Habka aqoonsiga fudud ee hydroxypropyl methylrcellesulose

Cellulose waxaa si ballaaran loogu isticmaalaa petrochemical, daawo, is-qurxinta, waxyaabaha dhismaha, qalabka dhismaha, iwm.

Qodobkaani wuxuu inta badan soo bandhigayaa habka loo adeegsado iyo habka aqoonsiga tayada leh ee HPMC (hydroxypropyl methylrellalose ether), noocyo kala duwan oo unug ah oo loo adeegsado budada isugeynta caadiga ah.

HPMC waxay isticmaashaa suufka la soo dhigay inuu yahay sheyga ugu weyn ee ceeriin. Waxay leedahay waxqabad wanaagsan, qiimo aad u sareysa iyo iska caabbinta alkali wanaagsan. Waxay ku habboon tahay hoobiyeyaasha biyaha u adkaysta biyaha iyo hoolka polymer ee ka samaysan sibidhka, kalsiyaha nuuradda liinta iyo agabyada kale ee alkaline ee xoogga leh. Tartanka Viscosity waa 40,000-200000s.

Kuwa soo socdaa waa dhowr habab oo lagu tijaabiyo tayada hydroxypropyl methylcelrellase lagu soo koobay Xiaobian adiga. Kaalay oo wax ka barta Xiabian ~

1. Cunnerinimo:

Dabcan, qodobka muhiimka ah ee go'aaminta tayada hydroxypropyl methylcelrellase ma noqon karto mid cad. Qaar ka mid ah soosaarayaasha ayaa ku dari doona wakiilo cadaalad ah oo ku saabsan nidaamka wax soo saarka, kiiskan, tayada aan la xukumi karin, laakiin cadaankan lama xukumi karo, laakiin cadaanka ah ee ku jira hydroxypropyl methylcellosuse runtii waa wanaagsan tahay.

2. Feejignaan:

Hydroxypropylykylkellellalose badanaa waxay leedahay dhagaysi boqolkiiba 80 mesh, 100 mesh iyo 120 mesh. Finalka walxaha waa mid aad u fiican, iyo fadhiishadda iyo haynta biyaha sidoo kale waa wanaagsan yihiin. Tani waa tayo tayo sare leh oo tayo sare leh methylcelrelose.

3. TILMAAMAHA GUUD:

Ku rid hydroxypropyl methylrcellulose biyo oo ku dhex milma biyo si aad u hubiso viscosity iyo daahfurnaanta. Ka dib markii Gelidda la sameeyo, hubi in iftiinka loo gudbiyo, sida ugu fiican ee loo yaqaan 'transminge'.

4. Xirfad gaar ah:

Cudurrada weyn ee culeyska gaarka ah, waxa ugu fiican, maxaa yeelay waxa uu culus yahay culayska gaarka ah, waxa ku jira waxa ku jira ee ku jira biyo-ku-taaloyinka hyroxypropyly methyl ee methyl, haynta biyaha.
