Kutheni sikhetha ilaphu le-nylon?
I-nylon yifayibha yokuqala yokwenziwa eyavela ehlabathini. Ukwenziwa kwayo luphumo olukhulu kwishishini lefayibha yokwenziwa kwaye linyathelo elibaluleke kakhulu kwikhemistri yepolymer.
Zithini iingenelo zelaphu le-nylon?
1. Ukumelana nokuguguleka. Ukumelana nokuguguleka kwe-nylon kuphezulu kunokwezinye iifayibha, kuphindwe kalishumi kunekotoni kwaye kuphindwe kangama-20 kuneboya. Ukongeza iifayibha ze-polyamide kwilaphu elixutyiweyo kunokuphucula kakhulu ukumelana nokuguguleka kwayo; xa yoluliwe ukuya kuthi ga kwi-3 Xa -6%, izinga lokubuyisa i-elastic lingafikelela kwi-100%; inokumelana namashumi amawaka amaxesha okugoba ngaphandle kokuqhekeka.
2. ukumelana nobushushu. Njenge-nylon 46, njl., i-nylon ekristale ephezulu inobushushu obuphezulu bokujikajika kobushushu kwaye ingasetyenziswa ixesha elide kwi-150 degrees. Emva kokuba i-PA66 iqiniswe ngeefayibha zeglasi, ubushushu bayo bokujikajika kobushushu bunokufikelela ngaphezulu kwe-250 degrees.
3.ukuxhathisa ukugqwala. I-nylon ixhathisa kakhulu kwi-alkali kunye nolwelo oluninzi lwetyuwa, ikwaxhathisa kwi-acids ezibuthathaka, ioyile yemoto, ipetroli, ii-compounds ezinuka kamnandi kunye nezinyibilikisi ngokubanzi, ayisebenzi kwi-compounds ezinuka kamnandi, kodwa ayixhathisi kwi-acids ezinamandla kunye nee-oxidants. Ingamelana nokukhukuliseka kwepetroli, ioyile, amafutha, utywala, i-alkali ebuthathaka, njl.njl. kwaye inamandla amahle okulwa nokwaluphala.
4.Ukufakwa kwe-insulation. I-nylon inokumelana nomthamo ophezulu kunye ne-voltage ephezulu yokuqhekeka. Kwindawo eyomileyo, ingasetyenziswa njengesixhobo sokukhusela i-frequency yamandla, kwaye isenayo i-insulation yombane efanelekileyo nokuba kwindawo enomswakama ophezulu.
