Ukukhipha igwebu elilahlekile, okwaziwa nangokuthi ukubunjwa kwesikhunta esiqinile, ukuhlanganisa nokuhlanganisa amamodeli egwebu anosayizi ofanayo nokulingisa abe amaqoqo amamodeli.Ngemuva kokuxubha ngopende ophikisayo nokomisa, zingcwatshwa esihlabathini esomile se-quartz ukuze zifane ne-vibration, futhi zithelwe ngaphansi kwengcindezi engalungile ukwenza iqoqo lemodeli.Imodeli ye-gasification, insimbi ewuketshezi ithatha isikhundla semodeli, iqinisiwe futhi ipholisiwe ukuze yakhe indlela entsha yokulingisa.Yonke inqubo ihamba kanje:

Okokuqala, ukukhetha ubuhlalu be-foam:

Ubuhlalu be-polystyrene resin (EPS) obunwebekayo buvame ukusetshenziselwa ukuphonsa izinsimbi ezingenayo insimbi, insimbi empunga kanye nokusakazwa kwensimbi okuvamile.

2. Ukwenza amamodeli: Kunezimo ezimbili:

1. Yenziwe ngobuhlalu begwebu: igwebu ngaphambili - ukuphulukiswa - ukubumba igwebu - ukupholisa nokukhipha

①I-Pre-foaming: Ngaphambi kokuthi ubuhlalu be-EPS bungezwe esibunjeni, kufanele bufakwe amagwebu ngaphambili ukuze bunwebe ubuhlalu bufike kusayizi othile.Inqubo yokukhipha amagwebu ngaphambili inquma ukuminyana, ukuzinza kwe-dimensional nokunemba kwemodeli futhi ingenye yezixhumanisi ezibalulekile.Kunezindlela ezintathu ezifanele zokuthi ubuhlalu bufakwe ngaphambili: ukufaka ugwebu emanzini ashisayo, ukwenza i-steam prefoaming kanye ne-vacuum prefoaming.Ubuhlalu obufakwe ngaphambili be-vacuum bunezinga eliphezulu lokukhihliza amagwebu, ubuhlalu obomile, futhi busetshenziswa kakhulu.

②Ukuguga: Ubuhlalu be-EPS obufakwe amagwebu ngaphambili bufakwa esiseleni esomile nesinomoya isikhathi esithile.Ukuze ulinganise ingcindezi yangaphandle emangqamuzaneni obuhlalu, yenza ubuhlalu bube nokunwebeka kanye nekhono lokunweba kabusha, futhi ususe amanzi ebusweni bobuhlalu.Isikhathi sokuguga amahora angama-8 kuye kwangama-48.

③Ukubunjwa kwegwebu: Gcwalisa ubuhlalu be-EPS obufakwe amagwebu ngaphambili futhi belashiwe endaweni yesikhunta sensimbi, bese ushisisa ubuhlalu ukuze bunwebe futhi, ugcwalise izikhala phakathi kobuhlalu, bese uhlanganisa ubuhlalu ngomunye nomunye ukuze wenze indawo ebushelelezi, imodeli. .Kumele ipholile ngaphambi kokuba isikhunta sikhishwe, ukuze imodeli ipholile ibe ngaphansi kwezinga lokushisa elithambile, futhi isikhunta singakhululwa ngemva kokuba imodeli iqiniswe futhi ibunjwe.Ngemuva kokukhishwa kwesikhunta, kufanele kube nesikhathi sokuthi imodeli yome futhi izinze ngosayizi.

2. Yenziwe nge-foam plastic sheet: ishidi lepulasitiki le-foam - ukusika ucingo lokumelana - ukubopha - imodeli.Ukuze uthole amamodeli alula, idivayisi yokusika ucingo yokumelana ingasetshenziswa ukusika ishidi lepulasitiki le-foam libe yimodeli edingekayo.Ukuze uthole amamodeli ayinkimbinkimbi, qala usebenzise idivayisi yokusika ucingo ukuze uhlukanise imodeli ibe izingxenye eziningana, bese uyinamathisela ukuze wenze imodeli yonke.

3. Amamodeli ahlanganiswa abe amaqoqo: imodeli yegwebu elizicubungulileyo (noma elithengiwe) kanye nemodeli yesikhuphukeli esithelayo kuhlangene futhi kuhlanganiswe ndawonye ukuze kwakheke iqoqo eliyimodeli.Le nhlanganisela ngezinye izikhathi yenziwa ngaphambi kokugqoka, ngezinye izikhathi ekulungiseleleni ukugqoka.Kwenziwa ngesikhathi sokumodeliswa kwebhokisi langemva kokushumeka.Kuyinqubo esemqoka ekubunjweni kwegwebu elilahlekile (okuqinile).Izinto zokubopha ezisetshenziswayo njengamanje: i-raber latex, i-resin solvent kanye ne-adhesive encibilikayo eshisayo nephepha le-tape.

4. Ukufakwa kwemodeli: Ingaphezulu lemodeli ye-foam eqinile kufanele ihlanganiswe nobukhulu obuthile bopende ukuze kwakhiwe igobolondo elingaphakathi lesikhunta sokuphonsa.Ukuze uthole upende okhethekile wokukhipha igwebu elilahlekile, engeza amanzi bese ugoqa kumxube wopende ukuze uthole i-viscosity efanelekile.Upende onyakaziswayo ufakwa esitsheni, futhi iqembu lemodeli lihlanganiswe nezindlela zokucwilisa, ukuxubha, ukugeza nokufutha.Ngokuvamile, sebenzisa kabili ukuze wenze ukujiya enamathela 0.5 ~ 2mm.Ikhethwa ngokuya ngohlobo lwe-alloy casting, ukwakheka kwesakhiwo nosayizi.I-coating yomile ku-40 ~ 50 ℃.

5. Imodeli yokudlidliza: inqubo ihlanganisa izinyathelo ezilandelayo: ukulungiswa kombhede wesihlabathi - ukubeka imodeli ye-EPS - isihlabathi sokugcwalisa - ukuvala nokubunjwa.

①Ukulungiswa kombhede wesihlabathi: Beka ibhokisi lesihlabathi elinegumbi lokukhipha umoya etafuleni elidlidlizayo bese ulibamba liqine.

②Beka imodeli: Ngemva kokudlidliza, beka imodeli yeqembu le-EPS kuyo ngokuvumelana nezidingo zenqubo, futhi uyilungise ngesihlabathi.

③ Ukugcwaliswa kwesihlabathi: engeza isihlabathi esomile (izindlela ezimbalwa zokwengeza isihlabathi), futhi ngesikhathi esifanayo sebenzisa ukudlidliza (X, Y, Z tinkhombandlela ezintathu), isikhathi ngokuvamile siyimizuzwana engama-30 ~ 60, ukuze isihlabathi sokubumba sigcwale zonke izingxenye. wemodeli, futhi isihlabathi sigcwele isihlabathi.Ukuminyana kwenqwaba kuyanda.

④Ukuvala nokuma: Ingaphezulu lebhokisi lesihlabathi livalwe ngefilimu yepulasitiki, ingaphakathi lebhokisi lesihlabathi liphonswa endaweni engenalutho ngepompo ye-vacuum, futhi izinhlamvu zesihlabathi "zihlanganiswe" ndawonye ngomehluko phakathi kwengcindezi yomoya ingcindezi ekubunjeni, ukuze kugcinwe isikhunta singawi ngesikhathi sokuthulula., okubizwa ngokuthi "i-negative pressure setting, esetshenziswa kakhulu.

6. Ukuthela esikhundleni: Imodeli ivamise ukuthanjiswa cishe ku-80 °C, futhi ibole ku-420~480 °C.Imikhiqizo yokubola inezingxenye ezintathu: igesi, uketshezi kanye nokuqinile.Izinga lokushisa lokubola okushisayo lihlukile, futhi okuqukethwe kokuthathu kuhlukile.Lapho isikhunta esiqinile sithululelwa, ngaphansi kokushisa kwensimbi ewuketshezi, imodeli ye-EPS idlula i-pyrolysis kanye ne-gasification, futhi inani elikhulu legesi likhiqizwa, elikhishwa ngokuqhubekayo ngesihlabathi esimbozayo futhi likhishelwe ngaphandle, lakha umoya othile. ingcindezi esikhunjeni, imodeli kanye negebe lensimbi.Insimbi ngokuqhubekayo ithatha isikhundla semodeli ye-EPS futhi iqhubekela phambili, futhi inqubo yokushintshwa kwensimbi ewuketshezi kanye nemodeli ye-EPS kwenzeka.Umphumela wokugcina wokugudluzwa wukwakheka kokulingisa.

7. Ukupholisa nokuhlanza: Ngemva kokupholisa, kulula kakhulu ukuwisa isihlabathi ekubunjweni okuqinile.Kungenzeka ukutshekisa ibhokisi lesihlabathi ukuze uphakamise ukuphonsa ngaphandle kwebhokisi lesihlabathi noma uphakamise ngokuqondile ukuphonsa ngaphandle kwebhokisi lesihlabathi, futhi isihlabathi sokuphonsa nesomile sihlukaniswa ngokwemvelo.Isihlabathi esomile esihlukanisiwe siyaphathwa futhi siphinde sisetshenziswe.
