Awọn tubes Teflon jẹ awọn tubes fluoroplastic ti a ṣe lati awọn ohun elo polytetrafluoroethylene nipasẹ didapọ, ṣiṣe ọmọ inu oyun, titẹ tutu, sintering ati itutu agbaiye.
Awọn tubes Teflon ni awọn ohun-ini to dara julọ:
①Isọdipúpọ edekoyede kekere;
② Ipata ipata: acid to lagbara ati resistance alkali, ati pe gbogbo awọn kemikali ko ni fesi (ni iwọn otutu giga ati fluorine ati iṣesi irin alkali), le koju “Aqua regia” ipata;
③Mimọ ara ẹni: polytetrafluoroethylene jẹ gidigidi lati faramọ;
④ Ko ṣe flammable;
⑤ Giga otutu resistance: PTFE teflon ohun elo otutu le de ọdọ -70 ° C ~ 260 ° C;
⑥ High Resistance: Teflon tube pẹlu giga resistance, iṣẹ idabobo ti o dara julọ;
⑦ Anti-aging: Teflon Tube iṣẹ ti ogbologbo ti ogbologbo jẹ dara julọ, igbesi aye iṣẹ pipẹ.
Ti ogbo ti okun PTFE ko le ṣe akiyesi, iṣẹ ti awọn ọja yoo dinku lẹhin ti ogbologbo, nitorina, iṣelọpọ ti pẹ, a ni lati ṣe awọn ọna ti o pọju lati dena.
Awọn alemora teepu ti Teflon tube awọn ọja ti wa ni vulcanized pẹlu efin curing eto. Agbara ooru ti vulcanizate rẹ le ni ilọsiwaju nipasẹ idinku tabi yago fun lilo imi-ọjọ imi-ọjọ, eyiti o le dinku tabi imukuro sisopọ agbelebu polysulfide ati ni akọkọ ṣe agbejade imi-ọjọ kan tabi isopo-agbelebu disulfide.
Lilo peroxide jẹ pataki lati ṣaṣeyọri resistance ooru to dara, bi imularada pẹlu peroxide ṣe agbejade awọn ọna agbelebu erogba-erogba ti o jẹ iwọn otutu diẹ sii. Ifarabalẹ pataki yẹ ki o san si awọn afikun miiran nigba lilo peroxide. Fun apẹẹrẹ, yiyan awọn antioxidants nilo lati ni okun sii, bi ọpọlọpọ ninu wọn ṣe dabaru pẹlu peroxide, vulcanization.
Ni afikun, nigba lilo peroxide, dinku iye awọn ohun elo acid lati ṣe idiwọ awọn cations peroxide lati jijẹ, ti o yorisi vulcanization kekere ti okun titẹ-giga (ni irisi lile kekere, modulus kekere ati ṣeto funmorawon giga). Ṣafikun awọn agbo ogun ipilẹ, gẹgẹbi zinc oxide tabi oxide magnẹsia, nibiti o ti ṣee ṣe, le nigbagbogbo mu imudara ọna ṣiṣe ti peroxide pọ si. Tun ni ipa epo paraffin dara julọ, fẹ lati yago fun lilo epo hydrocarbon aromatic ati epo.
