Nā waiwai pepa polyethylene kaumaha molekala kiʻekiʻe loa

ʻO ka polyethylene kaumaha molekala kiʻekiʻe loa (UHMW-PE) kahi mea ʻenekinia thermoplastic e hoʻohui i nā pono āpau o nā plastics. Me ke kūpaʻa ʻana i ka ʻaʻahu, ke kūpaʻa hopena, ke kūpaʻa i ka corrosion kemika, kā lākou lubrication ponoʻī, ka coefficient pale ʻaʻahu haʻahaʻa haʻahaʻa he liʻiliʻi, ke kaumaha māmā, ka omo ikehu, ke kūpaʻa ʻelemakule, ka pale ahi, ka antistatic a me nā hana maikaʻi ʻē aʻe, ka hoʻohana ʻana i ka hale hana mana UHMW-PE, ka hale hana lanahu, ka hale hana coking lanahu; ʻOre a me nā silos mea ʻē aʻe o ka hale hana sima, ka hale hana kila a me ka hale hana alumini; ʻO ka palaoa, ka hānai, ka hale ʻoihana lāʻau lapaʻau, ka hale hoʻopaʻa uwapo, a pēlā aku, hiki ke pale i nā mea pipili, hoʻolalelale i ka wikiwiki o ka hānai ʻana, hoʻopau i ka ulia pōpilikia, mālama i ka hoʻopukapuka kālā a me ke kumukūʻai o ka pū ea, hiki i ka paʻa nui o ka lining ke pale aku i ka hoʻopili ʻana o ka pauka i ka paʻa a hoʻemi i ka pōʻino o ka hoʻouka ʻana a me ka hoʻokuʻu ʻana i nā mīkini i ka bulkhead. Me ka hoʻomohala ʻana o ka ʻenehana hana plastik, e ākea ka kahua noi o UHMW-PE.

ʻO A, ke kūpaʻa kiʻekiʻe o ke kapa komo, ma muli o kona ʻano molekala kūikawā, ʻoi aku ke kiʻekiʻe o ke kūpaʻa o ke kapa komo ma mua o nā huahana plastik metala maʻamau, 6.6 mau manawa o ke kila kalapona, 5.5 mau manawa o ke kila kila, 27.3 mau manawa o ke keleawe, 6 mau manawa o ka nylon, 5 mau manawa o ka ptfe;

B, hana lubrication ponoʻī maikaʻi, coefficient friction liʻiliʻi, kū'ē kahe liʻiliʻi, mālama ikehu;

C, ikaika hopena kiʻekiʻe, paʻakikī maikaʻi, ʻoiai ma ka mahana haʻahaʻa, ʻaʻole e haki i ka hopena ikaika;

D, kūpaʻa maikaʻi loa i ka palaho kemika, kū'ē (koe wale nō ka waikawa sulfuric i hoʻohuihui ʻia, ka waikawa nitric i hoʻohuihui ʻia, a me kekahi mau mea hana organik) aneane pau ka waikawa, alkali, a me ka paʻakai;

E, ʻaʻohe mea ʻawahia, ʻono ʻole, ʻaʻohe exudate;

F, nā waiwai uila maikaʻi, haʻahaʻa loa ka omo ʻana o ka wai;

ʻO G, kūpaʻa maikaʻi loa i ka haki ʻana o ke kaiapuni, 200 mau manawa o ka polyethylene maʻamau;

H, kūpaʻa haʻahaʻa maikaʻi loa, ʻaʻole palupalu ʻoiai ma -180C °.
