Hoʻohui ʻia a me ka hoʻohana ʻana i ka hui hoʻoheheʻe pepa

ʻO ka hui hoʻoheheʻe pepa e pili ana i ka resin polyester unsaturated e like me ke kino nui, e hoʻohui ana i ka lāʻau lapaʻau, ka mea hoʻokuʻu mold, filler, haʻahaʻa shrinkage agent, thickener, etc. Molding compound i uhi ʻia me ka polyethylene (PE) film.Hōʻike pōkole kēia pepa i ka haku mele ʻana a me ka hoʻopili ʻana o ka SMC.

Ka Hoʻohui ʻia ʻana o ka Hui Hoʻohui Pepa

Hoʻokumu ʻia ka SMC me ka resin polyester unsaturated, crosslinking agent, initiator, filler, thickener, release agent, glass fiber, and polymerization inhibitor.I waena o lākou, ʻo nā ʻāpana mua ʻehā e hāʻawi nui i ka hoʻolālā waiwai no nā huahana a hoʻonui i ka ikaika.ʻO nā ʻāpana ʻehā hope loa no nā waiwai o ka hoʻonui ʻana i ka viscosity, ka pale ʻana i ka corrosion, insulation, a me ka paʻa o ka huahana.

1. ʻO ka resin polyester unsaturated a me nā mea hana crosslinking ke kino nui o SMC.Hoʻopili pinepine ʻia nā resins polyester unsaturated mai nā ʻakika dicarboxylic unsaturated (a i ʻole anhydride), nā waikawa dicarboxylic saturated (a i ʻole anhydride), a me nā polyols.Loaʻa iā ia kekahi mau ʻano mechanical a me ka ikaika, a ua like ka ikaika o loko.ʻO ka mea hana crosslinking ka nui o styrene.Ma hope o ka hoʻopaʻa ʻia ʻana o nā mea ʻelua, ʻo ia nā mea nui no ka mālama ʻana i ka plasticity o ka huahana, e pāʻani ana i ke kuleana o ka pilina, kākoʻo, ka hoʻouna ʻana i ke kaulike, a me ka pale.

2. Ho'ōla ka mea hoʻomaka i ka resin a me ka crosslinker e ho'ōla a hoʻokumu i ka pae resin paste.ʻO kāna hana ka mea nui e hana i ka resin a me ka paʻa pālua i ka monomer cross-linking e like me styrene copolymerize i hiki ke hoʻopaʻa ʻia ka SMC a hoʻokumu ʻia i loko o ka lua mold.

3. Noho ka mea hoʻopihapiha ma mua o hoʻokahi hapakolu o ka hui hoʻoheheʻe pepa a hiki ke hoʻololi i ka viscosity o ka hui hoʻoheheʻe.Pono e loaʻa nā hiʻohiʻona o ka haʻahaʻa kikoʻī haʻahaʻa, haʻahaʻa ka waiwai adsorption ʻaila, liʻiliʻi pores, pale ʻana i ka corrosion, a me ke kumu kūʻai haʻahaʻa.ʻO nā mea hoʻopihapiha maʻamau i hoʻohana nui ʻia ʻo CaCO3, Al(OH)3, a pēlā aku.

4. Hāʻawi nā mea mānoanoa iā SMC i kahi waiwai kiʻekiʻe-viscosity, non-sticky.ʻO ka hoʻomākaukau ʻana i ka pepa a me nā pūhui hoʻoheheʻe nui e pono ai i ka viscosity haʻahaʻa o ka resin e hoʻomaʻamaʻa i ka impregnation o ke aniani aniani a me ka hoʻopiha ʻana e ka resin.A koi ʻia ka hoʻoheheʻe ʻana i ka viscosity kiʻekiʻe.No laila, pono e hoʻohui i kahi mānoanoa ma mua o ke kaʻina hana e hoʻohuli i ka viscosity haʻahaʻa o ke aniani fiber impregnation i kahi viscosity kiʻekiʻe ʻaʻole pili.

5. Kāohi ka mea hoʻokuʻu i ka hui hoʻoheheʻe pepa mai ka loaʻa ʻana o ka pilina me ka ʻili o ka metala.Hiki i ka mea hoʻokuʻu ke pale aku i ka resin polyester unsaturated mai ka launa pū ʻana me ka ʻili o ka ʻōpala metala i ka wā o ke kaʻina plastik o ka hui resin.ʻO ka nui o nā ʻakika momona a i ʻole nā ​​paʻakai i hōʻike ʻia e ka zinc stearate.ʻO ka hoʻohana nui ʻana e hōʻemi maʻalahi i ka hana o ka huahana.ʻO ka hoʻohana maʻamau no 1 ~ 3% o ka huina huahana e hōʻoia i ka maikaʻi o ka huahana.

6. Hiki i nā pulu aniani ke hoʻoikaika i ka pale ʻana i ka corrosion a me nā waiwai insulation o SMC.E koho ma'amau ka hui wili pepa i nā moena fiber aniani i mea hooikaika.ʻO ka hoʻohana nui ʻana e hana maʻalahi i ka huahana, a ʻo ka hoʻohana ʻana i kahi maʻi liʻiliʻi ʻaʻole e loaʻa kahi hopena ikaika i ka huahana.ʻO ka hoʻohana maʻamau ma kahi o 20%.Ma kēia ala, hiki i ka huahana ke hoʻokō i nā kaʻina ʻelua o ka hoʻoheheʻe extrusion a me ka hoʻoheheʻe ʻana.

7. Hoʻonui ka Inhibitor i ka paʻa o SMC a hoʻolōʻihi i ka manawa mālama.No ka mea, e decompose lohi ka styrene hoʻomaka, e hoʻoulu ai i ka polymerization o ka resin, me ka hoʻohui ʻana i ka nui kūpono o ka scavenger radical manuahi (polymerization inhibitor) hiki ke hoʻolohi i ka wikiwiki o ka decomposition styrene a hoʻolōʻihi i kona manawa mālama.He mau benzoquinones a me nā pūhui phenolic polyvalent.

Hoʻohana ʻana i nā Huahana Hui Pū ʻIa Pepa

Loaʻa iā SMC nā mea maikaʻi o ka hana uila maikaʻi loa, ke kūpaʻa corrosion ikaika, māmā, maʻalahi a maʻalahi hoʻi ka hoʻolālā ʻenekinia, a me nā mea ʻē aʻe.No laila, hoʻohana nui ʻia ia ma nā kahua ʻewalu e like me ka ʻoihana kaʻa, nā kaʻa kaʻaahi, ke kūkulu ʻana, nā mea uila, a me nā kamaʻilio (Papa 1).

I waena o lākou, i ka wā mua, ua hoʻohana nui ʻia ia ma ke ʻano o nā papa insulating i nā kahua o ke kūkulu ʻana, nā mea uila, a me nā kamaʻilio, a ʻoi aku ka ʻenehana.A laila ua hoʻohana ʻia i loko o ka ʻoihana kaʻa e pani i kahi ʻāpana o ke kila a me nā mea alumini alumini o ke kino e hoʻemi i ke kaumaha o ke kaʻa.

Ma lalo o ke kumu o ka mālama ʻana i ka ikehu o kēia manawa a me ka hoʻohaʻahaʻa ʻana a me ka hoʻomohala ʻana i nā kaʻa ikehu hou, hoʻomau ka ʻenehana o nā huahana automotive i ka māmā a me ke ʻano kiʻekiʻe.A hiki i kēia manawa, hiki ke ʻike ʻia ka noi ʻana o nā mea SMC ma nā wahi āpau i ke ola o kēlā me kēia lā.Hōʻike ʻia ia i loko o nā kamaʻilio uea ʻole, nā pahū uila hōʻoiaʻiʻo i ka pahū, nā mea hoʻokaʻawale honua, nā lumi ʻauʻau, a me nā keʻena kaʻaahi kiʻekiʻe.

Papa 1 ʻEwalu mau noi nui a me nā māhele māhele o nā mea SMC

Hōʻuluʻulu

ʻO ka resin polyester unsaturated, crosslinking agent, initiator, a me ka mea hoʻopihapiha i loko o ka pūhui molding sheet e hāʻawi i kahi kumu waiwai no ka huahana a hoʻonui i ka ikaika hana.ʻO ka mea mānoanoa, ka mea hoʻokuʻu, ka fiber aniani, a me ka polymerization inhibitor e hoʻohui i ka viscosity, corrosion resistance, insulation, a me ka paʻa o ke kūkulu ʻana i ka huahana.Ua hoʻohana ʻia ia mau huahana i ʻewalu mau kahua nui me ka ʻoihana kaʻa a me nā kaʻa kaʻaahi.Ma lalo o ke ʻano o ka mālama ʻana i ka ikehu, ka mālama ʻana i ke kaiapuni, a me ka hoʻohana ʻana i ka ikehu haʻahaʻa, ua kau ka ʻoihana kaʻa i nā koi kiʻekiʻe a kiʻekiʻe aʻe no nā mea SMC ma muli o kā lākou koi māmā.ʻO ia ka mea hoʻoikaika nui no ka hoʻomohala ʻana i ka ʻenehana SMC.

E hoʻohana i kamīkini paʻi hydraulic compositee paʻi i nā huahana hoʻohuihui pepa.He loea ʻo Zhengxihale paʻi hydraulic ma Kina, hāʻawi i nā paʻi kiʻekiʻe.E kelepona iā mākou no ka loaʻa ʻana o nā kikoʻī.
