Khumbula ukuba “umthengi kuqala, umgangatho ophezulu kuqala”, senza umsebenzi ngokusondeleyo nabathengi bethu kwaye sibabonelela ngababoneleli abanobuchule nabanobuchule.I-Dyneemaintambo, Ukubona ukholelwa! Siyawamkela ngokunyanisekileyo amathuba amatsha aphesheya ukuba aseke unxibelelwano lweenkampani kwaye silindele nokuqinisa unxibelelwano nabo bonke abathengi abasele kudala bekho.
Khumbula ukuba “umthengi kuqala, umgangatho ophezulu kuqala”, senza umsebenzi ngokusondeleyo nabathengi bethu kwaye sibabonelela ngababoneleli abanobuchule nabanobuchule.I-Dyneema, Simisele inkqubo engqongqo yokulawula umgangatho. Sinomgaqo-nkqubo wokubuyisela nokutshintshiselana, kwaye ungatshintshiselana kwiintsuku ezisi-7 emva kokuba ufumane iiwigi ukuba zikwisikhululo esitsha kwaye silungisa iimveliso zethu simahla. Khumbula ukuziva ukhululekile ukunxibelelana nathi ukuze ufumane ulwazi oluthe kratya kwaye siya kukunika uluhlu lwamaxabiso olukhuphisanayo ngelo xesha.

Iimbonakalo

Isetyenziswa kakhulu kwiinethi zokuloba zeplankton, inokubonelela ngokudada okungashukumiyo, kwaye amandla okuthwala umthwalo aphantsi kuneentambo zeKevlar.

Amandla Aphezulu: Ngokusekelwe kubunzima, iDyneema inamandla ngokuphindwe kalishumi elinesihlanu kunentambo yentsimbi.

Ubunzima obuKhawulezayo: Ubungakanani ngokobukhulu, intambo eyenziwe ngeDyneema ikhaphukhaphu ngokuphindwe kasibhozo kunentambo yentsimbi.

Imelana namanzi: I-Dyneema ayithandi amanzi kwaye ayifunxi amanzi, nto leyo ethetha ukuba ihlala ilula xa isebenza kwiimeko ezimanzi.

Iyadada: I-Dyneema ine-Specific Gravity ye-0.97 oko kuthetha ukuba iyadada emanzini (ubunzima obuthile bumlinganiselo wobuninzi. Amanzi ane-SG ye-1, ngoko nantoni na ene-SG<1 iyadada kwaye i-SG>1 ithetha ukuba iya kutshona).

Ukumelana neekhemikhali: I-Dyneema ayisebenzi ngokweekhemikhali, kwaye isebenza kakuhle kwiimeko ezomileyo, ezimanzi, ezinetyuwa nezifumileyo, kunye nezinye iimeko apho kukho iikhemikhali.

Ayimelani ne-UV: IDyneema inokumelana okuhle kakhulu nokuwohloka kwefoto, igcina ukusebenza kwayo xa ivezwa kukukhanya kwe-UV. Amandla Aphezulu: Ngokusekwe kubunzima, iDyneema inamandla ngokuphindwe ka-15 kunocingo lwentsimbi.

Iimpawu zomzimba zeefayibha ze-polyethylene ezinamandla aphezulu kunye ne-modulus ephezulu zibalasele kakhulu. Ngenxa yokuba i-crystallinity yayo ephezulu, liqela leekhemikhali elingelula ukuliphendula ngee-arhente zeekhemikhali. Ke ngoko, ayimelani namanzi, umswakama, ukugqwala kweekhemikhali, kunye nemisebe ye-ultraviolet, ngoko ke akukho mfuneko yokuba inyangwe ngonyango lokumelana ne-ultraviolet. Ukumelana nokugqwala, ukumelana ne-asidi kunye ne-alkali, ukumelana nokugqwala okugqwesileyo, ayinayo nje kuphela i-modulus ephezulu, kodwa ikwathambile, inobomi obude bokuguquguquka, indawo yokunyibilika kwefayibha ye-polyethylene enamandla aphezulu iphakathi kwe-144 ~ 152C, ivezwe kwindawo engqongileyo ye-110C ixesha elifutshane ayizukubangela ukuwohloka okukhulu kokusebenza, njl.

Ipharamitha yoBugcisa

Iintambo zeDyneema zenziwe ngeentambo zepolyethylene ezinamandla aphezulu zeDyneema, zize ziqiniswe ngenkqubo yomzimba wentambo ukwenza intambo egudileyo nethambileyo. Into yokuthambisa yongezwe kumphezulu wentambo, nto leyo ephucula uqweqwe lomphezulu wentambo. Uqweqwe oluthambileyo lunika intambo ukuqina kunye nemibala ehlala ixesha elide, ithintela ukurhawuzelelwa nokunyamalala. Zisetyenziswa kakhulu kwiitrawl zeplankton, zibonelela ngokushukuma okungashukumiyo kwaye zinomthamo ophantsi wokuthwala umthwalo kuneentambo zeKevlar. Iintambo zepolyethylene ezinamandla aphezulu, ezineemodulus eziphezulu zineempawu zomzimba ezintle kakhulu. Ngenxa yekristali yayo ephezulu kunye namaqela eekhemikhali angashukumiyo, iyamelana namanzi, umswakama, iikhemikhali kunye neekhemikhali. Ngenxa yoko iyamelana namanzi, umswakama, iikhemikhali kunye nemitha ye-ultraviolet, kwaye ngenxa yoko ayifuni kunyangwa ukuxhathisa kwe-UV. Ukuxhathisa ukubola, ukuxhathisa i-asidi kunye ne-alkali, ukuxhathisa okugqwesileyo kokurhawuzelelwa, kungekuphela nje imodulus ephezulu, kodwa ikwanobomi obuthambileyo, obude obuguquguqukayo, indawo yokunyibilika kwefiber yepolyethylene enamandla aphezulu phakathi kwe-144 ~ 152C, ukuvezwa kwexesha elifutshane kwindawo engqongileyo ye-110C akuyi kubangela ukuwohloka okukhulu kokusebenza.
