Zithini iipropathi zebhokisi yebhokisi yebhokisi ye-carboxethyl?

Impendulo: I-carboxymethyl selliese nayo inepropathi eyahlukeneyo ngenxa yamanqanaba ayo afanayo. Inqanaba lokufakwa endaweni, ekwabizwa ngokuba yinqanaba lokuthengiswa kwesiseko, lithetha inani eliphakathi le-H kwizinto ezintathu oh hydroxyl amaqela athatyathwa yiCh2coona. Xa amaqela amathathu e-hydroxyl kwi-ring yaselfowuni ene-0.4 h kwiqela le-hydroxyl endaweni ye-carboxymethyl, inokuchithwa emanzini. Ngeli xesha, kubizwa ngokuba yi-0.4 isidanga sokufaka okanye isidanga sokufaka esiphakathi (isidanga sokufaka i-0.4-12).

Iipropathi zebhokisi ye-carboxymethyl sellyulose:

. Inesisasazi kakuhle kunye namandla okubopha.

. Ikwanobuchule obungaphandle kweoyile kunye ne-wax, kwaye sisimo esomeleleyo.

. Nangona kunjalo, ngaphandle kokukhokela i-acetate, isenokuchithwa kwakhona kwi-Sodium hydroxide, kunye ne-precipitites enje nge-barium, i-iron kunye ne-aluminium inyibilika ngokulula kwi-1% ye-Ammonium ye-Ammonium hydroxide.

. Ngokokujonga, xa ixabiso le-PH liyi-2,5, i-turbidity kunye ne-prippity sele iqalile. Ke ngoko i-25 inokuthathwa njengendawo ebalulekileyo.

(6) Iqondo lobushushu linempembelelo enkulu kuhlobo lwe-viscosity yesisombululo sayo. I-viscosity inciphisa ngokuhambelana xa iqondo lobushushu liphuma, kwaye ngokuchaseneyo. Uzinzo lohlobo lwe-viscosity yesisombululo se-ACTEACE kubushushu begumbi buhlala singaguqukanga, kodwa i-vickosity ingancipha kancinci xa ikhula ngaphezulu kwe-80 ° C ixesha elide. Ngokubanzi, xa amaqondo obushushu engadlulanga kwi-110 ° C, nokuba amaqondo obushushu agcinwa iiyure ezi-3, aze apholelwe ukuya kwi-25 ° C, i-viscosity isabuya kwimeko yayo yoqobo; Kodwa xa iqondo lobushushu lishushu kwi-120 ° C kwiiyure ezi-2, nangona iqondo lobushushu libuyiselwe, i-viscosity ihla nge-18.9%. .

. Ngokubanzi, xa isisombululo se-viscosity esingathathi hlangothi, ukubonwa kwayo akunampembelelo kangako, ngelixa isisombululo se-viscosity, ukuba i-PH iqaqambe, i-viscosity iqala ukuncipha kancinci; Ukuba isisombululo se-vickosity ephezulu siphambuka ekungathathi cala, uVikyusity uya kuncipha. Ukwehla okukhalayo.

. Umzekelo, iyahambelana neglue ye-GLUIC, i-Gum Arabic, i-Glycerin kunye nesitatshi esinyibilikayo. Ikwahambelana neglasi yamanzi, i-polyvinyl utywala, i-urea-fordeddehyde, iMelamine-fouldehydehyde, kodwa ukuya kwinqanaba elincinci.

.

(10) Kukho i-viscofity ezintathu eziza kukhetha ngokwesicelo. I-Gypsum, sebenzisa i-viscosity ephakathi (2% ye-APTEAROOR kwi-300-600Mpas), ukuba ukhetha i-viscofity ephezulu (1%), unokuyisebenzisa kwidosi okanye ngaphezulu), unokuyisebenzisa kwidosi kufuneka ihlise ngokufanelekileyo.

.

. Emva kongcoliseko, i-viscosity iya kuhla kwaye iya kuvela i-maildew. Ukongeza isixa esifanelekileyo sezinto ezigcina phambili kwangaphambili zinokugcina i-viscofity yayo kwaye ikhusele i-raildew ixesha elide. Oogcino olufumanekayo:

Isebenza kangakanani i-hydroxypropyl methylcelcelcelose njengearhente yokugcina amanzi kwi-anhddrite?

Impendulo: I-Hydroxypropyl Methylcelcelcelose iarhente yokugcina amanzi ngamanzi e-Gypsim ye-Gypsim ye-Gypsim. Ngokunyusa umxholo we-hydroxypropyl methylcelcelose. Ukugcinwa kwamanzi kwe-gypsim ye-gypsim yezinto zanda ngokukhawuleza. Xa kungekho manzi iarhente yokugcina amanzi, iqondo lokugcina amanzi le-gypsim lesamente limalunga nama-68%. Xa inani le-arhente yokugcina amanzi yi-0.15%, inqanaba lokugcina amanzi le-gypsim lesamente linokufikelela kwi-90.5%. Kunye neemfuno zokugcina amanzi ze-plaster engezantsi. Umthamo wearhente yokugcina amanzi ungaphezulu kwe-0.2%, ngakumbi ukwandisa idosi, kunye nenqanaba lokugcina amanzi le-gypsim ye-gypsim yesamente enyuka kancinci. Ukulungiswa kwe-Anhhddring Stones. Umthamo ofanelekileyo we-hydroxypropyl methylcelgalose yi-0.1% -0.15%.

Zithini iziphumo ezahlukileyo zeselpulose eyahlukileyo kwi-Plaster yeParis?

Impendulo: Zombini i-carboxymethyl seluplose kunye ne-methyl seluplose zinokusetyenziswa njengamanzi agcina amanzi kwi-caris, kodwa i-carboxymethyl iselcelose iqulathe i-sodim ye-sodim iqulathe i-SODIIS inesiphumo kwaye inciphise amandla e udaka. I-methyl seluplose yeyona nto iphambili kwi-Gypsim ye-Gypsim yeGyppum yokudibanisa ukugcinwa kwamanzi, ukudibanisa ukuqina, ukomeleza, kunye nokufowuna, ngaphandle kokuba idosi inkulu. Iphezulu kune-carboxymethyl sellyulose. Ngesi sizathu, uninzi lwezixhobo zeGypsum zeGypsum zamkela indlela yokudibanisa i-carboethyl seluplose, efana neflethi ye-COXYYMETHTE Ngale ndlela, zombini intsebenzo yokugcina amanzi ye-Gypsim ye-Gypsim ye-Gypsim kunye nentsebenzo ebanzi ye-Gypsim ye-gypsim ye-gypsim yesamente inokuphuculwa, ngelixa ukunyuka kweendleko kugcinwa kweyona ndawo iphantsi.
