I-PTFE i-fiberglass tape idinga iziqinisekiso ezintathu eziphambili zokhuseleko: i-UL (ukhuseleko lombane kunye nomlilo), i-FDA (ukuthotyelwa koqhagamshelwano lokutya), kunye ne-ISO 9001: 2015 (ulawulo lomgangatho). Iiteyiphu eziqinisekisiweyo zibonelela ngokusebenza okufanayo, ubomi benkonzo obude, kunye nexabiso eliphantsi lilonke lobunini nangona ixabiso eliphezulu ngaphambili. Soloko uqinisekisa iziqinisekiso ngqo namaqumrhu akhuphayo.

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 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.

Kwiiteyiphu ze-PTFE zobushushu obuphezulu phantsi kokucwiliswa kwexesha elide, i-PTFE substrate ihlala inert yekhemikhali, kodwa i-adhesive layer iyindawo ebuthathaka. Amanzi buthathaka abicah PSA; Amanzi anetyuwa anyusa isantya umhlwa. Kwiikhemikhali ezinobundlobongela, i-fluorosilicone okanye i-perfluoropolyether adhesives - okanye iteyiphu ye-PTFE engena-adhesive-iyadingeka. I-peel ilahleko yamandla ukuya kwi-40% emva kweeyure ezingama-48 emanzini.

Iteyiphu yobushushu obuphezulu be-PTFE esetyenziswa kwizicelo zoqhagamshelwano lokutya kufuneka ihlale ngaphakathi kwemida yobushushu echaziweyo: ≤260°C ukuze isetyenziswe ngokuqhubekayo, ≤300°C kwiincopho ezimfutshane (imizuzu), kwaye ingaze ibe ngaphezu kwe-327°C (ukubola). I-FDA kunye ne-EU imigaqo ayicacisi umda wexesha jikelele - ubude boqhagamshelwano obukhuselekileyo buxhomekeke kwiqondo lokushisa kwaye kufuneka luqinisekiswe ngovavanyo lokufuduka olufanisa iimeko zangempela.

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.

Ukukhethwa kwephepha lokukhululwa okanye i-substrate yefilimu kunye ne-arhente yokukhulula ichaphazela ngokuthe ngqo ukuzinza kokugcinwa kunye nokusebenza kwe-peeling ye-PTFE ye-tape ephezulu yokushisa. Eli nqaku lithelekisa i-PET kunye ne-kraft substrates yephepha kunye ne-silicone vs.

Iiteyiphu ze-PTFE zobushushu obuphezulu zisetyenziselwa ukugquma kombane, kodwa iimeko ezikwi-frequency ephezulu kunye ne-high-voltage zibeka imingcipheko eyodwa: ukuqhawuka kombane, ukukhutshwa ngokuyinxenye, ukuguga kwe-thermal, ilahleko ye-high-frequency signal, kunye novakalelo lokusingqongileyo. Eli nqaku lichaza ingozi nganye kunye nendlela yokuphepha.
