Kemikala polymers

I keia la, me ka hoʻohana 'ana o kekahiʻano o polymers, paha, ole e hoi i noonoo ai i kekahi i kekahi o kēia? Iecaianoaaiiuo. Ka mea, lanakila 'o ia i kekahi Hoʻohaku nā hana i ka mea kaumaha ka hana a me ka? Ieoaeunoai e like me ia ma ka malamalama a me ka ai na hana. He aha ka keia mana kupaianaha mea?

He aha nā polymers

Kēpau - mea he macromolecular waiwai iloko olaila o recurring kaula kanu'ōiwi (monomers). hiki e loa nui na huahelu ma ka pīlali kaulahao. Lākou AaOIeIOUIeXAOAaIN a me kekahi i kekahi, ma ka mea o ka covalent paa ana i ka paipai i ke kahua o ka macromolecules.

Polymers i ke aloha a me'okanikaʻole kumu. ʻO ke aloha hakakino i huiʻia, i ke alo o ke kalapona ua koi, i mea ole apau i ka'okanikaʻole a kemikala hale. Ke aloha polymeric hui i hehee ai-kalapona-kaula a me ka hetero.

Eia kekahi, o ka polymers nō māheleʻia i loko o kona ano maoli,ʻimi hoʻopunipuni a me ka kemikala. Ma ke aha ka ke aloha monotsepey ma kekahi Nine Inch reactions makaukau likeʻimi hoʻopunipuni macromolecular hui. No ka laʻana, pulupulu hulu ole ma ke kaʻina hana Nine Inch, ua hoohuliia mai i loko o kemikala polymeric olona.

A me ka helehelena o kaʻimi hoʻopunipuni polymers o kemikala? Hoikehonua, manufacturing keʻano o ka hanaʻana ae i ka mea i hanaia o kaʻimi hoʻopunipuni paha synthesizing polymers me ka hoʻohana 'ana o ke aloha mea,ʻo ia hoʻi, ke kahua o kaʻimi hoʻopunipuni mea. i hoomakaukau kemikala polymers ma ka mea hoʻololi kemikala o haʻahaʻa-hakakino waiwai 'ole mai' ē aʻe kemikala polymeric mea.

Mea Maluna o polymers

Conditional systematization classifies ia i loko o ka pūʻulu penei:

1. Natural holoholona polymers hoʻohanaʻia ke kanaka no ka lōʻihi manawa. Ano he kumu hoʻohālike nō ke kēia: gelatin, glycogen.

2. Natural kanu polymers, a mākou nō i kama'āina. Kēia pia, laholio, kelulose a me ka lignin.

3. Natural mea pōhaku polymers - ua hoʻomano hoʻohana 'ia ka silica i ole pōaka mea pōhaku i kapa pōhaku aniani. Pena aniani i ka pohaku maikai - ametuseto. Ma me ka pauka, ano ka mea, ua hoohuliia mai i loko o ka mau one.

4.ʻimi hoʻopunipuni polymers i mai ke aloha monomers. Kelulose waiwai leaching hoʻohana polyesters i: ethylcellulose, benziltsellyuloza a me ka methylcellulose hoʻohana ma o ka HW oihana puolo. He nui na waiwai i i ka hulu hipa,ʻili, für, silika, a laila, ma luna o. D.

5. kemikala polymers e hoʻomano hoʻohana ma na hanalima nāʻoihana, loaa mai mākou i ka nui hohola. No ka laʻana, ma ka malamalama, ka hana i ulana, a knitted fabrics o kemikala olona, e like me polyester, nylon, polypropylene, nitrone. Ka mea, ua nui loa ikaika a me kaʻaneʻane indelible. Kemikala polymersʻikepili ia ho i ka walaʻauʻana me nā hale o ka'aʻaʻa olona, i loaa mai ma ka polycondensation o kekahi Nine Inch waiwai nāʻakika e like me'etolina diamine, hexamethylene diamine, he polyolefin a polyacrylonitrile. No laila, i ke kumu o ano polimerov- "poʻe mākua" pū i hiki, a me ka loa hou polisoedineniyam. E like me ka hopena, ua loaa i ka loa i ka malamalama a me ka laholio mea me ka haʻahaʻa thermal conductivity, e hoʻopale i ka Nine Inch, physical a me ka lewa loa.

Mahalo i ka nui waiwai waiwai, ua loaʻa kemikala polymers noi ole wale i loko o ka lole hana, akā, i ka oihana lapaau, nā mea hoʻonani a me ka mea ala hana, mahiʻai, kaʻa, e kukulu, ka hale a me nā mahinaʻai.
