He aha ka WPC (Wood-Plastic Composite)

Hoʻopili ʻia ka hui ʻana ma o nā ʻenehana hana plastic e like me extrusion, compression molding, a i ʻole injection molding e hana i nā papa a i ʻole profiles. Hoʻohana nui ʻia ʻo WPC i ke kūkulu ʻana, nā lako, ka pahu logistic, a me nā ʻoihana ʻē aʻe. ʻO ka mea kikoʻī, ʻo nā papa i hana ʻia e ka wela-extruding i hui ʻia o nā plastics a me ka palaoa lāʻau i nā ʻāpana kikoʻī ua kapa ʻia ʻo "extruded wood-plastic composite boards."

ʻO ka WPC nā waiwai i loaʻa mai kāna mau kumu kumu: polyethylene kiʻekiʻe (HDPE) a i ʻole polypropylene, i hui pū ʻia me nā fibers lāʻau, e hāʻawi ana iā ia me ka hui ʻana o ka plastic a me nā ʻano lāʻau.

ʻOi loa ka hiki ke hanaʻ
Mālama ʻo WPC i ka hiki ke hana e like me ka lāʻau—ʻo ka ʻeli, ke kui, a me ka hoʻolālā hiki ke hana me nā mea hana lāʻau maʻamau. ʻOi aku kona ikaika paʻa kui ma mua o nā mea synthetic ʻē aʻe, ʻoi aku ma mua o ko ka lāʻau maoli e 3 mau manawa a me ka particleboard e 5 mau manawa. ʻOi aku ka maikaʻi o kona ʻano mechanical i ka lāʻau.

Ikaika Kiekieʻ
Hāʻawi ka ʻāpana plastik iā WPC me ka modulus elastic maikaʻi. Hoʻohui pū ʻia me nā fiber i hoʻoikaika ʻia, loaʻa iā ia nā waiwai mechanical (e laʻa, ka ikaika compressive, flexural resistance) e like me ka lāʻau paʻa. ʻO ka paʻakikī o ka ʻili he 2-5 mau manawa ko ka lāʻau maoli.

Kūleʻa Wai, Kūleʻa Kūʻē, a me ke ola lōʻihiʻ
ʻAʻole like me ka lāʻau, pale ʻo WPC i nā ʻakika / kumu ikaika, ka wai, a me ka corrosion; ʻAʻole ia e hoʻohua i ka maʻi bacteria, kūʻē i ka nalo, a i ʻole ka poʻi. ʻOi aku kona ola ma mua o 50 mau makahiki.

Mea hiki ke hooponoponoʻ
Hiki i nā mea hoʻohui ke hiki i ka polymerization, ka hoʻoulu ʻana, ka mālama ʻana, a i ʻole ka hoʻololi ʻana i nā plastics, e ʻae ai i ka hoʻopilikino ʻana i ka mānoanoa, ikaika, a me nā hiʻohiʻona kūikawā o WPC (e laʻa, anti-aging, anti-static, flame-retardant).

UV Paʻa a me ka waihoʻoluʻuʻ
Hōʻike ʻo WPC i ka paʻa kukui ultraviolet (UV) maikaʻi a me ka paʻa kala.

Hoʻomau Kaiapuniʻ
ʻO kahi pōmaikaʻi nui, ʻo ia ka hiki ke hoʻololi i ka ʻōpala (e laʻa, nā mea kanu, nā plastic i hana hou ʻia) i huahana waiwai. Hiki ke hoʻohana hou ʻia ʻo WPC, decomposes me ka palekana, a pale i ka "pollution keʻokeʻo," e lilo ia i mea pili i ka kaiaola.

ʻNā Mea Maka ʻokoʻa

Hoʻokomo mua ʻia nā ʻāpana palaki i ka HDPE a i ʻole PP, ʻoiai ʻo nā mea lāʻau e hiki ke lilo i palaoa lāʻau, nā hull laiki, a i ʻole ka lāʻau. Hoʻohana pū ʻia nā mea hoʻohui liʻiliʻi a me nā mea hana.

ʻHoʻolālā Hoʻololiʻ
Hiki ke hoʻoheheʻe ʻia ka WPC i nā ʻano like ʻole a me nā nui e hoʻokō i nā pono kikoʻī.
