Ukuqonda iTape yeFilimu ye-PTFE kunye neempawu zayo ezincamathelayo
Ukuqulunqwa kwe-PTFE Film Tape
Iteyiphu yefilimu ye-PTFE iqulathe amacandelo amabini aphambili: umaleko wefilimu ye-PTFE kunye nenkxaso encamathelayo. Ifilimu ye-PTFE, ephuma kwi-polytetrafluoroethylene, inikezela ngezinto ezingenakunqanda, ezichasene neekhemikhali, kunye nokushisa okwenza le tape ibaluleke kakhulu. Le filimu ngokuqhelekileyo ibhityile kakhulu, ukusuka kwi-1 ukuya kwi-10 mils (0.001 ukuya kwi-0.010 intshi) ubukhulu, okuvumela ukuguquguquka kunye nokuhambelana kwiindawo ezahlukeneyo.
Umaleko wokuncamathelisa udla ngokwenziwa kwi-silicone okanye kwi-acrylic-based compounds, ekhethwe ngononophelo ukuncedisana neempawu zefilimu ye-PTFE. Ezi zincamathelisi zenziwe ngobunjineli ukuze zigcine amandla azo okudityaniswa kuluhlu olubanzi lobushushu kwaye zixhathise ukuthotywa kweekhemikhali, zizenze zilungele iimeko ezinomngeni apho iiteyiphu eziqhelekileyo zinokusilela.
Iindlela zokuncamathela kwi-PTFE Film Tape
I-adhesive kwi-tape yefilimu ye-PTFE isebenza ngokudibanisa komatshini kunye neekhemikhali. Xa isetyenziswe kumphezulu, i-adhesive-sensitive adhesive yenza uqhagamshelwano olusondeleyo, ivumela iamolekyu zayo ukuba zidibanise ne-substrate kwinqanaba le-microscopic. Olu nxibelelwano ludala ubudlelwane obuqinileyo obunokumelana noxinzelelo kunye neemeko zokusingqongileyo.
Ukuqulunqwa kwe-adhesive kubalulekile ekumiseleni iimpawu zayo zokusebenza. ekumgangatho ophezulu we-PTFE Iiteyiphu zokuncamathelisa ifilimu zisebenzisa izinto zokuncamathelisa eziphambili ezibonelela ngokugqwesileyo kwasekuqaleni, ukuncamathela kwexesha elide, kunye nokuchasana nezinto ezisingqongileyo ezifana nokuguquguquka kobushushu, ukufuma, kunye nokuvezwa kwe-UV. Ezi zakhiwo ziqinisekisa ukuba iteyiphu ihlala ikhuselekile kulo lonke ixesha lokuphila kwayo, nakwizicelo ezifunayo.
