Ka poʻe hoʻohana pinepinePaipu PEʻike i ke kūkulu halePaipu PEHe laina like ka ili me ka waihoʻoluʻu like, uliuli, melemele, ʻulaʻula, no laila he aha ke ʻano?Ma ka mākeke paipu kūloko o Kina, ʻelua mau mākeke noi nui.PE chemical inoa Kina, polyethylene, PE mea ma muli o kona ikaika kiʻekiʻe, kiʻekiʻe wela kū'ē, corrosion kū'ē, non-toxic, aahu a me nā 'ano'ē aʻe, ua hoʻohana nui 'ia i loko o ke kahua o ka wai a me ka wai hana.No ka mea, ʻaʻole ia e ʻōpala, no laila he paipu kūpono ia e pani ai i ka paipu wai hao maʻamau;E like me kona hoʻohana ʻana, ʻike ʻia ka ʻili o ka paipu PE e nā laina hōʻailona kala like ʻole.ʻO nā waihoʻoluʻu e hōʻike ana i kekahi mau hoʻohana.
1.Laina kaha ʻulaʻula: PE mine paipu
Ma waena o nā plastics ʻenekinia āpau, ʻo ke kūpaʻa ʻana o ka HDPE e noho i ka lei o nā plastics, ʻike maka.ʻOi aku ke kiʻekiʻe o ke kaumaha molekala o ka mea, ʻoi aku ka ʻoi aku o ka ʻaʻahu, ʻoi aku ma mua o ka nui o nā mea metala (e like me ke kila kalapona, ke kila kila, ke keleawe, etc.).Ma lalo o ke kūlana o ka corrosion ikaika a me ka lole kiʻekiʻe, ʻo kona ola lawelawe he 4-6 mau manawa o ka paipu kila a me 9 mau manawa o ka polyethylene maʻamau.A hoʻomaikaʻi i ka pono o ka hoʻouna ʻana e 20%.
ʻO ka flame retardant, maikaʻi ka hana antistatic, kūpono nā mea āpau i nā koi maʻamau.ʻO ke ola lawelawe ʻo Downhole ma mua o 20 mau makahiki, ʻoi aku ka maikaʻi o ka hoʻokele waiwai, ka pale ʻana i ka hopena, ke kūpaʻa ʻana, ka hopena kūʻē pālua.
2.Laina polū:Paipu wai wai PE, paipu wai, a paipu ahi
ʻO ka paipu PE blowdown: ʻO ka paipu PE i hoʻohana ʻia no ka puhi ʻana i kapa ʻia ʻo polyethylene pipe kiʻekiʻe, ʻo ia ka HDPE ma ka ʻōlelo Pelekania.Hoʻohana pinepine ʻia kēia ʻano paipu e like me ka paipu ʻenekinia municipal, i hoʻohana nui ʻia ma: ʻoihana hoʻomaʻemaʻe wai.Ma muli o kona pale ʻana i ka ʻaʻahu, ka pale ʻana i ka waika, ka pale ʻana i ka corrosion, ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa kiʻekiʻe a me nā ʻano ʻē aʻe, ua hoʻololi mālie ʻo ia i ke kūlana o ka paipu kila kahiko, ka paipu sima a me nā paipu ʻē aʻe i ka mākeke, ʻoi aku ka māmā o ka paipu i loko. kaumaha a maʻalahi e hoʻouka a neʻe, ʻo ia ke koho maikaʻi loa o nā mea hou.
ʻO ka paipu wai wai PE: ʻO ka paipu PE no ka lako wai ka huahana pani o ka paipu kila kahiko a me ka paipu wai inu PVC.Pono ka paipu wai e hoʻokau i kekahi kaomi, koho maʻamau i ke kaumaha molecular kiʻekiʻe, ʻoi aku ka maikaʻi o nā waiwai mechanical o ka resin PE, e like me ka resin HDPE.ʻO ka resin LDPE he haʻahaʻa haʻahaʻa haʻahaʻa, haʻahaʻa haʻahaʻa haʻahaʻa, kūpaʻa maikaʻi ʻole, maikaʻi ʻole ke kūpaʻa ʻana i ka wā e hana ai a me ka hoʻoili ʻana, a me ka pilina paʻakikī, ʻaʻole kūpono ia e like me ke ʻano o ka paipu wai.Eia nō naʻe, ma muli o kāna helu olakino kiʻekiʻe, ua lilo ʻo PE, ʻoi aku ka HDPE resin, i mea maʻamau i ka hana ʻana i nā paipu wai inu.ʻO ka HDPE resin ka liʻiliʻi melt viscosity, ka wai maikaʻi a me ka hana maʻalahi, no laila ua ākea ka laulā koho o kāna helu hoʻoheheʻe, maʻamau MI ma waena o 0.3-3g / 10min.
3.Laina lepili melemele: paipu kinoea PE
ʻO ka paipu PE no ke kinoea ka huahana pani o ka paipu kila kahiko a me ke kinoea PVC.
Pono ka paipu kinoea e hoʻokau i kekahi kaomi, koho maʻamau i ke kaumaha molekala kiʻekiʻe, nā waiwai mechanical maikaʻi o ka resin PE, e like me ka resin HDPE.ʻO ka resin HDPE he haʻahaʻa haʻahaʻa haʻahaʻa, haʻahaʻa haʻahaʻa haʻahaʻa, paʻakikī paʻakikī, maikaʻi ʻole ke ʻano o ka hoʻokumu ʻana, a me ka pilina paʻakikī, ʻaʻole kūpono ia e like me ke ʻano o ka paipu wai.Eia nō naʻe, ua lilo ʻo LDPE, ʻoi aku ka LLDPE resin, i mea hoʻohana maʻamau no ka paipu kinoea ma muli o kāna helu olakino kiʻekiʻe.ʻO LDPE, LLDPE resin melt viscosity ka liʻiliʻi, ka wai maikaʻi, ka hana maʻalahi, no laila ke ākea ka laulā koho o kāna helu heheʻe, maʻamau MI ma waena o 0.3-3g / 10min.
