Habka aqoonsiga fudud ee hydroxypropyl methylcellulose

Cellulose waxaa si weyn loogu isticmaalaa kiimikada batroolka, daawada, sameynta waraaqaha, qurxinta, agabka dhismaha, iwm. Waa wax lagu daro oo aad u badan, isticmaallo kala duwanna waxay leeyihiin shuruudo waxqabad oo kala duwan oo loogu talagalay alaabada cellulose.

Maqaalkani wuxuu inta badan soo bandhigayaa habka isticmaalka iyo aqoonsiga tayada ee HPMC (hydroxypropyl methylcellulose ether), oo ah nooc cellulose ah oo badanaa loo isticmaalo budada putty-ga caadiga ah.

HPMC waxay isticmaashaa cudbi la safeeyey oo ah walaxda ugu weyn ee ceeriin ah. Waxay leedahay waxqabad wanaagsan, qiimo sare iyo iska caabin alkali oo wanaagsan. Waxay ku habboon tahay matoorka caadiga ah ee biyaha u adkaysta iyo hoobiyaha polymer-ka ee laga sameeyay sibidhka, kalsiyum lime iyo agab kale oo alkaline ah oo xooggan. Kala duwanaanshaha dheddiggu waa 40,000-200000S.

Kuwa soo socda waa dhowr hab oo lagu tijaabinayo tayada hydroxypropyl methylcellulose oo ay soo koobtay Xiaobian. Kaalay oo wax ka baro Xiaobian~

1. Caddaannimo:

Dabcan, qodobka go'aaminaya tayada hydroxypropyl methylcellulose ma noqon karo oo keliya caddaan. Soo-saareyaasha qaar ayaa ku dari doona wakiilada caddeynta habka wax soo saarka, kiiskan, tayada lama qiimeyn karo, laakiin caddaanka hydroxypropyl methylcellulose ee tayada sare leh runtii waa mid wanaagsan.

2. Qurux:

Hydroxypropyl methylcellulose badanaa waxay leedahay jilicsanaan dhan 80 mesh, 100 mesh iyo 120 mesh. Jilicsanaanta walxaha aad bay u fiican tahay, milmida iyo haynta biyaha ayaa sidoo kale wanaagsan. Kani waa hydroxypropyl methylcellulose tayo sare leh.

3. Gudbinta iftiinka:

Ku rid hydroxypropyl methylcellulose biyaha oo ku mil biyo muddo ah si aad u hubiso isku-dhafka iyo hufnaanta. Ka dib marka jelka la sameeyo, hubi gudbinta iftiinka, sida uu u wanaagsan yahay gudbinta iftiinka, ayaa sii kordheysa maaddada aan milmi karin iyo daahirnimada.

4. Cufisjiidadka gaarka ah:

Cufisjiidadka gaarka ah ayaa sii weyn, maadaama cufisjiidadka gaarka ah ay sii culus yihiin, ayaa ka sii badanaya waxa ku jira hydroxypropyl methyl, ayaa sii wanaagsanaya haysashada biyaha.
