Kodi cellulose ndi chifukwa chiyani amagwiritsidwa ntchito?

Te cellulose ndi ma poity osungunuka madzi opangidwa kuchokera ku cellulose, gawo lalikulu la zomera. Pali mitundu ingapo ya cellulose etrase, iliyonse yokhala ndi malo apadera omwe amawapangitsa kuti azigwiritsa ntchito mitundu yosiyanasiyana.

Makina opanga ma cellulose edease amagwiritsidwa ntchito pa chilichonse kuchokera ku mankhwala ndi zodzoladzola pomanga komanso kupanga mameseji. Kuphatikiza apo, amagwiritsidwa ntchito ngati zowonjezera za chakudya ndi owaza mu utoto ndi zokutira.

Mitundu ya cellulose et

Mitundu itatu yodziwika bwino ya cellulose ndi hydroxypropylmethylcelulose (hpmc), methylhyhylhydroxycellulose (Mithec).

Chifukwa cha kusiyanasiyana, HPMC ndiye mtundu wa ether wogwiritsidwa ntchito kwambiri wa cellulose. Imapezeka m'makalasi osiyanasiyana okhala ndi zolemera zosiyanasiyana, madigirineti ndi mawonekedwe. HPMC itha kugwiritsidwa ntchito pamavuto onse a acidic ndi alkaline, ndikupanga kukhala yabwino kugwiritsa ntchito mitundu ingapo.

Mic ndiwofanana ndi hpmc koma ali ndi zotsika za hydroxypyl. Poyerekeza ndi HPMC, kutentha kwa kutentha kwa mic nthawi zambiri kumakhala kokwera kuposa 80 ° C, kutengera zomwe gulu limapanga komanso kupanga njira. Micy nthawi zambiri amagwiritsidwa ntchito ngati Thicner, Bander, emulsion khrisifa kapena kanema wakale.

Cellulose eds ali ndi ntchito zambiri chifukwa chazomwe zili m'malo mwapadera. Magwiridwe ena odziwika bwino a cellulose akuphatikizira:

Otsatsa: Cellulose eder amatha kugwiritsidwa ntchito ngati makulidwe a mafuta opaka mafuta, zomata, mankhwala a mafuta, chakudya, zodzola, ndi mankhwala odzola.

Banders: Cellulose eder amatha kugwiritsidwa ntchito ngati matchire m'mapiritsi kapena magalamu. Amakhala osokoneza bongo a ufa mukakhalabe woyenda bwino.

Otsutsa a Emulsion: Chuma Izi zimawapangitsa kukhala abwino kugwiritsa ntchito ku emulsion poliseche monga zomata za latex utoto kapena zomatira.

Mitundu ya film: cellulose yokhazikika imatha kugwiritsidwa ntchito popanga mafilimu kapena zokutira pamalo. Nthawi zambiri amagwiritsidwa ntchito popanga zomanga monga matayala kapena ma Wallpaper. Makanema opangidwa kuchokera ku cellulose eders nthawi zambiri amawonekera komanso kusinthasintha, ndikukana chinyontho.
