Ukugcinwa kwamanzi kwei-cellulose ethers
Ukugcinwa kwamanzi kodaka kubhekiselele kubuchule bodaka ukugcina nokutshixa ukufuma.Iphezulu i-viscosity ye-cellulose ether, ngcono ukugcinwa kwamanzi.Ngenxa yokuba isakhiwo se-cellulose sine-hydroxyl kunye neebhondi ze-ether, i-athomu ye-oksijini kwi-hydroxyl kunye neqela le-ether bond linxulunyaniswa ne-molecule yamanzi ukwenza iibhondi ze-hydrogen, ukuze amanzi akhululekile abe ngamanzi abophekileyo kunye nomoya wamanzi, ngaloo ndlela edlala indima yamanzi. ugcino.
Ukunyibilika kwei-cellulose ether
1. I-coarser cellulose ether ichithwa ngokulula emanzini ngaphandle kwe-agglomeration, kodwa izinga lokuchithwa licotha kakhulu.I-cellulose ethersphantsi kwe-60 mesh zinyibilika emanzini malunga nemizuzu engama-60.
2. Iinqununu ezintle ze-cellulose ether zihlakazwa ngokulula emanzini ngaphandle kwe-agglomeration, kwaye izinga lokuchithwa liphakathi.Ngaphezulu kwe-80 meshi-cellulose etheriyachithwa emanzini malunga nemizuzu emi-3.
3. I-ultra-fine cellulose ether isasazeka ngokukhawuleza emanzini, inyibilika ngokukhawuleza, kwaye yenza i-viscosity ekhawulezayo.Ngaphezulu kwe-120 meshi-cellulose etheriyachithwa emanzini malunga nemizuzwana eyi-10-30.
Okukhona amasuntswana e-cellulose ether, kokukhona agcina amanzi ngcono.Umphezulu orhabaxaI-Cellulose Ether HEMCInyibilika ngokukhawuleza emva kokudibana namanzi kwaye yenza i-gel phenomenon.I-glue igubungela izinto zokuthintela iimolekyuli zamanzi ukuba zingaqhubeki nokungena, kwaye ngamanye amaxesha azikwazi ukuchithwa ngokulinganayo kwaye zichithwe emva kwexesha elide lokuphazamiseka, ukwenza isisombululo se-flocculent e-turbidized okanye i-caking.Iinqununu ezintle zihlakazeke ngokukhawuleza kwaye zidibanise ngokudibanisa namanzi ukuze zenze i-viscosity efanayo.
Umoya we-cellulose ether
I-aeration ye-ether cellulose yenziwa ikakhulu ngenxa yokuba i-ether yeselulosi ikwaluhlobo lwe-surfactant, kwaye umsebenzi wokudibanisa ubuso be-cellulose ether wenziwa ikakhulu kujongano oluqinileyo lwe-gas-liquid, okokuqala ngokwazisa amaqamza, kulandele ukusasazwa kunye nokumanzisa.I-cellulose ethers iqulethe amaqela e-alkyl, anciphisa kakhulu ukuxinana komphezulu kunye namandla angaphakathi kwamanzi, okwenza isisombululo samanzi sivelise amaqamza amancinci amaninzi avaliweyo ngexesha lokuphazamiseka.
I-gelatincity ye-cellulose ethers
Emva kokuba i-cellulose ether ichithwe kumdaka, iqela le-methoxy kunye neqela le-hydroxypropyl kwikhonkco le-molecular liya kusebenzisana ne-calcium kunye ne-aluminium ion kwi-slurry ukwenza i-gel viscous kwaye igcwalise i-void ye-cement mortar, ukuphucula ukuxinaniswa kodaka. udaka kunye nokudlala indima yokuzaliswa okuguquguqukayo kunye nokuqinisa.Nangona kunjalo, xa i-matrix edibeneyo icinezelwe, i-polymer ayikwazi ukudlala indima exhasayo eqinile, ngoko ke amandla kunye nomlinganiselo wokugoba wodaka lwehla.
Iipropati zokwenza ifilimu ye-cellulose ether
Ifilimu ye-latex encinci yenziwa phakathi kwe-cellulose ether kunye neengqungquthela ze-samente emva kwe-hydration, enefuthe lokutywinwa kunye nokuphucula ukomiswa komphezulu wodaka.Ngenxa yokugcinwa kakuhle kwamanzi kwi-cellulose ether, iimolekyuli zamanzi ezaneleyo zigcinwa ngaphakathi kodaka, ukwenzela ukuba kuqinisekiswe ukuhanjiswa kunye nokuqina kwesamente kunye nophuhliso olupheleleyo lwamandla, ukuphucula amandla okubopha udaka, kunye nokuphucula ukubumbana komdaka, ukwenzela ukuba udaka lube neplastiki elungileyo kunye nokuguquguquka, kunye nokunciphisa i-shrinkage deformation yodaka.
