Habka aqoonsiga fudud ee hydroxypropyl methylcellulose

Cellulose waxaa si weyn loogu isticmaalaa petrochemical, daawooyinka, waraaqaha, isku qurxiyo, qalabka dhismaha, iwm

Maqaalkani wuxuu inta badan soo bandhigayaa isticmaalka iyo habka aqoonsiga tayada ee HPMC (hydroxypropyl methylcellulose ether), noocyo cellulose ah oo caadi ahaan loo isticmaalo budada caadiga ah.

HPMC waxay isticmaashaa suufka la safeeyey sida alaabta ceeriin ee ugu weyn.Waxay leedahay waxqabad wanaagsan, qiimo sare leh iyo iska caabin alkali oo wanaagsan.Waxay ku habboon tahay maaddooyinka caadiga ah ee biyaha u adkaysta iyo dhoobada polymer ee laga sameeyay sibidhka, calcium lime iyo walxaha kale ee alkaline ee xooggan.Qiyaasta viscosity waa 40,000-200000S.

Kuwa soo socda waa dhowr habab oo lagu tijaabiyo tayada hydroxypropyl methylcellulose oo ay Xiaobian kuu soo koobtay adiga.Kaalay oo la baro Xiaobian ~

1. Caddaan:

Dabcan, qodobka ugu muhiimsan ee lagu go'aaminayo tayada hydroxypropyl methylcellulose ma noqon karto caddaan kaliya.Qaar ka mid ah wax-soo-saareyaasha ayaa ku dari doona walxaha cadcad ee habka wax soo saarka, kiiskan, tayada lama xukumi karo, laakiin caddaanka tayada sare leh ee hydroxypropyl methylcellulose waa mid aad u fiican.

2. Wanaag

Hydroxypropyl methylcellulose caadi ahaan waxay leedahay ganaax ah 80 mesh, 100 mesh iyo 120 mesh.Wanaagsanaanta qaybaha waa mid aad u fiican, iyo milanka iyo haynta biyaha ayaa sidoo kale wanaagsan.Tani waa hydroxypropyl methylcellulose oo tayo sare leh.

3. Gudbinta fudud:

Ku rid hydroxypropyl methylcellulose biyo oo ku mil biyaha muddo wakhti ah si loo hubiyo viscosity iyo hufnaanta.Ka dib marka jelku sameeyo, hubi gudbintiisa iftiinka, sida wanaagsan ee gudbinta iftiinka, sare u kaca maadada aan milmi karin iyo nadiifnimada.

4. Cuf-jiid gaar ah:

Weynaanta cuf-jiidadka gaarka ah, ayaa ka sii wanaagsan, sababtoo ah culeyska culeyska gaarka ah, ayaa sare u kaca maadada hydroxypropyl methyl ee ku jirta, way ka sii fiicnaanaysaa haynta biyaha.
