Umugqa we-Weld uyisici esibalulekile esithinta ikhwalithi yezingxenye zepulasitiki.Ngokwesibonelo, embonini yezimoto, Ngokwesibonelo, embonini yezimoto,obhampa bezimoto, Qeda ukufaka, njll, izingxenye zepulasitiki ezingafanelekile ziholela ngokuqondile ekwehleni kwekhwalithi yemoto futhi zibeke engozini ukuphepha kwempilo yabantu.Ngakho-ke, kubaluleke kakhulu okusebenzayo ukufunda inqubo yokubunjwa kanye nezici ezithonya imigqa ye-weld futhi uthole izindlela zokuqeda imigqa yokushisela.
Kunezinhlobo ezimbili eziyisisekelo zemigqa yokushisela ezingxenyeni ezibunjiwe ngomjovo: eyodwa iwumugqa we-weld obandayo;Enye i-hot-melt weld mark.
Izici ezithonya zomugqa we-weld kanye nezinyathelo zokuthuthukisa nokuqedwa
1. Ithonya lamapharamitha wenqubo yokufaka umjovo kulayini we-weld
a.Umthelela wezinga lokushisa
Ukwandisa izinga lokushisa kungasheshisa inqubo yokuphumula ye-polymer futhi kunciphise isikhathi sokubanjwa kwe-molecular chain entanglement, esiza kakhulu ekuhlanganisweni okugcwele, ukusabalalisa kanye nokugoqa kwama-molecule ekugcineni kwento, ukuze kuthuthukiswe amandla indawo ye-weld line.Izinga lokushisa elincibilikayo linethonya elikhulu emandleni e-weld lineIzingxenye zepulasitiki ze-ABS.
b.Umthelela wengcindezi yomjovo nokubamba ingcindezi
Ukucindezela komjovo kuyisici esibalulekile ekugcwaliseni ukuncibilika kwepulasitiki nokubunjwa.Indima yayo ukunqoba ukumelana nokuncibilika kwepulasitiki okugeleza emgqonyeni, umlomo wombhobho, i-gating system kanye nomgodi, ukunikeza isivinini esanele sokugcwalisa ekuncibilikeni kwepulasitiki, futhi kuhlanganiswe ukuncibilika ukuze kuqinisekiswe ikhwalithi yemikhiqizo ebunjiwe yomjovo.
c.Umthelela wejubane lomjovo kanye nesikhathi somjovo
Ukwandisa ijubane lomjovo kanye nokunciphisa isikhathi somjovo kuzonciphisa isikhathi sokugeleza ngaphambi kokuba i-melt front ihlangane, ukunciphisa ukulahlekelwa ukushisa, ukuqinisa isizukulwane sokushisa kwe-shear, ukunciphisa i-viscosity encibilikayo futhi kwandise uketshezi, ukuze kuthuthukiswe amandla omugqa we-weld. .
2. Ithonya le-die design kulayini we-weld
a.Idizayini yesistimu yokugenca
Lapho inani lamasango liyanda, amamaki e-weld azokhiqizwa.Uma ukuncibilika phambi kokugeleza kwezinto ezivela esangweni ngalinye kungeke kuhlanganiswe kahle, izimpawu ze-weld zizoba nzima futhi izinga lezingxenye zepulasitiki lizothinteka kakhulu.
b.Idizayini yesistimu ye-exhaust kanye nokushaja okubandayo kahle
Igesi esele ekhiqizwe ngenxa yokukhishwa okungalungile icindezelwa emgodini wesikhunta ngesikhathi senqubo yokujova, okungeke kushise imikhiqizo kuphela, kodwa futhi kuholele ekubukeni kwezimpawu zokuhlanganisa.
c.Ukuklama uhlelo lokulawula izinga lokushisa
Ukwehla kwezinga lokushisa kwesikhunta, kulapho kungathandeki khona ukuhlangana okugcwele kokuncibilika.
d.Idizayini ye-surface roughness of cavity and core
Ubulukhuni obungaphezulu bomgodi kanye nomgogodla kuzophinde kuthinte isivinini sokugeleza kokugcwalisa kokuncibilika kwepulasitiki.
e.Ukwenziwa ngcono kwesakhiwo sokufa kwezinye izici
Imodeli yokusetshenziswa ihlobene nesakhiwo sesikhunta esingasusa uphawu lokuhlangana lomkhiqizo obunjwe ngomjovo onezimbotshana.Indlela eqondile ukuthi lapho umkhiqizo usanda kujovwa futhi ugcwaliswe emgodini wesikhunta, into ethambile encibilika emgodini wesikhunta isikwa ngokusebenzisa i-core insert ukuze kutholwe imbobo yomkhiqizo.
3. Ithonya lokulandelana kwe-valve inaliti yesango lobuchwepheshe kulayini we-weld
Enqubweni yokukhiqiza imikhiqizo eminingi ezenzakalelayo, cishe zonke izingxenye ezinkulu zokubumba umjovo zisebenzisa uhlelo lomgijimi oshisayo.Kulolu hlobo lwezingxenye zepulasitiki, ukondla i-multi gate glue kungaqinisekisa ukugcwaliswa okuphelele komgodi futhi kuthuthukise ukusebenza kahle kokugcwalisa, kodwa nakanjani kuzokhiqiza ukugeleza kwezinto zamagatsha, okuholela ekuveleni kwemigqa ye-weld.Ngokuvula inaliti ye-valve yesango ngokulandelana, ukugeleza kokuncibilika kungahlanganiswa kuzo zombili iziphetho zesikhala ngokushintshana, ukuze kuxazululwe inkinga yophawu lwe-weld.
4. Ezinye izindlela zokuthuthukisa amandla e-weld line
a.Indlela yokugcwalisa isikhunta esiphusha kabili
b.Ukudlidliza okusizwa ngomjovo wokubumba
