Waerau waihanga

I teie mahana, i waho te whakamahi o te momo o waerau, pea, taea ki te whakaaro tetahi tetahi o production hou. riro ratou i te tūranga tino i roto i te ahumahi taimaha, me te hanga e rite ana te pai rite i roto i te ahumahi marama, me te kai. He aha te mea tenei rauemi semeio?

He aha e waerau

Kapia - Ko te taonga macromolecular arā, o auau hanganga mekameka (waetahi). Taua wae i roto i te mekameka polymer e taea e tino nui. Ratou pāhekoheko ki ia atu i te tikanga o here kotuari e whakatairanga te hanganga o nga macromolecules.

Waerau he takenga organic inorganic ranei. Ko te pūhui rāpoi organic, kua hiahiatia te aroaro o te waro, e kore te mea nei faufaa ki te hanganga pararopi waihanga ranei. Organic pūhui polymeric he huānga-waro-mekameka me te hetero.

I tua atu, wehea tonu nga waerau ki tūturu, tāwhaiwhai me te waihanga. Ai te monotsepey organic i etahi tauhohenga matū rite rite pūhui macromolecular horihori. Hei tauira, miro huruhuru i te tukanga matū ranei, kua tahuri ki muka polymeric waihanga.

A he aha ngā āhuatanga o waerau tāwhaiwhai o waihanga? Modern tukanga whakanao tukua te hanganga o te waerau horihori synthesizing ranei kahore te whakamahi o te mea waro, e ko, te hanganga o ngā rauemi horihori. Kua rite waerau waihanga i ariā ohie o matū iti-rāpoi ranei i te tahi atu mau materia polymeric waihanga.

whakarōpū o waerau

whakarōpū ratou systematization Herenga ki te rōpū e whai ake nei:

1. waerau kararehe Natural whakamahia e te taata nei mo te wa roa. Tauira ko te whai ake: gelatin, glycogen.

2. waerau tipu Natural, e he mōhio hoki matou. Tenei māngaro, rapa, cellulose me te lignin.

3. waerau kohuke Natural - Kei te whakamahia whānuitia takawai kiripaka ranei kohuke i huaina toka karaihe. riro karaihe pania te kohatu utu nui - ametihita. I roto i te paura puka e tahuri ai i roto i te onepu mua.

4. waerau Artificial hanga i waetahi organic. matū cellulose wīra te whakamahi i ngā pūhui i hanga: ethylcellulose, benziltsellyuloza me te methylcellulose whakamahia i roto i te ahumahi peita. E hanga tokomaha matū pērā o huruhuru, hiako, huruhuru, te hiraka, me te pera i runga i. D.

Kei te whānui 5. waerau waihanga whakamahia i roto i te maha rāngai ahumahi, riro matou he horapa nui. Hei tauira, i roto i te ahumahi marama e whatu, ka whenu papanga o muka waihanga pērā i pareaku, nairona, polypropylene, nitrone. he nui te kaha, me te tata e ngaropoina ana ratou. waerau waihanga raraunga e tohu ana i te hanganga taketake o muka kikokiko whiwhi e polycondensation o etahi matū matū waikawa pērā i ethylene tiamine, hexamethylene tiamine, he polyolefin polyacrylonitrile ranei. Na reira, kei te tuku te mau huru taketake polimerov- "matua", me he polisoedineniyam katoa hou. Ka rite ki te hua, whiwhi tatou i te rauemi tino marama, me te rapa ki iti kawe waiariki, he ātete ki ngā pānga matū, tinana, me te kōhauhau.

Ngā mihi ki te maha ngā āhuatanga tino, kua kitea waerau waihanga tono e kore anake i roto i te ahumahi pueru, engari ano hoki i roto i te rongoa, poke me te ahumahi kakara, ahuwhenua, automotive, hanga, whare, me te tahi atu mara.
