Ukwakha i-hydroxypropyl methyl cellulose ekhethekileyo ukunqanda ukungena kokufuma eludongeni, kuya kuba ngumlinganiselo ofanelekileyo wokufuma onokuhlala kwisamente yodaka ukuvelisa ukusebenza kakuhle emanzini kunye nendima ye-hydroxypropyl methyl cellulose eludongeni inokulingana ne-viscosity, ukuphakama kwe-viscosity ye-hydroxypropyl methyl cellulose ukugcinwa kwamanzi kuya kuba ngcono.
Nje ukuba ukufuma kwe-hydroxypropyl methyl cellulose kuphezulu kakhulu, ukugcinwa kwamanzi e-hydroxypropyl methyl cellulose kuya kuncipha, kwaye kuya kukhokelela ngokuthe ngqo ekusebenzeni kakuhle kwe-hydroxypropyl methyl cellulose. Sikwaqhelene nezinto ziya kuba lula ngakumbi ukwenza iimpazamo, kufuneka sihlale sihlaziyekile, siya kufumana iziphumo ezingalindelekanga.
I-viscosity ebonakalayo yisalathiso esibalulekileyo se-hydroxypropyl methyl cellulose. Iindlela eziqhelekileyo zokulinganisa ukulinganisa i-viscosity ejikelezayo, ukulinganisa i-capillary viscosity kunye ne-viscosity yokuwa.
Ngaphambili, i-hydroxypropyl methyl cellulose yayimiselwe ngumlinganiselo we-capillary viscosity, usebenzisa i-viscometer ye-Uhnscher. Isisombululo somlinganiselo sikholisa ukuba sisisombululo esinamanzi sesi-2, kwaye ifomula ithi: V=Kdt. I-V yi-viscosity ngemizuzwana, i-K yinto engaguqukiyo ye-viscometer, i-D yi- density kwiqondo lobushushu elingaguqukiyo, kwaye i-T lixesha elithathayo ukusuka phezulu ukuya ezantsi kwi-viscometer ngemizuzwana. Le ndlela yokusebenza inzima ngakumbi, ukuba kukho izinto ezingaxutywanga, kulula ukubangela iimpazamo, kunzima ukuchonga umgangatho we-hydroxypropyl methylcellulose.
Ingxaki yokwakha i-glue stratification yingxaki enkulu edibana nabathengi. Okokuqala, ingxaki yezinto eziluhlaza kufuneka ithathelwe ingqalelo ekwakheni i-glue stratification. Isizathu esikhulu sokwakha i-glue stratification kukungahambelani phakathi kwe-polyvinyl alcohol (PVA) kunye ne-hydroxypropyl methylcellulose (HPMC). Isizathu sesibini kukuba ixesha lokuxuba alanele; Kukwakho ukusebenza kweglue yokwakha akulunganga.
Kulwakhiwo lweglue, i-instant hydroxypropyl methylcellulose (HPMC) kufuneka isetyenziswe kuba i-HPMC isasazwe kuphela emanzini kwaye ayinyibiliki ngokwenene. Malunga nemizuzu emi-2, i-viscosity yolwelo ikhula kancinci, yenze i-colloid ebonakalayo ebonakalayo.
Iimveliso ezishushu ezinyibilikayo, kumanzi abandayo, zinokusasazwa ngokukhawuleza emanzini ashushu, zinyamalale emanzini ashushu, xa ubushushu buhla kwiqondo elithile lobushushu, i-viscosity ibonakala kancinci, de kube yi-colloid ebonakalayo ebonakalayo. I-Hydroxypropyl methylcellulose (HPMC) kwi-glue yesakhiwo isixa esongezelelweyo sinconywa kwi-2-4kg.
I-Hydroxypropyl methyl cellulose (HPMC) kwisakhiwo seglue ukuzinza kweekhemikhali, i-mildew, impembelelo yokugcina amanzi ilungile, kwaye ayichaphazeli utshintsho lwe-PH, i-viscosity evela kwi-100 000 S - 200 000 S ingasetyenziswa. Kodwa kwimveliso ayikho phezulu i-viscosity ingcono, i-viscosity kunye namandla ebhondi ahambelana ngokungafaniyo, ukuphakama kwe-viscosity, amandla amancinci, ngokubanzi i-100,000S viscosity ifanelekile.
