Maɓalli #1:Farashin PTFE
Budurwa PTFE (sunan ciniki polymer) yana da kyau azaman kayan hatimin ƙwallon ƙwallon don matsa lamba ƙasa da 5 ksi da yanayin zafi tsakanin -20 F da 400 F;duk da haka, yanayin zafinsa ya dogara da matsa lamba.Da yake magana game da matsa lamba, PTFE ba ya raguwa da kyau bayan an matsa shi.Lura cewa polymer ba ya aiki da kyau lokacin da ake fuskantar canjin yanayin zafi sama da 167 F. Ɗaya daga cikin mafi girman ƙarfinsa shine juriya na sinadarai, yana kusa da wanda ba a iya narkewa;wani ƙarfi ne musamman low gogayya.Hakanan yana da juriya da wuta.
Maɓalli #2:Gilashin Ƙarfafa PTFE
Ƙarfafa PTFE kamar yadda aka yi amfani da shi a cikin hatimi na ball bawul shine yawanci 15% fiber gilashin, ƙara yawan zafin jiki da ƙimar matsa lamba tare da budurwa PTFE.Kamar polymer da ba a ƙarfafa shi ba, gilashin ƙarfafa PTFE har yanzu yana da kyakkyawan juriya na sinadarai ban da caustics masu zafi da hydroflourics.Shi ma, yana da juriya da wuta kuma yana da ƙananan juzu'i, ko da yake ba ƙasa da ƙarancin budurwa PTFE ba.
Maɓalli #3:Bakin Karfe Karfafa PTFE
Akwai madadin nau'i na PTFE mai ƙarfafawa wanda wasu lokuta ana amfani dashi a cikin hatimin bawul ɗin ball: bakin karfe ƙarfafa PTFE.Wannan hadadden hatimin abu an yi shi da 50% polymer da 50% foda 316 bakin karfe.Matsakaicin zafinsa shine -20F zuwa 550F (dan kadan sama da budurwa PTFE) kuma yana da ƙarfin matsa lamba fiye da budurwa ko fiber gilashin da aka ƙarfafa PTFE.Shi ma, yana da juriya da wuta, duk da haka adadin gogayyarsa ya fi PTFE.
Maɓalli #4:KYAUTA
PEEK wani zaɓi ne lokacin da buƙatun ke ƙasa da kewayon zafin jiki na PTFE.PEEK yana aiki da kyau a cikin mahalli tare da yanayin zafi tsakanin -70F zuwa 600F, kuma ba shi da tasiri ta ci gaba da fallasa tururi da ruwan zafi.Ya fi polymer ƙarfi, amma kuma ya fi wuya.Babban koma bayansa, baya ga rigiditynsa, shine halin karyewar sa a yanayin zafi.
Maɓalli #5:UMHW Polyethylene
UHMW Polyethylene da alama ya zama zaɓi don ƙarin aikace-aikace na musamman, gami da waɗanda za a sami ƙarancin haske zuwa matsakaicin filaye.Matsayin matsinsa shine 1.5 ksi kuma kewayon zafinsa shine -70F zuwa 200F 1500 psi -57C zuwa 93C.UHMW Polyethylene shima yana da juriya mai kyau sosai.
Maɓalli #6:Polyether chlorinated
Ana amfani da polyether mai chlorinated a wasu lokuta azaman kayan hatimin ƙwallon ƙwallon ƙafa, yana aiki a yanayin zafi har zuwa 257 F. Yana aiki da kyau a gaban acid da kaushi idan ana iya jurewa tausasawa, kuma yana jure wa sinadarai sama da 300.Ba ya rarrafe, kuma baya son sha ruwa.
Seals yana Ci gaba da Haɓakawa:
Kayayyakin hatimi filin ci gaba ne mai ci gaba, amma waɗannan abubuwa shida da alama sune manyan masu fafutuka don zaɓin hatimin hatimin ƙwallon ƙwallon ƙwallon ƙafa.Babban halayen su suna kama da matsa lamba da aikin zafin jiki, ƙarancin juriya, juriya na sinadarai.
