1. Cilmiga dabiiciga ah ee dabiiciga ah
Qalabka aasaasiga ee aasaasiga ah eeHPMCWaa unugyada dabiiciga ah ee dabiiciga ah, oo inta badan laga soo saaro alwaax alwaax ama suuf cudbi ah. Fikeryaalka dhirta dabiiciga ah waxay ka kooban yihiin qadar aad u badan oo ah unugyada dhismayaasha gulukooska ee gulukoosta waxayna aasaas u yihiin soo saarista HPMC. Burburka sare ee suufka ah ee suufka ah ayaa badanaa loo isticmaalaa soosaarka HPMC tayo sare leh sababtuna tahay buruqsanaanta uumiga yar yahay.
2. Sodium Hydroxide (Nahoh)
Sodium Hydroxide (NaOh) ayaa looga baahan yahay ka-hortagga iyo alantalization ee cellulose. Hawlaha ugu waaweyn waxaa ka mid ah:
Barar unugyada unugyada unugyada iyo dhaqdhaqaaqa dareenka sii kordhaya;
Burburinta aagga Crystalline ee cellulose si ay u fududaato in lagu maleeyo falcelinta qadhaadh;
Kor u qaadista methylation-ka ku xiga iyo falcelinta hydroxypropylation.
3. Methyl chloride (ch₃l)
Methyl chloride (methyl chloride) waa fure fure u ah falcelinta methlation ee wax soo saarka Kimacell®HpMC. Waxay ka falcelisay unugyada unugyada ah ee loo yaqaan 'clulolese' oo lagu beddelo qaar ka mid ah hydroxyl kooxaha hydroxyl (-h) oo leh kooxo cothoxy ah (-och₃) si loo sameeyoMetyl bylulose (MC), markaa waxay hagaajinaysaa xannuunka iyo astaamaha jidhka iyo kiimikada ee unugyada cellulose.
4. Propylene Oxide (C₃h₆o)
Propyleneneneneneen waxaa loo isticmaalaa falcelinta hydroxypropylation, kaas oo soo bandhigi kara hydroxypropyl (-ch₂chohchch₃) kooxaha ku jira silsiladda unugyada unugyada maskaxda. Hordhac Hydroxypropyl ayaa:
Si dheeraad ah u wanaajiso jilitaanka biyaha ee HPMC;
Hagaajinta mowqifka iyo astaamaha rheolologial ee xalka;
Wanaajinta xasilloonida heerkulka kala duwan.
5. Xalka (biyaha ama dareeraha dabiiciga ah)
Biyaha ama dareeraha dabiiciga ah (sida menanpropanol, methanol, iwm.) Waxaa loo isticmaalaa sida fal-celinta fal-celinta ee geedi socodka wax soo saarka si looga caawiyo isku-darka isku-darka agabyada iyo xakamaynta falcelinta. Intaas waxaa sii dheer, qaar ka mid ah dareeraha qaarkood ayaa loo isticmaalaa in lagu tirtiro wax soo saarka aan laga soo saarin ee ku jira nidaamka ku xiga iyo habka wax lagu dhaqo si loo hubiyo daahirka sheyga.
6. Acidic-ka Acidic ama Alkaline
Si loo saadaaliyo xaaladaha fal-celinta iyo hagaajinta hufnaanta qaraabada, aashitada ama qalabka wax lagu dhejiyo sida sodium bicarbonate (nahcuric acid (h₂so₄), in la hagaajiyo nidaamka wax soo saarka si jawaab-celinta loo sii wado xaaladaha wanaagsan.
7. Qalabka kale ee kaaliyaha ah
Xoogaanada qaar, kuwa xakameeya ama waxyaabaha kale ee kiimikada ah ayaa loo isticmaali karaa habka wax soo saarka si loo wanaajiyo tayada HPMC, kor u qaadista xasilloonida, oo ay xakameyso guryaha jireed iyo kiimikada.
Kimacel®HpMC waxaa badanaa soo saaray alantalization, methylation iyo hydroxypropylation ee unugyada dabiiciga ah.Alaabtiisa ugu weyn ee ceyriinka ah waxaa ka mid ah:
Cell-ka dabiiciga ah (badiyaa laga soo qaatay alwaax alwaax ah ama suufka la safeeyey)
Sodium Hydroxide (NaOh) (oo loogu talagalay alantalization)
Metyl chloride (ch₃l) (ee methylation)
Propylene oxide (c₃h₆o) (ee hydroxypropylation)
Biyo ama dareeraha dabiiciga ah (falcelinta iyo maydhista)
Soo-saareyaasha iyo xasilinta (si loogu fiicnaado falcelinta)
HPMC waxaa si weyn loogu isticmaalaa warshado badan sida daawada, dhismaha, cuntada, iyo jaakadaha, iyo culeyska biyaha ee wanaagsan, awoodda hagaajinta sawirka iyo daadadka.
