Iyiphi impahla efanele yezinkomishi zokumunca?

chaza:

Izinkomishi zokudonsa i-vacuum ziwuhlobo lobuchwepheshe lokugcina okunamathiselwe kwezinto ezimbili nge-vacuum degree ngaphandle kokuhlukana. Kunezicelo zezimboni kanye nezicelo zomphakathi, embonini ngokushintsha isikhala senkomishi yokumunca ukuze kufezeke ukuphatha, inqubo yokufuduka "yokuthatha" kanye "nokubeka", ngokufezekiswa kwemishini ezenzakalelayo. Izakhamuzi ikakhulukazi ukuhlangabezana nezidingo zabantu abalenga izinto zokuphila nganoma yisiphi isikhathi. Ngenxa yokuthi inezici zokuthi "thatha" futhi "beka", isetshenziselwa ukulenga amathawula nezingubo.

Imininingwane

Umgomo wokusebenza wenkomishi yokumunca uncike engxenyeni yomoya wephakeji, osetshenziswayo, amandla enkomishi yokuncela odongeni olufana nendiza, udonga, ingcindezi yengilazi, into ethambile ye-deformation yenkomishi yokumunca iyenzeka, iphakethe lomoya. ukukhishwa, ukwakheka kwe-vacuum. Ngaphakathi nangaphandle kwenkomishi yokumunca ukwenza umehluko womfutho womoya. Ngakho, inkomishi yokumunca inamathele ngokuqinile odongeni.
Izinkomishi zokumunca ezisetshenziswa ebulukhunini bezinto zenjoloba ethambile ngokuvamile zingu-60 ~ 70A, ngokuhambisana nalobu bunzima bento ethambile yerabha ikakhulukazi irabha (ivulcanized), i-silicone, i-TPE kanye ne-PVC ethambile yesine. Ukuqina kwe-TPU ikakhulukazi ku-75A noma ngaphezulu, ngokuvamile akuvamile ukusetshenziswa njengezinto zokusetshenziswa zezinkomishi zokumunca.

Amasu Okweqisa kanye Nezidingo Zokunamathela

I-SILIKE Si-TPVs Overmolding inganamathela kwezinye izinto ngokubumba umjovo. ilungele ukufaka ukubumba kanye noma ukubunjwa kwezinto eziningi. Ukubunjwa kwezinto eziningi kwaziwa ngokuthi i-Multi-shot injection molding, i-Two-Shot Molding, noma i-2K yokubumba.

Ama-Si-TPV anokunamathela okuhle kakhulu ezinhlobonhlobo ze-thermoplastics, kusukela ku-polypropylene ne-polyethylene kuya kuzo zonke izinhlobo zamapulasitiki obunjiniyela.

Lapho ukhetha i-Si-TPV yohlelo lokusebenza lokubumba ngaphezulu, uhlobo lwe-substrate kufanele lucatshangelwe. Akuwona wonke ama-Si-TPV azobophezela kuzo zonke izinhlobo zama-substrates.

Ukuze uthole ulwazi olwengeziwe mayelana nama-Si-TPV athile abumbe ngaphezulu kanye nezinto ezihambisana nawo ze-substrate, sicela uzizwe usithinte.

Isicelo

Izinhlayiya ze-Si-TPV ezithambile ze-TPU ziyi-elastomer esekwe ku-thermoplastic esekelwe ku-thermoplastic (silicone TPV) ehlanganisa ukuguquguquka kwerabha nezinzuzo zokucubungula ze-thermoplastics. ama-substrates, afaka i-PC, i-ABS, i-PC/ABS, i-TPU, i-PA6 kanye nezinto ezifanayo ze-polar.I-Si-TPV ifaneleka ngokukhethekile izinhlelo zokusebenza ezifana nezinkomishi zokudonsa futhi iyisisombululo esithambile, esinobungani bemvelo.

I-PVC: Izinto ze-PVC zibhekwa njengeziphakeme kakhulu ngezinga lempahla yempahla yasendlini, kodwa ngenxa yemiphumela eyingozi yama-plasticizers emzimbeni womuntu, abakhiqizi abaningi baqala kancane kancane ukufuna izinto ezintsha zokuyishintsha. Ngaphezu kwalokho, izinga lokucindezelwa unomphela lokuguquguquka kwe-PVC likhulu kakhulu, ukumelana nokuguga nakho kujwayelekile, ngakho-ke akuyona into efanelekile esetshenziswa ezinkomishini zokumunca.

Irabha: Irabha esilinganisweni sesicelo senkomishi yokumunca iphezulu, kodwa umjikelezo wayo wokucubungula uvame ukuba, izinga eliphansi lokugaywa kabusha, izindleko eziphezulu. Ngaphezu kwalokho, mayelana nokuvikelwa kwemvelo, irabha inephunga elikhulu nezinye izinkinga.

I-Silicone: impahla ye-silicone iyirabha yokwenziwa, eyenziwe ngezinto ezihlukahlukene, inqubo yokukhiqiza eyinkimbinkimbi, amanani wezinto ezingavuthiwe aphezulu, izindleko eziphezulu zokucubungula. I-silicone izinga lokushisa eliphezulu neliphansi, ukumelana nowoyela kungcono, kodwa ukumelana nokuguga nokuguga kuncane kakhulu. Ukuqina kwe-tensile kumpofu kune-TPE.

I-TPE: I-TPE ingeyezinto ze-thermoplastic, kodwa okuqukethwe kwezinsini kuphezulu, kuyasebenziseka kabusha. Ukusebenza okuphezulu kokucubungula, akukho vulcanization, kungenziwa kabusha, kunciphise izindleko. Kodwa i-TPE evamile ifaneleka kakhulu ekukhiqizeni ezinye izinkomishi ezincane zokudonsa isisindo ezinesisindo, uma izimo zokusetshenziswa kwezidingo zenkomishi yokudonsa isisindo ziphezulu kakhulu, i-TPE ayikwazi ukuhlangabezana nezidingo.

Into entsha ye-elastomer ifaneleka kakhulu izinkomishi zokumunca - izinhlayiya ezithambile ze-TPU eziguquliwe Ziqinile futhi zihlala isikhathi eside: Izinto ezithambile ze-TPU eziguquliwe zinamandla amahle nokumelana nemihuzuko, futhi zingamelana namandla amakhulu okudonsa nokudabuka. Lokhu kwenza izinkomishi zokumunca ukuthi zisebenze isikhathi eside futhi zibe nempilo ende. I-Anti-Aging: Impahla ye-TPU eguquliwe ethambile inokuzwakala okushelelayo okuhlala isikhathi eside, ukusetshenziswa kwesikhathi eside kokunamathela okungancibiliki, akukho mafutha okulwa nokuguga, akukho ukwelashwa ngemuva, ukwenza ubuchwepheshe bokucubungula kube lula, ukonga izindleko. Ukuguquguquka nokunwebeka: Impahla ye-TPU eguquliwe ethambile inokunwebeka okuphezulu nokuguquguquka, ingakwazi ukuzivumelanisa nezimo nezindawo ezihlukene ze-workpiece. Ingakwazi ukulingana kangcono indawo yokusebenza futhi inikeze umphumela ongcono wokuvala nokukhangisa, ngaleyo ndlela ikhulise ukuqina nokuthembeka kwenkomishi yokumunca.
Ngaphezu kwalokho, umkhiqizo unikeza izakhiwo zokucubungula ezifana nalezo zezinto ze-TPE zendabuko, kanye nezakhiwo ezinhle kakhulu zemvelo zobunjiniyela kanye nokucindezelwa okwamukelekayo okusethwe ekamelweni namazinga okushisa aphakeme. Ama-elastomer e-Si-TPV ngokuvamile awadingi ukucutshungulwa kwesibili, okuholela ezikhathini zomjikelezo omfushane kanye nezindleko zokukhiqiza eziphansi. Le nto ye-elastomeric ihlinzeka ngokuthungwa okungcono kwerabha ye-silicone emikhiqizweni eqediwe egqitshiwe.
