ʻO ka resin polyester unsaturated ka mea maʻamau i hoʻohana pinepine ʻia i ka resin thermosetting, ʻo ia ka mea maʻamau he hui polymer linear me nā paʻa ester a me nā paʻa pālua unsaturated i hana ʻia e ka condensation o ka waika dicarboxylic unsaturated me nā diols a i ʻole ka waikawa dicarboxylic saturated me nā diols ʻole. ʻO ka maʻamau, lawe ʻia ka hopena condensation polyester ma 190-220 ℃ a hiki i ka waiwai waika i manaʻo ʻia (a i ʻole viscosity). Ma hope o ka pau ʻana o ka hopena condensation polyester, hoʻohui ʻia kahi nui o ka monomer vinyl i ka wā wela e hoʻomākaukau ai i kahi wai viscous. Kapa ʻia kēia ʻano hoʻonā polymer i ka resin polyester unsaturated.
Ua loaʻa i ka resin polyester unsaturated ka lanakila nui ma nā ʻoihana ʻoihana he nui, e like me ka hana ʻana i ka windsurfing a me nā yachts i nā haʻuki wai. ʻO kēia polymer ke kumu o ka hoʻololi maoli i ka ʻoihana hana moku, no ka mea hiki iā ia ke hāʻawi i ka hana maikaʻi loa a me ka loli kiʻekiʻe loa i ka hoʻohana.
Hoʻohana pinepine ʻia nā resins polyester unsaturated i ka ʻoihana kaʻa ma muli o kā lākou hoʻolālā versatility, ke kaumaha māmā, ke kumu kūʻai haʻahaʻa, a me ka ikaika mechanical haʻahaʻa.
Hoʻohana pū ʻia kēia mea i nā hale, ʻoi aku hoʻi i ka hana ʻana i nā mea kuke, nā kapuahi, nā pā hale, nā mea ʻauʻau ʻauʻau, a me nā paipu a me nā pahu wai.
He ʻokoʻa ka hoʻohana ʻana o ka resin polyester unsaturated. ʻO nā resins polyester e hōʻike ana i kekahi o nā mea paʻa
nā mea hoʻohui i hoʻohana ʻia i nā ʻano ʻoihana ākea. ʻO nā mea nui loa, a me nā mea i hōʻike ʻia ma luna nei:
* Mea hoʻohuihui
* Pena laau
* Nā paneli laminated pālahalaha, nā ʻāpana ʻāwili, nā ʻāpana ribbed
* ʻO ka lole gel no nā waʻa, nā kaʻa a me nā hale ʻauʻau
* ʻO nā pāpaʻi kala, nā mea hoʻopihapiha, nā stucco, nā putties a me nā heleuma kemika
* Nā mea hoʻohuihui hoʻopau iā ia iho
* Quartz, ke kinikini a me ka sima hana
