Heerka dhoobada HPMC
dhoobadadarajada HPMC Hydroxypropyl Methylcellulose waa eter cellulose aan-ionic ahayn oo laga sameeyay maadada polymer-ka dabiiciga ah (suuf) cellulose iyada oo loo marayo taxane kiimiko ah. Waa budo cad oo ku barara xal kolloidal ah oo cad ama waxoogaa turbid ah oo biyo qabow ah. Waxay leedahay sifooyinka dhumuc, isku-xidhka, kala firdhinta, emulsification, samaynta filimka, joojinta, adsorption, gelation, dhaqdhaqaaqa dusha sare, xajinta qoyaanka iyo kolloid ilaalinta.
Theisticmaalof hydroxypropyl methylcellulose HPMC ee soo saarista tignoolajiyada dhoobada waxay kordhisaa caagagga iyo xoogga embriyaha ama dhaldhalaalka, waxay si weyn u kordhisaa saamaynta saliidda, waxayna faa'iido u leedahay shiididda kubbadda. Intaa waxaa dheer, ka joojinta iyo xasilloonida ayaa si weyn loo wanaajiyey, iyo foornada ayaa fiican. , Codku waa jilicsan yahay. Mashiinka glaze-ku waa siman yahay, wuxuu leeyahay gudbin iftiin wanaagsan, iska caabin shil, wuxuuna leeyahay heer gaar ah oo xoog farsamo ah. HPMC waxay leedahay sifooyin jel kuleyl ah waxaana si weyn loogu isticmaalaa xire ahaan soo saarista dhoobada.

Astaamaha
Ku daridadarajada dhoobadaAlaabta dhoobada ah ee HPMC ilaa malabka waxay gaari kartaa:
1. Shaqeynta taayirada caaryada alaabta dhoobada malabka
2. Xoog cagaaran oo ka fiican alaabta dhoobada malabka
3. Waxqabadka sifaynta ka wanaagsan, kaas oo ku habboon qaabaynta extrusion
4. Dushu waa wareegsan oo jilicsan
5. Alaabta dhoobada malabka ayaa leh qaab-dhismeed gudaha ah oo aad u cufan ka dib gubasho
ceramics-ka Malabka ayaa si weyn loogu isticmaalaa soo saarista tamarta, nadiifinta iyo nadiifinta, iyo daaweynta gaasta qiiqa baabuurta. Horumarka tignoolajiyada, tignoolajiyada dhoobada malabka oo aad iyo aad u dhuuban ayaa la isticmaalaa. Hydroxypropyl methyl cellulose wuxuu door muhiim ah ka ciyaaraa soo saarista dhoobada malabka ee dhuuban, wuxuuna door muuqda ku leeyahay ilaalinta qaabka jidhka cagaarka ah.
Baakadaha
Tbaakadaha caadiga ah waa 25kg/bac
20'FCL: 12 tan oo baalaysan; 13.5 tan aan baalaysan.
40'FCL:24tan oo leh palletized;28tan aan palette lahayn.
Kaydinta:
Ku kaydi meel qabow oo qallalan oo ka hooseysa 30 ° C oo laga ilaaliyo qoyaanka iyo cadaadiska, maadaama alaabtu tahay heerkulbeeg, wakhtiga kaydinta waa inuusan ka badnaan 36 bilood.
Qoraallada badbaadada:
Xogta kor ku xusan waxay waafaqsan tahay aqoontayada, laakiin ha ka nadiifin macaamiisha si taxadar leh u hubiya dhammaan isla markiiba marka la helo. Si aad isaga ilaaliso diyaarinta kala duwan iyo alaabta ceeriin ee kala duwan, fadlan samee baaritaan dheeraad ah ka hor intaadan isticmaalin.
