Kodi chitsanzo cha ma cellulose?

Cellulose edioni amayimira gulu losiyanasiyana lazinthu zochokera ku cellulose, polysacchairide wopezeka m'makoma a cell a mbewu. Izi zimagwiritsidwa ntchito kwambiri pamafakitale osiyanasiyana chifukwa cha zinthu zapadera, kuphatikizapo kukula, kukhazikika, kukhazikika, mafilimu, ndi maluso osungira madzi. Tikamafufuza kwakukulu, tidzayang'anitsitsa dziko la cellulose etralose, kupenda kapangidwe kawo, njira, njira, zogwiritsira ntchito magawo osiyanasiyana.

1. Kuyambitsa kwa cellulose etrase:

Cellulose eds ndi ma cellulose omwe ena a hydroxyl (--oh) magulu a polymer polymer amasinthidwa ndi magulu ether. Zosintha izi zimasintha kapangidwe ka kasinthidwe ka cellulose, ndikusungunuka m'madzi ndi ena mabele, zomwe sizili choncho ndi cellulose. Magulu a ma hydroxyl omwe ali ndi kulumikizana kwa eyathe kumapereka cellulose etralose etrature katundu, kuphatikizapo kusungunuka, kuphatikizapo kuchepa kwa mafilimu, komanso kukhazikika kwa mafilimu.

2. Kapangidwe ndi katundu wa cellulose et:

Mapangidwe a cellosese yosiyanasiyana amatengera mtundu ndi kuchuluka kwa zolowa m'malo. Cellulose wamba etralose cellulose, ethyl cellulose, hydroxthyl cellulose, hydroxypropyl cellulose, ndi carboxymethy cellulose. Izi zimawonetsera katundu, monga kusungunuka, mamasukidwe, mawonekedwe a gel, komanso kukhazikika kwamatenthedwe, ndikuwapangitsa kukhala oyenera mapulogalamu osiyanasiyana.

Mwachitsanzo, methyl cellulose imasungunuka m'madzi ozizira koma amapanga gel osakaniza, ndikupanga kukhala koyenera kugwiritsa ntchito zinthu zofunika kwambiri, monga mankhwala opangira mankhwala. Komabe, cellulose, imatha thupi m'madzi koma osungunuka okhazikika, akupanga kukhala yoyenera kugwiritsa ntchito zokutira, zomata, komanso makina operekera mankhwala osokoneza bongo.

3. Kaphatikizidwe ka cellulose et:

Cellulose eds nthawi zambiri amapangidwa mosiyanasiyana kudzera mu mankhwala a cellulose pogwiritsa ntchito mitundu yosiyanasiyana. Njira wamba zimaphatikizapo kukwaniritsidwa, kutulutsa, ndi makutidwe ndi okosijeni. Kudzikuza kumafuna kuchitira cellulose ndi alkyl hardes kapena alkylene oxides pansi pa alkalines kuti ayambitse ulalo wa ether. Chifukwa chake, limaphatikizapo kuchita ma cellulose ndi carboxyylic acids kapena acid acid kuti apange zigawo za esster.

Kaphatikizo wa cellulose edzose kumafunikira kuwongolera mosamala kuti akwaniritse digiri yofunikira ndi katundu. Zinthu monga momwe zimakhalira nthawi, kutentha, Ph, ndi othandizira kusewera moyenera posankha kupambana kwa kapangidwe ka kaphatikizidwe ka kaphatikizidwe.

4. Mapulogalamu a cellose et:

Cellulose ers amagwiritsa ntchito ntchito zochulukirapo pamakampani osiyanasiyana chifukwa cha zomwe zimachitika. Pakugulitsa zakudya, amagwiritsidwa ntchito ngati otsatsa, okhazikika, ndi odzoza, ndi mavaturus muzopanga, sopo, zovala. Mwachitsanzo, celyl imagwiritsidwa ntchito ngati thickiner ndi bander mu zinthu zophika mkate, ayisikilimu, ndi ma analogi nyama.

M'makampani ogulitsa mankhwala, cellosesese yogwiritsidwa ntchito ngati ma bingars, osagwirizana, komanso omasulidwa - omasulidwa - omasulidwa nawo pamapangidwe a piritsi. Hydroxypropyl Medielose (HPMC), imagwiritsidwa ntchito kwambiri ngati khola mu piritsi la piritsi chifukwa cha zomwe zimapangidwira komanso zophatikizira zina.

Mu makampani omanga, cellulose yopangidwa imagwiritsidwa ntchito ngati zowonjezera mu simenti ndi matope osokoneza bongo, kusungidwa kwamadzi, ndi malo otsatsa. Mwachitsanzo, ma hydroxyethyl cellulose (hec), nthawi zambiri amagwiritsidwa ntchito ngati thunthu losungidwa ndi madzi m'masamba a mataile, ma grout, ndi ma CRARE-zochokera.

Mu chisamaliro chamwini komanso makampani odzikongoletsa, cellulose opangidwa ndi zinthu zosiyanasiyana, kuphatikiza shampoos, zowongolera, zonona, ndi zotupa. Hydroxypropyl cellulose (mwachitsanzo, amagwiritsidwa ntchito ngati wothandizika ndi wopanga makanema muzogulitsa tsitsi, pomwe carboxymethyl celluse (cmlsifair mu mawonekedwe a khungu.

5.. Malingaliro amtsogolo ndi Zovuta:

Ngakhale anali ofunikira kwambiri kugwiritsa ntchito mafakitale osiyanasiyana, cellulose yosiyanasiyana, kuphatikiza mavuto azachilengedwe, zoletsa zowongolera, komanso mpikisano kuchokera ku zinthu zina zosankha zina. Kugwiritsa ntchito cellulose edd kuchokera ku magwero osinthika ndi kukula kwa njira zokhazikika ndi masikesi omwe amagwiritsidwa ntchito ndi malo ofufuza ndi chitukuko.

Kuphatikiza apo, kupita patsogolo ku Nanotechnology ndi biotechnology akutsegulira mwayi watsopano wosinthira cellulose etralose et, zomwe zimapangitsa kuti zinthu zachilengedwe zikhale ndi zinthu zowonjezera.

Pomaliza, cellosese yozungulira imayimira gulu losiyanasiyana lazinthu zosiyanasiyana mafakitale osiyanasiyana. Malo awo apadera, kuphatikizapo kusungunuka, kuyika mafakisoni, ndi luso lopanga mafilimu, zimapangitsa kuti akhale ofunikira mu chakudya, mankhwala opangidwa, zomanga, komanso zomwe amasamalira. Ngakhale akukumana ndi mavuto, monga zoletsa zachilengedwe komanso zoletsa zowongolera, cellulose etras, cellulose etters, cellulose etters, ma cellulose edde akupitilizabe kugwiritsira ntchito gawo ndi magwiridwe antchito a ogula ndi mafakitale.
