Ukusuka kumqhaphu, i-hemp ukuya kwinayiloni, i-aramid, kunye ne-polymer, iintsinga zentambo ezahlukeneyo zimisela umahluko kukuqina kwentambo, ukomelela, ukuxhathisa umhlwa kunye nokumelana nokukhuhlana.Ukuze kuqinisekiswe ukuba intambo ingasetyenziswa ngokufanelekileyo ekuxhomeni, ekucimeni umlilo, ekunyukeni intaba, njl.njl., kufuneka ikhethwe ngokufanelekileyo ngokweempawu zayo kunye neemfuno zokhuseleko, ithobele imiqathango yokusetyenziswa, kwaye ilumkele ukusetyenziswa kwentambo ngokungafanelekanga.
· Imigca yokuxhoma
Imigca yokuxhomisa iyinxalenye ebalulekileyo yenkqubo yokuxhoma kwaye isetyenziselwa ukukhusela inqanawa ngokuchasene nefuthe lomoya, langoku kunye namandla olwandle kwiimeko eziqhelekileyo zokusingqongileyo ngelixa inqanawa ikwi-ankile.Ingozi yengozi ebangelwa kukuqhawuka kwentambo yokubophelela phantsi koxinzelelo xa ithelekiswa noko, ngoko ke iimfuno zokuqina, ukugoba ukumelana nokudinwa, ukuxhathisa umhlwa kunye nobude bentambo zingqongqo ngokugqithisileyo.
Iintambo ze-UHMWPE zezona zikhethwa kuqala kwiintambo zokubophelela.Ngaphantsi kwamandla afanayo, ubunzima buyi-1/7 yentambo yentsimbi yendabuko, kwaye inokudada emanzini.Iindidi ezahlukeneyo zokwakha kunye neentambo zeentambo ezingasetyenziselwa ukuphucula ukusebenza kwentambo kwisicelo esijoliswe kuyo.Kwizicelo ezisebenzayo, ukuphuka kwekhebula okubangelwa yimiba yendalo okanye ukusebenza okungafanelekanga komntu akunakungahoywa, okunokubangela ukulimala okukhulu komntu kunye nomonakalo wezixhobo.
Ukusetyenziswa okukhuselekileyo kweentambo zokuxhoma kufuneka kubandakanye kodwa kungaphelelanga kule miba ilandelayo: khetha iintambo ngokuhambelana noyilo lwamandla oqhawulo lwenqanawa, ukuze intambo nganye ibe kwindawo efanelekileyo yoxinzelelo;qaphela ukugcinwa kweentambo, khangela iimeko zeentambo rhoqo;lungisa ukuxhoma kwangexesha ngokwemozulu kunye neemeko zolwandle;ukuphuhlisa ulwazi ngokhuseleko lwabasebenzi.
·Intambo yomlilo
Intambo yokhuseleko lomlilo yenye yezinto eziphambili zezixhobo zokulwa nokuwa zokulwa nomlilo.Intambo yokulwa nomlilo yintambo ekhethekileyo yokukhusela, kwaye amandla, ubude kunye nokumelana nokushisa okuphezulu kwentambo zizinto ezibalulekileyo.
Imathiriyeli yentambo yokhuseleko lomlilo yintambo yentsimbi engundoqo engaphakathi, umaleko wefiber ophothiweyo wangaphandle.I-fiber ye-Aramid inokumelana nokushisa okuphezulu kwama-degrees angama-400, amandla aphezulu, ukuxhatshazwa kokugqoka, ukunyanzeliswa kwe-mildew, ukumelana ne-asidi kunye ne-alkali, kwaye yinto yokuqala yokukhetha iintambo zokukhusela umlilo.
Intambo yokuphuma emlilweni yintambo emileyo ene-ductility ephantsi kakhulu, ngoko ke inokusetyenziswa kuphela njenge-abseil.Zombini iziphetho zentambo yokhuseleko kufuneka zipheliswe ngokufanelekileyo kwaye nesakhiwo sentambo yelophu kufuneka sisetyenziswe.Kwaye ubophe umthungo we-50mm ngomtya wezinto ezifanayo, ubushushu butywinwe umthungo, kwaye ubophe umthungo ngerabha ehlanganiswe ngokuqinileyo okanye umkhono weplastiki.
·Intambo yokukhwela
Intambo yokunyuka intaba sesona sixhobo sibalulekileyo ekunyukeni intaba, kwaye iindlela ezahlukeneyo zokunyuka intaba ezinjengokunyuka, ukuhla nokukhusela ziyaphuhliswa ngeenxa zonke kuyo.Amandla empembelelo, ukudubeka kunye nenani lokuwa kwentambo yokunyuka zizinto ezintathu ezibalulekileyo zobugcisa beparamitha.
Iintambo zangoku zokukhwela zonke zisebenzisa iintambo zomnatha ezinomaleko womnatha ongaphandle ngaphandle kwemisonto emininzi ephothiweyo, kuneentambo eziqhelekileyo zenayiloni.Intambo yeentyatyambo yintambo yamandla, kwaye i-ductility ingaphantsi kwe-8%.Intambo yamandla kufuneka isetyenziselwe iiprojekthi ezinokuwa kwamandla, njengokunyuka amatye, ukunyuka intaba, kunye nokuhla.Intambo emhlophe yintambo emileyo ene-ductility engaphantsi kwe-1%, okanye ithathwa njenge-zero ductility kwimeko efanelekileyo.
Ayizizo zonke iintambo zokukhwela ezinokusetyenziswa zodwa.Iintambo eziphawulwe nge-UIAA① zinokusetyenziswa zodwa kwiindawo ezingekho mgangathweni kakhulu.Ubukhulu bentambo bumalunga ne-8mm kwaye ukomelela kweentambo eziphawulwe nge-UIAA akonelanga.Iintambo ezimbini kuphela ezinokusetyenziswa ngexesha elinye.
Intambo sesinye sezixhobo zokusebenza ezikhethekileyo.Abasebenzi kufuneka bakuqonde ukubaluleka kunye nemfuneko yokusebenzisa intambo ngokukhuselekileyo, balawule ngokungqongqo ikhonkco ngalinye lokusetyenziswa kweentambo, kwaye banciphise umngcipheko, ngokwenjenjalo bekhuthaza ukhuseleko nophuhliso oluzinzileyo loshishino.
