Iikhemikhali ezibalulekileyo ze-PTFE, ubushushu, ukufuma, kunye nokuchasana kombane kuyenza ibe yimathiriyeli efanelekileyo nanini na xa iimveliso, izixhobo, kunye namalungu kufuneka aqine kwaye athembeke nakwezona zicelo zinzima.Ngaphezulu koku, i-PTFE ucingo olugqunyiweyo luzidla ngokuhlala ubushushu obuphantsi kunye nokumelana nomlilo okwenza kube lukhetho olulungileyo kuluhlu olukhula rhoqo lweemveliso, amacandelo, kunye nezicelo.
Iintambo zePVC zenziwa ngexabiso eliphantsi kakhulu ngenxa yokuba akufuneki ukuba zihlangane neqondo lobushushu eliphezulu ezenziwa ziintambo zePTFE.I-PVC imele iPolyvinyl Chloride eyikhompawundi eyenzelwe ukuba isetyenziswe kwizinto zombane kunye nezinye izinto zangaphakathi.
Iintambo ze-elektroniki ze-PVC zidibana ne-105 ° C yeqondo lokushisa kwi-300 okanye i-600 volts.Zenziwa ngemisonto yobhedu ebhetyebhetye kunye nokugqunyelelwa kwePVC kwiikhondaktha zangaphakathi.Ngamanye amaxesha beza nesikhuselo se-aluminiyam jikelele kunye nentambo yocingo lobhedu.
Ngoku usazi ulwakhiwo lwentambo yePVC mhlawumbi uya kuqonda ukuba kutheni intambo ye-PTFE ibiza kakhulu.Ikhompawundi ye-PTFE isetyenziselwa ukwenza i-200°C imathiriyeli yobushushu ukugquma abaqhubi bobhedu.Ubunjineli obubandakanyekayo ekudaleni ikhebula le-200 ° C libandakanyeka kakhulu kunenkqubo yokudala ikhebula le-105 ° C.
Iikondaktara zangaphakathi zeentambo ze-PTFE nazo zine-PTFE yokugquma ebizwa ngokuba yi-Type E okanye i-M16878/4 ekwadibana nobushushu obuphezulu be-200 ° C.Zenziwa ngemisonto yobhedu enesilivere, nto leyo ethetha ukuba iindleko zobhedu kunye nesilivere ephezulu kufuneka zibandakanywe kumaxabiso kwiintambo ze-PTFE.
Isizathu sokugqibela samaxabiso aphezulu kwiintambo ze-PTFE yinto yokuba inyikima eJapan ichaphazele umenzi wonke we-PTFE ikhompawundi ebithumela ikhompawundi kubavelisi becingo be-PTFE.Oko kwadala ukunqongophala okukhulu kweengcingo ze-PTFE kwimarike eye yanyusa amaxabiso ngokunjalo.
Andifuni ukuthi intambo yePVC kulula ukuyenza, kodwa xa uyithelekisa nentambo ye-PTFE ibonakala ngathi yihambo epakini.Zombini iintambo zinemvume ye-UL kunye ne-CSA kunye nokuthotyelwa kwe-RoHS, kodwa iintambo ze-PTFE zinokusetyenziswa ngaphandle, kumaqondo obushushu aphezulu kwaye zixhathisa amanzi, iigesi, i-oyile, izinyibilikisi nokunye okuninzi.
