Ukwakheka kanye nokusetshenziswa kwe-Sheet yokubumba compacting

I-Sheet yokubumba yokubumba isho i-pollert resen engafakwanga kahle njengomzimba oyinhloko, ungeze i-ejenti yokwelapha, i-ejenti yokukhipha isikhunta, i-fillene, njll. Leli phepha ikakhulukazi lichaza kafushane ukwakheka kanye nokusetshenziswa kokuhlukaniswa kwe-SMC.

Ishidi lokuhlanganisa le-complec compacting

I-SMC yakhiwa nge-polyester resin engafakwanga, i-ejenti yokuwela, umsunguli, i-filler, i-ejenti, i-agem fiber, ne-polymerization inhibitor. Phakathi kwazo, izigaba ezine zokuqala zihlinzeka ngohlaka lwezinto ezibonakalayo zemikhiqizo futhi zikhuphule amandla. Imikhakha emine yokugcina ikakhulukazi yezakhiwo zokuvuleka okwengeziwe, ukumelana nokugqwala, ukufakwa, kanye nokuqina kwesakhiwo komkhiqizo.

1. I-Polyeture Resin ye-polyendurter kanye nama-crosslinking agents angumzimba omkhulu we-SMC. Ama-pollins we-polyeture angenasisekelo ajwayele ukufakwa kuma-polyconden kusuka kuma-dicarboxbylic acid (noma ama-anhydrides), ama-dicarboxylic acid (noma ama-anhydrides), nama-polyols. Inezakhiwo ezithile zemishini namandla, namandla angaphakathi afanayo. Umenzeli we-crosslinking ikakhulukazi uStyrene. Ngemuva kokuthi bobabili baxhumekile, bayizinto ezisemqoka zeplastiki yeplastiki yoMkhiqizo, odlala indima yokuxhuma, ukusekelwa, ukuhambisa ibhalansi, nokuvikelwa.

2 Umsebenzi wayo ikakhulukazi wokwenza i-resin kanye ne-Double Bond ku-monomer exhumanisa nesiphambano njenge-styrene copolymerize ukuze i-SMC ingaqinisekiswa futhi yasungulwa emgodini wokubumba.

I-3. I-filler ihlala ngaphezu kwengxenye eyodwa kwezintathu yeshidi yokubumba futhi ingaguqula i-viscosity yekhompiyutha yokubumba. Ngokuvamile kudinga ukuba nezimpawu zokudonsela phansi okuthile okuphansi, inani eliphansi lamafutha advection, ama-pores ambalwa, ukumelana nokugqwala, nezindleko eziphansi. Izakhi ze-filler ezivame ukusetshenziswa ikakhulukazi yi-caco3, al (oh) 3, njalonjalo.

I-4 Ukulungiswa kweshidi kanye nezinhlanganisela zokubumba ngobuningi kudinga ukubonakala okuphansi kwe-resin ukwenza lula ukukhishwa kwefayibha yengilazi kanye ne-filler nge-resin. Futhi ukubumba kokucindezela kudinga ukubonakala okuphezulu. Ngakho-ke, kuyadingeka ukwengeza umkhulu ngaphambi kwenqubo yokubumba ukuguqula i-viscosity ephansi yokugcwala kwe-Glass fiber ukumiswa okuphezulu okunganamatheli.

5 I-ejenti yokukhishwa ingavimba i-polyester resen engafakwanga ukuthi ingasebenzi ebusweni besibumba sensimbi ngesikhathi senqubo yeplastiki yengxube ye-resin. Kade ama-acid amataku anamafutha amade noma usawoti omelwe yi-zinc stearte. Ukusetshenziswa ngokweqile kuzonciphisa kalula ukusebenza komkhiqizo. Ama-akhawunti wokusebenzisa jikelele angu-1 ~ 3% womkhiqizo ophelele ukuze aqinisekise ikhwalithi yomkhiqizo.

I-6 I-Sheet yokubumba compound ivame ukukhetha ama-fiber fiber aqoshiwe njengezinto eziqinisiwe. Ukusetshenziswa ngokweqile kuzokwenza kalula umkhiqizo ugcwele kakhulu, futhi ukusetshenziswa okuncane kakhulu komthamo ngeke kube nomphumela onamandla wokuqinisa umkhiqizo. Ukusetshenziswa okujwayelekile kungama-20%. Ngale ndlela, umkhiqizo ungahlangabezana ngasikhathi sinye nezinqubo ezimbili zokubumba kokubumba nokubumba kokucindezela.

7. I-Inhibitor yandisa ukuqina kwe-SMC futhi yandisa isikhathi sesitoreji. Njengoba umsunguli styrene azobola kancane, adale i-polymerization ye-resin, engeza inani elifanele le-scavenger yamahhala (i-polymerization inhibitor) idla ijubane lokubola kwe-styrene futhi kwandise isikhathi sayo sokugcina. I-inhibitors imvamisa i-benzoquinones kanye nama-polyvalent phenolic ahlanganisiwe.

Ukusetshenziswa kweshidi lokubumba imikhiqizo eyinkimbinkimbi

I-SMC inezinzuzo zokusebenza kahle kukagesi, ukumelana okuqinile kokugqwala, okungasindi, okulula, okulula futhi okuguquguqukayo kobunjiniyela bokubunjiniyela, njll. Izakhiwo zayo zemishini ziqhathaniswa nezinye izinto zensimbi. Ngakho-ke, isetshenziswa kabanzi emasimini ayisishiyagalombili afana nemboni yezimoto, izimoto zesitimela, ukwakhiwa, izinto zikagesi, kanye nezokuxhumana (ithebula 1).

Phakathi kwazo, ekuqaleni kwawo, kwakusetshenziswa ikakhulukazi ngendlela yokufaka amabhodi afaka amabhodi emikhakheni yokwakha, izinto zikagesi, kanye nezokuxhumana, futhi ubuchwepheshe buvuthiwe. Ngemuva kwalokho yasetshenziswa embonini yezimoto ukuthi ibambe ingxenye yensimbi kanye ne-aluminium alloy izinto zomzimba ukunciphisa isisindo semoto.

Ngaphansi kwesizinda sokonga kwamandla okulondolozwa kwamandla nokuncishiswa kanye nokuthuthukiswa kwezimoto ezintsha zamandla, ubuchwepheshe bemikhiqizo yezimoto iyaqhubeka ukuthuthukisa okungasindi nangekhwalithi ephezulu. Kuze kube manje, ukusetshenziswa kwezinto ze-SMC zingabonakala yonke indawo empilweni yansuku zonke. Kuboniswa ekuxhumaneni nge-wireless, ukufakwa kukagesi kobufakazelwa ngolwazi, izindlu zokungena emhlabathini, izindlu zokugezela, kanye nezitimela zesitimela esiphakeme.

Ithebula 1 Izicelo ezinkulu nezinkambu zokuhlukaniswa kwezinto ze-SMC

Beka kafushane

I-polyester resin engafakwanga, i-ejenti yokuwela, umsunguli, kanye ne-filler ku-sheet yokubumba eshidi inikezela ngohlaka lwezinto ezibonakalayo zomkhiqizo futhi yandise amandla enhlaka. I-Firener, ukhiphe i-ejenti, i-fiber fiber, kanye ne-polymerization inhibitor invisali yokuvuleka, ukumelana nokugqwala, ukufakwa, nokuqina kwesakhiwo kuMkhiqizo. Imikhiqizo enjalo isetshenziswe emasimini amakhulu ayisishiyagalombili kufaka phakathi imboni yezimoto kanye nezimoto zesitimela. Ngaphansi kwesizinda samanje sokongiwa kwamandla, ukuvikelwa kwemvelo, kanye nokusetshenziswa kwamandla okuphansi, imboni yezimoto ibeke phambili izidingo eziphakeme neziphakeme zezinto ezisetshenziswayo ze-SMC ngenxa yezidingo zabo ezingasindi. Yikuphi amandla amakhulu okushayela ukuze kuthuthukiswe ubuchwepheshe be-SMC.

SebenzisaUmshini we-Hydraulic Cinderukucindezela imikhiqizo eshibhile yokubumba. UZhengengxi uchwephesheIfektri yabezindaba ye-Hydraulic eChina, ukuhlinzeka ngemishini esezingeni eliphakeme. Xhumana nathi ukuthola imininingwane.
