Ukuqonda i-PTFE i-Adhesive Tape kunye nokumelana nobushushu bayo
Ubume obusisiseko kunye neePropati
Iteyiphu encamathelayo ye-PTFE ine-polytetrafluoroethylene exhasayo kunye neentlobo ezahlukeneyo zokuncamathelisa ngaphambili. Izinzile kakhulu kumaqondo obushushu aphezulu kwaye ayisebenzi ngemichiza ngokulula. Umaleko we-polytetrafluoroethylene wenza umphezulu ungabambeleli kwaye ukwazi ukumelana namaqondo obushushu aphezulu kakhulu. Iglue ye-silicone, kwelinye icala, iqinisekisa ukuba iziqwenga ezimbini zihlala kunye nangona zifudumala.
Ngenxa yendlela iimolekyuli zayo ezakhiwe ngayo, i-PTFE izinzile kakhulu kumaqondo obushushu ukusuka -73 ° C ukuya +260 ° C eqhelekileyo. Ngenxa yobubanzi befestile esebenza kuyo, ezi teyiphu zinokusetyenziswa kwiindawo apho amaqondo obushushu aguquka ngokukhawuleza, apho achanabeka kumaqondo obushushu aphakamileyo ngalo lonke ixesha, nalapho ezinye izinto zinokuqhekeka okanye zithobeke.
Iimpawu zeNdawo eziPhambili kunye neeNkcazo
Iimpawu ezisebenzayo ze-PTFE iteyiphu encamathelayo idlulela ngaphaya kokumelana nobushushu. Ezi zixhobo zisebenza kakuhle ekuxhathiseni i-asidi, izinyibilikisi, kunye neoli, nto leyo ezenza zibe luncedo kwiindawo apho imichiza ilungiswa khona. Ukongeza, i-flame retardant kunye ne-abrasion-resistant-resistant iimpawu ziyenza ikhuseleke kwaye ihlale ixesha elide kwizicwangciso zemizi-mveliso.
Iiparamitha ezibalulekileyo ziquka ukungafani kobunzima be-0.08mm ukuya kwi-0.25mm, ngokusekelwe kwiimfuno zemveliso. Imixube yeglue isebenzisa iisistim ezisekelwe kwi-silicone ezikhethiweyo ngenxa yokuba zizinzile kumaqondo aphezulu kwaye azihambisani neekhemikhali. Imigangatho yomgangatho kunye nokhuseleko iqinisekiswa yimvume yamazwe ngamazwe efana ne-ISO 9001:2015, ukuthotyelwa kwe-FDA kwizicelo ezidibana ngqo nokutya, kunye nokuqatshelwa kwe-UL kwizicelo zombane.
Iimeko zokuSebenza eziQhelekileyo kunye nezicelo
Olunye usebenziso oluphambili lweteyiphu encamathelayo ye-PTFE esebenza kakuhle ngenene ikwiinkqubo zokutywinwa kobushushu. Iimpawu ezingabonakaliyo zigcina ukuhanjiswa kweqondo lokushisa ngokuzinzileyo ngelixa ugcina imveliso ekunamatheleni kwimivalo yokuvala. Ezi ntlobo ziyahambelana ne-FDA kwaye zigcina izixhobo zokulungiselela ukutya zicocekile ngelixa zikwaxhathisa ukosuleleka.
Ukukhutshwa komphezulu kwizitywini zobushushu, oomatshini beengxowa, kunye noomatshini bokuzalisa-ifomu, ezi teyiphu zisetyenziswa koomatshini bokupakisha. Ikhono lokuthintela imichiza liluncedo kwiiphakheji zamachiza kunye nezithambiso, apho uqinisekisa ukuba iimveliso ezingaphakathi ziyahambelana zisabaluleke kakhulu. Iiteyiphu ze-PTFE zisetyenziselwa ukuvelisa ukugquma izinto zokufudumeza, ukwenza imiphezulu yokukhulula ukubumba, kunye nesetingi zobushushu obuphezulu ukugcina umbane ungahambi.
Uhlalutyo lothelekiso: i-PTFE Adhesive Tape vs enye iTapes zobushushu obuphezulu
Ukunyamezela kweThermal kunye nokuFaniswa kokuSebenza
Xa ukhetha iiteyiphu ezikwaziyo ukumelana nobushushu, kubalulekile ukwazi ukuba i-PTFE isebenza njani ngokwahlukileyo kunezinye izinto ezifana ne-silicone, i-polyester, okanye i-Kapton. Xa evezwe kumaqondo obushushu aphezulu ngokuphindaphindiweyo, iteyiphu yokuncamathelisa ye-PTFE ihlala isenza ngcono kunezinye iinketho. Igcina amandla ayo okuncamathela kunye nokumila ngelixa ezinye izinto ziya kuthamba okanye ziqhekeke.
Iiteyiphu zeSilicone zibhetyebhetye kwaye zinokubunjwa ukuba zilingane, kodwa azinalo ukhuselo lwekhemikhali kunye neempawu ezingabambekiyo zezisombululo zePTFE. Ngelixa iiteyiphu zepolyester zilungile ekugcineni umbane ungekho, ziye ziyeke ukusebenza xa ubushushu bungaphezu kwe-150°C. Iiteyiphu zeKapton zilungile kusetyenziso lombane, kodwa azinazo iimpawu zokukhululwa ezifunekayo kwiinkqubo ezininzi zoshishino.
Iteyiphu encamathelayo ye-PTFE yahlukile kwezinye iinketho ngenxa yezi mpawu zilandelayo:
