sharraxaad gaaban:

MODCELLHaydroxypropyl Methyl Cellulose (HPMC), waaether-yada cellulose-ka aan ionic ahaynlaga soo saaray cellulose dabiici ah oo molecular sare leh (suuf la safeeyey) iyada oo loo marayo taxane falcelin kiimiko ah.

Waxay leeyihiin astaamo u eg biyo milmi kara,biyaha lagu hayohantida, nooca aan ionic ahayn, qiimaha PH ee deggan, dhaqdhaqaaqa dusha sare, dib u noqoshada xallinta jelling heerkul kala duwan,dhumuc weynaan, sameynta filim sameynta sibidhka, hantida saliidaynta, iska caabbinta caaryada iyo iwm.

Iyada oo leh dhammaan sifooyinkan, si ballaaran ayaa loogu isticmaalaa habka dhumucda, jelling, xasilinta joojinta, iyobiyaha lagu hayoduruufaha.

Su'aalaha Badiya La Weydiiyo

Waa maxay Hydroxypropyl Methyl Cellulose?

Hydroxypropyl methylcellulose (HPMC) waa cellulose ethers kuwaas oo lahaa kooxo hydroxyl ah oo ku jira silsiladda cellulose oo lagu beddelay kooxda methoxy ama hydroxypropyl.It waxaa lagu sameeyaa iyadoo si gaar ah loo nadiifiyo cellulose-ka cudbiga ah ee aadka u saafiga ah xaaladaha alkaline-ka. Sannadihii ugu dambeeyay, HPMC, oo ah isku-darka shaqada, ayaa inta badan door ka ciyaara.silaalinta biyaha iyo dhumucda warshadaha dhismaha waxaana si weyn loogu isticmaalaahoobiyeyaal drymix ah, sida dhejiska foornada, grouts, plastering, putty derbiga, is-le'egta, hoobiye dahaarka iyo iwm.

Waa maxay Heerkulka Jelka ee Hpmc?

Caadiyan, budada putty, dheellitirkaHPMCwaa ku filan qiyaastii 70,000 ilaa 80,000. Diiradda ugu weyn waxay saaran tahay waxqabadkeeda haysashada biyaha, halka saameynta dhumucduna ay tahay mid yar. Hoormoonka, shuruudaha loogu talagalayHPMCwaa ka sarreeyaan, dheellitirka biyahana waa inuu ahaadaa qiyaastii 150,000, taasoo hubin karta inay si fiican ugu shaqeyso hoobiyaha sibidhka. Dabcan, budada putty, ilaa iyo inta waxqabadka haynta biyaha ee HPMC uu wanaagsan yahay, xitaa haddii dheellitirku hooseeyo (70,000 ilaa 80,000), waa la aqbali karaa. Si kastaba ha ahaatee, hoobiyaha sibidhka, waxaa ugu habboon in la doorto HPMC oo leh dheellitir weyn (in ka badan 100,000), sababtoo ah saameynteeda haynta biyaha ayaa aad muhiim ugu ah xaaladdan.

Budada Putty-ga ee ka soo dhacaysa derbiga ma la xiriirtaa Hpmc?

Dhibaatada ka saarista budada putty waxay inta badan ku xiran tahay tayada kalsiyum hydroxide mana laha wax xiriir ah oo la leh HPMC. Haddii kaalshiyamka ku jira kalsiyum hydroxide uu hooseeyo ama saamiga CaO iyo Ca(OH)2 uusan habboonayn, waxay sababi kartaa in budada putty ay dhacdo. Marka laga hadlayo saameynta HPMC, waxay inta badan ka muuqataa waxqabadka haynta biyaha. Haddii waxqabadka haynta biyaha ee HPMC uu liito, waxay sidoo kale saameyn gaar ah ku yeelan kartaa baabi'inta budada putty.

Sidee Loo Doortaa Hpmc Ujeeddooyin Kala Duwan?

Shuruudaha loo baahan yahay isticmaalka budada putty waa kuwo aad u hooseeya. Dheecaanka 100,000 ayaa ku filan. Furaha ayaa ah in la helo sifooyin wanaagsan oo biyaha lagu hayo. Marka laga hadlayo hoobiyaha, shuruudaha waa kuwo aad u sarreeya waxaana loo baahan yahay daxal sare, badeecada 150,000-na waxay leedahay saameyn wanaagsan.
