Yileyo ndlela yokuhlanza izinto zokukhipha izinto zepulasitiki, uyazi?

Namuhla, ngobuchwepheshe obuthuthukisiwe, ukuhlanza i-extruder yepulasitiki akuyona inkinga enkulu, kodwa indlela yokuhlanzai-extruder yepulasitikingendlela efanele futhi engabizi kakhulu ngaphandle kokulimala kwesikulufu nomgqomo kuyinkinga, futhi kuzoba yinkinga uma kwenziwa ngendlela engafanele noma kubangele inkinga enkulu. Namuhla, ake sixoxe ngendlela yokuhlanza kahle i-extruder yepulasitiki (ikakhulukazi isikulufu nomgqomo) ngenxa yawo wonke umuntu.

01. Ungasihlanza kanjani kahle isikulufu?

1) Khetha idivayisi yokushisa efanele

Ukusebenzisa umlilo noma umlilo ukususa ipulasitiki eboshwe esikulufini kuyindlela evame kakhulu futhi ephumelelayo yamayunithi okucubungula ipulasitiki, kodwa ilangabi le-acetylene akufanele lisetshenziswe ukuhlanza isikulufi. Izinga lokushisa lelangabi le-acetylene lingafinyelela ku-3000°C. Ukuhlanza isikulufi ngelangabi le-acetylene ngeke kubhubhise nje kuphela izici zensimbi zesikulufi, kodwa futhi kuzothinta kakhulu ukubekezelelana kwemishini kwesikulufi.

Uma ilangabi le-acetylene liphenduka umbala oluhlaza okwesibhakabhaka oqhubekayo lapho kubhakwa ingxenye ethile yesikulufu, kusho ukuthi isakhiwo sensimbi sale ngxenye yesikulufu sishintshile, okuzoholela ekunciphiseni ukumelana nokuguguleka kwale ngxenye, ngisho nokuvela kwengqimba yokumelana nokuguguleka kanye ne-matrix. Ukukhumula insimbi. Ngaphezu kwalokho, ukushisa kwendawo kwelangabi le-acetylene kuzophinde kubangele ukushisa kolunye uhlangothi lwesikulufu, okuzobangela ukuthi isikulufu sigobe. Izikulufu eziningi zenziwe ngensimbi engu-4140.HT enezimo eziqinile kakhulu, ngokuvamile ngaphakathi kuka-0.03mm.
Ukuqondile kwesikulufu kungaphakathi kakhulu kwe-0.01mm. Uma isikulufu sibhakwa futhi sipholiswa ilangabi le-acetylene, kuvame ukuba nzima ukubuyela ekuqondeni kwasekuqaleni. Indlela efanele nephumelelayo: sebenzisa i-blowtorch ukuhlanza isikulufu ngokushesha ngemva kokusebenzisa. Ngenxa yokuthi isikulufu sinokushisa ngesikhathi sokucubungula ngalesi sikhathi, ukusatshalaliswa kokushisa kwesikulufu kusafana.

2) Khetha i-ejenti yokuhlanza efanele

Namuhla, ngomnotho wezimpahla othuthuke kakhulu, kunezinhlobo eziningi zezihlanzi zezikulufo (izinto zokuhlanza izikulufo) emakethe, eziningi zazo ezibizayo futhi ezinemiphumela ehlukile. Ukuthi zizosetshenziswa yini izinto zokuhlanza zezentengiselwano kuncike kubakhiqizi abahlukene kanye nezimo zokukhiqiza; amabhizinisi okucubungula ipulasitiki angasebenzisa nama-resin ahlukene njengezinto zokuhlanza izikulufo ngokwezimo zawo zokukhiqiza, okungonga imali eningi yeyunithi.

3) Khetha indlela efanele yokuhlanza

Isinyathelo sokuqala sokuhlanza isikulufu ukuvala i-feeding insert, okungukuthi, ukuvala i-feeding port phansi kwe-hopper; bese wehlisa isivinini sesikulufu sibe ngu-15-25r/min, bese ugcina lesi sivinini kuze kube yilapho ukugeleza kokuncibilika ngaphambili kwe-die kuyeka ukugeleza kuze kube yilapho. Izinga lokushisa lazo zonke izindawo ezishisayo ze-barrel kufanele libekwe ku-200°C. Ukuhlanza kuqala ngokushesha nje lapho i-barrel ifika kuleli zinga lokushisa.
Kuye ngenqubo yokukhipha (idayi kungadingeka isuswe ukuze kuncishiswe ingozi yokucindezela ngokweqile engxenyeni engaphambili yedayi), ukuhlanza kumele kwenziwe ngumuntu oyedwa: umqhubi ubheka isivinini sesikulufu kanye ne-torque evela kuphaneli yokulawula, ngenkathi ebheka idayifu ukuqinisekisa ukuthi ingcindezi yesistimu ayibi phezulu kakhulu. Phakathi nayo yonke inqubo, isivinini sesikulufu kufanele sigcinwe ngaphakathi kwama-20r/min. Ezisetshenzisweni zedayifu eziphansi, ungayisusi idayisi ukuze uyihlanze kuqala. Misa ngokushesha idayifu bese ususa ikhanda ledayifu lapho idayifu iguqulwa ngokuphelele kusuka ku-process resin ibe yi-clean resin, bese uqala kabusha isikulufu (ngaphakathi kwama-10r/min) ukuze uvumele idayifu ehlanzekile esele iphume.

02. Ungawuhlanza kanjani kahle umgqomo?

Ukuhlanza ibhere kulula kakhulu kunokuhlanza isikulufu, kodwa futhi kubaluleke kakhulu.
1) Ekulungiseleleni ukuhlanza ibhereli, izinga lokushisa lebhereli nalo labekwa ku-200°C.
2) Bopha ibhulashi lensimbi eliyindilinga entongeni yokubhoboza kanye ne-drill kagesi bese ulifaka njengethuluzi lokuhlanza, bese ugoqa ibhulashi lensimbi nge-wire mesh yethusi.
3) Ngaphambi kokufaka ithuluzi lokuhlanza emgqonyeni, fafaza i-stearic acid ethile emgqonyeni, noma ufafaze i-stearic acid emshinini wethusi wensimbi yokuhlanza;
4) Uma i-copper wire mesh ingena emgqonyeni, qala i-electric drill ukuze ijikeleze, futhi ngesikhathi esifanayo ihambe iye emuva naphambili ngokwenziwa kuze kube yilapho ukunyakaza kwe-back and naphambili kukhululeka ekumelaneni;
5) Ngemva kokuba i-copper wire mesh isusiwe emgqonyeni, sebenzisa indwangu kakotini ukuze usule emuva naphambili emgqonyeni ukuze ususe noma iyiphi i-resin yokuhlanza noma i-fatty acid residue; ngemva kokusula okuningana okunjalo emuva naphambili, ukuhlanza umgqomo sekuqediwe. Kuhlanzwe kahleizikulufu nemiphongolosezilungele ukuhlanganiswa ukuze zisebenzele ukukhiqiza okulandelayo!
