Yintoni umbhobho weTeflon (PTFE)?

1. Kutheni ibizwa ngokuba ngumbhobho weTeflon (PTFE)? Umbhobho weTeflon uthiywa njani?

Umbhobho weTeflon, owaziwa ngokuba ngumbhobho we-PTFE, owaziwa njenge "king of plastics", yipolymer ephezulu yemolekyuli eyenziwe nge-tetrafluoroethylene njenge-monomer. I-waxy emhlophe, i-translucent, ubushushu obugqwesileyo kunye nokumelana nokubanda, ingasetyenziswa ixesha elide kwi-180 ~ 260ºC. Esi sixhobo asiqulathanga naziphi na i-pigments okanye izongezo, ayinyangeki nge-asidi, i-alkali-resistant kunye nezinyibilikisi ezahlukeneyo ze-organic, kwaye phantse azinyibiliki kuzo zonke izinyibilikisi. Kwangaxeshanye, i-PTFE ineempawu zokunganyangeki kobushushu obuphezulu kunye ne-coefficient ephantsi kakhulu yokukhuhlana, ngoko ingasetyenziselwa ukuthambisa, iyenze ibe ngumbhobho wokugquma ofanelekileyo wokucoca ngokulula umaleko wangaphakathi wemibhobho yamanzi.

2.Iintlobo zemibhobho yeTeflon

①. I-Teflon smooth bore tube yenziwe nge-100% ye-PTFE resin kwaye ayiqulathanga naziphi na ii-pigments okanye izongezo. Ilungele ukusetyenziswa kwi-aerospace kunye nobuchwepheshe bezothutho, i-electronics, amacandelo kunye ne-insulators, ukuveliswa kweekhemikhali kunye namayeza, ukulungiswa kokutya, isayensi yendalo, isampuli yomoya, izixhobo zokuhambisa ulwelo kunye neenkqubo zokunyanga amanzi. Yonke imibhobho ifumaneka kwi-anti-static (ibhokisi) okanye iinguqulelo ezinemibala.

②. I-Teflon corrugated pipe yenziwe nge-100% ye-PTFE resin engaphathwanga kwaye ayiqulathanga naziphi na ii-pigments okanye izongezo. Inokuguquguquka okugqwesileyo kunye nokumelana ne-torsional, ukubonelela ngokusebenza okugqwesileyo kwizicelo ezifuna i-radii ye-bend engqongqo, amandla amakhulu okuphatha uxinzelelo okanye ukuxhathisa ukutyumza. Imivumbo iyafumaneka ngamadangatye, iiflange, iikhafu okanye indibaniselwano yezisombululo zemibhobho ephuculweyo ezininzi. Yonke imibhobho ifumaneka kwiinguqulelo ze-anti-static (carbon).

③. Iimpawu zeqondo lokushisa kunye nokumelana nokubola kweetyhubhu zeTeflon ze-capillary zisetyenziswe ngokubanzi kumashishini angaguqukiyo, afana neshishini lemichiza, i-pickling, i-electroplating, iyeza, i-anodizing kunye namanye amashishini. Iityhubhu zeCapillary ikakhulu zinokumelana nokugqwesa okugqwesileyo, ukuxhathisa okulungileyo kokunyuka, ukumelana nokuguga okugqwesileyo, ukusebenza kakuhle kokuhambisa ubushushu, ukuxhathisa okuncinci, ubungakanani obuncinci, ubunzima bokukhanya kunye nesakhiwo esibambeneyo.
