Imathiriyeli ekrwada: i-polyamide, i-polypropylene kunye ne-polyester.Intambo nganye yenziwe nge-ultra-thin filaments.Oku kulandelayo sisingeniso kwiifiber eziphambili esizisebenzisayo kunye neempawu zazo.
Izinto ezisetyenziswa rhoqo
I-Polyamide yeyona fiber isetyenziswa kakhulu, esetyenziselwa ukwenza iintambo ezikumgangatho ophezulu kwizinto ezenziweyo.Ezona ndidi ziqhelekileyo zepolyamide yiDuPont inayiloni (PA 6.6) kunye nePerlon(PA 6).I-Polyamide ayinxibi, yomelele kakhulu kwaye iyalastiki kakhulu.Iyakwazi ukufudumeza kwaye imise ngokusisigxina-esi sixhobo sisetyenziswe kwinkqubo yokulungisa ubushushu.Ngenxa yesidingo sokufunxa amandla, intambo yamandla yenziwe ngokupheleleyo ngepolyamide.Ifayibha yePolyamide ikwasetyenziswa ngokubanzi ukwenza iintambo ezimileyo, nangona uhlobo lwemathiriyeli enokwandiswa okuncinci lukhethiwe.Ububi bepolyamide kukuba ifunxa amanzi amaninzi, nto leyo eya kubangela ukuba inciphe ukuba iba manzi.
Ngenxa yokuba i-polypropylene, ilula kakhulu ubunzima.
I-Polypropylene ilula kwaye iphantsi.Ngenxa yokunganyangeki kwayo okuphantsi, i-polypropylene isetyenziswa kakhulu ukwenza iintsimbi zentambo, ezikhuselwe ngeeshethi ze-polyamide.I-Polypropylene ilula kakhulu ngobunzima, iphantsi koxinaniso kwaye inokudada.Yiyo loo nto siyisebenzisa ukwenza intambo yomsinga wethu.
Ukusetyenziswa kwepolyester
Iintambo ezimileyo ezenziwe ngeentsinga zepolyester zisetyenziswa ikakhulu kwimisebenzi enokudibana neeasidi okanye iikhemikhali ezonakalisayo.Ngokungafaniyo ne-polyamide, inokumelana ne-asidi ephezulu kwaye ayifunxa nzima amanzi.Nangona kunjalo, i-polyester fiber ineempawu ezilinganiselweyo zokufunxa amandla, okuthetha ukuba ukusetyenziswa kwayo kwi-PPE kulinganiselwe.
Ukufumana amandla aphezulu eenyembezi.
Intambo yeDynema I-Dynema yintambo yokwenziwa kwefiber eyenziwe nge-ultra-high molecular weight polyethylene.Inamandla aphezulu kakhulu okukrazula kunye nobude obuphantsi kakhulu.Ukubalwa ngomlinganiselo wobunzima, amandla ayo okuqina ngama-15 amaxesha entsimbi.Iimpawu zayo eziphambili kukuxhatshazwa okuphezulu, ukuzinza okuphezulu kwe-ultraviolet kunye nobunzima bokukhanya.Nangona kunjalo, intambo ye-Dyneema ayiboneleli nayiphi na i-absorption yamandla ashukumisayo, eyenza ingafaneleki kwizixhobo zokukhusela zomntu.Intambo yeDyneema isetyenziswa ikakhulu ukutsala izinto ezinzima.Zidla ngokusetyenziswa endaweni yeentambo zentsimbi ezinzima.Ngokwenza umsebenzi, indawo yokunyibilika kwentambo yeDyneema iphantsi kakhulu.Oku kuthetha ukuba iintsinga ze-Dynema intambo ye-Dynema (intambo ephezulu yobunzima bemolekyuli ye-polyethylene) inokonakala xa ubushushu bungaphezu kwe-135 degrees celcius.
Ukutolikwa okugqibeleleyo kokumelana nokusika.
I-Aramid yomelele kakhulu kwaye i-fiber-resistant-resistant fiber kunye nokumelana nokusika okuphezulu.Njengentambo ye-Dyneema, intambo ye-aramid ayiboneleli ngokufunxa ngamandla, ngoko ke ukusebenza kwayo kwi-PPE kulinganiselwe.Ngenxa yobuntununtunu obugqithisileyo bokugoba kunye nokunganyangeki kwe-ultraviolet, iifiber ze-aramid zihlala zinikwa i-polyamide sheaths ukuzikhusela.Sisebenzisa intambo ye-aramid ukuze sisebenze kwintambo yesistim yokubeka umsebenzi, efuna ukwandiswa okuncinci kunye nokumelana nokusika okuphezulu.
