Ipulasitiki enegwebu uhlobo lwempahla ye-polymer eyakhiwe ama-micropores amaningi egesi ahlakazwe kumapulasitiki aqinile. Inezinzuzo zokuvala ukushisa, isisindo esincane, ukumelana nokushaqeka, ukumuncwa komsindo, ukumelana nokugqwala kanye nokumelana nomswakama. Amapulasitiki endabuko anegwebu avamile abhekisela ku-polystyrene (PS), i-polyurethane (PUR), i-phenolic resin (PF), i-polyethylene (PE) ne-polyvinyl chloride (PVC).
Amapulasitiki anegwebu ahlukaniswa abe amagwebu athambile, aqinile kancane futhi aqinile ngokusekelwe ekuguquguqukeni kwawo. Amapulasitiki anegwebu aqinile asetshenziswa njengezinto zokufakwa komsindo kanye nezinto zokufakwa ezishisayo zamapayipi neziqukathi, izinto zokupakisha ezimunca ukushaqeka nezinto ezintantayo. Amapulasitiki anegwebu elithambile asetshenziswa njengesikhumba sokwenziwa esiyigwebu nezinto zomcamelo.
Iyini i-Insulation Foam?
Igwebu le-insulation liwuhlobo lwepulasitiki eqinile yegwebu. I-polymer eyakha igwebu le-insulating isesimweni se-crystalline noma se-amorphous, futhi izinga lokushisa layo lokushintsha kwengilazi liphakeme kunezinga lokushisa elivamile. Ngakho-ke, i-foam ye-insulation inokuthungwa okunzima ekushiseni okujwayelekile. Ngakho-ke, ungayisika kanjani ibe yizimo ezahlukene ngomshini we-laser, nokuthi ungaqopha kanjani amaphethini ahlukene ebusweni bayo.
Okokuqala, sidinga ukuqonda ukuthi uyini umshini wokuqopha we-laser foam nokusika nokuthi usebenza kanjani?
Uyini Umshini Wokusika I-Laser Foam Engraver?
Umshini wokudweba we-laser foam kanye nokusika iyisisetshenziswa esizenzakalelayo esisebenzisa ukushisa okuphezulu kwe-laser beam ekhishwa kushubhu ye-laser ukuze idluliselwe ebusweni be-foam. Inokusikwa okunembile, isivinini esisheshayo, ukusebenza okulula, ukucutshungulwa komuntu siqu kanye nokunemba, ikhanda le-laser eligijima isibonisi sekulingisa se-trajectory, imisebenzi eminingi yokwenza kahle indlela, kanye nesistimu yokuhlela ngokuzenzakalelayo ukuze kuqinisekiswe ukonga okuphezulu kwempahla nokonga izindleko, kulungele ikakhulukazi ukuqoshwa kwegwebu le-insulation kanye nokusika.
Usebenza Kanjani Umshini Wokuqopha we-Laser Foam Cutter?
Ngokuhamba kwesikhundla esihlobene se-laser beam kanye negwebu, igwebu ekugcineni liqoshwe ngephethini noma kwakhiwa i-slit, ukuze kuzuzwe inhloso yokudweba nokusika igwebu.
Isetshenziselwa ikakhulukazi ukusika izinto ezihlukahlukene ze-polymer ezifana nepulasitiki yobunjiniyela, amaplastiki angamagwebu, amaplastiki ajwayelekile. Amandla alolu hlobo lomshini ngokuvamile awaphezulu kakhulu, futhi inani le-calorific aliphezulu, ngakho-ke ububanzi bokusika abukhulu kakhulu.
Umshini We-Laser Usika Futhi Uqophe Kanjani Igwebu Lokufaka I-Pink?
The umshini we-laser iyithuluzi elivumelana nezimo kakhulu elivumela yonke into kusuka ekwakhiweni kwe-prototyping kuya ekukhiqizeni ngobuningi. Ungaqala kusukela kuhlelo lokuklama, olubaluleke kakhulu ekwenzeni i-prototyping ngokushesha. Uma kuqhathaniswa nezinqubo eziyinkimbinkimbi zokusika i-jet yamanzi, imishini ye-laser ishesha kakhulu, iguquguquka futhi isebenza kahle. Ukusika igwebu le-insulation nge-laser kudala imiphetho ehlanzekile ehlanganisiwe, evalekile.
Ukushiya inothi kugwebu lokufakelwa, a 60W Ijeneretha ye-laser ingaphezu kokwanele. Ngokuvamile, i-laser generator engaphezu kuka 80W kuyadingeka ukusika i-foam ye-insulation. I-wattage ethize incike kubukhulu begwebu le-insulation kanye nezidingo zakho. ukusika ukusebenza kahle. Ngokuvamile, amandla aphezulu, igwebu lingasikwa libe likhulu, futhi isivinini sokusika siyashesha.
Ngaphambi kokuqala i- umshini wokuqopha laser, kufanele uhlole ukuthi ukunikezwa kwamandla kujwayelekile yini, ukuthi ithangi lamanzi okupholisa ligcwele amanzi akhishwe yi-deionized, nokuthi ingabe iphampu yamanzi ajikelezayo kanye namapayipi okungena nawokuphuma ajwayelekile. Hlola ukuthi inkinobho yokumisa izimo eziphuthumayo ye-laser ayicindezelwe yini, futhi azikho izinsalela phezulu nangaphakathi komshini. Bheka ukuthi amalensi ahlanzekile yini. Uma kukhona ukungcola, kufanele kuhlanzwe ngaphambi kokusetshenziswa. Hlola ingxenye ewumshini ukuze uqinisekise ukuthi ayikho imfucumfucu etafuleni lokucubungula. Hlola ukuthi iphampu yomoya ka-electromagnetic isebenza ngokujwayelekile yini.
Uma konke kuhamba kahle, ake siqale ukuqopha nokusika igwebu elibomvana ngomshini we-laser.
Isinyathelo 1. Vula iswishi yamandla eyinhloko, bese uvula iswishi yamandla okulawula umshini. Ngemuva kokuthi uhlelo lokuzihlola luqediwe, i-eksisi ngayinye yomshini ibuyela endaweni eyinkomba.
Isinyathelo sesi-2. Vula amandla ekhabhinethi yokulawula, vula iphampu yamanzi ejikelezayo, futhi uqinisekise ukuthi kukhona amanzi agelezayo aphuma endaweni yokuphuma kwamanzi.
Qala i-chiller bese uhlola izinga lokushisa kwamanzi nokucindezela (umfutho wamanzi ovamile ngu-5bar). Ngemuva kwemizuzu engu-3 i-chiller ivuliwe, i-compressor iyaqala, ifeni iyajikeleza, futhi ukupholisa kuyaqala.
Isinyathelo sesi-3. Qala i-air compressor kanye nesomisi somoya. Ngemuva kokuthi i-chiller yehla ekushiseni okumisiwe (kusethwe ku-21 degrees), vula amandla amakhulu we-laser generator.
Isinyathelo 4. Faka ukhiye wamandla we-laser embotsheni yokhiye weswishi, vula ukhiye ngokwewashi ukuze uvule amandla e-laser, bese ulinda ukuthi isistimu ibe evamile (cishe imizuzwana engama-30).
Isinyathelo 5. Khipha ngokuqondile usuka kukhompuyutha uye kusofthiwe ye-laser ngekhebula ledatha, noma ungakhetha ukuthekelisa kumemori ye-USB flash, bese udawuniloda emshinini we-laser.
Isinyathelo sesi-6. Uma igama elithi "KULUNGILE" livela kuphaneli ye-laser, sebenzisa i-voltage ephezulu.
Isinyathelo sesi-7. Qinisekisa uhlobo lwempahla, ukujiya kwempahla kanye nosayizi wempahla ngaphambi kokusika. Beka igwebu le-insulation elizoqoshwa futhi lisikwe endaweni yokusebenza.
Isinyathelo 8. Sebenzisa irula evamile ukuze ulungise i-h8 yekhanda le-laser, futhi ulungise ipuleti ukuze unqenqema luhambisane ne-X-axis kanye ne-Y-axis yethuluzi lomshini ukuvimbela ikhanda le-laser ekusebenzeni ngaphandle kobubanzi bepuleti.
Isinyathelo sesi-9. Hambisa i-axis ye-Z lapho uqala umsebenzi, ulingisa uhlelo oluzokwenziwa, qinisekisa ukuthi ayikho i-alamu yomkhawulo othambile, faka imodi yokuhlela, futhi ulungise amandla, isivinini, uhlobo lwesikhathi sokubhoboza kanye nobukhulu ngokusho kokuqukethwe.
Isinyathelo 10. Ngemuva kokuthi izinto ezingenhla sezijwayelekile, ungashintshela esimweni sokubulawa, futhi ungaqala ukuqopha nokusika igwebu le-insulation.
Lapho umsebenzi usuphelile, vala ngohlelo olulandelayo:
1. Ngemuva kokuthi ukucubungula sekuqediwe, insimbi iyakhala, vula ikhava yendlu, bese ukhipha izinto ezicutshunguliwe.
2. Vula ukhiye ngokuphambene newashi ukuze uvale i-laser, bese uvala iphampu yamanzi ejikelezayo ngemva komzuzu o-1.
3. Hlanza izinsalela zokucubungula emshinini.
4. Cisha ikhabethe lokulawula.
5. Vala isomisi somoya kanye ne-compressor yomoya.
Izinto Zokucatshangelwa
1. Landela ngokuqinile ukulandelana komsebenzi ukuze uvule futhi uvale.
2. Abasebenzi abangenazo iziqu banqatshelwe ukusebenzisa nokulungisa umshini.
3. Ngesikhathi senqubo yokusebenza, kwenqatshelwe ngokuphelele ukungena ebhentshini lokusebenzela ukuze kuqinisekiswe ukuphepha komuntu nomshini. Uma u-opharetha ehlangabezana nesimo esiyingozi, u-opharetha kufanele agxilise ingqondo futhi acindezele inkinobho "yokumisa izimo eziphuthumayo" ngokushesha ngangokunokwenzeka.
4. Ukulungiswa kwendlela ye-optical kanye nekhanda le-laser kwimodi yokulandelela kufanele kwenziwe ngokulandelana okulungile kokusebenza ukuze kuqinisekiswe ukuphepha komuntu nomshini.
6. Njalo lapho uqala umshini, kufanele ubuyele endaweni yokubhekisela, uhlole futhi uhlanze isibuko sokugxila, ulinganise i-coaxiality ye-nozzle ye-beam, uvule igesi elisizayo lokusika, futhi ukucindezela ebhodleleni akufanele kube kukhulu kakhulu (Ngaphansi kwe-1Mpa).
Ngamafuphi, uma kuqhathaniswa nezindlela zendabuko zokuqopha nezindlela zokusika, ukuqoshwa kwe-laser nokusika igwebu le-insulation elipinki liyashesha, lisebenza kahle, linembe kakhulu, futhi ingaphezulu ngeke lonakale. Kungakhathaliseki ukuthi i-hobbyist noma ukukhiqiza ngobuningi bezimboni, lokhu kuyisinqumo esihle.
