Mphamvu Yowonjezera Njira ya Hydroxyethyl Cellulose pa Properties of Latex

Pakalipano, palibe lipoti la zotsatira za njira yowonjezera ya hydroxyethyl cellulose pa dongosolo la utoto la latex. Kupyolera mu kafukufuku, apeza kuti kuwonjezera kwa hydroxyethyl cellulose mu latex penti system ndi yosiyana, ndipo ntchito ya utoto wokonzeka wa latex ndi wosiyana kwambiri. Pankhani ya kuwonjezera komweko, njira yowonjezeramo ndi yosiyana, ndipo kukhuthala kwa utoto wokonzedwa wa latex ndi wosiyana. Kuonjezera apo, njira yowonjezera ya hydroxyethyl cellulose imakhalanso ndi zotsatira zoonekeratu pakusungirako kukhazikika kwa utoto wa latex.

Njira yowonjezeramo hydroxyethyl cellulose mu utoto wa latex imatsimikizira kupezeka kwake mu utoto, ndipo chikhalidwe cha kubalalitsidwa ndi chimodzi mwa mafungulo ake kukhuthala kwake. Kupyolera mu kafukufuku, anapeza kuti hydroxyethyl mapadi anawonjezera mu siteji kubalalitsidwa anakonza mwadongosolo pansi zochita za kukameta ubweya mkulu, ndipo n'zosavuta Wopanda wina ndi mzake, ndi akuthwana ndi zopiringizana okhudza malo maukonde dongosolo awonongedwa, potero kuchepetsa thickening dzuwa. Phala la HEC lomwe linawonjezeredwa mu sitepe yotsitsa lili ndi kuwonongeka kochepa kwambiri kwa dongosolo la danga la danga panthawi yochepetsera mofulumira, ndipo zotsatira zake zowonjezera zimawonekera bwino, ndipo mawonekedwe a maukondewa ndi opindulitsa kwambiri kuti atsimikizire kukhazikika kosungirako utoto wa latex. Mwachidule, kuwonjezeredwa kwa hydroxyethyl cellulose HEC mu gawo lotsitsa la utoto wa latex kumathandizira kwambiri pakukhuthala kwake komanso kukhazikika kosungirako.

Ma cellullosic thickeners nthawi zonse akhala chimodzi mwazowonjezera zofunikira kwambiri za utoto wa latex, zomwe hydroxyethyl cellulose (HEC) ndizomwe zimagwiritsidwa ntchito kwambiri. Malinga ndi malipoti ambiri a mabuku, zokometsera za cellulose zili ndi izi: kukhuthala kwakukulu, kuyanjana kwabwino, kukhazikika kosungirako, kukana bwino kwa sag, ndi zina zotero. Njira yowonjezera ya hydroxyethyl cellulose popanga utoto wa latex ndi yosinthika, ndipo njira zowonjezera zowonjezera ndi izi:

01. Onjezani pa pulping kuonjezera mamasukidwe akayendedwe a slurry, motero kumathandiza kupititsa patsogolo kubalalitsidwa Mwachangu;

02. Konzani phala la viscous ndikuwonjezera pamene mukusakaniza utoto kuti mukwaniritse cholinga cha thickening.
