Intshayelelo yePlastiki Extrusion
Ukukhutshwa kweplastiki yenye yezona nkqubo zisetyenziswa kakhulu kwishishini leplastiki, ngakumbi kwi-thermoplastics. Ngokufana nokubumba inaliti, i-extrusion iqeshwe ukwenza izinto ezineprofayili eqhubekayo, njengemibhobho, i-tubing, kunye neeprofayili zocango. I-extrusion ye-thermoplastic yanamhlanje ibe sisixhobo esomeleleyo malunga nenkulungwane, ivumela ukuveliswa komthamo ophezulu weendawo zeprofayili eziqhubekayo. Abathengi basebenzisana neenkampani zeplastiki zokukhupha iiplastiki ukuphuhlisa iiplastiki ezilungiselelwe iimfuno zabo ezithile.
Eli nqaku lihlalutya kwizinto ezisisiseko ze-plastic extrusion, ichaza indlela inkqubo esebenza ngayo, apho izinto ze-thermoplastic zinokukhutshwa, zeziphi iimveliso eziqhelekileyo ziveliswa nge-plastiki extrusion, kunye nendlela i-extrusion yeplastiki ithelekisa ngayo ne-aluminium extrusion.
Inkqubo yePlastiki yokuKhulisa
Ukuqonda inkqubo yeplastiki ye-extrusion, kubalulekile ukwazi ukuba yintoni i-extruder kunye nendlela esebenza ngayo. Ngokuqhelekileyo, i-extruder iquka la macandelo alandelayo:
IHopper: Igcina imathiriyeli yeplastiki ekrwada.
Ukutya Umqala: Utyisa iplastiki ukusuka kwihopha ukuya emgqomeni.
Umgqomo oshushu: Inesikrufu esiqhutywa yinjini, esityhala izinto eziya kukufa.
I-Breaker Plate: Ixhotyiswe ngesikrini sokucoca izinto kunye nokugcina uxinzelelo.
Umbhobho wokutyisa: Uhambisa izinto ezinyibilikisiweyo ukusuka kumgqomo ukuya kwidiyethi.
Die: Ibumba imathiriyeli kwiprofayile oyifunayo.
Inkqubo yokupholisa: Iqinisekisa ukuqina okufanayo kwenxalenye ekhutshiweyo.
Inkqubo yeplastiki ye-extrusion iqala ngokuzalisa i-hopper ngezinto eziqinileyo, ezifana neepellets okanye iiflakes. Izinto eziphathekayo zondliwa ngomqala wombhobho we-extruder. Njengoko izinto zingena kwi-barrel, ifudumeza kwiindawo ezininzi zokufudumeza. Kwangaxeshanye, izinto eziphathekayo zityhalelwa ngakwisiphelo sombhobho ngesikrufu esibuyiselayo, esiqhutywa yinjini. Isikrufu kunye noxinzelelo zivelisa ubushushu obongezelelweyo, ngoko ke iindawo zokufudumeza akufuneki zibe shushu njengobushushu bokugqibela bokukhutshwa.
Iplastiki etyhidiweyo iphuma kwi-barrel ngesikrini esiqiniswe yi-plate ye-breaker, esusa ukungcola kunye nokugcina uxinzelelo olufanayo ngaphakathi kombhobho. Izinto ke zidlula kumbhobho wesondlo kwifa yesiko, enendawo yokuvula emile njengeprofayili efunwayo ekhutshiweyo, evelisa iplastiki yesiko.
Njengoko izinto eziphathekayo zinyanzeliswa ngokufa, zithatha ubume bokuvulwa kwefa, ukugqiba inkqubo ye-extrusion. Iprofayili ekhutshiweyo ke ipholiswe kwindawo yokuhlambela amanzi okanye ngoluhlu lwemiqulu yokupholisa ukuze iqiniswe.
Iiplastiki ze-Extrusion
I-extrusion yeplastiki ifanelekile kwizinto ezahlukeneyo ze-thermoplastic, zifudunyezwe kwiindawo ezinyibilikayo ngaphandle kokubangela ukuthotywa kwe-thermal. Ubushushu be-extrusion buhluka ngokuxhomekeke kwiplastiki ethile. Iiplastiki eziqhelekileyo ze-extrusion ziquka:
I-Polyethylene (PE): Ikhupha phakathi kwe-400 ° C (ubuninzi obuphantsi) kunye ne-600 ° C (ubuninzi obuphezulu).
IPolystyrene (PS): ~450°C
Inayiloni: 450°C ukuya kuma-520°C
Ipolypropylene (PP): ~450°C
IPVC: Phakathi kwe-350°C kunye ne-380°C
Kwezinye iimeko, i-elastomers okanye iiplastiki ze-thermosetting zinokukhutshwa endaweni ye-thermoplastics.
Ukusetyenziswa kwePlastiki Extrusion
Iinkampani zePlastiki ze-extrusion zinokwenza uluhlu olubanzi lwamalungu aneprofayili engaguqukiyo. Iiprofayili zePlastiki ze-extrusion zilungele imibhobho, iiprofayili zocango, iinxalenye zeemoto, kunye nokunye.
1. Imibhobho kunye neTubing
Imibhobho yePlastiki kunye netyhubhu, ehlala yenziwe kwi-PVC okanye enye i-thermoplastics, zizicelo eziqhelekileyo zeplastiki ye-extrusion ngenxa yeeprofayili zazo ezilula ze-cylindrical. Umzekelo yimibhobho yokuhambisa amanzi akhutshiweyo.
2. I-Insulation yocingo
Uninzi lwe-thermoplastics lubonelela ngokugqwesileyo kokufakelwa kombane kunye nokuzinza kwe-thermal, kubenza bafanelekele ukukhupha i-insulation kunye ne-sheathing yeengcingo kunye neentambo. IiFluoropolymers nazo zisetyenziselwa le njongo.
3. IiProfayili zomnyango kunye neefestile
Iifestile zeplastiki kunye neefestile, ezibonakaliswe ngeeprofayili zazo eziqhubekayo kunye nobude, zifanelekile kwi-extrusion. I-PVC yinto eyaziwayo yesi sicelo kunye nezinye izincedisi zendlu ezinxulumene neeprofayili zeplastiki ze-extrusion.
4. Iimfama
Iimfama, ezibandakanya ii-slats ezininzi ezifanayo, zinokukhutshwa kwi-thermoplastics. Iiprofayili zidla ngokuba mfutshane, ngamanye amaxesha zinecala elinye elingqukuva. I-Polystyrene isoloko isetyenziselwa iimfama zomthi.
5. Ukuhluthwa kweMozulu
Iinkampani zePlastiki ze-extrusion zihlala zivelisa iimveliso zokuqhawula imozulu, eziyilelwe ukuba zilingane ngokufanelekileyo kumnyango kunye neefreyimu zefestile. Irabha yinto eqhelekileyo yokuhluthwa kwemozulu.
6. I-Windshield Wipers kunye ne-Squeegees
Iiwiper ze-Automotive windshield zidla ngokukhutshwa. Iplastiki ekhutshiweyo ingaba yimpahla yerabha yokwenziwa njenge-EPDM, okanye indibaniselwano yerabha yokwenziwa kunye neyendalo. Amagqabi e-Manual squeegee asebenza ngokufanayo kwiiwiper ze-windshield.
Ukukhutshwa kwePlastiki vs. I-Aluminiyam Extrusion
Ngaphandle kwe-thermoplastics, i-aluminiyam inokukhutshelwa kwakhona ukwenza iinxalenye zeprofayili eziqhubekayo. Izinto ezilungileyo ze-aluminium extrusion ziquka ukukhanya, ukuqhuba, kunye nokuphinda kusetyenziswe. Ukusetyenziswa okuqhelekileyo kwe-aluminium extrusion kubandakanya imivalo, iityhubhu, iingcingo, imibhobho, iingcingo, iileyili, iifreyimu, kunye neesinki zobushushu.
Ngokungafani ne-plastiki extrusion, i-aluminium extrusion ingaba ishushu okanye ibanda: i-extrusion eshushu yenziwa phakathi kwe-350 ° C kunye ne-500 ° C, ngelixa i-extrusion ebandayo yenziwa kwiqondo lokushisa.
Ukuqukumbela
I-extrusion yePlastiki, ngokukodwa kumxholo we-China Plastic Pipe Extrusion Line, yindlela eguquguqukayo kunye nesebenzayo yokuvelisa iinxalenye zeprofayili eziqhubekayo. Ukukwazi kwayo ukuphatha iintlobo ngeentlobo ze-thermoplastics kunye noluhlu olubanzi lwezicelo lwenza ukuba lube yimfuneko kwishishini lokwenziwa kweplastiki.
