Izindaba

Cacisa isikulufu esisodwa se-granulation ngalolu hlelo: i-feedstock, ukulungiswa kwe-ncibilikisa okudingekayo, umthwalo wokukhipha umoya, umsebenzi wokuxutshwa, ukumelana nokuhlunga kanye nendlela yokugaya. Yisho ukuthi ingabe okuphakelayo kuyi-pellet ehlanzekile, impushana, i-agglomerate, i-flake egeziwe noma umfudlana oguquguqukayo ogaywe kabusha. Nikeza ibanga le-resin, isimo sokuhlolwa kwe-MFR, umswakama, ukungcoliswa, isigcwalisi, ukuphuma okuqondiwe, i-motor, i-rpm, ukuhlelwa kwe-vacuum nezimpawu zamanje. Isikulufu singabe sesiklanywa sizungeze iwindi lempahla yangempela esikhundleni sobubanzi obungajwayelekile.

Khetha isikulufu esivuthela ifilimu ngalolu hlelo: i-resin kanye nokwakheka, ifilimu eqediwe nesakhiwo sesendlalelo, umsebenzi womugqa, bese ujika ijiyomethri ngesikulufu nohlelo lwangaphezulu. Buza izinga eliqondile le-resin nesimo sokuhlola ukugeleza kwe-ncibilika, hhayi kuphela i-“LDPE,” “LLDPE” noma “i-HDPE.” Rekhoda isilinganiso senhlanganisela, izithasiselo, okuqukethwe okugaywe kabusha, okukhiphayo, isivinini sesikulufu, i-motor, die, ububanzi befilimu nobubanzi bokujiya. Kulapho-ke kuphela lapho nquma khona ububanzi, i-L/D, ukujula kokuphakelayo, iphrofayili yokuncibilika, ingxenye yemitha kanye nokuthi ingxenye yokuvimbela noma yokuxuba ifanelekile yini.

Linganisa ukuguga njengepheya elisuselwe endaweni, hhayi njengobubanzi besikulufa esisodwa. Maka iziteshi ze-axial ngokuphakelayo, ukucindezela kanye nezindawo zamamitha. Esiteshini ngasinye, rekhoda indiza eyisikulufu ngaphandle kwedayamitha kanye nomphongolo ongaphakathi ububanzi ngezindlela eziningi ezingama-angular. Bese ubala imvume ye-diametral ne-radial ngokwehlukana. Qhathanisa imephu nomdwebo wokuqala ovunyelwe noma inkomba yomklamo okuvunyelwene ngayo ngokucacile. Uma unezingxenye ezigugile kuphela, bhala imiphumela njengedatha yesimo. Ungazethuli njengobukhulu bangempela.

Shintsha isikulufu kuphela uma kulinganiswa umbhobho, ukuzungeza, isimo esingaphezulu nokuqondanisa kuhlala kusilungele isikulufu esisha esihlongozwayo. Shintshanisa zombili izingxenye lapho umgqomo ukhulisiwe, u-oval, ugezwa endaweni, wathola amaphuzu noma ugqwalile ngokwanele ukuthi isikulufu esisha sisazosebenza ngokukhululeka ngokweqile noma okungalingani. Uma ungenazo izilinganiso ezibhorekile, ungaqageli. Indawo yethu yefekthri ilula: ikhotheshini yesikulufu kuphela akufanele ithathwe njengesincomo esiphelele sobuchwepheshe kuze kube yilapho isimo somphongolo sesihloliwe.

Khetha isikulufu esivamile sokuphakelayo kwe-pellet okuzinzile, okufanayo kanye nokukhiphayo okusesilinganisweni lapho ukusebenza okulula kuyizinto eziza kuqala. Khetha isikulufu sokuvimbela lapho ulayini udinga ukuncibilika okuphelele kakhulu nokuphumayo okuzinzile ngamanani aphezulu, ikakhulukazi ku-PE ne-PP. Khetha isikulufu sokuxuba uma izinga lokushisa elincibilikayo lifana, ukusatshalaliswa kombala noma ukuhlakazeka okungeziwe kuyinkinga enkulu. Imisebenzi yokuvimbela kanye nokuxuba ayihlukanisi. Isikulufu esisodwa sephaneli ye-aluminium-plastic ye-Nanhaiya, isibonelo, sisebenzisa isigaba sokuxuba sohlobo lwesithiyo ukuze sisekele ukuncibilika, ukufana kwezinga lokushisa elincibilikayo kanye nokusatshalaliswa kombala nezinqamuleli zomlilo.

I-screw extruder eyodwa iyakhuphuka lapho okubalulekile kugeleza emugqeni kuyeka ukuzinza. Imithombo evamile ihlanganisa ukuphakela okungahambisani, ukuhluka kwesivinini sesikulufu, izinga lokushisa lomphongolo elingazinzile, ukuncibilika okungaphelele noma okungazinzile, umkhawulo oshintshayo wesikrini noma ukufa, ukuguga kwesikulufu nomgqomo, nokuhluka kwesivinini esingezansi komfula. Rekhoda ukucindezela kokuncibilika, amandla emoto, isivinini sesikulufu, amazinga okushisa wendawo, izinga lokuphakelayo kanye nesivinini esingezansi komfula emugqeni wesikhathi ofanayo ngaphambi kokushintsha izilungiselelo. Uma ukucindezela nokuphumayo kuhamba ndawonye, ​​phenya i-extruder nendlela yokugeleza. Uma amathrendi e-extruder ehlala ezinzile ngenkathi umkhiqizo ushintsha, qala ngefayizi, ukupholisa, i-vacuum, ukukhipha noma i-winder.
