ʻO ka resin polyester unsaturated ka ʻano resin thermosetting i hoʻohana pinepine ʻia, ʻo ia hoʻi kahi hui polymer linear me nā pilina ester a me nā pilina pālua unsaturated i hoʻokumu ʻia e ka condensation o ka waikawa dicarboxylic unsaturated me nā diols a i ʻole ka waikawa dicarboxylic saturated me nā diols unsaturated. ʻO ka maʻamau, hana ʻia ka hopena condensation polyester ma 190-220 ℃ a hiki i ka hiki ʻana i ka waiwai waikawa i manaʻo ʻia (a i ʻole ka viscosity). Ma hope o ka pau ʻana o ka hopena condensation polyester, hoʻohui ʻia kahi nui o ka vinyl monomer i ka wā wela e hoʻomākaukau i kahi wai viscous. Ua kapa ʻia kēia hopena polymer he resin polyester unsaturated.
Ua hoʻokō ka resin polyester unsaturated i ka holomua nui ma nā ʻoihana he nui, e like me ka hana ʻana i ka windsurfing a me nā yachts i nā haʻuki wai. ʻO kēia polymer ka mea nui o ka hoʻololi maoli i ka ʻoihana kūkulu moku, no ka mea hiki iā ia ke hāʻawi i ka hana maikaʻi loa a me ka maʻalahi kiʻekiʻe loa i ka hoʻohana ʻana.
Hoʻohana pinepine ʻia nā resins polyester unsaturated i ka ʻoihana kaʻa ma muli o ko lākou hoʻolālā versatility, māmā ke kaumaha, haʻahaʻa ke kumukūʻai ʻōnaehana, a me ka ikaika mechanical haʻahaʻa.
Hoʻohana ʻia kēia mea i nā hale, ʻoi aku hoʻi i ka hana ʻana i nā ipu kuke, nā kapuahi, nā tile kaupaku, nā mea pono o ka lumi ʻauʻau, a me nā paipu a me nā pahu wai.
ʻOkoʻa nā noi o ka resin polyester unsaturated. ʻO ka ʻoiaʻiʻo, ʻo nā resins polyester kekahi o nā mea piha loa
nā hui i hoʻohana ʻia ma nā ʻano ʻoihana like ʻole. ʻO nā mea nui loa, a me nā mea i hōʻike ʻia ma luna nei, penei:
* Nā mea i hui pū ʻia
* Nā pena lāʻau
* Nā panela laminated pālahalaha, nā panela corrugated, nā panela ribbed
* ʻAʻahu gel no nā waʻa, nā mea hana kaʻa a me ka lumi ʻauʻau
* Nā mea hoʻopili kala, nā mea hoʻopihapiha, nā stucco, nā putties a me nā hoʻopaʻa kemika
* Nā mea i hoʻohui ʻia e hoʻopau ponoʻī ana
* Quartz, kinikini a me ka sima hana
