Nau'ikan Polymers: Iri-iri na Kayan Aiki da ke Juyin Juya Halin Duniya
Polymers mahadi ne da aka haɗa da manyan ƙwayoyin halitta waɗanda aka samar ta hanyar gyaggyara ƙananan ƙwayoyin halitta da ake kira monomers. Polymers suna zuwa ta hanyoyi daban-daban kuma suna da halaye iri-iri, wanda hakan ya sa su zama kayan aiki masu amfani sosai. A cikin wannan labarin, za mu bincika nau'ikan polymers da aka fi sani, yadda suke aiki, da kuma amfaninsu a rayuwar yau da kullun.
Na Halitta da Na roba Polymers
Ana iya rarraba polymers zuwa manyan nau'i biyu: polymers na halitta da polymers na roba. polymers na halitta sune waɗanda ake samu a yanayi, yayin da polymers na roba sune waɗanda ake samarwa ta hanyar hanyoyin sinadarai a dakunan gwaje-gwaje ko masana'antu.
Na Halittar Polymers
Ana samun polymers na halitta a cikin kayan halitta da yawa waɗanda mutane suka yi amfani da su tsawon dubban shekaru. Wasu muhimman misalan polymers na halitta sune:
1. Cellulose: Wannan polymer da ake samu a bangon ƙwayoyin shuka shine mafi yawan sinadarai a Duniya. Ana amfani da Cellulose don yin takarda, kwali, da wasu yadi.

4. Polystyrene (PS): Ana amfani da shi wajen ƙera marufin abinci, kayan aikin gida, da sauran kayayyakin yau da kullum.
5. Polyamide (Nylon): An san shi da ƙarfi da juriya ga gogewa. An fara amfani da Nailan a matsayin madadin siliki a cikin parachutes sannan daga baya a cikin tufafi da aikace-aikacen masana'antu daban-daban.
Polymers na Thermoplastic da Thermosetting
Baya ga rarrabuwarsu ta asali, ana iya bambanta polymers ta hanyar yadda suke amsawa ga zafi. Akwai manyan nau'ikan guda biyu: thermoplastics da thermosets.
Thermoplastic
Polymers na thermoplastic suna narkewa idan aka dumama su kuma suna sake taurarewa idan aka sanyaya su. Wannan siffa yana sa su zama masu sauƙin sake amfani da su. Wasu misalan polymers na thermoplastic sune:
1. Acrylonitrile Butadiene Styrene (ABS): Ana amfani da shi wajen kera kayan wasa, kayan mota, da kayan kicin. An san wannan kayan da ƙarfi da kwanciyar hankali.
2. Polycarbonate (PC): Ana amfani da shi wajen yin gilashin ido, CD, da kayan lantarki. Polycarbonate yana da haske sosai da juriya ga tasirinsa.
Saitin Thermose
Ba za a iya narkar da polymers na Thermoset ba bayan an fara dumamawa da taurarewa. Suna samar da tsari mai ƙarfi da dorewa. Wasu misalan polymers na thermosetting sune:
1. Bakelite: Ɗaya daga cikin polymers na farko da aka ƙirƙira na thermosetting. Ana amfani da shi a cikin kayan lantarki, maɓallan wuta, da kuma wuraren riƙe tukunya saboda kyawawan halayensa na rufewa da wutar lantarki.
2. Epoxy: Ana amfani da shi a cikin manne mai ƙarfi, murfin kariya, da kayan haɗin gwiwa. An san Epoxy saboda juriyarsa ga sinadarai, zafi, da ƙarfin mannewa.
Injiniyoyi masu amfani da sinadarai
Polymers na injiniyanci polymers ne masu kyawawan halayen injiniya, zafi, da sinadarai. Ana amfani da su a aikace-aikacen da ke buƙatar ƙarin dorewa da dorewa. Misalan polymers na injiniyanci sun haɗa da:
1. Polyether Ether Ketone (PEEK): Wannan polymer yana da juriya mai zafi da kuma juriyar sinadarai masu kyau. Amfaninsa ya haɗa da abubuwan da ke cikin jirgin sama, na'urorin likitanci, da aikace-aikacen mota.
2. Polyphenylene Sulfide (PPS): An san shi da juriyar sinadarai da injina, ana amfani da PPS a masana'antar kera motoci, kayan lantarki, da kayan gida.
elastomer
Elastomers wani nau'in polymer ne mai yawan sassauci, wanda ke ba da damar yin babban nakasa ba tare da fashewa ko karyewa ba. Elastomers na iya komawa ga siffarsu ta asali bayan an miƙe su ko an lanƙwasa su. Wasu misalan elastomers sune:
1. Robar da aka yi da roba: Kamar robar nitrile da robar silicone, waɗanda ake amfani da su a aikace-aikacen motoci, likitanci, da masana'antu saboda juriyarsu ga mai, zafin jiki, da sinadarai.
2. Polyurethane (PU): Ana amfani da shi a cikin kumfa, manne, da shafi. Polyurethane yana da kyakkyawan juriya ga lalacewa da lalacewa.
Haɗaɗɗun Polymer
Haɗaɗɗen polymer sune kayan da aka ƙirƙira ta hanyar haɗa polymers tare da zare ko barbashi daban-daban don cimma kyawawan halayen abu. Misalan haɗaɗɗen polymer sun haɗa da:
1. Carbon Fiber: Ana amfani da shi a fannin jiragen sama, motoci, da wasanni saboda ƙarfinsa mai yawa da kuma sauƙin nauyi.
2. Fiberglass: Ana amfani da shi wajen kera jiragen ruwa, kayan aikin mota, da kayayyakin gida.
Mai sarrafa polymer
Polymers masu sarrafawa polymers ne waɗanda ke da ikon gudanar da wutar lantarki. Ana amfani da su a aikace-aikacen lantarki da firikwensin. Misalan polymers masu sarrafawa sune:
1. Polypyrrole: Ana amfani da shi wajen amfani da na'urori masu auna firikwensin da kuma kayan adana makamashi.
2. Polyaniline: Yana da amfani a cikin eriya, allon taɓawa, da kayan lantarki masu sassauƙa.
Kammalawa
Sinadaran polymer suna da matuƙar muhimmanci a rayuwarmu ta zamani. Ana amfani da su a kusan kowane fanni na rayuwarmu, tun daga tufafi da abinci zuwa magunguna har ma da kayan fasaha na zamani. Da fahimtar nau'ikan polymer da amfaninsu, za mu iya fahimtar muhimmancin waɗannan kayan wajen tsara duniyar zamani. Ƙirƙirar fasaha a fannin polymer yana ci gaba, yana alƙawarin sabbin abubuwan da aka gano na kayan aiki masu ƙarfi, masu sauƙi, da kuma waɗanda ba sa cutar da muhalli a nan gaba.
