Nānā nā mea hana ʻeke sima i ka hana kikoʻī o nā ʻano maʻamau o nā ʻeke i ulana ʻia
1, kaumaha māmā
Maʻalahi ka maʻalahi o nā plastik, a ʻo ka mānoanoa o ka wili plastik ma kahi o 0, 9-0, 98 g/cm3. Hoʻohana maʻamau ka polypropylene braid. Inā ʻaʻole hoʻohui ʻia kahi mea hoʻopihapiha, ua like ia me ka nui o ka polypropylene. ʻO ka nui o ka polypropylene no nā noi ulana plastic he 0, 9-0, 91 grams no ke kenimika cubic. ʻOi aku ka māmā o nā braids ma mua o ka wai. ʻO ke kiʻekiʻe haʻihaʻi plastic braid he ʻano mea maʻalahi a haʻihaʻi kiʻekiʻe ka ikaika i nā huahana plastik, e pili ana i kona ʻano molekala, crystallinity, a me ke kuhikuhi ʻana. Ua pili pū i ke ʻano o nā mea hoʻohui. Inā hoʻohana ʻia ka ikaika kikoʻī (ikaika/kaumaha kikoʻī) no ke ana ʻana i ka wili plastik, ʻoi aku ka kiʻekiʻe a kokoke paha i ka mea metala a maikaʻi ke kūpaʻa kemika.
2, ka ulana ʻilika e kūʻē i nā mea ʻole
Loaʻa i ka mea organik ke kūpaʻa corrosion maikaʻi ma lalo o 110 degere Celsius a ʻaʻohe hopena iā ia no ka manawa lōʻihi. Loaʻa iā ia ke kūpaʻa kemika ikaika i nā solvents, grease, etc. Ke piʻi ka mahana, hiki i ka carbon tetrachloride, xylene, turpentine, etc. ke pehu. ʻO ka waika nitric fuming, ka ʻakika sulfuric fuming, nā mea halogen a me nā oxide ikaika ʻē aʻe e hoʻoheheʻe ʻia ia, a he kūpaʻa maikaʻi ʻo ia i nā alkalis ikaika a me nā ʻakika ākea.
3, maikaʻi abrasion kū'ē
He liʻiliʻi ke koena o ka friction ma waena o ka polypropylene plastic braid maʻemaʻe, ma kahi o 0 a i ʻole 12 wale nō, e like me ka nylon. I kekahi ʻano, he hopena lubricating ka friction ma waena o ka plastic braid a me nā mea ʻē aʻe.
4, maikaʻi uila insulation
ʻO ka polypropylene braid maʻemaʻe kahi mea hoʻokalakupua uila maikaʻi loa. No ka mea, ʻaʻole ia e komo i ka makū a ʻaʻole i hoʻopilikia ʻia e ka haʻahaʻa i ka lewa, ua kiʻekiʻe hoʻi ka puʻupuʻu haʻihaʻi. ʻO kona mau dielectric he 2, 2-2, a he kiʻekiʻe loa kona kūpaʻa leo. ʻAʻole i manaʻo ʻia ka insulation maikaʻi o ka plastic braiding e hoʻohana iā ia no ka hana ʻana. Hoʻohana i nā mea insulating.
5. Kū'ē kaiapuni
Ma ka lumi wela, ʻo ka lole i ulana ʻia i ka ʻiʻo ʻaʻole loa e hoʻoheheʻe ʻia, ʻoi aku ka haʻahaʻa o ka wai absorption i loko o 24 mau hola ma mua o 0, 01%, a he haʻahaʻa loa ke komo ʻana o ka wai. I nā haʻahaʻa haʻahaʻa, lilo ia i palupalu a palupalu. ʻAʻole e maloʻo ka ulana plastik.
6. Ke kūʻē ʻana i ka wā kahiko
ʻAʻole maikaʻi ke kūpaʻa ʻelemakule o ka braid plastic, ʻoi aku ka haʻahaʻa o ka braid polypropylene ma mua o ka polyethylene braid. ʻO nā kumu nui o kona ʻelemakule ʻo ka wela wela a me ka photodegradation. ʻO ka maikaʻi anti-aging maikaʻi o ka plastic braid kekahi o kāna mau hemahema nui, e pili ana i kona ola lawelawe a me nā wahi noi.
