Imoto enemeko ekhoyo yokusetyenziswa kwezinto ezilukiweyo (2) : I-airbag ye-airbag iyinxalenye ebalulekileyo yenkqubo yokhuseleko lwesithuthi, amashishini emveliso yasekhaya ye-airbag wire ikakhulu ne-Zhejiang Hailide New Material Co., Ltd., i-jiangsu hengli chemical fiber Co., Ltd., China leliphi iqela Co., Ltd kunye ne-invista ifayibha ekhethekileyo (i-Shanghai) Co., Ltd., njl. Phakathi kwabo, iZhejiang Hailide ngumenzi oyintloko we-polyester airbag yarn, enesabelo semarike yehlabathi engaphezulu 60%. I-Invista ngumvelisi omkhulu wocingo lwe-nayiloni ye-airbag. Abavelisi bangaphandle be-airbag filament ikakhulukazi babandakanya iToray Corporation yaseJapan, i-PHP FIBERS yaseJamani, njl.n i-airbag, ishishini le-airbag laseTshayina liya kuba nophuhliso olungcono.

Ukukhetha i-airbag fiber

Ukusukela ekuvelweni kwe-airbag, uninzi lwesabelo semarike yocingo lwe-airbag yamandla aphezulu enayiloni engama-66 yocingo oluntsonkothileyo. I-Polyamide ineempawu zemodyuli yokuqala ephantsi, ubude obufanelekileyo ngexesha lekhefu, ukuqina okulungileyo, ukuxhathisa ukunxiba kunye ne-enthalpy ephezulu, ukufunxa kakuhle kwamandla kunye nokuchasana kwempembelelo, ukumelana nobushushu obugqwesileyo, ukusebenza kakuhle kokusonga. Inayiloni engu-46 kunye nenayiloni yesi-6 nayo ingasetyenziselwa ukwenza amalaphu e-airbag. I-Akzo Nobel iphuhlise i-nayiloni engama-46 engafakwanga intambo yeengxowa zomoya ezinendawo yokunyibilika eyi-285 ° C, eneempawu ezifanayo nenayiloni engu-66 kodwa ixabisa ngaphezulu. Indawo yokunyibilika kunye ne-enthalpy ye-nylon 6 i-filament iphantsi kune-NYLON 66, kodwa ingenziwa ibe yi-airbag engcono emva konyango olukhethekileyo. Ilaphu le-airbag lenziwe nge-Saty Gard inayiloni eyi-6 ye-filament eveliswe yi-Allied Signal ibonise ukuxhathisa okungcono kokukrazula, ukugotywa kunye nokugcinwa kwamandla kune-airbag yelaphu eyenziwe nge-nylon 66, kwaye yenza kakuhle kwiimvavanyo zempembelelo, ukuguga kunye nokutshisa.

Ukwengeza, i-polyester filament isenokusetyenziswa njengezinto ezingasetyenziswanga kwiingxowa zomoya. I-polyester ineenzuzo zexabiso eliphantsi, akukho mpembelelo icacileyo yokutshintsha kokufuma, ukomelela okuphezulu, ukuxhathisa okulungileyo kweekhemikhali, ukugcinwa kwemilo elungileyo kunye nokuphinda kusetyenziswe lula. Ixabiso lemveliso yelaphu lengxowa yomoya lingancitshiswa malunga nama-40% endaweni yenayiloni. Ukumelana nobushushu obuphezulu kunye nokumelana nempembelelo yelaphu le-polyester ayilunganga njengelaphu le-nylon, kodwa ngophuhliso lwetekhnoloji yokuguqulwa kwefiber kunye ne-air bag yokugqiba iteknoloji, iipropati zayo zisenendawo enkulu yokuphucula. IFIBERS ye-PHP yaseJamani iphuhlise i-polyester eyongeziweyo ehlengahlengisiweyo ukuvelisa amalaphu e-airbag aneempawu ezithelekiseka ne-polyamide 66 kunye nokuphucula ukumelana nobushushu. I-Hoechst, inkampani yaseJamani, iphuhlise ukuqina okuphezulu kwe-polyester filament, kunye nelaphu le-airbag eyenziwe ngayo libonise ukusebenza kakuhle kukulinganisa okusingqongileyo kunye novavanyo lwengozi yemoto. Ngenxa yokufumana ukufuma okuphantsi, i-polyester ayilulanga ukuba iphinde ibuyele kumsonto phambi kokuba i-calender ifakwe emva kokufunxwa kokufuma, kwaye inokugcina umoya ophantsi wokungena ngaphakathi kubomi benkonzo yengxowa yomoya. Ke ngoko, i-polyester iye yaba lugxininiso lokwandisa ingqalelo yabaphuhlisi, kwaye ubungakanani belaphu le-airbag elukwe ngesilika yepolyester liya likhula kancinci kancinci. Okwangoku, i-polyester isetyenziswa malunga neepesenti ezingama-30 zeengxowa zomoya.

Ukukhetha ilaphu le-airbag

Amalaphu agqunyiweyo aneengenelo ze-thermal conductivity ephezulu, ulawulo oluchanekileyo lokungena komoya, ukusika ngokulula kunye nokuthunga, kunye nemiphetho engaqhawukiyo, kodwa ayisonge ngokulula kwaye ithobeke ngokukhawuleza ekuhambeni kwexesha, ngaloo ndlela inokukhokelela ekungaphumelelini okuyingozi. Ukongezelela, isikhwama somoya sohlobo lokuthunga sineemfuno eziphezulu kwintambo yokuthunga kunye nenkqubo yokuthunga. Ke ngoko, ilaphu le-airbag elilula, elithambileyo, elincinci, elinobuhlobo ngakumbi kokusingqongileyo kwaye linokuphinda lisetyenziswe, lingagqunywanga, elenziwe ngokupheleleyo libe lisikhokelo sophuhliso lobuchwepheshe. Amalaphu angagqunywanga kufuneka axinene kakhulu kwaye abe nomgangatho ophezulu kakhulu, kodwa asafuna ukunyanzeliswa komoya, okunzima ukuwenza, kodwa kuqikelelwa kwaye kuzinzile. Ii-airbags ezingafakwanga zikhupha umoya ngokuyintloko ngeepores zelaphu, ezinokubekwa kuxinzelelo oluphantsi kwaye zikhulule umoya kwiqondo lobushushu elisezantsi, ngaloo ndlela kuncitshiswe ukubakho kokutshiswa kobuso nentamo okanye ukwenzakala xa i-airbag isetyenziswa. Okwangoku, ii-airbags ezingafakwanga zisetyenziswa kakhulu kwimarike, kwaye iimoto ezininzi zangaphandle ezikumgangatho ophezulu zisebenzisa ii-airbags ezenziwe ngokupheleleyo.

Amandla aphezulu kunye nokunyanzeliswa okuphantsi kwesikhwama somoya sisitshixo sokuhlangabezana neemfuno zokusetyenziswa. Ngoko ke, kwinkqubo yokwaluka, umbutho uthungelwe ngokusondeleyo kunye nesakhiwo esilukiweyo esicacileyo, ubude be-weave plain ubude be-float, isakhiwo esizinzileyo, ukugqithiswa komoya omncinci, ukomelela kwelaphu nako kuphezulu. Kwilaphu le-airbag elineemfuno eziphezulu zokusebenza ezibanzi, ifayibha ehlanganisiweyo, ifayibha eneprofayili, okanye ukusetyenziswa kwezixhobo ezininzi eziluhlaza ukuxuba okanye indlela ye-interweave yokuluka, ukuze kuphuculwe ukusongwa, ukuguquguquka, kunye nokuncamathela kunye nokwaleka, njl. Ii-nonwovens nazo ziyaqala ukusetyenziswa kwii-airbags. Ukongeza ekuphuculeni ukusebenza kwezinto kunye nokunciphisa iindleko, isikhokelo sophando esiphambili selaphu le-airbag likwabandakanya ukuphuculwa kobukrelekrele kunye nokhuseleko. Ngokubhekiselele kukhuseleko, i-azide ye-sodium isetyenziswa ngokubanzi kwimveliso ye-automobile airbag generator, enetyhefu kakhulu. Emva kokusebenza, i-sodium eqinile iya kuveliswa. Ukuba i-sodium eqinile idibene namanzi, iya kutshisa ngokuthe ngqo, ibangele umonakalo wesibini. Ke ngoko, njengenye yezalathiso zophuhliso lwexesha elizayo, i-airbag yemoto iya kuthatha indawo i-azide ye-sodium kunye nezinye iigesi, ezinjengomxube we-hydrogen kunye nomoya okanye umxube we-helium.
