Ibigize hamwe nogushira mubikorwa impapuro zishushanyije

Urupapuro rwerekana impapuro bivuga polyester idahagije nkumubiri wingenzi, wongeyeho imiti ikiza, umukozi wo kurekura ibicuruzwa, uwuzuza, imiti igabanya ubukana, umubyimba, nibindi.Uru rupapuro rusobanura muri make imiterere nogushyira mubikorwa bya SMC.

Urupapuro rwerekana impapuro

SMC igizwe na polyester idahagije, resin ihuza, uwatangije, yuzuza, umubyimba, umurekura, fibre y ibirahure, hamwe na inhibitor ya polymerisation.Muri byo, ibyiciro bine byambere bitanga ahanini ibikoresho bifatika kubicuruzwa no kongera imbaraga.Ibyiciro bine byanyuma bigizwe ahanini nuburyo bwo kwiyongera kwijimye, kurwanya ruswa, kwikingira, hamwe nuburyo buhamye bwibicuruzwa.

1. Ibikoresho bya polyester bidahagije hamwe nibikoresho bihuza umubiri nyamukuru wa SMC.Ibisigarira bya polyester bidahagije mubisanzwe ni polycondensed biva kuri acide ya dicarboxylic idahagije (cyangwa anhydride), acide dicarboxylic acide (cyangwa anhydride), na polyoli.Ifite imiterere yubukorikori n'imbaraga, kandi imbaraga zimbere ni zimwe.Umukozi uhuza cyane ni styrene.Nyuma yuko byombi bihujwe, nibikoresho byingenzi byo gukiza plastike yibicuruzwa, bigira uruhare rwo guhuza, gushyigikira, kuringaniza imiyoboro, no kurinda.

2. Uwatangije atera resin na crosslinker gukira no gukora murwego rwa resin paste.Igikorwa cyayo ni ugukora cyane cyane ibisigarira hamwe nububiko bubiri muri monomer-ihuza monomer nka styrene copolymerize kugirango SMC ibashe gukomera no gushingwa mumyanya yububiko.

3. Uzuza afite igice kirenze kimwe cya gatatu cyurupapuro rwerekana impapuro kandi arashobora guhindura ububobere bwikibumbano.Mubisanzwe ikeneye kugira ibiranga uburemere buke bwihariye, amavuta ya adsorption make, imyenge mike, kurwanya ruswa, nigiciro gito.Ibikunze gukoreshwa byuzuza cyane cyane CaCO3, Al (OH) 3, nibindi.

4. Inkoko ziha SMC umutungo-mwinshi, udafatanye.Gutegura impapuro hamwe nububiko bwinshi busaba ubukonje buke bwa resin kugirango byorohereze kwinjiza fibre yikirahure hamwe nuwuzuza resin.Kandi gushushanya compression bisaba ubwiza buhanitse.Niyo mpamvu, birakenewe kongeramo umubyimba mbere yuburyo bwo kubumba kugirango uhindure ubukonje buke bwikirahure cya fibre yinjizwamo ububobere buke budafatanye.

5. Umukozi wo kurekura abuza urupapuro rwabumbabumbwe kugirana isano nubuso bwicyuma.Umukozi wo kurekura arashobora gukumira polyester idahagije kugirango idakorana nubuso bwicyuma mugihe cya plastiki yimvange ya resin.Ahanini urunigi rurerure rwa acide cyangwa umunyu ugereranwa na zinc stearate.Gukoresha cyane bizagabanya byoroshye imikorere yibicuruzwa.Imikoreshereze rusange ihwanye na 1 ~ 3% byibicuruzwa byose kugirango hamenyekane ubuziranenge bwibicuruzwa.

6. Fibre fibre irashobora kongera imbaraga zo kurwanya ruswa hamwe na insulation ya SMC.Urupapuro rwerekana impapuro mubisanzwe uhitamo ibirahuri bya fibre byaciwe nkibikoresho byongera imbaraga.Gukoresha cyane bizatuma byoroshye ibicuruzwa bihindagurika, kandi gukoresha ikinini gito cyane ntabwo bizagira ingaruka zigaragara kubicuruzwa.Imikoreshereze rusange ni hafi 20%.Muri ubu buryo, ibicuruzwa birashobora icyarimwe guhura nuburyo bubiri bwo gukuramo ibicuruzwa no guhonyora.

7. Inhibitor yongera ituze rya SMC kandi ikongerera igihe cyo kubika.Kubera ko intangiriro ya styrene izangirika buhoro, bigatera polymerisiyasi ya resin, ukongeramo urugero rukwiye rwa radical scavenger yubusa (polymerisation inhibitor) irashobora kugabanya umuvuduko wo kwangirika kwa styrene kandi ikongerera igihe cyo kubika.Inhibitor ni benzoquinone hamwe na polyvalent fenolike.

Gushyira mu bikorwa urupapuro rwerekana ibicuruzwa

SMC ifite ibyiza byo gukora amashanyarazi meza cyane, irwanya ruswa ikomeye, yoroheje, igishushanyo mbonera cyoroshye, cyoroshye, nibindi.Kubwibyo, ikoreshwa cyane mubice umunani nk'inganda zitwara ibinyabiziga, ibinyabiziga bya gari ya moshi, ubwubatsi, ibikoresho by'amashanyarazi, n'itumanaho (Imbonerahamwe 1).

Muri byo, mu ntangiriro, yakoreshwaga cyane cyane mu buryo bwo kubika imbaho ​​mu bijyanye n'ubwubatsi, ibikoresho by'amashanyarazi, n'itumanaho, kandi ikoranabuhanga rirakuze.Nyuma yaje gukoreshwa mu nganda z’imodoka kugirango isimbuze igice cyibyuma na aluminiyumu yumubiri wumubiri kugirango igabanye uburemere bwimodoka.

Mu rwego rwo kugabanya ingufu zo kuzigama no kugabanya ibyuka bihumanya no guteza imbere ibinyabiziga bishya by’ingufu, ikoranabuhanga ry’ibicuruzwa bitwara ibinyabiziga rikomeje gutera imbere ryoroheje kandi ryiza.Kugeza ubu, ikoreshwa ryibikoresho bya SMC rirashobora kugaragara ahantu hose mubuzima bwa buri munsi.Bigaragarira mu itumanaho ridafite insinga, mu mashanyarazi adashobora guturika, ibikoresho byo kubika ubutaka, ubwiherero, hamwe na gari ya moshi yihuta.

Imbonerahamwe 1 Porogaramu umunani ningenzi zo kugabana ibikoresho bya SMC

Vuga muri make

Poliester idahagije, resin ihuza, uwatangije, hamwe nuwuzuza impapuro zuzuza impapuro zitanga ibikoresho bifatika kubicuruzwa no kongera imbaraga zubaka.Thickener, kurekura ibintu, fibre yibirahure, hamwe na polymerisiyasi inhibitor yongeramo ubwiza, kurwanya ruswa, kwikingira, hamwe nuburyo buhamye mubicuruzwa.Ibicuruzwa nkibi byakoreshejwe mubice umunani byingenzi birimo inganda zimodoka nibinyabiziga bya gari ya moshi.Muri iki gihe cyerekeranye no kubungabunga ingufu, kurengera ibidukikije, no gukoresha ingufu nke, inganda z’imodoka zashyize ahagaragara ibisabwa byinshi kandi byinshi ku bikoresho bya SMC bitewe n’ibisabwa byoroheje.Nizo mbaraga nyamukuru ziterambere ryiterambere rya tekinoroji ya SMC.

Koresha iimashini ikora hydraulic imashinigukanda impapuro zibumba ibicuruzwa.Zhengxi ni umunyamwugauruganda rukora hydraulic mu Bushinwa, gutanga imashini nziza.Twandikire kugirango ubone ibisobanuro birambuye.
