Polyester. Chii zvinhu ichi, uye chii chiri kushandiswa kwayo

Mumazuva iwayo, kana Polymers siyana uye mapurasitiki vave achishingaira chinozoiswa muupenyu hwezuva nezuva, vanhu vaifunga kuti vane rubatsiro wavo anogona kugadzirisa zvinenge zvose matambudziko, yakawandisa dzinongoitika zvinhu. Izvi nesayenzi-hwokugadzira uye makemikari euphoria kubvira mukupera forties ari manonwe, kusvikira vanhu nechokwadi chokuti donje, wakarukwa kana shinda zvokufuka ichiri muzviitiko dzakawanda kupfuura chero chakaita zvokugadzirwa. Zvisinei, mumakumi emakore iwayo asiri pasina, zhinji inokosha chaizvo uye anobatsira unhu Polymers akasika zvinhu nokuda kwavo kwazvo kushanda muminda mabasa evanhu akasiyana.

Chimwe chezvinhu zvakafanana chakaita zvokugadzirwa zvinhu ndiyo polyester. Chii chigadzirwa ichi kuti pagadzirwe zvimwe zvigadzirwa rinoshandiswa ikozvino? Kuti tipindure mibvunzo iyi, mumwe anofanira kutanga kunzwisisa zvemakemikari uye zvemaziso zvivako zviri polymer.

Sezvo mashoko acho ane polyester multimolecular polyether cheni. Mune kwetunhu polymer ane zvisungo simba, kuiita zvikuru simba. Kana rikashandiswa kune zvipfeko izvi zvinoreva kurwisa kwayo kumusoro kubvarura uye crease. Akanaka uyu? Chokwadi, zvimwe izvi unhu hunokosha chimbudzi nyaya, uyewo kukwanisa kudzivisa unyoro. Asi zvinhu zvose ane marapirwo. Low Absorção de Água uye kuomarara mashoko kuti zvakanaka pachinhu ganda pamusoro. Asi kutaura pamusoro polyester chiri chose jira kukodzera mbatya, haukwanisi ayo zvezvinotaurwa ishoma.

Nyika dzinosiyana zvokutengeserana mazita akasiyana, izvo akasarudzwa Polyester. Zvinoumba mbishi zvinhu anogona zvabatanidzwa Somuenzaniso, "65% shinda, 35% polyester." Shoko iri, panguva Pakutanga, vatorwa, chokwadi, chinhu chidimbu, izvo Academy of Sciences - Academy of Sciences, uye tsamba "L", "A" uye "B" zvinoreva murabhoritari soro-samolecular yeimwe. Mune US, mashoko aya anogadzirwa pasi zita "Dacron".

In zvigadzirwa, polymer izvi zvikuru kushandiswa nokuda inokosha ehupfumi. Somuenzaniso, nokuti kugadzirwa kavha zvinhu yaida yakakwirira simba, yakafara polyester kushandiswa. Ndezvipi hunhu izvi? Mukurumari nokuti tightening strapping Bales vane substantially kuswatura simba compressive ndiyo chete zvishoma muduku nemishonga kuti zvange zviri simbi zviuno, sezvamakaropafadzwa polymer zviri nyore zvikuru uye, pazvese, zvishoma simbi. Simba polyester filaments kunokonzera kushanda kwavo zviitiko apo musono inofanira akavimbika kwazvo, uye tambo, yakarukwa kubva kwavari, angakudzivisai zvikuru zvinorema.

Munguva yose ndege indasitiri uye kuvakwa motokari okupedzisira emakore uyewo achishingaira kuwedzera kukura kwebasa kushanda rinoumba polymeric zvinhu. chinhu chipi, uko rinoshandisirwa pachinzvimbo mukugadzira dural mapurasitiki, kunoderedza uremu uye kunonatsiridza ngura nemishonga. Military avhiyesheni, polyester ichi ine chimwe chinokosha pfuma: vaongorori vakawana nokuongorora polyester, izvozvo radioprovodyaschy zvinhu. pfuma iyi kunoita kuti aite kwake radar radomes uye ndege siluetti rinova zvishoma zvinoonekwa muvengi mhepo kudzivirira zvinobvira.
