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 nemithetho ye-EU ayicacisi umda wexesha jikelele - ubude boqhagamshelwano obukhuselekileyo buxhomekeke kubushushu kwaye kufuneka buqinisekiswe 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.

Ukukhetha iteyiphu efanelekileyo ye-PTFE yobushushu obuphezulu kwibhedi eshushu yomshicileli we-3D ifuna ukugxila kwizalathisi ezine eziphambili: ukumelana nobushushu (ukuya kuthi ga kwi-260 ° C +), i-fiberglass-reinforced substrate (0.18mm efanelekileyo), i-adhesive backing ye-silicone kunye nomphezulu ongeyena intonga, kunye nobubanzi obufanelekileyo / ukunyamezela. Esi sikhokelo sikunceda ukuba uphephe ukulwa, intsalela, kunye nokusilela koshicilelo.

Ubushushu beglasi yokutshintsha (Tg) ye-silicone yokuncamathelisa i-adhesive yoxinzelelo ijikeleze -120 ° C - isezantsi kakhulu kune-adhesives ye-acrylic. Le Tg ye-ultra-low igcina i-PTFE i-tape yobushushu obuphezulu eguquguqukayo kwaye inamathele nakwi-70 ° C, ikhusela ukuqhekeka kwe-brittle kunye nokwenza ukuba ukunamathela okuthembekileyo kwizicelo ze-cryogenic.

Iteyiphu ye-PTFE yobushushu obuphezulu inokuqhekeka okanye iqhekeke phantsi kokugoba ngokuphindaphindiweyo kunye neemeko zokuvula. Eli nqaku lichaza indlela yokuthintela oku ngokukhethwa kwe-substrate efanelekileyo (i-glass fiber reinforced), ubukhulu obufanelekileyo (0.18mm njengesiqhelo), ukhetho lwe-adhesive ye-silicone, kunye neendlela ezichanekileyo zokufakela.

Ukukhethwa kwephepha lokukhulula okanye i-substrate yefilimu kunye ne-arhente yokukhulula ichaphazela ngokuthe ngqo ukugcinwa kozinzo kunye nokusebenza kwe-peeling ye-PTFE ye-tape ephezulu yokushisa. Eli nqaku lithelekisa i-PET kunye ne-kraft paper substrates kunye ne-silicone vs.

Iiteyiphu ze-PTFE zobushushu obuphezulu zisetyenziselwa ukugquma kombane, kodwa iimeko ezikwi-frequency ephezulu kunye ne-high-voltage zenza 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.

Eli nqaku lichaza indlela yokuthintela ungcoliseko kunye nomonakalo wokusebenza kwicala elingabambeleliyo le-PTFE itheyiphu yobushushu obuphezulu ngexesha lenkqubo yokwambathisa. Izicwangciso eziphambili zibandakanya ukulawulwa komthombo (unyango oluchanekileyo lomhlaba), ukuhlukaniswa ngokomzimba (iifilimu ezikhuselayo, i-roller non-stick rollers, ukomiswa kwendawo), kunye nolawulo lwenkqubo esulungekileyo.

Zeziphi iziQinisekiso emandizijonge kwiTeyiphu yoKutya kwiBanga le-PTFE?Ezona zifundo zibalulekileyo emazijongwe kwiteyiphu encamathelayo ye-PTFE ekwibakala lokutya ukuze isetyenziswe kurhwebo kukuthotyelwa kwe-FDA, isiqinisekiso se-NSF, kunye ne-ISO 9001:2015 imigangatho yolawulo lomgangatho. Ezi zatifikethi ziqinisekisa ukuba i-polytetrafluoro

Uninzi lwabaphathi beentengo bafuna eyona ntsebenzo ilungileyo xa bejonga kukhetho lokuncamathelisa kwimizi-mveliso. Kufuneka bawazi umahluko phakathi kwe-PTFE fiberglass tape kunye ne-silicone tape. Umaleko we-Polytetrafluoroethylene unika i-PTFE i-fiberglass tape iipropathi zayo ezinkulu ezingabambekiyo ngelixa uthunga i-fiberglass giv
