Ibigize no Gushyira mu bikorwa urupapuro rubi

Urupapuro ruhindura ibigo bivuga resiti idahwitse nkumubiri nyamukuru, yongeraho umukozi wa Agent, filler, FLOLER, FLOLER, FOLLAN, ETC. Uru rupapuro rwinshi rusobanura muri make ibihimbano no gushyira mu bikorwa SMC.

Urupapuro ruhindura ibigo

SMC igizwe na polyester idateganijwe, abakozi basanga, abatavuga, filler, ubumwe, fibre, fibre yikirahure, hamwe na polmerator. Muri bo, ibyiciro bine byambere bitanga ahanini kurwego rwibicuruzwa no kongera imbaraga. Ibyiciro bine byanyuma byanze cyane cyane imiterere yo kwiyongera kwa virusi, kurwanya ruswa, ubushishozi, hamwe nubukungu bwibicuruzwa.

1. Polyester idateganijwe hamwe nabakozi bahura numubiri nyamukuru wa SMC. Polyester idateganijwe muri Polycondeds Polypondeds DICARBEDBOXY YUZUYE (cyangwa anhydrides), aside ya dicarboxy (cyangwa anhydrides), na politile. Ifite imitungo n'imbaraga zimwe, hamwe n'imbaraga zimbere ni imyenda. Umukozi wo kwinurwa ahanini ni Stryrene. Bose bamaze guhuzwa, ni ibikoresho nyamukuru byo gukiza plastike y'ibicuruzwa, bikagira uruhare mu guhuza, gushyigikira, kwandura, no kurinda.

2. Umunyamakuru atera resin na trosliman kugirango bakire kandi ibe murwego rwa resin paste. Igikorwa cyacyo cyane cyane kugirango gishobore gusimbuka hamwe nubucuti bubiri mumurongo wambukiranya nka Styrene copolymeyeri kugirango smcre ya Styrene Copolymeze kugirango ikoreshwe kandi ikorwa muburyo bukabije.

3. Filler ifata ibirenze kimwe cya gatatu cyurupapuro rubumba kandi irashobora guhindura vicoity yo kubumba. Muri rusange hakenewe kugira ibiranga uburemere buke, agaciro ka'amavuta make yo kwamamaza, ubugari buke, kurwanya ruswa, hamwe nigiciro gito. Ibice bikunze gukoreshwa byihuse ni caco3, al (yewe) 3, nibindi.

4. Gutegura ibice no gusubirisha ibice bisaba ubuyoge buke bwa resin kugirango yorohereze inkingi ya fibre yikirahure no kuzuza ibisige. No gutumba kwubumba bisaba ubushishozi bwo hejuru. Kubwibyo, birakenewe kongeramo ubumwe mbere yo kubumba kugirango uhindure vino nkeya yikirahure fibre idahinduka virusi ndende idashidikanywaho.

5. Umukozi urekura ibuza urupapuro rubumba rufite isano hamwe nubutaka bwo hasi. Umukozi urekura arashobora kubuza resiti idateganijwe muburyo bwo gusabana nubutaka bwicyuma mugihe cya plastike kuvanga resike. Ahanini acide acide cyangwa umunyu uhagarariwe na zinc. Gukoresha cyane bizagabanya byoroshye imikorere yibicuruzwa. Konti rusange ikoreshwa kuri 1 ~ 3% yibicuruzwa byose kugirango ireme ryiza.

6. Fibre zikirahure zirashobora kuzamura imitungo ya ruswa hamwe nibiranga smc. Urupapuro ruhindura uruganda rusanzwe ruhitamo ibirahuri byaciwe ibirahuri byaciwe nkibikoresho byo gushimangira. Gukoresha cyane bizakora byoroshye ibicuruzwa byoroshye, kandi ikoreshwa rya dose nto cyane ntabwo rizagira ingaruka zigaragara kubicuruzwa. Imikoreshereze rusange ni 20%. Muri ubu buryo, ibicuruzwa birashobora icyarimwe guhura nibikorwa byombi byo kugaburira no kunyerera.

7. Umurimo yongera umutekano wa SMC no kuramba igihe cyo kubika. Kubera ko uwatangije styrene azabora buhoro, bigatera amasasu yibisimba, byongeramo umubare wa scavenger (intangarugero ikwiye) irashobora gutinda umuvuduko wa styrene kubora no gutembera. Abagizi babuza basanzwe banziquenones nibintu bya polvalent depolic.

Gushyira mu bikorwa urupapuro rwabumba ibicuruzwa

SMC ifite ibyiza byimikorere myiza y'amashanyarazi, ihohoterwa rikabije, igishushanyo cyoroshye, cyoroshye kandi cyoroshye kandi cyoroshye kandi cyoroshye kandi cyoroshye kandi cyoroshye, nibindi. Therefore, it is widely used in eight fields such as the automobile industry, railway vehicles, construction, electrical appliances, and communications (Table 1).

Muri bo, mu cyiciro cya mbere, cyakoreshejwe cyane cyane mu buryo bwo kwirinda imbaho ​​z'imirima, ibikoresho by'amashanyarazi, n'itumanaho, kandi ikoranabuhanga rikura. Nyuma yakoreshejwe mu nganda zimodoka kugirango usimbuze igice cyibyuma na aluminium Astoloy ibikoresho byumubiri kugirango bigabanye uburemere bwimodoka.

Muburyo bwo kugabanya ingufu zizigama kandi bisohokanamo ibinyabiziga bishya byingufu, Ikoranabuhanga ryibicuruzwa byimodoka bikomeje kwiteza imbere no kurushaza ubuziranenge. Kugeza ubu, Gushyira mu bikorwa ibikoresho bya SMC birashobora kugaragara ahantu hose mubuzima bwa buri munsi. Bigaragarira mu itumanaho ridafite umugozi, igikoma-gifatika cy'amashanyarazi, ibikoresho byo kwinjiza ubutaka, ubwiherero, no kwihuta gariyamoshi.

Incamake

Polyester idahujwe muri resin, umukozi witabira, kandi yuzuza urupapuro rubumba ahantu hatanga ibikoresho kubicuruzwa no kongera imbaraga. Thickener, irekura umukozi, fibre yikirahure, hamwe na polymerator yongeramo viso, kurwanya ruswa, ibihangange, ubushishozi, hamwe nibicuruzwa byubaka ibicuruzwa. Ibicuruzwa nkibi byakoreshejwe mumirima umunani ikomeye harimo inganda zimodoka hamwe nimodoka ya gari ya moshi. Mubikorwa biriho byingufu, kurengera ibidukikije, hamwe no gukoresha ingufu nke, inganda zimodoka zashyizeho ibisabwa byinshi nibikoresho bya SMC bitewe nibisabwa byabo byoroheje. Niyihe mbaraga nyamukuru yo gutera imbere ikoranabuhanga rya SMC.
