Yikuphi okufanele ukwenze ezinkomishini zokumunca?

chaza:

Izinkomishi zokumunca i-vacuum ziwuhlobo lobuchwepheshe bokugcina ukunamathela kwezinto ezimbili ngezinga le-vacuum ngaphandle kokuhlukaniswa. Kunezinhlelo zokusebenza zezimboni kanye nezinhlelo zokusebenza zomphakathi, embonini ngokushintsha i-vacuum yendebe yokumunca ukuze kufezwe ukuphathwa, inqubo yokufuduka "yokuthatha" kanye "nokubeka", kanye nokufezwa komshini ozenzakalelayo. I-Civil ikakhulukazi ukuhlangabezana nezidingo zabantu abalenga izinto zokuphila nganoma yisiphi isikhathi. Ngenxa yokuthi inezici "zokuthatha" kanye "nokubeka", isetshenziselwa ukulengisa amathawula nezingubo.

Imininingwane

Umgomo wokusebenza wendebe yokumunca uncike engxenyeni egobile yomoya wephakheji, lapho isetshenziswa, amandla endebe yokumunca odongeni olufana nendiza, udonga, ingcindezi yengilazi, izinto ezithambile zokuguqulwa kwendebe yokumunca kwenzeka, iphakheji yomoya ikhishwa, ukwakheka kwe-vacuum. Ngaphakathi nangaphandle kwendebe yokumunca kwakheka umehluko womfutho womoya. Ngakho-ke, indebe yokumunca inamathele ngokuqinile odongeni.
Izinkomishi zokumunca ezisetshenziswa ezintweni zerabha ezithambile ngokuvamile zingama-60 ~ 70A, ngokuhambisana nalokhu kuqina kwezinto zerabha ezithambile ikakhulukazi irabha (evulcanized), i-silicone, i-TPE kanye ne-PVC ethambile ezine. Ubulukhuni be-TPU buvame ukuba ku-75A noma ngaphezulu, ngokuvamile abusetshenziswa kakhulu njengezinto zokusetshenziswa zezinkomishi zokumunca.

Izinzuzo Eziyinhloko

Amasu Okubumba Okungaphezulu kanye Nezidingo Zokunamathela

I-SILIKE Si-TPVs Overmolding inganamathela kwezinye izinto ngokusebenzisa i-injection molding. Ifanelekela i-insert molding noma i-multiple material molding. I-Multi-material molding yaziwa nangokuthi i-Multi-shot injection molding, i-Two-Shot Molding, noma i-2K molding.

Ama-Si-TPV anamathela kahle kakhulu kuma-thermoplastic ahlukahlukene, kusukela ku-polypropylene kanye ne-polyethylene kuya kuzo zonke izinhlobo zamapulasitiki obunjiniyela.

Uma ukhetha i-Si-TPV yokusetshenziswa kokubumba ngokweqile, uhlobo lwe-substrate kufanele lucatshangelwe. Akuwona wonke ama-Si-TPV azonamathela kuzo zonke izinhlobo ze-substrate.

Ukuze uthole ulwazi olwengeziwe mayelana nama-Si-TPV athile asebenzisa i-overmolding kanye nezinto zawo ezihambisanayo ze-substrate, sicela uxhumane nathi.

Isicelo

Izinhlayiya ze-TPU ezithambile ze-Si-TPV ziyi-elastomer entsha esekelwe ku-thermoplastic thermoplastic (i-silicone TPV) ehlanganisa ukuguquguquka kwerabha nezinzuzo zokucubungula ze-thermoplastics. I-SiTPV ayinaphunga eliningi, ayina-plasticizer, futhi kulula ukuyibopha ezinhlotsheni eziningi ze-substrates, kufaka phakathi i-PC, i-ABS, i-PC/ABS, i-TPU, i-PA6 nezinye izinto ezifanayo ze-polar. I-Si-TPV ifaneleka kakhulu ezinhlelweni ezifana nezinkomishi zokumunca futhi iyisisombululo esithambile kakhulu nesinobungani nemvelo.

I-PVC: Izinto ze-PVC zibhekwa njengeziphezulu kakhulu ngesilinganiso sezinto zasekhaya, kodwa ngenxa yemiphumela eyingozi yama-plasticizer emzimbeni womuntu, abakhiqizi abaningi baqala kancane kancane ukufuna izinto ezintsha ukuze bazithathele indawo. Ngaphezu kwalokho, izinga lokuguquguquka okungapheli kwe-PVC likhulu kakhulu, ukumelana nokuguga nakho kuyinto evamile, ngakho akuyona into efanelekile esetshenziswa ezinkomishini zokumunca.

Irabha: izinga lokusetshenziswa kwerabha enkomishini yokumunca liphezulu, kodwa umjikelezo wayo wokucubungula uvame ukuba, izinga eliphansi lokuvuselela, izindleko eziphezulu. Ngaphezu kwalokho, maqondana nokuvikelwa kwemvelo, irabha inephunga elikhulu nezinye izinkinga.

I-Silicone: Izinto ze-silicone ziyirabha yokwenziwa, zenziwe ngezinto ezahlukahlukene, inqubo yokukhiqiza eyinkimbinkimbi, amanani ezinto zokusetshenziswa aphezulu, izindleko zokucubungula ziphakeme. Izinga lokushisa eliphezulu neliphansi le-silicone, ukumelana nowoyela kungcono, kodwa ukumelana kwayo nokuguguleka nokuguga kuphansi kakhulu. Ukuqina kokuqina kuphansi kune-TPE.

I-TPE: I-TPE ingeyokwenziwa kwezinto ze-thermoplastic, kodwa okuqukethwe yi-gum kuphezulu, kungaphinde kusetshenziswe. Ukusebenza kahle kokucubungula, akukho ukuxuba, kungaphinde kusetshenziswe, kunciphisa izindleko. Kodwa i-TPE ejwayelekile ifaneleka kakhulu ekukhiqizweni kwezinkomishi ezincane zokumunca ezithwala isisindo, uma izimo zokusebenzisa izimfuneko zenkomishi yokumunca ziphezulu kakhulu, i-TPE ayikwazi ukuhlangabezana nezidingo.

Izinto ezintsha ze-elastomer zifaneleka kakhulu ezinkomishini zokumunca - izinhlayiya ze-TPU ezithambile eziguquliwe Iqinile futhi ihlala isikhathi eside: Izinto ze-TPU ezithambile eziguquliwe zinamandla amahle nokumelana nokuhuzuka, futhi zingamelana namandla amakhulu okudonswa nokuklebhuka. Lokhu kwenza izinkomishi zokumunca ziqine kakhulu uma zisetshenziswa futhi zihlala isikhathi eside. Ilwa nokuguga: Izinto ze-TPU ezithambile eziguquliwe zinomuzwa obushelelezi ozinzile ohlala isikhathi eside, ukusetshenziswa kwesikhathi eside kokunamathela okungancibiliki, akukho uwoyela ovimbela ukuguga, akukho ukwelashwa ngemuva, kwenza kube lula ubuchwepheshe bokucubungula, ukonga izindleko. Ukuguquguquka nokunwebeka: Izinto ze-TPU ezithambile eziguquliwe zinokunwebeka okuphezulu nokuguquguquka, zingazivumelanisa nezimo ezahlukene kanye nezindawo zomsebenzi. Zingalingana kangcono nobuso bomsebenzi futhi zinikeze umphumela wokuvala nokumunca okungcono, ngaleyo ndlela zandise ukuzinza nokuthembeka kwendebe yokumunca.
Ngaphezu kwalokho, umkhiqizo unikeza izakhiwo zokucubungula ezifana nezezinto ze-TPE zendabuko, kanye nezakhiwo zomzimba ezinhle kakhulu zobunjiniyela kanye nesethi yokucindezela eyamukelekayo ekamelweni kanye namazinga okushisa aphezulu. Ama-elastomer e-Si-TPV ngokuvamile awadingi ukucutshungulwa kwesibili, okuholela ezikhathini zomjikelezo ezimfushane kanye nezindleko zokukhiqiza eziphansi. Le nto ye-elastomeric inikeza ukuthungwa okungcono kwerabha ye-silicone emikhiqizweni eqediwe ehlanganisiwe.
