Okokuqala, khetha idivayisi yokushisisa efanele
Ukukhipha ipulasitiki egxishwe kusikulufu ngomlilo noma ngokugazinga kuyindlela evamile nesebenzayo yamayunithi okucubungula epulasitiki, kodwa ilangabi le-acetylene akufanele nanini lisetshenziswe ukuhlanza isikulufu.
Indlela elungile nephumelelayo: sebenzisa i-blowtorch ngokushesha ngemva kokuba isikulufu sisetshenziselwe ukuhlanza. Ngenxa yokuthi isikulufu sinokushisa ngesikhathi sokucubungula, ukusatshalaliswa kokushisa kwesikulufu kusafana.
Okwesibili, khetha i-ejenti yokuhlanza efanele
Kunezinhlobo eziningi zokuhlanza izikulufu (izinto zokuhlanza izikulufu) emakethe, eziningi zazo ezibizayo futhi ezinemiphumela ehlukile. Izinkampani ezilungisa ipulasitiki zingasebenzisa ama-resin ahlukene ukwenza izinto zokuhlanza izikulufu ngokwemibandela yazo yokukhiqiza.
Okwesithathu, khetha indlela yokuhlanza efanele
Isinyathelo sokuqala sokuhlanza isikulufu ukuvala ukufaka okuphakelayo, okungukuthi, ukuvala imbobo yokudla ngaphansi kwe-hopper; Bese wehlisa isivinini sesikulufu sibe ngu-15-25r/min futhi ugcine lesi sivinini kuze kube yilapho ukugeleza kwencibilika ngaphambili kwefa kuyeka ukugeleza. Ukushisa kwazo zonke izindawo zokushisa zomgqomo kufanele kusethwe ku-200 ° C. Lapho nje umgqomo ufinyelela kulokhu kushisa, ukuhlanza kuqala.
Ngokuya ngenqubo ye-extrusion (ukufa kungase kudinge ukususwa ukuze kuncishiswe ingozi yokucindezela ngokweqile ekugcineni kwe-extruder), ukuhlanza kufanele kwenziwe ngumuntu oyedwa: opharetha ubheka isivinini se-screw kanye ne-torque kusuka kuphaneli yokulawula, ngenkathi ubheka ingcindezi ye-extrusion ukuze uqinisekise ukuthi ingcindezi yesistimu ayiphezulu kakhulu. Phakathi nayo yonke inqubo, isivinini se-screw kufanele sigcinwe ngaphakathi kwe-20r/min. Kuzicelo ezinomfutho ophansi ziyafa, ungasusi ukufa kokuhlanza kwasekuqaleni. Uma i-extrusion iguqulwa ngokuphelele kusukela ku-resin yokucubungula kuya ku-resin yokuhlanza, ukufa kuyamiswa futhi kukhishwe, bese isikulufu siqaliswa kabusha (ngaphakathi kwe-10r/min) ukuvumela inhlaka yokuhlanza esele ukuthi iphume.
Okwesine, khetha amathuluzi okuhlanza afanele
Amathuluzi afanele kanye nezinto zokuhlanza kufanele zifake: amagilavu angangeni ekushiseni, izibuko, ama-copper scrapers, amabhulashi ethusi, i-copper wire mesh, i-stearic acid, ama-drill kagesi, ama-barrel rula, indwangu kakotini.
Uma i-resin yokuhlanza iyeka ukuphuma, isikulufu singahoxiswa kudivayisi. Ngezikulufu ezinesistimu yokupholisa, susa ulayini wepayipi kanye noxhumano lwe-swivel ngaphambi kokuqala idivayisi yokukhipha isikulufu, okungenzeka inamathiselwe ku-gearbox. Sebenzisa idivayisi yokukhipha isikulufu ukuze uphushele isikulufu phambili, uveze indawo yezikulufu ezingu-4-5 ukuze zihlanzwe.
I-resin yokuhlanza ku-screw ingahlanzwa nge-scraper yethusi nebhulashi lethusi. Ngemuva kokuthi i-resin yokuhlanza kusikulufu esiveziwe isihlanziwe, idivayisi izophushelwa phambili izikulufu ezingu-4-5 kusetshenziswa idivayisi yokukhipha isikulufu bese iqhubeka nokuhlanza. Lokhu kwaphindwa futhi ekugcineni iningi lesikulufu laphushwa ngaphandle komgqomo.
Uma iningi leresin yokuhlanza selisusiwe, fafaza i-stearic acid kusikulufu; Bese usebenzisa i-copper wire mesh ukususa okusele, futhi ngemva kokuba isikulufu sonke sipholishwe nge-copper wire mesh, sebenzisa indwangu kakotini ukuze usule okokugcina. Uma isikulufu sidinga ukugcinwa, ungqimba lwamafutha kufanele lufakwe phezulu ukuze kuvinjelwe ukugqwala.
Ukuhlanza umgqomo kulula kakhulu kunokuhlanza isikulufu, kodwa futhi kubaluleke kakhulu.
1. Lapho ulungiselela ukuhlanza umgqomo, izinga lokushisa lomgqomo liphinde libekwe ku-200 ° C;
2. Khipha ibhulashi lensimbi eliyindilinga epayipini lokubhoboza kanye ne-drill kagesi ibe amathuluzi okuhlanza, bese usonga ibhulashi lensimbi nge-copper wire mesh;
3. Ngaphambi kokufaka ithuluzi lokuhlanza emgqonyeni, fafaza i-stearic acid emgqonyeni, noma ufafaze i-stearic acid enezintambo zethusi zethuluzi lokuhlanza;
4. Ngemuva kokuthi i-mesh yocingo lwethusi ingene emgqonyeni, qala umshini wokubhoboza kagesi ukuze uwujikeleze, futhi wenze ngokwenziwa ukuthi uhambe uye phambili kuze kube yilapho ukunyakaza okuya phambili nangemuva kungenakuphikiswa;
5. Ngemva kokuba i-mesh yocingo lwethusi isusiwe emgqonyeni, sebenzisa inqwaba yendwangu kakotini ukuze usule emuva naphambili emgqonyeni ukuze ususe noma iyiphi inhlaka yokuhlanza noma insalela ye-fatty acid; Ngemuva kokusula okuningana okunjalo emuva naphambili, ukuhlanzwa komgqomo kuqediwe. Isikulufu esihlanzwe kahle nomgqomo sekulungele ukukhiqizwa okulandelayo!
