Umgomo wokuqamba wokubumba

Umklamo wokwakha isikhunta se-vacuum ufaka usayizi we-batch, imishini yokubumba, izimo zokuqonda, ukwakheka kwejometri, ukuqina kobukhulu nekhwalithi yaphezulu.

1. Usayizi we-batch usetshenziselwa izivivinyo. Lapho ukuphuma kwesikhunta kuncane, kungenziwa ngokhuni noma nge-resin. Kodwa-ke, uma isikhunta sokuhlola sisetshenziselwa ukuthola idatha nge-shrinkage, ukuqina kwesilinganiselo, kanye nesikhathi somjikelezo womkhiqizo, kufanele kusetshenziswe isikhulela esisodwa sethambo sesilingo futhi singasetshenziswa ngaphansi kwezimo zokukhiqiza. Ngokuvamile izinkomba zenziwe nge-gypsum, ithusi, i-aluminium noma i-aluminium-iron alloys, futhi ama-aluminium-resins awasetshenziswa kakhulu.

2, ukwakheka kwesimo sejometri, idizayini, imvamisa kufanele icabangele ukuqina kobukhulu kanye nekhwalithi yaphezulu. Isibonelo, ukwakheka komkhiqizo kanye nokuqina kwesilinganiso kudinga ukusetshenziswa kokhuba lowesifazane (isikhunta sowesifazane), kepha ingaphezulu lidinga umkhiqizo ophakeme kakhulu, kepha lidinga ukusetshenziswa kwesikhunta sowesilisa (protrusion), ukuze izingxenye zepulasitiki ezihlelayo zicabange lawa maPhuzu amabili ukuze umkhiqizo ukhiqizwe ngaphansi kwezimo ezifanele. Isipiliyoni sikhombisile ukuthi imiklamo engahlangabezani nezimo zangempela zokusebenzisa ivame ukwehluleka.

3, ubukhulu buzinzile, kwinqubo yokubumba, indawo engxenyeni yepulasitiki ehlangene nesikhunta ingcono kunokuqina kobukhulu bengxenye eshiya isikhunta. Uma ubukhulu bokwenyama budingeka ukuthi buguquke ngokuzayo ngenxa yobulukhuni bezinto ezibonakalayo, kungahle kuholele ekuguqulweni kobumba lowesilisa lube lukhuni lowesifazane. Ukubekezelelwa kobukhulu kwengxenye yepulasitiki akunakuba ngaphansi kwamaphesenti ayi-10 esilinganiso se-shrinkage.

4. Ingaphezulu lengxenye yepulasitiki. Ngokuya ebangeni lapho izinto zokubumba zingasongwa khona, isendlalelo sendawo ebonakalayo yengxenye yepulasitiki kufanele sakhiwe lapho sithintana nesikhunta. Uma kungenzeka, uhlangothi oluhlanzekile lwengxenye yepulasitiki akufanele luhlangane nendawo yokubumba. Kufana nokusebenzisa isikhunta sowesifazane ukwenza ishubhu kanye neshubhu lokuwasha.

I-5, ukuguqulwa, uma usebenzisa i-saw enomshini ovundlile ukubona uhlangothi lomphetho lwezingxenye zepulasitiki, endaweni ephakeme, okungenani i-6 ~ 8mm yebhalansi. Eminye imisebenzi yokuqeda, njengokugaya, ukusika i-laser noma ijeet, kufanele futhi kushiye umugqa. Igebe eliphakathi kwezintambo zokusika zommese lincane kunazo zonke, futhi ububanzi bokusabalalisa lapho kufa kukwembiwa kususwe nakho kubuncane, okumele kuphawulwe.

I-6, i-shrinkage kanye ne-deformation, i-shrinkage yepulasitiki (efana ne-PE), ezinye izingxenye zepulasitiki kulula ukuzonakalisa, noma ngabe zivinjelwa kanjani, izingxenye zepulasitiki zizokonakala ngesikhathi sesigaba sokupholisa. Ngaphansi kwalesi simo, indlela yokubumba yokwakheka iyashintshwa ukuze ihambise ukuphambuka kwejometri yengxenye yepulasitiki. Isibonelo, yize udonga lwengxenye yepulasitiki lugcinwa luqondile, isikhungo sereferensi siphambukile ngo-10 mm; isisekelo sokubumba singaphakanyiswa ukuze kulungiswe inani le-shrinkage yalesi sinqumo.

7. Inani le-shrinkage kumele libhekwe ekwenziweni kwezikhunta zokwenza ipulasitiki. 1 Umkhiqizo obunjiwe uyancipha. Uma i-shrinkage yepulasitiki ingaziwa kahle, kufanele isampulwe noma ihlolwe isikhunta esakhiwe ngendlela efanayo. Qaphela: Kungatholakala i-shrinkage kuphela ngale ndlela, futhi usayizi owonakele awutholakali. 2 I-shrinkage ebangelwa yimiphumela emibi yaphakathi nendawo, njenge-ceramics, irabicic ye-silicone, njll.
