Ipholiyesta. Yintoni na le nto, yaye yintoni na ukusetyenziswa kwayo

Ngaloo mihla, xa ipholima ezahlukeneyo kunye zeplastiki sele ngenkuthalo yaphunyezwa kubomi bemihla ngemihla, abantu bacinga ukuba ngoncedo lwabo banokucombulula phantse zonke iingxaki, ezininzi kakhulu izinto zendalo. Le Sisenokulila lwenzululwazi-technical nemichiza ngangosuku ukuba novalo emva yoma, de uluntu ukuqinisekisa ukuba umqhaphu, nelinen okanye zewulu impahla nangoku kwiimeko ezininzi ngaphezu naliphi zokwenziwa. Noko ke, ezo engamashumi ezazingekho ilize, iimpawu ezininzi ezibalulekileyo kakhulu luncedo of Iipholima wadala iimeko isicelo wazo kwiinkalo ezahlukeneyo zezinto ezenziwa luluntu.

Omnye umbandela iqhelekileyo synthetic yi ipholiyesta. Yintoni na le mveliso ukwenziwa kweemveliso ezithile isetyenziswa ngoku? Ukuphendula le mibuzo, kufuneka kuqala siqonde iimpawu yemichiza mechanical le Polymer.

Njengoko ebonakalayo ipholiyesta multimolecular polyether chain. Xa Yindibanisela Polymer ukuba obusenyongweni, ezenza yomelele kakhulu. Xa isicelo impahla oku kuthetha ukuxhathisa yalo phezulu ukuba ndiyaqwenga ndezela. Ingaba le okulungileyo? Kakade ke, ukuba ezinye zezi mpawu ezo manqaku yangasese kubalulekile, kwakunye nokukwazi ukumelana ukufuma. Kodwa yonke into embi. ukufakwa kwamanzi ephantsi ukuqina kwezinto kwenza kube andiyithandi ngokunxulumene kumphezulu esikhumbeni. Kodwa vulavula hi ipholiyesta ukuba ngokupheleleyo ilaphu ezingafanelekanga ezingubeni, awukwazi nje yayo anqongophele.

Amazwe athile amagama zorhwebo ezahlukeneyo, nto leyo ebizwa ipholiyesta. Ukwakhiwa izinto raw inokudityaniswa, umzekelo, "65% uboya,-35% ipholiyesta." Buthi, Ilizwi eli, xa uqala kuqala, amazwe, enyanisweni, kuyinto segama, apho Academy of Sciences - Academy of Sciences, kwaye oonobumba "L", "A" kwaye "B" ithetha kwilebhu iikhompawundi ophezulu-eziphilayo. Kwi-US, le nto iveliswa phantsi kwegama "Dacron".

Kwezobugcisa, le Polymer lisetyenziswa ngenxa ngokweempawu ezizodwa. Umzekelo, ukuba imveliso nezinto zokubopha ezifuna amandla aphezulu, ipholiyesta ebanzi ezisetyenzisiweyo. Ziziphi ezi mpawu? Iyahlala for retaining amabhali ezweni ukuba kakhulu nokolula amandla compressive kuphela nokumelana obuphantsi kancinane yeyokuchitha zephetshana yesinyithi, apho Polymer kulula kakhulu, kwaye kubalulekileyo, ngaphantsi yentsimbi. zixhobo amandla ipholiyesta ibangela izicelo zabo kwiimeko apho umthungo kufuneka oluthembekileyo kakhulu, neentambo, ephothiweyo kubo, unako ukumelana imithwalo emikhulu.

Kwizithuthi kushishino moya kunye nolwakhiwo jikelele eminyaka yokugqibela sele ngokubonakalayo ukwandisa umda lwesicelo izinto zizonke polymeric. Nayiphi na into, ukuba olusetyenziswa endaweni mveliso zeplastiki dural, kunciphisa ubunzima yaye kuphucula nokumelana. lweenqwelo Military, le ipholiyesta inomnye ipropati ebalulekileyo: abaphandi bafumanisa ngokuhlolisisa ipholiyesta, oko izinto radioprovodyaschy. Lo mhlaba likuvumela ukuba wenze evela radomes bakhe radar kanye moya silhouette libonakala kangako utshaba umoya wokhuselo kunokwenzeka.
