Chii chinonzi nylon?Chii chinonzi naironi?
Nylon izita rezita remhuri yemapolymer ekugadzira anoumbwa nemapolyamides (anodzokorora mayunitsi akabatanidzwa neamide link).Nylon is sirika-yakafanana thermoplastic inowanzogadzirwa kubva mupetroleum inogona kunyungudutswa-inogadziriswa kuita fiber, mafirimu, kana maumbirwo.Nylon polymers inogona kusanganiswa neyakasiyana-siyana yekuwedzera kuti uwane akawanda akasiyana ezvivakwa kusiyana.Nylon polymers akawana zvakakosha zvekutengesa zvekushandisa mumucheka uye fiber (zvipfeko, pasi uye kusimbiswa kwerabha), mune zvimiro (zvakaumbwa zvikamu zvemotokari, midziyo yemagetsi, nezvimwewo), uye mumafirimu (kunyanya kurongedza chikafu. Nylon ipolymer, inoumbwa. yeinodzokororwa mayuniti emadiamines uye dicarboxylic acids ane manhamba akasiyana emaatomu ekabhoni.Naironi yakawanda yemazuva ano inogadzirwa kubva kune petrochemical monomers (makemikari ekuvaka anoumba mapolymer), akasanganiswa kuita cheni refu kuburikidza necondensation polymerisation reaction. inotonhodzwa uye mafilaments atambanudzwe kuita shinda yarastiki. Yakadzokororwa Nylon ndiyo imwe nzira yeNylon yakagadzirwa kubva mumarara. Kazhinji, Nylon ine zvinokanganisa zvakanyanya nharaunda. Zvakadaro, vagadziri vechinhu ichi vanotsvaga kubatsira kuderedza mhedzisiro yejira iri pane zvakatipoteredza nekushandisa. recycled base materials.
Nei yakadzokororwa Nylon chinhu chakasimba?
1.Yakagadziriswa nylon i-eco-friendly alternative kune yepakutanga fiber nokuti inodarika nzira yekugadzira tsvina.
2. Nylon yakadzokororwa ine zvikomborero zvakafanana nepolyester yakadzokororwa: Inobvisa tsvina kubva mumarara uye kugadzirwa kwayo kunoshandisa zviwanikwa zvishoma pane virgin nylon (kusanganisira mvura, simba uye fossil fuel).
3. Chikamu chikuru chenaironi yakadzokororwa inogadzirwa inobva mumambure ekare ekuredzesa.Iyi ndiyo mhinduro huru yekutsausa marara kubva mugungwa.Inobvawo kubva kumakapeti enylon, tights, nezvimwe.
4.Kusiyana nenaironi yechinyakare yakagadzirwa kubva kumafuta emafuta emhandara, naironi yakadzokororwa inogadzirwa kubva naironi yatovepo mumarara.Izvi zvinoderedza zvakanyanya kukanganisa kwezvakatipoteredza kwejira (padanho rekutsvaga zvinhu, zvakadaro).
5. Econyl ine kudziya kwepasi rose kwakadzikira zvekusvika pa90% zvishoma kana zvichienzaniswa nenylon yakajairika.Tichicherekedza kuti nhamba haina kusimbiswa yakazvimirira.
6. Mambure ekuredza akaraswa anogona kukuvadza zvipenyu zvemumvura uye anovaka nekufamba kwenguva, naironi yakadzokororwa inoita kuti chinhu ichi chishandiswe zviri nani.
Sei tichisarudza zvakashandiswazve naironi?
1.Kune nylon, panguva yekugadzira, akawanda emakemikari anodiwa anoguma mumvura-iyo inozopedzisira yapukunyuka mumvura pedyo nenzvimbo dzekugadzira.Icho hachisi kunyange chakaipisisa chekukanganisa kwenylon panyika.Diamine asidhi inofanirwa kusanganiswa neadipic asidhi kugadzira naironi.Munguva yekugadzirwa kweadipic acid, huwandu hwakawanda hwenitrous oxide hunoburitswa mumhepo.Iri gasi regreenhouse rinonyatsorongedza sezvo richifungidzirwa kuti rinokuvadza zvakapetwa ka300 kune zvakatipoteredza kupfuura carbon dioxide.Kusiyana nemafibhi echisikigo anoonda kwemakore kana makumi emakore, nylon inotora nguva yakareba-senge, mazana emakore kureba.Ndiko kana ichitoperera mudurunhuru.Kazhinji inongokandwa mugungwa (semambure ehove akaraswa) kana kuti pakupedzisira inowana nzira yayo ikoko.
2.Kusiyana nenaironi yechinyakare yakagadzirwa kubva kumafuta emafuta emhandara, naironi yakadzokororwa inogadzirwa kubva naironi yatovepo mumarara.Izvi zvinoderedza zvakanyanya kukanganisa kwezvakatipoteredza kwejira (padanho rekutsvaga zvinhu, zvakadaro).
3.Mutengo wenaironi yakadzokororwa wakafanana neyenaironi, uye ungangodzikira sezvo unowedzera kufarirwa.
4. Naironi yakadzokororwa yawana certification kubva kuOEKO-TEX Standard 100, inova nechokwadi chekuti imwe nhanho yechepfu haipo muchipfeko chekupedzisira.
5. Mabhegi akagadzirwa kubva kunaironi yakadzokororwa anotaridzika akanaka kwazvo, ane umbozha uye ane mhando yepamusoro.Vatengi vanoda zvinhu izvi.
