Phthalic Anhydride (PA) yabulemu: Nchintu chiyandikana loko chakuyaka ma polymers amakemikalu aabeleka obotu
Zibeela Zipati Zyakubelesya
1. Ma Polyester Resins a Thermoplastics: Mukati wama Polymers
Phthalic Anhydride ibelesyegwa kapati mukupanga ma unsaturated polyester resins (UPRs), chintu chipati mumapulasitiki aajisi fiberglass (FRPs):
Kubelesya kwa FRP:
Mukupanga myootokala (nkokuti, basikupanga myootokala bakuYulopu), ma UPR azwa ku PA abelesyegwa kupanga zibeela zyamumubili zitakatazyi pe, mabbampa, azibeela zili munsi lyamootokala, ikucesya kulema kwamyootokala akusumpula kubelesya kabotu mafuta.
Munguzu zyamuwo, ma resini aazwa ku PA ngaayandika kapati mukupanga mabbaaji aamuwo, kupa nguzu zipati akuyuma kwachiindi chilamfu mumapulazi aali kunkomwe yalwizi (nkokuti, mapulojekiti aa Lwizi lwaNorth).
Ziyungizyo zya Thermoplastic:
Ibeleka mbuli chintu chisandula mukupanga polyvinyl chloride (PVC), ikusumpula kuchincha akukonzya kubelesegwa. Mbuli chitondeezyo, mumafakitoli aamapayipi aa PVC aakuEzhiya, mapulasitiki aajisi PA asumpula kukazyigwa kwamapayipi aameenda aamaanzi aakusowela tombe.
2. Mapenti, Zivwumbyo, a Zinamatika: Kuchita obotu akuyuma
Ma Alkyd Resins:
PA nchintu chipati mu alkyd resins, chibelesyegwa mukupenta zyakuyaka (nkokuti, penti zyaanze zyamaanda muNorth America) nkaambo kakukwabilila kwawo kuchiindi chilamfu akubamba mubala. Zivwumbyo zye Alkyd azyalo zilakwabilila zintu zyabutale mumasena aakupanga zintu (nkokuti, mabbulogwe, minchina) kuti zitanyonyooki.
Kuvwumba kwa Epoxy:
Muzisani zipangidwe antoomwe, PA derivatives zisumpula kujatana akukazyigwa kwamakemikalu kwa epoxy systems, nchintu chipati mukubamba bulo mumaanda aasalala aamisamu amumasena aabamba chakulya.
Zinamatika:
Ibelesyegwa mu 热熔胶 (ma hot-melt adhesives) mukupakila akubamba mabbuku, PA ilasumpula busena bwakunyenguluka akujatisya, kupa kuti kube kubeleka kabotu mumigwagwa yakupanga zintu zifwambaana (nkokuti, mumakkampani aaku Europe).
3. Zibelesyo zyapulasitiki azyamakemikalu aalibedelede: Kusumpula bube bwazintu
Phthalate Plasticizers:
PA ninzila yakupanga diisononyl phthalate (DINP) antoomwe a diethyl phthalate (DEP), iibelesyegwa kapati muzintu zya PVC mbuli zisobano, zyakusama, azibelesyo zyabusilisi. Aaya mapulasitiki asumpula kuchincha-chincha mpawo akutobela milawu ya EU REACH yakukwabilila kucheya (nkokuti, muzintu zyabana).
Zibelesyo zyaakati-akati zyamisamu:
Mukupanga misamu, misamu iizwa ku PA ilabelesyegwa mukupanga misamu mbuli misamu iilwana kuzimba alimwi amisamu iilwana tuzunda. Mbuli chitondeezyo, chilagwasya mukupanga ma antibiotics aa cephalosporin, aayandika kapati mukusilisya malwazi aaletwa atuzunda munyika yoonse.
4. Bulimi akulesya tuzunda: Nzila zitamani
Minsamu iijaya tuzunda aMisamu iijaya tuzunda:
Makemikalu aazwa ku PA abelesyegwa mukupanga misamu yakukwabilila zilyo, mbuli ma pyrethroids aabelesyegwa kulwana tuzunda. Mumapulazi aa soybean aakuSouth America, misamu eeyi ilagwasya kukwabilila zilyo kuzwa kuzisyango zikonzya kunjila mpawo kazicesya ntenda kubusena.
Ma polymer aakonzya kubola:
Mbuli monomer mumapulasitiki aakonzya kubola, PA ilagwasya mukupanga zintu zitanyonganyi busena (nkokuti, ziyobwedo zyazyakulya zipangwa azisyango) eezyo zicesya kusyoma zintu zipangwa amafuta.
5. Kubelesya kwa laboratory akuvwuntauzya
Kupanga zintu zipona:
PA nchintu chibelesegwa munzila zyiingi muma laboratory aakuyiisya amumakkampani aakuchita zintu zilimbuli Friedel-Crafts acylation, ibelesyegwa kupanga ma ketones amadayi aanunkilila. Alimwi chigwasya kupanga musamu wa phthalimide, musamu uuyandika kapati mukuvwuntauzya misamu azyabulimi.
Sayensi ya Polymer:
Kubelesyegwa muma laboratory aa polymer kwiiya bupange-bube bwama polyesters, kupa kuti kube kupanga zintu zisumpukide zyakubelesya mujulu azyamagesi (nkokuti, zintu zikwabilila kupya kwa satellites).

Nkaambo nzi ncotweelede kusala Phthalic Anhydride yesu?
Nikuba kuti uli mukupanga zintu zipya, kupanga zintu zyakuvwumba zibeleka obotu, naakuti kupanga mapulasitiki aatamani, PA yesu ilapa kusalala akusalala. Kakuli masena aakusambalila zintu munyika yoonse muNorth America, Europe, antoomwe aEzhiya, tulasinizya kuti zintu zyakusambala zilasyomeka antoomwe alugwasyo lwazyabusongo muzintu zizwa kumakkampani mapati kusikila kumapulojekiti aakuvwuntauzya.
