Umzekelo we-Ethem

I-Selersese EtherUmzekelo yi-Polymer Poment eyenziwe nge-sellsese ngesakhiwo se-ether. Iringi nganye ye-glucose kwi-selsulose i-macromoleule iqulethe amaqela amathathu e-hydroxyl, iqela le-hydroxyl kwi-atoni yesithandathu ye-atom, kunye neqela lesibini lekhabhoni. I-hydrogen kwiqela le-hydroxyl litshintshwa yiQela le-hydrocarbon ukuba ibe yi-sellyulose. Yimveliso yokufakwa endaweni ye-hydroxyl hydroger ye-hydrocarbon iqela kwi-sellulose polymer. I-seluplose yi-polyhydroxy polymer computer ukuba inganyibiliki okanye inyibilike. I-seluplose inokuchithwa emanzini, i-dilute i-alkali i-solkali kunye nesinyibilikisi se-organic emva konyamezelo, kwaye ineempawu ze-thermoplastic.

I-Telupelose Ether yikota eqhelekileyo yothotho lweemveliso eziveliswe yimpendulo ye-alkali selutase kunye nearhente yokukhuthaza phantsi kweemeko ezithile. I-Alkali SellUlose ithathelwa indawo ye-erhente eyahlukileyo yokufumana ii-selupose ezahlukeneyo.

Ngokweempawu ze-ionis zokuthathela izinto, iitywina zomzekelo zinokwahlulwa zangaphezulu ze-iodboxymethyl sellyulose) kunye ne-ionic (njenge-methyl ye-methyl Selelose) Iindidi ezimbini.

Ngokohlobo lokuthatha indawo yokuhlala,I-seluploseUmzekelo unokwahlulahlulwa ukuba i-Ether enye (njenge-methyl selsulose) kunye ne-ether exubeneyo (enje nge-hydroxypropyl methyl methyl methyl methyl methyl methyl methyl methyl methyl methyl metyl sellyulose). Ngokutsho komelele, unokwahlulwa kuba ngathi inyibilikithi yamanzi (enje nge-hydroxythyl seluplose) kunye ne-orgacce slicvelvent yomelele (njenge-orticpent). Ukufa kobuqhetseba okuxubeneyo usebenzisa i-selsulose enyibilikayo yamanzi, enokwahlulwa kudidi lokungavisisani okukhawulezileyo kunye nokulibaziseka ukuchithwa kokuchitheka emva konyango lomphezulu.

Imixokelelwane idlala indima ephambili ekuphuculeni iipropathi zodaka oluxubileyo kunye neakhawunti engaphezulu kwe-40% yexabiso lezinto eziphathekayo kudaka oluxubileyo. Inxalenye eqinisekisiweyo yentengiso yasekhaya ibonelelwa ngabavelisi bamanye amazwe, kwaye i-proresmere yemveliso ikwanikezelwa ngabathengisi. Ngenxa yoko, indleko zeemveliso zodaka ezixubileyo zihlala ziphakame, kwaye kunzima ukwehla udaka oluqhelekileyo kunye nodaka oluninzi kunye nendawo ebanzi. Iimveliso zokuphela kwemarike zilawulwa ziinkampani zangaphandle, abavelisi omanzi omileyo beenzuzo, ukufikeleleka kwexabiso eliphantsi; Ukusetyenziswa kwe-adming Acks Inkqubo yenkqubo nophando ekujoliswe kuyo, kulandele ukwenziwa kwamanye amazwe.

Iarhente yokugcinwa kwamanzi yeyona nto iphambili ekuphuculeni ukusebenza kwendawo yokugcina amanzi kodaka olomileyo kunye nolunye lohlobo oluphambili ukumisela iindleko zodaka oluxubileyo. Umsebenzi ophambili we-seluplose ether kukugcina amanzi.

Indlela yokusebenza ye-Selese ekrokrithini yile ilandelayo:

. Yenza umaleko wefilimu ye-hibric, inkqubo ye-slourry izinzile, kwaye ikwaphucula i-slirry kwinkqubo yokuxubanisa i-gesity kunye nokwakhiwa kwesiliphu kunokuhamba kakuhle.

(2)I-Selersese EtherIsisombululo ngenxa yesakhiwo sayo semolekyuli, ukuze amanzi akwenziwe udaka ukulahlekelwa, kwaye akhululwe ngokuthe ngcembe ixesha elide, enika ukutya okulungileyo nokusebenza.
