ʻO ke kaula hoʻopaʻa kaʻa (Puka, puka makani, kukui uila)
Kaʻa hoʻopaʻa paʻa
ʻO ka ʻāpana sealing automotive kekahi o nā ʻāpana koʻikoʻi, hoʻohana nui ʻia i ka puka, ka puka makani, ke kino o ke kaʻa, ka lani, ka pahu mīkini a me ka pahu mālama (ʻeke) etc. kaiapuni i loko o ke kaʻa, e pāʻani i ka mea noho kaʻa, nā lako uila a me nā mea hana ancillary o ka pale nui. Me ka hoʻomohala ʻana o ka ʻoihana kaʻa, ʻo ke koʻikoʻi o ka nani, ka mālama ʻana i ke kaiapuni a me ka hana ʻoluʻolu o ka sealing strip e lilo i mea kaulana. ʻO ka SEALING SYSTEM (automo-bile SEALING SYSTEM) i hoʻokomo ʻia ma nā ʻāpana like ʻole o ke kaʻa ua noiʻi kūikawā ʻia a hoʻomohala ʻia i loko o ka ʻoihana kaʻa o nā ʻāina ʻē, a ʻo kona koʻikoʻi ke huki nei i ka manaʻo nui. 1. E like me ka inoa o nā ʻāpana hoʻopaʻa ʻana (mau ʻāpana), ʻo ka hoʻokaʻawale ʻana: engine HOOD seal, a hiki ke māhele ʻia i mua, ʻaoʻao a me hope; PILI PUKA; Nā pale WINDOW no ka Windows ea mua a ma hope; SIDE window seal (SIDE Window seal); Sila SUNROOF; Sila Puka Mua; Hoʻopaʻa paʻa ʻana o ka puka alakaʻi puka (GLASSRUN CHANNEL); ʻO loko a me waho (waiwai)(WAISTLINE); SEAL PALAPALA; ʻAi-noise sealing strip; E like me ka anti-dust. 2. E like me nā hiʻohiʻona SEALING, hiki ke hoʻokaʻawale ʻia i ka sila WEATHERSTRIP a me ka sila nui. Ma waena o lākou, ua hoʻolako ʻia ke kāʻei hoʻopaʻa ʻana i ka wā me ka hollow sponge bubble tube, ʻoi aku ka maikaʻi o ka mālama ʻana i ka mahana a me ka haʻahaʻa. ʻO nā loina hoʻopaʻa wā maʻamau i hoʻohana ʻia, ʻo ia ke kaula hoʻopaʻa pani puka, ke kaula hoʻopaʻa pahu, ka uhi uhi pahu mīkini, a pēlā aku. i ka hoʻohui ʻia ʻana o ka hoʻohuihui ʻana o nā mea lāʻau lapaʻau, hiki ke hoʻokaʻawale ʻia i ke kaula hoʻopaʻa paʻa maʻemaʻe - i haku ʻia i hoʻokahi pahu; ʻElua kaula hoʻopaʻa hoʻopaʻa hoʻohuihui -- i haku ʻia me ke kolu paʻa a me ke kolu ʻōhuʻa, pinepine i loko o ke kāpili paʻa ma ke ala o ke koʻi i loaʻa nā mea iwi iwi; Sila hoʻohuihui ʻekolu - ʻelua ʻano o ka sealant (he ʻulaʻula kekahi o ia) a me ka sealant sponge, maʻamau i loaʻa kahi iwi metala a me nā fiber i hoʻoikaika ʻia i loko o ka sealant. ʻEhā hui hoʻopaʻa paʻa paʻa - Shanghai Shenya Sealing parts Co., Ltd. i alakaʻi i ka hoʻomohala ʻana a me ka hana ʻana o ka hui hoʻopaʻa hoʻopaʻa ʻia i haku ʻia me 4 mau ʻano o nā mea lāʻau lapaʻau, ma ka ʻili (bubble tube) a uhi ʻia me kahi ʻāpana lahilahi o mea hoʻopili pale pale, i mea e hoʻomaikaʻi hou ai i ke ola lawelawe o nā sila. 4. E like me ke ʻano o ka hoʻokaʻawale ʻana i nā mea, hiki ke hoʻokaʻawale ʻia i ke kaula sealing; Paʻa paʻa paʻa; Hoʻopaʻa sila hoʻoheheʻe wela wela. 5. Hoʻokaʻawale ʻia e like me ka mokuʻāina lapaʻau ili, hiki ke hoʻokaʻawale ʻia kekahi ʻili hoʻopaʻa sila ma hope o ka hoʻomaʻamaʻa hou ʻana, hiki ke hoʻokaʻawale ʻia i loko o ke kaula hoʻopaʻa ʻana; Ili uhi uhi sila kaula; Aia nā ʻāpana sila lole. 6. ʻO ka hoʻokaʻawale ʻana i ka hana kūikawā, ʻo kekahi mea hoʻopaʻa sila he hana naʻauao uila, e like me ka anti-clamping sealing strip.

Hoʻohui ʻia ka Ethylene propylene diene diene (EPDM) e ka polymerization o ka ethylene a me propylene monomers me kahi liʻiliʻi o ka diolefin non-conjugated. Hōʻike ʻia ke ʻano o ka polymer e nā paʻa pālua unsaturated i ke kaulahao nui a me nā paʻa pālua unsaturated i ke kaulahao lālā. No laila, loaʻa iā ia ke kūpaʻa maikaʻi o ka wā, ke kū ʻana o ka wela, ka pale ʻana o ka ozone, ka uv resistance linear a me ka hana hoʻoponopono maikaʻi a me ka haʻahaʻa haʻahaʻa haʻahaʻa deformation mau loa, no laila ʻo ia ka mea i makemake ʻia no ka hana ʻana i nā ʻāpana sealing. I kēia manawa, ke hoʻohana nei ka hapa nui o nā mea hoʻopaʻa paʻa automotive i ka EPDM ma ke ʻano kumu kumu. Wahi a nā ʻāpana like ʻole a me nā hana o nā ʻāpana sealing, i ka hoʻohana pono ʻana, ka vulcanization, ka pale, ka hoʻoikaika ʻana, nā lako ʻōnaehana hana a me nā mea i hāʻawi ʻia (e like me ka colorant, foaming agent) i hoʻohui ʻia i nā mea EPDM e hana i kahi paʻa paʻa (me ka ʻeleʻele adhesive. a me ke kala kala) a me ka sponge adhesive. ʻO ka mea hoʻopaʻa kaʻa kaʻa ka mea nui o ka elasticity maikaʻi a me ke kū'ē ʻana i ka deformation compression, ka pale ʻana i ka wā kahiko, ka ozone, ka hana kemika, kahi ākea ākea o ke ana wela (-40 ℃ ~ + 120 ℃) EPDM rubber foam a me ka composite paʻa, i loaʻa kahi mea metala kūikawā. a me ke alelo buckle, lōʻihi, maʻalahi e hoʻouka. Ua hoʻohālikelike ʻia me nā mea hana kaʻa nui.
