Kodi Polymer ndi chiyani?

Yankho la funso loti polima ndi chiyani ngati liwu lotanthawuza lingaperekedwe ngati kuphatikiza kwa mawu achilatini akuti "poly" kutanthauza ambiri ndi "mer" kutanthauza mayunitsi obwerezabwereza. Polima nthawi zambiri amagwiritsidwa ntchito mofanana ndi pulasitiki kapena utomoni m'makampani opanga mankhwala. M'malo mwake, polima imaphatikizapo zinthu zingapo zokhala ndi zinthu zosiyanasiyana. Amapezeka muzinthu zambiri zapakhomo zomwe zimagwiritsidwa ntchito m'moyo watsiku ndi tsiku, zovala, zoseweretsa, komanso zofunika kwambiri muzomangamanga zomwe zimagwiritsidwa ntchito potsekereza.

Polima ndi mankhwala omwe mamolekyu ake amalumikizidwa pamodzi mu unyolo wautali, wobwerezabwereza. Chifukwa cha kapangidwe kake, ma polima ali ndi zinthu zapadera zomwe zitha kusinthidwa kuti zigwiritsidwe ntchito mosiyanasiyana. Ma polima amagawidwa m'mitundu iwiri: zachilengedwe komanso zopangidwa. Rubber, mwachitsanzo, ndi zinthu zachilengedwe za polymeric zomwe zakhala zikugwiritsidwa ntchito kwa zaka zikwi zambiri. Ili ndi mikhalidwe yabwino kwambiri yotanuka chifukwa cha unyolo wa ma polima opangidwa mwachilengedwe.

Polima zachilengedwe zomwe zimapezeka kwambiri padziko lapansi ndi cellulose, organic pawiri yomwe imapezeka m'makoma a zomera. Cellulose nthawi zambiri amagwiritsidwa ntchito popanga zinthu monga mapepala ndi nsalu. Ma polima opangidwa ndi anthu amaphatikiza zinthu mongapolyethylenendi polystyrene, mapulasitiki odziwika kwambiri padziko lonse lapansi, omwe amapezeka muzinthu zambiri. Ma polima ena opangidwa amatha kupindika, pomwe ena amakhala okhazikika mpaka kalekale.

Kodi Makhalidwe a Polymers ndi Chiyani?

Kugwira ntchito kwa zinthu zomwe zimawonjezera kulimba pantchito zomanga ndizofunikira kwambiri. Zigawo za mankhwala omwe amawonjezera moyo wa nyumba ndi kupanga malo okhala bwino ayeneranso kukhala pamlingo wokwanira. Chifukwa chake, zida za polima zimawonekera ndi zinthu zambiri zosiyanasiyana. Ma polima omwe amatha kupangidwa m'malo opangira mankhwala amatha kukhala ndi zomwe amafunikira malinga ndi malo omwe amagwiritsidwa ntchito.

Chifukwa cha zinthuzi, ma polima amakhala osagwirizana ndi zovuta zomwe zimatha kukumana nazo ndikukhala m'gulu lazinthu zoyenera kupanga mankhwala omanga. Zida zomangira polima zomwe zimagonjetsedwa ndi madzi ndi mankhwala chifukwa chake ndizodziwika kwambiri.

Mitundu ya ma polima ndi iti?

Kuphatikiza pa mafunso oti polima ndi chiyani komanso zinthu zake, nkhani ina yofunika kuyankhidwa ndi mitundu yanji ya ma polima omwe amapezeka pamsika. Ma polima amagawidwa m'magulu awiri akuluakulu: thermoplastics, ndi thermosets. Chofunikira kwambiri chomwe chimapangitsa kusiyana pakati pa mitundu ya polimayi ndi momwe amachitira akakumana ndi kutentha.

1. Thermoplastics

Thermoplastics ndi utomoni womwe umakhala wolimba kutentha koma umasanduka pulasitiki komanso wofewa ukatenthedwa. Pambuyo pokonzedwa, nthawi zambiri ndi jekeseni kapena kuwombera, thermoplastics imatenga mawonekedwe a nkhungu yomwe imatsanuliridwa ngati kusungunula ndikukhazikika mu mawonekedwe omwe mukufuna pozizira. Chofunika kwambiri pa thermoplastics ndi chakuti amatha kusinthidwa, kutenthedwa, kusungunukanso, ndi kukonzanso.

Ngakhale ma polima a thermoplastic amapereka zabwino monga kulimba kwamphamvu, kusinthasintha, luso lokonzanso, komanso kukana mankhwala, amakhalanso ndi zovuta monga kufewetsa ndi kusungunula pa kutentha kochepa.

2. Thermosets

Kusiyana kwakukulu pakati pa ma polima a thermoset ndi thermoplastic ndi momwe amachitira ndi kutentha. Ma polima a thermoplastic amafewetsa ndi kutentha ndikusintha kukhala mawonekedwe amadzimadzi. Njira yochiritsa ndiyo yosinthika, kutanthauza kuti ikhoza kupangidwanso ndikusinthidwanso. Ikayikidwa mu nkhungu ndi kutenthedwa, thermoset imalimba ku mawonekedwe otchulidwa, koma ndondomeko yolimbayi imaphatikizapo kupanga zomangira zenizeni zomwe zimatchedwa cross-links, zomwe zimagwira mamolekyu m'malo ndikusintha chikhalidwe choyambirira cha zinthu.

Mwa kuyankhula kwina, ma polima a thermoset ali ndi mawonekedwe omwe amawalepheretsa kusungunuka ndi kukonzanso pamene akuchiritsa. Akachiritsa, amasunga mawonekedwe awo kutentha ndikukhala olimba. Ma polima a thermosetting amalimbana ndi kutentha kwambiri, amakhala okhazikika, ndipo sangathe kusinthidwanso kapena kuwongoleredwa.

Magawo Ogwiritsa Ntchito Polima

Zinthu zambiri zopangidwa ndi organic, kuphatikiza mapulasitiki, mphira, zomatira, zomatira, thovu, utoto, ndi zosindikizira, zimatengera ma polima. Zomwe zimagwiritsidwa ntchito kwambiri polima pomanga zimaphatikizapo utoto, zotchingira madzi, zotsekera, zokutira ndi zokutira pansi, ndi mitundu yonse yazinthu zomwe tingaganizire.

Ndi chitukuko cha masauzande a ma polima pamsika m'malo a labotale, zinthu zomwe zimagwiritsidwa ntchito popanga zatsopano nthawi zonse zimatuluka. Ma polima, omwe amapezeka pafupifupi pafupifupi chilichonse m'nyumba, amagwira ntchito kwambiri poletsa madzi. Zida zotchingira polima, zomwe zitha kuyikidwa pamalo osiyanasiyana monga konkriti, chitsulo, aluminiyamu, matabwa, ndi phula zovundikira, zimasunga magwiridwe antchito ngakhale kutentha kochepa, komanso kukhala ndi asidi wambiri komanso kukana kwapansi, ndi zina mwazofunikira. za ntchito zomanga.
