Monga chinthu chofunikira, zida za polima zatenga gawo lalikulu m'mafakitale osiyanasiyana patatha pafupifupi theka lazaka zachitukuko.
The polima zipangizo makampani osati kupereka chiwerengero chachikulu cha zinthu zatsopano ndi zipangizo kwa mafakitale ndi ulimi kupanga ndi zovala za anthu, chakudya, nyumba ndi zoyendera, komanso kupereka kwambiri ndi ogwira mkulu-ntchito structural ndi zinchito zipangizo chitukuko. zaukadaulo wapamwamba.
Zipangizo zogwirira ntchito za polima ndi njira yomwe ikubwera yomwe imaphatikizapo maphunziro osiyanasiyana, kuphatikiza organic chemistry, inorganic chemistry, optics, magetsi, chemistry, biochemistry, zamagetsi, zamankhwala ndi maphunziro ena ambiri, ndipo ndi gawo lofufuzira lapadera kunyumba ndi kunja. .Chifukwa chachikulu chomwe zida zogwirira ntchito za polima zakhala malo ofunikira kwambiri pakufufuza pazinthu zapanyumba ndi kunja ndikuti ali ndi "ntchito" zapadera zomwe zingagwiritsidwe ntchito m'malo mwa zida zina zogwirira ntchito ndikuwongolera kapena kukonza magwiridwe antchito awo, kuzipanga kukhala zida zogwirira ntchito kwathunthu. katundu watsopano.
Chimodzi ndi cha ziwalo zopangira, monga ma valve a mtima, impso zopangira, khungu lopangira, zotupa za hernia, ndi zina zotero. Chachiwiri ndi zipangizo zachipatala, monga ma catheter opangira opaleshoni, zida zowunikira, zipangizo zoyikira, ndi zina zotero. Chachitatu, amagwiritsidwa ntchito pa mankhwala zowonjezera monga chonyamulira chowongolera mankhwala, zowongolera, ndi zina.
Monga zida zoyambirira, zogwiritsidwa ntchito kwambiri komanso zazikulu kwambiri muzachilengedwe, ma biopolymers ndi gawo lomwe likukula mwachangu, ndipo lakhala gawo lalikulu la zida zamakono zamankhwala, chifukwa chamitundu yosiyanasiyana yazinthu zopangira, kuthekera kosintha mawonekedwe awo kudzera pamapangidwe a maselo. , high bioactivity ndi zinthu zosiyanasiyana.Amagwiritsidwa ntchito makamaka m'malo otsatirawa:
Kugwiritsa ntchito zinthu za polima pochiza madzi
Polima nembanemba zipangizo kuthandiza madzi mankhwala ukadaulo polima zipangizo m'munda wa zopezera madzi Ntchito yofunika m'munda wa madzi ndi nembanemba madzi mankhwala luso.Kuchiza kwa madzi a Membrane Ukadaulo wamankhwala amadzi a Membrane ndi njira yabwino yoyeretsera zimbudzi ndi kukonzanso zinthu zamadzi, ndikuchita bwino kwambiri kulekanitsa, kutsika kwamphamvu kwamphamvu, kutsika pang'ono, njira yosavuta, yosavuta kugwiritsa ntchito komanso yopanda kuipitsa.Amadziwika ndi kulekanitsa kwakukulu, kugwiritsa ntchito mphamvu zochepa, kutsika pang'ono, njira yosavuta, ntchito yosavuta komanso yopanda kuipitsa.
Zida zopangira ma polima mumakampani a waya ndi chingwe
Amagwiritsidwa ntchito ngati chishango cha semi-conductive pazingwe zamagetsi kuti apititse patsogolo kugawa kwamagetsi;zingwe zamagetsi ndi chingwe chamagetsi chodutsa pansi ndikudutsa mchimake chakunja cha nthaka;Kutentha kodziyimira pawokha chingwe chopangira theka-kuyendetsa Pakatikati pa zingwe zowotchera zodzilamulira zokha, ndi zina. Zishango zina zopangira ma semi-conducting nthawi zambiri zimagwiritsidwa ntchito polumikizira chingwe ndi kutha.magetsi kudziona zomatira tepi, chingwe Integrated wosanjikiza madzi wosanjikiza theka-kuchititsa kukana madzi tepi, etc. angathenso wa gulu monga zipangizo polima conductive.
