I-HPMC ingahlukaniswa ngezinhlobo ezincibilikayo ngokushesha kanye nezincibilikayo ekushiseni. Lapho amanzi abandayo ehlakazeka ngokushesha futhi ehla emanzini, i-HPMC ingahlukaniswa ngezinhlobo ezincibilikayo ngokushesha kanye nezincibilikayo ekushiseni. Ngalesi sikhathi, uketshezi aluna-viscosity, ngoba i-HPMC ihlakazeka kuphela emanzini, futhi akukho mqondo wangempela wokuncibilika. Ngemva kwemizuzu engaba ngu-2, i-viscosity yoketshezi ikhula kancane, ikhiqize isixazululo se-colloid esicacile nesicwebezelayo. Lapho izinto ezishisayo ze-organic solvent ziqoqana emanzini abandayo, zingahlakazeka ngokushesha emanzini ashisayo futhi zichitheke emanzini ashisayo. Lapho izinga lokushisa elizungezile lehliswa liye ezingeni elithile lokushisa, i-viscosity izokwenzeka kancane kancane kuze kube yilapho kukhiqizwa isixazululo se-colloidal esicwebezelayo esicwebezelayo esiphelele. Uhlobo lwe-solvent ye-organic eshisayo lusetshenziswa kuphela ku-powder ne-mortar yangaphakathi ye-wall putty. Ku-superglue ye-liquid kanye ne-coatings, kunenqwaba yabantu abangakwazi ukusetshenziswa. Uhlobo lwe-quick - solubility lunesigaba sohlelo lokusebenza olujwayelekile. Lungasetshenziswa njenge-interior wall putty powder ne-mortar, kanye ne-liquid superglue yayo ne-coatings. Akukho mthetho.
Ukuncibilika kwamanzi ashisayo: ngoba i-HPMC emanzini ashisayo ayincibiliki, ngakho-ke i-HPMC ekuxhumaneni kokuqala ingahlakazeka ngokulinganayo emanzini ashisayo, bese incibilika ngokushesha lapho iphola. Izindlela ezimbili zakudala zichazwa kanje:
1) Faka amanzi ashisayo owadingayo esitsheni bese uwafudumeza kufike ku-70℃. Hlanganisa kancane kancane, engeza i-hydroxypropyl methyl cellulose kancane kancane, kancane kancane i-HPMC intanta emfuleni, bese ukhiqiza kancane kancane i-sludge efrijini ekuxubeni.
2) Faka ingxenye yesithathu noma ingxenye yesithathu yamanzi esitsheni, uyifudumale ifike ku-70℃, uyifudumale ifike ku-70℃ ukuze usakaze i-HPMC, bese ulungisa udaka lwamanzi ashisayo; Amanzi abandayo asele abe esefakwa kudaka olushisayo bese exutshwa nengxube yangemuva kokupholisa.
Indlela yokuxuba i-powder: I-HPMC powder ene-blender nezinye izithako eziningi zamakhemikhali ze-powder ingxube eyanele, bese ufaka amanzi ukuze incibilike. Ngalesi sikhathi, i-HPMC ingancibilika uma kungekho ukuhlangana, ngoba ekhoneni ngalinye elincane kuphela i-HPMC powder encane, lapho amanzi ezoncibilika khona manjalo — lolu hlobo lwendlela luwukusetshenziswa nje kwabakhiqizi be-putty wall putty kanye ne-mortar. [HPMC] njenge-ejenti yokuqinisa kanye ne-ejenti yokuthambisa ku-mortar putty wodonga lwangaphakathi.
Lokhu ukudabuka okwenziwa yi-hydroxypropyl methyl cellulose (HMPC) okuvamile, okuseduze ne-viscoelastic substance (ikakhulukazi i-mucin) lapho kukhala. Kunamathela ebusweni beso ngokumuncwa kwe-polymer, futhi kulingisa indima ye-conjunctival mucin, ukuze kuthuthukiswe isimo esinciphile se-mucin esweni futhi kwandiswe umphumela wokumanzisa we-cornea.
Ku-putty powder, ukuqina, ukugcinwa kwamanzi kanye nokwakhiwa kwemisebenzi emithathu. Ukuqina, i-cellulose ingaqiniswa ibe yi-suspension, ukuze isixazululo sihlale sifana phezulu naphansi njengendima yokulwa nokugeleza. Ukugcinwa kwamanzi: yenza i-putty powder yome kancane, i-calcium empunga esiza ekusebenzeni kokusabela kwamanzi. Ukwakhiwa: ukuthambisa kwe-cellulose, kungenza i-putty powder ibe nokwakhiwa okuhle. I-HPMC ayihlanganyeli kunoma yikuphi ukusabela kwamakhemikhali, kodwa idlala indima yokusekela kuphela.
Upende wokuthungwa uguquguqukayo kakhulu ekukhetheni umbala, futhi ungafinyelela umphumela omuhle kakhulu wokuklama ngobuciko, futhi upende wamatshe wangempela ekufuneni okufana nokuphila kwemvelo, ungcono kunopende wokuthungwa, ngamunye unamandla awo. Upende wokuthungwa kanye ne-lacquer enkambisweni yokukhiqiza, ukuze silondoloze umbala wokuqala unomphela, ngokuvamile enkambisweni yokugcina, kufanele sisebenzise i-varnish (uwoyela olula) ukuze sifafaze ukuze sivikele umphumela wabo wobuciko noma umphumela wamatshe.
I-Lacquer, upende wokuthungwa uwuhlobo lopende, olusetshenziswa kakhulu ekuhlobiseni udonga. Iwebhusayithi esemthethweni yedaka le-diatom yemvelo ifingqa umehluko phakathi kopende wokuthungwa kanye ne-lacquer, upende wokuthungwa kanye ne-lacquer indlela yokuhlukanisa, okulandelayo okuqondile ukubona umehluko phakathi kopende wokuthungwa kanye nopende wokuthungwa.
Amanani aphezulu e-latex ekhwalithi ephezulu, abakhiqizi ukuze bonge izindleko, mane nje bangeze inani elincane le-emulsion, ngemuva kokwenza ifilimu eyomile yopende wetshe ikhululeke, ukuminyana okwanele akukwanele, ifilimu yopende ibanzi kakhulu, izinga lokucindezela liyancishiswa, uma ihlangabezana nesimo sezulu esinemvula isikhathi eside, imvula izongena efilimu yopende, empeleni ipende letshe limhlophe.
Abanye abakhiqizi ekukhiqizeni i-lacquer, bavame ukwengeza i-carboxymethyl cellulose eningi, i-hydroxyethyl cellulose njenge-thickener, lezi zinto zincibilika emanzini noma zi-hydrophilic, ifilimu yokumboza eshiywe ungqimba, inciphisa kakhulu ukumelana kwamanzi kwengubo.
