Inkqubo yemveliso kunye nokusebenza kwe-hydroxyythl seluplose (hec)

Intshayelelo

I-HydroxyEtheetheetheetheetheethy (Hec) i-polymer ye-Ionic enyibiliki isetyenziswa ngokubanzi kwi-oyile ekhuphayo, ingubo, ukwakhiwa, imichiza yemihla ngemihla kunye namanye amasimi. I-HEC ifunyenwe ngokuguqulwa kwemichiza yeselfowuni, kwaye iipropathi zalo kunye nokusetyenziswa kwayo zimiselwa ikakhulu zii-hydroxyls ezindlwini ze-hydroxythy kwimolekyuli.

II. Inkqubo yemveliso

Inkqubo yemveliso ye-hec ikakhulu ibandakanya la manyathelo alandelayo: Isimo se-selsulose, ukuhlamba, ukupheliswa komzimba, ukomisa kunye nokucima. Oku kulandelayo yintshayelelo eneenkcukacha kwinyathelo ngalinye:

I-etherise

I-seluplose iqala ukuphathwa ngeAlkali ukuya kwi-Alkali SellUlose (Selelise Alkali). Le nkqubo idla ngokuqhutywa kwi-reactor, isebenzisa isisombululo seSodium hydroxide ukunyanga isellulose yendalo ukuze ifomu i-alkali sellulose. Impendulo yekhemikhali yile ilandelayo:

Iseli-oh + naoh `→ Iseli-o + h2ocell-oh + naoh` → Iseli-o + h 2o

Emva koko, ialkali secelose i-projeks kunye ne-e-itholene oxide ukuba yenze i-hydroxyythyl sellyulose. Impendulo iqhutywa phantsi koxinzelelo oluphezulu, ngesiqhelo i-30-100 ° C, kwaye impendulo ethile yile ilandelayo:

Iseli-o-na + ch2c2c2O → iselfowuni

Le mpendulo ifuna ukulawulwa kweqondo lobushushu elichanekileyo, uxinzelelo kunye nenani le-ithoylene oxide ukuba iqinisekise ukufana nomgangatho wemveliso.

Ukuhlamba

Isiphumo sehedeni esemphuli esihlala sino-Alkali ongenamsebenzi, i-e-ithylene oxide kunye nezinye iimveliso ze-ofisi, ezifuna ukususwa ziindawo zokuhlanjwa kwamanzi okanye zokuhlanjwa kwendalo. Isixa esikhulu samanzi siyadingeka ngexesha lenkqubo yokuhlamba amanzi, kwaye amanzi amdaka emva kokuhlamba kufuneka aphathwe kwaye akhutshwe.

Ukuphelelwa ngamanzi emzimbeni

I-hec emanzi emva kokuhlamba kufuneka ikhutshwe ngumzimba, idla ngokufihla ngokufihlakeleyo okanye ukwahlulwa kwe-centrifugal ukunciphisa umxholo wokufuma.

Ukomisa

I-HEC yeHelding Decdddddy yomile, ihlala ngokutyibilika okanye ifleshi. Iqondo lobushushu kunye nexesha kufuneka lilawulwe ngokungqongqo ngexesha lenkqubo yokomisa ukuthintela ukonakala kobushushu obuphezulu okanye ukuphazamiseka.

Ukugaya

Ibhloko ye-hec eyomileyo kufuneka ibe yomhlaba kwaye icekeceke ukuze ifumane ubungakanani be-iyunifomu, kwaye ekugqibeleni yenza umgubo okanye imveliso yegranular.

III. Iimpawu zentsebenzo

Ukungathobeli kwamanzi

I-HEC inomhlaba olungileyo kwaye unokunyibilikisa ngokukhawuleza kuwo omabini amabanda kwaye ashushu ukwenza isisombululo esibonakalayo okanye sokuzalelwa. Eli mpahla yomhlaba lenza isetyenziswe ngokubanzi njenge-thi checkener kunye nokuzinzisa kwimveliso kunye neemveliso zemichiza zemichiza.

Ukuthambisa

I-HEC ibonisa ifuthe elinamandla kwisisombululo esinamandla, kwaye ukubonwa kwalo kunyuka ngokunyuka kobunzima bemolekyuli. Le mpahla yokuthambisa yenza ukuba ikwazi ukudlala indima ekuthambekeni, ukugcinwa kwamanzi kunye nokuphucula ukusebenza kokwakha kumakhonkco asekwe emanzini nasekuphumezeni ukufa.

I-rheology

Isisombululo se-Hec AICTERITER ineepropathi ezizodwa ze-hec zezahlukileyo ze-ratheologries, kunye notshintsho lwalo lokutshintsha kunye notshintsho lwenqanaba le-Shear, ibonisa ukucofa isherading okanye i-pseudoplastity. Eli mpahla ye-sulological iyenza ukuba ihlengahlengise ukulungelelanisa nokusebenza kwentsebenzo kunye nokwakha ukuntywila kunye nokuntywila kweoyile.

Ukukhutshwa kunye nokunqunyanyiswa

I-HEC inezilolo ezihle kunye nokumiswa kwepropathi, ezinokuzinzisa amasuntswana okanye amathontsi kwinkqubo yokusasazwa ukuthintela ukuqinisekiswa kunye nokuhlala. Ke ngoko, i-hec ihlala isetyenziswa kwiimveliso ezinje ngemali yokunxiba kunye nokumiswa kweziyobisi.

Biodegradiance

I-Hec yindawo yendalo ekhupha i-bileoese yendalo, akukho lungcoliseko kwindalo, kwaye ihlangabezana neemfuno zoKhuseleko lweNdalo oluGrike.

Iv. Amasimiselo

I-Coasthings

Kwingubo esekwe emanzini, i-HEC isetyenziswa njenge-thi choner kunye nokuzinzisa ukuphucula ulwelo, ukusebenza kwentsebenzo kunye neempawu ezichasene nemveliso.

Ukwakhiwa

Kwizinto zokwakha, i-HEC isetyenziswa kudaka olusekwe kwisamente kunye nomgubo ongezantsi wokuphucula ukusebenza nokwakha amanzi.

Iichemicals zemihla ngemihla

Ukucofu, i-shampoos, kunye namazinyo, i-HEC isetyenziswa njenge-thi checker kunye nokuzinza kokuphucula iziva kunye nokuzinza kwemveliso. 

Ii-olifields

Kwi-oyilefield offills kunye ne-flacings, i-HEC isetyenziselwa ukuhlengahlengisa i-RUOOOOOLOGY NOREDITSTERE YEZOBUCHULE BOKUGQIBELA

Ipeyinti

Kwinkqubo yepapermunge, i-HEC isetyenziselwa ukulawula i-fallp fluity kwaye iphucule iyunifomu yephepha kunye nendawo yephepha.

I-HydroxyEtheetheetheetheetheetheetheethy (Hec) isetyenziswe ngokubanzi kwimimandla emininzi yeshishini ngenxa yomoya obalaseleyo wamanzi, ukuthambisa, iipropathi ze-rickeloging, i-ratheologing, i-eultaibles, i-EULTATIONS, kunye nokumiswa kwe biodegraphiady. Inkqubo yayo yemveliso ivuthiwe. Ngamanyathelo okuthumeza se-seluplose, ukuhlamba, ukupheliswa komzimba, ukomisa kunye nokugaya, iimveliso ze-hec ezinentsebenzo efanelekileyo kunye nomgangatho olungileyo unokulungiswa. Kwixa elizayo, ngokuphuculwa kweemfuno zoKhuselo lweNdalo kunye nokuPhuhliswa kweTekhnoloji, amathuba esicelo se-Hec aya kusinda.
