Ngenxa yokuhanjiswa okuphezulu kwepulasitiki esobala, kunezidingo eziqinile ezisezingeni eliphezulu lemikhiqizo yepulasitiki, njengokungabi bikho kwamabala, awekho amaphethini, ama-porosity, amhlophe, imigqa enqenqemeni, amabala amnyama, ukuguquguquka kombala, ukucwebezela okungalingani, njll. epheleleukubumba umjovoinqubo, kufanele kube nezidingo eziqinile nezikhethekile zezinto zokusetshenziswa, izinto zokusebenza, isikhunta ngisho nokwakhiwa komkhiqizo.
Njengoba amapulasitiki asobala ngokuvamile anephuzu eliphakeme lokuncibilika kodwa ikhono lokugeleza elimpofu, ukulungisa i-coefficient yokushisa yomshini, ingcindezi yomjovo, nesivinini somjovo ukuze kuqinisekiswe izinga eliphezulu lingagcwalisa indawo yomjovo ngenkathi kunciphisa amathuba okukhiqiza ukucindezeleka kwangaphakathi futhi kubangele ukubola nokuqhekeka.Ngakho-ke, imisebenzi eqinile kufanele yenziwe ekulungiseleleni impahla eluhlaza, okokusebenza okunjengamakhithi okubumba epulasitiki acacile kanye nezidingo zokubunjwa komjovo, inqubo yokubumba umjovo kanye nokuphathwa kwemikhiqizo eluhlaza.Indlela yokwenza ipulasitiki ebonakalayo ngokucacile?Nazi ezinye izici okufanele uzazi:
1. Ukulungisa nokomisa izinto ezingavuthiwe
Njengoba ukungcola okuncane epulasitiki kuzothinta ukubonakala komkhiqizo, umkhiqizo kufanele uvalwe kahle ngesikhathi sokugcinwa, ukuthutha kanye nokudla ukuze kuqinisekiswe ukuthi umkhiqizo uhlanzekile, ikakhulukazi impahla eluhlaza kulula ukuwohloka ngemva kokushisa.Kunomswakama omncane, ngakho kufanele womiswe elangeni.Ngaphezu kwalokho, i-hopper idinga ukumiswa lapho isondla.Futhi, umoya ongenayo kufanele uhlungwe futhi ususwe umswakama phakathi nenqubo yokomisa ukuze kuqinisekiswe ukuthi awungcolisi impahla eluhlaza.
2.Ukuhlanzwa komgqomo, isikulufu nezinye izesekeli
Ukuvimbela ukungcoliswa kwezinto zokusetshenziswa kanye nezinsalela ezifihliwe noma ukungcola endaweni yezesekeli, ikakhulukazi i-resin enokuqina okushisayo okushisayo, ipulasitiki esikhunjeni kanye nesikulufu somshini kufanele ihlanzwe ngama-ejenti okuhlanza ukuze kususwe ngokuphelele ukungcola, noma ku-screw. ukungabikho kwama-agent okuhlanza isikulufa, sebenzisa i-PE, i-PS namanye ama-resin ukuhlanza isikulufu.Lapho kuvalwe kungazelelwe, ukuze kuvinjwe ukubola kwezinto zokusetshenziswa emazingeni okushisa aphezulu isikhathi eside, izinga lokushisa le-dryer kanye nomgqomo kufanele lincishiswe, njenge-PC, izinga lokushisa lomgqomo we-PMMA kufanele libe ngaphansi kwama-degrees ayi-160 (izinga lokushisa le-hopper kufanele lincishiswe. yehliswe ibe ngaphansi kwe-100 degrees PC).
3.Umklamo wesikhunta womjovo kufanele unake amaphuzu alandelayo (kuhlanganise nomklamo womkhiqizo)
Amaphuzu alandelayo kufanele aqashelwe lapho uklama isikhunta somjovo ukuvimbela ukubumba kwepulasitiki okubi, ukonakala kwendawo kanye nokonakala okubangelwa ukugeleza kabusha okungalungile noma ukupholisa okungalingani.
a) Ubukhulu bodonga kufanele bulingane ngangokunokwenzeka futhi ukuthambekela okusalungiswa kwesikhunta kufanele kube kukhulu ngangokunokwenzeka.
b) Ushintsho kufanele lube mnene futhi lube bushelelezi ukuvimbela amakhona abukhali nemiphetho ebukhali, ikakhulukazi kumikhiqizo ye-pc, futhi akufanele kube nezikhala.
c) Isango: Umgijimi kufanele abe banzi futhi abe mfushane ngangokunokwenzeka, futhi indawo yesango kufanele ihambisane nenqubo yokushwabana.Impahla ebandayo iyadingeka uma kunesidingo.
d) Indawo yokubunjwa yomjovo kufanele ibe bushelelezi ibe nobulukhuni obuphansi (ubukhulu obunguRa0.8)
e)Inombolo yemigodi yokukhipha umoya kanye nezikhala zokukhipha umoya kufanele zanele ukukhipha umoya negesi ekuncibilikeni.
f) Ubukhulu bodonga akufanele bube buncane kakhulu ngaphandle kwezinto ze-PET, ngokuvamile bungabi ngaphansi kuka-1mm.
Khuluma nathi mayelana nephrojekthi yakho entsha, ukubonisana kwamahhala kanye ne-DFM yamahhala
