Te whakamahinga me te tūranga o te cellulose ether i roto i ngā momo rauemi hanga whare

Ko te cellulose ether he momo polymer haurua-hangai kore-ionic me te wai-wairewa me te whakarewa-wairewa, e puta ai ngā tūranga rerekē i roto i ngā ahumahi rerekē, hei tauira, i roto i ngā rauemi hanga matū, kei a ia ngā tūranga matū e whai ake nei:

① kaihoko pupuri wai ② kaiwhakamātotoru ③ whakataurite ④ hanga kiriata ⑤ here

I roto i te umanga PVC, he emulsifier, he dispersant; i roto i te umanga rongoā, he here me ngā rauemi angaanga tuku puhoi me te whakahaere, me ētahi atu. Nā te mea he maha ngā mahi hiato a te cellulose, he whānui rawa ngā tono. Ko te kaupapa e whai ake nei e arotahi ana ki te whakamahinga me te tūranga o te cellulose ether i roto i ngā momo rauemi hanga.

(1) I roto i te putty pakitara:

I tēnei wā, i te nuinga o ngā tāone nui o tō tātou whenua, kua tino rongonui te putty ātete-wai, ātete-mirimiri, ā-taiao hoki e te tangata. I ngā tau tuatahi, nā te whakamahinga o te kāpia hangahanga i hangaia ki te putty e whakaputa ana i te hau formaldehyde e kino ana ki te hauora o te tangata, ka hangaia te kāpia hangahanga ki te waipiro polyvinyl me te formaldehyde acetal. Nō reira, ka āta tangohia e te tangata tēnei rauemi, ā, ka whakakapia tēnei rauemi ki ngā hua raupapa cellulose ether, arā, ko te whanaketanga o ngā rauemi hangahanga taiao, ko te cellulose anake te rauemi i tēnei wā.

I roto i te putty ātete-wai, ka wehea te putty paura maroke me te putty paste e rua ngā momo putty. Ko ēnei momo putty e rua te tikanga ki te whiriwhiri i te methyl cellulose whakarerekē me te hydroxypropyl methyl e rua ngā momo matotoru e rua, ko te tikanga he 30000-60000cps te matotoru e tika ana. Ko te mahi matua o te putty cellulose ko te pupuri i te wai, te here, te whakahinuhinu me ētahi atu mahi. Nā te mea he rerekē te tauira putty a ngā kaihanga rerekē, ko ētahi he konupūmā hina, he konupūmā māmā, he sima mā, me ētahi atu, ko ētahi he paura gypsum, he konupūmā hina, he konupūmā māmā, me ētahi atu, nō reira ko ngā tauira e rua hei whiriwhiri i te matotoru o te cellulose me tōna urunga kāore i te rite te nui, ko te nui o te urunga whānui he 2 ‰ -3 ‰ pea. I roto i te hanga putty pakitara waru, nā te mea he taumata mimiti wai te papa pakitara (ko te tere mimiti wai o te pakitara pereki he 13%, ko te raima he 3-5%), ā, ka honoa ki te ao o waho o te mimiti, nō reira, ki te tere rawa te ngaro o te wai i te putty, ka arahi ki ngā kapiti, ki te tango paura rānei me ētahi atu āhuatanga, ka ngoikore te kaha o te putty. Nā reira, i muri i te tāpiri i te cellulose ether ka whakatauhia tēnei raruraru. Engari he mea tino nui hoki te kounga o te whakakī, inā koa te kounga o te konupūmā hina.

Nā te mea he matotoru teitei te cellulose, nā reira ka whakarei ake i te piri o te putty, engari ka ārai hoki i te hanganga o te āhuatanga o te iri, me te waru i muri i te whakamarie ake, te penapena mahi me ētahi atu. I roto i te putty paura maroke me tika te tāpiri i te cellulose ether kia nui ake ai ngā tohu, kia watea ake ai te hanga, kia whakamahia ai, kia rite ai te whakakī me ngā tāpiringa mō te ranunga paura maroke, kia watea ake ai hoki te hanganga, kia pai ake ai te wai i te papaanga, kia rite ai te nui o te wai.

(2) te moata raima:

I roto i te moata raima, kia tino eke ki te kaha whakamutunga, me tino tauhohe te wai o te sima, inā koa i te raumati, he tere rawa te ngaronga o te wai o te moata raima, me mahi i ngā mahi hei tino wai mā te tiaki i te tauhiuhi. He moumou wai tēnei tikanga, he raruraru hoki ki te whakahaere. Ko te mea nui ko te wai kei runga noa i te mata, ā, kāore anō kia oti te wai o roto. Nō reira, ko te otinga ki te raruraru o te tikanga hono ki te moata raima ko te cellulose, he kaihoko pupuri wai, he tikanga whānui te whiriwhiri i te hydroxypropyl methyl, te methyl cellulose rānei. Ko ngā whakaritenga matotoru i waenga i te 20000 - 60000cps, tāpirihia te 2% - 3%. Tata ki te wā, ka taea te whakanui ake i te tere pupuri wai ki te neke atu i te 85%. Mā te whakamahi i te moata raima, ka taea te whakaranu i te paura maroke ki te wai.

(3) i roto i te paraikete stucco, te paraikete hononga, te paraikete tāmau:

I te tere o te whanaketanga o te umanga hanga, kei te piki haere hoki te hiahia o te tangata mō ngā rauemi hanga hou. Nā te pikinga ake o te mōhiotanga o te tangata ki te tiaki taiao me te whakapai tonu i te whai huatanga o te hanga, kua tere te whanaketanga o ngā hua rauemi sima, te gypsum. I tēnei wā, ko ngā hua gypsum tino noa ko te parai paraihe, te parai hono, te parai tāmau, te piri taera me ētahi atu. Ko te parai paraihe he momo rauemi parai kounga teitei mō te pakitara o roto me te papa o runga, he maeneene, he maeneene te mata o te pakitara, kāore he paura e taka ana, ā, he piri pakari te papa me te kore e pakaru, e taka ana, ā, he mahi ātete ahi; ko te parai hono he momo hou o te kaihoko here papa rama hanga, he mea hanga ki te gypsum hei rauemi turanga, ā, he maha ngā tāpiringa kua tāpirihia, ā, he pai mō te here i ngā momo rauemi pakitara hanga kore-waro katoa, me ngā āhuatanga o te kore-paitini, te kore-reka, te tere o te whakapūmau me te tere o te here. He pai mō te hono i waenga i ngā momo rauemi pakitara hanga kore-waro, kāore he paitini, kāore he kakara, he tere te totoka, he pakari te hononga me ētahi atu āhuatanga, ā, he rauemi tautoko mō te hanganga o ngā papa hanga me ngā poraka; he whakakī āputa te gypsum caulk i waenga i ngā papa gypsum me te whakakī whakatika mō ngā pakitara me ngā kapiti.

He maha ngā mahi a ēnei hua gypsum, hei tāpiri atu ki te gypsum me ngā whakakī e pā ana, ko te take matua ko te tāpiri i ngā tāpiringa cellulose ether he mahi matua. Nā te mea kua wehea te gypsum ki te gypsum korewai me te gypsum haurua-korewai, he rerekē ngā pānga o ngā gypsum rerekē ki te mahi a te hua, nō reira ko te matotoru, te pupuri wai me te whakaroa o ngā rauemi hanga gypsum ka whakatau i te kounga o ngā rauemi hanga gypsum. Ko te raru noa o ēnei rauemi ko te poka me te ngatata, kāore e taea te whakatutuki i te kaha tuatahi, hei whakaoti i tēnei raruraru, ko te whiriwhiri i te momo cellulose me te whakamahinga o te raruraru whakaroa, i tēnei whakaaro, ko te whiriwhiri whānui o te methyl, te methyl rānei te waikawaroporopimetila 30,000 - 60,000cps, ko te nui o te tāpiri he 1.5% - 2%. I waenganui, ko te cellulose te arotahi ki te whakahinuhinu pupuri wai. Heoi, i tēnei wā, kāore e taea te whakawhirinaki ki te cellulose ether hei whakaroa, me tāpiri hoki te whakaroa waikawa citric i te whakamahinga whakaranu, kāore e pā ki te kaha tīmatanga.

Ko te auau pupuri wai e pā ana ki te āhua o te korenga o te mimiti wai o waho, ko te nui o te ngaronga wai tūturu. Ki te maroke te pakitara, ka tere rawa te mimiti wai o te mata o raro, ka mimiti wai tūturu, ka memeha haere te rauemi, ka puta he oko tuwhera, ka pakaru. Mō te whakamahinga whakauru o te paura maroke, ki te whakarite i te otinga, ka taea te kī ko te whakarite i te otinga.

(4) Moata whakamahana wera

Ko te moata whakamahana wera he momo rauemi whakamahana pakitara o roto hou, he rauemi pakitara i hangaia mai i ngā rauemi whakamahana wera, te moata me te here. Ko te cellulose i roto i tēnei rauemi, e aro ana ki te here, ka whakanui ake i te kaha. Ko te nuinga o te wā ka whiriwhiria metiloro he matotoru teitei (10000cps pea), ko te horopeta i waenga i te 2‰-3‰, ka whakamahia te tikanga whakaranu paura maroke.
