A na-eji ngwaahịa ciment, dị ka ihe, ngwa agha, na ihe ndị ọzọ na-ewu ụlọ, na-ejikarị ụlọ ọgbara ọhụrụ. Ahyọkọ mkpụrụ osisi (dị ka hydropyylthylthylthylthyl), hydroxyethyl methylcelllose (wdg), wdg) bụ ihe mgbakwunye nwere ike ime ka arụmọrụ ngwaahịa ciment. Iji mezuo ihe ndị a dị mma, ọ dị oke mkpa na Master ma jikwaa arụmọrụ nke eyers cellulose.
1. Ihe Njirimara nke Ọma na ọrụ nke Ether
Ethsgbọ elu cellugul bụ klas nke kemịkal nke sellose, nke otu hydroxy ji dochie anya site na otu mmeghachi omume. Enwere ike ịhazi ụdị dị iche iche nke mkpụrụ osisi cellose dị ka ụdị na ọnụ ọgụgụ nke ndị nnọchianya, ụdị nke ọ bụla nwere ọrụ dị iche na ngwaahịa ciment.
Viscosity nke eyers:
Vieo Voluty nke Arters na-emetụta rhiology na nkwụsi ike nke ciment. Ahịhịa mkpụrụ ndụ cellcosise nwere ike ime ka njigide mmiri dị elu nwere ike ime ka njigide mmiri dị elu ma nwee ike belata ọnya ya. Ndị na-ahụ maka vieoles na-enye ohere na-enyere aka ime ka ọ dị mma na mmiri.
Ogo nke nbanye (DS) na ndọtị molaị (ms):
Ogo nke dochie anya na ihe eji egbochi mmebe ihe nke mkpụrụ ndụ na-ekpebi onye na-edozi ya na viscosity nke ihe ngwọta. Ogo dị elu nke ihe nnọchianya na akara ngosi dị elu nwere ike ime ka njigide mmiri dị elu na nkwụsi ike nke eyers.
Solublity nke eyers celluluse:
Ọnụego mgbasa mkpụrụ na-eso ụzọ nke ndị eutthers na-emetụta otu ciment Tame. Eyers cellugul nwere ezigbo solublity nwere ike ibupụta otu ihe ngwa ngwa ngwa ngwa, si otú a hụ na otu na nkwụsi ike nke mado.
2. Họrọ Ethers Cellugul
Ọnọdụ ngwa dị iche iche nwere arụmọrụ arụmọrụ dị iche iche maka eyers cellugul. Chohọrọ ụdị ziri ezi na nkọwapụta nke mkpụrụ osisi celdigul nwere ike bulite arụmọrụ ngwaahịa nke ciment:
Binders:
Na ngwa dị ka taịlị ndị na-agba oyi, ndị dị elu cellsity sel na-enwe ike ịnye nghazi nke ọma ma nwee ike ịgbanye arụmọrụ dị mma na ike nke na-adịgide adịgide.
Ihe eji eme mmiri:
Na ngwa agha nke onwe ya na ebe a na-adọba ụgbọala na-adọkpụ, eyers cellususe nwere akwa mmiri dị elu (dịka hemsc). Nnukwu ụdị mmiri na-enyere aka igbochi mpụ mmiri na-egbu egbu, si otú ahụ na-eme ka mmeghachi omume hydration zuru oke na oge na-arụ ọrụ ogologo oge.
Na-agba ume
Evethers etred na-eme ka ike nke ngwaahịa ciment kwesịrị inwe ezigbo nchụsa ma na-agafe agafe iji kwalite otu matrif.
3. Jiri usoro mgbakwunye
Na-achịkwa mgbakwunye nke cellose na ngwaahịa ciment dị mkpa iji bulie arụmọrụ ya nke ọma. Ihe ndị a bụ ọtụtụ ụzọ kachasị mma ejikarị ngwa ọgụ:
Usoro nke Preyima:
Mix celllulose eat nwere ntụ ntụ ndị ọzọ tupu oge eruo. Usoro a ga - ezere nguzo nke agglomeration nke cellulose ether mgbe ị na-akpọtụrụ mmiri, si otú a hụ na mgbasa ozi ya na slurry.
Usoro Mix:
Tinye cellulose ether gaa na ciment slurry nke nta nke nta. Usoro a dabara adaba maka ọnọdụ ebe ikuku na-efe efe efegharị ngwa ngwa ma na-enyere aka ịmalite nkwụsịsi ike.
Eserese Egementedzọ:
Na usoro ịkwadebe ciment, na-agbakwunye cellose ether nwere ike hụ na nkesa ya niile na usoro nkwadebe ma belata agglomeration.
4. Njikwa ihe mpụga
Ihe mpụga dị ka okpomọkụ, ọnụ ahịa PH dị, yana ọnụego nwere mmetụta dị ukwuu na arụmọrụ nke cellulose ether.
Njikwa okpomoku:
Ngalaba na viscosity nke cellose eather nwere mmetụta dị nro okpomọkụ. Oke okpomọkụ na-enyere aka na-enyere aka na-enyere ya aka na ngwa ngwa, mana ọ nwekwara ike ime ka viccosity nke ihe a ga-agbadata. Ekwesịrị idozi ọnọdụ okpomọkụ dịka ọmụmaatụ ngwa akọwapụtara iji hụ na arụmọrụ kachasị mma na arụmọrụ kachasị mma.
Mgbanwe plọg: uru nke ciment ciment na-abụkarị na ala alkaline dị elu, ebe ndọlite na viscosity nke cellulose na-agbanwe agbanwe na mgbanwe nke mkpụrụ osisi nke mkpụrụ osisi. Na-achịkwa uru plọ akụ kwesịrị ekwesị nwere ike ime ka arụmọrụ nke cellulose ether.
Ọnụego ọnụego: Ọnụego mkpali ahụ na-emetụta mmetụta mgbasa nke sel na ciment pastema. Ọnụego mmụba dị elu nwere ike ibute mmeghe ikuku na nchịkọta nke cellose eather, ebe ọnụego na-akpali akpali na-enyere aka ikesa ya ma belata cell.
5. Nnyocha nyocha na aro ndị bara uru
Site na nyocha nke ikpe, anyị nwere ike ịghọtakwuo ngwa na atụmatụ njikarịcha nke cellulose na ngwaahịa ciment dị iche iche:
Ngwongwo tile dị elu: Mgbe ụlọ ọrụ na-emepụta ihe nrapado dị elu, a hụrụ na njigide mmiri dị elu, a chọpụtara na mmiri mmiri mbụ ezughi oke, nke na-ebute ike na njikọ ahụ. Site na iwebata oke mmiri na-ejigide ya na usoro mgbakwunye ya na mgbakwunye ya (iji usoro nke premix), njigide mmiri na ike mmiri na-aga nke ọma.
Onwe-ya nke onwe ya, ebe a na-ahụ maka onwe ya na-enweghị ọrụ na-enweghị oke mmiri na elu dị mma na-agagharị. Site na ịhọrọ ọnụego na-enweghị viscosity na njikwa okpomọkụ ahụ, ihe na-agụ mmiri na arụmọrụ nke slurry a na-eme ka ọ dị mma.
Na-achịkwa arụmọrụ nke cellulose na ngwaahịa ciment bụ isi ihe ga - eme ka ọ dị mma arụmọrụ na ogo iwu. Site na ịhọrọ ụdị cellulose eather dị mma, na-ejikwa ihe mgbakwunye na-emetụta ihe dị ka mmiri ciment, adhesion, na mmiri nwere ike ịka mma. N'ime ihe bara uru, ọ dị mkpa iji bulie ma mezie ihe ojiji nke cellose na-ekiri ihe ụfọdụ akọwapụtara na ntinye akwụkwọ iji rụpụta nsonaazụ kacha mma.
