Polymers gaosi

I aso nei, e aunoa ma le faaaogaina o le tele o polymers, atonu e le mafai ona vaai faalemafaufau i soo se tasi o le gaosiga o ona po nei. Latou manumalo i se tulaga iloga o kamupani i totonu o alamanuia mamafa ma le fausiaina faapea foi i le alamanuia malamalama ma meaai. O le a lenei mea faavavega?

O a polymers

Resin - o se mea macromolecular aofia ai faisoo o fausaga filifili (monomers). O iunite i le filifili polymer mafai ona matua tele. Latou fegalegaleaiga ma le tasi i le isi e ala i noataga covalent lea siitia le faavaeina o le macromolecules.

e Polymers amataga faatulagaina po o inorganic. O le tuufaatasi molecular faatulagaina, e manaomia le afioaga o le carbon, lea e le o taua i le fausaga inorganic po gaosi. tuufaatasi polymeric faatulagaina o elemene-carbon-filifili ma hetero.

Gata i lea, o le polymers vaevaeina pea i le lalolagi, faafoliga ma gaosi. Lea le monotsepey faatulagaina e tali nisi vailaau ua saunia pei o lotoa macromolecular faafoliga. Mo se faataitaiga, vavae fulufulu mamoe po o se faagasologa o le vailaau, ua liua i alava polymeric gaosi.

Ma o le a foliga o polymers faafoliga o gaosi? Po nei faiga gaosiga faatagaina le foafoaga o se polymers palasitika pe synthesizing e aunoa ma le faaaogaina o mataupu faatulagaina, o lona uiga, i le faavaega o mea faafoliga. ua saunia polymers gaosi e tuufaatasia faigofie o le maualalo molecular vailaau po o mai i isi mea polymeric gaosi.

faavasegaina o polymers

systematization tuutuuga classifies i latou i le vaega nei:

1. Faalenatura polymers manu faaaogaina e le tagata mo se taimi umi. Faataitaiga o nei: gelatin, glycogen.

2. polymers laau Faalenatura, lea ua tatou masani foi. O lenei māsoā, paʻu, cellulose ma lignin.

3. Faalenatura polymers minerale - Ua lautele faaaogaina silica po quartz minerale taʻua tioata papa. tioata vali avea o se maa taua - amethyst. I pauta pepa faatumu ua liua i le oneone masani ai.

4. polymers faato faia mai monomers faatulagaina. mea leaching faaaogaina polyesters Cellulose faia: ethylcellulose, benziltsellyuloza ma methylcellulose faaaogaina i le alamanuia vali. O le tele o mea ua faia i fulufulu, paʻu, fulufulu, silika ma isi. D.

5. polymers gaosi ua lautele faaaogaina i le tele o vaega tau alamanuia, tatou te maua a salalau tele. Mo se faataitaiga, i le ua lalagaina malamalama alamanuia ma koloseina le ie o alava gaosi e pei o polyester, nylon, polypropylene, nitrone. I latou o ni matua malolosi ma toetoe lava e le mafaagaloina. faamatalaga polymers gaosi fai ma sui o le faavae autu o alava pepa solo maua e polycondensation o nisi mea vailaau acids e pei o diamine ethylene, diamine hexamethylene, o se polyolefin po polyacrylonitrile. O le mea lea, o le uiga faavae polimerov- "tuaa" ua faaoo atu, ma se polisoedineniyam fou atoa. O se taunuuga, tatou te maua a tele mea malamalama ma le ofuvae ma conductivity vevela maualalo, e tetee atu i vailaau, aafiaga faaletino ma le ea.

Faafetai i le tele o meatotino taua, maua polymers gaosi talosaga e le gata i le alamanuia lavalava, ae faapea foi i vailaau faafomai, cosmetics ma fagusausau alamanuia, tau faatoaga, tautaavale, fausaga, aiga ma isi fanua.
