Imikhiqizo
110 Icala
Isici soMkhiqizo
Ukukhishwa kwegwebu elilahlekile (okubuye kwaziwe ngokuthi ukubunjwa kwesikhunta sangempela) kwenziwa ngepulasitiki eyigwebu (EPS, STMMA noma EPMMA) impahla ye-polymer ibe isikhunta sangempela esinesakhiwo nosayizi ofanayo ncamashi nezingxenye okufanele zikhiqizwe futhi ziphonswe, futhi i-dip-coated. nge-refractory coating (eqinisiwe) , ebushelelezi futhi ephefumulayo) futhi yomisiwe, ingcwatshwa esihlabathini esomile se-quartz futhi ingaphansi kwemodeli yokudlidliza ye-3-dimensional. Insimbi encibilikisiwe ithululelwa ebhokisini lesihlabathi elibunjwa ngaphansi kwengcindezi engalungile, ukuze imodeli yezinto ze-polymer ifudumale futhi iqhume, bese ikhishwa. Indlela entsha yokulingisa esebenzisa insimbi ewuketshezi ukuze imiselele inqubo yesikhathi esisodwa yokubunjwa kwesikhunta eyakhiwe ngemva kokupholisa nokuqiniswa ukuze kukhiqizwe ukulingwa. Ukukhipha igwebu elilahlekile kunezici ezilandelayo: 1. Ukusakaza kungokwekhwalithi enhle nezindleko eziphansi; 2. Izinto ezisetshenziswayo azinqunyelwe futhi zifanele wonke amasayizi; 3. Ukunemba okuphezulu, indawo ebushelelezi, ukuhlanzwa okuncane, nomshini omncane; 4. Ukukhubazeka kwangaphakathi kuyancipha kakhulu futhi isakhiwo sokubunjwa siyathuthukiswa. Kuminyene; 5. Ingakwazi ukukhiqiza izinto ezinkulu nezinkulu; 6. Ilungele ukukhiqizwa kwenqwaba yama-castings afanayo; 7. Ilungele ukusebenza ngesandla kanye nokukhiqizwa komugqa wokuhlanganisa okuzenzakalelayo nokulawula ukusebenza; 8. Isimo sokukhiqiza somugqa wokukhiqiza sihlangabezana nezidingo zemingcele yezobuchwepheshe yokuvikelwa kwemvelo. ; 9. Ingathuthukisa kakhulu indawo yokusebenza kanye nezimo zokukhiqiza zomugqa wokukhiqiza wokuphonsa, inciphise umfutho wabasebenzi, futhi inciphise ukusetshenziswa kwamandla.
Incazelo Yomkhiqizo
Ukukhipha igwebu elilahlekile (kusukela ngo-2018) ukuhlanganisa nokuhlanganisa amamodeli epulasitiki egwebu afanayo ngosayizi nokuma kokulingisa abe amaqoqo amamodeli. Ngemva kokuxubha nge-refractory coating kanye nokomiswa, zigqitshwa esihlabathini esomile se-quartz futhi zidlidlize ukuze zime. Ngaphansi kwezimo ezithile Indlela yokuthela insimbi ewuketshezi, okwenza imodeli ihwamuke futhi ithathe indawo yemodeli, bese iqina futhi iphole ukuze yakhe ukusakaza okufunayo. Izici eziyinhloko zenqubo yendlela yokuphonsa igwebu elahlekile ukukhiqizwa kwesikhunta sepulasitiki se-foam kanye nokusetshenziswa kwezingubo eziphikisayo; ukudlidliza nokuqina kwesihlabathi emva kokubunjwa kwepulasitiki ye-foam kufakwe ebhokisini lesihlabathi; kanye nokugcinwa kwe-vacuum ebhokisini lesihlabathi ngesikhathi sokuthulula. .
Ukukhishwa kwegwebu elilahlekile kunconywa imboni yabasunguli njengokuthi "ubuchwepheshe bokulingisa obusha ekhulwini lama-21" kanye "nephrojekthi eluhlaza ekulingeni". Ukukhishwa kwegwebu elilahlekile kwavivinywa okokuqala ngempumelelo ngu-HF Shroyer ngo-1956. USolwazi A. Witmoser wabambisana ne-Hartman Company futhi waqala ukukusebenzisa ezimbonini ngo-1962. Ezinsukwini zokuqala zokufakwa kwesicelo, ukukhishwa kwegwebu elilahlekile kwakusetshenziselwa ikakhulukazi ukukhiqizwa kwe-single enkulu-. ukukhishwa kwesikali. Kusukela ngawo-1960 kuya ko-1970, indlela yokuphonsa isikhunta kazibuthe yasungulwa. Kusukela ngawo-1980, inqubo yokuqala ebonakala ngokucindezelwa kwe-vacuum negative kanye nokubumba kwesihlabathi esomile sekusungulwe. Isizukulwane sesithathu silahlekelwe ukusakaza kwegwebu.
Ukukhishwa kwegwebu elilahlekile kuwuhlelo olubanzi lwezinqubo eziningi zokuqondiswa kwezigwegwe oluhlanganisa amapulasitiki, amakhemikhali, imishini nokusakazwa. Ihlanganisa ukukhishwa kwegwebu elilahlekile nezinye izinqubo ezintsha zokusakaza ukuze kwakhiwe izindlela ezintsha zenqubo eyinhlanganisela ukuze kuthuthukiswe ikhwalithi yokusakazwa kwegwebu elahlekile. kanye nokusebenza kahle kokukhiqiza kwaba ngcono nakakhulu.
