Whakarāpopototanga:Mā roto i ngā whakamātautau orthogonal, ka tūhuratia e tēnei pepa te awe me te ture o te cellulose ether ki ngā āhuatanga matua o ngā piri taera. He hiranga tohutoro ngā āhuatanga matua o tōna arotautanga mō te whakatikatika i ētahi āhuatanga o ngā piri taera.
I ēnei rā, ko te hanga, te tukatuka me te kai o te cellulose ether i tōku whenua kei te tūranga ārahi i te ao. Ko te whanaketanga me te whakamahinga tonu o te cellulose ether te mea nui ki te whanaketanga o ngā rauemi hanga hou i tōku whenua. Nā te whanaketanga tonu o ngā piri taera me te arotau tonu me te whakapai ake i tā rātou mahi, kua whakarei ake te kōwhiringa o ngā momo tono moata i roto i te mākete rauemi hanga hou. Heoi, ko te whanaketanga o te mākete piri taera te huarahi hou ki te arotau ake i te mahi matua o ngā piri taera.
1. Whakamātauria ngā rauemi mata
Sima: I whakamahia te sima Portland noa PO 42.5 i hangaia e Changchun Yatai i roto i tēnei whakamātautau.
Onepuku kuata: I whakamahia te 50-100 mata i tēnei whakamātautau, i hangaia ki Dalin, Mongolia o Roto.
Paura rapa ka taea te whakamarara anō: I whakamahia a SWF-04 i tēnei whakamātautau, i hangaia e Shanxi Sanwei.
Muka rakau: Ko te muka i whakamahia i tēnei whakamātautau i hangaia e Changchun Huihuang Building Materials.
Te etera cellulose: Ka whakamahia e tēnei whakamātautau te etera methyl cellulose me te matotoru o te 40,000, i hangaia e Shandong Ruitai.
2. Tikanga whakamātautau me te tātari hua
Ko te tikanga whakamātautau mō te kaha o te here kume e pā ana ki te paerewa JC/T547-2005. Ko te rahi o te wahi whakamātautau he 40mm x 40mm x 160mm. I muri i te hanganga, waiho kia tū mō te 1 rā, kātahi ka tangohia te anga. I whakamaroketia ki roto i te pouaka haumākū pumau mō ngā rā 27, i herea te pane tuhi ki te poraka whakamātautau ki te kapia epoxy, kātahi ka whakanohoia ki roto i te pouaka pāmahana me te haumākū pumau i te pāmahana o (23±2)°C me te haumākū whanaunga o (50±5)%. 1 rā, Tirohia te tauira mō ngā pakaru i mua i te whakamātautau. Tāutahia te taputapu ki te mīhini whakamātautau kume hiko whānui kia kore ai e piko te hononga i waenga i te taputapu me te mīhini whakamātautau, tōia te tauira i te tere o (250±50) N/s, ka tuhia ngā raraunga whakamātautau. Ko te nui o te sima i whakamahia i tēnei whakamātautau he 400g, ko te taumaha katoa o ētahi atu rauemi he 600g, ko te ōwehenga here-wai he 0.42 te mea pumau, ā, ka whakamahia he hoahoa orthogonal (3 ngā tauwehe, 3 ngā taumata), ko ngā tauwehe ko te nui o te cellulose ether, te nui o te paura rapa me te ōwehenga o te sima ki te onepu, e ai ki ngā wheako rangahau o mua hei whakatau i te horopeta motuhake o ia tauwehe.
2.1 Ngā hua whakamātautau me te tātari
I te nuinga o te wā, ka ngaro te kaha o te here o ngā piripiri taera i muri i te rumakina ki te wai.
Mai i ngā hua whakamātautau i whiwhihia e te whakamātautau orthogonal, ka kitea ko te whakanui ake i te nui o te cellulose ether me te paura rapa ka taea te whakapai ake i te kaha here kume o te piripiri taera ki tētahi taumata, ā, ko te whakaiti i te ōwehenga o te moata ki te onepu ka taea te whakaiti i tōna kaha here kume, engari ko te hua whakamātautau 2 i whiwhihia e te whakamātautau orthogonal kāore e taea te whakaata i te pānga o ngā āhuatanga e toru ki te kaha here kume o te piripiri taera uku i muri i te rumakina ki te wai me te hononga kume i muri i te 20 meneti o te whakamaroke. Nō reira, mā te matapaki i te uara whanaunga o te hekenga o te kaha here kume i muri i te rumakina ki te wai ka taea te whakaata pai ake i te awe o ngā āhuatanga e toru ki runga. Ko te uara whanaunga o te hekenga o te kaha ka whakatauhia e te kaha here kume taketake me te kaha kume i muri i te rumakina ki te wai. I tatauhia te ōwehenga o te rerekētanga o te kaha here ki te kaha here kume taketake.
E whakaatu ana te tātaritanga o ngā raraunga whakamātautau mā te whakanui ake i te ihirangi o te cellulose ether me te paura rapa, ka taea te whakapai ake i te kaha o te here kume i muri i te rumakina ki te wai. Ko te kaha o te here o te 0.3% he 16.0% teitei ake i te 0.1%, ā, ka kitea ake te whakapainga ina whakanuia te nui o te paura rapa; Ina 3% te nui, ka piki ake te kaha o te here mā te 46.5%; mā te whakaiti i te ōwehenga o te moata ki te onepu, ka taea te whakaiti nui i te kaha o te here kume i te rumakina ki te wai. Kua heke te kaha o te here mā te 61.2%. Ka kitea mā te whakaaro mai i te Pikitia 1, ina piki ake te nui o te paura rapa mai i te 3% ki te 5%, ka piki ake te uara whanaunga o te hekenga o te kaha o te here mā te 23.4%; ka piki ake te nui o te cellulose ether mai i te 0.1% ki te I roto i te tukanga o te 0.3%, ka piki ake te uara whanaunga o te hekenga o te kaha o te here mā te 7.6%; i te mea kua piki ake te uara whanaunga o te hekenga o te kaha o te here mā te 12.7% ina 1:2 te ōwehenga o te moata ki te onepu ki te 1:1. I muri i te whakataurite i te pikitia, ka kitea ngāwaritia i roto i ngā āhuatanga e toru, ko te nui o te paura rapa me te ōwehenga o te moata ki te onepu he pānga nui ake ki te kaha o te here kume o te rumaki wai.
E ai ki te JC/T 547-2005, ko te wā maroke o te piripiri taera he nui ake i te 20 meneti, he ōrite rānei. Mā te whakanui ake i te ihirangi o te cellulose ether ka piki haere te kaha o te hononga kume i muri i te hauhautanga mō te 20 meneti, ā, ko te ihirangi o te cellulose ether he 0.2%, 0.3%, ki te whakataurite ki te ihirangi o te 0.1%. I piki ake te kaha piri mā te 48.1% me te 59.6% ia; mā te whakanui ake i te nui o te paura rapa ka piki haere te kaha o te hononga kume i muri i te hauhautanga mō te 20 ua, ko te nui o te paura rapa he 4%, 5% % ki te whakataurite ki te 3%, ka piki ake te kaha o te hononga mā te 19.0% me te 41.4% ia; mā te whakaiti i te ōwehenga o te moata ki te onepu, ka heke haere te kaha o te hononga kume i muri i te 20 meneti o te hauhautanga, ā, ko te ōwehenga o te moata ki te onepu he 1:2. Ki te whakataurite ki te ōwehenga moata o te 1:1, ka heke te kaha o te hononga kume mā te 47.4%. Mā te whakaaro ki te uara whanaunga o te whakahekenga o tōna kaha here ka taea te whakaata mārama i te awe o ngā āhuatanga rerekē, mā roto i ngā āhuatanga e toru, ka kitea mārama ko te uara whanaunga o te whakahekenga o te kaha here kume i muri i te 20 meneti o te whakamaroke, i muri i te 20 meneti o te whakamaroke, kāore te pānga o te ōwehenga moata ki te kaha here kume i rite te nui ki mua, engari ko te pānga o te ihirangi cellulose ether kua kitea ake i tēnei wā. I te pikinga ake o te ihirangi o te cellulose ether, ka heke haere te uara whanaunga o tōna kaha, ā, he ngawari te piko. Ka kitea he pai te pānga o te cellulose ether ki te whakapai ake i te kaha here o te piripiri taera i muri i te 20 meneti o te whakamaroke.
2.2 Te whakatau tātai
Nā roto i ngā whakamātautau o runga ake nei, i riro mai ai he whakarāpopototanga o ngā hua o te hoahoa whakamātautau orthogonal.
Ka taea te tīpako i tētahi rōpū o ngā huinga A3 B1 C2 me te mahi tino pai mai i te whakarāpopototanga o ngā hua hoahoa o te whakamātautau orthogonal, arā, ko te ihirangi o te cellulose ether me te paura rapa he 0.3% me te 3%, ia, ā, ko te ōwehenga o te moata ki te onepu he 1:1.5.
3. Whakamutunga
(1) Mā te whakanui ake i te nui o te cellulose ether me te paura rapa ka taea te whakanui ake i te kaha here kume o te piripiri taera ki tētahi taumata, me te whakaiti i te ōwehenga o te moata ki te onepu, ka heke te kaha here kume, ā, ko te ōwehenga o te moata ki te onepu. Ko te pānga o te nui o te cellulose ether ki te kaha here kume o te piripiri taera uku i muri i te rumakina ki te wai he nui ake i te pānga o te nui o te cellulose ether ki runga;
(2) Ko te nui o te cellulose ether te mea nui rawa atu te pānga ki te kaha o te here kume o te piripiri taera i muri i te 20 meneti o te whakamaroke, e tohu ana mā te whakarerekē i te nui o te cellulose ether, ka taea te whakapai ake i te piripiri taera i muri i te 20 meneti o te whakamaroke. I muri i te kaha o te here kume;
(3) Ina 3% te nui o te paura rapa, 0.3% te nui o te cellulose ether, ā, 1:1.5 te ōwehenga o te moata ki te onepu, ka pai ake te mahi a te piripiri taera, koinei te mea pai rawa atu i tēnei whakamātautau. He pai te huinga taumata.
