Iityhubhu zenayiloni,{0}}ukusebenza kweplastiki ityhubhu ephezulu esetyenziswa kakhulu kwimizi-mveliso yeemoto, koomatshini, nakumashishini ekhemikhali, zinenkqubo yokwenziwa kobungqongqo nobuchwephesha obunefuthe ngqo kubulunga kunye nokusebenza kwemveliso. Ukuveliswa kweetyhubhu zenylon ikakhulu kubandakanya amanyathelo aphambili afana nokulungiswa kwezinto eziluhlaza, ukubunjwa kwe-extrusion, ukupholisa kunye nokubunjwa, ukusika i-traction, kunye nokuhlola kunye nokupakishwa. Inqanaba ngalinye lifuna ulawulo oluqinileyo ukuqinisekisa ukuba imveliso egqityiweyo ihlangabezana nemigangatho.
Ukulungiswa kwezinto ezikrwada linyathelo lokuqala kwimveliso. Iibhubhu ze-nylon ngokuqhelekileyo zisebenzisa i-PA6 (i-Nylon 6) okanye i-PA66 (i-Nylon 66) njengeyona nto iphambili, kunye ne-plasticizers, i-stabilizers, okanye i-flame retardants ezongeziweyo ngokweemfuno zesicelo. Izinto eziluhlaza kufuneka zomiswe ukususa umswakama, ukuthintela amaqamza omoya okanye ukuthotywa ngexesha lokukhupha kunye nokuqinisekisa ukuhamba kwezinto kunye nokuzinza.
Ukubumba i-Extrusion yinkqubo engundoqo. Izinto eziluhlaza ezomileyo ziyafudunyezwa kwaye zinyibilike usebenzisa i-screw extruder. Ngaphantsi kweqondo lokushisa eliphezulu (ngokuqhelekileyo i-240-280 degree) kunye noxinzelelo, i-melt iqhutywe kwi-die. Uyilo lokufa luchaphazela ngokuthe ngqo ukuchaneka kwedayamitha yangaphandle yombhobho, ubukhulu bodonga, kunye nobubanzi bangaphakathi; ke ngoko, kufuneka ilungiswe ngokuchanekileyo ngokweenkcukacha. Inayiloni enyibilikisiweyo yenza ulwakhiwo lwe-tubular oluqhubekayo kumngundo kwaye emva koko ingene kwinkqubo yokupholisa.
Ukupholisa kunye nokumila kufezekiswa ngokusebenzisa amanzi okanye ukupholisa umoya ukuqinisa ngokukhawuleza ubushushu obuphezulu benyibilika. Amatanki okupholisa amanzi yeyona ndlela ixhaphakileyo, kusetyenziswa ulawulo lobushushu bamanzi olunyathelweyo ukuthintela uxinzelelo lwangaphakathi olubangelwa kukupholisa ngokukhawuleza, okunokuchaphazela iimpawu zoomatshini. Ityhubhu enayiloni epholileyo kufuneka igcine imilinganiselo ezinzileyo ukuze ibeke isiseko sokusetyenzwa okulandelayo.
Kwinqanaba lokutsala kunye nokusika, ityhubhu ikhutshwe ngesantya esiqhubekayo ngumatshini wokutsala ukuqinisekisa ubude obufanayo. Amandla okutsala kufuneka ahambelane nesantya se-extrusion ukukhusela i-deformation okanye ukuphuka. Emva koko, ityhubhu isikwe ngokuchanekileyo kubude obumiselweyo ngumatshini wokusika, ifuna i-burr egudileyo,{2}}isikiwe sasimahla.
Ekugqibeleni, imveliso egqityiweyo ihlolwa ngokungqongqo, kubandakanywa nokuhlolwa okubonakalayo (ubunono, akukho maqamza), umlinganiselo we-dimensional (ububanzi bangaphandle, ukunyamezela kobunzima bodonga), kunye novavanyo lokusebenza (ukumelana noxinzelelo, ukuxhathisa i-abrasion, ukuxhathisa imichiza). Iimveliso ezifanelekileyo zipakishwa kwaye zigcinwe ukuqinisekisa ukuba azonakaliswa ngexesha lokuthutha.
Inkqubo yokuveliswa kweetyhubhu zenylon idibanisa isayensi yezinto, ubunjineli boomatshini, kunye neteknoloji yokulawula umgangatho. Ulawulo olucokisekileyo lwenyathelo ngalinye lungundoqo ekuqinisekiseni ukusebenza kwalo okuphezulu kunye nobomi obude.
