Ua lilo nā ʻāpana hoʻopaʻa PVC i mea punahele i ka puka kila plastik a me nā paʻi hoʻopaʻa puka makani no ka mea ʻaʻole lākou e haki a maʻalahi ke wili. Akā ʻo 2-3 mau makahiki wale nō, ua ʻike ʻia ka pilikia. ʻO ka hoʻokaʻawale ʻana o nā plasticizers PVC, kahi pilikia paʻakikī o ka ʻoihana honua, ua ʻike maopopo ʻia i nā kaula sealing PVC.
Ma muli o ka hoʻokaʻawale ʻana o ka plasticizer, hoʻohaumia ʻia ka ʻaoʻao e ka ʻōpala, ua pōkole ka lōʻihi, ua pōkole ka ʻāpana haʻihaʻi, a nui nā pilikia o ka hoʻopaʻa ʻana. Eia nō naʻe, ua hoʻohana ʻia ka hoʻohana ʻana i nā plasticizer defect a me PVC recycled, ka mea i hoʻonui i nā pilikia o ka ʻoihana holoʻokoʻa. Ke hoʻomaka nei ka hopena o ka PVC sealing strip.
EPDM EPDM sealing strips I ka ho'omaka 'ana o ka makahiki 2000, ua ho'opuka ka 'āina i ke kauoha kīvila e kapu i ka ho'ohana 'ana i ka polyvinyl chloride PVC sealing strips, a paipai i ka ho'ohana 'ana i EPDM EPDM sealing strips a me MVQ silicone rubber sealing strips. EPDM sealing strip, kahi kiʻekiʻe kiʻekiʻe sealing strip i hoʻohana ʻia i nā kaʻa a me nā kaʻaahi, ua ʻae ʻia e ka ʻoihana kūkulu.
ʻO kaʻoiaʻiʻo, ua hoʻohana nuiʻia i kaʻoihana puka a me ka puka makani ma hope o 2002. I kēlā manawa, ua komo mālie nā puka a me nā puka makani i ke au o nā alahaka haʻihaʻi alumini. Ua like ka EPDM me nā ʻāpana sila kiʻekiʻe ma muli o kona mau waiwai kino maikaʻi a me ke kūpaʻa ʻelemakule maikaʻi. I ka makahiki 2011, pili i ka aila honua a me nā kumu ʻē aʻe, ua piʻi ke kumu kūʻai o ka ethylene propylene, a hiki mai ka hoʻoilo o ka EPDM sealing strips, no laila ua hiki mai ka naʻauao Kina, ua hoʻomaka ka hoʻohana ʻana i ka lāʻau i hoʻohana ʻia i nā mea nui, a ua haunaele ka mākeke holoʻokoʻa. He paʻakikī ke loaʻa nā sila maikaʻi. Mea hana pani pani pani puka a me ka pukaaniani@门Window气气调板厂家 ʻO kekahi kalana ma Kina ke kumu o nā kaula hoʻopaʻa hale, a ma kahi o 70% o nā ʻāpana hoʻopaʻa hale EPDM o Kina mai kēia kalana. Aia kekahi luna ma ia ʻoihana hoʻokahi ma kēia kalana, a ʻo 70% o ka ethylene-propylene sealing strips o ka ʻāina i loaʻa mai iā mākou.
ʻAʻole ʻo ia ka mea hou loa no ka hoʻopaʻa paʻa ʻana i ka pahu silikoni, akā ʻaʻole. He mōʻaukala ʻo Silicone rubber ma Kina. ʻO nā mea hana pani pani puka a me ka puka makani ka mea punahele o ka lāʻau i nā makahiki i hala iho nei, a he palupalu loa lākou. I nā makahiki i hala iho nei, ua emi iki ke kumukūʻai, a ua hoʻohana mālie ʻia lākou i ke kūkulu ʻana i nā sila.
Ke hoʻohālikelike ʻia me ka ethylene-propylene rubber, ʻoi aku ka maikaʻi o ka silicone rubber no ka hoʻopaʻa ʻana he ʻoi aku ka maikaʻi o ka shrinkage a me ka deformation hana ma mua o ka ethylene-propylene rubber, no laila ʻoi aku ka maikaʻi o ka hana hoʻopaʻa ʻana, a mai ke kumu o ka hoʻohālikelike ʻana o ka manawa, hiki i ka silicone rubber ke kū i nā mahana a hiki i 300 ° C, a kū i ka ethylene-propylene rubber. ʻOi aku ka maikaʻi o ka 180 ° C. Ma lalo o ka mahana like, ʻoi aku ka lōʻihi o ke ola o ka silicone rubber ma mua o ka ethylene propylene rubber, a ʻoi aku ka lōʻihi o ke ola lawelawe. A loaʻa iā ia ka inertia physiological maikaʻi loa, non-toxic, tasteless, silicone rubber no hoʻi i ka wela maikaʻi loa, ke kūpaʻa anuanu, nā waiwai dielectric, ka pale ozone a me nā hana ʻē aʻe o ka lewa a me nā hana ʻē aʻe, ʻo ka hana koʻikoʻi o ka silicone rubber ka hoʻohana ʻana i ka wela ākea, hiki ke hoʻohana i ka puka a me ka puka makani sealing strip mea hana no ka manawa lōʻihi ma -60 ° C (a i ʻole ka wela haʻahaʻa) i +250 ° C (a i ʻole ke kiʻekiʻe o ka mahana). No laila ʻo ka silicone rubber kahi koho kūpono no ke kūkulu ʻana i nā sila i kēia au.
