Ingxaki yokushwabana kwamalungu adityanisiweyo enaliti esebenzayo (ukuncipha komphezulu kunye nokushwabana kwangaphakathi) ngokuqhelekileyo sisiphene esibangelwa kukunganyibiliki ngokwaneleyo xa iindawo ezishinyeneyo nezinkulu zipholile.Ngamanye amaxesha sidibana nemeko yokuba kungakhathaliseki indlela yokunyusa uxinzelelo, ukwandisa ukungena kwamanzi, kunye nokwandisa ixesha lokujova, ingxaki yokunciphisa ayinakusombululeka.Namhlanje, uXiaowei angathanda ukuxoxa nawe malunga nendlela yokujongana nengxaki yokushwabana kwamalungu abunjiweyo.
1. Iimeko ezimbini zokushisa ezingenakuncedo ekusombululeni ingxaki ye-shrinkage kwinkqubo yokubumba isitofu
Ubushushu obuphantsi kakhulu bokungunda akuncedi ukusombulula ingxaki yokushwabana
Ingxaki ye-shrinkage yamacandelo eplastiki enzima (i-surface shrinkage kunye ne-internal shrinkage cavity) ibangelwa ukuba indawo eshiywe yi-shrinkage egxininisiweyo ayikwazi ukuzaliswa ngokupheleleyo ngokunyibilika ukusuka kwicala lokungena kwamanzi xa i-melt iyancipha xa ipholile.Ke ngoko, izinto ezingasincediyo ukondla ziya kusichaphazela ukucombulula ingxaki yokuncipha.
Ukuba iqondo lobushushu lokungunda liphezulu kakhulu, kulula ukubangela iingxaki zokuncipha.Ngokuqhelekileyo, abantu bathanda ukuthoba iqondo lokushisa lokungunda ukusombulula ingxaki.Kodwa ngamanye amaxesha ukuba ukushisa kwe-mold kuphantsi kakhulu, akufanelekile ukusombulula ingxaki yokunciphisa, engabonakali ngabantu abaninzi.
Iqondo lokushisa lokungunda liphantsi kakhulu, iglue enyibilikisiweyo iphola ngokukhawuleza kakhulu, kwaye indawo yeglue engqindilili kancinci kude ukusuka kwindawo yokungena amanzi, kuba indawo ephakathi iphola ngokukhawuleza, umjelo wokutya uvaliwe, kwaye iglu enyibilikisiweyo ayinakunyibilika ngokupheleleyo. umgama.Ukongezwa, okwenza ukuba ingxaki yokushwabana kube nzima ngakumbi ukuyisombulula, ngakumbi ingxaki yokushwabana kwamalungu ajiyileyo namakhulu abunjiweyo.
Ngaphaya koko, iqondo lobushushu lokungunda lisezantsi kakhulu, nto leyo engabangeli ukonyusa ukucutheka okupheleleyo kweendawo ezibunjiweyo zenaliti, ukonyusa ukushwabana okugxininisiweyo, kwaye ingxaki yokushwabana imbi kakhulu kwaye icacile.
Ke ngoko, xa usombulula ingxaki enzima yokuncipha, kuya kuba luncedo ukukhumbula ukujonga ubushushu bokubumba.Amagcisa anamava adla ngokuchukumisa umphezulu womgodi wokungunda ngezandla ukuze abone ukuba kubanda kakhulu okanye kushushu kakhulu.Imathiriyeli ekrwada nganye inobushushu bayo bokungunda obufanelekileyo.
2. Ubushushu bokunyibilika obuphantsi kakhulu kwinkqubo yokubumba yokutofa akuncedi ukusombulula ingxaki yokushwabana.
Ukuba iqondo lobushushu lokunyibilika liphezulu kakhulu, iindawo ezibunjiweyo zenaliti zithande ukushwabana.Ukuba iqondo lokushisa lihla ngokufanelekileyo nge-10 ~ 20 ° C, ingxaki yokunciphisa iya kuphuculwa.
Nangona kunjalo, ukuba isitofu esibunjiweyo sicutheka kwindawo engqindilili, hlengahlengisa ubushushu obunyibilikayo busezantsi kakhulu, umzekelo, xa isondele kumda osezantsi wokunyibilika kwenaliti, ayilungele ukusombulula ingxaki yokuncipha, kwaye nangaphezulu. nzulu.Okukhona iqhekezana lijiyile, kokukhona licaca ngakumbi.
Isizathu siyafana neso seqondo lobushushu lokungunda lisezantsi kakhulu.I-glue etyhidiweyo idibanisa ngokukhawuleza, kwaye umehluko omkhulu weqondo lokushisa ohambelana nokutya awukwazi ukubunjwa phakathi kwendawo eyanciphayo kunye nombhobho.Umjelo wokutya kwindawo yokuncipha uya kuvalwa ngaphambi kwexesha, kwaye ingxaki isonjululwe.kuba nzima ngakumbi.Kwakhona kunokubonwa ukuba ukukhawuleza kwesantya se-condensation yeglue enyibilikayo, kuya kuba lula ukusombulula ingxaki yokuncipha.Imathiriyeli yePC yimathiriyeli ekrwada ejiya ngokukhawuleza, ngoko ke ingxaki yayo yomgodi wokushwabana kunokuthiwa yingxaki enkulu ekubumbeni inaliti.
Ukongeza, iqondo lobushushu eliphantsi kakhulu lokunyibilika alibancedisi ukunyusa umlinganiselo wokushwabana ngokubanzi, nto leyo ekhokelela ekwandeni komlinganiselo wokushwabana okugxininisiweyo, ngaloo ndlela kuyenza ibe mandundu ingxaki yokuncipha.
Ke ngoko, xa uhlengahlengisa umatshini ukusombulula ingxaki enzima yokuncipha, kubaluleke kakhulu ukujonga ukuba iqondo lobushushu lokunyibilika lilungelelaniswe phantsi kakhulu.
Kuyaqondakala ngakumbi ukujonga ubushushu kunye nolwelo lokunyibilika.
3. Isantya sokutofa esikhawulezayo asincedi ukusombulula ingxaki yokushwabana okumandundu
Ukusombulula ingxaki yokuncipha, into yokuqala ethi qatha engqondweni kukunyusa uxinzelelo lwenaliti kunye nokwandisa ixesha lokutofa.Kodwa ukuba isantya senaliti silungelelaniswe ngokukhawuleza okukhulu, akuncedi ukusombulula ingxaki yokushwabana.Ngoko ke, xa i-shrinkage inzima ukuphelisa, kufuneka isonjululwe ngokunciphisa isantya sokujova.
Ukunciphisa isantya sokutofa kungenza umahluko omkhulu wobushushu phakathi kweglu enyibilikisiweyo ehamba ngaphambili kunye nendawo yokungena yamanzi, enceda ukuqiniswa okulandelelanayo kunye nokutya kweglu etyhidiweyo ukusuka kude ukuya kufutshane, kwaye ikwanceda kwindawo yokucutheka kude. ukusuka emlonyeni.Ukufumana izongezo zoxinzelelo oluphezulu kunokuhamba indlela ende ekusombululeni ingxaki.
Ngenxa yokwehliswa kwesantya sokutofa, iqondo lobushushu leglu enyityilisiweyo ngaphambili lisezantsi, kwaye isantya siye sacotha, kwaye icandelo lokubumba lokutofa akulula ukuvelisa umphetho obukhali, kwaye uxinzelelo kunye nexesha kunokubakho. inyuswe kwaye inde, nto leyo eluncedo ngakumbi ekuSombululeni ingxaki yokushwabana okumandundu.
Ukongezelela, ukuba inqanaba lokugqibela lokuzaliswa kokugqibela kunye nesantya esincinci, uxinzelelo oluphezulu kunye nexesha elide kunye nendlela yokubamba ingcinezelo yokunciphisa ngokukhawuleza kunye noxinzelelo iyamkelwa, umphumo uya kubonakala ngakumbi.Ngoko ke, kukwayindlela efanelekileyo yokusebenzisa le ndlela ukusuka kwinqanaba lokugqibela lokutofa xa kungenakwenzeka ukusebenzisa inaliti yesantya esicothayo ekuqaleni.
Nangona kunjalo, kuyafaneleka ukukhumbuza ukuba ukuzaliswa kucotha kakhulu, kodwa akunakulungele ukusombulula ingxaki yokuncipha.Ngenxa yokuba xa i-cavity igcwele, inyibilika ingumkhenkce ngokupheleleyo, njengokuba iqondo lokushisa elinyibilikayo liphantsi kakhulu, akukho khono lokondla i-shrinkage kude.
