Haʻilula polypropylene. Ka waiwai a me ka noi o ka polypropylene

A me polymers i mai kēia mau mea, ka hale 'ikamu a me accessories - keia mea nui i kekahi hapa o ka hana, a kanaka ola i loko o mau. Kumu waiwai, Eia naʻe, loa depleted i kā lākou hana. Nolaila, kanaka i ke aʻo i synthesizeʻimi hoʻopunipuni nā mea i ka helu o ka mea nui oaoieei-ano. Kekahi o kēia mau mea polypropylene. Nine haʻilula o keia hui, o ka oi aku kona waiwai a me ka 'ole o ka lātoma e e noʻonoʻo i loko o ka pauku.

Polymers - he mau ano o

Kēia papa o ka i huiʻia nā poʻe mea i ke kiʻekiʻe loa waiwai o ka hakakino kaumaha. No ka mea, polymers - i luna 'ke aloha i huiʻia e komo ana i mau hana hou' ia lātoma huahelu, a hiki e mai kekahi mau umi a hiki i na haneri, na tausani a miliona.

ʻO kēia mau pūʻulu hiki e hookoaia i waena o nā mea a pau polymers:

1. Natural me Kinohi - nā polokina, nukeleaʻakika nā lātoma o ATP, a no laila, ma luna o.
2. ʻimi hoʻopunipuni - ka poe e i ka nānā 'ana ma luna o kona ano maoli, akā, ua ua chemically Hoʻololi' i mea e hoʻoikaika 'ana i lawelawe. No ka laʻana,ʻimi hoʻopunipuni rubbers.
3. Kemikala - ka poe mea i hana wale ma Nine Inch reactions, hoʻololi kemikala i loko o ke keʻena hoʻokolohua, a? Iecaianoaaiiie mea kanu. Eia examples i kemikala fabrics a me ka olona,, polyethylene, kemikala rubbers, Tewetewe koloriside, polypropylene a me na mea e ae.

All mahinaʻai hoailono aku la me ka pae o ka polymers - he nui hanalima maka mea no ka makaukau a me ka? Iecaianoaaiiie o kekahi mau ipu, hale 'ikamu, mea aniani, toys, lako a me na mea e ae.

Me ka Poeikohoia o ka mea nui kemikala polymers

Ke Nine Inch haʻilula o kekahi o ka loa nui 'elele o kemikala polymers ua palapala like (-CH ₂ -CH ₂ -) _n. Kēia polyethylene. Kona mau mea o ka pono i ikeia. Kēia hale e pono ai (ikona ho film), a me ka hanalima, a me ka ai hana (hāʻawe mea). Eia naʻe,ʻaʻole ka mea, o ka loa, he pono ole, akā, i ka mea wale Luna mea nui no ka kānaka. Ua hiki no hoi loaʻa na polymers like:

• PVC;
• polypropylene;
• polyisobutylene;
• polystyrene;
• Teflon;
• Tewetewe'ākeka, a me na mea e ae.

Ua mea i loko o ka hana pāʻoihana, a no ka hana ana i cookware Radio he nui a Mānoa i nā puke e like me polypropylene. No laila, ka mea, ua hou noonoo kona hiʻona mai ka Nine Inch wahi o ka Hawaii.

polypropylene haʻilula

Mai ka oiai o ka 'epekema kemika, ka haku mele' ana o ka waiwai hiki ke hoikeia ma kekahiʻano o nā papakuhikuhi. Ke koho mua o ka hakakino ano o ke kakau ana. Ma keia hihia i ka haʻilula mea like polypropylene (C ₃ H _{6) n.} Hope polimerazatsii N Ua degere, a laila i ka helu ana o mall huahelu ma ka loiloi mua macrochain.

Keia mooolelo paipai i ka qualitative a laupaʻi haku mele 'ana o ka lātoma. Polypropene ninoieo o kalapona a me ka hydrogen nā'ātoma, a me kā lākou helu i loko o ka lātoma mokuna mea niioaaonoaaiii like me 3/6, a me ka huina kaulahao hilinaʻi nui ma luna o ka 'inideka n. Inā mākou e kamailio e pili ana i ka 'ole o ka hui, ma ke kauoha o nā'ātoma i loko o ka lātoma, lailaʻoe pono he okoaʻano o ka hoʻopaʻaʻia.

Polypropylene: mall haʻilula

Recordʻano, a hōʻike i ka mea o'ātoma paa ana i loko o ka lātoma, i kapaʻia ka mall haʻilula. No ka 'ona noonooʻaneʻi ka mea, e loaʻa i ka palapala. (Ch ₂ -CH-Ch ₃ -) _n. ʻae nō hoʻi, ka valence nā'ātoma, he pono ole i ke aloha kemika, a ua paa ia ma keia hihia. Haʻilula polypropylene a polypropene hōʻike i ke ano o ka lātoma pa alima underlies hui. Ua ua i hana mai he unsaturated hydrocarbon (alkene) propene paha propene. Kona empirical haʻilula: C ₃ H _8.

Ka loiloi mua lātoma

Ke haʻilula no ka loaa ana i ka polypropylene lātoma like penei: (-CH ₂ -CH-Ch ₃ -). Inā keia apana nahaha ua hai haneri o ka manawa, ua loaa ka mea a pau macromolecule, he kemikala pīlali, i ua noʻonoʻoʻia. Eia hou, ua kuhikuhi mua mākou mai i nā mea a pau i ka ho mea no ka polymerization naoh E e noonoo maʻamau alkene - propene. He mea polypropylene lātoma. Mall haʻilula e e palapala me Ch ₃ -CH = Ch _2. At wanaao ae makemake papalua hoopaa moiety i hanaʻia i ka polymerization. I hookahi lātoma pa alima, a hou 'ano apau loa i ka pīlali macromolecule.

Helu a me ka Nine Inch waiwai

Polypropylene haʻilula (-CH ₂ -CH-Ch ₃ -) _N haawi i PAaIEN o kona kino a me ka Nine Inch ano. E helu i ka nui poʻe.

1. Helu waiwai o ka pīlali: 0,91 g. / Knm ^3, paʻakikī, abrasion hoʻopale,ʻaʻole malalo i ka popopo. White, opaque. No ala. Ma ka wai, ke aloha nā'uheheʻe ma maʻamau mahana insoluble. I ka 'inideka luna 100 ⁰ C ua mea hoʻoheheʻe ma ka hydrocarbon i huiʻia. Ua hoʻomaka e hoopalupalu mai ma hope o 140 ⁰ C, i 170 ⁰ C heheʻe. Ua ka wela a me ke anu e kū'ē'ē mai.
2. Nine waiwai. Mai ka viewpoint o ka ha awina, polypropene hiki e wahi ana i ka kūpono kou inert mea. He hiki no reacting wale me ka oxidants pakahi aku la ia ikaika: Fuming nitricʻakika, chlorosulfonicʻakika, oleum,ʻeleu halogens (fluorine, chlorine). No ka wai 'Aʻole e launa pū' ana i nā mea a pau, a hiki i ke kiekie ana wela. No ka mea wale nō i oxygen reacts ma luna o irradiation me ultraviolet malamalama, ka mea, ua pu ma hoʻololi iho o ka pīlali. O ke aloha nā'uheheʻe me ka hoʻoulu ka mahana e pehu ae a me ka hoike mai.

Kekahi mau waiwai hiki ke wahi i ano o ka mea i ua hoʻohana 'ia ma ka hana. Eia naʻe,ʻaʻole a pau o ka mea hookahi polypropylene. Aia i kūikawā mea hoʻonui stabilizers, a i hana hoʻohana okoa papa o ka pīlali ma lalo o noonoo.

Material hoakaka

He hiki no i hoʻokohu 'ia kekahi mau kumu o ka waiwai i uluhia e polypropylene mea. Ano o kona penei:

1. I ka hahana maoli nō kēia mea hiki ke maule, hoopalupalu mai mamua.
2. Aia i conduction waiwai.
3. Udarostoek, mau nō Wear.
4. Hoʻopale i ka abrasion.
5. Kūnewa ka wā paku ole ia i ka lń a me ka oxygen, akā, i ke kaʻina o lawa ka lohi.
6. E like me ka pīlali i he uuku hakakino kaumaha.
7. Ua he keʻokeʻo, translucent,ʻaʻoheʻaiʻana a me ka honi.
8. Inā'ā aʻole e hoʻokuʻu akula nā palapala waiwai, e kī ana i kekahi kukui Floral ala.
9. He'ōlewa, mau nō, hoʻopale i nāʻano likeʻole o ka haumia ea.
10. Ua ka wela a me ka hau.

All mahinaʻai ia me polypropylene like me ka mea waiwai e ka mea e pono ai no keʻano o nā mea e pono ai. He oluolu ke hana, oluolu e malama a me ka hana i loko o ka hana ana i kekahi kaiaulu o ka hoʻokele waiwai.

I ka huina, ma laila nō ekolu papa kuhikuhiEʻano likeʻole o kēia mea:

• attaktichesky;
• syndiotactic;
• isotactic.

Ka papa likeʻole ma waena o ia - ia mea i ka māhele 'ole o ka lātoma. Manaʻoi - ka meto hui i loko o ke kaulahao. I hoakaka ole stabilizing mea hoʻonui, i ka helu o ka lātoma huahelu i loko o ka macrostructure.

Paka i ka mea kekahi i loko o ka palapala o ka granular mea pōaka 'ole paha i loko o ka palapala o ke olona, a lahilahi.

Mau mea o ka i

Material polypropylene hoʻohana no ka-i? Iecaianoaaiiuo likeʻole Film,'ōpala ipu, ai pahu waihona o. He no ka mea, ua ana i ka ea na kiaha a me nā 'ikamu o disposable tableware. Keia mea ua hoʻohana 'ia no ka hana mau nō, hoʻopale i Nine Inch Luna polypropylene palama na ohe.

Ua Ua hoʻohana 'ia no ka ho okumu ana i shumonepronitsaemyh mea. Lina leki - ia mea i kekahi o polypropyleneʻano likeʻole.

Attaktichesky mea ua hoʻohana 'ia e hana ai:

• mastics;
• adhesives;
• caulking;
• lina leki;
• ? uoeai a no laila, ma luna o.

A nui helu o ka polypropylene a lahilahi, olona, lau no ka hana ana o toys, kālana, ka hale 'ikamu a me ko ka hale ona waiwai.
