1. Codsiga ugu weyn ee cellulose ether hpmc?
HPMC waxaa si weyn loogu isticmaalaa hoobiyeynta dhismaha, rinjiga biyaha ku saleysan, rinjiga-ku-saleysan, isku-darka isku-darka, dhoobada, dawada, cuntada, waxyaabaha la isku qurxiyo, tubaakada, iyo warshadaha kale. Waxay u qaybsan tahay fasalka dhismaha, fasalka cuntada, fasalka dawooyinka, fasalka PVC warshadaha iyo heerka kiimikada maalinlaha ah.
2. Waa maxay kala-soocidda unugyada unugyada?
Cilmiga caadiga ah waa MC, HPMC, MHC, CMC, HEC, EC
Dhexdooda, HEC iyo CMC waxaa badanaa loo isticmaalaa jaakadaha biyaha ku saleysan;
CMC sidoo kale waxaa loo isticmaali karaa dhoobada, beeraha saliida, cuntada iyo meelaha kale;
EC waxaa badanaa loo isticmaalaa daawada, koollada qalin elektiroonigga ah iyo beeraha kale;
HPMC waxay u qaybsantahay faahfaahinno kala duwan waxaana loo isticmaalaa madaafiic, daawo, cunno, warshadaha PVC, alaabada kiimikada maalinlaha ah iyo warshadaha kale.
3. Waa maxay farqiga u dhexeeya HPMC iyo MHEC ee arji?
Sifooyinka labada nooc ee unugyada unugyada ayaa asal ahaan isku mid ah, laakiin xasilloonida heerkulka sare ee MHEC ayaa ka fiican, gaar ahaan xagaaga marka ay heerkulka derbiga ah ee MHEC uu ka fiican yahay xaaladaha heerkulka sare ee MHMC.
4. Sidee si fudud u xukuntaa tayada HPMC?
1) In kasta oo cadeynta aan la ogaan karin in HPMC ay fududahay in la isticmaalo, iyo haddii wakiilo caddaan ah lagu daro geedi socodka wax soo saarka, tayada ayaa saameyn ku yeelan doonta, laakiin inta badan waxyaabaha wanaagsan ay leeyihiin camal wanaagsan, oo laga saari karo muuqaalka kore.
2) Tartanka khafiifka ah The The The The The The The The The The The The The The The The The The The The The The The The The The The The The The The The The The The The The The The The The The The The The The The The The The The The The The The The The The The The The The The The The The The The Track.
Haddii aad rabto inaad si sax ah u xukumi karto tayada unugyada unugyada, habka ugu kalsoonida badan la isku halleyn karo waa in lagu isticmaalo qalabka xirfadleyda ah sheybaar xirfadeed si loo baaro. Tilmaamayaasha imtixaanka ugu weyn waxaa ka mid ah Viscosity, oo ah heerka haynta biyaha, iyo ashan ka kooban.
5. Sida loo cabbiro aragtida cellulose?
Muuqaalka caanka ah ee suuqa gudaha ee suuqa gudaha ayaa ah NDJ, laakiin suuqa caalamiga ah, soosaarayaal kaladuwan ayaa had iyo jeer u adeegsanaya hababka ogaanshaha Vecosity. Kuwa caanka ah waa brookfeld rv, hompler, waxaana sidoo kale jira xalal ogaanshaha oo kala duwan, oo loo qaybiyo 1% xalka iyo 2% xalka 2%. Muuqaalada kaladuwan iyo habab ogaal-ka-ogaal ah oo kaladuwan ayaa badanaa keena in isbedel dhowr jeer ama xitaa laba iyo toban jeer oo ah natiijooyinka viscosity.
6. Waa maxay farqiga u dhexeeya nooca degdega ah ee HPMC iyo nooca kulul ee kulul?
Alaabada degdegga ah ee HPMC waxay tixraacdaa alaabada si dhaqso leh u kala firdhiya biyaha qabow, laakiin waa in la ogaadaa in kala-baxa uusan macnaheedu ahayn kala-baxa. Alaabada degdegga ah waxaa lagu daaweeyaa geltiomal dusha sare waxaana lagu kala firdhiyaa biyo qabow, laakiin uma bilaabaan inay si dhakhso leh u baabi'iyaan. Marka, markaa codku ma dhaliyo isla markiiba kala firidhsan kadib. Inta badan tirada daaweyn dusha sare ee geltiomal, si dhakhso leh u kala firidhsan, laakiin tartiib tartiib tartiib tartiib tartiib, tirada yar ee gellical, iyo dhanka kale.
7. Qeybta unugyada ee isku-darka iyo wax laga beddelay
Hadda waxaa jira waxyaabo badan oo ka yar oo wax laga beddelay oo ka buuxaan suuqa suuqa, markaa waa maxay wax ka badalida iyo xarunta?
Noocan oo kale ah ee cellulose wuxuu badanaa leeyahay guryo uu unugyada asalka ahi uusan lahayn ama kor u qaadin qaar ka mid ah dhismaheeda, sida: waqtiyo la-dagaallanka oo kordhay, in la dhinto si loo yareeyo si loo yareeyo kharashaadka loo yaqaan 'cellulose'. Macmiil ahaan, iskuday inaad kala soocdo oo aan lagu khiyaanayn. Waxaa ugu wanaagsan in la doorto wax soo saar la isku halleyn karo oo ka socda noocyada waaweyn iyo warshadaha waaweyn.
