Kodi polima ndi chiyani ndi limodzi mwa mafunso omwe anthu ambiri amafunsa kawirikawiri okhudza mankhwala omangira. Polima, yomwe imapezeka kwambiri mu zipangizo zomangira, imapezekanso mu kapangidwe ka zinthu zambiri zomwe zimagwiritsidwa ntchito tsiku ndi tsiku. Polima, yomwe ili ndi mitundu iwiri yosiyana monga yachilengedwe ndi yopangidwa, imapezekanso mu DNA yathu.

MongaBaumerk, katswiri wa mankhwala omanga, tidzayankha funso lakuti polima ndi chiyani m'nkhani yathu, komanso kufotokoza madera ake ogwiritsira ntchito ndi momwe amagwiritsidwira ntchito. Mukawerenga nkhani yathu, mudzatha kumvetsetsa zomwe polima, yomwe imapezeka muzinthu zambiri zomwe zimagwiritsidwa ntchito pomanga, imathandizira pa zomangamanga.

Kuti mudziwe zambiri zokhudza mastic, chinthu china chomangira chomwe chimagwiritsidwa ntchito kwambiri, mutha kuwerenga nkhani yathu yotchedwa mastic.Kodi Mastic ndi chiyani? Kodi Mastic imagwiritsidwa ntchito kuti?

Kodi polima ndi chiyani?

Yankho la funso lakuti tanthauzo la polima ndi chiyani 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 mumakampani opanga mankhwala omangira. Ndipotu, polima imaphatikizapo zinthu zosiyanasiyana zomwe zimakhala ndi makhalidwe osiyanasiyana. Zimapezeka m'zinthu zambiri zapakhomo zomwe zimagwiritsidwa ntchito tsiku ndi tsiku, zovala, zoseweretsa, komanso chofunika kwambiri mu zipangizo zomangira zomwe zimagwiritsidwa ntchito poteteza kutentha.

Polima ndi mankhwala omwe mamolekyu ake amalumikizidwa pamodzi mu unyolo wautali, wobwerezabwereza. Chifukwa cha kapangidwe kake, ma polima ali ndi mawonekedwe apadera omwe amatha kusinthidwa kuti agwiritsidwe ntchito mosiyanasiyana. Ma polima amagawidwa m'mitundu iwiri: yachilengedwe ndi yopangidwa. Mwachitsanzo, mphira ndi chinthu chachilengedwe cha polima chomwe chakhala chikugwiritsidwa ntchito kwa zaka zikwi zambiri. Chili ndi mawonekedwe abwino kwambiri otanuka chifukwa cha unyolo wa polima wa mamolekyu womwe umapangidwa ndi chilengedwe.

Polima yachilengedwe yomwe imapezeka kwambiri padziko lonse lapansi ndi cellulose, chinthu chachilengedwe chomwe chimapezeka m'makoma a maselo a zomera. Cellulose nthawi zambiri imagwiritsidwa ntchito popanga zinthu monga mapepala ndi nsalu. Ma polima opangidwa ndi anthu kapena opangidwa ndi anthu amaphatikizapo zinthu mongapolyethylenendi polystyrene, mapulasitiki odziwika kwambiri padziko lonse lapansi, omwe amapezeka m'zinthu zambiri. Ma polima ena opangidwa ndi zinthu amatha kupindika, pomwe ena amakhala olimba nthawi zonse.

Kodi makhalidwe a ma polima ndi ati?

Kagwiridwe ka ntchito ka zinthu zomwe zimawonjezera kulimba pantchito zomanga nyumba n'kofunika kwambiri. Zigawo za mankhwala omwe amawonjezera moyo wa nyumba ndikupangitsa malo okhala kukhala omasuka ziyeneranso kukhala pamlingo wokwanira. Chifukwa chake, zinthu za polima zimasiyana kwambiri ndi zinthu zosiyanasiyana. Ma polima omwe angapangidwe m'malo opangira mankhwala amatha kukhala ndi zinthu zomwe akufuna kutengera dera lomwe akugwiritsidwa ntchito.

Chifukwa cha zinthu zimenezi, ma polima amakhala olimba ku mphamvu zomwe zingachitike akagwiritsidwa ntchito ndipo amakhala pakati pa njira zoyenera kwambiri zopangira mankhwala omangira. Chifukwa chake, zipangizo zomangira zopangidwa ndi polima zomwe sizimakhudzidwa ndi madzi ndi mankhwala ndizodziwika kwambiri.

Kodi Mitundu ya Ma polima ndi Chiyani?

Kuwonjezera pa mafunso okhudza kuti polima ndi chiyani komanso makhalidwe ake ndi ati, nkhani ina yofunika kuyankhidwa ndi yakuti mitundu ya ma polima yomwe ilipo pamsika ndi iti. Ma polima amagawidwa m'magulu awiri akuluakulu: ma thermoplastics, ndi ma thermosets. Chinthu chofunika kwambiri chomwe chimapangitsa kusiyana pakati pa mitundu iyi ya ma polima ndi momwe amachitira akakumana ndi kutentha.

1. Thermoplastics

Ma thermoplastics ndi utomoni womwe umakhala wolimba kutentha kwa chipinda koma umakhala pulasitiki komanso wofewa ukatenthedwa. Pambuyo pokonzedwa, nthawi zambiri poika jekeseni kapena kupopera, ma thermoplastics amatenga mawonekedwe a nkhungu momwe amathiridwa ngati kusungunuka ndikukhazikika mu mawonekedwe omwe akufuna mwa kuziziritsa. Chofunika kwambiri pa ma thermoplastics ndichakuti amatha kusinthidwa, kutenthedwanso, kusungunukanso, ndikusinthidwa mawonekedwe.

Ngakhale ma polima a thermoplastic amapereka zabwino monga mphamvu yogwira ntchito kwambiri, kusinthasintha, kuthekera kosintha mawonekedwe, komanso kukana mankhwala, alinso ndi zovuta monga kufewetsa ndi kusungunuka kutentha kochepa.

2. Ma Thermoseti

Kusiyana kwakukulu pakati pa ma polima a thermoset ndi thermoplastic ndi momwe amachitira ndi kutentha. Ma polima a thermoplastic amafewa ndi kutentha ndipo amasanduka mawonekedwe amadzimadzi. Chifukwa chake, njira yophikira imatha kusinthidwa, zomwe zikutanthauza kuti imatha kupangidwanso ndikubwezeretsedwanso. Ikayikidwa mu nkhungu ndikutenthedwa, thermoset imakhazikika ku mawonekedwe omwe atchulidwa, koma njira yolimbitsirayi imaphatikizapo kupanga ma bond enaake otchedwa cross-links, omwe amasunga mamolekyu pamalo ake ndikusintha mtundu woyambira wa zinthuzo.

Mwa kuyankhula kwina, ma polima a thermoset ali ndi kapangidwe kamene kamawaletsa kusungunuka ndi kupangidwanso akamazizira. Akazizira, amasunga mawonekedwe awo kutentha ndipo amakhalabe olimba. Ma polima a thermosetting amapirira kutentha kwambiri, amakhala ndi kukhazikika kwa mawonekedwe, ndipo sangasinthidwe kapena kuwongoledwa.

Malo Ogwiritsira Ntchito Polima

Zipangizo zambiri zopangidwa ndi zinthu zachilengedwe, kuphatikizapo mapulasitiki, ma rabala, zomatira, zomatira, thovu, utoto, ndi zomatira, zimachokera ku ma polima. Ntchito zodziwika kwambiri za ma polima pomanga ndi monga utoto, nembanemba zoteteza madzi, zomatira, zokutira denga ndi pansi, ndi mitundu yonse ya zipangizo zomwe tingaganizire.

Popeza ma polima ambirimbiri akugulitsidwa pamsika m'malo ochitira kafukufuku, zinthu zomwe zimagwiritsidwa ntchito popanga zinthu zatsopano zikutuluka nthawi zonse. Ma polima, omwe amapezeka pafupifupi pazinthu zonse m'nyumba, ndi othandiza kwambiri poteteza madzi. Zipangizo zotetezera kutentha zochokera ku polima, zomwe zingagwiritsidwe ntchito pamalo osiyanasiyana monga konkire, chitsulo, aluminiyamu, matabwa, ndi zophimba za bitumen, zimasunga magwiridwe antchito awo ngakhale kutentha kochepa, ndipo zimakhala ndi asidi wambiri ndi kukana maziko, ndi zina mwa zinthu zofunika kwambiri pa ntchito zomanga.

Kodi Mungagwiritsire Ntchito Bwanji Zipangizo Zotetezera Zochokera ku Polima?

Zipangizo zotetezera kutentha zopangidwa ndi polima zimaperekedwa ndi Baumerk m'mitundu yosiyanasiyana. Kugwiritsa ntchito zipangizo zomwe zimaperekedwa ngati chivundikiro ndi madzi kumachitikanso mosiyana.
