Polyethylene - he Nine Inch waiwai a mea he lei o ka kalapona nā'ātoma, kela mea keia mea o ka i pili i nā nā lātoma o ka hydrogen. I loko nō o ka alo ana o ka haku mele 'ia, akā, ma laila nō nā wale nō. ka mea, oko i loko o kā lākou 'ole, a, nolaila, waiwai. Ka mea mua o ka laina kaulahao ma i ka degere o ka polymerization aku i ka 'inideka o elima tausani. Ka lua o ka 'ole - he ai manamana ai o 4-6 kalapona nā'ātoma mea e pili ana i ka papa kuhikuhiE kaulahao ma ka ākeʻakeʻa kumu hana. E like me ka outline loaa mai ma ka laina polyethylene? Keia ua loaʻa ma ka hoʻohana 'ana o kūikawā catalysts, a aloha ia ka polyolefins ma lōpū Mahana O Ke Kai (i ka 150 kekelē Kelekia ma) a me ka puʻe (mai i ka 20 me ka lewa). Akā, he aha ka mea? Mākou i kona Nine Inch ka waiwai, a me ka mea i laila, kāohi?

He aha ka mea?

Polyethylene - he thermoplastic pīlali, ma i crystallization kaʻina ua hana i ka wela o ka emi o ka hua 60 kekelē Kelekia. Ia mea i moakaka ia ma ka ahu iho manoanoa ua i pulu loa ma ka wai, ke aloha nā'uheheʻe i mehana ea ua i loli. Inā ka mahana aku i 80 kekelē Kelekia ma, i ka nani ua lawe mai mua, a laila, palaho i ka onaona hydrocarbons a me halogen nā mea loaʻa. Polyethylene - he waiwai i ka mea, pale adverse ole pāʻoihana o nāʻakika, paʻakai, a alkalis. Akā, inā i ka mahana aku i 60 kekelē Kelekia ma, ka mea hiki loa koke hoʻohiolo nō ia i nitric a me sulfuric nāʻakika. No ka ponaʻana polyethylene huahana ka mea, i ke ke hoʻokō 'oxidants, ukali ma ka noi o ka mea waiwai.

Pehea o ke? Iecaianoaaiiie o polyethylene?

No keia mea:

• Ano o ka kiʻekiʻe-puʻe (haʻahaʻa nuʻa). Polyethylene ua hana ma kiʻekiʻe puʻe, i mea ma ka laulā, mai 1 000 a hiki i 3, 000 me ka lewa ma ka wela o ka 180 kekelē Kelekia. Like o oxygen hana me ka initiator.
• Ano O haʻahaʻa puʻe (kiʻekiʻe nuʻa). Ma keia hihia, polyethylene ua hanaia ma ka manaʻo koikoi i mea ma ka liʻiliʻi loa elima me ka lewa, a me ka wela o ka 80 kekelē Kelekia ma ka hoʻohana 'ana i ke aloha'ūheheʻe a me Ziegler-Natta catalysts.
• A kaawale ka laina polyethylene-i? Iecaianoaaiiuo kalapona, haawi ia i luna. He waena ma waena o mua a me ka lua o ka heluʻai.

It E e kaulana i keia mea,ʻaʻole i nā 'ike loea hou wale i mea i hoʻohana. No laila, he pono ole, a oi o ka hoʻohana 'ana o ka metallocene catalysts. Ke ano o keia 'ike loea hou ka mea ma ka mea loaʻa nui ke kaumaha o ka pīlali, pela mahuahua ai ka ikaika o ka huahana. Ke kaumaha ma muli o ka 'ano o nā hale a me ka waiwai e pono ai ka wā hoʻohana' ana i ka lātoma, a ua hoʻohana 'ia e koho i kekahi ano o ka? Eaia. No hoi, ka mea e ho ololi i ka mahele heheʻe i ka mahana koi, mea paʻa, paakiki a me ka pa apŘ.

No ke aha lā i loaʻa mea he ikaika okoa?

Ke kumu nui no na oko o ka waiwai - ia ai manamana macromolecules. Penei, o ka nui ia mea, i ka lalo a me luna crystallinity pīlali elasticity. No ke aha lā i kēiaʻano nui? Ka nui, e hoike ana i ke ÿano o ka waiwai polyethylene e ulu ana a me kona pa apŘ a me ka hakakino kaupaona. E ka nana aku i ka hoopoina koke ana hoʻohālike. Ke polyethylene kuina he nui rigidity a me ka mäliko. Akā, ināʻoe e hoʻohana haʻahaʻa-pa apŘ iaoia, ke kūpono i nā puke e i kŘpa a maikai kohoʻia a me ka piliʻike pono ma ia. No ke aha la i mea hua mai la ia i ka e lauwili huahelu? Aie i ka oko ao ma ka pae'ōnaehana ana. No ka laʻana, polyethylene Makuakane me ka hawewe wahie. He pū tolerates hau. Ka pae'ōnaehana mahana huahelu o keia mea - mai ka -70 a hiki i +60 Kelekia. ʻOiai kanaka A hehi ihola au i hakuloli no i kekahi mau mea okoaʻano piʻina - a mai -120 hiki i +100. Keia ua 'ole ma o ka pa apŘ o ke polyethylene a me kona' ole ma o ka hakakino kiʻekiʻe.

Ke specificity o ka mea

It E e kaulana kekahi drawback - ka kokololio poe oo hoi o ka polyethylene. Akā, i kēia ua hikiwawe e ola ai. Hoomahuahua ae la lakou hana ola ua loaʻa ma kūikawā mea hoʻonui, antioxidants, i loko o ke kūlana a hiki hana kalaponaʻeleʻele, phenols paha amines. It e kaulana e hoi, nae, i ka mea haʻahaʻa-pa apŘ mea h ÷ alo alo, e ka mea maʻalahi ia e hoʻokō 'ia i loko o huahana. Not e hōʻike, a me nā pou waiwai. Polyethylene no ka mea, o ka pili-Polar pīlali mea he kiʻekiʻe kbps kiʻekiʻe-alapine (frequency) dielectric. No ka mea, o keia mau, a me keia poho tangent ma iki hoʻololi humidity loli, ana wela (ma ka laulā -80 i +100) a me ke alapine (frequency) o ka pila nui kahua. Here mākou e hoailona oukou i kekahi hiʻona. Penei, ina ma ka polyethylene i hōʻeleu residues, e hoʻokāʻoi aʻe ana i ka dielectric poho tangent, a hiki aku i ka kekahi mea hōʻemi o hō'īpale waiwai. Ua pono, e ano o ka nohona ma kulana i nānā 'mākou. Ano, e ka hoʻolohe i Kekahi Mau '.

He aha mea kiʻekiʻe nuʻa polyethylene?

Kēia laholio kukui crystallizable mea nona ka wela ia'ku mea i loko o ka laulā mai -80 a hiki i +100 kekelē Kelekia. Ua loaʻa he ka lā'ī ili. Vitrification hoʻomaka ma -20. A mahele heheʻe i ka - ma ka laulā 120-135. Ano o ka maikai hopena ikaika a me ka wela e kū'ē'ē mai. nuʻa polyethylene me ka nui loa pili i ka kūpono waiwai. Penei, a me ka mea ulu ikaika, oolea, paakiki a me ka Nine Inch e kū'ē'ē mai. Akā, i ka mea ia manawa emi i ka welelau o ke kikoo a me ka permeability i kinoea, a ma ka ohu. It E e kaulana kolo ana i ia lŘlŘ ma hooloihi ae i haawe ana. Oia polyethylene mea biologically inert, a me ka mea hiki ke hoopuni ua hoʻopōaiapuni. I ka loa pono i loko o ka o kēia au nei. Olelo ana e pili ana i ka hoʻohana 'ana o ka polyethylene, ka mea e e kaulana i ka mea, ua hoʻohana' ia no ka hana o ka'ōpala a me nā ipu. No laila, e pili ana i ke kolu o ka? Iecaianoaaiiuo hele mai e hana i kekahi ipu lāʻau mōlina, a ua hoʻohana 'ia i loko o ka meaʻai hana, nā mea hoʻonani, kaʻa, consumer, ikehu mahinaai a me films. Akā, ka mea hiki ke loaʻa ka wā e pili ana Tube a me ka hōkiokio wahi. An nui ia Morohiha o keia mea o kona mea paʻa, haahaa ka lilo a me ka nanea ana o ka kuʻihao.

Low nuʻa polyethylene

Kēia laholio kukui crystallizable mea me ka wela ia'ku (ʻaʻohe haawe) ma ka laulā, mai -120 i +90 kekelē Kelekia. Ka waiwai i kekahi ikaika e kaukaʻi ma o ka pa apŘ o ke kūpono mea. Pela ka mea, he hua o ka ikaika, paakiki, oolea a me ka Nine Inch e kū'ē'ē mai. Together me keia polyethylene mānoanoa he kūlana e loli ai ka hopena ikaika, elongation, crack ia'ku a me ka permeability i kinoea, a ma ka ohu. Eia hou kekahi, ia mea i okoa dimensional kumupaʻa, a me ka nui loa hopena maikaʻi 'ole i kŘpa a haʻahaʻa wahie. It E e kaulana nō kiʻekiʻe Nine Inch ia'ku a me ka maikaʻi dielectric ano. Mai ka hopena maikaʻi - ma ka polyethylene e inoino bipi kūpaluʻia, a me nā mea kāhinu, ultraviolet pāhawewe. Biologically inert, hiki ke eaaei ua hoʻopōaiapuni. Pū nō e wehewehe aku i hoʻopale ai i ka pāhawewe. Noi o ka kiʻekiʻe-pa apŘ polyethylene hiki ke ike loa, i ka wa e pili ana oaoieei-, ka ai a me ka mahiʻai films. Oiai, o ka papa, ia mea,ʻaʻole ka mea wale koho.

laina polyethylene

He he laholio mea crystallizes. Ua hiki ke hoole aku i ke ana wela i ka 118 kekelē Kelekia. ʻO kekahi mea nui ia Morohiha o keia mea o kona ia'ku i kaʻuʻina, wela ia'ku a me ka hopena ikaika. Ua Ua hoʻohana 'ia no ka manufacturing pūʻolo helu, ipu a me nā ipu. He aha e kaumaha ana i ka PE? Ke ano o keia mea ka loa kiʻekiʻe hoʻohālike ai i ke koho mua nō i hoomakaukau ai ma ka ano o ka haʻahaʻa puʻe. Nolaila, oia i ka waiwai nani maikai. Akā nō, e like me ka rula, ka mea hiki ole ke equated me ke kiʻekiʻe-puʻe polyethylene.

E like me ka mea hiki ke hoʻokū 'ia e ka mea?

No laila, he paena uhi mākou i ke kumu o ke ano o ka polyethylene. Ma ka palapala ia hana? The loa Popular - he polyethylene kuina a me ka ho film. Kēia mau 'ano apau loa i ke ua hanaʻia mai kekahi mea nuʻa. Oiai nō ma laila i kekahi mau koho. Ke'ōlelo mai, no ka mea, o ka? Iecaianoaaiiie'ōlewa a me ka lahilahi Film o ka mea hoʻomano hoʻohana haahaa puʻe hoʻokokoke. Ka laula o ka loaa ana i nā puke, nō kāu hiki 1400 mm o, lōʻihi - 300 mau mika. Laina haahaa nuʻa polyethylene a oiʻoʻoleʻa, nae, ka mea e hoʻohana no ka hale i pono ole e loli ma: ka ia a lahilahi, hana, a ua'omoʻomoʻia 'atikala a no laila, ma luna o.

ka hopena

A eia ka mea hope,ʻaʻole e hōʻike i nā palapala hoʻokonukonu, e like me a, a hua mai la i polyethylene. GOST 16338-85 kuleana no ka? Iecaianoaaiiuo i ua hana i haahaa puʻe. Ua hana hou i ka makahiki 1985. GOST 16337-77 noho aupuni aku ai i nā nīnūnē e pili ana i ke kiʻekiʻe-puʻe polyethylene. He mea i oi kahiko, a me nā lā hoʻi i ka makahiki 1977 makahiki. Mau palapala normative māmala'ōlelo i loko o ka 'ike e pili ana i nā koi no ka mea, mai a i ua hanaʻia a me ka ho film,'ōpala, a' ē aʻe likeʻole huahana. Eia hoʻi, he mea pono e hoʻomaopopo i ka laulā huahelu o ka noi o nā huahana loaa a me kona? Ueo 'ano. Ke'ōlelo mai, no ka laʻana, loa, he pono ole ka ikaika polyethylene ho film. Lākou peculiarity mea ia no ka mea hookahi no kona mānoanoa i ke poo a me ka poohiwi ma luna o ko lakou mau waiwai ma mua o kaʻike mau huahana Eia kekahi laʻana. No ka mea oia ka ikaika polyethylene Film e tablecloths, i mau aa moni, a he nui nā maikaʻi kēia mea. Lākou ka waiwai i loaa mai ma o ka hoike ana o kūikawā nā huakaʻi mai maoli paha kemikala olona.
