Izina ry'ibicuruzwa:Polyurethane

Imiterere ya molecular

Imiti yimiti:

Polyurethanes yakoraga mbere kandi akora iperereza na Dr. Otto Bayer mu 1937. Polyurethane ni polymer aho ishami risubiramo ririmo ubwoko bwa Urethane. Urethanes ni ibikomokaho acdamike bibaho muburyo bwa esters [15]. Inyungu nyamukuru ya PU nuko urunigi rudagizwe gusa na atome ya karubone ahubwo ko ari interootoms, ogisijeni, karubone na azote [4]. Kubisabwa byinganda, ibigo bya polyhydroxyl byakoreshwa. Mu buryo nk'ubwo, ibikoresho bya azogeni nyinshi birashobora gukoreshwa mu kunezeza. Muguhindura no guhindura amazonga ya Polyhydroxy na PolyFincturel, Pus itandukanye irashobora gusinya [15]. Polyester cyangwa PolyEt yongeye kuba irimo amatsinda ya hydroxyl akoreshwa mugukora PolyEer Polyether-PU, ukurikirana [6]. Gutandukana mu mubare w'abasimbuye hamwe n'umwanya hagati no mu ngoyi zishami zitanga pus kuva kumurongo wo gutwika kandi 9Bible to Sfatie. Umuseribar у akoreshwa mugukora fibre no kubumba [6]. Ibirungo byoroshye bikoreshwa mugukora abakozi bashinzwe guhambire hamwe na coatings [5]. Guhinduka kandi biteye imbere plastike bimenetse, bigize ubwinshi bwa pus byakozwe, murashobora kuboneka muburyo butandukanye mu nganda [7]. Gukoresha molecular nkeya prepolymers, copolymers zitandukanye zishobora kubyara. Itsinda ryamateka rya terefone ryemerera gusimburana, ryitwa ibice, byinjizwa mumurongo wa PU. Gutandukana muri ibi bice bivamo muburyo butandukanye bwimbaraga za kanseri na elastique. Kureka gutanga icyiciro cya Crystalline kandi kirimo urunigi rwitwa ibice bikomeye [7]. Abatanga icyiciro cya amorphous rubbery kandi birimo polyester / polysether bitwa ibice byoroshye. Ubucuruzi, ibi bice polymers bizwi nka pus yatandukanijwe

Gusaba:

Polyible Polyinethane ahanini ni imiterere yumurongo hamwe nubukungu, bufite imbaraga nziza, kurwanya imiti, kwihangana nubutaka kuruta pvc ifuro. Ifite ubushyuhe bwiza, ubushishozi bwumvikana, kurwanya igituba na kinti-uburozi. Kubwibyo, ikoreshwa mugupakira, kwinjiza amajwi no kuyuzuza ibikoresho. Rigid Polyurethane plastiki ni urumuri, ubwitonzi bwumvikana, insuline nziza cyane, imiti irwanya imiti, imitungo myiza yamashanyarazi, no gutunganya amazi yoroshye. Irakoreshwa cyane muburyo bwo kubaka, ibinyabiziga, inganda zindege, insulation yubushyuhe nubushuhe. Imikorere ya Elanesthane hagati ya plastike na reberi, kurwanya peteroli, kwambara ihohoterwa, kurwanya ubushyuhe, kurwanya ubushyuhe, gukomera, gukomera kwinshi, gukomera kwa kabiri, gukomera kwa kabiri, gukomera kwinshi, gukomera kwa kabiri, gukomera kwa kabiri, gukomera kwa kabiri, gukomera kwinshi, gukomera kwa kabiri, gukomera kwa kabiri, gukomera kwa kabiri, gukomera kwinshi, gukomera kwa kabiri, gukomera kwinshi, gukomera kwinshi. Irakoreshwa cyane mu nganda z'inkweto n'ubuvuzi. Polyurethane nayo irashobora gukorwa mubico, amatwi, uruhu rwa synthique, nibindi
