Isiphumo sokuqaqamba kwe-ether sete

I-seluplose ether i-Ethew i-Eathews i-Eatows i-orrd emanzi ngohlobo oluhle kakhulu, olunokunyusa kakhulu ubuchule obuphakathi phakathi kodaka olumanzi kunye nomaleko we-Anti Isetyenziswe ngokubanzi kwi-Plaphu, iNkqubo yangaphandle yodonga lwangaphandle kunye nesitena sibopha ubuthongo. Isiphumo sokuqaqamba kwe-ether yeselselose sinokwandisa i-homogeneity kunye nokuchasana nokusasazeka kwezinto ezixubeneyo ezixubileyo, ukulibazisa, inkitha yekhonkrithi, kwaye inokusetyenziswa kwikhonkrithi ye-fible, kwaye isebenza kwikhonkrithi yekhonkrithi.

I-Seley Sether inyusa ukugcinwa kwezinto ezisekwe kwimo yesamente kwi-viscofity yesisombululo se-Selese. Isalathiso se "Viscosity" sihlala sisetyenziselwa ukuvavanya i-viscofity yesisombululo se-Selese. I-viscosity ye-etelulose ether ngokubanzi ibhekisa kwisisombululo se-selsulose ye-selselose kunye noxinzelelo oluthile (njenge-2%). Isantya (okanye inqanaba lokujikeleza, elinje nge-20 rpm), ixabiso le-viscosity elilinganiswe ngesixhobo sokulinganisa esichaziweyo (njengokubonisa okujikelezayo).

I-Viscosity yipharamitha ebalulekileyo yokuvavanya intsebenzo ye-seluplose ether. Ukuphakama kwe-viscosity yesisombululo se-Selese seSeluplose, okungcono ukubonwa kwezinto ezisekwe kwimo yesamente, kungcono ukunamathela kwindawo ekrwada, kwaye yomelele amandla okulwa kunye nokuchasana nokunxaxha. Ukuba uVickosity wayo uphakame kakhulu, kuya kuchaphazela ulwelo kwaye usebenza ngezinto ezisekwe kwisamente (njengokunamathela kwindawo yokubeka phantsi ngokwakhiwa ngomatshini wokwakha). Ke ngoko, i-vickosity ye-seluplose i-ether esetyenziswayo kudaka oluxubeneyo luhlala luyi-15,000 ~ 60,000 MPA. I-S-1, Ukuziqulatha udaka kunye nokuzibandakanya kwikhonkrithi, efuna ulwelo oluphezulu, lufuna uVeksi ophantsi lwe-Selese.

Ukongeza, isiphumo esihlekisayo sother seseluplose Ukonyusa imfuno yamanzi yezinto ezisekwe kwizixhobo, ngaloo ndlela kunyusa isivuno sodaka.

I-viscosity yesisombululo se-selsulose i-sellese ixhomekeke kwezi zinto zilandelayo:

Ubunzima bemolekyuli (okanye inqanaba le-polymerizazazation) kunye nokugxininiswa kwe-Itelulose Ether, iqondo lobushushu lesisombululo, inqanaba lovavanyo.

I-1. Inqanaba eliphezulu le-polymerization ye-seluplose i-ether, enkulu ubunzima bemolekyuli, kunye nokuphezulu kwesisombululo sayo esinamandla;

2. Ukuphakama kwethamo (okanye uxinzelelo) lwe-selsulose ether, okuphezulu kwe-viscofity yesisombululo esibonakalayo, kodwa kuya kuthathelwa ingqalelo ukukhetha umthamo ofanelekileyo xa usebenzisa inyathelo lokuthambana ukuba idosi iphezulu kakhulu;

3. Njengotywala obuninzi, i-viscosity yesisombululo se-Selese seSeluplose siya kuncipha ngokunyuka kobushushu, kunye nokuphakathi kwe-ether eselokhokho, ngakumbi impembelelo yobushushu;

4. Isisombululo se-Seles seluplose sihlala siyi-pseudoplastic, enepropathi yeShear. Inqanaba elikhulu le-Shear ngexesha lovavanyo, iphantsi i-viscofity.

Ke ngoko, ukuhlangana kodaka kuya kuncitshiswa ngenxa yamandla angaphandle, okuyingenelo kulwakhiwo lokukrokra, ngoko ke udaka lunokuba nendlela elungileyo kunye nokumanyanisa ngaxeshanye. Nangona kunjalo, isisombululo se-Selese seLuplose siya kubonisa iimpawu ze-freetonian fluid xa uxinzelelo luphantsi kwaye i-vickosity incinci. Xa uxinzelelo luyenyuka, isisombululo siya kubonisa ngokuthe ngcembe iimpawu ze-pseudoplastic, kunye nokuxinana okuphezulu, ngokucacileyo i-pseudoplastity.
