Umzekelo we-Ethem

UMZEKELISO WE-TOECUSEE UMZEKELISO LWE-SLWEMER ye-Polymer yenziwa ye-sellyulose 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.

Ngokutsho kohlobo lokufumana indawo yokuhlala, i-Selesese Umzekelo ye-EEST inokwahlulwa ibe yi-ether enye (efana ne-methyl selsulose) kunye ne-ether exutywe (njenge-hydroxyproplow). 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:
