Mabwenzi ambiri m'moyo amakhala ndi chidziwitso chodziwika bwino cha mapulasitiki.Lero, ndikutengerani kuti mumvetsetse mayina ndi kugwiritsa ntchito zida zingapo zofunika kukuthandizani kusiyanitsa ndikuyika m'magulu atsiku ndi tsiku.
ABS: ABS ndi thermoplastic kupanga polima utomoni.Ili ndi zinthu zabwino zokhazikika ndipo imatha kukonzedwa kuti igwirizane ndi zosowa zapadera.Maonekedwe a thupi ndi ovuta komanso olimba.Itha kukhalanso ndi mphamvu zopondereza pamatenthedwe otsika, kuuma kwakukulu, kulimba kwamakina, kukana bwino kwa abrasion, mphamvu yokoka yopepuka, komanso chilozera cha kutentha mpaka 80c.Itha kukhalanso ndi bata labwino pa kutentha kwakukulu, kupewa moto, njira yosavuta, gloss yabwino, Ndi yosavuta kukongoletsa komanso imakhala ndi mtengo wotsika kuposa ma thermoplastics ena.Amagwiritsidwa ntchito kwambiri pazinthu zapakhomo ndi zoyera.
PP: Nkhaniyi inayamba kukula m’ma 1930.Panthawiyo, ankagwiritsidwa ntchito makamaka pa chipangizo chapamwamba chozungulira cha galasi lachitetezo.Kuphatikizika koyenera kwa kuwonekera ndi kupepuka kunapangitsa kukhala mtundu watsopano wosangalatsa wa pulasitiki.Pofika m'ma 1960, zinthuzi zidapezeka ndi opanga mipando ya avant-garde ndipo amagwiritsidwa ntchito mumipando yamakono ndi malo ena amkati.Zinthuzo zimakhala ndi malo olimba ndipo zimazindikirika mosavuta ngati galasi pamene zimawonedwa patali.Ma flakes a PP amatha kugwiritsidwa ntchito ngati galasi lapamwamba kwambiri ndipo ndi oyenera kupanga zambiri.Njira zosiyanasiyana zopangira ndi kukonza, zosavuta kukonza zowoneka bwino, zowoneka bwino komanso zowoneka bwino, mtundu, zotsatira zapamtunda zomwe mungasankhe, kukana kwambiri kwa mankhwala ndi nyengo, kukana kwambiri kwa mankhwala ndi nyengo, kusindikiza kwakukulu Zitha kukhala zobwezerezedwanso kwathunthu, zowoneka bwino bwino, luso lapadera lamitundu ndi kufananiza mitundu, kulimba kwapamwamba komanso kulimba kwabwino.Zomwe zimagwiritsidwa ntchito: zowonetsera, zizindikiro zamalonda, zinthu zamkati, mipando, zida zowunikira, magalasi.
CA: Zogulitsa za CA zimakhala ndi kukhudza kofunda, zotsutsana ndi thukuta, komanso zodziunikira zokha.Ndi polima yachikhalidwe yokhala ndi mitundu yowala komanso kuwonekera ngati madzi.Zapangidwa kuyambira koyambirira kwa zaka za m'ma 1900, ngakhale kale kuposa kutsekereza Bakelite.Chifukwa cha mawonekedwe ake ngati nsangalabwi, nthawi zambiri anthu amatha kuyiyika pazogwirira zida, mafelemu owonera, zida zatsitsi ndi zinthu zina, kotero ndi imodzi mwama polima odziwika bwino.Kugwiritsa ntchito ngati zida zopangidwa ndi manja kungaphatikizepo kukana kwake kwamphamvu kwambiri komanso kumva bwino.Chigawo chodziwonetsera chokha muzinthucho chimachokera ku kufewa kwake, ndipo zokopa pang'ono pamtunda zimatha kutha.Lili ndi zinthu za thonje ndi matabwa (ma cellulose) ndipo zimatha kupangidwa ndi jekeseni, kutengerapo ndi kutulutsa.Lili ndi otsika matenthedwe madutsidwe, kupanga kusinthasintha, zosiyanasiyana zowoneka zotsatira, fluidity kwambiri, zabwino pamwamba gloss, wabwino kutchinjiriza magetsi, odana ndi malo amodzi, kudziona kuwala, mkulu transparency, amphamvu kukaniza kukaniza, wapadera pamwamba masomphenya, ndi recyclable s zinthu.Zomwe zimagwiritsidwa ntchito nthawi zambiri zimaphatikizapo: zogwirira ntchito, zotengera tsitsi, zoseweretsa, magalasi ndi zipewa, mafelemu a magalasi, misuwachi, zogwirira pa tebulo, zisa, zolakwika za zithunzi.
PET: Nthawi zambiri PET amagwiritsidwa ntchito popaka zakudya ndi zakumwa zozizilitsa kukhosi.Komabe, chifukwa mowa umamva kutentha kwa mpweya ndi carbon dioxide, PET si yoyenera mowa.Pali zigawo zonse za 5 za mabotolo apulasitiki, ndipo zigawo ziwiri zomwe zili pakati pa PET ndi kuwonongeka kwa okosijeni, zomwe zingalepheretse mpweya kulowa ndi kutuluka.Kampani ya Miller Beer, yomwe idapanga botolo loyamba la mowa wa pulasitiki mu 2000, idati mabotolo apulasitiki amatha kukhala ozizira kuposa zitini za aluminiyamu, komanso kukhala ndi zotsatira zofanana ndi mabotolo agalasi.Zitha kutsekedwanso ndipo sizimathyoka mosavuta.Recyclable (PET ndi imodzi mwazitsulo zapulasitiki zomwe zimatha kubwezeredwanso), kukana kwamankhwala kwabwino, kulimba komanso kulimba, kupukuta bwino kwambiri pamwamba, komanso kukana kupanikizika.Zomwe zimagwiritsidwa ntchito: kulongedza zakudya, zinthu zamagetsi, mabotolo a zakumwa zozizilitsa kukhosi, mabotolo a mowa wa Miller.
Pali mitundu yambiri ya zida zapulasitiki, komanso kumvetsetsa bwino koyambira kumatha kusankha bwino zinthu zapakhomo zomwe zili bwino pamoyo watsiku ndi tsiku, zomwe ndi zabwino pa moyo wa anthu.
