HDPE barika ka bon, a ka nɔgɔn, a bɛ se ka kemikaliya ni a nɔfɛkow kɛlɛ. A musaka ka dɔgɔ, a bɛ se ka segin a cogo kɔrɔ la, wa a dilanni ka nɔgɔn ka kɛ cogoya gɛlɛnw ye, o b’a to a ka ɲi kosɛbɛ iziniw ni feerekɛlaw ka baara caman na.
3. HDPE ka funteni hakɛ min bɛ fɔ pikiri kɛli waati la, o ye mun ye?
HDPE ka funteni hakɛ ɲuman pikiri kɛli la, a ka c’a la, o bɛ bɔ 246°C la ka se 280°C ma. O bɛ kɛ sababu ye ka jibɔ nɔgɔya ani ka fɛnw tiɲɛni bali.
4. HDPE bɛ se ka suma ni plastiki wɛrɛw ye cogo di i n’a fɔ poliporopilini (PP) walima PVC?
HDPE bɛ fanga ni nɔ bilali kunbɛncogo caman di ni i ye a suma ni PP ye, nka a tɛ se ka wuli ka bɔ a nɔ na. Ni aw ye a suma ni PVC ye, HDPE bɛ se ka wuli ka bɔ a nɔ na ani ka sigida lakana ka da a kan a bɛ se ka segin a cogo kɔrɔ la ani a kɔfɛfɛnw ka dɔgɔn.
5. Yala HDPE bɛ se ka segin ka kɛ fɛn wɛrɛ ye wa?
Ɔwɔ, HDPE bɛ se ka segin a cogo kɔrɔ la. A bɛ se ka segin ka kɛ HDPE (RHDPE) ye min bɛ segin ka kɛ fɛn kuraw ye, ka sɔrɔ ka fɛn kuraw dilan, ka tiɲɛniw dɔgɔya ani ka npogotigininw mago ɲɛ.
6. HDPE pikiri kɛcogo caman ye mun ye?
HDPE bɛ kɛ ka fɛn caman dilan, i n’a fɔ minɛnw, tulonkɛfɛnw, mobili yɔrɔw, jɔlifɛnw, ani pibilikiw ka da a kan a bɛ se ka kɛ cogo min na ani a bɛ se ka muɲu.
7. HDPE pikiri kɛcogo gɛlɛyaw ye jumɛnw ye?
Gɛlɛyaw ye a ka dɔgɔyali hakɛ caman ɲɛnabɔli ye, a bɛ mɔli kɛcogo ɲuman sabati walasa ka warping bali, ani ka gɛlɛya siri a la k’a sababu kɛ a ka dugukolo sanfɛla fanga dɔgɔyali ye, o bɛ a ɲini ka nɛgɛ kɛrɛnkɛrɛnnenw walima welding kɛ.
Kuncɛli: HDPE pikiri kɛcogo nata .
HDPE Injection Molding bɛ nafa caman di iziniw kɔnɔ. A fanga, a ka kemikaliya, ani a ka segin-ka-bɔ, o b’a kɛ sugandiliba ye dilanbagaw bolo. O kɛcogo bɛ se ka kɛ fɛn caman ye, a musaka ka dɔgɔ, wa a bɛ sigida lakana. Ko nataw HDPE dilanni na, olu bɛ sinsin sabatili kan. Bio-based HDPE ani reclushing techniques bɛ ka sɔrɔ ka sɔrɔ. Baarakɛcogo ɲɛtaa fana bɛ ka fɛn dilannenw jogo bonya ani ka tiɲɛniw dɔgɔya. Kuncɛli la, HDPE pikiri kɛcogo bɛ dannaya ni kokuradonni fara ɲɔgɔn kan. A bɛ sisan magow ɲɛ k’a sɔrɔ a bɛ ladamu gɛlɛya nataw la. Industri caman fɛ, a bɛ to sugandili hakilitigi ye, min bɛ sabati.
