1. Nā etera cellulose (MC, HPMC, HEC)
Hoʻohana maʻamau ʻia ʻo MC, HPMC, a me HEC i ke kūkulu ʻana i ka putty, pena, mortar a me nā huahana ʻē aʻe, ka mea nui no ka mālama ʻana i ka wai a me ka lubrication. he maikai.
Ka nānā a me ka ʻike ʻana:
E kaupaona i 3 grams o MC a i ʻole HPMC a i ʻole HEC, e hoʻokomo i loko o 300 ml o ka wai a hoʻoulu a hiki i ka hoʻoheheʻe ʻia ʻana i loko o kahi hopena, e hoʻokomo i kāna ʻano wai i loko o kahi hue wai mineral maʻemaʻe, ʻikea, e uhi a hoʻopaʻa i ka pāpale, a hoʻokomo iā ia i loko E nānā i nā loli o ka hoʻonā kelu i ke kaiapuni o -38°C. Inā maopopo a maopopo ka hoʻonā wai, me ka viscosity kiʻekiʻe a me ka wai maikaʻi, ʻo ia ka manaʻo o ka huahana. E hoʻomau i ka nānā ʻana ma mua o 12 mau mahina, a ʻaʻole i hoʻololi ʻia, e hōʻike ana he kūpaʻa maikaʻi ka huahana a hiki ke hoʻohana me ka hilinaʻi; inā ʻike ʻia ka hoʻololi ʻana i ka waihoʻoluʻu o ka wai, ʻoi aku ka lahilahi, lilo i ʻāhuehue, loaʻa ka ʻala rancid, loaʻa i ka lepo, hoʻonui i ka ʻōmole, a hoʻemi i ke kino o ka ʻōmole Hōʻike ʻia ʻaʻole maikaʻi ka maikaʻi o ka huahana. Inā hoʻohana ʻia i ka hana ʻana i nā huahana, e alakaʻi ia i ka maikaʻi o ka huahana paʻa ʻole.
2. CMCI, CMCS
ʻO ka viscosity o CMCI a me CMCS aia ma waena o 4 a me 8000, a ua hoʻohana nui ʻia lākou i ka pae ʻana o ka paia a me nā mea plastering e like me ka putty pā hale maʻamau a me ka plaster plaster no ka mālama ʻana i ka wai a me ka lubrication.
Ka nānā a me ka ʻike ʻana:
E kaupaona i 3 grams o ka CMCI a i ʻole CMCS, e hoʻokomo i loko o 300 ml o ka wai a hoʻoulu a hiki i ka hoʻoheheʻe ʻia ʻana i loko o kahi hopena, e waiho i kāna wai wai i loko o kahi hue wai mineral maʻemaʻe, ʻikea, ʻole, uhi a hoʻopaʻa i ka pāpale, a hoʻokomo i loko E nānā i ka hoʻololi ʻana o kāna ʻano wai i loko o ke kaiapuni o ℃, inā he wai ka wai, ʻo ia ka mānoanoa o ka wai, ʻo ia ka mānoanoa. He pahū ka hopena a he sediment, ʻo ia hoʻi, aia i loko o ka huahana ka pauka ʻele, a ua moekolohe ka huahana. . E hoʻomau i ka nānā ʻana ma mua o 6 mau mahina, a hiki ke hoʻololi ʻole ʻia, e hōʻike ana he kūpaʻa maikaʻi ka huahana a hiki ke hoʻohana ʻia me ka hilinaʻi; inā ʻaʻole hiki ke mālama ʻia, ʻike ʻia e loli mālie ke kala, ʻoi aku ka lahilahi o ka hopena, lilo i ao, aia ka sediment, ʻala rancid, a pehu ka hue, e hōʻike ana ʻaʻole paʻa ka huahana, inā hoʻohana ʻia i ka huahana, e hoʻopilikia i ka maikaʻi o ka huahana.
