He aha i polyethylene? ? Iecaianoaaiiuo o polyethylene. Articles o polyethylene

Ma ka mōʻaukala o ka 'epekema, kekahi discoveries hiki mai ma ka ulia, a me ka mahaloia mea keia mea pinepine he he hopena ia o kekahi hana. Muli o kona kulana ma ka paha ka mea, uaʻike aniline make no fabrics, a haawi aku i ka hope? Aneiai, aʻanoʻenehana Ua Hopu i loko o ka consumer oihana puolo. hiki mai A like moʻolelo me ka polyethylene.

E wehewehe ana o ka mea

Ka mua hihia o ka? Iecaianoaaiiie o polyethylene iloko i ka 1898. I ka mehana-i o Kelemānia me Kinohi diamezotana chemist Hans av Pehman loaʻa i ka lalo o ka Tube mea,ʻaʻole he mea kupanaha aftertaste. Ka mea ua hala loa mānoanoa, a nana aku la e like nahaehae, nä känaka 'epekema nā hoapili kapa ia polimetillinom. Next wale i loko o keia pae ana o kānakaʻepekema i i kiʻi i ka hopena i aneane hoopoina, uku hoopanee, i kekahi i waho. Akā,ʻaʻole me ka manaʻo kaulia i loko o ka lewa, e noi ana i ka pragmatic kokoke loa i kahi. I ka mea i hiki mai ai, i loko o kanakolu-ōlaʻi makahiki, polyethylene i ua hou-wehe like me ka kaulele huahana o ka pilikia ka hoʻokolohua.

Ka Beritania lalau aku la ia, a lawe pio

Hoikehonua, polyethylene mea i hanau ma ka keʻena hoʻokolohua imperial Nine na hana oʻEnelani. E. Fawcett a me R. Gibson alakai ho okolohua me ka kiʻekiʻe a me ka haahaa puʻe kinoea, a hoʻomaopopo i kekahi o nā aka wahi nō, i mālama 'ia ia mea ma ka a, uhi me ka ike ole waxy waiwai. Me ka hana maluʻaoʻao kanawai, ka mea i ho'āʻo mau e loaa ka waiwai, akā, i ole no kuʻu kaumaha.

Synthesize pīlali mahope o M. Perrin, he limahana o ka ia poʻe i loko o nā makahiki. Ua i ka mea nana i hana i ka 'ike loea hou i hana i ke kumu no ka hanalima? Iecaianoaaiiie o polyethylene. Nā waiwai a me ka pono o ka mea e lauwili wale ma ke ana likeʻole catalysts. Ka nuipa a polyethylene? Iecaianoaaiiuo hoomaka i ka 1938, a me ka mea i Palapala Sila Nui i ka 1936.

maka mea

Polyethylene - he paa pīlali i keʻokeʻo ano. Ua pili ia i ka papa no ke aloha i huiʻia. He aha i polyethylene? Ka maka mea no kona hoomalolo mea'etolina kinoea. Kinoea polymerized ma kiʻekiʻe a me ka haahaa puʻe ua loaa i ka auoiaea hānai pellets no ka hou ana. No kekahi keʻano o ka hanaʻana polyethylene ua hua mai i loko o ka lepo palapala.

I ka papa kuhikuhiE ano o

I ka lā, i ka pīlali ua hua mai i nā walaʻauʻana papa o ka LDPE a me PNP. Material i ma ka awelika puʻe o ka pili hou hana mea hou i hana muaʻole, akā, i loko o ka lōʻihi makahiki helu o ka hookuu huahana e ulu kūpono ma ka pili me ka hoʻomaikaʻi 'ano a me ka laulā kahua o ka palapala noi.

No ka kalepa ana, me ka hahai ana i ke ano o ka mea (papa):

• Low nuʻa a he okoa ka inoa - ke kiʻekiʻe-puʻe (HDPE, LDPE).
• High-pa apŘ a haahaa puʻe (LDPE LDPE).
• Laina polyethylene, a polyethylene meakino puʻe.

Aia nō 'ē aʻe ke ano o ka polyethylene, kela mea keia mea o ka a i kona mau waiwai a me ke kahua o ka palapala noi. Ke particulate pīlali i loko o ka? Iecaianoaaiiie kaʻina e pākuʻi likeʻole colorants e hiki ai e loaa i kaʻeleʻele polyethylene, ulaula a me kekahi 'ē waihoʻoluʻu.

JHA

? Iecaianoaaiiuo o polyethylene ua hana i loko o ka Nine Inch oihana puolo. Kinoea'etolina - walaʻauʻana hehee ai (o i e polyethylene), akā,ʻaʻole ka mea wale kekahi koi 'ia e loaaʻi ka mea.

Makaukau o HDPE ia lŘlŘ ma autoclaves, omo reactors. LDPE papa ua hanaʻia i loko o ka autoclave, e like me ka State Koo, ma laila nō ewalu. loaa he iwakalua-kekahi 'ano o ka kiʻekiʻe-pa apŘ polyethylene mai ka omo mīkini'ātoma.

No ka mea hoʻololi kemikala o PVP koi 'ia e like me ka mea ma lalo nei:

• Mahana huahelu - mai ka 200 a hiki i 250 ° C.
• Hōʻeleu - maemae oxygen, peroxide (aloha).
• Puʻe o ka 150 a hiki i 300 MPa.

Poimerizirovannaya kaumaha i loko o ka pae mua mai i ka kinowai moku'āina, a laila, kolo ana i ka separator, i hoakaka ia ka granulator, ma ka mōlina mea o ka hoʻopau 'ana i granules.

LDPE kona mea e like hoʻohana no ka? Iecaianoaaiiie o ka'ōpala Film, termoplenok, multilayer'ōpala. No hoi kiʻekiʻe-pa apŘ polyethylene hoʻohana ma o ka kaʻa, Nine Inch a me ka ai na hana. No ka mea,ʻo kiʻekiʻe-kbps mau nōʻohe i hoʻohana i loko o ka hale noho kaiaulu.

laina polyethylene

He aha hana i kekahi meakino-puʻe polyethylene paha laina polyethylene?

• Ka paio hahana maoli nō mahana mai i 120 ° C.
• Aaeei puʻe i 4 MPa.
• Stimulator kaʻina - hōʻeleu (Ziegler-Natta hōʻeleu me ka läÿau, o ka titanium koloriside hui melalloorganicheskim).

Ke kaʻina Ua pu ma kimu o polyethylene i loko o ka palapala o ka flakes, a i laila kaawale mai ke kaʻina hana pāʻoihana, ukali ma granulation.

Kēiaʻano o ka polyethylene ua wehewehe aku ma ka pa apŘ kiʻekiʻe, wela ia'ku a me ka waimaka. Ka poepoe o ka palapala noi i nāʻano likeʻole o ka'ōpala Film, a me wela iie mea / nā huahana. O granular mea o ka pīlaliʻano ua hanaʻia māhele no ka hoolei ana i nui machines, hō'īpale kumuhana, kiʻekiʻe ikaika paipu, consumer waiwai , a pela aku.

High nuʻa polyethylene

ANP i ekolu manufacturing hana. Ka hapanui o poʻe hana i ka hana o ka "wehe 'polymerization". Ke kaʻina hana o ka loaa ana EOR mākaukau kaua paha pili i slurry a me ka ikaika aku manaʻo pīhoihoi o ka feedstock, ka hōʻeleu ua koi 'ia e hoʻomaka i ke kaʻina hana.

Ka lua o ka loa e like me ka hana o ka? Iecaianoaaiiuo mea he kākoʻo pāʻoihana polymerisation ma lalo o ka aoao o ka mahana a me ka hōʻeleu komo. Ka papa hana mea ole loa efficient, mai i ka polymerization ka hōʻeleu ua reacted a me ke kūpono pīlali haalele i kekahi o kona ano.

I ka hope o ka? Iecaianoaaiiuo kiʻina hana o ka PNP kinoea pae polymerization, ka mea, ua kokoke e hele, akā, i kekahi manawa ia lŘlŘ i loko o kekahi mau mea kanu. Ke kaʻina hana i wahi ma ka hoʻohuihui i ka maka mea kinoea pae ma lalo o ka aoao o ka maholahune. Ka pīlali hope ua loaa ia me ka nonuniform 'ole a me ka pa apŘ, a e loli ai i ka mea e like ai o ka hoʻopau' ana i huahana.

? Iecaianoaaiiuo o HDPE ia lŘlŘ ka kēia pololei iloko o:

• Ka wela Ua mālama 'ia ma, mai 120 ° C i 150 ° C.
• Puʻe E ole oi 2 MPa.
• Polymerization catalysts (Ziegler-Natta hōʻeleu me ka läÿau, o ka titanium koloriside hui melalloorganicheskim).

A lako e o keia manufacturing iaoiaeii ua wehewehe aku ma ka rigidity, kiʻekiʻe nuʻa, haahaa elasticity. No laila, i ka laulā o kona palapala noi, he hana mau. Kōmike polyethylene hoʻohana no ka? Iecaianoaaiiuo o ka nui-nui pahu waihona me ka kiʻekiʻe ikaika ano. Koi i loko o ka hana hana, Nine Inch hana, no ka mea? Iecaianoaaiiie o consumer waiwai, aneane oia aole i pili.

waiwai

Polyethylene Ua hoʻopale i ka wai, a hiki i na ano o nā'uheheʻe, nāʻakika (ke aloha,'okanikaʻole), 'aʻole i pane koke me ka paʻakai. Ma'ā kī ana i kekahi ala o ke paraffin, aia no he glow uliuli tint, uuku ke ahi. Decomposition ia lŘlŘ ka wā kokoke ana i nitricʻakika, chlorine a me fluorine i loko o ka gaseous a me ke kinowai ai moku'āina. Me ka poe oo hoi, a ia lŘlŘ ma ka lewa, e hana i ka mea keʻa-loulou ma waena o hakakino nā kaula hao, e ka lako e brittle, crumbly.

consumer kona mea e like

Polyethylene - He wahi kū hoʻokahi mea mau i loko o ka hale a me ka wahiʻoihana. Ua mea olelo lealea i ka awelike consumer e e hiki ke hooholo me ka nui o na mea mai no ia i kona maka i kela la. Ke global hookuu polymers polyethylene i kaʻana like 'ana i ka liona ka o ka makeke - 31% o ka heluna loa wahi lulu huahana.

Ke kaumaha ma muli, a ua i mai o polyethylene a me ka enehana? Iecaianoaaiiie, kona mea e like ai i kona manao. Ua lako e hoʻohui i kekahi manawa kue ano: kohoʻia a me ka ikaika, a me ka ductility toughness, ikaika tensile a me ka waimaka ia'ku, ia'ku iʻano pākīkē hana kūpono a me ka liluwelo konohiki. I ka maʻamau o ke ola, ua hana nā pākeke o kekahi pa apŘ, disposable tableware, ea papale, māhele o ka hale nā mīkini home, a oi.

noi

Noi o ka polyethylene huahana ua i kaupalena ', i kekahi hana a kanaka hana pu aku i kēia mau kiʻi:

• Ka loa hoʻomano hoʻohana pīlali i loaa i loko o ka hana o ka'ōpala mea. Ma keia hapa o ka palapala noi, ua kupono e pili ana i 35% o ka maka mea i lawe. Oia hoʻohana ua hoaponoia gryazeootalkivayuschimi waiwai, nele o ka hoomalu ana no ka mea ikea o ka fungus a me microorganisms. Kekahi o ka laki loaʻa - he ea lole, a he ākea palapala noi. E loli iki ana i ka lōʻihi o kona manao, o ka mea hoʻohana ua kaupalena ma ka laula o ka AEeAaOA wale.
• Me ia ma ka naau, mai i ua i polyethylene, ka mea i ike ke kumu i lilo hanohano e like me kekahi o ka maikaʻi hō'īpale pono hana. Kekahi o kona imi-hope ano ma keia wahi i ka nele o ka uila conductivity. I paʻa mau wai repellency ka waiwai, a i ua hoʻohana ma o ka? Iecaianoaaiiie o waterproofing mea.
• Ia'ku i ka mea luku ikaika o ka wai me ka'ūheheʻe, mau hiʻohiʻona nō e paka na ohe i ka polyethylene no ka hale a me ka hanalima nā mea kūʻai mai.
• Ma ka hana ka hana i ka pono o ke kani'īpale o polyethylene hoʻohana, kona haʻahaʻa thermal conductivity. I kŰia mau mea e pono keia mau mea i loko o ka hana ma luna o kona kumu noi no thermal'īpale o ka noho a me ka hanalima hale. Polyethylene ua hoʻohana 'ia no ka oaoieei-'īpale o ka paio hahana maoli nō ka papa kuhikuhiE ma ÿole mechanical' enekinia, a no laila, ma luna o.

Nā Papahana O Ka aaioee

Ke kaumaha ma muli o ka ano ma i ka granular maka mea i hoʻokō 'ia e hilinaʻi ma luna a momoku ahi o ka polyethylene ua loaa. Common aoao:

• Extrusion (extrusion). Ua ua hoʻohana 'ia no ka hana o kaʻohe, a me ka'ōpala me ke ano o ka ho film, kuina nā no ka kūkuluʻia a me nā mea hoʻonani, manufacturing uwea, i ea kaukini loloa a me nā huahana.
• Mōlina, thermo-holo ho okumu i kaʻina. ʻano nui hoʻohana no ka manufacturing'ōpala kumuhana, poho etc.
• Extrusion e hoʻokani mōlina, rotational. Ma keia hana ua loaa ia volumetric nona iho, he nui'ōpala pahu.
• Kilo. No ka 'ike loea hou kekahi i loko o ka hana nuipa a polyethylene kau iho la ka ikaika oihana mua (metala) e i kekahi kūkuluʻia o ka mahuahua ikaika, akā, me ka emi kāki.
