PTFE Yakawedzerwa Pepa / Tepi

Zvikamu zveZvigadzirwa

tsananguro

Pepa rePTFE rakawedzerwa rakagadzirwa kubva ku100% Virgin PTFE. Maitiro aya ekugadzira akakosha anoita kuti simba rekudhonza rive rakaenzana kumativi ese. Zvakare, chinhu ichi chiri nyore kudzvanya uye chinoderedza kuyerera kwemvura inoyerera uye inotonhora. Gasket rePTFE rakawedzerwa igasket rinogara richishandiswa rinogona kutsiva mamwe marudzi ese ePTFE gasket. Zvinhu izvi zvinoenderana nemitemo yeFDA yekubatana kwechikafu.

Chivharo chePTFE Joint Sealant chakawedzerwa chinogonawo kuwanikwa kuMicflon.

Zvinhu zvirimo

Expanded Polytetrafluoroethylene (ePTFE) inomiririra kufambira mberi kukuru mu tekinoroji yekuvhara, yakabva ku100% virgin PTFE. Kusiyana nePTFE yakajairwa, ePTFE inoitwa nenzira yakasarudzika yekuwedzera. Izvi zvinogadzira chimiro chakasiyana che microporous fibrous, zvichichinja zvakanyanya hunhu hwayo hwemuviri. Mugumisiro mukuru weiyi nzira yekugadzira ndeyekugadzirwa kwesimba rekudhonza rakaenzana munzira dzese dziri mbiri uye dzakachinjika. Simba iri remativi akawanda rakakosha nekuti rinoramba katsika kePTFE yakajairwa yekukanganisa kuenzana pasi pekumanikidzwa.

Zvakanakira

Chimwe chezvakanakira zvikuru zve ePTFE sheet material ndiko kudzvanywa kwayo kwakanyanya kana tichienzanisa ne PTFE yakasimba. Kupfava uku kunoita kuti ikwanise kuenderana zvakanaka nenzvimbo dzisina kurongeka, dzakakwenywa, kana dzakakuvara, zvichiita kuti ive nechisimbiso chakasimba uye chakavimbika kunyangwe paine mabhaudhi mashoma. Hunhu uhwu hunoderedza mukana wekubuda kwemvura kunowanzo sangana nezvinhu zvisingaenderane zvakanyanya panzvimbo dzisina kukwana. Uyezve, chimiro che ePTFE chinoderedza zvakanyanya matambudziko ekukwira (deformation pasi pemutoro unoenderera mberi) uye kuyerera kwechando (extrusion yezvinhu pasi pekumanikidzwa pakupisa kwekunze), izvo zvinogara zvichigumira paPTFE yakajairika. Kugadzikana uku kwakanyanya kunovimbisa kusimba uye kugara kwenguva refu kwechisimbiso kwenguva yakareba uye mamiriro akasiyana ekushanda.

Kushanda kwayo kwakasiyana-siyana kunoita kuti ePTFE sheeting ive mhinduro yepasi rose mumhuri yePTFE, inokwanisa kutsiva magasket ePTFE akachekwa, akazadzwa, kana akaputirwa muzvishandiso zvakawanda. Kusashanda kwayo kwemakemikari kwakakosha, kwakagara nhaka kubva kuPTFE isina makemikari, zvinoreva kuti inodzivirira kurwiswa nemakemikari ese pamhando dzakasiyana dzekupisa, zvichiita kuti ive yakakodzera munzvimbo dzine hukasha. Pamusoro pezvo, kutevedzera kwemidziyo iyi mitemo yeFDA (yakadai se21 CFR 177.1550) kunosimbisa kukodzera kwayo kushandiswa kwakaoma kunosanganisira kusangana zvakananga nechikafu, zvinwiwa, uye mishonga.

Kuwedzera pafomu repepa, Expanded PTFE Joint Sealant, inowanzo pihwa setepi inochinjika kana tambo ine glue backing, inopa mabhenefiti akafanana asi muchimiro chegasket. Iyi sealant tepi yakakodzera kuvhara maflange makuru, akaomarara, kana asiri emhando yepamusoro apo kucheka gasket yepepa kusingashande kana kutambisa. Inoenderana zviri nyore nemaumbirwo akaomarara uye inopa chisimbiso chakavimbika chine simba rakafanana rekudzivirira makemikari, kushivirira tembiricha, uye hunhu hwakaderera hwe creep semapepa e ePTFE, zvichiita kuti ese ari maviri ave mhinduro dzekuchengetedza dzinoshanda zvakanyanya dzemashandisirwo emaindasitiri anoda mari.
