EHEC ndi MEHEC

EHEC (ethyl hydroxyethyl mapadi) ndi MEHEC (methyl ethyl hydroxyethyl mapadi) ndi mitundu iwiri yofunikira ya ma cellulose ethers omwe amagwiritsidwa ntchito m'mafakitale osiyanasiyana, kuphatikiza utoto ndi zokutira makampani. Tiyeni tifufuze mozama mu chilichonse:

1. EHEC (Ethyl Hydroxyethyl Cellulose):
   • Kapangidwe ka Mankhwala: EHEC imachokera ku mapadi poyambitsa magulu onse a ethyl ndi hydroxyethyl pamsana wa cellulose.
   • Katundu ndi Ntchito:
     • EHEC ndi sungunuka m'madzi ndi kupanga mandala, viscous zothetsera.
     • Imagwira ntchito ngati chowonjezera komanso chosinthira ma rheology mu utoto ndi zokutira zokhala ndi madzi, kuwongolera kukhuthala ndikuwongolera magwiridwe antchito.
     • EHEC amapereka pseudoplastic kapena kukameta ubweya-kupatulira khalidwe kupenta formulations, kutanthauza mamasukidwe akayendedwe amachepetsa ndi kuwonjezeka kumeta ubweya mlingo, kutsogolera ntchito mosavuta ndi brushability yosalala.
   • Mapulogalamu:
     • EHEC chimagwiritsidwa ntchito mkati ndi kunja utoto, zoyambira, ndi zokutira kukwaniritsa kugwirizana ankafuna, otaya, ndi kusanja katundu.
     • Ndiwothandiza makamaka pamapangidwe pomwe kukhuthala kwakukulu pamitengo yotsika yometa ubweya kumafunikira pakukana kwa sag komanso kupanga filimu bwino.
2. MEHEC (Methyl Ethyl Hydroxyethyl Cellulose):
   • Kapangidwe ka Mankhwala: MEHEC ndi efa yosinthidwa ya cellulose yokhala ndi methyl, ethyl, ndi hydroxyethyl m'malo mwa cellulose.
   • Katundu ndi Ntchito:
     • MEHEC amawonetsa kusungunuka kofanana ndi katundu wa rheological ku EHEC koma ndi zosiyana pakuchita.
     • Imakhala ndi mphamvu zosungirako bwino zamadzi poyerekeza ndi EHEC, ndikupangitsa kuti ikhale yoyenera pamipangidwe pomwe nthawi yotseguka yotalikirapo kapena kukula kwamtundu kumafuna.
     • MEHEC imapereka mphamvu zowonjezera zowonjezera komanso kukhazikika pamitundu yosiyanasiyana ya pH ndi kutentha.
   • Mapulogalamu:
     • MEHEC imapeza ntchito mu utoto wamadzi, zokutira, ndi zida zomangira komwe kumafunikira kusungika bwino kwa madzi, kukhuthala, ndi kuwongolera kwamadzi.
     • Nthawi zambiri amagwiritsidwa ntchito popanga utoto wokongoletsera, zokutira, ndi kumaliza kwapadera komwe nthawi yotalikirapo yogwira ntchito komanso kuyenda bwino ndikofunikira.

Onse EHEC ndi MEHEC ndi zosunthika mapadi etha amene amapereka formulators kusinthasintha kukwaniritsa ankafuna makhalidwe mu utoto ndi zokutira madzi. Kugwirizana kwawo ndi zina zowonjezera, zosavuta zophatikizika muzopanga, komanso kuthekera kopititsa patsogolo zinthu zofunika kwambiri monga kuwongolera ma viscosity, kusunga madzi, komanso kugwiritsa ntchito zinthu zomwe zimawapangitsa kukhala zigawo zamtengo wapatali popanga zokutira zapamwamba kwambiri.
