Mankhwala a HPMC

Mankhwala a HPMCHydroxypropyl methylcellulose ndi yoyera kapena yoyera ngati mkaka, yopanda fungo, yopanda kukoma, ufa kapena granule wa ulusi, kuchepetsa thupi mukauma sikupitirira 10%, kumasungunuka m'madzi ozizira koma osati m'madzi otentha, pang'onopang'ono m'madzi otentha. Kutupa, kufalikira, ndikupanga yankho la colloidal lokhuthala, lomwe limakhala yankho likazizira, ndipo limakhala gel likatenthedwa. HPMC sisungunuka mu ethanol, chloroform ndi ether. Imasungunuka mu solvent yosakanikirana ya methanol ndi methyl chloride. Imasungunukanso mu solvent yosakanikirana ya acetone, methyl chloride ndi isopropanol ndi zina zosungunulira zachilengedwe. Yankho lake lamadzi limatha kupirira mchere (yankho lake la colloidal siliwonongedwa ndi mchere), ndipo pH ya yankho lamadzi la 1% ndi 6-8. Fomula ya molekyulu ya HPMC ndi C8H15O8-(C10H18O6) -C815O, ndipo kulemera kwa molekyulu ndi pafupifupi 86,000.

Kufotokozera kwa Mankhwala

Kalasi ya Zamalonda:

Kugwiritsa ntchito

Makhalidwe ndi Ubwino:

HPMC imasungunuka bwino kwambiri m'madzi ozizira. Imatha kusungunuka kukhala yankho lowonekera bwino ndikusakaniza pang'ono m'madzi ozizira. M'malo mwake, siisungunuka kwenikweni m'madzi otentha opitilira 60.℃ndipo imatha kutupa kokha. Ndi ether yopanda ionic cellulose. Yankho lake silikhala ndi mphamvu ya ionic, siligwirizana ndi mchere wachitsulo kapena mankhwala a ionic organic, ndipo silichita ndi zinthu zina zopangira panthawi yokonzekera; lili ndi anti-sensitivity yamphamvu, ndipo pamene kuchuluka kwa kusintha kwa kapangidwe ka mamolekyu kumawonjezeka, limalimbana kwambiri ndi ziwengo komanso limakhazikika; komanso siligwira ntchito bwino. Monga chowonjezera cha mankhwala, silimasinthidwa kapena kuyamwa. Chifukwa chake, silipereka kutentha m'mankhwala ndi zakudya. Ndi lotsika ma calories, lopanda mchere, komanso lopanda mchere kwa odwala matenda ashuga. Mankhwala ndi zakudya zomwe zimayambitsa ziwengo zimakhala ndi ntchito yapadera; ndi lokhazikika pang'ono ku ma acid ndi alkalis, koma ngati PH yapitirira 2 ~ 11 ndipo yakhudzidwa ndi kutentha kwakukulu kapena ili ndi nthawi yayitali yosungira, kukhuthala kwake kudzachepa; yankho lake lamadzi lingapereke ntchito ya pamwamba, kusonyeza kupsinjika pang'ono pamwamba ndi ma values ​​​​ovuta pakati pa nkhope; lili ndi emulsification yogwira ntchito m'magawo awiri, lingagwiritsidwe ntchito ngati stabilizer yothandiza komanso colloid yoteteza; Madzi ake ali ndi mphamvu zabwino kwambiri zopangira filimu, ndipo ndi piritsi ndi piritsi. Chophimba cha filimu chomwe chimapangidwa ndi iyo chili ndi ubwino wosakhala ndi utoto komanso kulimba. Kuwonjezera glycerin kungathandizenso kuti ipangike bwino.

Kulongedza

TKulongedza kwachizolowezi ndi 25kg/Ulusing'oma 

20'FCL: matani 9 okhala ndi mapaleti; matani 10 osapakidwa mapaleti.

40'FCL:18tani yokhala ndi pallet;20tani yosaphwanyidwa.

Malo Osungira:

Sungani pamalo ozizira, ouma osapitirira 30°C ndipo mutetezedwe ku chinyezi ndi kukanikiza, popeza katunduyo ndi thermoplastic, nthawi yosungira siyenera kupitirira miyezi 36.

Zolemba zachitetezo:

Deta yomwe ili pamwambapa ikugwirizana ndi zomwe tikudziwa, koma musalole makasitomala kuti aziyang'ana zonse mosamala nthawi yomweyo akalandira. Kuti mupewe mitundu yosiyanasiyana ya mankhwala ndi zinthu zosiyanasiyana zopangira, chonde yesani zambiri musanagwiritse ntchito.
