I-Cellulose ether inemisebenzi emithathu ilandelayo:
1) Iyakwazi ukujiyisa udaka olutsha ukuthintela ulwahlulo kwaye ufumane umzimba weplastiki ofanayo;
2) Inomsebenzi wokungena komoya kwaye iyakwazi ukuzinzisa amaqamza amancinci afanayo angeniswe kudaka;
3) Njengesixhobo sokugcina amanzi, kuyanceda ukugcina amanzi (amanzi asimahla) kuluhlu olucekethekileyo lodaka, ukuze isamente ibe nexesha elingakumbi lokugalela amanzi emva kokwakhiwa kodaka.
Kumdaka odibeneyo owomileyo, i-methyl cellulose ether idlala indima ekugcinweni kwamanzi, ukuqina kunye nokuphucula ukusebenza kokwakhiwa. Ukusebenza kakuhle kokugcinwa kwamanzi kuqinisekisa ukuba udaka aluyi kubangela isanti, umgubo kunye nokunciphisa amandla ngenxa yokunqongophala kwamanzi kunye ne-cement hydration engaphelelanga; Isiphumo sokutyeba kwandisa kakhulu amandla okwakhiwa kodaka olumanzi, njengesakhono esilungileyo sokuchasa ukuncamathela kwethayile; Ukongezwa kwe-methyl cellulose ether kunokuphucula ngokucacileyo i-viscosity emanzi yodaka olumanzi, olune-viscosity efanelekileyo kwii-substrates ezahlukeneyo, ngaloo ndlela kuphuculwe ukusebenza kodonga lodaka olumanzi kunye nokunciphisa inkunkuma.
Xa usebenzisa i-cellulose ether, kufuneka kuqatshelwe ukuba isixa se-cellulose ether siphezulu kakhulu okanye i-viscosity iphezulu kakhulu, imfuno yamanzi iya kwanda, kwaye ukwakhiwa kuya kuba nzima (i-plastering) kunye nokusebenza kuya kuncitshiswa. I-ether ye-cellulose inokulibazisa ixesha lokumisela i-samente, ngakumbi xa i-dosage iphezulu. Ukongeza, i-cellulose ether iya kuchaphazela ixesha lokuvula, ukuchasana nokuhamba ngokuthe nkqo kunye namandla ebhondi yodaka.
I-ether ye-cellulose efanelekileyo kufuneka ikhethwe kwiimveliso ezahlukeneyo, kwaye imisebenzi yayo ihluke. Ngokomzekelo, i-MC ene-viscosity ephezulu kufuneka ikhethwe kwi-adhesive tile ye-ceramic, enokwandisa ixesha lokuvula kunye nexesha elihlengahlengiswayo, kunye nokuphucula ukusebenza kwe-anti slip; I-MC ene-viscosity ephantsi kufuneka ikhethwe kwi-self leveling mortar ukuze igcine ukumanzi kodaka, kwaye idlala indima ekuthinteleni i-delamination kunye nokwahlula kunye nokugcinwa kwamanzi. I-ether ye-cellulose efanelekileyo iya kumiselwa ngokweengcebiso zomenzi kunye neziphumo zovavanyo ezihambelanayo.
Ukongeza, i-cellulose ether inefuthe lokuzinzisa i-foam, kwaye ukubunjwa kwefilimu kwangaphambili kuya kubangela ukunyuswa kodaka. I-microstructure ye-cellulose ether kwi-adhesive ye-ceramic esanda kuxutywa kunye nokuqina kwetayile ye-ceramic yaphononongwa yiYunivesithi yaseBern kunye ne-National Starch Chemical Company eSwitzerland. Uvavanyo lwentsimi oluboniswe kuMzobo lufumene ukuba i-cellulose ether izinzile amaqamza kudaka olutsha ngokwenza ifilimu. Ezi filim ze-cellulose ether zisenokuba zenziwe ngexesha okanye emva nje kokuzanyazanyiswa, kwaye i-re dispersible rubber powder ayikaqalisi ukwenza iifilimu. Undoqo emva kwesi siganeko ngumsebenzi ongaphezulu we-cellulose ether. Njengoko amaqamza angeniswa yi-agitator ngendlela ebonakalayo, i-cellulose ether ngokukhawuleza ithatha ujongano phakathi kwamaqamza kunye nodaka lwesamente ukwenza ifilimu. Ezi filimu zisemanzi, ngoko ziguquguquka kakhulu kwaye zinyanzeliswa, kodwa umphumo we-polarization uqinisekisa ngokucacileyo ukucwangciswa kocwangco lweeamolekyu zabo. Kamva, ezi filimu ze-cellulose ether zinokufumaneka kumda we-pores phantsi kwe-microscope ye-electron yokuskena, njengoko kuboniswe kuMzobo.
Njengoko i-cellulose ether iyipolymer enyibilikayo emanzini, iya kufudukela kumphezulu apho udaka lunxibelelana nomoya kunye nokuphuma kwamanzi kumdaka kudaka olutsha ukuze kuphuculwe, okukhokelela ekukhutshweni kwe-cellulose ether kumphezulu wodaka olutsha. Njengomphumo wesikhumba, ifilimu edibeneyo iqulunqwa kwindawo yodaka, eya kunciphisa ixesha lokuvula lomdaka. Ukuba i-tile ye-ceramic ifakwe kumphezulu wodaka ngeli xesha, ifilimu iya kusasazwa ngaphakathi kwendawo yodaka kunye ne-interface phakathi kwe-tile ye-ceramic kunye nodaka, ngaloo ndlela inciphisa amandla ebhondi kwixesha elizayo. Ukukhutshwa kwe-ether ye-cellulose kunokuncitshiswa ngokulungelelanisa i-formula, ukukhetha i-ether ye-cellulose efanelekileyo kunye nokongeza ezinye izongezo.
I-Youngcel HPMC / MHEC isetyenziswa ngokubanzi njenge-Chemical Auxiliary Agent ye-Tile Adhesive, i-Cement Plaster, i-Dry mix mortar, i-Wall putty, i-Coating, i-Detergent kunye nokunye.Kwaye sinokukunika ixabiso eliphantsi kunye nomgangatho ophezulu.
Iimveliso zethu zithandwa eYiputa, eRashiya, eMzantsi Afrika, kuMbindi Mpuma, eTurkey, eVietnam, eFransi, eItali, eSingapore, eBangladesh, e-Indonesia, eMzantsi Melika njalo njalo. Enkosi kwangaphambili kwaye wamkelekile ukuba uqhagamshelane.
