Anhydride Phthalic Premium (PA): Te Poraka Hanga Matua mō ngā Polymers me ngā Matū Mahi-Tiketike
Ngā Āpure Tono Matua
1. Ngā Resin Polyester me ngā Thermoplastics: Te Matua o ngā Polymers Ahumahi
Ko te Phthalic Anhydride te mea matua e whakamahia ana i roto i te hanga o ngā kapia polyester kāore i te mākū (UPR), he wāhanga nui i roto i ngā kirihou whakakaha-muka karāhe (FRP):
Ngā tono FRP:
I roto i te hanga waka (hei tauira, ngā kaihanga waka Pākehā), ka whakamahia ngā UPR i ahu mai i te PA hei hanga i ngā panera tinana māmā, ngā parepare, me ngā wāhanga o raro i te taupoki, hei whakaiti i te taumaha o te waka me te whakapai ake i te pai o te whakamahinga wahie.
I roto i te pūngao hau, he mea nui ngā kapia PA mō te hanga i ngā mata o ngā tāhū hau, e whakarato ana i te kaha me te manawanui ki te tu atu i ngā āhuatanga huarere kino i ngā pāmu tai (hei tauira, ngā kaupapa o Te Moana-a-Kiwa).
Ngā Tāpiringa Kirihou:
He mea whakarerekē i roto i te hanga polyvinyl chloride (PVC), e whakarei ake ana i te ngāwari me te ngāwari o te tukatuka. Hei tauira, i roto i ngā wheketere paipa PVC o Āhia, ka whakapai ake ngā kirihou PA-hangai i te ātete pānga o ngā paipa mō ngā pūnaha wai me te paru.
2. Ngā Peita, Ngā Paninga, me Ngā Piripiri: Te Mahi me te Pakari
Ngā Resini Āriki:
He wāhanga matua te PA i roto i ngā kapia alkyd, e whakamahia ana i roto i ngā peita hoahoanga (hei tauira, ngā peita whare o waho i Amerika Te Raki) nā te mea he tino ātete ki te huarere me te pupuri tae. Ka tiakina hoki e ngā paninga alkyd ngā mata whakarewa i roto i ngā taiao ahumahi (hei tauira, ngā piriti, ngā mīhini) mai i te waikura.
Ngā Paninga Epoxy:
I roto i ngā paninga hiato, ka whakarei ake ngā matū PA i te piri me te ātete matū o ngā pūnaha epoxy, he mea nui mō ngā papa i roto i ngā rūma horoi rongoā me ngā whare tukatuka kai.
Ngā piripiri:
Whakamahia ai i roto i ngā piripiri rewa-wera (热熔胶) mō te takai me te here pukapuka, ka whakapai ake te PA i te ira rewa me te kaha here, kia pono ai te mahi i roto i ngā raina hanga tere-rahi (hei tauira, ngā ahumahi takai o Ūropi).
3. Ngā Kaiwhakaahua me ngā Matū Motuhake: Te Whakapai Ake i ngā Āhuatanga o ngā Rauemi
Ngā Kaiwhakaahua Phthalate:
Ko te PA te matūriki mō te whakaputa i te diisononyl phthalate (DINP) me te diethyl phthalate (DEP), e whakamahia whānuitia ana i roto i ngā hua PVC pēnei i ngā taonga takaro, ngā kakahu whakapaipai, me ngā taputapu hauora. Ka whakarei ake ēnei kirihou i te ngāwari me te pupuri tonu i te tutuki i ngā ture EU REACH mō te iti o te paitini (hei tauira, i roto i ngā hua tamariki).
Ngā Takawaenga Rongoā:
I roto i te hanganga rongoā, ka whakamahia ngā matū PA hei hanga i ngā rongoā pēnei i ngā rongoā ārai-mumura me ngā matū harore. Hei tauira, he wāhi nui tōna i roto i te hanganga o ngā paturopi cephalosporin, he mea nui mō te rongoā i ngā mate kitakita puta noa i te ao.
4. Ahuwhenua me te Whakahaere Pepeke: Ngā Otinga Tauwhiro
Ngā patu pepeke me ngā patu harore:
Ka whakamahia ngā matū kei roto i te PA i roto i te hanganga o ngā hua tiaki hua, pērā i ngā pyrethroid hangai hei whakahaere pepeke. I roto i ngā pāmu pīni soya o Amerika ki te Tonga, ka āwhina ēnei matū ki te tiaki i ngā hua mai i ngā pepeke whakaeke me te whakaiti i te pānga ki te taiao.
Ngā Pūmua Pirau-koiora:
Hei monomer i roto i ngā kirihou pirau-koiora, ka whai wāhi a PA ki te whanaketanga o ngā rauemi tākai e pai ana ki te taiao (hei tauira, ngā ipu kai tipu) e whakaiti ana i te whakawhirinaki ki ngā hua e ahu mai ana i te hinu.
5. Ngā tono mō te taiwhanga me te rangahau
Te Hanganga Ora:
He matū whai hua te PA i roto i ngā taiwhanga mātauranga me ngā taiwhanga ahumahi mō ngā tauhohenga pēnei i te Friedel-Crafts acylation, e whakamahia ana hei hanga i ngā ketone kakara me ngā tae. Ka āwhina hoki i te hanga o te phthalimide, he takawaenga matua i roto i te rangahau rongoā me te ahuwhenua.
Pūtaiao Pūmua:
Whakamahia i roto i ngā taiwhanga pūmua hei ako i ngā whanaungatanga hanganga-āhuatanga o ngā polyesters, e āhei ai te whakawhanake i ngā rauemi matatau mō te rererangi me te hikohiko (hei tauira, ngā paninga ātete-wera mō ngā amiorangi).
