Kutha kwa msika kumathandizira

Zowonjezera za mankhwala ndizosangalatsa komanso zowonjezera zomwe zimagwiritsidwa ntchito popanga mankhwala ndi malangizo, ndipo ndi gawo lofunikira pakukonzekera kwa mankhwala. Monga chilengedwe cha polymer odetsedwa, cellulose ethergradgle, osakhala poizoni, komanso otsika mtengo, monga cellolithyl cellolithyl cellose ali ndi mtengo wofunikira mu Zosangalatsa za mankhwala. Pakadali pano, zopangidwa ndi ma etherpulic ethermic ma cellulose zimagwiritsidwa ntchito makamaka m'minda yapakati ndi yotsika kwambiri ya mafakitale, ndipo mtengo wowonjezereka siwokwezeka. Makampaniwa amafunikira kusintha komanso kukweza kusintha kwa zinthu zomaliza.

Zofunikira za mankhwala opangira zimatenga gawo lofunikira pakupanga ndi kupanga. Mwachitsanzo, mumasulidwa-kutukwana, zida zomasulira monga ma cellulose zimagwiritsidwa ntchito ngati mankhwala omasulira, matepi okhazikika, amasulidwa mafilimu omasulidwa, ndikusintha mankhwala osokoneza bongo. Kukonzekera ndi kukonzekera kwamadzi kokhazikika kwagwiritsidwa ntchito kwambiri. M'dongosolo lino, ma polima monga etheluse ethelose nthawi zambiri amagwiritsidwa ntchito ngati mankhwala onyamula mankhwala omwe angayang'anire kumasulidwa kwa mankhwala osokoneza bongo m'thupi la munthu.

Malinga ndi ziwerengero kuchokera ku dipatimenti yophunzira za ZHyan, pali mitundu pafupifupi 500 yomwe yatchulidwa mu dziko langa, koma poyerekeza ndi United States (mitundu yoposa 3,000), mitundu ikuluikulu idakalipo pang'ono. Kutha kwa msika ndi kwakukulu. Zimamveka kuti zothandizira khumi ndi zoyambira pamsika wa dziko la gelatin ndi makapisozi, owuma, ma pvmc, hydrox, ma celctose.
