Kuumbwa uye kushandiswa kweshizha kuumbwa compand

Shep inoumbwa compound inoreva polyester rester resin semuviri mukuru, kuwedzera kurapa mumiriri, filler Iri pepa rinonyanya kunotsanangura muchidimbu kuumbwa uye kusarudzika kwekushandisa kweSMC.

Sheet inoumbwa yakanyorwa's composition

SMC inoumbwa nePolyester Rester Resin, Crosslinking Mumiririri, Inthicator, Filer, Sunungura Agent, Girazi Fiber, uye Polmerization Inhibitor. Pakati pavo, zvikamu zvina zvekutanga zvinonyanya kupa iwo maitiro ezvekushandisa kune zvigadzirwa uye kuwedzera simba. Mapoka mana ekupedzisira ari kunyanya kune zvivakwa zvehuwandu hwekuwedzera, kupesana, kusimbisa, uye kugadzikana kwechimiro chechigadzirwa.

1. Isina kusimbiswa polyester resin uye crosslinking vamiririri ndiwo muviri mukuru weSMC. Asina kusimbiswa polyester inowanzo polycondensed kubva kune isina kusimbiswa dicarboxylic acids (kana anhydrrides), yakagutswa dicarboxylic acids (kana anhydrides), uye polydrides), uye polydrides), uye polydrides), uye polydrides), uye polydrides), uye polydrides), uye polydrides), uye polydrides), uye polydrides), uye polydrides), uye polydrides), uye polydrides), uye polydrides), uye polydrides), uye polydrides), uye polydrides), uye mapepa. Iyo ine zvimwe zvekushandisa uye simba, uye simba remukati rakazara yunifomu. Mumiriri wekuyambuka anonyanya kuve styrene. Pashure pokunge vaviri vacho vari kuyambuka, ndezvekunyora kwepasi rekuporesa kwechigadzirwa, icho chinotamba chinzvimbo chekubatana, kutsigirwa, kutenderwa, uye kudzivirira.

2. Basa rayo rinonyanya kuita kuti resin uye mbiri bondincing monomer yakadai sedryrene copolymerize kuitira kuti smc inogona kusimbiswa uye yakaumbwa muumbi cavity.

3. Iyo filer inogara zvinopfuura chikamu chimwe chete muzvitatu cheepa chinogunun'una uye chinogona kugadzirisa visikoka yeiyo yekuumbwa. Zvinowanzoda kuve nehunhu hwehunhu hwakaderera hwemafuta, yakaderera yemafuta adsorption kukosha, pores mashoma, kukanganisa, uye mutengo wakaderera. Iyo inowanzoshandiswa zvigadzirwa zvefirita zvinonyanya kuwanda caccount3, al (o) 3, zvichingodaro.

4. Manhamba anopa SMC yakakwira-viscosity, isiri-inonamira pfuma. Kugadzirira kwepepa uye bulk kuumbwa kwemakompiso kunoda rwonzi rwakaderera rwevatengi weiyo resin kuti ifambise kusakwana kweiyo girazi fiber uye filler neiyo resin. Uye kumanikidza kuumbwa kunoda wakura viscosity. Naizvozvo, zvinodikanwa kuti uwedzere thickkener isati yabatanidza maitiro ekuumba kushandura viscosity yakaderera yegirazi fiber kusakwana mune yakakwira viscosity isina kunamira.

5. Iyo yekuburitswa Agent inodzivirira iyo pepa kuumbwa yakanyorwa kubva kune yakabatana neiyo simbi yekuumbwa. Iyo yekuburitswa mumiriri inogona kudzivirira iyo isina kugadzikana polyester resin kubva kufambidzana neyekumusoro kwesimbi kuumbwa panguva yepurasitiki maitiro emusanganiswa wemugumo. Kunyanya long-keteni yemafuta macids kana salts inomiririrwa ne zinc stearate. Kunyanya kushandisa kuchaderedza zviri nyore kuita kwechigadzirwa. Iyo general yekushandisa maakaundi e1 ~ 3% yeiyo yakazara chigadzirwa kuti uve nechokwadi chechigadzirwa chechigadzirwa.

6. Magirazi mafuru anogona kusimudzira iyo corrosion kuramba uye insulation zvivakwa zve smc. Sheet inoumbwa compound kazhinji inosarudza yakachekwa girazi fiber matse sekusimbisa zvinyorwa. Kushandisa zvakawandisa kuchaita kuti chigadzirwa chigadzirwa chigadzirwa, uye kushandiswa kweiyo diki dhidhi hakuzove nekuita zviri pachena kusimbisa kwechigadzirwa. Kushandiswa kwakawanda kuri kuita makumi maviri muzana. Nenzira iyi, chigadzirwa chinogona kuzosangana panguva imwe chete yekuwedzera kuumbwa uye kumanikidza kuumba.

7. Inhibitor inowedzera kugadzikana kweSMC uye inowedzera nguva yekuchengetedza. Sezvo iyo yekutanga styrene ichaora zvishoma, ichikonzera polmerization yeiyo resin, kuwedzera huwandu hwakakodzera hwekusununguka kwemahara (Polymerization inhibitor Inhibhitors kazhinji benzoquinesones uye polyvent phenolic makomponi.

Kushandiswa kweshizha kuumbwa zvigadzirwa

SMC ine zvakanakira kushanda kwakanaka kwemagetsi, kwakasimba kurwisa, kureruka, kuri nyore uye kuchinjika mainjiniya maitiro kwakafanana nezvimwe zvinhu zvesimbi. Naizvozvo, inoshandiswa zvakanyanya muminda masere seindasitiri yemotokari, mota dzechitima, kuvaka, magetsi emagetsi, uye kutaurirana (tafura 1).

Pakati pavo, munguva yekutanga, yainyanya kushandiswa muchimiro chekusimbisa mapuranga muminda yekuvaka, zvishandiso zvemagetsi, uye tekinoroji, uye tekinoroji yakura. Yakanga ichishandiswa mumotokari indasitiri yekutsiva chikamu chesimbi uye aluminium alloy zvigadzirwa zvemuviri kuti uderedze uremu hwemota.

Pasi pemashure emagetsi ekuchengetedza simba uye kusimudzira kuderedzwa uye kusimudzira kwemotokari itsva idzva, iyo tekinoroji yezvigadzirwa zvemotokari zvinoramba zvichikura kusvika kune yakareruka uye yakakwirira mhando. Kusvika ikozvino, kushandiswa kweSMC zvinhu kunogona kuoneka kwese kwese muhupenyu hwezuva nezuva. Zvinoratidzwa mukukurukurirana zvisina maofa, zvinoputika.

Pfupisa

Iyo isina kusimbiswa polyester resin, crosslinking mumiririri, anotanga, uye filler mune iyo sheet inoumbwa companded inoisa chimiro chechigadzirwa uye kuwedzera simba rerudzi. Thickener, osunungurwa mumiririri, girazi fiber, uye polmerization inhibitor inowedzera viscosity, Corrosion kuramba, insulation, uye kugadzikana kwechimiro kune chigadzirwa. Zvigadzirwa zvakadaro zvakaiswa muminda masere makuru kusanganisira iyo mota indasitiri uye mota dzechitima. Pasi pemashure okusimbisa kwesimba kuchengetedza, kudzivirirwa kwezvakatipoteredza, uye kuderera kwenzvimbo, iyo indasitiri yemotokari yakaisa mberi zvakakwirira uye zvakakwirira zvinodiwa zveMCC zvinhu nekuda kwezvisikwa zvavo zvekureva zvinhu. Ndeipi iyo huru kutyaira simba rekusimudzira kweSMC tekinoroji.

Shandisa iyocomposite hydraulic press muchinakudzvanya sheething kuumbwa zvigadzirwa zvezvigadzirwa. Zhengxi inyanzviHydraulic Press Factory muChina, kupa michina yemhando yepamusoro. Bata isu kuti tiwane ruzivo.
