Iteyiphu yobushushu obuphezulu be-PTFE isetyenziswa kuwo wonke amanqanaba amathathu osetyenziso lwezonyango: ukhuseleko lwesixhobo sokuvala inzala (iitreyi ze-autoclave, ukupakishwa kwetywina lokushisa), unyango lomphezulu wesixhobo (i-low-friction coating, ukugqunywa kombane), kunye nezixhobo ezifakelwayo (i-vascular grafts, sutures). I-Biocompatibility iqinisekiswa nge-ISO 10993, kwaye i-FDA 21 CFR 177.1550 iseka ukhuseleko lwezinto ezisisiseko.

Iteyiphu yobushushu obuphezulu be-PTFE inokuxhathisa kakubi kwimitha ye-ionizing. Kwi-1 kGy nje ekutyhilekeni kwe-gamma, amandla e-tensile ehla ukuya kuthi ga kwi- ~25% yoqobo. Ifanelekile kuphela kwiindawo eziphantsi kwedosi (ukutya / inzalo yonyango <10 kGy). Kwishishini lenyukliya okanye iziphekepheke, sebenzisa i-polyimide okanye i-PEEK endaweni yoko.

Iteyiphu ye-PTFE yobushushu obuphezulu ifuna ukugcinwa okufanelekileyo ukugcina ukunamathela kwayo, ukuguquguquka, kunye nokukhulula ukusebenza. Iimfuno eziphambili zibandakanya ukulawulwa kweqondo lokushisa (10-30 ° C), umswakama ongaphantsi kwe-60%, ukuphepha ukukhanya, ukuhlukaniswa kweekhemikhali, ukubekwa ngokuthe nkqo, kunye nomoya. Landela ulawulo lwe-inventri ye-FIFO kwaye uhlole rhoqo.

Eli nqaku lichaza indlela yokuthintela ungcoliseko kunye nomonakalo wokusebenza kwicala elingabambeleliyo le-PTFE iteyiphu yobushushu obuphezulu ngexesha lenkqubo yokwambathisa. Izicwangciso eziphambili zibandakanya ukulawulwa komthombo (unyango oluchanekileyo lomhlaba), ukuhlukaniswa ngokomzimba (iifilimu ezikhuselayo yobushushu obuphezulu be-PTFE isetyenziswa kuwo wonke amanqanaba amathathu osetyenziso lwezonyango: ukhuseleko lwesixhobo sokuvala inzala (iitreyi ze-autoclave, ukupakishwa kwetywina lokushisa), unyango lomphezulu wesixhobo (i-low-friction coating, ukugqunywa kombane), kunye nezixhobo ezifakelwayo (i-vascular grafts, sutures). I-Biocompatibility iqinisekiswa nge-ISO 10993, kwaye i-FDA 21 CFR 177.1550 iseka ukhuseleko lwezinto ezisisiseko.

Njengomvelisi wokuqala we-PTFE iiteyiphu zobushushu obuphezulu, i-Jiangsu Aokai New Materials apha ichaza iimpembelelo zeendlela zokupholisa kunye namazinga okupholisa ekusebenzeni kwe-PTFE ephilisiwe iteyiphu zobushushu obuphezulu.I. Undoqo weempawu ze-PTFE Crystallization kunye noLawulo lweRayithi lokuPholisaI-PTFE su

I-Jiangsu Aokai New Materials, umenzi womthombo oqeqeshiweyo we-PTFE iteyiphu yobushushu obuphezulu, wabelana ngolwazi lobuchwephesha kuwe.PTFE (Teflon) iteyiphu yobushushu obuphezulu ingasetyenziswa ngokuqhubekayo kuluhlu lobushushu lwe -196℃ ukuya kwi-260℃. Kwizicelo ezininzi, umda wokumelana nobushushu
