Onke amatywina ngumguquli okhokelayo owaziwayo womgangatho ophezulu we-PTFE gaskets, izitywina, iiwasha kunye nezithinteli.
Onke amatywina anamava ekuboneleleni ngokuchaneka kweegaskets ze-PTFE, izitywini, iiwasher, kunye nezigqumatheli kuluhlu olubanzi lwamashishini kunye nokusetyenziswa.IPolytetrafluoroethylene (PTFE) luphawu lwentengiso lwaseDuPont lwepolymer.Yinto eyenziwe nge-fluoropolymer ye-tetrafluoroethylene equka ngokupheleleyo i-carbon kunye ne-fluorine.Ngokwemvelo i-hydrophobic (igxotha amanzi kunye namanzi aqulethe izinto) kwaye inomnye weyona coefficients ephantsi yokukhuhlana kuyo nayiphi na into eqinileyo.
I-PTFE ineempawu ezibalaseleyo zedielectric kwaye ibonelela ngokugqwesileyo kobushushu bobushushu obunoluhlu olusebenzayo lobushushu obuphakathi kwe -400°F ukuya kuma-500°F.I-PTFE yeyona plastiki imelana nekhemikhali eyaziwayo kwaye ayichatshazelwa lulwelo oluninzi oludlayo, umphunga, kunye neegesi.I-PTFE iqhele ukubonelelwa ngokobukhulu obusuka .002″ ukuya .250″ ubukhulu kwaye ihambelana neenkcukacha ze-FDA kunye ne-AMS, iyenza yamkeleke kuzo zombini iimveliso zonyango kunye nemveliso yokutya.
I-PTFE, ipholima engagcwaliswanga Iigaskets
Iigaskets zebakala le-PTFE zenziwa ukusuka kwi-100% imathiriyeli esulungekileyo esetyenziswa kwizicelo ezininzi jikelele.Ithambile kakhulu kwaye iyabumbeka kwaye ihlala isetyenziselwa imichiza ekwaziyo ukumelana neekhemikhali kunye neegaskets.Yenziwe ngokuthe ngqo kumvelisi we-resin kwaye ayizange iqhutywe ibe yimo.Inezona mpawu ziphezulu zokugquma umzimba kunye nombane kwaye iye yanda ukuxhathisa ukukhasa (uxinzelelo) phantsi komthwalo.Ibanga le-PTFE elinyulu linokubonwa ngombala walo omhlophe xa kuthelekiswa nebakala lomatshini le-PTFE.
PTFE, IgcwalisiweipholimaIigaskets
Iigaskets ezizaliswe yi-PTFE zenziwe kwi-PTFE edibanisa izongezo kunye nezihluzi ukuze kuphuculwe ukusebenza kwe-gasket.Oku kuphucula amandla e-gaskets okunxiba kunye nokwandisa indibaniselwano yayo ekhethekileyo yeekhemikhali, iipropathi zombane kunye nezombane.Ipolymer egcwalisiweyo lolona hlobo luxhaphakileyo lwe-PTFE gasket kusetyenziso lwemizi-mveliso njengoko lubonisa amandla omatshini aphuculweyo xa kuthelekiswa neNtombi ye-PTFE.Iglasi, i-carbon kunye ne-fiber particles zizizalisi eziqhelekileyo ezisetyenziselwa ukunyusa amandla omatshini we-gasket ngokuxhomekeke kwisicelo.
PTFE, YandisiweipholimaIigaskets
Impahla yegasket yePTFE eyandisiweyo iveliswa ngokwandisa iVirgin PTFE kusetyenziswa inkqubo eyenza i-microstructure efanayo kunye nefibrillated enamandla alinganayo kuwo onke amacala.Oku kuthetha ukuba i-polymer eyandisiweyo ayinabo ubuthathaka bolwakhiwo okanye "iinkozo".Kuba akukho zongezo zifunwayo, i-polymer eyandisiweyo ikwanazo ukumelana neekhemikhali ezikhethekileyo zepolymer enyulu.I-PTFE eyandisiweyo ithambile kakhulu kwaye ibhetyebhetye ngakumbi kuneegaskets eziqhelekileyo ze-PTFE kwaye ngaloo ndlela ihambelana ngokulula nemigangatho erhabaxa nerhabaxa.Izinto eziphathekayo zilula ukucinezela kwaye zinciphisa ukuhamba kunye nokuhamba okubandayo.
