaka ugesi nakho kuyenza ikhetheke kakhulu ezinhlelweni zikagesi.

I-PE: I-Lightweight kanye ne-Impact-Resistant

I-Polyethylene (PE), ikakhulukazi ezinhlobonhlobo zayo ze-HDPE ne-LDPE, yaziwa ngokuguquguquka kwayo, ukumelana nomthelela, nokumunca umswakama ophansi. Yimpahla yokuya kumashubhu, amafilimu okupakisha, namapayipi amanzi.

I-PE ikhipha kahle ku-160–230°C, ngamadizayini ngezikulufu agcizelela ukushear okuphansi nokuphuma okuphezulu. Ukuqedwa kwayo okubushelelezi kanye nokumelana namakhemikhali okuhle kakhulu kuyenza ifanele ukuthuthwa kwamanzi kanye nezicelo zokuthintana nokudla. Phakathi kwazo zonke izinto zepulasitiki ze-extrusion, i-PE igqama ngokuqina kwayo okuhle kakhulu ezindaweni ezinokhahlo.

I-PP: Ukuzinza Kwekhemikhali Nokuqina

I-Polypropylene (PP) inikeza inhlanganisela eyingqayizivele yokuqina nokumelana namakhemikhali. Inephuzu lokuncibilika eliphakeme kune-PE futhi inikeza ukumelana nokukhathala okuphakeme, okuyenza ifaneleke izingxenye zezimoto, imishini yaselabhorethri, namahinge aphilayo.

I-PP icubungula emazingeni okushisa aphakeme kancane (200–280°C), futhi idinga isikulufu esinokuxuba okuqinile kanye nezindawo zokuminyanisa ukuze kuqinisekiswe ukugeleza kokuncibilika okufanayo. Futhi ayisindi futhi inokumelana okuhle nama-asidi nezisekelo, ilungele izindawo lapho ukuchayeka kwamakhemikhali kuvame.

I-ABS: Ukuqina Ngekhwalithi Yokuqedwa Okuphezulu

I-Acrylonitrile Butadiene Styrene (ABS) ikhethwa uma ukumelana nomthelela nokubukeka kwendawo kuyizidingo ezibalulekile. Ivamise ukutholakala ezimpahleni zabathengi nasezindlini zikagesi, i-ABS ihlanganisa ukuqina nokuzinza okuhle kohlangothi.

Ukukhipha i-ABS kudinga amazinga okushisa ebangeni elingu-190–240°C, ngesikrufu sesikulufu esimaphakathi ukugwema ukuphuzi noma ukonakala kwendawo. Nakuba i-ABS ingamelani ne-UV ngaphandle kwezithasiselo, isilinganiso sayo samandla nesisindo siyenza idume ezinhlelweni zokusebenza ezisebenza kahle kakhulu.

I-PC: I-Optical Clarity kanye nokumelana nokushisa

I-Polycarbonate (PC) ikhethwa ngokusobala, ukuqina kokushisa, namandla omthelela aphezulu. Ivamise ukusetshenziswa kumakhava okukhanyisa, amaphaneli okuvikela, namadivayisi ezokwelapha lapho ukucaca namandla kubaluleke kakhulu.

I-PC extrusion idinga amazinga okushisa aphakathi kuka-240–300°C kanye nesikulufu se-extruder se-torque ephezulu esinoshear olawulwayo. Phakathi kwezinto zepulasitiki ze-extrusion, i-PC idinga ukulawula izinga lokushisa okunembile ukugwema ukuphuzi noma ukubola. Ukucaca kwayo okubonakalayo kuyenza ibe ukukhetha okuphezulu ezinhlelweni ezidinga ukubonakala okuphezulu nokudluliswa kokukhanya.

Ukufanisa Impahla Nesicelo: Isihluthulelo Sempumelelo

Ukukhetha izinto zepulasitiki ezifanele zokukhishwa akukhona nje izindleko noma ukutholakala—kumayelana nokuvumelanisa izici zokusebenza nezidingo zohlelo lokusebenza. Udinga ukumelana okuphezulu kwe-UV ukuze usetshenziswe ngaphandle? I-PVC noma i-PE eyenziwe ngokukhethekile ingase ibe ngcono kakhulu. Ingabe ufuna amaphaneli acacile, ahlala isikhathi eside? Cabanga nge-PC. Eziqukathi ezimelana namakhemikhali, i-PP ingumdlali ophezulu.

Izinto zepulasitiki ze-extrusion ozikhethayo ngeke zinqume kalula ukucutshungulwa kuphela kodwa nempumelelo yesikhathi eside yomkhiqizo wakho ensimini.

Ingabe ufuna ukuthuthukisa umugqa wakho we-extrusion ngezinto ezifanele zepulasitiki? Xhuma ngeJWELLnamuhla—uzakwenu omethembayo kuzisombululo ezithuthukisiwe ze-extrusion nobungcweti bezinto ezibonakalayo.
