Ịkwalite PTFE Adhesive Tape Power - Mkpuchi na Ngwọta Usoro kacha mma

Ijide ike - ikike nke teepu nrapado iji guzogide nrụgide siri ike ma nọrọ n'ọnọdụ n'okpuru ibu mgbe niile, karịsịa na okpomọkụ dị elu - bụ otu n'ime usoro arụmọrụ kachasị mkpa maka. PTFE teepu nrapado dị elu . Ike njide na-adịghị mma na-eduga na mwepu teepu, ihe nrapado, na mmetọ akụrụngwa.

Ụkpụrụ bụ isi maka imeziwanye ike njide bụ okpukpu abụọ: welie ike jikọtara ọnụ nke oyi akwa nrapado ma mee ka ike mgbochi ihu dị n'etiti nrapado na PTFE..

Aokai PTFE akwalitela ma mkpuchi na usoro ọgwụgwọ iji nweta arụmọrụ njide dị elu. Ntuziaka a na-ekpuchi usoro nhazi usoro n'ofe usoro nrụpụta isi abụọ a.

Nkwalite usoro mkpuchi mkpuchi - Iwulite ntọala ahụ

Usoro mkpuchi ahụ na-ekpebi kpọmkwem nhazi, nha nha nha, na ike njikọ na mkpụrụ - ntọala nke ike njide magburu onwe ya.

1. Mkpuchi mbụ - ihe ngwọta bụ isi maka nkwụsị adịghị mma nke PTFE

PTFE nwere ike dị ala nke ukwuu (18-20 dynes / cm), na-eme ka oyi akwa nrapado na-enwe ike ikpochapụ n'okpuru nrụgide oke okpomọkụ. A ghaghị imejuputa usoro mkpuchi primer tupu mkpuchi mkpuchi elu.

• Nhọrọ nke mbụ: A na-anabata ndị nnọchi anya njikọ Silane ma ọ bụ primers silicone pụrụ iche (ngwọta agwakọtara ya na resin tackifying na reactive silane). Maka mgbakwunye-ọgwụgwọ silicone PSA, vinyl ma ọ bụ epoxy na-arụ ọrụ silane na-arụ ọrụ na-ahọrọ.

• Isi ihe njikwa usoro:

  • Ihe nkiri primer dị obere: Jikwaa ọkpụrụkpụ ihe nkiri kpọrọ nkụ n'ime 0.5-2 μm - primer gabigara ókè na-etolite oke oke na-adịghị ike nke na-ebelata ike.

  • Zuru oke tupu ihicha: ihe mgbaze na-ekpochapụ nke ọma yana condensation/crosslink zuru oke tupu mkpuchi n'elu, na-egbochi mbugharị ihe mgbaze primer na nrapado elu.

  • Ngwọta dị n'ahịrị n'elu + mkpuchi primer: Na-eme ọgwụgwọ plasma ma ọ bụ corona n'ịntanetị na mkpụrụ PTFE ozugbo tupu ngwa primer iji zere attenuation nke ịgbalite elu.

2. Njikwa ziri ezi nke nrapado nha na ịdị n'otu

Ijide ike na-ebili n'ozuzu ya na ọkpụrụkpụ nrapado, ma oke mkpuchi nke ukwuu na-eme ka nrapado na-akpụ akpụ n'okpuru oke okpomọkụ ma na-ebelata ọrụ njide.

• Ọkpụrụkpụ nrapado akọrọ kacha mma: Silicone PSA na-enweta ike njide kacha mma na ọkpụrụkpụ akọrọ nke 30-60 μm.

• Ụzọ mkpuchi dị elu dị elu: Nabata mkpuchi rikoma, mkpuchi oghere oghere, ma ọ bụ mkpuchi micro gravure dị elu nke ọma iji mee ka ogologo ogologo na transverse ọkpụrụkpụ ndidi n'ime ± 2 μm . Ọkpụrụkpụ na-ezighi ezi na-ebute itinye uche na mgbakasị ahụ, na-eduga n'ọkpụkpụ na-amalite site na mpaghara kacha dị gịrịgịrị mgbe a na-ejide ule ike.

3. Nrapado mmiri mmiri pretreatment na nri usoro

• Vacuum defoaming: Degas nrapado mmiri mmiri n'okpuru agụụ mgbe agwakọta ma ọ bụ tupu mkpuchi iji zere ịgbasa voids n'oge ọgwụgwọ, nke na-eme dị ka mgbape isi mmalite n'okpuru mgbe niile ibu.

• Ngwakọta n'ahịrị na maturation: Maka nrapado silicone nwere akụkụ abụọ, wepụta igwekota static maka inye nri ozugbo ma jikwaa oge obibi mmiri mmiri iji hụ na mmeghachi omume mbido otu wee kpochapụ mpaghara na-adịghị ike na mpaghara.

• Ijikwa ịdị ọcha: Kwadebe isi mkpuchi ihe mkpuchi uzuzu yana yochaa mmiri nrapado site na katrij nzacha 5-10 μm iji gbochie adịghị ọcha nke na-ebute itinye uche.

Nkwalite usoro ọgwụgwọ - Mkpọchi na arụmọrụ

Ngwọta na-ekpebi njupụta crosslink ikpeazụ, ọkwa nrụgide dị n'ime, yana ọdịnaya obere molekul fọdụrụnụ - nke na-achịkwa ike njikọta ọnụ na nguzogide oke okpomọkụ.

1. kpo oku nzọụkwụ na ọgwụgwọ multi-mpaghara

Nghọta bụ isi: kpo oku nke nzọụkwụ na-eme ka e guzobe otu otu, netwọkụ nwere akụkụ atọ dị n'ime nrapado, na-ebuga arụmọrụ njide dị elu ma e jiri ya tụnyere ịsa achịcha dị elu nke otu ọkwa. Okpomọkụ na-ezughị ezu na-ebute nkwụsịtụ na-adịghị mma na oyi akwa na-ejikọta ọnụ; ekpo oke ọkụ nwere ike ịkpalite nrapado ịka nká ma ọ bụ oke nrụgide dị n'ime site na mbelata okpomọkụ na-adaghị adaba.

2. Ọgwụgwọ na-agwọta na maturation

• Ngwọta n'ahịrị n'ihu: Tọọ ngalaba oven gbatịrị agbatị tupu ikuku na-efegharị na okpomọkụ dịtụ ala karịa oke ikuku na-agafe agafe iji mee ka akụkọ ihe mere eme dị ogologo ma mezuo mmeghachi omume na-agafe agafe.

• Ngwọta maturation mpịakọta: Tinye teepu ọnya na-apụta n'ime oven nke na-ekpo ọkụ mgbe niile ( 40-60 Celsius maka awa 24-48 ) maka nchekwa dị iche iche. Usoro a:
