isishwankathelo
I-PTFE (i-polytetrafluoroethylene)-i-tube ene-lined iba yinto engundoqo ye-vascular interventional catheters ngenxa ye-lubricity yayo egqwesileyo, udonga oluncinci, ukuguquguquka okunamandla kunye namandla aphezulu. Maitong Intelligent Manufacturing™Ine-coating ye-dip ephezulu, i-extrusion yamahhala kunye neenkqubo ze-mandrel extrusion, ngaloo ndlela ityhala ukusebenza kweetyhubhu ezifakwe kwi-PTFE ukuya kwiindawo eziphakamileyo kunye nokubonelela ngamathuba angenamkhawulo woyilo kunye nokusetyenziswa kwee-catheters zokungenelela. Ndiyabulela kwinkqubo yokulawula umgangatho engqongqo, iMaitong Intelligent Manufacturing™Ukuzinza kwemveliso kuye kwaqatshelwa ngamxhelo mnye ngabathengi.
umbhalo
Xa kuthelekiswa ne-vascular interventional catheters kwixesha elidlulileyo, uyilo lweemveliso ze-catheter zanamhlanje ziye zanda kakhulu, ezibandakanya amacandelo achanekileyo afana neetyhubhu ze-lining, i-adhesive layers, i-braided layers, kunye nezixhobo zangaphandle. Ukwenza ubungqingqwa bodonga lwecatheter lube mncinci kwaye ubukhulu bangaphakathi bube bukhulu yinjongo yokuba abavelisi becatheter abangenelelayo baqhubeke nokulandela. I-PTFE (i-polytetrafluoroethylene) ityhubhu edibeneyo, ene-lubricity egqwesileyo, udonga oluncinci, ukuguquguquka okunamandla kunye namandla aphezulu, isetyenziswa ngokubanzi kwi-microcatheters, i-catheters ephakathi, i-catheters yokufunxa, i-catheters yesikhokelo, i-catheters yokuxhasa, njl. izingxobo zokukhusela.
Nangona kunjalo, ukufezekisa ukulingana phakathi kobukhulu, ukuguquguquka kunye namandla e-PTFE (i-polytetrafluoroethylene) imibhobho edibeneyo ngumngeni obalulekileyo ekuphuhliseni imveliso kunye nenkqubo yokucubungula, kubandakanywa ukubunjwa kwesakhiwo esiyinkimbinkimbi, ukuqhutyelwa kwezinto, ulawulo lwenkqubo yamanyathelo amaninzi, i-extrusion Kukho ubunzima obuninzi obunjalo. njengolawulo oluchanekileyo lwenkqubo kunye nokukhethwa kweendlela zokubumba.
Ngokuqhubeka ngokutsha kwetekhnoloji kunye nokuphuculwa kwenkqubo, i-Maitong Intelligent Manufacturing™ izibophelele ekuphuhliseni uthotho lweetyhubhu ezinomgangatho ophezulu wokusebenza we-PTFE ukuhlangabezana nemfuno ekhulayo yeecatheter ezisebenza kakhulu kushishino lwezonyango.
Dip coating (ukwenziwa kwefilimu) inkqubo:
Ukusasazwa okugxininiswe kwe-PTFE kuqatywe ngokulinganayo kwingcingo engundoqo yesinyithi kwaye i-sintered kwaye yaqina ukwenza i-uniform yokwaleka, kwaye ucingo olungundoqo lwesinyithi lususwa ngokuthe ngcembe ukuze lufumane umbhobho we-PTFE ngokuguquguquka okugqwesileyo.
Inkqubo ye-extrusion yasimahla:
Emva kokuxuba i-PTFE powder kunye nezinyibilikisi zezinto eziphilayo kunye ne-lubricants ukwenza i-preform, yenziwe kwimilo yetyhubhu ngoncedo lwe-extruder kunye ne-sintered ukwenza udonga lwetyhubhu lube luncinci kwaye lufane, kwaye isakhiwo sengqolowa siphuculwe, ngaloo ndlela sinikeza ityhubhu ephezulu. amandla axial kunye nokuqina.
Inkqubo Extrusion nge mandrel:
Ukudibanisa iinzuzo zefilimu ephosiweyo, i-mandrel isetyenziselwa ukuncedisa ukubunjwa kwe-extrusion ukuqinisekisa ukufana kunye nokuguquguquka kodonga lombhobho we-lining ngelixa iphucula kakhulu amandla ayo. Ukongeza, le nkqubo iphelisa imfuneko yokufaka i-mandrel kwakhona, igcina iimpawu zokubambelela kwindawo yombhobho, ilungele ukuqhubeka nokuphononongwa kwe-braiding, kwaye iphucula kakhulu ukusebenza kakuhle kwemveliso.
Ukusebenza kwemveliso phantsi kweenkqubo ezahlukeneyo:
Uvavanyo lwedatha lubonisa ukuba i-Maitong Intelligent Manufacturing™ iqhubele phambili ukusebenza kweepayipi ezifakwe kwi-PTFE ukuya kwiindawo eziphakamileyo, kwaye ukusebenza kwemveliso kuye kwafikelela okanye kudlule kwinqanaba eliqhelekileyo kwimarike.
Ubukhulu bodonga oluncinci kakhulu kunye nokufana
I-thinnest wall thickness of PTFE-lined tubes eveliswa yinkqubo ye-extrusion yamahhala ingafikelela kwi-intshi ye-0.00075 (malunga ne-19 microns), ephucula ukuguquguquka kunye nokucaca ngelixa ukunciphisa i-catheter ububanzi kunye nokunciphisa umonakalo wezicubu.
Amandla aphezulu okuqina
I-Maitong Intelligent Manufacturing™'s PTFE-imibhobho enemigca igcina igudileyo, ilungile, iindonga ezibhityileyo ngelixa inamandla aphezulu, ngaloo ndlela iphucula ukuqina.
Ulawulo oluchanekileyo lokunyamezela
Ukusebenzisa i-mandrel (i-silver-plated copper wire) iteknoloji ye-extrusion, i-diameter engqongqo yangaphakathi kunye nolawulo lokunyamezela kodonga lufezekisiwe, ukubonelela ngenkxaso ethembekileyo yee-catheters zokungenelela.
Ulawulo lomgangatho
I-Maitong Intelligent Manufacturing™ iye yakha i-workshop ecocekileyo yeKlasi ye-10,000 ngokungqongqo ngokuhambelana nenkqubo ye-ISO13485 ukusuka ekutyeni ukuya ekupakisheni, yonke into igqitywe kwi-workshop ecocekileyo yeKlasi ye-10,000 ukuqinisekisa ukuba iimveliso zihlangabezana neemfuno zebhayoloji zezixhobo zonyango. Kwangaxeshanye, ixhotyiswe ngezixhobo zokuvelisa eziphambili, izixhobo zokulinganisa ezichanekileyo, kunye neendlela ezingqongqo zokuhlola kunye nokuvavanya ukuqinisekisa ukuba umgangatho wemveliso uyahlangabezana neemfuno zezixhobo zonyango.
