Ka hopena o ka cellouse ether i ka pila

ʻO ka hoʻopiliʻana o ka Tement Heʻanoʻano o ka organic a iʻole ka adganic adminecture me ka cement e like me ka mea e hoʻopili ana i nā mea e hoʻopili ai i ka nui a me ka nui o ka nui a me ka nui o ka nui. hui pū. ʻO ka maʻamau, pono wale ia e hoʻohuiʻia me ka wai.

Ma ka wai paʻakai, ka wai i loko o ka mortar evaporates, ua hoʻopiliʻia ka cellulose eter i ka papa ma loko miner. ʻO ka'āpana o ka neʻeʻana i ka papa o ka papa o ka papa o ka myary

ʻO ke kiʻi kiʻi kiʻi o ka cellouse ether ma ka papa o ka payar he mana nui i ka hana o ka mory:
ʻO ka mea mua, he trit ited art

Mai kēia, ua hoʻomaopopoʻiaʻo ia ke kiʻiʻana i nā kiʻi paʻi kiʻi o ka eter i loaʻa i ka hopena nui o ka cellouse e loaʻa i ka manawa wehe. Keʻano o keʻano cellouse ether (hpmc,Hemc, Mc, etc.) a me ke kiʻekiʻe o ka eterification (pae o keʻano o ke kiʻina e pili ana i nā kiʻiʻoniʻoni.

2, ka ikaika
Ma kahi o ka hoʻopiʻiʻana i nā waiwai waiwai i weheweheʻia ma luna o ka palti, ka cellulouse ether i nā kinita o ka cement. ʻO kēia redartation ma muli o ka adsorption o nā mollue eter i nā mokuahi o nā myural i ka wai hydroxide. Ma ka huahana kemika,ʻaʻole pinepine ia i hoʻolahaʻia ma keʻano o ka mineral mua o ka clinker. Eia kekahi, ma muli o ka piʻiʻana o ka Viscosity o ka PROCSIty o ka PRECE RASPE, e hōʻemi ana i keʻano o nā mea hana hydration.

ʻO Viscosity kekahi mea nui'ē aʻe e hōʻike ana i nā waiwai o nā mea kanu o nā nalo cellouse. E like me ka mea i'ōleloʻia ma luna nei,ʻo ka viscosity nui e pili ana i ka nui o ka wai mālama pono a me ka hopena nui hoʻi i ka hana o ka hana hou. Eia naʻe, uaʻike nā haʻawina hoʻokolohua uaʻike keʻano o ka viscosity o keʻano o ka maʻi maʻi. He liʻiliʻi ka hopena o ka molecular ma ka hydration, a me kaʻokoʻa nui ma waena o nā kaupaona likeʻole he 10 min. No laila,ʻaʻole kahi paona molele
"ʻO ka noiʻana o ka cellouse eter i loko o nā huahana cement-i huiʻia e pili ana i nā huahana ʻO keʻano nui o keʻano nui no ka mhec,ʻo ke kiʻekiʻe kiʻekiʻe o ka midylation Eia kekahi, e like me nā mea i kohoʻia (e like me nā mea hana e like me ka hec)ʻoi aku ka nui o nā mea koho hydrophobic (e like me nā mea koho balota. ʻO ka hopena o ka resarding o nā celilouse e like me ka nui o nā'āpanaʻelua o keʻano a me ka nui o ka hui substitunts.
