Umbuzo okhawulezayo malunga ne-seluplose

I-01. Ukusetyenziswa okuphambili kwe-selsulose ether hpmc?

I-HPMC isetyenziswe ngokubanzi kudaka lokwakha, ipeyinti esekwe emanzini, i-resin yokwenziwa, i-ceramic, i-ceramic, i-ceramic, ukutya, i-cosmetics, icuba, kunye namanye amashishini. Yahlulahlulwe yayibanga lokwakha, iBanga lokutya, iBakala laseMachiza, iBakala lezoMveliso ye-PVC kunye neBanga leMfundo kunye neBanga leShemicamical Chemical.

02. Zithini izinto zokuhlelwa kweseli?

Iiselseses eziqhelekileyo yi-MC, i-HPMC, MHC, CMC, Hec, EC
Phakathi kwazo, i-hec kunye ne-CMC isetyenziswa kakhulu kwi-cayishini esekwe emanzini,
I-CMC inokusetyenziswa nakwi-ceramics, intsimi yeoyile, ukutya kunye namanye amasimi
I-EC isetyenziswe ikakhulu kumayeza, i-elektroniki yesilivere kunye namanye amasimi
I-HPMC yahlulahlulwe yanguluhlobo oluhlukeneyo kudaka, amayeza, ukutya, ishishini le-PVC, iimveliso zemichiza zemichiza kunye namanye amashishini

03. Nguwuphi umahluko phakathi kwe-HPMC kunye ne-MHEC kwisicelo?

Iipropathi zezi ntlobo zimbini zeselfowuni zifana, kodwa iqondo lobushushu ephezulu, ngakumbi ehlotyeni xa iqondo lobushushu liphezulu, kwaye umsebenzi wokugcinwa kwamanzi ungcono kune-HPMC phantsi kweemeko zobushushu obuphezulu.

04. Ugweba njani ngokugqibeleleyo umgangatho we-HPMC?

1) Nangona ubumhlophe abunakufumanisa ukuba i-HPMC kulula ukuyisebenzisa, kwaye ukuba i-Whitering iyongezwa kwinkqubo yemveliso, umgangatho uya kuchaphazeleka, kodwa uninzi lweemveliso ezilungileyo lugwetywe ngokubonakala.
2) Ukukhanya kokukhanya: Emva kokunyibilikisa i-HPMC emanzini ukwenza i-colloid ebonakalayo, jonga ukukhanya kwayo. Okungcono ukuguqula ukukhanya, umbandela ongaphantsi kwento eninzi, kwaye umgangatho ulungile.
Ukuba ufuna ukugweba ngokuchanekileyo umgangatho weselUlose, eyona ndlela inokuthenjwa kukusebenzisa izixhobo zobungcali kwilabhoratri yobungcali yovavanyo. Ezona zikhombisi ziphambili zibandakanya i-visofity, iqondo lokugcina amanzi, kunye nomxholo we-ash.

05. Ungayilinganisa njani i-viscosity yesellulose?

Inqaku eliqhelekileyo kwintengiso yasekhaya eselfowuni yi-NDJ, kodwa kwimakethi yamanye amazwe, abavelisi abahlukeneyo bahlala besebenzisa iindlela ezahlukeneyo zokuvavanya. Ezona ziqhelekileyo ziyi-Brookbled RV, i-hoppler, kwaye kukwakho nezisombululo zokufunda ezahlukeneyo, ezahlulwe zangama-1% isisombululo kunye nesisombululo se-2%. Iimpawu ezahlukeneyo zokubonisa kunye neendlela ezahlukeneyo zokuchonga zihlala zikhokelela kumahluko okhutshelweyo amatyeli aliqela okanye amaxesha amaninzi kwi-viscovity iziphumo.

06. Nguwuphi umahluko phakathi kohlobo lwe-HPMC ngokukhawuleza kunye nohlobo olushushu?

Iimveliso ze-HPMC zibhekisa kwiimveliso ezisasaza ngokukhawuleza emanzini abandayo, kodwa kufuneka ziqatshelwe ukuba ukusasazeka akuthethi ukupheliswa. Iimveliso ezikhawulezileyo ziphathwa nge-GlyOxal kumphezulu kwaye zisasazeke kumanzi abandayo, kodwa aziqali ukuba zinyibilikise ngoko nangoko. , Ke i-vickosity ayiveliswanga ngokukhawuleza emva kokusasazeka. Ngaphezulu inani elikhulu lonyango lwe-Glyoxal, ngokukhawuleza ukusasazeka, kodwa icotha i-vickosity, incinci inani le-Glysoxal, kunye ne-Gly.

I-07
Ngoku kukho i-selsulose eninzi eguqulweyo kunye ne-collet seluplose emarikeni, ke yintoni ukuguqulwa kunye nokudibanisa?

Olu hlobo lwe-seluplose zihlala zinepropathi enokuthi i-selsulose yoqobo ayinayo okanye iphucule ezinye iipropathi zayo, kufuneka iphucule indawo evulekileyo yokuphucula ukwakhiwa kwexabiso eliphantsi kweselsundi okanye i-sliulose
