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 echanekileyo 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 nomgangatho ongaphezulu we-non-stick, 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 ephezulu yobushushu eguquguqukayo kwaye inamathele nakwi--70 ° C, ikhusela ukuqhekeka kwe-brittle kunye nokuvumela ukubambelela okuthembekileyo kwizicelo ze-cryogenic.

Iteyiphu ye-PTFE yobushushu obuphezulu inokuqhekeka okanye iqhekeke phantsi kokugoba ngokuphindaphindiweyo kunye neemeko zokuvula. Eli nqaku lichaza indlela yokuthintela oku ngokukhetha okufanelekileyo kwe-substrate (ifiber yeglasi eqinisiweyo), ubukhulu obufanelekileyo (0.18mm njengomgangatho), ukhetho lwe-adhesive ye-silicone, kunye neendlela ezichanekileyo zokufakela.

Ilaphu le-PTFE elinobushushu obuphezulu libonelela ngokuxhathisa okukhethekileyo kweekhemikhali, ukumelana neeasidi ezomeleleyo, iialkali, izinyibilikisi eziphilayo, kunye neegesi ezidliwayo. Eli nqaku lichaza izinto zalo ezixhathisayo, imida (isinyithi esinyibilikisiweyo se-alkali, i-agent eqinile ye-fluorinating), kunye nezinto eziphambili ezifana nobushushu, ugxininiso, kunye noxinzelelo lomatshini.

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.

Ukufakwa kwe-PTFE akuphelelanga kwilaphu le-fiberglass. Eli nqaku lizisa ii-substrates ezi-7 ezizezinye - i-aramid, i-carbon fiber, i-PBI, isinyithi esine-porous, i-graphite, i-asbestos (ikhutshwe ngaphandle), kunye ne-ceramic fillers - kunye neempawu zabo zenkqubo, izibonelelo, ukulinganiselwa, kunye nezicelo eziphambili.

Ilaphu eliphefumla kakhulu le-PTFE elinobushushu obuphezulu lidibanisa iipropati ezingezizo, ukuzinza kwe-thermal, kunye nokungena komoya. Eli nqaku liphonononga izicelo zalo eziphambili ekomisweni kwelaphu, ukusetyenzwa kokutya, ukwenziwa kwezinto ezihlanganisiweyo, izinto zombane, ukuhambisa umoya, ukukhuselwa kwendalo kunye nezinto zokwakha.

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, i-roller non-stick rollers, ukomiswa kwendawo), kunye nokulawulwa kwenkqubo esulungekileyo.
