Inqubo yokwakha i-vacuum yaziwa ekuqaleni kwekhulu lama-20, kepha isicelo sayo ekukhiqizeni kwezimboni ibingemva kwawo-1940 kuphela, kodwa yathuthukiswa kuphela ngawo-1960. Eminyakeni engama-20 edlule, ithuthukise enye yezindlela ezibaluleke kakhulu zokucubungula izinto zokupakisha. Ukuthuthukiswa okusheshayo kwalobu buchwepheshe kungenxa yokuqamba okuqhubekayo kwezinqubo zokwakha i-vacuum kanye nemishini, kanye nokuthuthukiswa kwamashidi amasha ngokwakha izakhiwo; Kunqunywa nokuthi ukuthuthukiswa komkhakha wokufaka kanye nezimpawu ze-vacuum zakha ukupakishwa uqobo.
I-Vacuum Yakha ingenye yezindlela ezenziwa kakhulu ezakha iziqukathi zokufaka ipulasitiki. Kungubuchwepheshe obuqalisayo obusebenzisa amashidi we-thermoplastic njengento yokubumba. Emazweni angaphandle, ukwakha i-vacuum kuyinqubo yakudala yokubumba. Ngenxa yokuthuthuka okuqhubekayo kanye nezinguquko, kuye kwahleleka kakhulu futhi kwahlehliswa, futhi akutholi izinto zokungcola, kanti ama-100% wezinto zokwakha eziluhlaza nezinsizayo seziyimikhiqizo. Kwakha ubunjiniyela bohlelo lokukhiqizwa okugcwele.
I-Vacuum Blaislong yehluka kule mibandela elandelayo:
· Ukuqiniseka Ukushisa okudingekayo ukushisa izinto zokubumba esimweni esiphakeme kakhulu
Ukubumba kwakheka okuvame ukusetshenziswa ngokwakha ipulasitiki
· Pholisa umkhiqizo kumazinga okushisa apholile lapho kungaguquki ngosayizi
· Ingxenye idonswe ngemuva kokuthi usayizi uqinile
Ezimweni eziningi, ukuphathwa kwangemva kokuphambanisa kokubumba nakho kuyadingeka, njengokuthi:
· Crimming, Welding, Bonding, Ukubopha Ukushisa, Ukuhlanganisa, I-Metallization, Ukuhlamba, Ukuphrinta
I-Vacuum Blaisteling manje isibe yisikhathi esamukelwa kaningi emkhakheni wokucubungula: "Vacuumforming". Kanye "nokuphothula" kubhekiswa kwezinqubo ezithile ezikhethekile ezisebenzisa ukucubungula ingcindezi yomoya. "I-Thermoforming" yigama elijwayelekile lokubumba okuhlukahlukene kwe-thermoplastic, kufaka phakathi i-vacuum nengcindezi, noma ukubumba oku-hybrid.
Okokuqala, izinzuzo nokubi kokubumba kwepulasitiki ye-vacuum
Ukwahlulela ukuthi ngabe kukhona yini izinqubo zokucubungula nokukhiqiza ziphumelela, ngabe izindleko zemikhiqizo ekhiqizwa yindlela kufanelekile uma ziqhathaniswa nenye indlela yokucubungula; Noma izindleko zemikhiqizo ekhiqizwe yizindlela ezimbili ziyafana, kepha zisebenzisa le ndlela ikhwalithi yemikhiqizo ekhiqizwayo. Kuzinhlelo eziningi, ukubumba komjovo noma ukushaya okukhonkotha okuncintisanayo ngokubukwa kwe-vacuum.
Kepha ngokobuchwepheshe bokupakisha, ubuchwepheshe bokwakha we-vacuum abanazo ezinye izindlela zokucubungula okufanele bancintisane nazo ngaphandle kokuthi zenziwe ngamakhadibhodi. Inzuzo enkulu yokwakhiwa kwe-vacuum ngumnotho wayo wobunjiniyela. Ishidi le-composite, ishidi legwebu, nephepha eliphrintiwe libunjiwe ukuthi lithathe indawo yokushintsha i-vacuum eshintsha umshini ngoshintsho olufanele lokubumba olufanele. Izindatshana ezinodonga oluncanyana zingaba yi-vacuum ezakhiwe kusuka kumashidi aphezulu ancibilikina, ngenkathi ama-pellets anesigqila sodonga esifanayo adinga ama-pellets we-viscosity afanayo adinga ukuncibilika kwe-pellets. Ngenombolo encane yezingxenye zepulasitiki, izindleko ezinhle zokubumba zingenye inzuzo yokwakha i-vacuum, kanye nenani elikhulu lezingxenye, kunenzuzo enkulu ukufezekisa ubukhulu obuncane bodonga kanye nesilinganiso esiphakeme sokuphuma komshini owenza i-vacuum. .
Ingxenye encane kunazo zonke engakhiqizwa ngokwakha i-vacuum yinto yokufaka yethebhulethi noma ibhethri lewashi. Ingakhiqiza futhi imikhiqizo emikhulu kakhulu, njengechibi lengadi elingama-3 kuye kwangama-5 ubude. Ubukhulu bezinto zokubumba bungasukela ku-0,05 kuye ku-15 mm, kanye nezinto ezibonakalayo, ubukhulu bungaba ngu-60 mm. Noma iyiphi i-thermoplastic noma izinto ezifanayo zingaba yi-vacuum yakhiwa.
Izinto ezisetshenziselwa ukwakheka kwe-vacuum ishidi elinobukhulu obungu-0.05 kuye ku-15 mm, futhi la mashidi ama-semikhiqizo aqediwe atholakala ngokusebenzisa ama-pellets noma ama-powders. Ngakho-ke, i-vacuum yakha izinto ezingavuthiwe zengeza izindleko ezengeziwe ngokuqhathaniswa nokubumba komjovo.
Ishidi lidinga ukusikwa ngesikhathi sokwakha i-vacuum, ezokhiqiza isikhafu. Lezi zinkimbinkimbi zidilizwa futhi zihlanganiswa nezinto zoqobo zokwakha ishidi futhi.
Ku-vacuum ekwakheni, indawo eyodwa kuphela yeshidi ethintana ne-vacuum ekwakheni isikhunta, ukuze umhlaba owodwa kuphela uvumelane nejometri ye-vacuum ekwakheni isikhunta, kanye ne-contour yenye indawo yomkhiqizo idonswa umdwebo.
Ensimini yokucubungula kwepulasitiki, ukwakhiwa kwe-vacuum kubhekwa njengendlela yokucubungula ngekhono elikhulu lokuthuthuka. Kubunjiwe futhi kufanelekile kuzo zonke izindawo zokupakishwa kwepulasitiki. I-Vacuum Yakha futhi yindlela yokucubungula edinga ukusebenza kwamakhono nesipiliyoni. Namuhla, ukubumba kwe-vacuum kuguquke kube inqubo etholakalayo neyokuphinda ebonakalayo ngokulingisa inqubo kanye nobuchwepheshe obudingekayo.
Eminyakeni yamuva nje, ukuphinda kwenziwa kabusha kwesikhafu ngesikhathi senqubo yokwenza i-vacuum sekubaluleke kakhulu. Kulezi zinsuku, kusungulwe inqubo lapho isikhafu senziwe kabusha ngokuxuba nezinto zoqobo. Imfucumfucu yemikhiqizo enobumba enobumba, njengezinto zokupakisha, kanye nezingxenye zobunjiniyela, kungenzeka ukuthi ziphinde zisetshenziswe ngaphansi kwezimo eziningi, kepha ezinye zidinga ukuthuthukiswa. Izinto ezitholakalayo ezitholakalayo ikakhulukazi izinto zamakhemikhali nezinto zokwakha amandla. Ukuze siphumelele ukuphinda usebenzise kabusha, kufanele sisebenze kanzima endalweni yemvelo nangokomnotho yokucutshungulwa.
Imikhiqizo ye-Vacuum Blister inezinzuzo zamanani aphansi, ukusebenza kahle kokukhiqizwa okuphezulu, ukukhethwa kwamahhala kwezimo nemibala, izinsimbi zokufakelwa, amathoyizi, izidingo zansuku zonke, iWujinjiaodian, imikhiqizo ye-elekthronikhi, ukudla okufakwayo Izimonyo neminye imikhiqizo yathuthukiswa ekusetshenzisweni kwamabhodi ebhodi, izimoto, izingxenye zezimboni, izinto zokwakha, izigqoko zokuvikela, imishini yokuwasha kanye nemikhiqizo yezolimo kanye nemikhiqizo yezolimo.
Okwesibili, ukubumba kwepulasitiki ye-vacuum kunemikhawulo yayo
· Ukwenziwa kwepulasitiki ye-vacuum kungakhiqiza kuphela imikhiqizo ye-Half-shell ngesakhiwo esilula, futhi ubukhulu bemikhiqizo kufanele bube umfaniswano obukhulu (ngokuvamile i-chamfer mncane), kanye nemikhiqizo yepulasitiki enobukhulu obuhle bodonga abakwazi ukuthola.
Ukujula kwemikhiqizo yokwakha i-vacuum kukhawulelwe. Ngokuvamile, ukujula kwesilinganiso se-desimane (h / d) esitsheni akwedlule muntu.
Ukunemba okwenziwe kwalezi zingxenye kumpofu, futhi iphutha elihlobene ngokuvamile lingenhla kwe-1%. Akunzima nje kuphela ukuthola ukuvumelana noma usayizi wezingxenye ezahlukahlukene ngokukha kwe-vacuum, kanye nokufana kodonga lwengxenye ngayinye yengxenye efanayo kunzima ukuqinisekisa. Ngaphezu kwalokho, eminye imininingwane yesibumba ngesikhathi senqubo yokwenza i-vacuum inzima. Akuboniswa ngokuphelele kumkhiqizo.
