HDPE sɛbɛn bɛ a yɛrɛ bonya ni fanga caman ye, ka sɔgɔsɔgɔ, ka sɔgɔli kɛ, ani ka impact resistance, ka sɔrɔ fana a ka nɔgɔn ani a baara ka nɔgɔn, o b’a kɛ fɛn ye min nafa ka bon kosɛbɛ bi iziniw kɔnɔ.
Material Propriétés .
1. Mekaniki jogo ɲumanw .
HDPE sɛbɛn bɛ ni density (dansi) ye (a ka c’a la, a bɛ 0,94 ni 0,97 g/cm3 cɛ), o bɛ na ni tensile (janya) ni compression (dafalen) fanga ɲuman ye. A kɔgɔjida la gɛlɛya, a ka c’a la 50 ni 60 cɛ, o b’a to a bɛ se ka sigicogo sabatili sabati hali kɛnɛma fanga nafamaw kɔrɔ. A bɛnnen don baarakɛcogo ma min bɛ kɛ ni sɛgɛnba ye, i n’a fɔ fɛnw lasecogo ani masinw.
2. Kimiya sabatili ɲumanba .
HDPE sɛbɛn bɛ se ka asidi caman, alkali, kɔgɔw ani fɛnɲɛnamafagalanw kɛlɛcogo ɲuman jira, o b’a to a tɛ-A bɛ se ka kɛ. O la, a bɛ kɛ ka caya kemikɛli ni sigida lakanani baarakɛyɔrɔw la, minnu bɛ kɛ ka pankurunw datugu, ka pibilikiw labɛn, ani ka baara wɛrɛw kɛ. Hali kemikoro sigida gɛlɛnw na, HDPE sɛbɛn bɛ waati jan{3}}term sabatilen mara.
3. Coefficient de friction low et être resistance .
HDPE Sheet ka surface smooth ani low coefficient de friction (a bɛ se ka kɛ 0,05-0.1 ye) kɛ sugandili ɲuman ye ka ɲɛsin ɲɔgɔnkanu baarakɛcogo ma i n’a fɔ sliders, guide rails, ani bearings. Ka fara o kan, a sɛgɛnbaliya bɛ tɛmɛ plastiki gansanw ta kan, ka minɛnw ɲɛnamaya janya kosɛbɛ ani ka dɔ bɔ ladonni musakaw la.
4. Lamini degunw ka kari .
HDPE sɛbɛn bɛ sigida degunw ka fɛnɲɛnamafagalanw (ESCR) jira. Hali ni UV fiɲɛ, oksidanw, walima funteni jugumanba kɔfɛ, a bɛ gɛlɛya ɲuman mara ani a bɛ tiɲɛni walima a karili kunbɛn.
5. A ka nɔgɔn ani a bɛ se ka baara kɛ nɔgɔya la .
Ni an y’a suma ni laadalafɛnw ye i n’a fɔ nɛgɛ, HDPE sɛbɛn ka dɔgɔn wa a ka nɔgɔn, o b’a to a tali n’a sigili ka nɔgɔn. A bɛ se ka baara kɛ fana ni tigɛ, jirituru, welding ani thermoforming ye walasa ka izini suguya caman magoɲɛfɛnw ɲɛnabɔ.
Aplikasi kunbabaw .
1. Industriw ka fɛn dilanni .
HDPE sɛbɛn bɛ baara kɛ kosɛbɛ masinw dilanni baara la, i n’a fɔ masinw ɲɛminɛbagaw, girinw, ani sigilanw. A sɛgɛnbaliya ni a yɛrɛ ka-Lubrifier properties bɛ dɔ bɔ friction bɔnɛ na ani ka minɛnw ka baarakɛcogo ɲɛ. Ka fara o kan, minɛnko ni nɛgɛko la, HDPE sɛbɛn bɛ kɛ sɛgɛn ye- min bɛ se ka fɛnw tanga fɛnw ma minnu bɛ se ka fɛnw sɔgɔ ani ka u sɔgɔ.
2. Kimi ni sigida lakanani .
K’a sababu kɛ a ka sɔgɔli kɛcogo ɲuman ye, HDPE sɛbɛn bɛ kɛ ka caya kemikɛlifɛnw marayɔrɔw la, reactor linings, acide ani alkali tanks, ani minɛn wɛrɛw walasa ka kemikaliya sɔgɔli bali nɛgɛ minɛnw kan. Lamini lakanani yɔrɔ la, HDPE sɛbɛn bɛ se ka kɛ nɔgɔ furakɛli minɛnw jɔcogo yɔrɔw la, i n’a fɔ jirisunw ni datugulanw, wa a bɛ waati ni kɔrɔya kunbɛncogo ɲuman sɔrɔ.
3. So jɔli ni siwili injiniyɛri .
So jɔli baara la, HDPE sɛbɛn bɛ se ka baara kɛ ni anti-slip duguma, jibolisira datugulanw, ani mankan tɛ minnu na kogow la ka da a ka anti-slip, corrosion resistance, ani saniya nɔgɔya kan. Siwili baara la, HDPE sɛbɛnw fana bɛ kɛ du kɔnɔ ji marayɔrɔw la, denmisɛnw ka tulonkɛfɛnw ani fɛn wɛrɛw. U farati tɛ, u tɛ-toxic ye, ani u bɛ dumuni dafa-Baarakɛcogo la.
4. Bololabaara ni fɛnw ladonni .
Bololabaara siratigɛ la, HDPE sɛbɛnw bɛ se ka kɛ nɛgɛso tɛmɛsira ye ani bolifɛnw tiɲɛni barikaw, k’a sababu kɛ u ka nɔgɔya n’u ka nɔ bilali ye- Logistiki baara la, palɛtiw ni fɛnw jiginni kɛsu minnu dilannen don ni HDPE sɛbɛnw ye, olu bɛ se ka tiɲɛ- bɛ se ka kɛ fɛn ye min bɛ se ka kɛ fɛn ye min bɛ se ka kɛ fɛn ye min bɛ se ka fɛnw mara ani ka u saniya, o bɛ kɛ sababu ye ka fɛnw mara ani ka taa ni u ye iziniw kɔnɔ i n’a fɔ dumuni ni furaw.
Yiriwali nataw taabolo .
Ni ɲɛtaa bɛ sɔrɔ fɛnw dɔnniya la, HDPE sɛbɛnw baara bɛ ka ɲɛ ka taa a fɛ. Misali la, barikalanw farali i n’a fɔ fibre carbone ani gilasi fiyɛ, o bɛ dɔ fara u fanga n’u ka funteni kan. O waati kelen na, sigida lakanani min bɛ ka bonya, o bɛ ka HDPE sɛbɛnw labɛn ka ɲɛsin fɛnw ma minnu bɛ se ka segin ka kɛ fɛn wɛrɛw ye ani minnu bɛ se ka tiɲɛ, walasa ka yiriwali sabatili magow ɲɛ. Don nataw la, HDPE sɛbɛnw bɛna kɛ hali baarakɛcogo jigiyaw ye minnu ka bon kosɛbɛ sanfɛ{3}}End forow la, i n’a fɔ fanga kura ani aerospace.
K’a sababu kɛ a ka baara kɛcogo ɲuman ye ani a bɛ se ka baara kɛ cogo min na, HDPE sɛbɛnw kɛra fɛn nafamaba ye bi iziniw ni siwili baarakɛcogo la. A kɛra sɔgɔli ye, a bɛ sɛgɛn, a jɔli ka nɔgɔn, walima a baara nɔgɔya, HDPE sɛbɛnw bɛ nafa caman di. Ni fɛɛrɛ kuraw bɛ ka taa ɲɛ, HDPE pankurunw ka baarakɛcogo bɛna bonya ka taa a fɛ, ka fɛɛrɛw di minnu bɛ se ka kɛ ka ɲɛ ani minnu bɛ se ka da u kan, izini suguya caman na.
