Ngophuhliso lwe-5G, isomisi seenwele singene kwisizukulwana esilandelayo, kwaye imfuno yokomisa iinwele iyanda.I-Fiberglass eyomeleziweyo inayiloni (PA) ngokuzolileyo iye yaba yinto eyinkwenkwezi kwi-casings dryer casings kunye nemathiriyeli yokutyikitya kwisizukulwana esilandelayo sezomisi zeenwele eziphezulu.
I-Fiberglass eyomeleziweyo ye-PA66 idla ngokusetyenziswa kwimibhobho yezomisi zeenwele ezikumgangatho ophezulu, ezinokonyusa amandla kunye nokwandisa amandla obushushu.Nangona kunjalo, njengoko iimfuno zokusebenza kwesomisi seenwele ziba phezulu nangaphezulu, i-ABS, eyayiyeyona nto iphambili yeqokobhe, yatshintshwa ngokuthe ngcembe yi-fiberglass eqiniswe ngePA66.
Okwangoku, izinto eziphambili ezichaphazela ukulungiswa kwe-high-performance fiberglass eyomeleziweyo ye-PA66 i-composites ibandakanya ubude be-PA fiberglass imicu enqunqiweyo, unyango olungaphezulu lwe-fiberglass eqoshiwe imicu ye-PA kunye nobude bayo bokugcinwa kwi-matrix.
Emva koko makhe sijonge izinto zemveliso yeglasi yefiber eqiniswe ngePA66~
ubude bePA fiberglass zinqunqwe imisonto
Xa i-fiber yeglasi iqiniswa, ubude bee-PA ezinqunqiweyo zemisonto enye yezinto eziphambili ezimisela i-fiber-reinforced composites.Kwi-fiberglass emfutshane eqhelekileyo eyomeleziweyo ye-thermoplastics, ubude befayibha bukuphela (0.2 ~ 0.6) mm, ngoko xa izinto zonakaliswe ngamandla, amandla ayo angenamsebenzi ngenxa yobude obufutshane befayibha, kunye nenjongo yokusebenzisa i-fiberglass eyomeleziweyo yenayiloni (PA). ) isebenzisa ubulukhuni obuphezulu kunye namandla aphezulu efayibha ukuphucula iimpawu zomatshini zenayiloni, ngoko ubude befayibha budlala indima ebalulekileyo kwiipropati zomatshini wemveliso.Xa kuthelekiswa nendlela eyomeleziweyo yegilasi emfutshane, imodulus, amandla, ukuxhathisa, ukungakhathali, ukumelana nefuthe, ukumelana nobushushu kunye nokumelana nokunxitywa kwenayiloni ende yeglasi eyomeleziweyo, iphuculwe, yandisa ukusetyenziswa kwayo ezimotweni, kwizixhobo zombane, koomatshini kunye nomkhosi. .
Unyango lomphezulu wefiberglass zinqunqwe imisonto for PA
Amandla okudibanisa phakathi kwe-fiberglass kunye ne-matrix yenye into ebalulekileyo echaphazela iipropati ze-mechanical of composite.Iipolima ezomeleziweyo zeFiberglass zinokusebenza kakuhle kuphela ukuba zenza ibhondi yobuso obusebenzayo.Kwifiber yeglasi eyomelezwe kwiresin ye-thermosetting okanye i-polar thermoplastic resin composite materials, umphezulu wefiberglass unokunyangwa nge-agent edibanisayo ukwenza iqhina lekhemikhali phakathi kweresin kunye nomphezulu we-fiberglass, ukuze ufumane i-interfacial bonding esebenzayo.
Ugcino Ubude beI-FiberglasskwiNylon Matrix
Abantu benze uphando oluninzi malunga nokuxutywa kwe-fiberglass eyomeleziweyo yeresin ye-thermoplastic kunye nenkqubo yokubumba imveliso.Kufunyaniswa ukuba ubude bemisonto ye-fiberglass enqunqiweyo kwimveliso ihlala incinci ukuya ngaphantsi kwe-1mm, encitshiswe kakhulu xa kuthelekiswa nobude bokuqala befiber.Emva koko, isenzeko sokuqhekeka kwefayibha ngexesha lokusetyenzwa kwafundwa, kwaye kwafunyaniswa ukuba iimeko zokusetyenzwa kunye nezinye izinto ezahlukeneyo zinempembelelo ekuqhekekeni kwefayibha.
isixhobo factor
Kwi-design ye-screw kunye ne-nozzle, kuyimfuneko ukuphepha ukuxinwa kakhulu kunye nokutshintsha ngokukhawuleza kwisakhiwo.Ukuba ijelo lokuhamba lincinci kakhulu, liya kuchaphazela ukuhamba kwamahhala kwefiber yeglasi, okuya kubangela umphumo wokucheba kwaye kubangele ukuphuka;ukuba kukho utshintsho ngokukhawuleza kwisakhiwo, kulula kakhulu ukuvelisa Uxinzelelo olongezelelweyo loxinzelelo lutshabalalisai-fiberglass.
Inkqubo factor
1. Ubushushu bomphanda
Uluhlu lweqondo lokushisa elisetyenziswe xa kusetyenzwa iipelisi eziqinisiweyo kufuneka zibe ngaphezu kwe-280 ° C. Oku kungenxa yokuba, xa iqondo lokushisa liphezulu, i-viscosity ye-melt iya kuncitshiswa kakhulu, ukwenzela ukuba i-shear force esebenza kwifiber iyancipha kakhulu.Kwaye ukophuka kwe-fiberglass kwenzeka ikakhulu kwicandelo lokunyibilika kwe-extruder.ngenxa yokuba i-fiber yeglasi yongezwa kwipolymer enyibilikisiweyo, inyibilika ixutywe kunye nefiber yeglasi ukugubungela i-fiber yeglasi, edlala indima yokuthambisa kunye nokukhusela.Oku kunciphisa ukophuka kwefiber ngokugqithisileyo kunye nokunxitywa kwezikrufu kunye nemigqomo, kwaye kuququzelele ukusasazwa kunye nokuhanjiswa kweefiber zeglasi ekunyibilikeni.
2. Ubushushu bomngundo
Indlela yokungaphumeleli kwe-fiberglass kwi-mold ubukhulu becala kukuba iqondo lokushisa lokubumba liphantsi kakhulu kunelo lokunyibilika.Emva kokuba i-melt igeleza kwi-cavity, i-frozen layer yenziwe eludongeni lwangaphakathi ngokukhawuleza, kwaye ngokupholisa okuqhubekayo kwe-melted, i-frozen layer iqulunqwa.Ubukhulu beglasi ye-fiberglass buyaqhubeka bukhula, ukuze umaleko ophakathi oqukuqelayo ube mncinci kwaye ube mncinci, kwaye inxalenye yefiber yeglasi ekunyibilikeni ibambelela kumaleko angumkhenkce kwaye esinye isiphelo sisahamba kunye nenyibilika, ngaloo ndlela senza udidi olukhulu. ukucheba amandla kwifiberglass ekhokelela ekwaphukeni.Ubunzima bomgangatho oqingqiweyo okanye ubungakanani bomgca ohamba ngokukhululekileyo buya kuchaphazela ngokuthe ngqo ukuhamba kwe-melt kunye nobukhulu be-shear force, leyo ichaphazela iqondo lomonakalo kwi-fiberglass.Ubunzima bomaleko onomkhenkce kuqala buyanda kwaye buyancipha kunye nomgama ukusuka kwisango.Kuphela embindini, ubukhulu bomaleko obukhenkcezisiweyo buyanda ngokuhamba kwexesha.Ngoko ekupheleni kwecavity, ubude befiber buya kubuyela kwinqanaba elide.
3. Impembelelo yesantya sokujija ivuliwei-fiberglassubude
Ukonyuka kwesantya se-screw kuya kukhokelela ngokuthe ngqo ekwandeni koxinzelelo lwe-shear olusebenza kwi-fiberglass.Kwelinye icala, ukonyuka kwesantya se-screw kunokukhawulezisa inkqubo yeplastiki yepolymer, ukunciphisa i-viscosity enyibilikayo, kunye nokunciphisa uxinzelelo olusebenza kwifiber.Oku kungenxa yokuba isikrufu samawele sibonelela ngamandla amaninzi afunekayo ekunyibilikeni.Ke ngoko, impembelelo yesantya se-screw kubude befiber inemiba emibini echaseneyo.
4. Isikhundla kunye nendlela yokongeza i-fiber yeglasi
Xa i-polymer inyibilika kwaye ikhutshiwe, yongezwa ngokubanzi kwizibuko lokuqala lokutyisa emva kokuxuba ngokulinganayo.Nangona kunjalo, kwinkqubo yokunyibilika kwe-fiberglass ye-nayiloni eqinisiweyo (PA), i-polymer kufuneka yongezwe kwi-port yokuqala yokutya, kwaye iya kunyibilika kwaye yenziwe ngeplastiki.Emva koko, iintambo ze-fiberglass ezinqunqiweyo ze-PA zongezwa kwi-port yokutya esezantsi, oko kukuthi, ukondla okulandelayo kwamkelwe.Oku kungenxa yokuba ukuba zombini i-fiberglass kunye ne-polymer eqinileyo yongezwa ukusuka kwizibuko lokuqala lokutyisa, i-fiberglass iya kwaphuka ngokugqithisileyo ngexesha lenkqubo yokuhambisa eqinileyo, kunye nomphezulu ongaphakathi we-screw kunye nomatshini uya kuqhagamshelana ngokuthe ngqo kunye ne-fibegrlass, ebangela ukuba i-fiberglass ibe mbi kakhulu. ukuguga okunzulu kunye nokukrazula kwesixhobo.
