Raw zvinhu: polyamide, polypropylene uye polyester.Tambo imwe neimwe yakagadzirwa ne-ultra-thin filaments.Izvi zvinotevera sumo kune mafibhi makuru atinoshandisa uye maitiro awo.
Zvinowanzoshandiswa zvinhu
Polyamide ndiyo fiber inonyanya kushandiswa, iyo inoshandiswa kugadzira tambo dzemhando yepamusoro kubva kune zvigadzirwa.Mhando dzinonyanyozivikanwa dzepolyamide iDuPont naironi (PA 6.6) nePerlon(PA 6).Polyamide haipfeki, yakasimba kwazvo uye elastic.Inogona kupisa uye kuumbwa zvachose-ichi chimiro chinoshandiswa mukugadzirisa kupisa.Nekuda kwekuda kutora simba, tambo yemagetsi inogadzirwa zvachose ye polyamide.Polyamide faibha inoshandiswawo zvakanyanya kugadzira tambo dzakasimba, kunyangwe rudzi rwezvinhu zvine kuwedzera kushoma kwakasarudzwa.Kuipa kwepolyamide ndeyekuti inotora mvura yakati wandei, izvo zvinozoita kuti itete kana ikanyorova.
Nekuti iri polypropylene, ine huremu hwakanyanya.
Polypropylene yakareruka uye yakachipa.Nekuda kwekushomeka kwayo kwekupfeka, polypropylene inonyanya kushandiswa kugadzira tambo cores, iyo inodzivirirwa ne polyamide sheaths.Polypropylene yakareruka muhuremu, yakaderera mukuwanda uye inogona kuyangarara.Ndiko kusaka tichirishandisa kuita tambo yerukova rwedu.
Kushandisa polyester
Tambo dzakasimba dzakagadzirwa nepolyester fiber dzinonyanya kushandiswa kumabasa anogona kusangana nemaasidhi kana makemikari anoparadza.Kusiyana ne polyamide, ine yakakwira asidhi kuramba uye haitore mvura.Nekudaro, polyester fiber inongova neashoma simba absorption maitiro, zvinoreva kuti kushanda kwayo kuPPE kushoma.
Wana simba rekubvarura rakakwirira.
Dynema tambo Dynema itambo yekugadzira fiber yakagadzirwa ne-ultra-high molecular weight polyethylene.Iine simba rakanyanyisa rekubvarura uye kureba kwakaderera zvakanyanya.Ikaverengerwa nehuremu reshiyo, simba rayo rekusimba rakapetwa ka15 pane resimbi.Mamiriro ayo makuru ndeakakwira kupfeka kuramba, yakakwira ultraviolet kugadzikana uye huremu huremu.Zvisinei, tambo yeDyneema haipe chero simba rekugadzirisa simba, iro rinoita kuti risakodzere midziyo yekudzivirira yega.Dyneema tambo inonyanya kushandiswa kukweva zvinhu zvinorema.Inowanzoshandiswa panzvimbo yetambo dzesimbi dzinorema.Mukuita, nzvimbo yakanyunguduka yeDyneema tambo yakaderera zvikuru.Izvi zvinoreva kuti tambo dzeDynema tambo Dynema (ultra-high molecular weight polyethylene tambo) inogona kukuvara kana tembiricha ikadarika 135 degrees Celsius.
Tsanangudzo yakakwana yekucheka kushorwa.
Aramid is a yakanyanya kusimba uye inodzivirira kupisa fiber ine yakakwirira yekucheka kuramba.Kufanana netambo yeDyneema, tambo yearamid haipi simba rinotora simba, saka kushanda kwayo kuPPE kune zvishoma.Nekuda kwekunzwa kwayo kwakanyanya pakukotama uye kushomeka kwe ultraviolet kuramba, aramid fibers anowanzo kupihwa polyamide sheaths kuti azvidzivirire.Isu tinoshandisa aramid tambo kuita pane system tambo yekumisikidza basa, iyo inoda kushoma extensibility uye yakakwirira yekucheka kuramba.
