YIHOO PA (polyamide) polymerisation & inyongeramusaruro
Polyamide (nanone yitwa PA cyangwa Nylon) nijambo rusange rya resmoplastique resin, irimo amide yisubiramo kumurongo munini wa molekile. PA ikubiyemo alifatique PA, alifatique - impumuro nziza PA na aromatic PA, aho alifatique PA, ikomoka ku mubare wa atome ya karubone muri monomer syntique, ifite ubwoko bwinshi, ubushobozi bwinshi kandi bukoreshwa cyane.
Hamwe na miniaturizasi yimodoka, imikorere myinshi yibikoresho bya elegitoroniki n’amashanyarazi, hamwe no kwihutisha inzira yoroheje y’ibikoresho bya mashini, icyifuzo cya nylon kizaba kinini kandi kinini. Inenge ya Nylon nayo ni ikintu cyingenzi kigabanya imikoreshereze yacyo, cyane cyane kuri PA6 na PA66, ugereranije nubwoko bwa PA46, PA12, bifite inyungu zikomeye, nubwo imikorere imwe idashobora kuzuza ibisabwa byiterambere ryinganda zijyanye nayo.

YIHOO PC (Polyakarubone) inyongera
Polyakarubone (PC) ni polymer irimo itsinda rya karubone mumurongo wa molekile. Ukurikije imiterere yitsinda rya ester, irashobora kugabanywamo alifatique, aromatic, aliphatic - aromatic nubundi bwoko. Ibikoresho bike bya mikoranike ya alifatique na alifatique aromatic polycarbonate igabanya imikoreshereze yabyo muri plastiki yubuhanga. Gusa polikarubone ya aromatic yakozwe munganda. Bitewe numwihariko wimiterere ya polyakarubone, PC yahindutse plastiki rusange yubuhanga hamwe nubwiyongere bwihuse muri plastiki eshanu zubuhanga.
PC ntishobora kwihanganira urumuri ultraviolet, alkali ikomeye, hamwe no gushushanya. Ihinduka umuhondo hamwe nigihe kirekire cyo guhura na ultraviolet. Kubwibyo, gukenera inyongeramusaruro ni ngombwa.

YIHOO Yoroheje ya VOC yimodoka trim inyongera
Mu myaka yashize, hamwe n’ishyirwa mu bikorwa ry’imiterere y’ikirere cy’imodoka, ubuziranenge bw’imodoka hamwe n’urwego rwa VOC (volatile Organic Compound) rwabaye igice cyingenzi mu igenzura ry’imodoka. VOC ni itegeko ryibintu kama, cyane cyane bivuga akazu k’imodoka hamwe n’ibikoresho byo mu mizigo cyangwa ibikoresho by’ibinyabuzima, cyane cyane birimo urukurikirane rwa benzene, aldehydes na ketone na undecane, butyl acetate, phthalate nibindi.
Iyo kwibumbira hamwe kwa VOC mumodoka bigeze kurwego runaka, bizatera ibimenyetso nko kubabara umutwe, isesemi, kuruka numunaniro, ndetse bigatera guhungabana na koma mubihe bikomeye. Bizangiza umwijima, impyiko, ubwonko na nervice sisitemu, bikaviramo kubura kwibuka nizindi ngaruka zikomeye, bikaba bibangamiye ubuzima bwabantu.
