Ma polima awa amagwira ntchito yofunika kwambiri pa moyo watsiku ndi tsiku ndipo amagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana a mafakitale, mankhwala, ndi thanzi. Zitsanzo zodziwika bwino za ma polima achilengedwe ndi monga cellulose, mapuloteni, rabara wachilengedwe, ndi... Werengani zambiri
Zitsanzo za Mavuto Okhudza Kuwonongeka kwa Pulasitiki: Pulasitiki ndi chimodzi mwa zinthu zomwe zimagwiritsidwa ntchito kwambiri masiku ano. Kuyambira pakulongedza chakudya mpaka zida zapakhomo, pulasitiki imapereka maubwino osiyanasiyana, kuphatikizapo kukhala yopepuka, yolimba, komanso yotsika mtengo. Komabe, chimodzi mwa mavuto akuluakulu okhudzana ndi pulasitiki ndi kuwonongeka kwake. Kulephera kwa mitundu yambiri ya pulasitiki kuwonongeka mwachilengedwe... Werengani zambiri
Zitsanzo za Mafunso Okambirana: Zitsanzo za Pulasitiki Pulasitiki ndi chimodzi mwa zinthu zomwe zimagwiritsidwa ntchito kwambiri tsiku ndi tsiku. Chimagwiritsidwa ntchito m'njira zosiyanasiyana, kuyambira pakulongedza chakudya mpaka zida zamagalimoto. Munkhaniyi, tikambirana mafunso okambirana za mitundu yosiyanasiyana ya pulasitiki, makhalidwe awo, ndi momwe amagwiritsidwira ntchito nthawi zambiri m'moyo watsiku ndi tsiku. Kodi Pulasitiki ndi Chiyani? Pulasitiki… Werengani zambiri
Chitsanzo cha Mafunso Okambirana za Mapulasitiki: Kufufuza Ubwino ndi Zotsatira za Zinthu Zodziwika Kwambiri. Pulasitiki, imodzi mwa zipangizo zodziwika bwino m'miyoyo yathu ya tsiku ndi tsiku, yabweretsa zabwino zambiri, komanso yabweretsa mavuto ambiri okhudzana ndi chilengedwe. M'nkhaniyi, tifufuza mozama za pulasitiki, kumvetsetsa ubwino wake, kuwunikanso mavuto okhudza chilengedwe omwe akukumana nawo, ndikufufuza lingaliro la... Werengani zambiri
Zitsanzo za Mafunso Okhudza Ubale Pakati pa Kapangidwe ndi Makhalidwe a Ma Polima Chiyambi Ma polima ndi zinthu zapadera zopangidwa ndi maunyolo ataliatali, obwerezabwereza a mamolekyu otchedwa ma monomers. Kapangidwe ka ma polima kamasiyana kwambiri, ndipo kusiyana kumeneku kumakhudza mwachindunji mawonekedwe awo enieni. Kumvetsetsa momwe kapangidwe ka ma polima kamakhudzira mawonekedwe awo ndikofunikira kwambiri pakugwiritsa ntchito ukadaulo ndi mafakitale osiyanasiyana. Nkhani… Werengani zambiri
Zitsanzo za Mafunso ndi Kukambirana za Mitundu ya Ma Polima Polima ndi molekyulu yayikulu yopangidwa ndi mayunitsi ang'onoang'ono otchedwa ma monomers. Ma polima amagwiritsidwa ntchito m'njira zosiyanasiyana, kuyambira pulasitiki ndi rabara mpaka ulusi wopangidwa ndi zinthu zomangira. Kumvetsetsa ma polima ndikofunikira kwambiri mu chemistry, sayansi ya zinthu, ndi mafakitale osiyanasiyana. Nkhaniyi ikambirana zina mwa... Werengani zambiri
Zitsanzo za Mafunso ndi Kukambirana pa Kupopera kwa Madzi Kupopera kwa madzi ndi mtundu wa polymerization reaction yomwe imapanga ma polima polumikiza ma monomers kudzera mu kuchotsa mamolekyu ang'onoang'ono, monga madzi, methanol, kapena HCl. Njirayi imagwira ntchito yofunika kwambiri pakupanga zinthu zosiyanasiyana za polima zomwe zimagwiritsidwa ntchito tsiku ndi tsiku. Munkhaniyi, tifufuza mafunso achitsanzo ndikukambirana...

Zitsanzo za Mavuto Kukambirana za Kuwonjezera Polima. Polymerization ndi njira yomwe ma monomers—mamolekyu ang'onoang'ono okhala ndi kapangidwe kofanana—amaphatikizika kuti apange mamolekyu akuluakulu otchedwa ma polima. Pali mitundu iwiri ikuluikulu ya polymerization: kuwonjezera polymerization ndi condensation polymerization. Nkhaniyi ikambirana za mtundu umodzi mwa mitundu iyi, kuwonjezera polymerization, ndi kutsindika pa mavuto a zitsanzo ndi kukambirana za... Werengani zambiri
Chitsanzo cha Kuyankha kwa Polymerization Mafunso ndi Kukambirana Kuyankha kwa Polymerization ndi nkhani yofunika kwambiri mu organic chemistry. Njirayi imaphatikizapo kuphatikiza mamolekyulu a monomer kukhala mamolekyulu akuluakulu otchedwa ma polima. Ma polima ndi ofunikira pa moyo watsiku ndi tsiku, kuyambira zipangizo zopangira mapulasitiki ndi rabara mpaka ulusi wa nsalu.
