Funsani

Gulu lazinthu

Q Kodi ndingayitanitsa makulidwe kapena utali wokhazikika?

A Inde. Timapereka makulidwe amtundu, makulidwe, ndi kutalika kwa roll kuti zigwirizane ndi dongosolo lanu. Lumikizanani ndi gulu lathu lazogulitsa ndi zomwe mukufuna komanso kuchuluka komwe mukufuna.
Q Ndisunge ndikugwira bwanji tepi?

Sungani pamalo ozizira, owuma kutali ndi kuwala kwa dzuwa ndi kutentha. Pewani kukhudzana ndi chinyezi kwanthawi yayitali. Sungani mpukutuwo muzopaka zake zoyambira pomwe sukugwiritsidwa ntchito.
Q Ndi nthawi yotani yotsogolera?

Sitima yapamadzi yokhazikika mkati mwa masiku 7 ogwira ntchito pambuyo potsimikizira kuyitanitsa; makonda angatenge nthawi yayitali. Tikutsimikizirani nthawi yotsogolera ndi inu pakuyitanitsa.
Q Kodi zomati

A Zomatira ndizochokera ku silicone, komabe, kasitomala amatha kusintha tepi yochokera ku acrylic, yomwe imapereka zomatira kwambiri.
Q Kodi pali kusiyana kotani pakati pa PTFE silikoni zomatira tepi ndi PTFE acrylic tepi?

A
Kutentha kachitidwe

● Zomatira za silika:

Kukhazikika kwapamwamba kwapamwamba kwambiri ndipo kumakhalabe kusinthasintha pa kutentha kochepa; oyenera kupalasa njinga matenthedwe ndi gaskets/zisindikizo.

● Zomatira za Acrylic:

Kuchita bwino kwa kutentha kwathunthu koma nthawi zambiri sikusinthika ngati silikoni; imatha kukhala yolimba kwambiri pakatentha kwambiri kapena kufewa pakatentha kwambiri.

Chemical kukana ndi chilengedwe

● Zomatira za silika:

Kukana kwabwino kwa chinyezi, kumizidwa m'madzi, kuwonekera kwa UV (pogwiritsa ntchito panja), ndi mankhwala ambiri; amasunga elasticity.

● Zomatira za Acrylic:

Kukaniza bwino kwamankhwala ndi UV m'malo ambiri koma osasinthika kwambiri kuposa silikoni; kukana kwanyengo kumadalira kapangidwe kake.

Kusinthasintha vs kukhazikika

● Zomatira za silicone pa PTFE:

Zosinthika kwambiri, zotha kutengera kusuntha, kugwedezeka, ndi kukulitsa kutentha popanda kutaya chisindikizo.

● Zomatira za Acrylic pa PTFE:

Nthawi zambiri kuuma; kugwira mwamphamvu koyamba koma kukhululuka pang'ono ndikuyenda; zabwino kwa zomangira olimba, mkulu-tack.

[PTFE Adhesive Tepi ] Kodi kutentha kwa kuwonongeka ndi theka la moyo wa mankhwala ophatikizira peroxide ziyenera kufananizidwa bwanji ndi zenera la machiritso a tepi ya Teflon?

Nkhaniyi ikufotokoza momwe angagwirizanitsire kutentha ndi theka la moyo wa peroxide crosslinking agents (BPO ndi DCP) ndi zenera la machiritso a tepi ya Teflon. Deta yapakati: BPO - 1-min theka la moyo pa ~ 131 ° C, 1-hr pa ~ 92 ° C, 10-hr pa ~ 72 ° C; DCP - 1-min pa ~ 171°C, 1-hr pa ~135°C, 10-hr pa ~115°C. Zolinga zofananira: zomatira zimafunikira 97-99% kuwoloka = 5-7 theka la miyoyo; kuchiritsa nthawi = 5-7 × theka la moyo pa kutentha kwa chandamale. Kubwerera kuwerengera kutentha kuchokera ku nthawi yopanga mzere wokhalamo kapena kuwerengera nthawi yochokera ku kutentha kovomerezeka.
[PTFE Adhesive Tepi ] Kodi pali kusiyana kotani pa zotsatira za kutentha kwa ma radiation ya infrared motsutsana ndi kutentha kwa mpweya wotentha pakufanana kwa mawonekedwe ophatikizika a zomatira za silicone?

Nkhaniyi ikufanizira kusiyana pakati pa kutentha kwa infrared radiation ndi kutentha kwa mpweya wotentha pamapangidwe ophatikizika ofanana a silicone zomatira wosanjikiza. Njira zosinthira kutentha: mpweya wotentha ndi convection-conduction, wodekha komanso wopita patsogolo, umapanga kutentha pang'ono; IR ndi mayamwidwe a radiation ndi mayamwidwe apamwamba kwambiri (ma micrometer mpaka mamilimita) kumapanga kutsetsereka kotsetsereka pamwamba kupita mkati. Zotsatira pakugawa kachulukidwe ka crosslink: mpweya wotentha umalola kuti magawo amkati ndi akunja alowemo kutentha kwanthawi yayitali nthawi imodzi, kutulutsa kachulukidwe kofanana ndi makulidwe; IR imayambitsa kusanjikiza pamwamba kuti kuchiritse khungu lowundana nthawi yomweyo lomwe limalepheretsa kutentha, zomwe zimapangitsa kuti kachulukidwe kakang'ono ka crosslink kuchepe kuchokera pamwamba mkati.
[PTFE Adhesive Tepi ] Ndi zotsatira zotani za kupsinjika kwa intaneti panthawi yopaka tepi ya Teflon yotentha kwambiri pa flatness ya gawo lapansi la PTFE ndi kufanana kwa zokutira zomatira?

Nkhaniyi ikuyang'ana zotsatira za kugwedezeka kwa intaneti panthawi ya Teflon yotentha kwambiri ya tepi pa PTFE gawo lapansi la flatness ndi zomatira zomatira zofanana. Zotsatira pa kutsika kwapansi kwa gawo lapansi: Kukakamira kopitilira malire zotanuka kumapangitsa kuti pulasitiki ikhale yotambasuka ndi makongono osasinthika (kutalikirana kwakutali, kupendekera kopingasa), kupanga kufooka, makwinya ndi mawonekedwe a wavy; PTFE imalowa pansi pa kukanidwa kosalekeza kumakhala 'kuzizira' pambuyo pozizira, kuchititsa kusamvana pamwamba; Kukangana kosiyana kosiyana kochokera ku kusafanana kwa ma roller kumapangitsa m'mbali zopindika, matuza apakati, komanso malekezero anthawi ndi nthawi.
[PTFE Adhesive Tepi ] Chitsanzo cha kusintha kwa mphamvu ya mgwirizano wa zomatira wosanjikiza Teflon mkulu-kutentha tepi pambuyo ukalamba kutentha.

Nkhaniyi ikufotokoza chitsanzo cha kusintha kwa mgwirizano mphamvu ya PTFE mkulu-kutentha tepi zomatira wosanjikiza pambuyo kukalamba kutentha. Chitsanzo cha magawo atatu: Pambuyo pochiritsa kukwera siteji (kutentha koyambirira kwa kutentha kwa 200-260 ° C, magulu otsalira otsalira akupitirizabe kuphatikizika, kugwirizana kumawonjezeka kwambiri); Gawo lokhazikika lokhazikika (njira zolumikizirana zimatsirizika, mgwirizano umakhalabe wokhazikika kwa nthawi yayitali); Kuwonongeka ndi kutsika siteji (nthawi yochulukirapo / kutentha kumayambitsa kuwonongeka kwakukulu kwa unyolo, mgwirizano umachepetsa, zomatira zimafewetsa ndikukhala zovuta). Zomwe zimayambitsa kulephera kwa mgwirizano (zotsalira zamkati zong'ambika) ndi kufinya (kuzizira kochokera m'mbali chifukwa cha kuchepa kwa modulus) zimawunikidwa.
[PTFE Adhesive Tepi ] Kodi kukana kukwawa komanso kukhazikika kwanthawi yayitali kwa tepi yotentha kwambiri ya Teflon kungasinthidwe bwanji?

Nkhaniyi ikupereka njira zowonjezerera kukana kukwawa komanso kukhazikika kwanthawi yayitali kwa tepi ya Teflon yotentha kwambiri. Njira zikuphatikizapo: Kukhathamiritsa kwa ma molekyulu a ma netiweki - high MQ silicone resin / chingamu chiŵerengero (1.2: 1–2: 1) imapanga madera okhwima olimba; kuphatikizidwa kwa magulu a phenyl (20-30 mol%) kumalepheretsa kuyenda kwa unyolo; crosslink molecular kulemera kulamulidwa pa 5,000-15,000 g / mol; Gradient modulus multilayer zomatira dongosolo - woyamba-anangula wosanjikiza (1-3μm) ndi silane lumikiza wothandizila, mkulu-modulus cohesive wosanjikiza (30-50μm) monga kukameta ubweya zosagwira mafupa, viscoelastic zinchito wosanjikiza (3-8μm) kwa pamwamba kunyowetsa; Nanofillers - silika woyaka (10-25 wt%) wokhala ndi kusinthika kwapamtunda kumapangitsa kulumikizana kosinthika.
