Isiphumo sokuthambisa se hydroxypropyl methylcelcelce

I-HydroxyPOpyl Methylcelceluplose Endose Evedows Emanzi Ngobukhoboka obugqwesileyo, ezinokunyusa umgangatho ophakathi komsebenzi omanzi kunye nokuphucula indlela yokulwa nokuchasana nodaka. Ebudeni. Isiphumo sokuqaqamba kwe-ether ese seluplose sinokwandisa i-homogeneity kunye nokukwazi ukusasazeka kwezinto ezisisiseko zesamente, ukuphanga ukuthengiswa kwekhonkrithi, kwaye kunokusetyenziswa kwikhonkrithi yekhonkrithi, kwaye kungasebenzi kakuhle.

I-Hydroxypropyl Methylcelcelcealuplose yonyusa i-viscofity yezixhobo ezisekwe kwi-viscosity yesisombululo se-Selese. I-viscosity yesisombululo se-selsulose i-selsulose idla ngokuvavanywa yi-Index "Viscosity". I-viscosity ye-selsulose ether ngokubanzi ibhekisa kuxinzelelo oluthile (njenge-2%) yesisombululo se-selsulose kwiqondo lokulinganisa elilinganayo (okanye i-20 ° C) phantsi kwemeko yesantya (okanye ireyithi yojikelezo, njenge-20 rpm).

I-Viscosity yipharamitha ebalulekileyo yokuvavanya intsebenzo ye-seluplose ether. Ukuphakama kwe-viscofity ye-Hydroxypropyl Methylcelcelse Stols, kungcono ukuboniswa kwezinto ezisekwe kwisamente, okungcono ukunamathela kwindawo ekrwada, kungcono ubuchule obuchasene nobuchasayo. Yomelele, kodwa ukuba i-viscosity yayo inkulu kakhulu, iya kuchaphazela ulwelo kwaye isebenza ngezinto ezisekwe kwisamente (njengokunamathela kwindawo yokwakhiwa kwendawo). Ke ngoko, i-vickosity ye-seluplose i-ether esetyenziswayo kudaka oluxubeneyo luhlala luyi-15,000 ~ 60,000 MPA. I-S-1, ukuQalisa ngokwakho

Ukongeza, isiphumo sokuqaqamba kwe-hydroxypropyl methylcelcelceluplose yonyusa imfuno yamanzi yezinto ezisekwe kwisamente, ngaloo ndlela yandisa isivuno sodaka.

Uhlobo lwe-viscosity ye-hydroxypropyl methylcelcelse isisombululo sixhomekeka kwezi zinto zilandelayo:

I-selsulose ether molecular yobunzima (okanye inqanaba le-polymerizazazation) kunye nobushushu besisombululo, ireyithi yehear, kunye neendlela zovavanyo.

1. Inqanaba eliphezulu le-Polymerization ye-Teluplose Ether, enkulu ubunzima bemolekyuli, kunye nokupheliswa kwesisombululo sayo esinamandla;

2. Ukuphakathi kwethamo (okanye uxinzelelo) lwe-Selersese Ether, okuphezulu kwe-viscosity yesisombululo esinamandla, kodwa kufuneka ihlawulwe ukukhetha umthamo ofanelekileyo xa uyisebenzisa, ukuze ichaphazele ukusebenza kwekhonkrithi kunye nekhonkrithi;

3. Njengotywala obuninzi, i-viscosity yesisombululo se-Selese seSeluplose siya kuncipha ngokunyuka kobushushu, kunye nokuxinana okuphezulu kwe-taryuese, kokukhona ifuthe lobushushu;

I-4. I-Selese Stose Scovals ihlala iPseudoplastics nge-Shear I-Shearties. Ngaphezulu kwinqanaba le-Shear ngexesha lovavanyo, iphantsi i-viscofity.

Ke ngoko, ukuhlangana kodaka kuya kuncitshiswa ngenxa yesenzo samandla angaphandle, okuyingenelo kulwakhiwo lokuphumla kodaka, ukuze udaka lunokubakho ngokusebenza okuhle kunye nokusebenzisana ngaxeshanye. Nangona kunjalo, xa uxinzelelo lwe-Selese yeSelsulose iphantsi kakhulu kwaye i-vickosity incinci kakhulu, iya kubonisa iimpawu zolwelo lwaseNewtonian. Xa uxinzelelo luyenyuka, isisombululo siya kubonisa ngokuthe ngcembe iimpawu ze-pseudoplastic, kwaye ngaphezulu koxinzelelo, eyona nto icacileyo yePseudoplastity.
