No ke aha ka lāʻaupaipa kaʻahe laina wili naylon?
Ke hoʻohana nei i ka nylon interlayer a me ka chlorinated butyl rubber ma ke ʻano o ka papa o loko a me waho, hiki ke hana i kahi ʻano hose hou e pale ai i ka leakage freon, e hoʻoikaika i ka paipu.
ʻO nā kumu kahiko o ka Rubber:
1. Oxygen: Oxygen i loko o ka lāʻau lapaʻau me nā molekala i loko o ke kaulahao radical manuahi, molecular chain break a excessive crosslinking, ka hopena i ka hoʻololi ʻana o nā waiwai lāʻau.
2. Ozone: Ozone kemika hana ma mua o oxygen ua oi aku ka kiʻekiʻe, oi luku aku, ka mea no hoi e uhai i ke kaulahao mole, akā, o ka hana o ka ozone ma ka hili me ka lāʻau deformation okoa.
3. Heat: E hoʻomaikaʻi i ka hoʻoheheʻe ʻana o ka oxygen a me ka hoʻoulu ʻana i ka oxidation reaction, i mea e hoʻolalelale ai i ka nui o ka hopena o ka lāʻau oxidation, ʻo ia ka mea maʻamau o ka wā kahiko - thermal oxygen aging.
4. Māmā: ʻO ka pōkole o ka nalu māmā, ʻoi aku ka ikaika. ʻO ia ka ultraviolet ikehu kiʻekiʻe e hoʻopau i ka lāʻau. Ma waho aʻe o ka hana pololei ʻana i ka haʻihaʻi a me ka hoʻopili ʻana i nā kaulahao mole kalapona, hoʻomoʻa ka lāʻau i ka ikehu māmā a hana i nā radical manuahi, ka mea e hoʻomaka a e hoʻolalelale i ke kaʻina hana o ke kaulahao oxidation, i kapa ʻia ʻo "light outer layer crack".
5. ʻO ka wai: ʻelua mau ʻano ka hana o ka wai: ʻo ka ʻōpala i ka ua ea wai a i ʻole i ka wai, maʻalahi e luku, ʻo ia ke kumu o nā mea hiki ke hoʻoheheʻe ʻia i ka wai i loko o nā pūʻulu a me nā hui hydrophilic a me nā mea ʻē aʻe e ka hoʻoheheʻe wai a me ka dissolution, hydrolysis a absorption a me nā kumu ʻē aʻe. Ma lalo o ka hopena o ka hoʻoheheʻe ʻana i ka wai a me ka ʻike lewa, e wikiwiki ka luku ʻana i ka lāʻau. Eia nō naʻe, i kekahi mau hihia, ʻaʻole e hoʻopau ka wai i ka lāʻau, a loaʻa nō hoʻi ka hopena o ka hoʻopaneʻe ʻana i ka ʻelemakule.
7. Aila: I ka hoʻohanaʻana i ke kaʻina hana o ka pilina lōʻihi me kaʻaila hinu, hiki i kaʻaila ke komo i loko o ka pahu e hoʻohū ai, e hopena i ka ho'ēmiʻana i ka ikaika o kaʻaila a me nā mea mechanical'ē aʻe. Hiki i ka aila ke hoʻohūhū i ka lāʻau, no ka mea, i loko o ka ʻaila, hoʻopuka i ka molecular diffusion, no laila e hoʻololi ke ʻano o ka ʻoihana vulcanized.
